Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Referring to fig. 1, a schematic structural diagram of an electronic device in the related art is shown, and as shown in fig. 1, the electronic device includes a TP101, a sensor assembly 102 and a front housing 103 which are located below the TP101 in parallel, and a display screen 104 which is located above the TP101 and the front housing 103. Optionally, the sensor assembly 102 is located on an FPC (Flexible Printed Circuit) 105, and a sealing sleeve 106 is provided outside the sensor assembly 102.

Since the width of the top bezel of the TP101 is equal to the lateral (i.e., the direction pointing to the top of the terminal) spacing from the top of the display 104 to the top of the TP101, and the top of the front housing 103 is located between the sensor assembly 102 and the display screen 104 in fig. 1, the width of the top bezel of the TP101 in fig. 1 is equal to the sum of the width of the sensor 102, the first spacing between the sensor 102 and the front housing 103, the width of the top of the front housing 103, and the second spacing between the front housing 103 and the display screen 104. When the width of the TP101 is fixed, the larger the width of the top frame of the TP101 is, the smaller the width of the transparent region corresponding to the display screen 104 in the TP101 is, which also results in a lower screen occupation ratio of the display screen 104.

In one embodiment, the spacing between the sensor assembly 102 and the TP101 is approximately within 0.5mm (as indicated by dimension 1 in FIG. 1); the edge of the sensor assembly 102 is a measurement reference point and is spaced approximately 1.5-3.5mm from the top of the display screen 104 (as indicated by dimension 2 in FIG. 1).

In this embodiment, the sensor assembly 102 may be disposed below the front housing 103, such that the top of the front housing 103 is not located between the sensor assembly 102 and the display screen 104, so as to achieve the purpose of reducing the width of the top frame of the TP101, as described in the following embodiments.

Fig. 2 is a schematic structural diagram of an electronic device according to an exemplary embodiment, where the electronic device sequentially includes, in a preset direction, as shown in fig. 2: a rear housing 201, a front housing 202, and a display assembly comprising a display screen 203 and a TP 204; the electronic device further includes: the sensor assembly 205 is positioned in the accommodating cavity formed by the rear shell 201 and close to the top of the rear shell 201; the preset direction refers to a direction from the back of the electronic device to the front of the electronic device.

The display 203 is provided with a gap 212, the top frame of the TP204 is provided with a first opening 213, the first opening 213 is opposite to the gap 212, and the first opening 213 and the gap 212 form a light path for light entering and exiting the sensor assembly 205.

When the sensor assembly 205 comprises a light sensor, there is incident light entering the light sensor from outside the electronic device, and this incident light then enters the light sensor through the first aperture 213 and the slot 212 in sequence. The light sensor has a light sensing function.

When the sensor assembly 205 includes a distance sensor, there is an outgoing light ray from the distance sensor to the electronic device and an incoming light ray from outside the electronic device to the distance sensor, and at this time, the outgoing light ray exits the electronic device through the slit 212 and the first opening 213 in order, and the incoming light ray enters the distance sensor through the first opening 213 and the slit 212 in order. The distance sensor has a distance sensing function.

The electronic device may be a smart phone, a tablet computer, a notebook computer, a handheld device, a wearable device, a vehicle-mounted device, and the like, which is not limited in this embodiment.

In summary, according to the electronic device provided by the present disclosure, the sensor assembly is located in the accommodating cavity formed by the rear shell, and the front shell is located on the rear shell in the preset direction, so that the sensor assembly is located below the front shell, and thus, the top of the front shell is not located between the sensor assembly and the display screen. And because the width of the top frame of the TP is equal to the transverse (i.e. the direction pointing to the top of the terminal) distance from the top of the display screen to the top of the TP, the width of the top frame of the TP when the top of the front shell is not between the sensor assembly and the display screen is smaller than the width of the top frame of the TP when the top of the front shell is between the sensor assembly and the display screen, thereby improving the screen occupation ratio of the display screen by reducing the width of the top frame of the TP.

As shown in fig. 2, the electronic device sequentially includes, in a preset direction: a back cover 201, a front cover 202, and a display assembly comprising a display screen 203 and a TP 204; the electronic device further includes: and the sensor assembly 205 is positioned in the accommodating cavity formed by the rear shell 201 and is close to the top of the rear shell 201.

The sensor assembly 205 is located within the receiving cavity formed by the rear housing 201, and the display screen 203 is located between the front housing 202 and the TP 204.

