Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and a display device including the display panel. Background Technology

[0002] With the development of display technology, more and more display devices are integrating light sensors to enable them to collect light and perform tasks such as image acquisition or fingerprint recognition based on the collected light. To increase display area, current display devices typically place the light-collecting area within the display area itself. However, in practical applications, there are often differences in display quality between the area corresponding to the light-collecting area and other display areas, affecting the user's viewing experience. Summary of the Invention

[0003] In view of the above, this application provides a display panel and a display device, the solution of which is as follows:

[0004] A display panel, comprising:

[0005] The light-emitting layer is located on a first side of the substrate, and a light-shielding layer is located on the side of the light-emitting layer away from the substrate, wherein a first region of the light-shielding layer has a plurality of first light-transmitting holes, and a second region of the light-shielding layer has a plurality of second light-transmitting holes;

[0006] The display panel includes a first display area and a second display area. The first display area is a light-collecting area, and the first area is located in the non-opening area of ​​the first display area. The second area is located in the non-opening area of ​​the second display area.

[0007] A display device includes the aforementioned display panel.

[0008] The display panel and display device including the display panel provided in this application embodiment, in addition to providing a first light-transmitting hole in the non-opening area of ​​the first display area to make the first display area have a light-collecting area, also provide a second light-transmitting hole in the non-opening area of ​​the second display area. That is, in addition to providing a first light-transmitting hole in the light-collecting area, a second light-transmitting hole is also provided in the non-light-collecting area. By providing a light-transmitting hole in the non-opening area of ​​the display area (i.e., the second display area) in the non-light-collecting area, the reflectivity of the display area (i.e., the second display area) in the non-opening area is increased, thereby reducing the difference in reflectivity between the light-collecting area and the non-light-collecting area, that is, reducing the difference in reflectivity between the first display area and the second display area, and further reducing the display difference between the light-collecting area and the non-light-collecting area, that is, reducing the display difference between the first display area and the second display area, and improving the user's viewing experience.

[0032] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] As described in the background section, in practical applications, there are differences in the display effect between the display area corresponding to the light-collecting area and other display areas in a display device, which affects the user's viewing experience.

[0035] The inventors discovered that this is because the light sensor in the display device is mainly located on the non-display surface of the display panel. In order for the light sensor to collect the light incident on the display surface of the display panel, the part of the display area of ​​the display panel corresponding to the light sensor (i.e., the light collection area) needs to ensure a certain light transmittance.

[0036] Currently, display panels primarily feature a light-transmitting area within the light-collecting region to ensure light transmittance. When light entering the light-collecting region passes through this light-transmitting area and reaches the light sensor surface, it is reflected. This results in a difference in reflectivity between the light-transmitting and non-light-transmitting areas of the display panel, leading to differences in display performance between the light-transmitting and non-light-transmitting areas. Figure 1 As shown, area A is a light-transmitting area and area B is a non-light-transmitting area. This results in a difference in the display effect between the light-collecting area and the non-light-collecting area of ​​the display panel, affecting the user's viewing experience.

[0037] In view of this, embodiments of this application provide a display panel and a display device including the display panel, optionally, such as Figure 2 As shown, the display device includes a display panel 100 and a light-collecting device 200 located on the non-display side of the display panel 100. The display area of ​​the display panel 100 has a light-collecting area, and the light-collecting device 200 collects light based on the light transmitted through the light-collecting area of ​​the display panel. It should be noted that in this embodiment, as... Figure 2 and Figure 3 As shown, the display panel 100 includes a first display area 101 and a second display area 102. The first display area 101 is a light-collecting area, and the second display area 102 is a non-light-collecting area. That is, a light-collecting device is provided on the non-display side of the display panel 100 corresponding to the position of the first display area 101. Light incident on the first display area 101 of the display panel 100 can pass through the display panel 100 and exit from the non-display side of the display panel 100, and be received by the light-collecting device 200. No light-collecting device is provided on the non-display side of the display panel 100 corresponding to the position of the second display area 102, and light incident on the second display area 102 of the display panel 100 cannot exit from the non-display side of the display panel 100.

