Description

Technical Field

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

[0002] OLED (Organic Light-Emitting Diode) displays are widely used due to their advantages such as self-emission, wide color gamut, low power consumption, and flexibility. To address the issues of large polarizer thickness leading to low luminous efficiency and high power consumption due to light absorption, existing OLED displays employ a Pol Less Panel (PLP) technology. This technology replaces the polarizer with a black matrix and color resist, reducing reflected light while improving the light transmittance of the OLED display. Furthermore, to achieve full-screen display, pixels and corresponding color resists are placed within the electronic component area, and holes are punched in the black matrix to ensure that the electronic component area simultaneously meets the requirements for light collection and display. However, in practical use, it has been found that the display effect in the electronic component area differs from that in other areas, resulting in poor visual quality.

[0003] Therefore, existing display devices suffer from the technical problem of different visual effects between the electronic component area and other display areas. Summary of the Invention

[0020] like Figure 1 As shown in the figure, this application embodiment provides a display panel 1, which includes a display area 101 and a non-display area 102. The display area 101 includes a first display area 101a and a second display area 101b. Both the first display area 101a and the second display area 101b can be displayed normally, and the first display area 101a and the second display area 101b may not have a clear boundary. Figure 1 To illustrate the positions of the first display area 101a and the second display area 101b, a dashed line is used to distinguish the first display area 101a and the second display area 101b. However, this dashed line does not exist in actual use.

[0021] like Figure 1 As shown, the non-display area 102 includes a left border area, a right border area, a top border area, and a bottom border area surrounding the display area 101. It is understood that the embodiments of this application are not limited to this. The non-display area 102 may include border areas disposed on one side, two sides, three sides, and four sides of the display area 101, and the non-display area 102 may be disposed on the back of the display panel by bending or folding.

[0022] Specifically, such as Figure 2, Figure 3 As shown, the display panel 1 includes a substrate 11, a driving circuit layer 12, a light-emitting functional layer, an encapsulation layer 14, a touch layer 15, a black matrix layer 16, and a color resist layer 17.

[0023] Specifically, to illustrate the specific design of the driving circuit layer 12 in the embodiments of this application, a detailed description of the film structure of the driving circuit layer 12 is provided. It should be understood that the film structure of the driving circuit layer 12 is not limited thereto. The driving circuit layer 12 may include an active layer, a first gate insulating layer, a first gate layer, a second gate insulating layer, a second gate layer, an interlayer insulating layer, a first source-drain layer, a first planarization layer, a second source-drain layer, and a second planarization layer, which are sequentially disposed.

[0024] Specifically, the active layer material can be silicon semiconductor, specifically low-temperature polycrystalline silicon, or the active layer material can be oxide semiconductor, specifically metal oxide semiconductor, such as indium gallium zinc oxide.

[0025] Specifically, the driving circuit layer 12 may also include a buffer layer, which may be disposed between the substrate 11 and the active layer.

[0026] Specifically, the above embodiment is illustrated by taking the driving circuit layer 12 as having two source-drain layers as an example. However, the embodiments of this application are not limited to this. The driving circuit layer 12 may include one source-drain layer or three source-drain layers, and a corresponding planarization layer may be provided accordingly.

[0027] Specifically, the above embodiment is described using the example of the driving circuit layer 12 including an active layer. However, the embodiments of this application are not limited to this. The driving circuit layer 12 can include an active layer and a semiconductor layer, with one of the active layer and the semiconductor layer being made of silicon semiconductor and the other being made of oxide semiconductor. Corresponding gate layers are provided to form different types of thin film transistors.

[0028] Specifically, the light-emitting functional layer may include a pixel electrode layer 131, a pixel definition layer 132, a light-emitting material layer 133, and a common electrode layer 134. The light-emitting functional layer may also include support pillars.

