In the related art, in the under-screen camera structure in the full-screen, since the camera area in the full-screen also has a display function, a plurality of light-emitting units are provided in the camera area. The anode structure in the light-emitting unit is a light-tight structure, so that external light is blocked when entering the light-emitting unit. Light can only penetrate through gaps among the light-emitting units and enter the camera below the camera area. This makes the regional light transmissivity of camera in the display panel poor, influences the function of making a video recording of camera under the screen.
In order to solve the above problem, embodiments of the present invention provide a display panel and a display device, which will be described in detail below with reference to the accompanying drawings. The display panel may be an electroluminescent display panel or a photoluminescent display panel. In the case where the display panel is an electroluminescent display panel, the electroluminescent display panel may be an OLED (Organic Light-Emitting Diode) or a QLED (Quantum Dot Light-Emitting Diode). In case the display panel is a photoluminescent display panel, the photoluminescent display panel may be a quantum dot photoluminescent display panel. In addition, the display panel can also be a display panel with a touch function.
As shown in fig. 1 to 4, a display panel 100 provided in an embodiment of the present application includes a display area including a camera area 110 and a non-camera area 120 surrounding the camera area 110. The display panel 100 includes a substrate 1, a display function layer 2, and a touch function layer 3. The display function layer 2 is located on one side of the substrate 1, and the display function layer 2 includes a plurality of anode structures 21 located in the camera area 110 and distributed at intervals. The touch functional layer 3 is located on a side of the display functional layer 2 away from the substrate 1, the touch functional layer 3 includes an organic layer 31, the organic layer 31 includes a plurality of first light modulation devices 311, at least one first light modulation device 311 of the plurality of first light modulation devices 311 is disposed corresponding to at least one anode structure 21, and the plurality of first light modulation devices 311 are configured to refract the light 300 incident to the first light modulation device 311, so that the refracted part of the light 300 is incident between the plurality of anode structures 21.
In the display panel 100 provided in the embodiment of the present application, the display panel 100 includes a substrate 1, a display functional layer 2, and a touch functional layer 3. The display functional layer 2 comprises a plurality of anode structures 21 arranged in the camera area 110. The touch functional layer 3 includes an organic layer 31, the organic layer 31 includes a plurality of first light modulation devices 311, and at least one first light modulation device 311 of the plurality of first light modulation devices 311 is disposed corresponding to at least one anode structure 21. Further, a plurality of first light modulation devices 311 may be disposed corresponding to the plurality of anode structures 21 one to one, and each of the first light modulation devices 311 is located above one of the anode structures 21 along the propagation path of the light 300, so that the light 300 first passes through the first light modulation device 311 and then propagates to the anode structure 21. The plurality of first light modulation devices 311 are configured to refract the light 300 incident to the first light modulation devices 311, so that the refracted light 300 can be incident between the plurality of anode structures 21. That is, the first light modulation device 311 can refract the light 300 originally incident on the anode structure 21, and change the propagation path of the light 300, so that part of the light 300 is not blocked by the anode structures 21 and enters the camera 200 below the display panel 100 through the gap between the anode structures 21, thereby improving the transmittance of the camera area 110 of the display panel 100.
In some embodiments, as shown in fig. 2, the at least one first light modulation device 311 includes a first refraction surface 3111 facing a side of the anode structure 21, the first refraction surface 3111 is arc-shaped, and an opening of the first refraction surface 3111 is away from the anode structure 21.
In the embodiment of the present application, as shown in fig. 3, the touch functional layer 3 may include a buffer layer 32, a bridge layer 33, an insulating layer 34, a touch pattern layer 35, and a protective layer 36, which are located on one side of the display functional layer 2 away from the substrate base plate 1 and sequentially arranged along a direction away from the display functional layer 2. The organic layer 31 includes an insulating layer 34 and a protective layer 36, and thus the first light modulation device 311 may be disposed on the insulating layer 34, and the first light modulation device 311 may also be disposed on the protective layer 36, which is not specifically limited in this embodiment.
In the embodiment of the present application, the plurality of first refractive surfaces 3111 may be obtained by patterning the insulating layer 34. Specifically, the insulating layer 34 or the protective layer 36 is patterned to form a plurality of first refraction surfaces 3111, where the first refraction surfaces 3111 are located above the anode structures 21 and are used for refracting the light 300 originally incident on the anode structures 21 and changing a propagation path of the light 300, so that part of the light 300 is not blocked by the anode structures 21 and enters the camera 200 below the display panel 100 through a gap between the anode structures 21, and the transmittance of the camera area 110 is improved.