[0038] like Figure 4 As shown, in this embodiment, the display panel includes:

[0039] The substrate 10 includes a light-emitting layer 20 located on a first side of the substrate 10 and a light-shielding layer 30 located on a side of the light-emitting layer 20 away from the substrate 10. The light-shielding layer 30 has a first region with multiple first light-transmitting holes 31 and a second region with multiple second light-transmitting holes 32. It should be noted that in this embodiment, the first region is located in the non-opening area of ​​the first display area 101, and the second region is located in the non-opening area of ​​the second display area 102, such as... Figures 4-6 As shown, the first light-transmitting hole 31 is located in the non-opening area of ​​the first display area 101, and the second light-transmitting hole 32 is located in the non-opening area of ​​the second display area 102. Optionally, the display panel further includes a cover plate 40 located on the side of the light-shielding layer away from the substrate.

[0040] Specifically, based on the above embodiments, in one embodiment of this application, the following continues... Figure 4 As shown, the display panel further includes: an encapsulation film 50 encapsulating the light-emitting layer 20 and a pixel definition layer 60 located between the substrate 10 and the encapsulation film 50. The pixel definition layer 60 has multiple openings, and the light-emitting layer 20 includes multiple light-emitting elements 21, each corresponding to one of the openings and located within the opening. It should be noted that, in this embodiment, the area where the light-emitting element 21 is located is the opening area of ​​the display panel, and the area of ​​the display area of ​​the display panel excluding the opening area is the non-opening area.

[0041] The display panel provided in this application embodiment, in addition to providing a first light-transmitting hole in the non-opening area of ​​the first display area to make the first display area have a light-collecting area, also provides a second light-transmitting hole in the non-opening area of ​​the second display area. That is, in addition to providing a first light-transmitting hole in the light-collecting area, a second light-transmitting hole is also provided in the non-light-collecting area. By providing a light-transmitting hole in the non-opening area of ​​the display area (i.e., the second display area) in the non-light-collecting area, the reflectivity of the display area (i.e., the second display area) in the non-opening area is increased, thereby reducing the difference in reflectivity between the light-collecting area and the non-light-collecting area, that is, reducing the difference in reflectivity between the first display area and the second display area, and further reducing the display difference between the light-collecting area and the non-light-collecting area, that is, reducing the display difference between the first display area and the second display area, and improving the user's viewing experience.

[0042] Optionally, in one embodiment of this application, the reflectance per unit area of ​​the first display area and the reflectance per unit area of ​​the second display area satisfy the condition of equality, so as to reduce the display difference between the first display area and the second display area and improve the user's viewing experience. The condition of equality between the reflectance per unit area of ​​the first display area and the reflectance per unit area of ​​the second display area includes: the reflectance per unit area of ​​the first display area and the reflectance per unit area of ​​the second display area are equal; it also includes: the reflectance of the area where the first light-transmitting hole is located is approximately equal to the reflectance of the area where the second light-transmitting hole is located.

[0043] It should be noted that in the above embodiments, the pixel definition layer can be a transparent film layer or an opaque film layer. This application does not limit this. The following description is based on specific circumstances.

[0044] Specifically, in one embodiment of this application, such as Figure 4 As shown, the pixel definition layer 60 is a transparent film layer. It should be noted that since the transparent film layer can transmit light, in this embodiment, the area of ​​the pixel definition layer 60 corresponding to the first light-transmitting hole 31 may not have an opening. Similarly, the area of ​​the pixel definition layer 60 corresponding to the second light-transmitting hole 32 may also not have an opening. However, this application does not limit this. In other embodiments of this application, ...

