For example, the first peep-proof structure 120 can be switched between the first state and the second state by an electrical signal or other suitable means, but is not limited thereto. As shown in fig. 4, when the first privacy structure 120 is in the first state (sharing state), the user can view the display device 100 in the first viewing angle range VA1 (i.e., the display device 100 has the first viewing angle range VA 1), and when the first privacy structure 120 is in the second state (privacy state or privacy state), the user can view the display device 100 in the second viewing angle range VA2 (i.e., the display device 100 has the second viewing angle range VA 2), wherein the first viewing angle range VA1 is larger than the second viewing angle range VA2. That is, at some specific angles, if the first peep-proof structure 120 is in the first state (sharing state), the user can view the display screen of the display device 100, but if the first peep-proof structure 120 is in the second state (peep-proof state or privacy state), the user cannot view or cannot clearly view the display screen of the display device 100. It should be noted that, when the user is facing the display device 100, the angle between the viewing line of sight of the user and the normal direction (e.g., direction Z) of the light emitting surface of the display device 100 is 0 degrees. In addition, in the case that the first peep-preventing structure 120 is a controllable peep-preventing structure, when the first peep-preventing structure 120 is in the first state or the second state, the light incident into the first peep-preventing structure 120 can be adjusted and/or screened, so that the light emitted from the first peep-preventing structure 120 accords with the current state of the first peep-preventing structure 120, so as to close or open the peep-preventing function.
In some embodiments (as shown in fig. 3 and 4), the first peep-preventing structure 120 may be an electrically controlled peep-preventing structure, so that a user can control the opening and closing of the peep-preventing function of the first peep-preventing structure 120 through an electrical signal. The first privacy structure 120 may include a light control substrate, wherein the light control substrate may be a hard substrate or a flexible substrate, and may include glass, plastic, quartz, sapphire, polyimide, polyethylene terephthalate, other suitable materials or combinations thereof, for example, but not limited thereto. For example, in fig. 3 and 4, the first peep-preventing structure 120 may include a first light-controlling substrate 122 and a second light-controlling substrate 128, and the materials, shapes and dimensions of the first light-controlling substrate 122 and the second light-controlling substrate 128 may be the same or different from each other, but are not limited thereto.
In the first privacy structure 120 shown in fig. 3 and 4, a light control dielectric layer, which may include any suitable liquid crystal molecules, and a light control electrode, which may include a transparent conductive material, for example, are disposed between the first light control substrate 122 and the second light control substrate 128. The transparent conductive material may be, for example, but not limited to, indium Tin Oxide (ITO). It should be noted that the material of the light control medium layer may be the same as or different from the material of the display medium layer 116 of the display panel 110. For example, the light control medium layer of the first privacy structure 120 and the display medium layer 116 of the display panel 110 may each include liquid crystal molecules, and the types of the liquid crystal molecules of the light control medium layer may be the same or different from the types of the liquid crystal molecules of the display medium layer 116 of the display panel 110, but not limited thereto. The first light-shielding structure 120 may include a first light-shielding layer 126, a first light-shielding electrode 124a and a second light-shielding electrode 124b, wherein an electrical signal is applied to the first light-shielding electrode 124a and the second light-shielding electrode 124b (e.g., a voltage is applied to the first light-shielding electrode 124a and another voltage is applied to the second light-shielding electrode 124 b) respectively to control the state of the first light-shielding layer 126 (e.g., control the direction of the liquid crystal molecules in the first light-shielding layer 126 or control the first light-shielding layer 126 to be in a transparent state or a scattering state), so as to regulate the light-emitting viewing angle range after the light passes through the first light-shielding structure 120, so that the first light-shielding structure 120 is in the first state or the second state. For example, the first light control medium layer 126 may be disposed between the first light control electrode 124a and the second light control electrode 124b in the direction Z, the first light control electrode 124a is disposed between the first light control substrate 122 and the first light control medium layer 126, and the second light control electrode 124b is disposed between the second light control substrate 128 and the first light control medium layer 126, but not limited thereto. In the present embodiment, the first light control electrode 124a may be disposed in the entire area of the active region 120A of the first peep-preventing structure 120, and the second light control electrode 124a may be disposed in the entire area of the active region 120A of the first peep-preventing structure 120, that is, all the areas of the active region 120A of the first peep-preventing structure 120 are disposed with the first light control electrode 124a and the second light control electrode 124b, but not limited thereto.
In addition, in some embodiments, the first peep-preventing structure 120 may further include two alignment films (not shown), wherein one alignment film is disposed between the first light control electrode 124a and the first light control medium layer 126, the other alignment film is disposed between the second light control electrode 124b and the first light control medium layer 126, and each alignment film may be disposed in the entire area of the active region 120A of the first peep-preventing structure 120.
In some embodiments, the first peep-preventing structure 120 may further optionally include a sealant layer (not shown) disposed between the first light control substrate 122 and the second light control substrate 128 to join the first light control substrate 122 and the second light control substrate 128, and the first light control medium layer 126 is located in a space formed by the first light control substrate 122, the second light control substrate 128 and the sealant layer.