[0029] Specifically, the pixel definition layer includes a first sub-layer 132a and a second sub-layer 132b. The material of the first sub-layer 132a can be a photoresist doped with black pigment, and the material of the second sub-layer 132b can be a photoresist without black pigment, thereby reducing the reflectivity of the display panel.

[0030] Specifically, the light-emitting material layer can include a hole layer, an electron layer, and a light-emitting layer. The light-emitting materials corresponding to different light-emitting parts in the light-emitting layer can be different or the same. The light emitted by the light-emitting material layer can be white light, or it can be red light, green light, or blue light. For example, a stacked device can be set in the pixel opening defined by the pixel definition layer so that the light-emitting layer includes a red light-emitting layer, a green light-emitting layer, and a blue light-emitting layer. The red light-emitting layer, the green light-emitting layer, and the blue light-emitting layer are stacked so that each light-emitting part emits white light. Alternatively, the red light-emitting layer, the green light-emitting layer, and the blue light-emitting layer can be set in the light-emitting areas of the red sub-pixel, the green sub-pixel, and the blue sub-pixel, respectively, so that the light-emitting color of the light-emitting layer corresponding to different sub-pixels is different. Each sub-pixel can also use a stacked device, that is, improve the display effect by using multiple light-emitting layers and charge generation layers. For example, two red light-emitting layers can be set in the light-emitting area corresponding to the red sub-pixel.

[0031] Specifically, the encapsulation layer 14 may include a first inorganic layer, an organic layer, and a second inorganic layer.

[0032] Specifically, the touch layer 15 may include a first touch insulating layer, a first touch metal layer, a second touch insulating layer, and a second touch metal layer.

[0033] like Figures 1 to 5 As shown, this application embodiment provides a display panel 1, which includes a first display area 101a and a second display area 101b corresponding to the positions of electronic components. Both the first display area 101a and the second display area 101b are provided with a plurality of sub-pixel units 21. The display panel 1 includes a substrate 11 and a black matrix layer 16. The black matrix layer 16 is disposed on one side of the substrate 11. The black matrix layer 16 is provided with a first type of opening 32 and a second type of opening 31. The first type of opening 32 is correspondingly disposed to the sub-pixel units 21. The second type of opening 31 is disposed in the second display area 101b and is located in the area between the plurality of sub-pixel units 21. The second type of opening 31 is provided with an anti-reflective part 33.

[0034] This application provides a display panel 1. The display panel 1 has a black matrix layer 16 with a first type of opening 32 and a second type of opening 31. The first type of opening 32 is correspondingly arranged with the sub-pixel unit 21, so that the sub-pixel unit 21 can emit light normally. The second type of opening 31 is arranged in the second display area 101b and in the area between multiple sub-pixel units 21. Light can be collected through the second type of opening 31 to realize the normal function of electronic components. Furthermore, an anti-reflection part 33 is provided in the second type of opening 31 to avoid the problem of different visual effects in different areas due to excessive reflectivity at the second type of opening 31, thereby improving the display effect of the display panel.

[0035] Specifically, compared to some display devices where holes are cut into the black matrix layer 16 to allow light to pass through and for electronic components to receive light, the openings are filled with light-transmitting material. However, there are metal traces or electrodes beneath the black matrix layer, resulting in high reflectivity at the openings. In the normal display area, since light is not required, no openings are made in the black matrix layer. This causes the reflectivity of the display area with electronic components to differ from other display areas, resulting in a noticeable difference in visual effect. In this embodiment, by incorporating an anti-reflective part 33 within the second type of opening 31, the reflectivity at the second type of opening 31 can be reduced, thereby lowering the reflectivity within the second display area 101b, reducing the visual difference between the first display area 101a and the second display area 101b, and improving the display effect of the display panel.

[0036] In some embodiments, the display panel 1 further includes a color resist layer 17, which includes the anti-reflective portion 33. By including the anti-reflective portion in the color resist layer, the color resist layer can reduce the reflectivity at the second type of opening 31, thereby reducing the visual difference between the first display area 101a and the second display area 101b. Furthermore, the anti-reflective portion 33 can be formed simultaneously with the color resist layer, eliminating the need for additional processing steps in the display panel and improving the manufacturing efficiency of the display panel.

