Various embodiments of the present application are explained and illustrated below with reference to the drawings.
Referring to fig. 1, a schematic structural diagram of a display panel according to a first embodiment of the present invention includes: the display substrate 11, the display substrate 11 is limited to first area 12 and second area 13, the second area 13 is set up around first area 12.
In an embodiment, the non-display side is provided with a light sensing device at the location of the first area 12 of the display panel. Specifically, a plurality of first pixels 14 are arranged on a surface of the display substrate 11 corresponding to the second region 13, the photosensitive device is arranged in the first region 12 and located on one side of the display substrate 11 away from the first pixels 14, and the photosensitive device can be a camera, so that a display panel of the camera under the screen is formed, and the display panel can realize a real comprehensive screen design.
In an embodiment, a pixel gap is formed between two adjacent first pixels 14, in a specific structure of a display panel, a pixel defining layer is further disposed at the pixel gap, and the display substrate 11 further includes, in addition to the first pixels 14, an anode layer located below the first pixels 14, a planarization layer thin film transistor layer, a cathode layer located above the first pixels 14, a packaging layer, and the like. In an embodiment, the cathode layer, the encapsulation layer, and the like may be disposed on the light-emitting auxiliary layer 18 between the display substrate 11 and the cover plate 16, and the specific structure is not limited. In an embodiment, the light-emitting auxiliary layer 18 is further provided with a touch layer, a polarizer, an optical adhesive, and the like, and it should be noted that, in order not to affect the transmittance of the photosensitive device, the materials with lower transmittance in the light-emitting auxiliary layer 18 are all disposed to avoid the first region 12.
In one embodiment, the first pixel 14 may emit red light, green light, blue light, white light, and the like.
In the present embodiment, the first pixel 14 is not disposed in the first region 12, and specifically, the second region 13 includes a first sub-pixel 131 close to the first region 12 and a second sub-pixel 132 far from the first region 12. The pixel density of the first sub-pixels 131 close to the first region 12 in the second region 13 is greater than the pixel density of the second sub-pixels 132 far from the first region 12. That is, the pixel density distribution of the first sub-pixels 131 close to the first region 12 in the second region 13 is denser, and the pixel density distribution of the second sub-pixels 132 far from the first region 12 in the second region 13 is more dispersed. Specifically, a pixel gap exists between two adjacent first pixels 14, and when the first pixels 14 are densely distributed, the pixel gap is smaller, and when the first pixels 14 are dispersedly distributed, the pixel gap is larger. The pixel gap is small, and the requirement on the process manufacturing is high; the pixel gap is larger, and the manufacturing requirement of the process can be reduced.
In an embodiment, the first area 12 is not provided with first pixels 14, which may be filled with a transparent pixel defining layer or without any pixel defining layer, filled with a completely transparent material such as an encapsulation layer, a transparent optical glue layer.
In the present embodiment, the first area 12 is not provided with the first pixels 14, and when shooting is performed by using the photosensitive device, the film structure of the first area 12 is simple, and light from the outside can reach the photosensitive device on the back surface of the display substrate 11 as much as possible. Since the first pixels 14 are not disposed in the first region 12, light obtained by the photosensitive device is not blocked, so that light transmittance of the photosensitive device can be improved.
In an embodiment, in order not to affect the display effect of the display panel, an optical element 27 is disposed on the display surface side of the display substrate 11, and the optical element 27 is disposed corresponding to the first sub-pixel 131 close to the first area 12, so as to guide the light emitted from the first sub-pixel 131 close to the first area 12 in the second area 13 to the first area 12 of the display surface of the display substrate 11 for emission when the display panel performs display. Even if the first pixel 14 for display is not provided in the first region 12, the first region 12 can emit light at the time of display to perform image display by refracting light with the optical element 27.
In the display panel provided by this embodiment, the first pixel 14 is not disposed in the first region 12, so that the light transmittance of the photosensitive device corresponding to the first region 12 is improved, the density of the first sub-pixel 131 in the second region 13 close to the first region 12 is higher, and the optical element 27 is disposed in the position, so that the optical element 27 guides a part of the light emitted by the first sub-pixel 131 in the position to the first region 12, so that when the display panel displays, the first region 12 also displays; meanwhile, the light emitted from the first sub-pixel 131 at the position can exit from the second region 13, so that although the density of the first sub-pixel 131 at the position close to the first region 12 is higher, the display panel is displayed uniformly as a whole through the adjustment of the light by the optical element 27, and the "first pixels" of the entire display panel viewed by human eyes or machines are still uniformly arranged.