In fig. 4, the voltage difference between the first light control electrode 124a and the second light control electrode 124b can be controlled to adjust the first light control medium layer 126, so that the first peep-proof structure 120 can be switched between the first state and the second state, and the direction of the light emitted from the first peep-proof structure 120 can be correspondingly adjusted. In some embodiments, the absolute value of the voltage difference (i.e., the first voltage difference) between the first light control electrode 124a and the second light control electrode 124b in the first state is different from the absolute value of the voltage difference (i.e., the second voltage difference) between the first light control electrode 124a and the second light control electrode 124b in the second state. For example, when the voltage difference between the first light control electrode 124a and the second light control electrode 124b is larger (or smaller), the first privacy structure 120 may be in the first state; when the voltage difference between the first light control electrode 124a and the second light control electrode 124b is smaller (or larger), the first privacy structure 120 can be in the second state, but is not limited thereto. In some embodiments, the first light control electrode 124a and/or the second light control electrode 124b in the first state float (float), and there is a voltage difference greater than zero between the first light control electrode 124a and the second light control electrode 124b in the second state. In some embodiments, when collimated light is incident on the first peep-preventing structure 120, the first peep-preventing structure 120 in the first state (sharing state) may diffuse the collimated light such that the light emitted from the first peep-preventing structure 120 is scattered light, and the first peep-preventing structure 120 in the second state (peep-preventing state or privacy state) may not adjust the collimated light or slightly adjust the collimated light such that the light emitted from the first peep-preventing structure 120 is collimated light or near collimated light, but is not limited thereto. In some embodiments, when non-collimated light (e.g., scattered light) is incident on the first peep-preventing structure 120, the first peep-preventing structure 120 in the first state (sharing state) may adjust the non-collimated light or slightly adjust the non-collimated light so that the light emitted from the first peep-preventing structure 120 is scattered light, and the first peep-preventing structure 120 in the second state (peep-preventing state or privacy state) may adjust (e.g., collimate) the non-collimated light so that the light emitted from the first peep-preventing structure 120 is collimated light or approximately collimated light, but is not limited thereto.
As shown in fig. 1 to 4, the display device 100 may include a cover 130 for protecting components and structures disposed on a first side thereof, wherein the display panel 110 and the first peep-proof structure 120 are disposed on the first side of the cover 130. The material of the cover plate 130 may include glass, plastic, quartz, sapphire, polyimide, polyethylene terephthalate, other suitable materials, or combinations thereof, but is not limited thereto. It should be noted that, in fig. 3 and fig. 4, the lower surface 130a of the cover 130 may be adjacent to the first side of the cover 130, the upper surface 130b of the cover 130 opposite to the lower surface 130a may be far away from the first side of the cover 130, and the upper surface 130b of the cover 130 may be the light emitting surface of the display device 100.
In the present invention, the cover plate 130, the display panel 110 and the first privacy structure 120 overlap each other in a top view (i.e., direction Z). For example, in the present embodiment (as shown in fig. 3 and 4), the display panel 110 may be disposed between the first privacy structure 120 and the cover 130, and the display panel 110 may be a non-self-luminous display panel, but is not limited thereto. In this context, the normal direction of the light exit surface of the display device 100, the normal direction of the first peep-preventing structure 120, the normal direction of the display panel 110, the normal direction of the cover 130, and the top view direction are all directions Z. Specifically, herein, the normal direction of the light exit surface of the display device 100 is a direction perpendicular to the light exit surface of the display device 100, the normal direction of the first peep-proof structure 120 is a direction perpendicular to the upper surface of the first peep-proof structure 120, the normal direction of the display panel 110 is a direction perpendicular to the upper surface of the display panel 110, and the normal direction of the cover plate 130 is a direction perpendicular to the upper surface of the cover plate 130.
As shown in fig. 1 to 4, the display device 100 may include a light sensing device 140 disposed on a first side of the cover 130 and configured to sense light. In some embodiments, the light sensing device 140 is used for sensing the light of the external environment. In addition, in the present invention, the light sensing device 140 may include any suitable light sensing element. For example, the light sensing device 140 may be a Camera Lens (Camera Lens), but is not limited thereto.
In a display device having a display panel, a peep-proof structure, and a light sensing device such as a photographing lens, if the light sensing device is disposed below the display panel and the peep-proof structure and overlaps the display panel and the peep-proof structure, when the light sensing device senses light, external light needs to pass through a cover plate, the peep-proof structure, and the display panel to reach the light sensing device, so that the light intensity received by the light sensing device is weakened, and the light sensing device can have poor photographing effect (e.g., poor imaging quality) due to shielding of the peep-proof structure and the display panel (incomplete transparency of the peep-proof structure and the display panel). In addition, when the light sensing device is disposed below the display panel and the peep-proof structure and overlaps the display panel and the peep-proof structure, the overall thickness of the display device is also thicker, which is not in line with the current trend of light and thin.
In order to avoid the above problems, in the present invention, as shown in fig. 1 to 4, the first peep-preventing structure 120 has a first hollow portion 120v, the display panel 110 has a second hollow portion 110v, and the second hollow portion 110v of the display panel 110 overlaps the first hollow portion 120v of the first peep-preventing structure 120 in a top view (i.e., a direction Z), wherein the light sensing device 140 overlaps the first hollow portion 120v and the second hollow portion 110v in a top view. The light sensing device 140 is located in the first hollow portion 120v and the second hollow portion 110v in a top view (i.e., the light sensing device 140 does not overlap the first peep-proof structure 120 and the display panel 110 in the direction Z), and the light sensing device 140 is disposed in the first hollow portion 120v and the second hollow portion 110v (as shown in fig. 3). As shown in fig. 3, the light sensing device 140 passes through the first hollowed-out portion 120v and the second hollowed-out portion 110v, but not limited thereto. Specifically, in the present embodiment, the display panel 110 and the first peep-preventing structure 120 are stacked to form the peep-preventing display module PD1, the first hollowed portion 120v and the second hollowed portion 110v are stacked and connected to each other to form the hollowed area TH1 penetrating the peep-preventing display module PD1, the light sensing device 140 overlaps the hollowed area TH1 in a top view, and the light sensing device 140 is disposed in the hollowed area TH1 (as shown in fig. 3). Therefore, under this design, when the light sensing device 140 performs light sensing, the external light can be received by the light sensing device 140 through the cover plate 130 but not through the first peep-proof structure 120 and the display panel 110, so that the light sensing device 140 can receive the external light with stronger light intensity, thereby improving the shooting effect and the sensing effect of the light sensing device 140.
