[0030] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the related art, the following will briefly introduce the drawings needed to be used in the embodiments or the related art descriptions. Obviously, the drawings in the following description are only some of the embodiments of the present application, and other embodiments can also be obtained by those skilled in the art based on these drawings.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art based on the present application are within the scope of protection of the present application.

[0033] With the screen ratio of terminal devices such as mobile phones becoming larger and larger, the scheme of setting the camera under the screen to shoot images has attracted widespread attention. In the related technology, the area of the screen corresponding to the camera not only can display images, but also has the characteristics of light transmission, so that the camera can shoot the image in front of the screen. However, the camera area needs to improve the transmittance while meeting the display requirements. In order to ensure the amount of external light when shooting under the camera, the brightness of the camera area when displaying the picture is usually low, and the display effect is poor. Therefore, how to ensure the amount of ambient light when the camera area is in the shooting state while improving the display effect of the camera area in the display state is a technical problem to be solved.

[0034] As shown in Figure 1 、 Figure 5 The embodiment of the first aspect of the application proposes a display panel. The display panel includes a display area 20 and a camera area 10, and the display panel includes a substrate 100 and a light-emitting layer 200 disposed on one side of the substrate 100. The display panel further includes a light shaping structure 300 disposed in the camera area 10. The light shaping structure 300 is disposed on the side of the light-emitting layer 200 away from the substrate 100. The camera area 10 has a shooting state and a display state that can be switched with each other. The light shaping structure 300 is configured to make the amount of ambient light of the camera area 10 in the shooting state greater than the amount of ambient light in the display state. The light shaping structure 300 is also configured to make the amount of display light of the camera area 10 in the display state greater than the amount of display light in the shooting state.

[0035] According to the display panel in the embodiment of the application, it includes a display area 20 and a camera area 10, wherein the display area 20 is a region with normal display function, and the camera area 10 is provided with an under-screen camera, so that when the camera is turned on, the image in front of the screen can be shot. The display area 20 and the camera area 10 of the display panel each include a substrate 100 and a light-emitting layer 200. In the camera area 10, the display panel further includes a light shaping structure 300 located on the side of the light-emitting layer 200 away from the substrate 100. The light shaping structure 300 is used to change the amount of ambient light or the amount of display light of the camera area 10. When the camera area 10 is in the shooting state, the light shaping structure 300 can increase the amount of ambient light, so that more ambient light can be converged on the camera, improving the light acquisition amount of the camera and further improving the shooting effect. When the camera area 10 is in the display state, the light shaping structure 300 can increase the amount of display light, thereby improving the display brightness of the camera area 10 to improve the display effect. Therefore, the display panel of the embodiment can ensure the amount of ambient light of the camera area 10 in the shooting state while improving the display effect of the camera area 10 in the display state.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the light shaping structure 300 includes a first driving electrode 310 and a liquid crystal layer 330. The orthographic projection of the first driving electrode 310 on the substrate 100 is located outside the orthographic projection of the light-emitting layer 200 on the substrate 100. The first driving electrode 310 is configured to drive the liquid crystal molecules in the liquid crystal layer 330 to deflect when the camera region 10 is in the shooting state. In related technologies, a transparent region 11 is provided around the light-emitting layer 200. In display mode, the light-emitting layer 200 can emit light. In shooting mode, ambient light A can enter the camera from the transparent region 11. In this embodiment, the orthographic projection of the first driving electrode 310 on the substrate 100 is outside the orthographic projection of the light-emitting layer 200 on the substrate 100. That is, the first driving electrode 310 is located in the transparent region 11 of the display panel. When the camera area 10 is in shooting mode, the first driving electrode 310 can drive the liquid crystal molecules in the liquid crystal layer 330 opposite to the transparent region 11 to deflect. After the liquid crystal molecules are deflected, the part of the liquid crystal layer 330 opposite to the transparent region 11 has the function of converging the light of ambient light A, that is, similar to the function of a convex lens. At this time, the amount of ambient light A can be increased.