[0045] Based on the above embodiments, in one embodiment of this application, the proportion of light-transmitting area per unit area of ​​the first display area and the proportion of light-transmitting area per unit area of ​​the second display area are equal, so that the reflectivity of the first display area and the second display area are equal, thereby reducing the display difference between the first display area and the second display area and improving the user's viewing experience. It should be noted that, in this embodiment of the application, the condition that the proportion of light-transmitting area per unit area of ​​the first display area and the proportion of light-transmitting area per unit area of ​​the second display area are equal includes: the proportion of light-transmitting area per unit area of ​​the first display area and the proportion of light-transmitting area per unit area of ​​the second display area are equal, and also includes that the proportion of light-transmitting area per unit area of ​​the first display area and the proportion of light-transmitting area per unit area of ​​the second display area are approximately equal.

[0046] Based on the above embodiments, in one embodiment of this application, the area of ​​the first light-transmitting hole and the area of ​​the second light-transmitting hole satisfy the condition of equality, thereby making the reflectivity of the area where the first light-transmitting hole is located equal to the reflectivity of the area where the second light-transmitting hole is located, and thus making the reflectivity of the first display area and the second display area equal, reducing the display difference between the first display area and the second display area, and improving the user's viewing experience.

[0047] It should be noted that, in this embodiment, the equality of the area of ​​the first light-transmitting hole and the area of ​​the second light-transmitting hole includes the fact that the area of ​​the first light-transmitting hole and the area of ​​the second light-transmitting hole are equal, and also includes the fact that the area of ​​the first light-transmitting hole and the area of ​​the second light-transmitting hole are approximately equal.

[0048] In another embodiment of this application, such as Figure 7 As shown, the display panel further includes a metal layer located on the side of the pixel definition layer 60 facing the substrate 10. The metal layer includes a plurality of metal units 71. In a direction perpendicular to the plane of the display panel, each metal unit 71 corresponds to a second light-transmitting hole 32 to improve the reflectivity of the area where the second light-transmitting hole 32 is located. It should be noted that since the metal unit 71 corresponding to the area where the second light-transmitting hole 32 is located can improve the reflectivity of the area where the second light-transmitting hole 32 is located, in this embodiment, the area of ​​the second light-transmitting hole 32 is smaller than the area of ​​the first light-transmitting hole 31 to achieve the condition that the reflectivity of the area where the second light-transmitting hole 32 is located is equal to that of the area where the first light-transmitting hole 31 is located. This reduces the proportion of the area where the second light-transmitting hole 32 is located in the second display area, so that the second display area can have a larger area for setting the opening area and / or provide a larger layout space for wiring, increasing the aperture ratio of the second display area and reducing the wiring difficulty of the second display area.

[0049] Based on the above embodiments, in one embodiment of this application, the area of ​​the second light-transmitting hole is less than or equal to half the area of ​​the first light-transmitting hole, so as to reduce the area of ​​the second light-transmitting hole as much as possible while satisfying the condition that the reflectivity of the area where the second light-transmitting hole is located is equal to that of the area where the first light-transmitting hole is located, thereby reducing the proportion of the second light-transmitting hole area in the second display area, increasing the aperture ratio of the second display area, and reducing the wiring difficulty of the second display area.

[0050] Based on the above embodiments, in one embodiment of this application, such as Figure 8As shown, the display panel further includes an anode layer located between the substrate 10 and the light-emitting layer 20. The anode layer is a control electrode layer for controlling the light emission of the light-emitting layer 20. Specifically, the anode layer includes a plurality of anode units 81, and the anode units 81 correspond one-to-one with the light-emitting elements 21.

[0051] Optionally, based on the above embodiments, in one embodiment of this application, the metal layer and the anode layer are located on the same layer, that is, the metal unit 71 and the anode unit 81 are located on the same layer, so that the display panel does not increase in thickness due to the inclusion of the metal layer, making the display panel adaptable to the trend of thinner and lighter designs. It should be noted that in this embodiment, the metal unit and the anode unit can be electrically insulated, such as... Figure 8 As shown, it can also be electrically connected, such as... Figure 9 As shown, as long as it does not affect the normal operation of the light-emitting element 21, this application does not impose any limitations on this, and it depends on the specific circumstances.