In addition, in the present embodiment, since the light sensing device 140 is disposed in the first hollowed-out portion 120v of the first peep-proof structure 120 and the second hollowed-out portion 110v of the display panel 110 (as shown in fig. 3), the overall thickness of the display device 100 can be reduced.
Since the first peep-preventing structure 120 has the first hollowed-out portion 120v, the first peep-preventing structure 120 does not have any film layer and structure of the first peep-preventing structure 120 in the area where the first hollowed-out portion 120v is located. Since the display panel 110 has the second hollowed-out portion 110v, the display panel 110 does not have any film layer and structure of the display panel 110 in the area where the second hollowed-out portion 110v is located.
In some embodiments, the first hollowed-out portion 120v of the first peep-proof structure 120 and the second hollowed-out portion 110v of the display panel 110 may have a through hole or a groove in top view, but not limited thereto. For example, in fig. 1 and 2, the first hollowed-out portion 120v of the first peep-proof structure 120 and the second hollowed-out portion 110v of the display panel 110 are concave in shape in a top view, but not limited thereto. Referring to fig. 5, fig. 5 is a schematic perspective view of a display panel, a first peep-proof structure and a light sensing device according to a variation of the first embodiment of the invention. As shown in fig. 5, the present variation differs from the first embodiment in the shape of the hollowed-out portion. In the display device 100A shown in fig. 5, the first hollowed-out portion 120v of the first peep-proof structure 120 and the second hollowed-out portion 110v of the display panel 110 are perforated in shape in a plan view.
In addition, the display device 100 may further include a required film layer and a required structure according to requirements. In fig. 3 to 4, since the display panel 110 is a non-self-luminous display panel, the display device 100 may include a backlight module 150 to provide backlight to the display panel 110, wherein the display panel 110 and the first peep-preventing structure 120 may be disposed between the backlight module 150 and the cover 130. For example, in fig. 3 and 4, the cover 130, the first peep-preventing structure 120, the display panel 110 and the backlight module 150 overlap each other in a top view, and the first peep-preventing structure 120 may be disposed between the display panel 110 and the backlight module 150 (i.e. the first peep-preventing structure 120 is located at the light incident side of the display panel 110), but not limited thereto. In the present invention, the backlight module 150 may be any suitable backlight module, such as a direct type (direct type) backlight module, a side-entry type (Edge lit) backlight module, or other types of backlight modules, and the backlight module 150 may emit collimated light (e.g., collimated backlight module) or scattered light according to requirements.
In fig. 3 and fig. 4, the light provided by the backlight module 150 sequentially passes through the first peep-preventing structure 120, the display panel 110 and the cover 130. That is, the light rays are first incident into the first peep-preventing structure 120, the first peep-preventing structure 120 adjusts the light emitting viewing angle range of the backlight module 150 after passing through the first peep-preventing structure 120 according to the state thereof, and then the light rays are incident into the display panel 110, and the display panel 110 passes through the light rays with corresponding intensities according to the corresponding gray-scale signals to display the corresponding images.
Alternatively, the backlight module 150 may also have a hollowed-out portion (e.g. a through hole or a groove) overlapping the first hollowed-out portion 120v and the second hollowed-out portion 110v in the normal direction (direction Z) of the cover 130, and the light sensing device 140 overlaps the hollowed-out portion of the backlight module 150 in the direction Z, but is not limited thereto. That is, the backlight module 150 does not overlap the first and second cutouts 120v and 110v in a plan view.
Optionally, as shown in fig. 3, the display panel 110 may further include a touch sensing element 160 for performing touch sensing to detect a position or an action of a touch member (e.g. a stylus, a finger, etc.), wherein the touch sensing element 160 may perform sensing in any suitable manner. For example, the touch sensing device 160 may sense by capacitive means, such as self-capacitance (self-capacitance) or mutual-capacitance (mutual-capacitance), but is not limited thereto.
The touch sensing element 160 can be disposed at any suitable location according to the requirement. For example, in fig. 3, the touch sensing device 160 may be disposed On the upper surface of the second substrate 118 of the display panel 110 to form an embedded (On-Cell) touch sensing panel 110T, but is not limited thereto. In the display device 100, the touch sensing element 160 is disposed between the second substrate 118 and the cover 130 of the display panel 110, but not limited thereto. In some embodiments, the touch sensing element 160 may be disposed between the first substrate 112 and the second substrate 118 of the display panel 110 to form an In-Cell touch sensing panel.
The touch sensing device 160 may include a plurality of touch sensing electrodes 162, and the touch sensing electrodes 162 may be arranged according to the requirement as a unit for touch sensing. The touch sensing electrode 162 may include a transparent conductive layer or a metal mesh (metal mesh), but is not limited thereto. For example, the transparent conductive layer may include a transparent conductive material (such as indium tin oxide), but is not limited thereto. The touch sensing element 160 may further include at least one connection line (not shown) electrically connected to the corresponding touch sensing electrode 162 for transmitting and/or receiving a touch sensing signal.