[0037] Specifically, taking an infrared light sensor as an example, the color resist layer 17 may include a first color resist layer 171, a second color resist layer 172, and a third color resist layer 173. Since the color resist layer 17 can transmit infrared light, one, two, or all three of the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 may include an anti-reflection part 33.

[0038] In some embodiments, such as Figures 2 to 5As shown, the color resist layer 17 includes a first color resist layer 171, a second color resist layer 172, and a third color resist layer 173 with different light-transmitting colors. The anti-reflective part 33 includes a first part 331 disposed in the first color resist layer 171, a second part 332 disposed in the second color resist layer 172, and a third part 333 disposed in the third color resist layer 173. The second type of opening 31 includes a first through hole 301, a second through hole 302, and a third through hole 303. The first part 331 is disposed in the first through hole 301, the second part 332 is disposed in the second through hole 302, and the third part 3333 is disposed in the third through hole 303. By including a first portion 331 disposed on a first color resist layer 171, a second portion 332 disposed on a second color resist layer 172, and a third portion 333 disposed on a third color resist layer 173, the anti-reflection portion 33 can be formed using the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173. After light shines on the first portion 331, the second portion 332, and the third portion 333 and is reflected, the three can mix to form white light, making the reflected light similar to or even the same as the reflected light of the sub-pixel area, thereby reducing visual difference.

[0039] Specifically, it is understood that metal traces or electrodes are also set within the setting area of ​​the sub-pixel unit. For example, the common electrode layer is set across the entire surface, whether in the setting area of ​​the sub-pixel unit or in the area between the sub-pixel units. When external light shines on the display panel, some light will also pass through the color resist in the sub-pixel area and shine on the common electrode layer for reflection. In this embodiment, the second type of opening is filled with color resist, so that when light passes through the color resist and shines on the common electrode layer for reflection, the reflected light in the sub-pixel area is similar to or even the same as the reflected light at the second type of opening in the black matrix layer, thereby reducing the visual difference.

[0040] Specifically, it can be understood that regardless of whether the electronic component collects visible light or infrared light, since the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 transmit different colors of light, the first part 331, the second part 332, and the third part 333 can transmit various colors of light, thereby enabling the normal function of the electronic component.

[0041] In some embodiments, such as Figures 2 to 5As shown, the plurality of sub-pixel units 21 include a first sub-pixel 201, a second sub-pixel 202, and a third sub-pixel 203 of different emitting colors. The first color resist layer 171 includes a first color resist portion 171a corresponding to the first sub-pixel 201, the second color resist layer 172 includes a second color resist portion 172a corresponding to the second sub-pixel 202, and the third color resist layer 173 includes a third color resist portion 173a corresponding to the third sub-pixel 203. By including a first color resist portion 171a corresponding to the first sub-pixel 201 in the first color resist layer 171, a second color resist portion 172a corresponding to the second sub-pixel 202 in the second color resist layer 172, and a third color resist portion 173a corresponding to the third sub-pixel 203 in the third color resist layer 173, each color resist portion can improve the color purity of each sub-pixel, thereby improving the display effect of the display panel.

[0042] Specifically, the first color resist portion 171a, the second color resist portion 172a, and the third color resist portion 173a are disposed within the first type of opening 32.

[0043] Specifically, compared to the problems of low light utilization and large display panel thickness caused by setting a polarizer, the embodiments of this application improve the light utilization and reduce the thickness by setting a color resist layer.