Taking the first light modulation device 311 disposed on the protection layer 36 as an example, the process of forming the first refractive surfaces 3111 may be: after the protective layer 36 is coated on the touch pattern layer 35, the protective layer 36 is exposed and developed, and a plurality of arc-shaped first refraction surfaces 3111 are formed on the surface of the protective layer 36 on the side away from the touch pattern layer 35. Here, in order to refract the light 300 at the first refractive surface 3111, refractive indexes of materials on both sides of the first refractive surface 3111 are different, and in one example, a refractive index of a material on an upper side of the first refractive surface 3111 is smaller than a refractive index of a material on a lower side of the first refractive surface 3111 in a propagation direction of the light 300.
In some embodiments, as shown in fig. 3, the organic layer 31 includes an insulating layer 34 and a protective layer 36 on a side of the insulating layer 34 away from the display functional layer 2, and the at least one first light modulation device 311 includes a plurality of second refractive surfaces 3112 and a plurality of third refractive surfaces 3113. The plurality of second refractive surfaces 3112 may be formed by patterning the camera area 110 of the insulating layer 34. The plurality of second refraction surfaces 3112 are disposed obliquely, a side of the plurality of second refraction surfaces 3112 close to the anode structure 21 is close to each other, and a side of the plurality of second refraction surfaces 3112 far from the anode structure 21 is far from each other. The third refractive surfaces 3113 can be formed by patterning the camera area 110 of the protective layer 36. The plurality of third refractive surfaces 3113 are disposed obliquely, a side of the plurality of third refractive surfaces 3113 close to the anode structure 21 is close to the anode structure 21, a side of the plurality of third refractive surfaces 3113 away from the anode structure 21 is far from the anode structure 21, an orthographic projection of a side of at least one third refractive surface 3113 away from the anode structure 21 on the display functional layer 2 is located outside the anode structure 21, and the plurality of third refractive surfaces 3113 are configured to receive the light ray 300 refracted by the second refractive surface 3112 and refract the refracted light ray 300 for a second time.
In the embodiment, as shown in fig. 4, after the light beam 300 is incident on the plurality of second refraction surfaces 3112, the light beam 300 is refracted on the plurality of second refraction surfaces 3112 due to the difference in refractive index between the materials on both sides of the second refraction surfaces 3112, and the refracted light beam 300 is incident on the plurality of third refraction surfaces 3113 provided opposite to the plurality of second refraction surfaces 3112, and the refracted light beam 300 is refracted twice on the plurality of third refraction surfaces 3113 due to the difference in refractive index between the materials on both sides of the third refraction surfaces 3113. An orthographic projection of the side of the at least one third refractive surface 3113 facing away from the anode structure 21 on the display functional layer 2 is located outside the anode structure 21, so that the twice refracted light ray 300 can pass through the insulating layer 34 and enter the outside of the anode structure 21. Alternatively, the orthographic projection of the side of each third refractive surface 3113 away from the anode structure 21 on the display functional layer 2 is located outside the anode structure 21, so that more light rays 300 can be refracted by the third refractive surfaces 3113 and then enter the periphery of the anode structure 21.
In some embodiments, the refractive index n1 of the material of the side of the second refractive surface 3112 remote from the third refractive surface 3113 is less than the refractive index n2 of the material of the side of the second refractive surface 3112 proximate to the third refractive surface 3113; the refractive index n3 of the material of the third refractive surface 3113 on the side closer to the second refractive surface 3112 is greater than the refractive index n4 of the material of the third refractive surface 3113 on the side farther from the second refractive surface 3112. In addition, the refractive index of the material on the side where the second refractive surface 3112 and the third refractive surface 3113 are close to each other may be the same, that is, n2 is equal to n3, and the refractive index of the material on the side where the second refractive surface 3112 and the third refractive surface 3113 are far from each other may also be the same, that is, n1 is equal to n4, so that the probability that the light 300 is refracted at the boundary between the protective layer 36 and the insulating layer 34 is reduced, the propagation path of the light 300 is made simpler, and the transmittance of the camera area 110 is further improved.
In the embodiment of the present application, the number of the second refractive surfaces 3112 and the third refractive surfaces 3113 can be set according to actual requirements, and the embodiment of the present application is not particularly limited thereto. In one example, the number of the second and third refractive surfaces 3112 and 3113 is four.