The display device of the present invention is not limited to the above embodiments, and other embodiments will be further disclosed herein, however, for simplicity of description and highlighting the differences between the embodiments and the above embodiments, the same reference numerals are used to designate the same elements, and overlapping parts will not be repeated.
Referring to fig. 6 to 8, fig. 6 is a schematic top view of a display device according to a second embodiment of the invention, fig. 7 is a schematic perspective view of a display panel, a first peep-proof structure and a light sensing device according to the second embodiment of the invention, and fig. 8 is a schematic cross-sectional view taken along line B-B' of fig. 6. In the display device 200 shown in fig. 6 to 8, the first hollowed-out portion 120v of the first peep-proof structure 120 and the second hollowed-out portion 110v of the display panel 110 may be perforated in a top view, but not limited thereto. In a variation of the present embodiment, the shapes of the first hollowed-out portion 120v of the first peep-proof structure 120 and the second hollowed-out portion 110v of the display panel 110 may be similar to the grooves of fig. 1 and 2, and will not be repeated here.
As shown in fig. 8, the difference between the present embodiment and the first embodiment is the relative position of the first peep-proof structure 120 and the display panel 110. In the display device 200 shown in fig. 8, the first peep-proof structure 120 may be disposed between the display panel 110 and the cover 130 (i.e. the first peep-proof structure 120 is located on the light-emitting side of the display panel 110). In this design, the display panel 110 may be a self-luminous display panel or a non-self-luminous display panel. In addition, the non-self-luminous display panel may be a transmissive non-self-luminous display panel or a reflective non-self-luminous display panel, but is not limited thereto. In the aspect that the display panel 110 is a transmissive non-self-luminous display panel, the display panel 110 of the present embodiment and its modified embodiments is similar to the display panel 110 of the first embodiment, and the display device 200 may further include a backlight module (not shown) disposed on the light incident side of the display panel 110 (i.e. the display panel 110 is disposed between the first peep-preventing structure 120 and the backlight module). In the aspect that the display panel 110 is a reflective non-self-luminous display panel, the display device may include a reflective electrode, and the reflective electrode is configured to reflect ambient light to display a picture. In addition, in some embodiments in which the display panel 110 is a reflective non-self-luminous display panel, the display device 200 may further include a front light module (not shown) disposed on a light emitting side of the display panel 110 (i.e., the front light module is disposed between the display panel 110 and the first peep-preventing structure 120). In the aspect that the display panel 110 is a self-luminous display panel, the display element may include a light emitting element (e.g., a light emitting diode), where the light emitting element of the display panel 110 emits light with a corresponding intensity according to the gray-scale signal to display a picture. In the case where the display panel 110 is a reflective non-self-luminous display panel or a self-luminous display panel, the display device 200 does not need to include a backlight module. After the light rays passing through the display panel 110, the light rays reflected by the display panel 110 or the light rays emitted by the light emitting element of the display panel 110 are incident into the first peep-proof structure 120, the first peep-proof structure 120 can regulate the light-emitting visual angle range of the light rays passing through the first peep-proof structure 120 according to the state thereof, so that the picture displayed by the display panel 110 is in a sharing state or a peep-proof state.
As shown in fig. 6 to 8, the second hollowed portion 110v of the display panel 110 overlaps the first hollowed portion 120v of the first peep-proof structure 120 in a top view (i.e., a direction Z), and the light sensing device 140 overlaps the first hollowed portion 120v and the second hollowed portion 110v in the direction Z. The photo-sensing device 140 is located in the first hollow portion 120v and the second hollow portion 110v in a top view, and the photo-sensing device 140 is disposed in the second hollow portion 110v and the first hollow portion 120v (as shown in fig. 8). As shown in fig. 8, the light sensing device 140 passes through the first hollowed-out portion 120v and the second hollowed-out portion 110v, but not limited thereto. Specifically, in the present embodiment, the display panel 110 and the first peep-preventing structure 120 are stacked to form the peep-preventing display module PD2, the first hollowed portion 120v and the second hollowed portion 110v are stacked and connected to each other to form the hollowed portion TH2 penetrating through the peep-preventing display module PD2, the light sensing device 140 overlaps the hollowed portion TH2 in a top view, and the light sensing device 140 is disposed in the hollowed portion TH2 (as shown in fig. 8).
Optionally, as shown in fig. 8, the first privacy structure 120 may further include a touch sensing element 160. In fig. 8, the touch sensing element 160 may be disposed on the upper surface of the second light control substrate 128 of the first peep preventing structure 120 to form an embedded touch sensing peep preventing structure 120T, but is not limited thereto. In the display device 200, the touch sensing element 160 is disposed between the second light control substrate 128 and the cover 130 of the first privacy structure 120, but not limited thereto. In some embodiments, the touch sensing element 160 may be disposed between the first light control substrate 122 and the second light control substrate 128 of the first privacy structure 120 to form an in-cell touch sensing privacy structure. The touch sensing device 160 may include a plurality of touch sensing electrodes 162, and the touch sensing electrodes 162 may be arranged according to the requirement as a unit for touch sensing. The touch sensing element 160 and the touch sensing electrode 162 in the present embodiment are similar to the touch sensing element 160 and the touch sensing electrode 162 in the first embodiment, and will not be described herein.