[0052] Specifically, based on the above embodiments, in one embodiment of this application, the ratio of the area of ​​the second light-transmitting hole to the area of ​​the first light-transmitting hole is in the range of 20% to 40%, so as to minimize the area of ​​the second light-transmitting hole while ensuring that the reflectivity of the area where the second light-transmitting hole is located is equal to that of the area where the first light-transmitting hole is located, thereby reducing the proportion of the second light-transmitting hole area in the second display area, increasing the aperture ratio of the second display area, and reducing the wiring difficulty of the second display area.

[0053] In other embodiments of this application, the metal layer may also be disposed at other locations between the pixel definition layer and the substrate. This application does not limit this, and it depends on the specific circumstances.

[0054] It should be noted that the above embodiments are described with the metal layer located on the side of the pixel definition layer facing the substrate as an example. This application does not limit this. In other embodiments of this application, the metal layer may also be located on the side of the pixel definition layer away from the substrate.

[0055] Specifically, in one embodiment of this application, such as Figure 10 As shown, the display panel further includes a metal layer located between the light-shielding layer 30 and the pixel definition layer 60. The metal layer includes a plurality of metal units 71. In a direction perpendicular to the plane of the display panel, the metal units 71 correspond one-to-one with the second light-transmitting holes 32. The area of ​​the second light-transmitting hole 32 is smaller than the area of ​​the first light-transmitting hole 31.

[0056] Optionally, based on the above embodiments, in one embodiment of this application, such as... Figure 11 As shown, the display panel further includes a touch electrode layer located on the side of the light-shielding layer 30 facing the light-emitting layer 20. The touch electrode layer includes a plurality of touch electrodes 91, so that the display panel integrates touch functionality and improves the integration of the display panel.

[0057] Specifically, in one embodiment of this application, the touch electrode 91 is a metal electrode to reduce its resistance. It should be noted that in this embodiment, when the display panel further includes a metal unit 71, the metal unit 71 can also be located on the same layer as the touch electrode 91, such as... Figure 12 As shown, the thickness of the display panel is not increased due to the setting of the metal unit, thus adapting to the development trend of thinner and lighter display panels.

[0058] Optionally, in the above embodiments, since both the touch electrode and the metal unit are made of metal, in one embodiment of this application, the touch electrode can also be reused as the metal unit, thereby further simplifying the process of the display panel, reducing the weight and area of ​​the display panel, and being suitable for the development trend of thinner and lighter display panels.

[0059] Specifically, based on the above embodiments, in one embodiment of this application, the ratio of the area of ​​the second light-transmitting hole to the area of ​​the first light-transmitting hole is in the range of 40%-50%. This is to minimize the area of ​​the second light-transmitting hole while ensuring that the reflectivity of the area where the second light-transmitting hole is located is equal to that of the area where the first light-transmitting hole is located. This reduces the proportion of the second light-transmitting hole area in the second display area, increases the aperture ratio of the second display area, and reduces the wiring difficulty of the second display area.

[0060] In another embodiment of this application, the display panel includes both an anode layer and a touch electrode layer, that is, in this embodiment, as shown... Figure 13 As shown, the display panel further includes: an anode layer located between the substrate 10 and the light-emitting layer 20, and a touch electrode layer located between the light-shielding layer 30 and the pixel definition layer 60. The anode layer includes a plurality of anode units 81, and the touch electrode layer includes a plurality of touch electrodes 91; wherein the touch electrodes are metal electrodes.

[0061] Optionally, based on the above embodiments, in one embodiment of this application, the following continues... Figure 13As shown, some of the metal units 71 are located on the same layer as the anode unit 81, and some of the metal units 71 are located on the same layer as the touch electrode 91. This allows the multiple metal units included in the metal layer to be dispersed in the film layers occupied by the anode layer and the film layers occupied by the touch electrode layer without increasing the thickness of the display panel, thereby reducing the difficulty of the process.