In this embodiment, the sensor assembly 205 may include a light sensor, a distance sensor, a light sensor and a distance sensor, and an integrated sensor having a light sensing function and a distance sensing function, which is not limited in this embodiment.

In this embodiment, the display assembly includes a display screen 203 and a TP 204. In one possible implementation, the front shell 202 is connected to the sides of the display screen 203 and the TP204, respectively. In another possible implementation manner, the front shell 202 is connected to a side surface of the TP204, and at this time, the front shell 202 and the TP204 cooperate to form a receiving cavity in which the display screen 203 is located.

The TP204 is configured to sense a touch operation of a user, control the electronic device through the touch operation, and the display screen 203 is configured to display information. In this embodiment, only the TP204 and the display 203 are described as an example, in actual implementation, the TP204 may be replaced by a protection panel without a touch sensing function, or the TP204 is further provided with a protection panel, where the protection panel serves to protect the display 203 so as to increase the service life of the display 203.

Optionally, the display screen 203 in this embodiment is a full-screen. A full screen is a display screen with a screen fraction close to 100%. That is, the screen occupancy of the display screen 203 is close to 100%.

The Display screen 203 in this embodiment may be an LCD (Liquid Crystal Display) or an OLED (Organic Light-Emitting Diode) Display screen. Since LCD and OLED display panels have different structures, the structure of an electronic device having the above display panel will be described below.

1) The display 203 is an LCD.

Because the LCD is provided with a backlight, a luminous layer of the LCD is not transparent and cannot transmit light; the sensor assembly 205 needs to transmit light during normal use, so the sensor assembly 205 and the LCD need to be staggered in the direction perpendicular to the LCD and cannot be completely overlapped.

Since the sensor assembly 205 may include at least one of a distance sensor and a light sensor, and the distance sensor requires that light coming in and out is not blocked by devices in the electronic device, and the light sensor requires that light coming in is not blocked by devices in the electronic device made of opaque materials, the sensor assembly 205 including the distance sensor and the light sensor is described as an example.

In a first implementation, the distance sensor partially overlaps the LCD in a first direction perpendicular to the LCD, and the light sensor partially overlaps the LCD in the first direction; at this time, the slit is formed by the top of the front case 202 being fitted with the top of the LCD.

In this embodiment, the sensor assembly 205 with a smaller package size may be selected, and the sensor assembly 205 may be arranged on the top of the electronic device in a transverse manner, where the long side of the sensor assembly 205 is parallel to the short side of the electronic device.

The lateral spacing between the right side edge of sensor assembly 205 and the top of the LCD may be a small positive number (where sensor assembly 205 does not overlap the LCD, as shown by dimension 1 in fig. 2), or the lateral spacing between the right side edge of sensor assembly 205 and the top of the LCD may be a negative number (where sensor assembly 205 partially overlaps the LCD) to further reduce the width of the top bezel of TP 204. It should be noted that when the LCD partially overlaps the sensor assembly 205, the LCD does not block light from entering or exiting the sensor assembly 205.

In this embodiment, the gap 212 is formed by the top of the front housing 202 mating with the top of the LCD. It should be noted that the width of the gap 212 in this embodiment may not include the mounting gap reserved for the LCD, and in this case, the width of the gap 212 is equal to the width of the first opening 213 of the TP204, as shown by the dimension 2 in fig. 2. At this time, the width of the gap 212 may be within a predetermined interval, which is not limited in this embodiment. In one possible implementation, the predetermined interval is [0.4, 1.2] mm.

When the width and the length of the slit 212 are both small, the slit 212 has a good light transmission effect, and at this time, the light guide pillar 206 may not be disposed in the slit 212, please refer to fig. 3. That is, when the width of the slot 212 is less than the first threshold and the separation distance (shown as dimension 3 in fig. 2) between the sensor assembly 205 and the TP204 in the first direction perpendicular to the display screen 203 is less than the third threshold, the light guide bar 206 is not disposed in the slot 212. The first threshold and the third threshold may be empirical values or numerical values calculated by a predetermined algorithm, and the embodiment is not limited. In one possible implementation, the first threshold is 0.6mm and the third threshold is 2 mm.

When the width and the length of the slit 212 are both large, the slit 212 has a poor light transmission effect, and at this time, the light guide pillar 206 may be disposed in the slit 212 to improve the light path, please refer to fig. 2. That is, when the width of the gap 212 is greater than the first threshold and the distance between the sensor assembly 205 and the TP204 in the first direction perpendicular to the display screen 203 is less than the second threshold, the light guide bar 206 is disposed in the gap 212. The second threshold may be an empirical value or a numerical value calculated by a predetermined algorithm, and the embodiment is not limited. In one possible implementation, the second threshold is 3 mm.