[0044] In some embodiments, such as Figure 5 As shown, the plurality of sub-pixel units 21 include a first sub-pixel 201, a second sub-pixel 202, and a third sub-pixel 203 of different emitting colors; wherein, the area ratio of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 is the same as the opening area ratio of the first through hole 301, the second through hole 302, and the third through hole 303. By making the opening area ratio of the first through hole 301, the second through hole 302, and the third through hole 303 equal to the area ratio of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203, and making the area ratio of the first part 331, the second part 332, and the third part 333 equal to the area ratio of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203, when the film layer in the corresponding areas of the first part 331, the second part 332, and the third part 333 reflects light, the light synthesized after the reflected light passes through the first part 331, the second part 332, and the third part 333 is similar to or even the same as the light synthesized after passing through the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203, thereby reducing the visual difference and improving the display effect of the display panel.

[0045] Specifically, in some display devices, when forming openings in the black matrix layer, the areas of each opening are equal, while the areas of different sub-pixel units are often unequal. This results in a difference in chromaticity between the reflected light from the opening area and the reflected light from the sub-pixel area, leading to a significant difference between the reflected light from the sub-pixel area and the reflected light from the opening area of ​​the black matrix layer. During display, the difference between the first display area and the second display area is clearly visible, resulting in a visual difference. This embodiment of the application reduces the visual difference by making the opening area ratio of the first through-hole 301, the second through-hole 302, and the third through-hole 303 equal to the area ratio of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203. This minimizes or even eliminates the difference between the reflected light from the sub-pixel area and the reflected light from the opening area of ​​the black matrix layer.

[0046] Specifically, it can be understood that the area ratio of the first sub-pixel, the second sub-pixel, and the third sub-pixel refers to the area of ​​the first sub-pixel: the area of ​​the second sub-pixel: the area of ​​the third sub-pixel. Specifically, it can be the area of ​​a single first sub-pixel: the area of ​​a single second sub-pixel: the area of ​​a single third sub-pixel. The area ratio of the first sub-pixel, the second sub-pixel, and the third sub-pixel can be equal to the opening area ratio of the openings of the corresponding different sub-pixels in the pixel definition layer, or equal to the area ratio of the color resist portion corresponding to each sub-pixel unit.

[0047] Specifically, such as Figure 2 , Figure 3 As shown, the pixel definition layer 132 has pixel openings, and light-emitting material is filled inside the pixel openings to achieve light emission. By controlling the size of the pixel openings, the area of ​​the sub-pixel unit can be controlled. Therefore, the area ratio of the first sub-pixel, the second sub-pixel, and the third sub-pixel can be equal to the opening area ratio of the pixel definition layer corresponding to the first sub-pixel, the pixel definition layer corresponding to the second sub-pixel, and the pixel definition layer corresponding to the third sub-pixel.

[0048] Specifically, the ratio of the opening areas of the first through hole 301, the second through hole 302, and the third through hole 303 refers to the ratio of the opening area of ​​the first through hole 301 to the opening area of ​​the second through hole 302 to the opening area of ​​the third through hole 303. More specifically, it can be the ratio of the opening area of ​​a single first through hole 301 to the opening area of ​​a single second through hole 302 to the opening area of ​​a single third through hole 303. Since the first through hole 301, the second through hole 302, and the third through hole 303 are respectively provided with a first part 331, a second part 332, and a third part 333, the ratio of the opening areas of the first through hole 301, the second through hole 302, and the third through hole 303 can be equal to the ratio of the areas of the first part 331, the second part 332, and the third part 333.

[0049] For example, if the area ratio of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 is 1.5:1:2, then the opening area ratio of the first through hole 301, the second through hole 302, and the third through hole 303 can be 1.5:1:2.

[0050] In some embodiments, the areas of any two of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 are not equal, and the areas of any two of the first through-hole 301, the second through-hole 302, and the third through-hole 303 are not equal.

