Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
In order to solve the technical problem that in the prior art, a display having an off-screen camera module has a display screen with a display area corresponding to the off-screen camera module and has a poor display effect, an embodiment of the invention provides a display panel. The display panel includes a light emitting substrate. The light-emitting substrate is provided with a first side and a second side which are opposite, a main display area and an auxiliary display area adjacent to the main display area are defined on the first side of the light-emitting substrate, and an orthographic projection area of the auxiliary display area on the surface of the second side of the light-emitting substrate is an area facing the camera module; the main display area and the auxiliary display area are respectively provided with a plurality of sub-pixels in an array mode, and the distribution density of the sub-pixels in the main display area is larger than that of the sub-pixels in the auxiliary display area. The display panel also includes a lenticular layer. The lens layer is arranged in the auxiliary display area of the light-emitting substrate, and is also arranged on a propagation path of a light beam output by the sub-pixel and used for amplifying the imaging of the sub-pixel in the auxiliary display area. As described in detail below.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a display panel according to a first embodiment of the invention, and fig. 2 is a schematic sectional structural diagram of the display panel shown in fig. 1 in a direction a-a. The lens array is omitted in fig. 1.
In one embodiment, the display panel 1 includes a light emitting substrate 11. The light-emitting substrate 11 is capable of light-emitting display as the name implies, and mainly realizes the function of light-emitting display of the display panel 1. The light-emitting substrate 11 is a set of functional film layers that participate in realizing the light-emitting display function of the display panel 1, and includes, for example, a light-emitting device layer, an array layer, and the like, which will be described in detail below.
Specifically, the light emitting substrate 11 has a first side 111 and a second side 112 opposite to each other. The first side 111 of the light-emitting substrate 11 defines a main display area 113 and a sub-display area 114 adjacent to the main display area 113, and an orthographic projection area of the sub-display area 114 on the surface of the second side 112 of the light-emitting substrate 11 is an area facing the camera module. As shown in fig. 2, after the display panel 1 of the present embodiment is matched with the camera module 2, the camera module 2 faces the orthographic projection area of the sub-display area 114 on the surface of the second side 112 of the light-emitting substrate 11. The display device using the display panel 1 of the embodiment also adopts the design of the camera module under the screen, so that the display panel 1 of the embodiment is allowed to design a higher screen occupation ratio, and the requirement of a user on the screen occupation ratio can be better met.
In addition, a plurality of sub-pixels 115 are arranged in an array in the main display area 113 and the sub-display area 114, respectively. The sub-pixels 115 in the main display area 113 and the sub-display area 114 may include R (Red ), G (Green ), B (Blue, Blue), and the like sub-pixels 115. In order to make the portion of the light-emitting substrate 11 located in the sub-display region 114 have sufficient light transmittance to ensure the imaging effect of the camera module, the distribution density of the sub-pixels 115 in the main display region 113 is greater than the distribution density of the sub-pixels 115 in the sub-display region 114 in this embodiment, as shown in fig. 1. The distribution density of the sub-pixels 115 is defined as the number of sub-pixels 115 included in a unit area of the display area. In this way, the sub-pixels 115 in the sub-display region 114 have a low distribution density, and the sub-pixels 115 block light, so that the sub-pixels 115 in the sub-display region 114 block light less, which means that the light transmittance of the sub-display region 114 is high, thereby ensuring the imaging effect of the camera module.
In an embodiment, the lens layer is a lens array 12, the lens array 12 is disposed in the sub-display region 114 of the light emitting substrate 11, and the lens array 12 is further disposed on a propagation path of the light beam output by the sub-pixel 115 for enlarging an image of the sub-pixel 115 in the sub-display region 114.
Specifically, as shown in fig. 2, the lens array 12 is disposed in the sub-display region 114 of the light emitting substrate 11. The lens array 12 includes a plurality of lenses 121 arranged in an array, and the lenses 121 are disposed on the propagation path of the light beams output by the sub-pixels 115, and are used for enlarging the image of the sub-pixels 115 in the sub-display region 114. The image of the sub-pixel 115 in the sub-display region 114 is magnified by the lens 121, so that the graininess of the display screen of the sub-display region 114 is weakened, and the display effect of the sub-display region 114 can be improved. Fig. 3 shows a case where the image of the sub-pixel 115 in the sub-display region 114 is magnified by the lens 121, and the magnified image of the sub-pixel 115 is 115'.