[0037] like Figure 4 , Figure 5 As shown, in some embodiments of this application, the first driving electrode 310 is a first annular transparent electrode, which includes a first intermediate electrode 311 and a first peripheral electrode 312. When the camera area 10 is in a shooting state, the voltage of the first intermediate electrode 311 is greater than the voltage of the first peripheral electrode 312. In this embodiment, the first driving electrode 310 is made of a transparent electrode material, such as indium tin oxide (ITO). When the display panel is in shooting mode, the voltage of the first intermediate electrode 311 can be recorded as V2 and the voltage of the first peripheral electrode 312 can be recorded as V4. When V2 is greater than V4, the liquid crystal molecules in the liquid crystal layer 330 near the first annular transparent electrode will be deflected, and the deflection angle of the liquid crystal molecules near the first intermediate electrode 311 is greater than the deflection angle of the liquid crystal molecules near the first peripheral electrode 312. Since the first driving electrode 310 is annular and the first peripheral electrode 312 is arranged around the first intermediate electrode 311, the deflected liquid crystal molecules are similar to a convex lens, which can focus the ambient light A to the camera area 10, greatly improving the amount of light obtained by the camera.

[0038] In some embodiments of this application, the light-shaping structure 300 further includes a second driving electrode 320. The second driving electrode 320 is disposed opposite to the light-emitting layer 200 in the thickness direction of the display panel. The second driving electrode 320 is configured to drive the liquid crystal molecules in the liquid crystal layer 330 to deflect when the camera area 10 is in the display state. In related technologies, a transparent area 11 is disposed around the light-emitting layer 200, and the light-emitting layer 200 can emit light in the display mode. In this embodiment, the second driving electrode 320 is disposed relative to the light-emitting layer 200. When the display panel is in the display state, the second driving electrode 320 can drive the liquid crystal molecules in the liquid crystal layer 330 to deflect. After the liquid crystal molecules are deflected, the portion of the liquid crystal layer 330 opposite to the light-emitting layer 200 has the function of converging the light of the display light B, that is, similar to the function of a convex lens. At this time, the amount of light emitted by the display light B can be increased.

[0039] In some embodiments of this application, the second driving electrode 320 is a second annular transparent electrode, which includes a second intermediate electrode 321 and a second peripheral electrode 322. When the camera area 10 is in a display state, the absolute value of the voltage of the second intermediate electrode 321 is greater than the absolute value of the voltage of the second peripheral electrode 322. In this embodiment, the second driving electrode 320, like the first driving electrode 310, can also be made of a transparent electrode material, such as indium tin oxide (ITO). When the display panel is in display mode, the voltage of the second intermediate electrode 321 can be denoted as V1, and the voltage of the second peripheral electrode 322 as V3. When the absolute value of V1 is greater than the absolute value of V3, the liquid crystal molecules in the liquid crystal layer 330 near the second annular transparent electrode will be deflected. The deflection angle of the liquid crystal molecules near the second intermediate electrode 321 is greater than the deflection angle of the liquid crystal molecules near the second peripheral electrode 322. Since the second driving electrode 320 is annular and the second peripheral electrode 322 is arranged around the second intermediate electrode 321, the deflected liquid crystal molecules are similar to a convex lens, which can act as a convex lens for the display light B of the light-emitting layer 200, thereby increasing the emitted light of the display panel, greatly improving the display brightness of the camera area 10, and enhancing the display effect of the display panel. Please refer to... Figure 2 and Figure 3 In the previous embodiment, V2 and V4 can be positive electrodes relative to the reference electrode, while in this embodiment, V1 and V3 are negative electrodes relative to the reference electrode. In this way, the deflection directions of the liquid crystal molecules in the liquid crystal layers corresponding to the first driving electrode and the second driving electrode are exactly opposite. It can be understood that after the liquid crystal molecules corresponding to the first driving electrode deflect upward, they can gather more ambient light A, while after the liquid crystal molecules corresponding to the second driving electrode deflect downward, they can diffuse more display light B to the outside.

[0040] In some embodiments of this application, the display panel further includes an anode 410 and a cathode layer 420. The anode 410 is disposed on the side of the substrate 100 near the light-emitting layer 200, and the cathode layer 420 is disposed between the light-emitting layer 200 and the liquid crystal layer 330. In this embodiment, there can be multiple anodes 410, which are disposed on the side of the substrate 100 near the light-emitting layer 200. During the manufacturing process, the anode 410 can be formed first, and then the light-emitting layer 200 can be formed. The cathode layer 420 can be made of a transparent material, which can increase the amount of ambient light A entering and the amount of display light B emitting.

[0041] In some embodiments of this application, the display panel further includes an upper substrate 500, which is disposed on the side of the light-shaping structure 300 away from the light-emitting layer 200, and the liquid crystal layer 330 is disposed between the upper substrate 500 and the cathode layer 420. In this embodiment, the upper substrate 500 can effectively protect the liquid crystal layer 330. The first driving electrode 310 and the second driving electrode 320 can also be disposed on the upper substrate 500 and led out to the periphery of the liquid crystal layer 330, respectively. Different voltages are applied to the first driving electrode 310 and the second driving electrode 320 by a control circuit.