In some embodiments, as shown in fig. 4, a plurality of second refractive surfaces 3112 and a plurality of third refractive surfaces 3113 are disposed in a one-to-one correspondence, and each second refractive surface 3112 is parallel to one third refractive surface 3113. As shown in fig. 4, the second refractive surface 3112 and the third refractive surface 3113 are disposed in parallel, so that an incident angle of the light 300 incident on the second refractive surface 3112 is the same as a refraction angle of the light 300 after being refracted twice by the third refractive surface 3113, thereby making a propagation path of the light 300 simpler, and enabling the light 300 to enter the camera 200 below the display panel 100 through more gaps between the anode structures 21, further improving light transmittance of the camera area 110.
In some embodiments, the orthographic projection of the plurality of second refractive surfaces 3112 on the display functional layer 2 is located inside the orthographic projection of the plurality of third refractive surfaces 3113 on the display functional layer 2, or the orthographic projection of the plurality of second refractive surfaces 3112 on the display functional layer 2 partially overlaps the orthographic projection of the plurality of third refractive surfaces 3113 on the display functional layer 2.
In the embodiment of the present application, as shown in fig. 4, the sides of the second and third refractive surfaces 3112 and 3113 close to the anode structure 21 are not connected, so that the orthographic projection of the second and third refractive surfaces 3112 and 3113 on the display functional layer 2 can be a hollow pattern. Specifically, when the number of the second refractive surfaces 3112 and the third refractive surfaces 3113 is large (for example, 10 or more), the orthographic projection of the second refractive surfaces 3112 and the third refractive surfaces 3113 on the display functional layer 2 is substantially annular. The orthographic projection of the plurality of second refractive surfaces 3112 on the display functional layer 2 is located inside the orthographic projection of the plurality of third refractive surfaces 3113 on the display functional layer 2, that is, as shown in fig. 4, a distance L1 between upper sides of two second refractive surfaces 3112 disposed opposite to each other is smaller than a distance L3 between lower sides of two third refractive surfaces 3113 disposed opposite to each other in the propagation direction of the light ray 300.
Further, the orthographic projection of the plurality of second refractive surfaces 3112 on the display functional layer 2 partially overlaps the orthographic projection of the plurality of third refractive surfaces 3113 on the display functional layer 2, and it is understood that, as shown in fig. 4, L1 is larger than L3 and L1 is smaller than a distance L2 between upper sides of two oppositely disposed third refractive surfaces 3113 in the propagation direction of the light ray 300. Based on this, the light 300 refracted by the second refraction surface 3112 can be incident on the third refraction surface 3113 for the second refraction, so that more light 300 can be incident on the gap between the anode structures 21 through the second refraction, thereby improving the transmittance of the camera area 110. The sizes of L1, L2, and L3 may be set according to actual requirements, for example, according to the size of the anode structure 21, which is not specifically limited in the embodiments of the present application.
In some embodiments, the inclination angles of the second refractive surfaces 3112 are less than or equal to 45 degrees, and/or the inclination angles of the third refractive surfaces 3113 are less than or equal to 45 degrees, which reduces the probability of total reflection when the light 300 is incident on the second refractive surface 3112 or the third refractive surface 3113 when the inclination angles of the second refractive surface 3112 and the third refractive surface 3113 are too large, so that more light 300 can be incident on the gaps between the anode structures 21, thereby further improving the transmittance of the camera area 110.
In some embodiments, as shown in fig. 3, the display function layer 2 further comprises a driving circuit 22, a transparent metal routing structure 23 and at least one planarization layer 24. The drive circuit 22 is provided in the non-imaging region 120. One end of the transparent metal routing structure 23 is connected to the driving circuit 22, the other end of the transparent metal routing structure 23 extends to the camera area 110 and is connected to the anode structure 21, and the transparent metal routing structure 23 includes at least one layer of transparent metal routing 231. Each layer of transparent metal traces 231 is formed on a corresponding one of the planarization layers 24.
In the embodiment of the present application, the driving circuit 22 is disposed in the non-imaging region 120, and the driving circuit 22 is connected to the anode structure 21 of the camera region 110 through the transparent metal routing structure 23 to drive the light emitting unit corresponding to the anode structure 21. The material of the transparent metal routing structure 23 may include transparent metal oxide such as ITO (indium tin oxide), IZO (indium zinc oxide), etc. to reduce the influence of the transparent metal routing structure 23 on the light transmittance of the camera area 110. The transparent metal routing structure 23 may include a plurality of layers of transparent metal routing lines 231, so as to reduce the routing density of the signal lines distributed in each layer, reduce the impedance of the transparent metal routing structure 23, and reduce the routing density of the signal lines in each layer when the display panel 100 is used in an application scenario with high PPI (pixel density), which is more beneficial to the high PPI of the display panel 100. In addition, each layer of transparent metal traces 231 is formed on a corresponding planarization layer 24, that is, the planarization layer 24 is disposed between each two layers of transparent metal traces 231 in the stacked arrangement, so as to space the transparent metal traces 231 in the stacked arrangement, thereby reducing the probability of wire jumping among the multiple layers of transparent metal traces 231.