In an embodiment, as shown in fig. 1, the optical element 27 may be disposed separately from the cover 16, as long as the light emitted from the portion of the first sub-pixel 131 in the second region 13 close to the first region 12 can be guided to the display surface of the display panel for displaying. In another embodiment, the optical element 162 may be disposed on the cover 16, and particularly as shown in fig. 2, the cover 16 is disposed on one side of the display surface of the display substrate 11, for example, the cover 16 may be disposed on one side of the display substrate 11 having the first pixel 14, and one side of the cover 16 close to the first pixel 14 is disposed with the optical element 162, and the other side away from the first pixel 14 is used for displaying. Specifically, the cover plate 16 forms the optical element 162 corresponding to a position in the first sub-pixel 131 close to the first region 12 in the second region 13.
In an embodiment, a first plate light-transmitting region 161 corresponding to the first region 12 is further disposed on a side of the cover plate 16 close to the first pixel 14, and a lens region 162 surrounding the first plate light-transmitting region 161 is disposed on the cover plate 16 corresponding to the second region 13 close to the first sub-pixel 131 of the first region 12. Specifically, the lens region 162 is an optical element 162, and the lens region 162 is used for guiding a part of the light emitted from the first sub-pixel 131 close to the first region 12 to the display surface of the first plate light-transmitting region 161 for emitting, so as to perform display in the first region 12. Specifically, the display surface of the first plate light-transmitting area 161 is a position corresponding to the first region 12 on the side of the cover 16 away from the first pixel 14. The position reflects the obtained light emitted by the first pixel 14 through the lens region 162 for display.
The cover plate 16 further includes a second plate light-transmitting region 163 surrounding the lens region 162, the second plate light-transmitting region 163 being disposed corresponding to the second sub-pixel 132 of the second region 13 away from the first region 12. In an embodiment, the second plate light-transmitting region 163 may be partially disposed corresponding to the second sub-pixel 132 of the second region 13 far from the first region 12, and the other portion is disposed corresponding to the first sub-pixel 131 of the second region 13 near the first region 12, as shown in fig. 2.
In one embodiment, the cover 16 has a thickness in the second plate transmissive region 163 that is less than the thickness in the first plate transmissive region 161, and the cover 16 smoothly connects the first plate transmissive region 161 and the second plate transmissive region 163 inside and outside the lens region 162. Specifically, the lens region 162 is located between the first plate light-transmitting region 161 and the second plate light-transmitting region 163, and the lens region 162 may be an inclined surface as shown in fig. 1, 4 and 5, or a curved surface as shown in fig. 2 and 3.
Specifically, taking fig. 2 as an example, the cover 16 is a flat surface on the display surface (the surface far from the first pixel 14) side of the first plate light-transmitting region 161, the lens region 162, and the second plate light-transmitting region 163, and the cover 16 is inclined on the back surface (the surface near the first pixel 14) of the lens region 162 and connects the back surface (the surface near the first pixel 14) of the first plate light-transmitting region 161 of the cover 16 and the back surface (the surface near the first pixel 14) of the second plate light-transmitting region 163.
In one embodiment, the cover 16 is a slanted plane on the back of the lens region 162, and the portion of the first pixels 14 near the first region 12 is uniformly distributed. The cover plate 16 is inclined at an angle of 45 degrees at the back side of the lens region 162 (the side close to the first pixel 14). Of course, other angles are possible such as 30 degrees, 46 degrees, 51 degrees, etc.
In this embodiment, the light emitted from the portion of the first pixels 14 in the second region 13 far from the first region 12 exits from the display surface of the cover 16 corresponding to the second region 13, specifically, the light emitted from the portion of the first pixels 14 in the second region 13 far from the first region 12 exits perpendicularly at the position of the cover 16 corresponding to the second plate light-transmitting region 163. And the light emitted from a part of the first pixels 14 in the second region 13 close to the first region 12 is refracted at the position of the cover 16 corresponding to the lens region 162, so that a part of the light is formed to exit in the first region 12, and the rest of the light exits in the second region 13. Therefore, the display surface of the cover plate 16 can uniformly form the light-emitting rays for displaying, and the light-emitting rays still include red rays, green rays and blue rays; specifically, for example, a red first pixel 14 can form a red light on the cover 16, a green first pixel 14 can form a green light on the cover 16, and a blue first pixel 14 can form a blue light on the cover 16. In order to ensure the display effect, the first pixel density and the second pixel density of the first pixels 14 and the slope angle of the lens region 162 are set reasonably as long as uniform light can be formed on the display surface of the cover 16 for displaying.