When the light guide bar 206 is disposed in the slot 212, the center of the light guide bar 206 in the second direction is aligned with the at least two third openings for transmitting and receiving light in the sensor assembly 205, and the second direction is the arrangement direction of the at least two third openings. In a possible implementation, the second direction is a lateral direction, i.e. a direction parallel to a short side of the electronic device.

Optionally, the light guide pillar 206 may be made of PMMA (Poly Methyl Methacrylate) or other materials, and the light guide pillar 206 may have a certain dust-proof function.

Optionally, a sealing sleeve 207 is provided outside the sensor assembly 205. The material of the sealing sleeve 207 may be TPU (Thermoplastic polyurethane elastomer) or other materials. Wherein, the seal sleeve 207 and the sensor assembly 205 can be matched with each other in a zero way or have an interference of 0.05mm between the transverse direction and the longitudinal direction, so as to achieve the effect of sealing and dust prevention. The longitudinal direction refers to a direction parallel to a long side of the electronic apparatus.

Alternatively, the light guide 206 and the sealing sleeve 207 may be formed by two-color injection molding.

Optionally, the light entrance and exit surface in the light guide column 206 is obtained by polishing, which may also be referred to as bright surface treatment, so as to avoid the problem that light is reflected when the light enters or exits uneven light entrance and exit surface, thereby increasing the entrance and exit amount of light. The non-light entrance and exit surface in the light guide column 206 is obtained by shading, or when the non-light entrance and exit surface in the light guide column is not subjected to shading, the top of the display screen is obtained by shading. Wherein, the shading treatment can be black spraying treatment or shading by adding shading material.

Optionally, the outgoing and incoming light rays from the sensor assembly 205 may be optically shielded to avoid interference between the two light rays. Referring to fig. 4, the sensor assembly 205 has a third opening 214 for incoming light and a fourth opening 215 for outgoing light, and the third opening 214 for incoming light and the fourth opening 215 for outgoing light may be separated by a silicone or other soft rubber sleeve.

In a possible implementation manner, a groove 208 is formed in one side of the light guide bar 206 close to the sensor assembly 205, a projection position of the groove 208 on the sensor assembly 205 is located between a third opening 214 for injecting light and a fourth opening 215 for injecting light, and the groove 208 is filled with an opaque material; an intersection 209 of the light exiting through the bottom surface of the groove 208 and the light entering through the bottom surface of the groove 206 is located within TP.

Wherein the width of the groove 208 is greater than 0.6mm and the depth (as shown by dimension 1 in fig. 3) is determined according to the angles of the incident light and the emergent light in the sensor assembly 205. That is, the intersection 209 of the oppositely extending lines of incident light rays in the sensor assembly 205 that intersect the first side and the outgoing light rays in the sensor assembly 205 that intersect the second side lie within the thickness of the TP 204. Wherein the first side is a side of the bottom surface of the groove 208 along a third direction perpendicular to the arrangement direction of the third opening 214 for the incident light and the fourth opening 215 for the outgoing light, and is close to the third opening 214 for the incident light; the second side is the other side of the bottom surface of the groove 208 parallel to the first side. Alternatively, the intersection 209 may be located at an intermediate position within the thickness of the TP 204.

Optionally, the light guide 206 may be fixed in the front case 202, or the light guide 206 may be fixed in the rear case 201.

Alternatively, the sensor assembly 205 may be located on the FPC 210; the FPC210 may be located on a holder 211 in the rear case 201, or the FPC may be located on the rear case 201.

Wherein, the sensor assembly 205 can be pasted on the FPC10, the pasting position of the FPC210 is reinforced by a reinforcing plate and fixed on the bracket 211 or the rear shell 201, and the bracket 211 can be effectively fixed on the rear shell 201. Optionally, the sensor assembly 205 may also need to be pre-assembled for precise positioning in the lateral, longitudinal, and first directions.

Optionally, the FPC210 may be connected and conducted with a main board through a BTB (board To board) or other method, so as To implement the function of the sensor assembly 205.

It should be noted that glue is required between the front shell 202 and the TP204, and the size of the glue can be designed to be between 0.4 mm and 0.5mm, so that the width of the top frame of the TP204 can be less than 2.5 mm.