It should be noted that one lens 121 may correspond to a plurality of sub-pixels 115 in the sub-display region 114 to simultaneously enlarge the image formed by the plurality of sub-pixels 115. However, since the sub-pixels 115 closer to the center of the lens 121 have better image magnification effect, and the sub-pixels 115 away from the center of the lens 121 have poorer image magnification effect, the problem of poor uniformity of the image magnification effect of each sub-pixel 115 is easily caused. Therefore, in the present embodiment, the lenses 121 and the sub-pixels 115 in the sub-display region 114 are preferably arranged in a one-to-one correspondence manner, that is, one lens 121 is arranged only on the propagation path of the light beam output by one sub-pixel 115, and the center of the orthographic projection of the sub-pixel 115 in the sub-display region 114 on the surface of the first side 111 of the light-emitting substrate 11 overlaps with the center of the orthographic projection of the corresponding lens 121 on the surface of the light-emitting substrate 11 on the first side 111, that is, the center of the sub-pixel 115 in the sub-display region 114 is arranged corresponding to the center of the lens 121 (which will be described in detail later), which is beneficial to ensuring the uniformity of the imaging magnification effect of each sub-pixel 115, that is beneficial to improving the imaging magnification effect of the sub-pixel 115, and further beneficial.
It is understood that in other embodiments of the present invention, the lens layer may not adopt the design of the lens array 12, and may be a whole layer structure, i.e. the lens layer itself is a lens, which plays a role of magnifying the image of the sub-pixel 115, and is not limited herein.
In addition to the above-mentioned way of setting the lens 121 and the sub-pixel 115 in a one-to-one correspondence, the imaging magnification effect of the sub-pixel 115 can be improved by adjusting the lens 121, and the imaging magnification of the sub-pixel 115 can be directly improvedAnd (5) effect. Specifically, the lens 121 of the present embodiment is preferably a convex lens 121 or the like, which has a function of magnifying imaging. The cross-section of the lens 121 along its main optical axis is an ellipse, the minor axis length of which is defined as 2R, the refractive index of the lens 121 is n, and the focal length of the lens 121 is F, as shown in fig. 6. Wherein,
by the above manner, the imaging of the sub-pixel 115 magnified by the lens 121 can achieve a predetermined effect, and the imaging of the sub-pixel 115 magnified can be prevented from being too large or too small.
Since the refractive index of the lens 121 is constant once the material of the lens 121 is selected, the present embodiment allows the focal length of the lens 121 to be adjusted by adjusting the length of the short axis of the cross section of the lens 121 along the central axis thereof, so that the lens 121 magnifies the image of the sub-pixel 115 to achieve a predetermined effect. Moreover, the focal length of the lens 121 can be adjusted according to the specific position of the lens 121 on the light-emitting substrate 11, so that the lens 121 magnifies the image of the sub-pixel 115 to achieve a predetermined effect.
In an embodiment, in order to further enable a portion of the light emitting substrate 11 located in the sub-display region 114 to have sufficient light transmittance so as to further ensure an imaging effect of the camera module, in the embodiment, a pixel opening size corresponding to each sub-pixel 115 in the main display region 113 is greater than or equal to a pixel opening size corresponding to each sub-pixel 115 in the sub-display region 114. Preferably, the pixel opening size of each sub-pixel 115 in the main display area 113 is larger than the pixel opening size of each sub-pixel 115 in the sub-display area 114, as shown in fig. 1. That is to say, the pixel opening size corresponding to each sub-pixel 115 in the sub-display region 114 is smaller, that is, the size of a single sub-pixel 115 is smaller, so that the shielding of the sub-pixel 115 in the sub-display region 114 to light is further reduced, which means that the light transmittance of the sub-display region 114 is further increased, and further contributes to ensuring the imaging effect of the camera module. It is known that the pixel opening size is the light emitting area of each pixel.
In an embodiment, the arrangement of the sub-pixels 115 in the main display area 113 may or may not be the same as the arrangement of the sub-pixels 115 in the sub-display area 114. Preferably, the arrangement of the sub-pixels 115 in the main display area 113 is the same as the arrangement of the sub-pixels 115 in the sub-display area 114, which is beneficial to simplify the pixel arrangement design of the display panel 1 and simplify the corresponding mask design.
Referring to fig. 4 and 5, fig. 4 is a schematic structural diagram of a display panel according to a second embodiment of the present invention, and fig. 5 is a schematic structural diagram of a display panel according to a third embodiment of the present invention. Fig. 4 and 5 show the structure in the sub display region 114 of the display panel 1.