In one embodiment, to ensure the display effect of the display panel, the light formed on the display surface of the cover 16 is uniformly distributed.
In another embodiment, the inclination angle of the slanted lens region 162 may not be limited, and the first pixel density of the portion of the first pixel 14 close to the first region 12 may not be limited, as long as the slanted lens region 162 can ensure that the refracted light is uniformly distributed on the display surface of the cover 16 after being refracted.
In the display panel shown in this embodiment, the first pixel 14 is not disposed in the first region 12, so that the light transmittance of the photosensitive device corresponding to the first region 12 is improved, the density of the first pixel 14 in the second region 13 close to the first region 12 is higher, and the optical element 162 for guiding light is disposed in the position, so that the optical element 162 guides a part of the light emitted by the first pixel 14 in the position to the first region 12, so that when the display panel displays, the first region 12 also displays. Specifically, in the display panel of the present embodiment, the optical element 162 is disposed on the cover 16, and the lens region 162 corresponding to the position of the portion of the first pixel 14 of the cover 16 corresponding to the second region 13 close to the first region 12 is the optical element 162, so as to simplify the structure of the display panel.
In one embodiment, the optical element may be glass.
Referring to fig. 3, a schematic structural diagram of a display panel according to a third embodiment of the present invention is shown, and compared with the second embodiment shown in fig. 2, the difference is that the cover plate 16 in this embodiment is a concave arc surface on the back surface of the lens region 162, specifically, the lens region 162 is a concave lens with an arc surface.
Specifically, the arc surface of the lens region 162 shown in this embodiment is an arc surface with the same radius.
As in the first embodiment shown in fig. 2, in this embodiment, the pixel density of the first sub-pixels 131 of the second region 13 close to the first region 12 is greater than the pixel density of the second sub-pixels 132 of the second region 13 far from the first region 12. In this embodiment, the first sub-pixels 131 are uniformly arranged. Specifically, in the display panel shown in this embodiment, the pixel gaps of the first sub-pixels 131 are the same, and the pixel gap of the first sub-pixels 131 is smaller than the pixel gap of the second sub-pixels 132.
In the display panel shown in this embodiment, the first pixel 14 is not disposed in the first region 12, so that the light transmittance of the photosensitive device corresponding to the first region 12 is improved, the density of the first pixel 14 in the second region 13 close to the first region 12 is higher, and the lens region 162 is disposed in the position, so that the lens region 162 guides a part of the light emitted by the first pixel 14 in the position to the first region 12, so that when the display panel displays, the first region 12 also displays.
Fig. 4 is a schematic structural diagram of a display panel according to a fourth embodiment of the invention. Compared with the embodiment shown in fig. 3, the difference is that the arc surface of the lens region 162 shown in this embodiment is an arc surface with a different radius, that is, the arc surface of the lens region 162 is an irregular arc.
Therefore, in the present embodiment, in order to ensure that the light emitted from the first pixel 14 after being refracted by the lens region 162 can be uniformly emitted from the display surface of the cover 16, in the present embodiment, the first pixel density of the first pixel 14 is greater at a portion closer to the first region 12.
Specifically, the pixel gaps of the first sub-pixels 131 close to the first region 12 in the second region 13 are different, wherein the pixel gaps are smaller as the pixel gaps are closer to the first region 12.
In an embodiment, the vertical distance between the arc surface of the lens region 162 and the first pixel 14 is smaller as the first region 12 is closer, and the density of the first sub-pixels 131 is greater as the first sub-pixels 12 is closer.
Referring to fig. 5, a schematic structural diagram of a display panel according to a fifth embodiment of the present invention is shown, and compared with the second embodiment shown in fig. 2, the difference is that in this embodiment, a plurality of second pixels 17 are distributed at positions of the display substrate 11 corresponding to the first region 12, and the density of the second pixels 17 is less than the density of the second sub-pixels.