In a second implementation manner, the distance sensor and the LCD are partially overlapped in a first direction perpendicular to the LCD, the light sensor is located at the top of the electronic device, a second opening is formed in the top of the electronic device, and a light path of light entering and exiting the light sensor is formed by the second opening; at this time, the slit 212 is formed by the top of the front case 202 being fitted with the top of the LCD.

The position relationship between the distance sensor and the LCD is the same as that in the first implementation manner, and is not described herein again.

Optionally, when the light sensor is located at the top of the electronic device, the light sensor may be located in the rear shell 201 of the electronic device, and at this time, a second opening is formed in the rear shell 201, so that light may enter the light sensor through the second opening; or in the front case 202 of the electronic device, where the front case 202 has a second opening, so that light can enter the light sensor through the second opening; the present embodiment is not limited.

In a possible implementation manner, when the light sensor is located at the top of the electronic device, the light guide column is further required to be arranged at the top of the electronic device, so that the incident light emitted from the second opening hole is guided by the light guide column, and the incident light is emitted into the light sensor.

2) The display screen 203 is an OLED display screen.

In a first implementation mode, the distance sensor and the light sensor are all positioned below the OLED display screen; at this point, the aperture 212 is formed by a cut-out of the foam 216 under the OLED display.

Since the light-emitting layer and the glass of the OLED display are made of transparent materials, the distance sensor and the light sensor can achieve corresponding functions through light transmission of the screen by only cutting a cut in the foam 216 below the OLED display, please refer to fig. 5.

In a second implementation manner, the distance sensors are all located below the OLED display screen, the light sensor is located at the top of the electronic device, a second opening is formed in the top of the electronic device, and a light path of light entering and exiting the light sensor is formed by the second opening; at this point, the aperture 212 is formed by a cut-out of the foam 216 under the OLED display.

The position relationship between the distance sensor and the OLED display screen is described in the first implementation manner in fig. 2), and the position relationship between the light sensor and the electronic device is described in the second implementation manner in fig. 1), which are not described herein again.

In a third implementation, the distance sensor partially overlaps the OLED display screen in a first direction perpendicular to the OLED display screen, and the first gap 212 is formed by the top of the front shell 202 and the top of the OLED display screen in a matching manner; the light sensors are all located under the OLED display and the second aperture 212 is formed by a cut-out of the foam 216 under the OLED display.

The position relationship between the distance sensor and the OLED display screen is described in the first implementation manner in 1) and the position relationship between the light sensor and the electronic device is described in the first implementation manner in 2), which is not described herein again.

In a fourth implementation, the distance sensor partially overlaps the OLED display screen in a first direction perpendicular to the OLED display screen, and the gap 212 is formed by the top of the front shell 202 and the top of the OLED display screen in a matching manner; the light sensor is located the top of electronic equipment and the top of electronic equipment is equipped with the second trompil, and the light path of the light of light sensor is gone out and come in to the second trompil formation.

The position relationship between the distance sensor and the OLED display screen is described in the first implementation manner in 1), and the position relationship between the light sensor and the electronic device is described in the second implementation manner in 1), which are not described herein again.

It should be noted that, except for the sensor assembly 205 in fig. 2), other unexplained devices are described in the first implementation manner in fig. 1), and are not described herein again.

In summary, the electronic device provided by the present disclosure, because the sensor assembly is located in the accommodating cavity formed by the rear shell, and the front shell is located on the rear shell in the preset direction, the sensor assembly is located below the front shell, and thus, the top of the front shell is not located between the sensor assembly and the display screen. And because the width of the top frame of the TP is equal to the transverse (i.e. the direction pointing to the top of the terminal) distance from the top of the display screen to the top of the TP, the width of the top frame of the TP when the top of the front shell is not between the sensor assembly and the display screen is smaller than the width of the top frame of the TP when the top of the front shell is between the sensor assembly and the display screen, thereby improving the screen occupation ratio of the display screen by reducing the width of the top frame of the TP.

When the sensor assembly partially or fully overlaps the display screen, the width of the top bezel of the TP may be further reduced, thereby further increasing the screen fraction of the display screen.

The sensor assembly is externally provided with a sealing sleeve, so that the effect of sealing and dust prevention can be realized.

Interference between the outgoing and incoming light rays in the sensor assembly can be avoided by applying a light-blocking treatment to the two light rays.

The light in-out surface in the light guide column is polished, so that the problem that light is reflected when the light is injected or the light with unevenness is injected in or out of the light in-out surface can be avoided, and the light in-out amount is increased.