In some embodiments, the at least one planarization layer 24 includes a plurality of second light modulation devices 241, and at least one second light modulation device 241 is disposed corresponding to at least one anode structure 21. Alternatively, the plurality of second light modulation devices 241 and the plurality of anode structures 21 are disposed in a one-to-one correspondence. The plurality of second light modulation devices 241 are configured to receive and condense a portion of the light rays 300 refracted by the plurality of first light modulation devices 311 and incident between the plurality of anode structures 21.
In the embodiment of the present application, as shown in fig. 4, the light 300 irradiated to the plurality of first light modulation devices 311 is refracted and dispersed, and a part of the refracted light 300 can be incident between the plurality of anode structures 21 and then enter the camera 200 below the camera area 110. In the related art, since part of the light outside the display panel 100 can also directly enter the camera 200 through the gaps between the plurality of anode structures 21, the refracted light 300 is difficult to be distinguished from the light directly incident between the plurality of anode structures 21, thereby affecting the imaging effect of the camera 200. In the embodiment of the present application, the plurality of second light adjusting devices 241 are configured to converge the light 300 refracted by the plurality of first light adjusting devices 311, so that the refracted light 300 converges in a part of the camera area covered by the anode structure 21, and the light refracted by the plurality of first light adjusting devices 311 can be distinguished from the light directly entering the camera 200, thereby improving the imaging effect of the camera 200.
In some embodiments, the at least one planarization layer 24 includes a first planarization layer 242 and a second planarization layer 243 on a side of the first planarization layer 242 adjacent to the substrate 1, and the at least one second light modulation device 241 includes a plurality of fourth refraction surfaces 2411 and a plurality of fifth refraction surfaces 2412. The plurality of fourth refraction surfaces 2411 may be formed by patterning the camera head region 110 of the first planarization layer 242, the plurality of fourth refraction surfaces 2411 are disposed obliquely, one side of the plurality of fourth refraction surfaces 2411 close to the anode structure 21 is close to the other side of the plurality of fourth refraction surfaces 2411 far from the anode structure 21. An orthographic projection of one side of the at least one fourth refraction surface 2411 close to the anode structure 21 on the substrate base plate 1 is positioned outside an orthographic projection of the corresponding anode structure 21 on the substrate base plate 1. Optionally, an orthographic projection of each fourth refraction surface 2411 on the substrate base plate 1 on a side close to the anode structure 21 is located outside an orthographic projection of the corresponding anode structure 21 on the substrate base plate 1. The fifth refractive surfaces 2412 may be formed by patterning the camera head region 110 of the second planarizing layer 243. The fifth refraction surfaces 2412 are obliquely arranged, one side of each fifth refraction surface 2412 close to the anode structure 21 is close to one side, and one side of each fifth refraction surface 2412 far away from the anode structure 21 is far away from one side. Among them, the material of the first and second planarizing layers 242 and 243 may include PI (Polyimide) or the like.
In the embodiment of the present application, the fifth refraction surfaces 2412 are used for performing secondary refraction on the light 300 refracted by the fourth refraction surfaces 2411. Specifically, as shown in fig. 4, the light 300 refracted by the plurality of first light modulation devices 311 enters the outside of the anode structure 21 and then enters the fourth refraction surface 2411 below the anode structure 21. Because the refractive indexes of the materials on the two sides of the fourth refraction surface 2411 are different, the refracted light 300 is refracted for the third time on the fourth refraction surface 2411, the refracted partial light 300 is incident on the fifth refraction surface 2412 opposite to the fourth refraction surface 2411, and because the refractive indexes of the materials on the two sides of the fifth refraction surface 2412 are also different, the refracted partial light 300 for the third time is refracted for the fourth time on the fifth refraction surface 2412, and the refracted light 300 for the fourth time enters the camera 200 below. The light 300 refracted by the fifth refraction surface 2412 can be converged into a part of the camera area covered by the anode structure 21, so that the light 300 refracted by the plurality of first light adjusting devices 311 can be distinguished from the light directly entering the camera 200, and the imaging effect of the camera 200 is improved.