[0062] It should be noted that, since the reflectivity of the anode unit is greater than that of the touch electrode, in the above embodiments, the ratio of the area of ​​the second light-transmitting hole corresponding to the metal unit located on the same layer as the anode unit to the area of ​​the first light-transmitting hole ranges from 20% to 40%, and the ratio of the area of ​​the second light-transmitting hole corresponding to the metal unit located on the same layer as the touch unit to the area of ​​the first light-transmitting hole ranges from 40% to 50%, thereby making the reflectivity of the areas where each second light-transmitting hole is located essentially equal. However, this application does not limit this, and it depends on the specific circumstances.

[0063] In other embodiments of this application, the metal layer may also be located at other positions between the light-shielding layer and the pixel definition layer. This application does not limit this, and it depends on the specific circumstances.

[0064] It should be noted that the above embodiments are all described with the pixel definition layer being a transparent film layer as an example. In other embodiments of this application, the pixel definition layer may also be a black film layer. The following describes the case where the pixel definition layer is a black film layer in conjunction with specific embodiments.

[0065] Specifically, in one embodiment of this application, such as Figure 14 As shown, the display panel includes: an encapsulation film 50 encapsulating the light-emitting layer 20 and a pixel definition layer 60 located between the substrate 10 and the encapsulation film 50, wherein the pixel definition layer 60 is a black film layer. It should be noted that, since the black film layer has light-absorbing properties, in this embodiment, the pixel definition layer 60 has multiple first openings 61, each corresponding to a first light-transmitting hole 31, to ensure that the light transmitted through the first light-transmitting hole 31 can pass through the display panel and exit from the non-display side of the display panel, where it is collected by a light-collecting device located on the non-display side of the display panel.

[0066] Optionally, based on the above embodiments, in one embodiment of this application, the projection of the first light-transmitting hole 31 on the substrate 10 is located within the projection range of the first opening 61 on the substrate 10, so that all the light transmitted by the first light-transmitting hole 31 can be transmitted through the first opening 61. However, this application does not limit this, and it depends on the specific situation.

[0067] It should be noted that, since the pixel definition layer is a black film layer, it has a light-transmitting function. Therefore, when the pixel definition layer does not have an opening in the area where the second light-transmitting hole is located, the proportion of the light-transmitting area per unit area of ​​the second display area is at least twice the proportion of the light-transmitting area per unit area of ​​the first display area. This ensures that the reflectivity of the second display area is equal to that of the first display area, thereby reducing the display difference between the first and second display areas and improving the user's viewing experience.

[0068] Specifically, based on the above embodiments, in one embodiment of this application, the density of the first light-transmitting aperture in the first display area and the density of the second light-transmitting aperture in the second display area satisfy the condition of equality, and the area of ​​the second light-transmitting aperture is at least twice the area of ​​the first light-transmitting aperture, thereby making the proportion of light-transmitting area per unit area of ​​the second display area at least twice the proportion of light-transmitting area per unit area of ​​the first display area. The condition of equality between the density of the first light-transmitting aperture in the first display area and the density of the second light-transmitting aperture in the second display area includes that the density of the first light-transmitting aperture in the first display area and the density of the second light-transmitting aperture in the second display area are equal, and also includes that the density of the first light-transmitting aperture in the first display area and the density of the second light-transmitting aperture in the second display area are approximately equal.

[0069] In another embodiment of this application, the area of ​​the first light-transmitting hole in the first display area and the area of ​​the second light-transmitting hole in the second display area are equal, and the density of the first light-transmitting hole in the second display area is at least twice the density of the first light-transmitting hole in the first display area, so that the proportion of the light-transmitting area per unit area in the second display area is at least twice the proportion of the light-transmitting area per unit area in the first display area.

[0070] In another embodiment of this application, such as Figure 15 As shown, the pixel definition layer 60 also has a plurality of second openings 62, which correspond to the second light-transmitting holes 32. By providing the second openings 62 in the pixel definition layer 60, the absorption of light transmitted through the second light-transmitting holes 332 by the pixel definition layer 60 is reduced. Optionally, in one embodiment of this application, the projection of the second light-transmitting hole 32 on the substrate 10 is located within the projection range of the second opening 62 on the substrate 10, so that all the light transmitted through the second light-transmitting hole 32 can be transmitted through the second opening 62.