In one embodiment, the light emitting substrate 11 includes a stacked light emitting device layer 116 and an array layer 117. The light emitting device layer 116 integrates a light emitting device functioning as a light emitting display. Specifically, the light emitting device layer 116 includes an anode layer 1161, a light emitting layer 1162, and a cathode layer 1163, which are sequentially stacked in a direction away from the array layer 117. The light emitting layer 1162 includes a plurality of light emitting units 1164 arranged at intervals and in an array, the light emitting units 1164 perform a light emitting display function, and one light emitting unit 1164 corresponds to one sub-pixel described above. The lenses 121 described above are disposed in one-to-one correspondence with the sub-pixels, and one lens 121 is disposed only on the propagation path of the light beam output by one sub-pixel, specifically, the lens 121 is disposed in one-to-one correspondence with the light emitting unit 1164, that is, one lens 121 is disposed only on the propagation path of the light beam output by one light emitting unit 1164. The sub-pixels described above are disposed corresponding to the center of the lens 121, and in particular, the light emitting unit 1164 is disposed corresponding to the center of the lens 121. The array layer 117 is integrated with a driving circuit for driving the light emitting device layer 116 to emit light for display, and mainly includes a Thin Film Transistor (TFT) array and corresponding circuit structures, such as a gate, a source, a drain, an interlayer dielectric layer, and a buffer layer of the TFT.
The first side 111 of the light-emitting substrate 11 is a side of the cathode layer 1163 away from the light-emitting layer 1162, that is, the display panel 1 of this embodiment is in a top-emission display form, and the lens array 12 is disposed on a side of the cathode layer 1163 away from the light-emitting layer 1162, so as to implement an effect of the lens 121 in the lens array 12 to magnify the image of the sub-pixel 115, as shown in fig. 4; or the first side 111 of the light emitting substrate 11 is a side of the array layer 117 facing away from the anode layer 1161, that is, the display panel 1 of this embodiment is in a bottom emission display form, and the lens array 12 is disposed on a side of the array layer 117 facing away from the anode layer 1161, so as to implement an effect of the lens 121 in the lens array 12 to magnify the image of the sub-pixel 115, as shown in fig. 5.
The specific arrangement of the lens array 12 in the display panel 1 of the top emission or bottom emission display form according to the embodiment of the present invention is explained below.
In an embodiment, the light emitting direction of the display panel 1 is a direction from the light emitting layer 1162 to the cathode layer 1163, and the lens array 12 is disposed on a side of the cathode layer 1163 away from the light emitting layer 1162.
Please continue to refer to fig. 1, fig. 2 and fig. 4. In particular, the display panel 1 is in a top-emission display form, i.e. the first side 111 of the light-emitting substrate 11 is the side of the cathode layer 1163 facing away from the light-emitting layer 1162. In order to support the display form of top emission of the display panel 1, a portion of the anode layer 1161 corresponding to the light emitting unit 1164 is opaque, and the remaining portion is transparent, and the cathode layer 1163 is transparent, so that light output from the light emitting unit 1164 to the cathode layer 1163 is output through the cathode layer 1163, and light output to the anode layer 1161 is reflected back to the cathode layer 1163 for output, that is, the display panel 1 is in the display form of top emission. The lens array 12 is disposed on a side of the cathode layer 1163 away from the light emitting layer 1162, so that the light beam output by the cathode layer 1163 can pass through the lens array 12 to realize enlarged imaging of the sub-pixels 115.
Further, the light emitting substrate 11 further includes an encapsulation layer 118, and the encapsulation layer 118 is disposed between the cathode layer 1163 and the lens array 12 or disposed on a side of the lens array 12 away from the cathode layer 1163. As shown in fig. 4, the encapsulation layer 118 is preferably disposed between the cathode layer 1163 and the lens array 12. That is, in the embodiment, after the light emitting substrate 11 is packaged, the lens array 12 is prepared, so that the influence of the lens array 12 on the packaging process can be avoided, and the influence of the lens array 12 on the original process of the display panel 1 can be reduced as much as possible. The Encapsulation layer 118 may be a Thin-Film Encapsulation (TFE), and is not limited herein.
Of course, in other embodiments of the present invention, the lens array 12 may be prepared after the TP (Touch Panel) module and the polarizer module on the light-emitting substrate 11 are prepared, so as to reduce the influence of the lens array 12 on the original manufacturing process of the display Panel 1 to the maximum extent.