[0051] Specifically, such as Figures 2 to 3 As shown, the light-emitting material layer 133 includes a first light-emitting part, a second light-emitting part, and a third light-emitting part corresponding to the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203, respectively. The first light-emitting part, the second light-emitting part, and the third light-emitting part emit different colors and use different light-emitting materials, resulting in different luminous efficiencies. To make the efficiencies of each light-emitting part similar and improve display uniformity, the areas of each sub-pixel unit are made different. To make the reflected light of the setting area of ​​the sub-pixel unit consistent with the reflected light of the setting area of ​​the second type of opening in the black matrix layer, the areas of each through-hole can be made unequal, thereby reducing visual difference.

[0052] In some embodiments, such as Figure 3 As shown, the area of ​​the first sub-pixel 201 is larger than the area of ​​the second sub-pixel 202, and the area of ​​the first sub-pixel 201 is smaller than the area of ​​the third sub-pixel 203; wherein, the opening area of ​​the first through hole 301 is larger than the opening area of ​​the second through hole 302, and the opening area of ​​the first through hole 301 is smaller than the opening area of ​​the third through hole 303. By making the area of ​​the first sub-pixel 201 larger than the area of ​​the second sub-pixel 202, and the area of ​​the first sub-pixel 201 smaller than the area of ​​the third sub-pixel 203, the luminous efficiency of each sub-pixel is made close or even the same, improving display uniformity. Furthermore, by making the opening area of ​​the first through-hole 301 larger than the opening area of ​​the second through-hole 302, and the opening area of ​​the first through-hole 301 smaller than the opening area of ​​the third through-hole 303, the area ratio of the first part 331, the second part 332, and the third part 333 is the same as the area ratio of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203. This makes the reflected light of the setting area of ​​the sub-pixel unit consistent with the reflected light of the setting area of ​​the second type of opening in the black matrix layer, thereby reducing visual difference.

[0053] Specifically, the shape of the first through hole 301 can be the same as the shape of the first sub-pixel 201; the shape of the second through hole 302 can be the same as the shape of the second sub-pixel 202; and the shape of the third through hole 303 can be the same as the shape of the third sub-pixel 203.

[0054] Specifically, taking the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 as examples where the shapes are all circular, the diameters of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 can be 15 micrometers, 10 micrometers, and 20 micrometers, respectively. Correspondingly, the shapes of the first through hole 301, the second through hole 302, and the third through hole 303 can be circular, and the diameters of the first through hole 301, the second through hole 302, and the third through hole 303 can be 10 micrometers, 6.7 micrometers, and 12 micrometers, respectively.

[0055] In some embodiments, such as Figures 2 to 5 As shown, the area of ​​the first sub-pixel 201 is larger than the area of ​​the first through-hole 301, the area of ​​the second sub-pixel 202 is larger than the area of ​​the second through-hole 302, and the area of ​​the third sub-pixel 203 is larger than the area of ​​the third through-hole 303. By making the area of ​​the first sub-pixel 201 larger than the area of ​​the first through-hole 301, the area of ​​the second sub-pixel 202 larger than the area of ​​the second through-hole 302, and the area of ​​the third sub-pixel 203 larger than the area of ​​the third through-hole 303, the normal display of the display panel is not affected when the second type of opening 31 is set.

[0056] Specifically, it is understandable that in the design process of the display panel, the spacing between the color resists corresponding to the sub-pixel units is generally smaller than the diameter of the largest sub-pixel. The second type of opening 31 is set between the sub-pixel units, so the area of ​​the second type of opening 31 can be smaller than the area of ​​the corresponding sub-pixel unit.

[0057] For example, if the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 are all circular, their diameters can be 15 micrometers, 10 micrometers, and 20 micrometers, respectively. The width of the black matrix layer is generally less than 20 micrometers. Therefore, when the second type of opening 31 is formed in the black matrix layer, the diameter of the second type of opening 31 needs to be less than 20 micrometers. At the same time, in order to keep the area ratio of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 the same as the opening area ratio of the first through hole 301, the second through hole 302, and the third through hole 303, the diameters of the first through hole 301, the second through hole 302, and the third through hole 303 can be 10 micrometers, 6.7 micrometers, and 12 micrometers, respectively.

