Description

Technical Field

[0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] As people's requirements for the screen-to-body ratio of electronic consumer products such as mobile phones are getting higher and higher, technologies such as water drop screens and notch screens have emerged, and the screen-to-body ratio has been greatly improved. Until the emergence of the "under-screen camera" technology to achieve full-screen display, the screen-to-body ratio has finally been maximized. In related technologies, a transparent display area that can be used for displaying and collecting images at the same time is set on the display panel, and the photosensitive device is set below the transparent display area.

[0003] The inventors have discovered that there are at least the following problems in the prior art: since the transparent display area still needs to be provided with display components, these display components will cause low light transmittance in the transparent display area and poor imaging quality of the photosensitive device. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a display panel and a display device, which can improve the light transmittance of the second display area, facilitate the light collection of the photosensitive device below the second display area in the display device, and improve the imaging quality of the photosensitive device.

[0005] To solve the above technical problems, an embodiment of the present invention provides a display panel, having a first display area and a second display area, the light transmittance of the first display area is less than the light transmittance of the second display area, comprising: a first pixel, located in the first display area, each of the first pixels including a plurality of first light-emitting sub-pixels of different light-emitting colors, and a first color filter is arranged on the light-emitting side of each of the first light-emitting sub-pixels; a second pixel, located in the second display area, each of the second pixels including a plurality of second light-emitting sub-pixels of different light-emitting colors, and a second color filter is arranged on the light-emitting side of each of the second light-emitting sub-pixels; the first color filter and the second color filter are in the same film layer, and space is left or a transparent block is arranged between adjacent second color filters.

[0006] An embodiment of the present invention further provides a display device, comprising: a photosensitive device, and the above-mentioned display panel; the photosensitive device is located on a side of the second light-emitting sub-pixel away from the second color filter.

[0007] Compared with the prior art, the embodiments of the present invention have the advantages that the first color filter and the second color filter are in the same film layer, and spaces are left or transparent blocks are set between adjacent second color filters, so that light can pass through the empty areas or transparent blocks between adjacent second color filters and exit the display panel, thereby improving the light transmittance of the second display area, which is beneficial to the light collection of the photosensitive device below the second display area in the display device, thereby improving the imaging quality of the photosensitive device.

[0008] In addition, the light-emitting area of ​​the first light-emitting sub-pixel of the same light-emitting color is larger than the light-emitting area of ​​the second light-emitting sub-pixel; the first pixel arrangement structure formed by the first light-emitting sub-pixel is the same as the second pixel arrangement structure formed by the second light-emitting sub-pixel. By setting the light-emitting area of ​​the first light-emitting sub-pixel in the first display area to be larger, a better display effect can be ensured, and by setting the light-emitting area of ​​the second light-emitting sub-pixel in the second display area to be smaller, the light transmittance of the second display area can be increased, so as to improve the imaging quality of the photosensitive device under the second display area.

[0009] In addition, the edges of adjacent first color filters are overlapped and / or separated by a patterned light shielding layer. This arrangement can prevent the reflected light inside the display panel from being collected by the photosensitive device under the second display area in the display device, thereby improving the imaging quality of the photosensitive device.

[0010] In addition, each of the first color filters is any one of a red color resist layer, a green color resist layer, and a blue color resist layer, and the overlapping portion of adjacent first color filters includes any two or three of the red color resist layer, the green color resist layer, and the blue color resist layer that are overlapped. When the overlapping portion of adjacent first color filters includes the red color resist layer, the green color resist layer, and the blue color resist layer that are overlapped, the overlapping portion of adjacent first color filters can better block light, prevent the reflected light inside the display panel from being collected by the photosensitive device under the second display area in the display device, and improve the imaging quality of the photosensitive device.