In the present embodiment, the cover plate 130, the second peep-preventing structure 320, the display panel 110 and the first peep-preventing structure 120 overlap each other in a top view (i.e., in the direction Z). The second privacy structure 320 includes an active region 320A and a peripheral region 320P. The active area 320A of the second peep-preventing structure 320 corresponds to the display area 110A of the display panel 110, and the peripheral area 320P of the second peep-preventing structure 320 corresponds to the peripheral area 110P of the display panel 110, that is, the active area 320A of the second peep-preventing structure 320 overlaps the display area 110A of the display panel 110 and the active area 120A of the first peep-preventing structure 120 in the direction Z, and the peripheral area 320P of the second peep-preventing structure 320 overlaps the peripheral area 110P of the display panel 110 and the peripheral area 120P of the first peep-preventing structure 120 in the direction Z, but is not limited thereto.
The second peep-proof structure 320 has a peep-proof function for the display screen, where the second peep-proof structure 320 is not particularly limited, and the peep-proof function can be performed by any suitable manner. In the present invention, the second peep-proof structure 320 may be a controllable peep-proof structure (refer to the description of the first peep-proof structure 120).
As shown in fig. 11, the second peep-preventing structure 320 may be an electrically controlled peep-preventing structure, so that a user can control the opening and closing of the peep-preventing function of the second peep-preventing structure 320 through an electrical signal. The second privacy structure 320 may include a light control substrate, wherein the light control substrate may be a hard substrate or a flexible substrate, and may include glass, plastic, quartz, sapphire, polyimide, polyethylene terephthalate, other suitable materials or combinations thereof, for example, but not limited thereto.

The transparent conductive material may be, for example, but not limited to, indium Tin Oxide (ITO). It should be noted that the material of the light control medium layer may be the same as or different from the material of the display medium layer 116 of the display panel 110. For example, the second light shielding structure 320 may include a second light shielding medium layer 326, a third light shielding electrode 324a and a fourth light shielding electrode 324b, wherein an electrical signal is applied to the third light shielding electrode 324a and the fourth light shielding electrode 324b (e.g., a voltage is applied to the third light shielding electrode 324a and another voltage is applied to the fourth light shielding electrode 324 b) to control the state of the second light shielding medium layer 326, so as to regulate the light emergent angle range after passing through the second light shielding structure 320, and make the second light shielding structure 320 in the first state (sharing state) or the second state (privacy state or privacy state). For example, the second light control medium layer 326 may be disposed between the third light control electrode 324a and the fourth light control electrode 324b in the direction Z, but is not limited thereto. In the present embodiment, the third light control electrode 324a may be disposed in the entire area of the active region 320A of the second peep-preventing structure 320, and the fourth light control electrode 324b may be disposed in the entire area of the active region 320A of the second peep-preventing structure 320, that is, all the areas of the active region 320A of the second peep-preventing structure 320 are disposed with the third light control electrode 324a and the fourth light control electrode 324b, but not limited thereto. In addition, in some embodiments, the second peep-preventing structure 320 may further include two alignment films (not shown), wherein one alignment film is disposed between the third light control electrode 324a and the second light control medium layer 326, the other alignment film is disposed between the fourth light control electrode 324b and the second light control medium layer 326, and each alignment film may be disposed in the entire area of the active region 320A of the second peep-preventing structure 320.
In fig. 11, the second light control medium layer 326 can be adjusted by controlling the voltage difference between the third light control electrode 324a and the fourth light control electrode 324b, so that the second peep-proof structure 320 can be switched between the first state and the second state, and the direction of the light emitted from the second peep-proof structure 320 can be correspondingly adjusted. The absolute value of the voltage difference between the third light control electrode 324a and the fourth light control electrode 324b in the first state (shared state) is different from the absolute value of the voltage difference between the third light control electrode 324a and the fourth light control electrode 324b in the second state (privacy state). The operation of the second peep-proof structure 320 in this embodiment may be similar to that of the first peep-proof structure 120 described above, and the detailed description is omitted herein. Compared to the display devices 100 and 200 having one peep-preventing structure (i.e., the first peep-preventing structure 120) in the first embodiment and the second embodiment, the display device 300 of the present embodiment includes two peep-preventing structures (i.e., the first peep-preventing structure 120 and the second peep-preventing structure 320), so that the peep-preventing effect can be enhanced. For example, compared with a display device only comprising one peep-proof structure, the display device comprising two peep-proof structures can further reduce the brightness of the predetermined peep-proof viewing angle so as to improve the peep-proof efficacy. It should be noted that in some embodiments, the second privacy structure 320 may operate differently than the first privacy structure 120, or the second privacy structure 320 may operate differently than the first privacy structure 120.