In some embodiments, the refractive index n5 of the material of the side of the fourth refractive surface 2411 away from the fifth refractive surface 2412 is less than the refractive index n6 of the material of the side of the fourth refractive surface 2411 close to the fifth refractive surface 2412; a refractive index n7 of a material of the fifth refractive surface 2412 on a side close to the fourth refractive surface 2411 is larger than a refractive index n8 of a material of the fifth refractive surface 2412 on a side far from the fourth refractive surface 2411. In addition, n6 may be equal to n7, and n5 may be equal to n8, so as to reduce the probability of refraction of the light 300 at the boundary between the first and second planarizing layers 242 and 243, so that the propagation path of the light is simpler, and the light 300 can be more converged into the portion of the camera head area covered by the anode structure 21.
In some embodiments, the orthographic projection of the plurality of fourth refraction surfaces 2411 on the substrate base plate 1 is located outside the orthographic projection of the plurality of fifth refraction surfaces 2412 on the substrate base plate 1, or the orthographic projection of the plurality of fourth refraction surfaces 2411 on the substrate base plate 1 is partially overlapped with the orthographic projection of the plurality of fifth refraction surfaces 2412 on the substrate base plate 1.
In the embodiment of the application, as shown in fig. 4, the sides of the plurality of fourth refractive surfaces 2411 and the plurality of fifth refractive surfaces 2412 close to the anode structure 21 are not connected, so that the orthographic projections of the plurality of fourth refractive surfaces 2411 and the plurality of fifth refractive surfaces 2412 on the display functional layer 2 may be hollow patterns. Specifically, when the number of the fourth refractive surfaces 2411 and the fifth refractive surfaces 2412 is large (for example, greater than or equal to 10), the orthographic projections of the fourth refractive surfaces 2411 and the fifth refractive surfaces 2412 on the display functional layer 2 are substantially annular. The orthographic projection of the plurality of fourth refraction surfaces 2411 on the substrate base plate 1 is positioned outside the orthographic projection of the plurality of fifth refraction surfaces 2412 on the substrate base plate 1, that is, in the propagation direction of the light ray 300, the distance L4 between the upper sides of two oppositely-arranged fourth refraction surfaces 2411 is greater than the distance L6 between the lower sides of two oppositely-arranged fifth refraction surfaces 2412.
Further, an orthographic projection of the plurality of fourth refraction surfaces 2411 on the base substrate 1 partially overlaps with an orthographic projection of the plurality of fifth refraction surfaces 2412 on the base substrate 1, and it can be understood that, as shown in fig. 4, in the propagation direction of the light ray 300, L4 is smaller than L6, and a distance L5 between lower sides of the plurality of fourth refraction surfaces 2411 is larger than L6. In the embodiment of the present disclosure, more of the light 300 refracted by the fourth refraction surface 2411 may be incident on the fifth refraction surface 2412 for further refraction, so that more of the light 300 can enter the camera 200 after being refracted by the fifth refraction surface 2412. The sizes of L4, L5, and L6 may be set according to actual requirements, for example, according to the size of the anode structure 21, which is not specifically limited in the embodiments of the present application.
In some embodiments, as shown in fig. 4, a plurality of fourth refractive surfaces 2411 and a plurality of fifth refractive surfaces 2412 are disposed in a one-to-one correspondence, and each fourth refractive surface 2411 is parallel to one fifth refractive surface 2412. As shown in fig. 4, the fourth refractive surface 2411 and the fifth refractive surface 2412 are disposed in parallel, so that the incident angle of the light 300 incident on the fourth refractive surface 2411 is the same as the refractive angle of the light 300 refracted again by the fifth refractive surface 2412, thereby simplifying the propagation path of the light 300 and enabling the light 300 to be more converged into the part of the camera area covered by the anode structure 21.
In some embodiments, the inclination angles of the fourth refraction surfaces 2411 are less than or equal to 45 degrees, and/or the inclination angles of the fifth refraction surfaces 2412 are less than or equal to 45 degrees, so that the probability of total reflection when the light 300 is incident on the fourth refraction surface 2411 or the fifth refraction surface 2412 when the inclination angle of the fourth refraction surface 2411 and the fifth refraction surface 2412 is too large is reduced, and more light 300 can be converged into a part of the camera area covered by the anode structure 21.
The embodiment of the present application further provides a display device, which includes the display panel 100 described above. In the embodiment of the present application, the display device includes, but is not limited to, a mobile phone, a tablet computer, a display, a television, a picture screen, an advertisement screen, electronic paper, and the like.