[0011] In addition, it also includes: a substrate; a device layer, located on the substrate, the first pixel circuit is located on the device layer; and a pixel definition layer, located on the device layer, the pixel definition layer includes a first pixel opening located in the first display area and a second pixel opening located in the second display area; the first light-emitting sub-pixel includes a first light-emitting structure, a first electrode and a second electrode, the first light-emitting structure is located in the first pixel opening, the first electrode is located on the side of the first light-emitting structure facing the substrate, and the second electrode is located on the side of the first light-emitting structure away from the substrate; the second light-emitting sub-pixel includes a second light-emitting structure, a third electrode and a fourth electrode, the second light-emitting structure is located in the second pixel opening, the third electrode is located on the side of the second light-emitting structure facing the substrate, and the fourth electrode is located on the side of the second light-emitting structure away from the substrate.

[0012] In addition, the orthographic projection of the second color filter on the substrate overlaps with the orthographic projection of the third electrode on the substrate. This arrangement can not only avoid the reflection of the third electrode and affect the display quality, but also minimize the area of ​​the second color filter, thereby improving the light transmittance of the display panel.

[0013] In addition, it also includes: a protective layer covering the first color filter and the second color filter, the protective layer filling the gap between adjacent second color filters to form the transparent block. The position where the graphic light shielding layer is originally set in the second display area is replaced by the protective layer to form the transparent block, thereby improving the light transmittance of the display panel.

[0014] In addition, the material of the protective layer includes one or more of acrylic oligomer, polyimide resin, epoxy resin, and polyester ink.

[0015] In addition, the second light-emitting sub-pixel includes a red light-emitting sub-pixel, a green light-emitting sub-pixel or a blue light-emitting sub-pixel; the second color filter corresponding to the red light-emitting sub-pixel has a light transmittance of greater than 90% at 590-650nm; the second color filter corresponding to the green light-emitting sub-pixel has a light transmittance of greater than 90% at 500-550nm; the second color filter corresponding to the blue light-emitting sub-pixel has a light transmittance of greater than 90% at 440-500nm. Such an arrangement can ensure the display brightness of the second display area. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0022] The first embodiment of the present invention relates to a display panel 100, such as Figure 1 , Figure 2 , Figure 3 As shown, there are a first display area 20 and a second display area 30, the light transmittance of the first display area 20 is less than the light transmittance of the second display area 30, including: first pixels, located in the first display area 20, each first pixel includes a plurality of first light-emitting sub-pixels 111 with different light-emitting colors, and a first color filter 121 is arranged on the light-emitting side of each first light-emitting sub-pixel 111; second pixels, located in the second display area 30, each second pixel includes a plurality of second light-emitting sub-pixels 112 with different light-emitting colors, and a second color filter 122 is arranged on the light-emitting side of each second light-emitting sub-pixel 112; the first color filter 121 and the second color filter 122 are in the same film layer, and space is left between adjacent second color filters 122 or a transparent block is arranged.

[0023] In actual applications, the area of ​​the first display area 20 is larger than that of the second display area 30. For example, the first display area 20 may be the main screen of the display device, and the second display area 30 may replace the “bangs area of ​​the bangs screen”.

[0024] Specifically, the display panel may further include: a protective layer 13 covering the first color filter 121 and the second color filter 122, the protective layer 13 filling the gap between adjacent second color filters 122 to form a transparent block, wherein the material of the protective layer 13 may be a transparent polymer material, for example, the material of the protective layer 13 may include one or more of acrylic oligomers, polyimide resins, epoxy resins, and polyester inks, and the position where the graphic shading layer 19 is originally set in the second display area 30 is replaced by the protective layer 13 to form a transparent block, thereby improving the light transmittance of the display panel.

[0025] In the present embodiment, the light emitting area of ​​the first light emitting sub-pixel 111 of the same light emitting color is greater than the light emitting area of ​​the second light emitting sub-pixel 112, and the first pixel arrangement structure formed by the first light emitting sub-pixel 111 is the same as the second pixel arrangement structure formed by the second light emitting sub-pixel 112. By setting the light emitting area of ​​the first light emitting sub-pixel 111 of the first display area 20 to be larger, a better display effect can be ensured. By setting the light emitting area of ​​the second light emitting sub-pixel 112 of the second display area 30 to be smaller, the light transmittance of the second display area 30 can be increased, thereby improving the imaging quality of the photosensitive device under the second display area 30.