Specifically, in the display panel provided in the present embodiment, the second pixels 17 with low pixel density are disposed in the first region 12. In order to enable the second pixels 17 in the first region 12 and the first pixels 14 in the second region 13 to uniformly emit light on the display surface of the cover 16, the light emitted by a portion of the first pixels 14 in the second region 13 is guided to the first region 12 through the lens region 162 in this embodiment. Specifically, the light emitted from the first pixel 14 guided to the first region 12 by the lens region 162 may be offset from or overlapped with the light emitted from the second pixel 17 in the first region 12. Taking the present embodiment as an example, the first pixels 14 in the first region 131 of the second region 13 close to the first region 12 are densely arranged, so that the light beam portion formed in the first region 12 by the lens region 162 coincides with the light beam formed by the second pixels 17 in the first region 12.
Specifically, the second pixels 17 in the first region 12 exit vertically on the display surface of the cover 16 through the first plate light-transmitting region 161.
In this embodiment, the light emitted from the first pixel 14 in the second sub-pixel 132 far away from the first region 12 is emitted from the display surface of the display region at the position corresponding to the second flat plate transparent region 163 on the cover 16; and the light emitted from the second pixel 17 in the first region 12 is emitted from the display surface of the cover 16 corresponding to the first plate transparent region 161. The light emitted by the first pixel 14 in the first sub-pixel 131 close to the first region 12 is emitted from the display surface of the display region corresponding to the lens region 162 on the cover 16, and the light formed on the cover 16 is uniformly distributed, so that the display effect of the display panel is uniform.
In another embodiment, the lens region 162 may be an arc surface, and is not limited specifically.
Referring to fig. 6, a schematic structural diagram of a display panel according to a sixth embodiment of the present invention is shown, and compared with the fifth embodiment shown in fig. 5, the difference is that in this embodiment, the first sub-pixels 131 of the second region 13 close to the first region 12 have different pixel densities. Specifically, in this embodiment, the second pixels 17 are disposed in the first region 12, and in order to make the brightness of the first region 12 and the second region 13 uniform when displaying, the light reflected to the cover 16 through the lens region 162 and the light formed on the cover 16 by the second pixels 17 on the first region 12 may be staggered, as shown in fig. 5, so that the brightness of the light on the display surfaces of the first region 12 and the second region 13 can be uniform, and further, the brightness of the display screen is uniform when displaying.
In this embodiment, the first pixels 14 in the first region 12 are uniformly arranged and have the same pixel density, and in another embodiment, the first pixels 14 in the first region 12 may also be non-uniformly arranged. In one embodiment, in order to uniformly distribute the light formed on the cover plate 16, the pixel gap between the second pixels 17 in the first region 12 may be set to be an integral multiple of the pixel gap of the second sub-pixel 132 of the second region 13 far away from the first region 12. Or such that the pixel density of the second pixels 17 in the first area 12 is an integer multiple of the density of the outgoing light rays on the cover plate.
In this embodiment, the pixel gap of the first sub-pixel 131 of the second region 13 close to the first region 12 may be set to be larger than the pixel gap of the second sub-pixel far from the first region 12, and is not limited specifically as long as the light formed on the cover plate 16 is uniformly distributed and the uniform display effect is achieved.
In the embodiments shown in fig. 1 to fig. 6, the refractive index of the lens region may be set based on the first pixel density, as long as the purpose of guiding the light emitted from the portion of the first pixel close to the first region to the display surface corresponding to the first flat light-transmitting region for uniform emission can be achieved, so as to perform uniform display in the first region.
Referring to fig. 7, which is a schematic structural view, specifically a cross-sectional view, of a display device 60 according to an embodiment of the present invention, the display device includes a photosensitive device 62 and a display panel 61. The photosensitive device 62 is disposed below the display panel 61, and specifically, the photosensitive device 62 is disposed on the non-display surface side of the display panel 61 and corresponds to the first region. And the light sensing device 62 is a camera for forming a display panel of the under-screen camera. The scheme can enable the position of the photosensitive device 62 of the display device 60 to display, and the comprehensive screen design is achieved.
Specifically, the display panel 61 may be the display panel shown in any one of the embodiments of fig. 1 to 5. In the display device shown in this embodiment, the display panel 61 does not have pixels in the first region corresponding to the photosensitive device 62, so as to improve the light transmittance of the photosensitive device corresponding to the first region, and the density of the pixels in the second region, which is staggered from the position of the photosensitive device 62, close to the first region is higher, and a lens region is provided in the position, so that the lens region guides a part of the light emitted by the pixels in the position to the first region, so that when the display panel displays, the first region also displays.