[0058] In some embodiments, such as Figure 5As shown, the ratio of the number of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 is the same as the ratio of the number of the first through-hole 301, the second through-hole 302, and the third through-hole 303. By making the ratio of the number of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 the same as the ratio of the number of the first through-hole 301, the second through-hole 302, and the third through-hole 303, the light synthesized after the reflected light passes through the first part 331, the second part 332, and the third part 333 is similar to or even the same as the light synthesized after passing through the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203, thereby reducing the parallax and improving the display effect of the display panel.

[0059] Specifically, such as Figure 5 As shown, taking a repeating unit 22 as an example, a repeating unit 22 includes four quarter-sized third sub-pixels 203, one complete third sub-pixel 203, four second sub-pixels 202, and four half-sized first sub-pixels 201. That is, a repeating unit 22 includes two first sub-pixels 201, two third sub-pixels 203, and four second sub-pixels 202. The ratio of the number of first sub-pixels 201, second sub-pixels 202, and third sub-pixels 203 is 1:2:1. At this time, the ratio of the number of first through-holes 301, second through-holes 302, and third through-holes 303 can also be 1:2:1, for example... Figure 5 In this configuration, a repeating unit 22 contains two half-third through holes 303, one complete third through hole 303, two half-first through holes 301, one complete first through hole 301, four half-second through holes 302, and two complete second through holes 302. That is, a repeating unit 22 contains two first through holes 301, two third through holes 303, and four second through holes 302, meaning the ratio of the number of first through holes 301, second through holes 302, and third through holes 303 is 1:2:1.

[0060] Specifically, the number of first through holes 301 can be equal to the number of first sub-pixels 201, the number of second through holes 302 can be equal to the number of second sub-pixels 202, and the number of third through holes 303 can be equal to the number of third sub-pixels 203; however, the embodiments of this application are not limited to this, for example, the number of first through holes 301 can be less than the number of first sub-pixels 201, the number of second through holes 302 can be less than the number of second sub-pixels 202, and the number of third through holes 303 can be less than the number of third sub-pixels 203.

[0061] In some embodiments, such as Figure 4 , Figure 5As shown, the first sub-pixel 201 and the third sub-pixel 203 are alternately arranged along the first direction X to form a first sub-pixel row 231, and a plurality of second sub-pixels 202 are spaced apart along the first direction X to form a second sub-pixel row 232. The first sub-pixel 201 and the third sub-pixel 203 are alternately arranged along the second direction Y to form a first sub-pixel column 241, and a plurality of second sub-pixels 202 are spaced apart along the second direction Y to form a second sub-pixel column 242. The angle between the first direction X and the second direction Y is greater than 0 and less than or equal to 90 degrees.

[0062] In some embodiments, such as Figure 5 As shown, the second through hole 302 is disposed between the first sub-pixel 201 and the third sub-pixel 203 in the first sub-pixel column 241, and the second through hole 302 is disposed between a plurality of second sub-pixels 202 in the second sub-pixel row 232; The first through-hole 301 and the third through-hole 303 are alternately disposed between the first sub-pixel 201 and the third sub-pixel 203 in the first sub-pixel row 231, and the first through-hole 301 and the third through-hole 303 are alternately disposed between multiple second sub-pixels 202 in the second sub-pixel column 242; so that the light synthesized after the reflected light passes through the first part 331, the second part 332 and the third part 333 is similar to or even the same as the light synthesized after passing through the first sub-pixel 201, the second sub-pixel 202 and the third sub-pixel 203, thereby reducing the visual difference and improving the display effect of the display panel.

[0063] Specifically, in the first sub-pixel row 231, the first through-hole 301 is located to the right of the first sub-pixel 201, and the third through-hole 303 is located to the right of the third sub-pixel 203; or in the first sub-pixel row 231, the first through-hole 301 is located to the left of the first sub-pixel 201, and the third through-hole 303 is located to the left of the third sub-pixel 203.