[0026] In practical applications, the display panel may further include: a substrate 14, a device layer 15, and a pixel definition layer 16, wherein the device layer 15 is located on the substrate 14, the first pixel circuit is located on the device layer 15, the pixel definition layer 16 is located on the device layer 15, and the pixel definition layer 16 includes a first pixel opening located in the first display area 20 and a second pixel opening located in the second display area 30.

[0027] Among them, the first light-emitting sub-pixel 111 may include a first light-emitting structure 111a, a first electrode 111b and a second electrode 111c, the first light-emitting structure 111a is located in the first pixel opening, the first electrode 111b is located on the side of the first light-emitting structure 111a facing the substrate 14, and the second electrode 111c is located on the side of the first light-emitting structure 111a away from the substrate 14. The first electrode 111b can be an anode (also called Anode, generally using a three-layer structure of ITO-Ag-ITO, that is, including a first transparent conductive layer, a silver metal layer, and a second transparent conductive layer), and the second electrode 111c can be a cathode (generally using an ITO layer, that is, a transparent conductive layer), the anodes of multiple first light-emitting sub-pixels 111 are arranged at intervals from each other, and the cathodes of multiple first light-emitting sub-pixels 111 can be connected to each other to form a continuous film layer.

[0028] The second light-emitting sub-pixel 112 may include a second light-emitting structure 112a, a third electrode 112b and a fourth electrode 112c. The second light-emitting structure 112a is located in the second pixel opening, the third electrode 112b is located on the side of the second light-emitting structure 112a facing the substrate 14, and the fourth electrode 112c is located on the side of the second light-emitting structure 112a away from the substrate 14. The third electrode 112b may be an anode (also called Anode, generally using a three-layer structure of ITO-Ag-ITO, i.e., including a first transparent conductive layer, a silver metal layer, and a second transparent conductive layer), and the fourth electrode 112c may be a cathode (generally using an ITO layer, i.e., a transparent conductive layer). The anodes of the plurality of second light-emitting sub-pixels 112 are spaced apart from each other, and the cathodes of the plurality of second light-emitting sub-pixels 112 may be connected to each other to form a continuous film layer.

[0029] In this embodiment, the second light-emitting sub-pixel 112 may include a red light-emitting sub-pixel, a green light-emitting sub-pixel or a blue light-emitting sub-pixel, that is, the second light-emitting structure 112a may be a red light-emitting sub-pixel, a green light-emitting sub-pixel or a blue light-emitting sub-pixel. In fact, each second pixel may include a second light-emitting structure 112a with three different light-emitting colors: red light-emitting sub-pixel, green light-emitting sub-pixel and blue light-emitting sub-pixel. The red light-emitting sub-pixel, green light-emitting sub-pixel and blue light-emitting sub-pixel in each second pixel are arranged in a preset manner, and each second pixel serves as a repeating unit. Multiple second pixels are arranged in an array in the second display area 30.

[0030] In order to ensure the display brightness of the second display area 30, the light transmittance of the second color filter 122 corresponding to the red light-emitting sub-pixel at 590-650nm can be greater than 90%, the light transmittance of the second color filter 122 corresponding to the green light-emitting sub-pixel at 500-550nm can be greater than 90%, and the light transmittance of the second color filter 122 corresponding to the blue light-emitting sub-pixel at 440-500nm can be greater than 90%.

[0031] Similarly, the first light-emitting sub-pixel 111 may also include a red light-emitting sub-pixel, a green light-emitting sub-pixel or a blue light-emitting sub-pixel, that is, the first light-emitting structure 111a may also be a red light-emitting sub-pixel, a green light-emitting sub-pixel or a blue light-emitting sub-pixel. In fact, each first pixel may include a first light-emitting structure 111a with three different light-emitting colors: a red light-emitting sub-pixel, a green light-emitting sub-pixel and a blue light-emitting sub-pixel. The red light-emitting sub-pixel, the green light-emitting sub-pixel and the blue light-emitting sub-pixel in each first pixel are arranged in a preset manner, and each first pixel serves as a repeating unit. Multiple first pixels are arranged in an array in the first display area 20.