It should be noted that, when the lens array 12 is disposed at different positions of the light-emitting substrate 11, it may be necessary to adjust specifications of the lenses 121 in the lens array 12, such as the short-axis length of the cross section of the lenses 121 along the central axis thereof, to adjust the focal length of the lenses 121 in the lens array 12, and so on, so as to ensure that the sub-pixels 115 have good magnifying imaging effect.
In an alternative embodiment, the light emitting direction of the display panel 1 is the direction from the light emitting layer 1162 to the anode layer 1161, and the lens array 12 is disposed on a side of the anode layer 1161 away from the light emitting layer 1162.
Please continue to refer to fig. 1, fig. 2 and fig. 5. In particular, the display panel 1 is in a bottom emission display form, i.e. the first side 111 of the light emitting substrate 11 is the side of the array layer 117 facing away from the anode layer 1161. In order to support the display form of bottom emission of the display panel 1, the cathode layer 1163 is partially opaque and the rest is transparent corresponding to the light emitting unit 1164, and the anode layer 1161 and the array layer 117 are transparent, so that the light output from the light emitting unit 1164 to the anode layer 1161 is output through the anode layer 1161 and the array layer 117, and the light output to the cathode layer 1163 is reflected back to the anode layer 1161 for output, that is, the display panel 1 is in the display form of bottom emission. The lens array 12 is disposed on a side of the array layer 117 facing away from the anode layer 1161, so that light beams output through the anode layer 1161 and the array layer 117 can pass through the lens array 12 to realize enlarged imaging of the sub-pixels 115.
Part of the cathode layer 1163 corresponding to the light emitting unit 1164 is opaque and the rest is transparent, specifically, the cathode layer 1163 may be disposed as a whole layer, but part of the cathode layer 1163 corresponding to the light emitting unit 1164 is opaque and the rest is transparent; or the cathode layer 1163 is designed similarly to the anode layer 1161, that is, the cathode layer 1163 is also designed to be a block structure, and the block cathodes and the light emitting units 1164 are in one-to-one correspondence and are arranged to be light-tight, and are used for reflecting light output by the light emitting units 1164 to the cathode layer 1161. While the areas between the block-shaped cathodes are light-transmissive (i.e., no opaque cathodes are provided), i.e., the remainder of the cathode layer 1161 is light-transmissive. In this way, ambient light is allowed to enter the camera module (at this time, the camera module 2 is located on the side of the cathode layer 1163 away from the light emitting layer 1162, as shown in fig. 5), and imaging of the camera module is achieved.
Further, the side of the array layer 117 facing away from the anode layer 1161 on the light-emitting substrate 11 is usually provided with a light-transmissive substrate 119 to support the bottom emission display mode of the display panel 1, as shown in fig. 5. Therefore, the lens array 12 is preferably disposed on a side of the substrate 119 facing away from the array layer 117, so as to reduce the influence of the lens array 12 on the original manufacturing process of the display panel 1. Also, the transparent anode layer 1161, the array layer 117 and the substrate 119 are also for allowing ambient light to enter the camera module.
It should be noted that, when the off-screen camera module operates and collects an image, the sub-display region 114 of the light-emitting substrate 11 may be in a light-emitting display state or in a non-light-emitting display state. Wherein, when the camera module works under the screen, when gathering the image, the vice display area 114 of luminescent substrate 11 is in the state of not luminous demonstration, and each functional film layer of the vice display area 114 of luminescent substrate 11 under this condition also can be the design that adopts high luminousness, for example is the transparence to guarantee the formation of image effect of camera module.
In summary, in the display panel provided by the present invention, the orthographic projection area of the sub-display area on the surface of the light-emitting substrate on the second side is an area facing the camera module, and the distribution density of the sub-pixels in the main display area is greater than the distribution density of the sub-pixels in the sub-display area. The distribution density of the sub-pixels in the auxiliary display area is small, so that the light transmittance of the auxiliary display area is improved, and the imaging effect of the camera module is ensured. And the sub-display area of the light-emitting substrate is also provided with a lens layer, wherein the lens layer is arranged on a propagation path of light beams output by the sub-pixels and is used for amplifying the imaging of the sub-pixels in the sub-display area. The imaging of the sub-pixels in the sub-display area is enlarged by the lens, so that the graininess of the display picture of the sub-display area is weakened, and the display effect of the sub-display area can be improved.