The second peep-proof structure 320 may have a third hollow 320v, the third hollow 320v may overlap the first hollow 120v of the first peep-proof structure 120 and the second hollow 110v of the display panel 110 in a top view (direction Z), and the light sensing device 140 overlaps the first hollow 120v, the second hollow 110v and the third hollow 320v in a top view. The light sensing device 140 may be located in the first hollowed portion 120v, the second hollowed portion 110v, and the third hollowed portion 320v in a top view (i.e., the light sensing device 140 does not overlap the first peep-preventing structure 120, the display panel 110, and the second peep-preventing structure 320 in the direction Z). In fig. 11, the light sensing device 140 is disposed in the first hollow portion 120v, the second hollow portion 110v and the third hollow portion 320v, but not limited thereto. As shown in fig. 11, the light sensing device 140 passes through the first hollow portion 120v, the second hollow portion 110v and the third hollow portion 320v, but not limited thereto. Specifically, in the present embodiment, the display panel 110, the first peep-preventing structure 120 and the second peep-preventing structure 320 are stacked to form the peep-preventing display module PD3, the first hollowed-out portion 120v, the second hollowed-out portion 110v and the third hollowed-out portion 320v are stacked and connected to each other to form the hollowed-out area TH3 penetrating through the peep-preventing display module PD3, the light sensing device 140 overlaps the hollowed-out area TH3 in a top view, and the light sensing device 140 is disposed in the hollowed-out area TH3 (as shown in fig. 11). Since the second peep-proof structure 320 has the third hollowed-out portion 320v, the second peep-proof structure 320 does not have any film layer and structure of the second peep-proof structure 320 in the area where the third hollowed-out portion 320v is located.
Optionally, as shown in fig. 11, the second privacy structure 320 may further include a touch sensing element 160. The second peep-proof structure 320 may be an embedded touch sensing peep-proof structure 320T, and the touch sensing element 160 may be disposed on an upper surface of the fourth light control substrate 328 of the second peep-proof structure 320. In the display apparatus 300, the touch sensing device 160 is disposed between the fourth light control substrate 328 of the second peep-proof structure 320 and the cover 130, but not limited thereto. In some embodiments, the touch sensing element 160 may be disposed between the third light control substrate 322 and the fourth light control substrate 328 of the second privacy structure 320 to form an in-cell touch sensing privacy structure. The touch sensing device 160 may include a plurality of touch sensing electrodes 162, and the touch sensing electrodes 162 may be arranged according to the requirement as a unit for touch sensing. The touch sensing element 160 and the touch sensing electrode 162 in the present embodiment are similar to the touch sensing element 160 and the touch sensing electrode 162 in the second embodiment, and will not be described herein.
Fig. 12 is a schematic cross-sectional view of a display device according to a variation of the third embodiment of the present invention, and fig. 13 is a schematic cross-sectional view of a display device according to another variation of the third embodiment of the present invention. The top view of these two alternative embodiments is similar to that of fig. 9, and fig. 12 and 13 are schematic cross-sectional views taken along line C-C' of fig. 9. As shown in fig. 11 to 13, the difference between the two modified embodiments and the fourth embodiment is that the relative positions of the first peep-preventing structure 120, the display panel 110 and the second peep-preventing structure 320 are different. As shown in fig. 11, in the third embodiment, the display panel 110 is located between two peep-preventing structures (i.e., the first peep-preventing structure 120 and the second peep-preventing structure 320). As shown in fig. 12 and 13, the two peep-preventing structures (i.e., the first peep-preventing structure 120 and the second peep-preventing structure 320) of either of these two variant embodiments (i.e., the display devices 300A, 300B) are located on the same side of the display panel 110. For example, the first peep-preventing structure 120 and the second peep-preventing structure 320 are both located on the light incident side of the display panel 110 (as shown in fig. 12, the first peep-preventing structure 120 and the second peep-preventing structure 320 are located between the backlight module 150 and the display panel 110), or the first peep-preventing structure 120 and the second peep-preventing structure 320 are both located on the light emitting side of the display panel 110 (as shown in fig. 13, the display panel 110 is located between the backlight module 150 and the first peep-preventing structure 120, and the first peep-preventing structure 120 is located between the display panel 110 and the second peep-preventing structure 320). In both of these variant embodiments, the first cutout 120v of the first privacy structure 120, the second cutout 110v of the display panel 110, and the third cutout 320v of the second privacy structure 320 overlap in the direction Z. The photo-sensing device 140 overlaps the first, second and third hollows 120v, 110v and 320v in a plan view, and the photo-sensing device 140 may be located in the first, second and third hollows 120v, 110v and 320v in a plan view. In fig. 12 and 13, the photo-sensing device 140 is disposed in the first hollow portion 120v, the second hollow portion 110v and the third hollow portion 320v, but not limited thereto. As shown in fig. 12 and 13, the light sensing device 140 passes through the first hollow portion 120v, the second hollow portion 110v and the third hollow portion 320v, but is not limited thereto. Specifically, in these two modified embodiments, the display panel 110, the first peep-preventing structure 120 and the second peep-preventing structure 320 are stacked to form the peep-preventing display module PD3A or PD3B, the first hollowed-out portion 120v, the second hollowed-out portion 110v and the third hollowed-out portion 320v are stacked and connected to each other to form a hollowed-out area TH3A penetrating the peep-preventing display module PD3A or a hollowed-out area TH3B penetrating the peep-preventing display module PD3B, the light sensing device 140 overlaps the hollowed-out area TH3A or TH3B in a top view, and the light sensing device 140 is disposed in the hollowed-out area TH3A or TH3B (as shown in fig. 12 and 13).
In addition, in the present embodiment and the modified embodiment of the present embodiment, the shapes of the first hollowed-out portion 120v of the first peep-proof structure 120, the second hollowed-out portion 110v of the display panel 110, and the third hollowed-out portion 320v of the second peep-proof structure 320 may also be changed to be similar to the perforations of fig. 5 and fig. 7, and will not be repeated here.