[0064] Specifically, the center of the second through hole 302 located in the first sub-pixel column 241 can be on the same straight line as the center of the first sub-pixel 201 and the third sub-pixel 203 in the first sub-pixel column 241, and the center of the second through hole 302 located in the sub-pixel row 232 can be on the same straight line as the center of multiple second sub-pixels 202 in the second sub-pixel row 232.

[0065] Specifically, the centers of the first through hole 301 and the third through hole 303 located in the first sub-pixel row 231 can be on the same straight line as the centers of the first sub-pixel 201 and the third sub-pixel 203 located in the first sub-pixel row 231, and the centers of the first through hole 301 and the third through hole 303 located in the second sub-pixel column 242 can be on the same straight line as the centers of the multiple second sub-pixels 202 in the second sub-pixel column 242.

[0066] In some embodiments, the second through hole 302 is disposed between the first sub-pixel 201 and the third sub-pixel 203 in the first sub-pixel column 241, and the second through hole 302 is disposed between the first sub-pixel 201 and the third sub-pixel 203 in the first sub-pixel row 231; The first through hole 301 and the third through hole 303 are alternately disposed between multiple second sub-pixels 202 in the second sub-pixel row 232, and the first through hole 301 and the third through hole 303 are alternately disposed between multiple second sub-pixels 202 in the second sub-pixel column 242.

[0067] In some embodiments, the second through hole 302 is disposed between a plurality of second sub-pixels 202 in the second sub-pixel column 242, and the second through hole 302 is disposed between the first sub-pixel 201 and the third sub-pixel 203 in the first sub-pixel row 231; The first through hole 301 and the third through hole 303 are alternately disposed between a plurality of second sub-pixels 202 in the second sub-pixel row 232, and the first through hole 301 and the third through hole 303 are alternately disposed between the first sub-pixel 201 and the third sub-pixel 203 in the first sub-pixel column 241.

[0068] In some embodiments, such as Figures 2 to 5 As shown, the display panel 1 further includes a pixel definition layer 132, which includes a first sub-layer 132a and a second sub-layer 132b. The light transmittance of the second sub-layer 132b is greater than that of the first sub-layer 132a. The second sub-layer 132b is disposed on the side of the first sub-layer 132a away from the substrate 11. The first sub-layer 132a has a first via 341, a second via 342, and a third via 343 respectively in the regions corresponding to the first via 301, the second via 302, and the third via 303. The second sub-layer 132b fills the first via 341, the second via 342, and the third via 343. The opening area ratio of the first via 341, the second via 342, and the third via 343 is the same as the opening area ratio of the first through hole 301, the second through hole 302, and the third through hole 303. By making the opening area ratio of the first via 341, the second via 342, and the third via 343 the same as the opening area ratio of the first through hole 301, the second through hole 302, and the third through hole 303, the light reflected from the second type of opening in the black matrix layer is similar to or even the same as the light reflected from the setting area of ​​the sub-pixel unit, thus reducing visual difference.

[0069] Specifically, the opening area of ​​the opening corresponding to the sub-pixel unit in the pixel definition layer can be less than or equal to the opening area of ​​the first type of opening 32. Specifically, the opening area of ​​the opening corresponding to the first sub-pixel in the pixel definition layer can be less than the opening area of ​​the opening corresponding to the first color resist in the first type of opening 32, the opening area of ​​the opening corresponding to the second sub-pixel in the pixel definition layer can be less than the opening area of ​​the opening corresponding to the second color resist in the first type of opening 32, and the opening area of ​​the opening corresponding to the third sub-pixel in the pixel definition layer can be less than the opening area of ​​the opening corresponding to the third color resist in the first type of opening 32. Furthermore, the ratio of the opening areas of the openings corresponding to the first sub-pixel, the second sub-pixel, and the third sub-pixel in the pixel definition layer can be equal to the ratio of the opening areas of the openings corresponding to the first color resist, the second color resist, and the third color resist in the first type of opening 32.