[0071] It should be noted that when the pixel definition layer is provided with both a first opening and a second opening, the absorption effect of the pixel definition layer on the light transmitted through the first light-transmitting hole and the second light-transmitting hole is very weak. Therefore, in this embodiment, the proportion of the light-transmitting area per unit area of ​​the first display area and the proportion of the light-transmitting area per unit area of ​​the second display area are equal.

[0072] Based on the above embodiments, in one embodiment of this application, the area of ​​the first light-transmitting hole and the area of ​​the second light-transmitting hole satisfy the condition of equality, thereby making the reflectivity of the area where the first light-transmitting hole is located equal to the reflectivity of the area where the second light-transmitting hole is located, and thus making the reflectivity of the first display area and the second display area equal, reducing the display difference between the first display area and the second display area, and improving the user's viewing experience.

[0073] In another embodiment of this application, such as Figure 16 As shown, the display panel further includes a metal layer located on the side of the pixel definition layer 60 facing the substrate 10. The metal layer includes a plurality of metal units 71. In a direction perpendicular to the plane of the display panel, each metal unit 71 corresponds to a second light-transmitting hole 32 to improve the reflectivity of the area where the second light-transmitting hole 32 is located. It should be noted that since the metal unit corresponding to the area where the second light-transmitting hole is located can improve the reflectivity of the area where the second light-transmitting hole is located, in this embodiment, the area of ​​the second light-transmitting hole is smaller than the area of ​​the first light-transmitting hole to achieve the condition that the reflectivity of the area where the second light-transmitting hole is located is equal to that of the area where the first light-transmitting hole is located. This reduces the proportion of the area where the second light-transmitting hole is located in the second display area, so that the second display area can have a larger area for setting the opening area and / or provide a larger layout space for wiring, increasing the aperture ratio of the second display area and reducing the wiring difficulty of the second display area.

[0074] It should also be noted that, in the above embodiments, since the pixel definition layer is a black film layer and the metal layer is located on the side of the pixel definition layer facing the substrate, that is, the metal layer is located on the side of the pixel definition layer away from the light-shielding layer, therefore, in this embodiment, the pixel definition layer is provided with a second opening in the area corresponding to the second light-transmitting hole, so as to ensure that the light transmitted through the second light-transmitting hole can be irradiated onto the metal unit through the second opening and reflected by the metal unit, thereby realizing the function of improving the reflectivity by utilizing the metal unit.

[0075] Based on the above embodiments, in one embodiment of this application, the area of ​​the second light-transmitting hole is less than or equal to half the area of ​​the first light-transmitting hole, so as to reduce the area of ​​the second light-transmitting hole as much as possible while satisfying the condition that the reflectivity of the area where the second light-transmitting hole is located is equal to that of the area where the first light-transmitting hole is located, thereby reducing the proportion of the second light-transmitting hole area in the second display area, increasing the aperture ratio of the second display area, and reducing the wiring difficulty of the second display area.

[0076] Based on the above embodiments, in one embodiment of this application, such as Figure 17 As shown, the display panel further includes an anode layer located between the substrate 10 and the light-emitting layer 20. The anode layer is a control electrode layer for controlling the light emission of the light-emitting layer. Specifically, the anode layer includes a plurality of anode units 81, and the anode units 81 correspond one-to-one with the light-emitting elements 21.

[0077] Optionally, based on the above embodiments, in one embodiment of this application, the metal layer and the anode layer are located on the same layer, that is, the anode unit 81 and the metal unit 71 are located on the same layer, so that the display panel does not increase in thickness due to the inclusion of the metal layer, making the display panel adaptable to the trend of thinner and lighter designs. It should be noted that in the embodiments of this application, the metal unit and the anode unit can be electrically insulated or electrically connected, as long as it does not affect the normal operation of the light-emitting element. This application does not impose any limitations on this, and the specific choice depends on the circumstances.