Referring to fig. 14 to 17, fig. 14 is a schematic top view of a display device according to a fourth embodiment of the invention, fig. 15 is a schematic perspective view of a display panel, a first peep-proof structure and a light sensing device according to the fourth embodiment of the invention, fig. 16 is a schematic cross-sectional view along a line D-D' of fig. 14, and fig. 17 is a schematic cross-sectional view of the display panel of the display device according to the fourth embodiment of the invention at the light sensing portion. For brevity, fig. 16 omits to show the detailed structures (such as the first substrate 112, the second substrate 118, the circuit element layer 114 and the display medium layer 116) in the display panel 110, and the related description of the display panel 110 of the present embodiment may refer to the first embodiment. As shown in fig. 14 to 17, the difference between the present embodiment and the first embodiment is the design of the display panel 110 of the present embodiment. In the display device 400, the display panel 110 does not have a hollowed portion, and the first peep-proof structure 120 has a first hollowed portion 120v. The light sensing device 140 overlaps the display panel 110 and the first cutout 120v in a plan view. The light sensing device 140 is located in the first hollow portion 120v in a top view, and the light sensing device 140 is disposed in the first hollow portion 120v (see fig. 16). As shown in fig. 16, the light sensing device 140 passes through the first hollowed-out portion 120v, but not limited thereto. The display panel 110 has a light sensing portion 110s corresponding to the light sensing device 140 (i.e., the light sensing portion 110s of the display panel 110 overlaps the light sensing device 140 in the direction Z), and the light sensing portion 110s of the display panel 110 is located between the light sensing device 140 and the cover 130.
Under this design, when the light sensing device 140 performs light sensing, the external light can be received by the light sensing device 140 without passing through the first peep-proof structure 120, so that the light sensing device 140 can receive the external light with stronger light intensity, thereby improving the shooting effect and the sensing effect of the light sensing device 140.
In some embodiments, the light sensing portion 110s may be in a transparent state, so that the light sensing device 140 receives external light, but not limited thereto.
In some embodiments, the light sensing portion 110s of the display panel 110 can adjust its transparency (light transmittance) according to the requirement. For example, when the light sensing device 140 is activated (e.g. the light sensing device 140 is sensing), the light sensing portion 110s of the display panel 110 may be transparent, so that the light sensing device 140 receives external light with high light intensity; when the light sensing device 140 is turned off (e.g., the light sensing device 140 is not sensing), the light sensing portion 110s of the display panel 110 may be in an atomized state or an opaque state to shield the light sensing device 140 (e.g., the photographing lens cannot take an image), but not limited thereto.
In the display panel 110, the structure in the light sensing part 110s may be the same or different from that of the other parts. For example, the display medium layer (such as a liquid crystal layer) of the display panel 110 is disposed in the light sensing portion 110s and other portions (such as the display area 110D and the partial peripheral area 110P) of the display panel 110 (i.e., the structure of the display medium layer in the light sensing portion 110s is the same as that of the display medium layer in other portions of the display panel 110), and the display medium layer (or referred to as the light sensing portion medium layer) in the light sensing portion 110s of the display panel 110 is constantly in a transparent state, so that the light sensing device 140 receives the external light, but is not limited thereto.
In some embodiments, as shown in fig. 17, the photo-sensing portion 110s has a first electrode 414a, a second electrode 414b and a photo-sensing portion dielectric layer 416, and is disposed between the first substrate 112 and the second substrate 118, wherein an electrical signal can be applied to the first electrode 414a and the second electrode 414b, respectively, to adjust the transparency of the photo-sensing portion dielectric layer 416. For example, the photo-sensing portion dielectric layer 416 may be disposed between the first electrode 414a and the second electrode 414b in the direction Z, but is not limited thereto. For example, the first electrode 414a and the second electrode 414b may include transparent conductive materials (such as indium tin oxide or other conductive materials with high transmittance), but are not limited thereto.
The material of the photo sensor dielectric layer 416 can be designed according to the requirements. In some embodiments, the photo-sensing portion dielectric layer 416 may comprise any suitable liquid crystal material. For example, the photo-sensing portion dielectric layer 416 may include polymer dispersed liquid crystal (polymer dispersed liquid crystal, PDLC) and polymer network liquid crystal (polymer network liquid crystal, PNLC), other suitable materials, or combinations thereof. In this case, when the first electrode 414a and/or the second electrode 414b are floating, the photo-sensing portion dielectric layer 416 is in a scattering state, and the photo-sensing portion dielectric layer 416 may have low transparency or be in an atomized state; when a voltage difference greater than zero exists between the first electrode 414a and the second electrode 414b, the photo-sensing portion dielectric layer 416 is transparent, so that the photo-sensing device 140 can receive the external light with high light intensity.
In some embodiments, the photo-sensing portion dielectric layer 416 may include an electrochromic material (electrochromic material). In this case, when a voltage difference exists between the first electrode 414a and the second electrode 414b, the photo-sensing portion dielectric layer 416 may have a color with low transparency, such that the photo-sensing portion dielectric layer 416 may shield the photo-sensing device 140; when another voltage difference exists between the first electrode 414a and the second electrode 414b, the photo-sensing portion dielectric layer 416 may have high transparency, so that the photo-sensing device 140 may receive external light.
Referring to fig. 18, fig. 18 is a schematic perspective view of a display panel, a first peep-proof structure and a light sensing device according to a variation of the fourth embodiment of the invention. As shown in fig. 18, the present modified embodiment differs from the fourth embodiment in the shape of the hollowed-out portion. In the display device 400A shown in fig. 18, the first hollowed-out portion 120v of the first peep-proof structure 120 is perforated, and will not be described herein.