[0042] In some embodiments of this application, the display panel further includes a planarization layer 600 disposed between the substrate 100 and the cathode layer 420. In this embodiment, the light-emitting layer 200 is disposed between the substrate 100 and the cathode layer 420. By providing the planarization layer 600, the various components of the light-emitting layer 200 can be prevented from being exposed, thereby achieving the effect of protecting the light-emitting layer 200.

[0043] like Figure 5 and Figure 6As shown, in some other embodiments of this application, the camera area 10 includes a pixel area 210 and a transparent area 220, and the light shaping structure 300 includes an electrochromic layer 340. The electrochromic layer 340 is disposed on the side of the light-emitting layer 200 away from the substrate 100. The light-emitting layer 200 is disposed in the pixel area 210. The electrochromic layer 340 includes a first color-changing area 341 and a second color-changing area 342. The first color-changing area 341 is located in the pixel area 210, and the second color-changing area 342 is located in the transparent area 220. When the camera area 10 is in the shooting state, both the first color-changing area 341 and the second color-changing area 342 are in a transparent state; when the camera area 10 is in the display state, both the first color-changing area 341 and the second color-changing area 342 are in a colored state. In this embodiment, the camera area 10 of the display panel includes a pixel area 210 capable of displaying colors and a transparent area 220 surrounding the pixel area 210. It can be understood that the light-emitting layer 200 may include light-emitting components disposed in the pixel area 210 of the display panel for emitting light of different colors, such as red, blue and green. In this embodiment, the electrochromic layer 340 is composed of a first color-changing region 341 and a second color-changing region 342. When the camera area 10 is in the shooting state, both the first color-changing region 341 and the second color-changing region 342 are transparent, which can increase the amount of ambient light entering. When the camera area 10 is in the display state, both the first color-changing region 341 and the second color-changing region 342 are colored. Since the first color-changing region 341 is located in the pixel area 210, when it becomes colored, it can absorb some ambient light, which can reduce the reflection of external ambient light. The second color-changing region 342 is located in the transparent area 220. When the color of the second color-changing region 342 is the same as the color of the pixel area 210, it can play the role of displaying pixels, which can improve the display effect of the camera area 10 in the display state.

[0044] In related technologies, the display panel also includes a circular polarizer 700, which is located on the side of the light-emitting layer 200 away from the substrate 100. The circular polarizer 700 can reflect external ambient light, thereby increasing the display effect of the display panel. In some specific embodiments of this application, the circular polarizer 700 can be provided in the display area 20, while the circular polarizer 700 is not provided in the camera area 10. In this way, when the camera area 10 is in shooting mode, more ambient light can be concentrated into the camera area 10, thereby increasing the amount of light captured by the camera.

[0045] In some embodiments of this application, the light-shaping structure 300 includes a third driving electrode 350, which is disposed opposite to the first color-changing region 341 in the thickness direction of the display panel. In this embodiment, the third driving electrode 350 can apply a voltage to the electrochromic layer 340 of the first color-changing region 341. For example, when the camera area 10 is in the shooting state, the third driving electrode 350 may not apply a voltage, and the electrochromic layer 340 in the first color-changing region 341 is in a transparent state. When the camera area 10 is in the display state, the third driving electrode 350 can apply a voltage to it, and the electrochromic layer 340 in the first color-changing region 341 is in a colored state.

[0046] In some embodiments of this application, the light-shaping structure 300 includes a fourth driving electrode 360, which is disposed opposite to the second color-changing region 342 in the thickness direction of the display panel. In this embodiment, the fourth driving electrode 360 ​​can apply a voltage to the electrochromic layer 340 of the second color-changing region 342. For example, when the camera area 10 is in the shooting state, the fourth driving electrode 360 ​​may not apply a voltage, and the electrochromic layer 340 in the second color-changing region 342 is in a transparent state. When the camera area 10 is in the display state, the fourth driving electrode 360 ​​can apply a voltage to it, and the electrochromic layer 340 in the second color-changing region 342 is in a colored state.