[0078] Specifically, based on the above embodiments, in one embodiment of this application, the ratio of the area of ​​the second light-transmitting hole to the area of ​​the first light-transmitting hole is in the range of 20% to 40%, so as to minimize the area of ​​the second light-transmitting hole while ensuring that the reflectivity of the area where the second light-transmitting hole is located is equal to that of the area where the first light-transmitting hole is located, thereby reducing the proportion of the second light-transmitting hole area in the second display area, increasing the aperture ratio of the second display area, and reducing the wiring difficulty of the second display area.

[0079] In other embodiments of this application, the metal layer may also be disposed at other locations between the pixel definition layer and the substrate. This application does not limit this, and it depends on the specific circumstances.

[0080] It should be noted that the above embodiments are described with the metal layer located on the side of the pixel definition layer facing the substrate as an example. This application does not limit this. In other embodiments of this application, the metal layer may also be located on the side of the pixel definition layer away from the substrate. It should also be noted that when the metal layer is located between the pixel definition layer and the light-shielding layer, the light transmitted through the second light-transmitting hole will first reach the metal unit and be reflected by the metal unit, and will not illuminate the pixel definition layer and be absorbed by the pixel definition layer. Therefore, in this embodiment, the second opening may not be provided at the position of the pixel definition layer corresponding to the second light-transmitting hole area.

[0081] Specifically, in one embodiment of this application, such as Figure 18 As shown, the display panel further includes a metal layer located between the light-shielding layer 30 and the pixel definition layer 60. The metal layer includes a plurality of metal units 71. In a direction perpendicular to the plane of the display panel, the metal units 71 correspond one-to-one with the second light-transmitting holes 32. The area of ​​the second light-transmitting hole 32 is smaller than the area of ​​the first light-transmitting hole 31.

[0082] Optionally, based on the above embodiments, in one embodiment of this application, such as Figure 19 As shown, the display panel further includes a touch electrode layer located on the side of the light-shielding layer 30 facing the light-emitting layer 20. The touch electrode layer includes a plurality of touch electrodes 91, so that the display panel integrates touch functionality and improves the integration of the display panel.

[0083] Specifically, in one embodiment of this application, the touch electrode is a metal electrode to reduce its resistance. It should be noted that, in this embodiment, as... Figure 20 As shown, when the display panel also includes a metal unit 71, the metal unit 71 can also be located on the same layer as the touch electrode 91, so that the thickness of the display panel is not increased due to the setting of the metal unit 71, thus adapting to the development trend of the display panel becoming thinner and lighter.

[0084] Optionally, in the above embodiments, since both the touch electrode and the metal unit are made of metal, in one embodiment of this application, the touch electrode can also be reused as the metal unit, thereby further simplifying the process of the display panel, reducing the weight and area of ​​the display panel, and being suitable for the development trend of thinner and lighter display panels.

[0085] Specifically, based on the above embodiments, in one embodiment of this application, the ratio of the area of ​​the second light-transmitting hole to the area of ​​the first light-transmitting hole is in the range of 40%-50%. This is to minimize the area of ​​the second light-transmitting hole while ensuring that the reflectivity of the area where the second light-transmitting hole is located is equal to that of the area where the first light-transmitting hole is located. This reduces the proportion of the second light-transmitting hole area in the second display area, increases the aperture ratio of the second display area, and reduces the wiring difficulty of the second display area.

[0086] In another embodiment of this application, the display panel includes both an anode layer and a touch electrode layer, i.e., in this embodiment, as shown... Figure 21 As shown, the display panel further includes: an anode layer located between the substrate 10 and the light-emitting layer 20, and a touch electrode layer located between the light-shielding layer 30 and the pixel definition layer 60. The anode layer includes a plurality of anode units 81, and the touch electrode layer includes a plurality of touch electrodes 91; wherein the touch electrodes are metal electrodes.