[0070] Specifically, the opening area of ​​the region between corresponding sub-pixel units in the pixel definition layer can be greater than or equal to the opening area of ​​the first type of opening 32, that is, the opening areas of the first via 341, the second via 342, and the third via 343 are respectively greater than or equal to the opening areas of the first through hole 301, the second through hole 302, and the third through hole 303. However, the embodiments of this application are not limited to this, and the opening areas of the first via 341, the second via 342, and the third via 343 can be smaller than the opening areas of the first through hole 301, the second through hole 302, and the third through hole 303.

[0071] Specifically, the emission colors of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 can be red, green, and blue, respectively; or the emission colors of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 can be red, blue, and green, respectively; or the emission colors of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 can be green, blue, and red, respectively; or the emission colors of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 can be blue, red, and green, respectively; or the emission colors of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 can be blue, green, and red, respectively.

[0072] Specifically, such as Figure 2 , Figure 3 As shown, in the first display area 101a, the first sub-layer 132a does not form vias in the area between the setting areas of the corresponding sub-pixel units, and the black matrix layer 16 does not form vias in the area between the setting areas of the corresponding sub-pixel units; in the second display area 101b, the first sub-layer 132a forms vias in the area between the setting areas of the corresponding sub-pixel units, and the black matrix layer 16 forms vias in the area between the setting areas of the corresponding sub-pixel units.

[0073] Specifically, the thickness of the first part 331 can be equal to the thickness of the first color resist layer 171; the thickness of the second part 332 can be equal to the thickness of the second color resist layer 172; and the thickness of the third part 333 can be equal to the thickness of the third color resist layer 173.

[0074] Specifically, such as Figure 4 , Figure 5 As shown, in the first display area 101a, there are no through holes between each sub-pixel unit, while in the second display area 101b, at least some sub-pixel units are provided with through holes.

[0075] Specifically, such as Figure 4 , Figure 5 As shown, the spacing between each sub-pixel unit in the first display area 101a is equal to the spacing between the corresponding sub-pixel units in the second display area 101b.

[0076] For example, if the spacing between the first sub-pixel 201 and the second sub-pixel 202 in the first display area 101a is 18 micrometers, then the spacing between the first sub-pixel 201 and the second sub-pixel 202 in the second display area 101b is also 18 micrometers.

[0077] Specifically, the light-transmitting colors of the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 are the same as the light-emitting colors of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203, respectively. For example, the light-transmitting colors of the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 are red, green, and blue, respectively; or the light-transmitting colors of the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 are red, blue, and green, respectively; or the light-transmitting colors of the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 are green, blue, and red, respectively; or the light-transmitting colors of the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 are blue, red, and green, respectively; or the light-transmitting colors of the first color resist layer 171, the second color resist layer 172, and the third color resist layer 173 are blue, green, and red, respectively.

[0078] like Figure 6 As shown, Figure 6 The horizontal axis represents the wavelength of light in nanometers, and the vertical axis represents the transmittance. Curve 1 shows the transmittance of a red color resist for different wavelengths of light, curve 2 shows the transmittance of a green color resist for different wavelengths of light, and curve 3 shows the transmittance of a blue color resist for different wavelengths of light.

[0079] Specifically, the above embodiments have provided a detailed description of the display panel from aspects such as the film layer structure and pixel arrangement. It is understood that when there is no conflict between the embodiments, the embodiments can be combined. For example, the ratio of the number of the first sub-pixel, the second sub-pixel, and the third sub-pixel is the same as the ratio of the number of the first through hole, the second through hole, and the third through hole, and the area ratio of the first sub-pixel, the second sub-pixel, and the third sub-pixel is the same as the opening area ratio of the first through hole, the second through hole, and the third through hole.