[0032] Optionally, the orthographic projection of the second color filter 122 on the substrate 14 and the orthographic projection of the third electrode 112b on the substrate 14 can overlap. Such a setting can not only avoid the reflection of the third electrode 112b and affect the display quality, but also minimize the area of ​​the second color filter 122, thereby improving the light transmittance of the display panel.

[0033] Here, “the orthographic projection of the second color filter 122 on the substrate 14 overlaps with the orthographic projection of the third electrode 112b on the substrate 14” means that the second color filter 122 and the third electrode 112b are exactly the same in size and position, or the second color filter 122 and the third electrode 112b are in the same position and have a small size difference.

[0034] Optional, such as Figure 1 As shown, the area of ​​the second color filter 122 can be slightly larger than the area of ​​the third electrode 112b, thereby not only ensuring that the second display area 30 has a higher light transmittance, but also enabling the second color filter 122 to filter colors better. The area of ​​the first color filter 121 can be much larger than the area of ​​the first electrode 111b, thereby isolating RGB to prevent the first display area 20 from having mixed colors in appearance.

[0035] In practical applications, the display panel may further include: an encapsulation layer 18 covering the first pixel and the second pixel, and a first color filter 121 and a second color filter 122 covering the encapsulation layer 18. Further, the encapsulation layer 18 may be a glass cover plate, or any film layer in the TFE encapsulation, that is, the first color filter 121 and the second color filter 122 may be located on the hard encapsulation, or may be located inside or above the TFE encapsulation, wherein the TFE encapsulation includes a first inorganic layer, an organic layer, and a second inorganic layer, and the encapsulation layer 18 may be any one of the first inorganic layer, the organic layer, or the second inorganic layer.

[0036] Optionally, the edges of adjacent first color filters 121 are overlapped and / or separated by a graphic shading layer 19. Such an arrangement can prevent the reflected light inside the display panel from being collected by the photosensitive device under the second display area 30 in the display device, thereby improving the imaging quality of the photosensitive device.

[0037] Among them, each first color filter 121 can be any one of a red color resist layer (only allowing red light to pass through), a green color resist layer (only allowing green light to pass through), and a blue color resist layer (only allowing blue light to pass through), and the overlapping part of adjacent first color filters 121 includes any two or three of the overlapping red color resist layer, green color resist layer, and blue color resist layer.

[0038] Since each first color filter 121 allows only one of red light, green light and blue light to pass through, for example, the red color resistance layer allows only red light to pass through, the green color resistance layer allows only green light to pass through, and the blue color resistance layer allows only blue light to pass through, the overlapping parts of adjacent first color filters 121 have a light shielding effect, thereby preventing the reflected light inside the display panel from being collected by the photosensitive device under the second display area 30 in the display device, thereby improving the imaging quality of the photosensitive device. Of course, in practical applications, adjacent first color filters 121 may not be reset, for example, adjacent first color filters 121 are just adjacent.

[0039] When the overlapping portions of adjacent first color filters 121 include three overlapping red color resist layers, green color resist layers, and blue color resist layers, the overlapping portions of adjacent first color filters 121 can better block light, thereby preventing reflected light inside the display panel from being collected by the photosensitive device under the second display area 30 in the display device, thereby improving the imaging quality of the photosensitive device.

[0040] It should be noted that the material of the "overlapping portion of adjacent first color filters 121" can be the same as or different from the material of the "portion of the first color filter 121 facing the first light-emitting sub-pixel 111", as long as it can be ensured that the overlapping portion of adjacent first color filters 121 includes at least two layers of color filter material layers that allow light of different colors to pass through. For example, the adjacent first color filters 121 are respectively a red color resist layer and a green color resist layer, and the overlapping portion can be a stack of a red color resist layer and a green color resist layer, or a stack of a red color resist layer and a blue color resist layer, or a stack of a red color resist layer, a green color resist layer, and a blue color resist layer.