[0087] Optionally, based on the above embodiments, in one embodiment of this application, the following continues... Figure 21 As shown, some of the metal units 71 are located on the same layer as the anode unit 81, and some of the metal units 71 are located on the same layer as the touch electrode 91. This allows the multiple metal units included in the metal layer to be dispersed in the film layers occupied by the anode layer and the film layers occupied by the touch electrode layer without increasing the thickness of the display panel, thereby reducing the difficulty of the process.

[0088] It should be noted that, since the reflectivity of the anode unit is greater than that of the touch electrode, in the above embodiments, the ratio of the area of ​​the second light-transmitting hole corresponding to the metal unit located on the same layer as the anode unit to the area of ​​the first light-transmitting hole ranges from 20% to 40%, and the ratio of the area of ​​the second light-transmitting hole corresponding to the metal unit located on the same layer as the touch unit to the area of ​​the first light-transmitting hole ranges from 40% to 50%, thereby making the reflectivity of each region containing the second light-transmitting hole essentially equal. However, this application does not limit this, and it depends on the specific circumstances. For ease of description, the metal unit located on the same layer as the anode layer is called the first metal unit, and the metal unit located on the same layer as the touch electrode layer is called the second metal unit. The ratio of the area of ​​the second light-transmitting hole corresponding to the first metal unit to the area of ​​the first light-transmitting hole ranges from 20% to 40%, and the ratio of the area of ​​the second light-transmitting hole corresponding to the second metal unit to the area of ​​the first light-transmitting hole ranges from 40% to 50%.

[0089] It should also be noted that, since the anode layer is located on the side of the pixel definition layer away from the light-shielding layer, and the touch electrode layer is located on the side of the pixel definition layer facing the light-shielding layer, the light transmitted through the second light-transmitting hole will first pass through the film layer where the touch electrode layer is located, then through the film layer where the pixel definition layer is located, and then reach the film layer where the anode layer is located. Therefore, in this embodiment, the pixel definition layer 60 has a second opening 62 at the position corresponding to the first metal unit, but no second opening is provided at the position corresponding to the second metal unit.

[0090] In other embodiments of this application, the metal layer may also be located at other positions between the light-shielding layer and the pixel definition layer. This application does not limit this, and it depends on the specific circumstances.

[0091] Based on any of the above embodiments, in a specific embodiment of this application, the area of ​​the first light-transmitting hole is 2*2mm or 2*3mm, but this application does not limit it and it depends on the specific situation.

[0092] It should be noted that in other embodiments of this application, the display panel may also include other structures in the display panel, such as a cathode layer, a control circuit layer, etc. Since these are well known to those skilled in the art, this application will not elaborate on them further.

[0093] Based on any of the above embodiments, in one embodiment of this application, the light-collecting device is an image-collecting device; in another embodiment of this application, the light-collecting device is a fingerprint-collecting device; and in other embodiments of this application, the light-collecting device may be other light-collecting devices. This application does not limit the specific implementation of these devices, but rather determines the appropriate device based on the circumstances.

[0094] In summary, the display panel and display device including the display panel provided in this application embodiment, in addition to providing a first light-transmitting hole in the non-opening area of ​​the first display area to make the first display area have a light-collecting area, also provide a second light-transmitting hole in the non-opening area of ​​the second display area. That is, in addition to providing a first light-transmitting hole in the light-collecting area, a second light-transmitting hole is also provided in the non-light-collecting area. By providing a light-transmitting hole in the non-opening area of ​​the display area (i.e., the second display area) in the non-light-collecting area, the reflectivity of the display area (i.e., the second display area) in the non-opening area is increased, thereby reducing the difference in reflectivity between the light-collecting area and the non-light-collecting area, that is, reducing the difference in reflectivity between the first display area and the second display area, and further reducing the display difference between the light-collecting area and the non-light-collecting area, that is, reducing the display difference between the first display area and the second display area, and improving the user's viewing experience.