For brevity, fig. 21 omits to show the detailed structures (such as the first substrate 112, the second substrate 118, the circuit element layer 114 and the display medium layer 116) in the display panel 110, and the related description of the display panel 110 of the present embodiment may refer to the first embodiment. As shown in fig. 19 to 21, the difference between the present embodiment and fig. 12 is the design of the display panel 110 of the present embodiment. In the display device 500, the display panel 110 does not have a hollowed portion, and the first peep-proof structure 120 and the second peep-proof structure 320 have a first hollowed portion 120v and a third hollowed portion 320v, respectively. The light sensing device 140 overlaps the display panel 110, the first hollowed-out portion 120v of the first peep-proof structure 120, and the third hollowed-out portion 320v of the second peep-proof structure 320 in a top view. The photo-sensing device 140 is located in the first hollowed portion 120v and the third hollowed portion 320v in a top view, and the photo-sensing device 140 is disposed in the first hollowed portion 120v and the third hollowed portion 320v (as shown in fig. 21). Specifically, in the present embodiment, the first peep-preventing structure 120 and the second peep-preventing structure 320 are stacked to form the peep-preventing module PM, the first hollowed-out portion 120v and the third hollowed-out portion 320v are stacked to each other and connected to each other to form the hollowed-out area TH5 penetrating through the peep-preventing module PM, the light sensing device 140 overlaps the hollowed-out area TH5 in a top view, and the light sensing device 140 is disposed in the hollowed-out area TH5 (as shown in fig. 21). The display panel 110 has a light sensing portion 110s corresponding to the light sensing device 140 (i.e., the light sensing portion 110s of the display panel 110 overlaps the light sensing device 140 in the direction Z), and the light sensing portion 110s of the display panel 110 is located between the light sensing device 140 and the cover 130. The light sensing portion 110s of the present embodiment is similar to the light sensing portion 110s of the fourth embodiment, and will not be described herein.
In addition, in the modified embodiment of the present embodiment, the shapes of the first hollowed-out portion 120v of the first peep-proof structure 120 and the third hollowed-out portion 320v of the second peep-proof structure 320 may be similar to the perforations of fig. 5 and 7, and will not be repeated here.
It should be noted that in the first to fifth embodiments and the modified embodiments, the display device may further include one or more polarizers (not shown) overlapping the display panel and the peep-proof structure, and at least one polarizer has a hollowed-out portion. The hollowed-out portion of the polarizer overlaps the hollowed-out portion of the peep-preventing structure and the hollowed-out portion of the display panel in a top view (e.g., overlaps the first hollowed-out portion 120v of the first peep-preventing structure 120 and the second hollowed-out portion 110v of the display panel 110 in the first and second embodiments, or overlaps the first hollowed-out portion 120v of the first peep-preventing structure 120, the second hollowed-out portion 110v of the display panel 110 and the third hollowed-out portion 320v of the second peep-preventing structure 320 in the third and variant embodiments thereof), or overlaps the hollowed-out portion of the polarizer overlaps the hollowed-out portion of the peep-preventing structure (e.g., overlaps the first hollowed-out portion 120v of the first peep-preventing structure 120 in the fourth embodiment, or overlaps the first hollowed-out portion 120v of the second peep-preventing structure 320v of the first peep-preventing structure 120 in the fifth embodiment).
Referring to fig. 22 and 23, fig. 22 is a schematic cross-sectional view of a display device with a collimation type backlight unit in a first state, and fig. 23 is a schematic cross-sectional view of a display device with a collimation type backlight unit in a second state. The backlight module 150 of the present invention may be a collimated backlight module to emit collimated light. The following description will take the backlight module 150 of the display device 100 of the first embodiment or the display device 400 of the fourth embodiment as an example of a collimation type backlight module, but the collimation type backlight module can be applied to any embodiment of the display device with a backlight module of the present invention, and the description thereof will be omitted. Next, the first light control medium layer 126 of the first light control structure 120 of the display device 100 of the first embodiment or the display device 400 of the fourth embodiment includes a polymer liquid crystal layer (e.g., including a polymer dispersed liquid crystal and a polymer network-type liquid crystal). As shown in fig. 22, the collimated backlight (e.g., collimated light Lc) is incident into the first peep-preventing structure 120, and when the first peep-preventing structure 120 is in the first state (sharing state), the polymer liquid crystal layer of the first peep-preventing structure 120 is in a scattering state, so that the first peep-preventing structure 120 can diffuse the collimated light Lc to make the light emitted from the first peep-preventing structure 120 be the scattered light Ld, so that the display device 100 or 400 has a first viewing angle range VA1 (e.g., fig. 4, the user can view the display device 100 or 400 in the first viewing angle range VA 1). As shown in fig. 23, the collimated backlight (e.g., collimated light Lc) is incident into the first peep-preventing structure 120, and when the polymer liquid crystal layer of the first peep-preventing structure 120 is in the second state (peep-preventing state or privacy state), the polymer liquid crystal layer of the first peep-preventing structure 120 is in the transparent state, so that the light passing through the first peep-preventing structure 120 is still collimated light Lc or nearly collimated light Lc, so that the display device 400 has the second viewing angle range VA2 (e.g., fig. 4, the user can view the display device 100 or 400 in the second viewing angle range VA 2). In the present invention, the first viewing angle range VA1 is greater than the second viewing angle range VA2.
In summary, since the light sensing device of the present invention is disposed in the hollowed portion, the light sensing device can receive the external light with strong light intensity, so as to improve the photographing effect and the sensing effect of the light sensing device.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