[0041] Optionally, the color of the light allowed to pass through the first color filter 121 can be the same as the color of the light emitted by the corresponding first light-emitting sub-pixel 111 (i.e., the first light-emitting sub-pixel 111 located below the first color filter 121). For example, when the first light-emitting structure 111a is a red light-emitting sub-pixel, the first color filter 121 is a red color resist layer; when the first light-emitting structure 111a is a green light-emitting sub-pixel, the first color filter 121 is a green color resist layer; when the first light-emitting structure 111a is a blue light-emitting sub-pixel, the first color filter 121 is a blue color resist layer, thereby reducing the light loss of the light emitted by the first light-emitting sub-pixel 111 when passing through the first color filter 121.

[0042] It can be understood that each second color filter 122 can also be any one of a red color resist layer, a green color resist layer, and a blue color resist layer. Optionally, the color of the light allowed to pass through the second color filter 122 is the same as the color of the light emitted by the second light-emitting sub-pixel 112. For example, when the second light-emitting structure 112a is a red light-emitting sub-pixel, the second color filter 122 is a red color resist layer; when the second light-emitting structure 112a is a green light-emitting sub-pixel, the second color filter 122 is a green color resist layer; when the second light-emitting structure 112a is a blue light-emitting sub-pixel, the second color filter 122 is a blue color resist layer, thereby reducing the light loss of the light emitted by the second light-emitting sub-pixel 112 when passing through the second color filter 122.

[0043] The following is a specific description with reference to the accompanying drawings:

[0044] like Figure 2 As shown, the edges of adjacent first color filters 121 overlap and the adjacent first color filters 121 are separated by the patterned light shielding layer 19 .

[0045] Specifically, the display panel may further include: a graphic shading layer 19 located in the first display area 20 and having a through hole, the overlapping portion of adjacent first color filters 121 is located on the side of the graphic shading layer 19 away from the substrate 14, and the first color filter 121 fills the through hole, the orthographic projection of the graphic shading layer 19 on the substrate 14 is located within the orthographic projection of the pixel definition layer 16 on the substrate 14, and the overlapping portion of the adjacent first color filters 121 and the graphic shading layer 19 are used to simultaneously isolate RGB to prevent color mixing in appearance in the first display area 20.

[0046] In practical applications, the second display area 30 may not be provided with a graphic shading layer, so as to avoid the influence of the graphic shading layer on light transmission, thereby improving the light transmittance of the second display area 30 .

[0047] The patterned light shielding layer 19 may be a black matrix (BM for short). Specifically, the material of the black matrix may be chromium, chromium oxide, black resin, and the like.

[0048] like Figure 3 As shown, the display panel may also be provided with no graphic shading layer in the first display area 20 and the second display area 30. In this case, the overlapping parts of adjacent first color filters 121 are used to isolate RGB to prevent color mixing in the first display area 20.

[0049] Compared with the prior art, the embodiment of the present invention has the advantages that the first color filter 121 and the second color filter 122 are in the same film layer, and a space is left or a transparent block is set between adjacent second color filters 122, so that light can pass through the empty area or transparent block between adjacent second color filters 122 and emit out of the display panel, thereby improving the light transmittance of the second display area 30, which is beneficial to the light collection of the photosensitive device below the second display area 30 in the display device, thereby improving the imaging quality of the photosensitive device.

[0050] A second embodiment of the present invention provides a display device, such as Figure 4 As shown, it includes: a photosensitive device 200 and the display panel 100 as described above, and the photosensitive device 200 is located on a side of the second light-emitting sub-pixel away from the second color filter.

[0051] The display device may be any device with a display function, for example, a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. It may also be a non-mobile device such as a personal computer (PC), a television (TV), a teller machine, or an automated machine.

[0052] Since the second embodiment corresponds to the present embodiment, the present embodiment can be implemented in conjunction with the second embodiment. The relevant technical details mentioned in the second embodiment are still valid in the present embodiment, and the technical effects that can be achieved in the second embodiment can also be achieved in the present embodiment. In order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in the present embodiment can also be applied in the second embodiment.

[0053] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