[0047] In related technologies, in order to maintain a certain amount of light intake in the camera area 10, some of the light-emitting elements in the light-emitting layer 200 are reduced. This will undoubtedly weaken the display effect. In this embodiment, the voltage applied by the fourth driving electrode 360 ​​can be set according to the data voltage of the light-emitting elements of the adjacent light-emitting layer 200. For example, when the adjacent light-emitting layer 200 emits blue light, the fourth driving electrode 360 ​​can also drive the electrochromic layer 340 of the second color-changing area 342 to turn into blue light. In this way, the second color-changing area 342 can serve as a display pixel to compensate for the problem of weakened display effect caused by the reduction in the number of light-emitting elements in the camera area 10.

[0048] like Figure 7 As shown, in some embodiments of this application, both the third driving electrode 350 and the fourth driving electrode 360 ​​are transparent electrodes. In this embodiment, the third driving electrode 350 can be designed as a completely transparent electrode, corresponding to the first color-changing region 341. The fourth driving electrode 360 ​​can be designed as a transparent block electrode, corresponding to the second color-changing region 342. Please refer to... Figure 7The connected lines can also be set to transparent wiring, so that when the camera area 10 is in shooting mode, the amount of ambient light entering can be further increased, and when the camera area 10 is in display mode, the amount of display light emitting can be further increased.

[0049] In some embodiments of this application, the display panel further includes a cathode layer 420, a first color-changing region 341 disposed between the third driving electrode 350 and the cathode layer 420, and a second color-changing region 342 disposed between the fourth driving electrode 360 ​​and the cathode layer 420. In this embodiment, the cathode layer 420 may also be made of a transparent material, which can increase the amount of ambient light entering during shooting and the amount of display light emitting during display. In this embodiment, the lower electrode of the electrochromic layer 340 of the first color-changing region 341 and the second color-changing region 342 can be shared with the cathode layer 420. That is, the third driving electrode 350 and the cathode layer 420 work together to drive the color of the electrochromic layer 340 of the first color-changing region 341 to change, and the fourth driving electrode 360 ​​and the cathode layer 420 work together to drive the color of the electrochromic layer 340 of the second color-changing region 342 to change. For example, assuming that the cathode layer 420 is denoted as V0, the third driving electrode 350 is denoted as V1, and the second driving electrode 320 is denoted as V2, when the camera area 10 is in the shooting state, V1 = V2 = V0. At this time, the electrochromic layers 340 of the first color-changing region 341 and the second color-changing region 342 are both in a transparent state, so that more ambient light can be gathered on the camera. When the camera area 10 is in display mode, V1 > V0. At this time, the electrochromic layer 340 of the first color-changing area 341 changes to a colored state to reduce the reflected ambient light. The voltage of V2 can be set according to the data voltage of the light-emitting device of the adjacent light-emitting layer 200 so that it is consistent with the color emitted by the light-emitting layer 200, so as to serve as a display pixel and make up for the problem of weakened display effect caused by the reduction in the number of light-emitting components in the camera area 10.

[0050] In some embodiments of this application, the display panel further includes an encapsulation layer 800, which is disposed on the side of the electrochromic layer 340 away from the light-emitting layer 200. In this embodiment, the encapsulation layer 800 can be a thin-film encapsulation structure, which can be a stacked inorganic thin-film encapsulation, or a stacked inorganic or organic thin-film encapsulation. By covering the electrochromic layer 340 with the encapsulation layer 800, the electrochromic layer 340 is protected.

[0051] An embodiment of the second aspect of this application provides a display device including the display panel in any embodiment of the first aspect.

[0052] According to the display device in the embodiments of this application, since it includes the display panel in any embodiment of the first aspect, it also has the beneficial effects of any embodiment of the first aspect. Specifically, the display panel includes a display area 20 and a camera area 10, wherein the display area 20 is an area with normal display function, and the camera area 10 is provided with an under-display camera, so that when the camera is turned on, it can capture images in front of the screen. Both the display area 20 and the camera area 10 of the display panel include a substrate 100 and a light-emitting layer 200. In the camera area 10, the display panel also includes a light-shaping structure 300, which is located on the side of the light-emitting layer 200 away from the substrate 100. The light-shaping structure 300 is used to change the amount of ambient light entering the camera area 10 or the amount of display light emitting. When the camera area 10 is in the shooting state, the light-shaping structure 300 can increase the amount of ambient light entering, so that more ambient light can be gathered on the camera, increasing the amount of light captured by the camera, thereby improving the shooting effect. When the camera area 10 is in display mode, the light shaping structure 300 can increase the amount of light emitted from the display area, thereby increasing the display brightness of the camera area 10 and improving the display effect. Therefore, the display device of this embodiment can improve the display effect of the camera area 10 while ensuring the amount of ambient light entering the device.
