When used herein, the term “and / or” includes any and all combinations of the associated listed items.

[0022] In some embodiments, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a display screen provided in an embodiment of this application. The display screen 100 includes: a first display area 110 and a second display area 120; the light transmittance of the first display area 110 is greater than that of the second display area 120, and the first display area 110 includes a plurality of pixel areas distributed in an array.

[0023] The pixel region includes at least one pixel unit located within the central range of the pixel region, and a light-transmitting area set around the central range of the pixel region, wherein the central range of the pixel region is a preset range adjacent to the center of the pixel region; the light-transmitting area is used for data acquisition.

[0024] In this embodiment, the OLED (Organic Light Emitting Diode) in the display screen 100 can be formed by compression and stacking of multiple layers, including: an anode, a hole injection layer (HIL), a hole transport layer (HTL), an emission layer (EML), an electron transport layer (ETL), a cathode, and a capping layer. When an appropriate voltage is applied to the cathode and anode, electrons and holes are injected from the cathode and anode into the electron transport layer and hole transport layer, respectively. After migrating to the emission layer, they recombine to emit light, thereby realizing the self-emissive characteristic of the OLED device. Here, OLED can also be replaced with P-OLED. The essential difference between P-OLED and OLED screens lies in the slightly different materials; the former uses glass and plastic, while the latter uses only glass. Compared to OLED screens, P-OLEDs can be made thinner, have greater flexibility, lower manufacturing costs, longer lifespan, and are more resistant to drops, and also have better flexibility.

[0025] The first display area 110 can be a light-transmitting area in an organic light-emitting diode without metal wiring, and the second display area 120 can be an opaque area in an organic light-emitting diode, such as the anode or cathode.

[0026] In an alternative embodiment, please refer to Figure 2 , Figure 2 Schematic diagram of the structure of the first display area of ​​the display screen provided in the embodiments of this application Figure 1 The pixel region 111 includes at least one pixel unit 112 located within the central area of ​​the pixel region and a light-transmitting area 113 disposed around the central area of ​​the pixel region 111. Four adjacent pixel regions are clustered together to form a large pixel region 111, reducing the spacing between adjacent pixel regions. This allows both opaque pixel regions and light-transmitting areas to be concentrated, thereby increasing the area of ​​a single light-transmitting area while maintaining the overall light-transmitting area, reducing the impact of diffraction effects, and improving the imaging quality of the display screen.

[0027] It should be noted that the above embodiments are merely illustrative examples. Pixel region 111 can also be formed by two adjacent pixel regions arranged together on the left and right, or by two adjacent pixel regions arranged together on the top and bottom.

[0028] In this embodiment, in order to maximize the area of ​​a single light-transmitting area, the pixel region 111 is formed by arranging four adjacent pixel regions together.

[0029] In some embodiments, the light-transmitting area further includes light-transmitting areas between adjacent pixel units in the pixel region, and the light-transmitting areas are interconnected.

[0030] In this embodiment, there are light-transmitting areas between adjacent pixel units in the pixel region. These light-transmitting areas are connected to the light-transmitting area set around the center of the pixel region, which increases the overall area of ​​a single light-transmitting area and reduces the diffraction effect.

[0031] In some embodiments, the first display area includes a plurality of arrayed driving circuits for driving pixel units to operate; the driving circuits cover the center range of each pixel area, and the pixel units are located above the driving circuits and adjacent to the center of the pixel area.

[0032] In this embodiment, each driving circuit is connected to at least one pixel unit. The driving circuit includes an anode and a cathode stacked with the light-emitting layer, wherein the anode is located below the light-emitting layer and the cathode is located above the light-emitting layer. Here, the driving circuit is also positioned near the center of the pixel region and covers the center range of each pixel region. Alternatively, the driving circuit may extend beyond the center range of each pixel region, with the pixel unit located above the anode and below the cathode, and both the anode and cathode positioned near the center of the pixel region. This concentrates the opaque areas towards the center of the pixel region, thereby increasing the overall light transmittance and improving the image quality of the display screen.

[0033] In some embodiments, please refer to Figure 3 , Figure 3 Schematic diagram of the structure of the first display area of ​​the display screen provided in the embodiments of this application Figure 2 Pixel unit 112 includes a red sub-unit, a green sub-unit 1121 and a blue sub-unit. In each pixel unit, the green sub-unit 1121 is the furthest from the center of the pixel region.

[0034] In this embodiment, the red sub-unit is formed of red luminescent material and can emit red light; the green sub-unit is formed of green luminescent material and can emit green light; the blue sub-unit is formed of blue luminescent material and can emit blue light. Each pixel sub-unit, through the combination of the three primary colors, can enable the luminescent layer to emit light of various colors. The light-transmitting area 113 is located outside the pixel unit 112.

[0035] Since the human eye is most sensitive to green light among the three primary colors (R, G, B), and the geometric center of the three colors is closer to the green sub-unit, this embodiment distributes the four green sub-units 1121 on the outermost edge, thereby making the center of gravity of the pixel area closer to the original pixel center and ensuring image quality. Here, the positions of the red and blue sub-units are not limited; the distance between the red sub-unit and the center of the pixel area can be greater than, less than, or equal to the distance between the blue sub-unit and the center of the pixel area.

[0036] In some embodiments, the display screen further includes a mask that matches the first display area; and a cutout area of ​​the mask shared by at least two identical pixel sub-units that are closest to the center of the pixel area.

[0037] A photomask, or simply mask, is an indispensable component in the photolithography process. It carries the design pattern, and light passing through the mask projects the design onto the photoresist. The performance of the mask directly determines the quality of the photolithography process.

[0038] In this embodiment, since the cathode and anode of the pixel unit and the driving circuit are both located near the center of the pixel area, the opaque area is concentrated towards the center of the pixel area. Therefore, by setting a cutout area only at the location where the opaque area is concentrated, and by having at least two similar pixel sub-units with the smallest distance between the centers of the pixel areas share a cutout area of ​​the mask, the area of ​​the cutout area on the mask can be reduced, and the service life of the mask can be improved.

[0039] In some embodiments, at least two red sub-units share a cutout area of ​​the mask, and / or at least two blue sub-units share a cutout area of ​​the mask.

[0040] In this embodiment, the green sub-unit is the furthest from the center of the pixel region, while the red and blue sub-units are the furthest from the center of the pixel region.

[0041] In one example, the red sub-unit is the closest to the center of the pixel region.

[0042] If a pixel region is formed by four adjacent smaller pixel regions clustered together, then the red sub-units in each smaller pixel region are close to the center of the pixel region, and the four red sub-units share a single cutout area on the mask. If a pixel region is formed by two adjacent smaller pixel regions clustered together horizontally or vertically, then the two red sub-units near the center of the pixel region share a single cutout area on the mask. By ensuring that at least two red sub-units with the smallest distance between the centers of the pixel regions share a single cutout area on the mask, the area of ​​the cutout area on the mask can be reduced, thus increasing the lifespan of the mask.

[0043] In another example, the blue sub-unit is the smallest in distance from the center of the pixel region.

[0044] If a pixel region is formed by four adjacent smaller pixel regions clustered together, then the blue sub-units in each smaller pixel region are all close to the center of the pixel region, and the four blue sub-units share a single cutout area of ​​the mask. If a pixel region is formed by two adjacent smaller pixel regions clustered together on the left and right, or by two adjacent smaller pixel regions clustered together on the top and bottom, then the two blue sub-units near the center of the pixel region share a single cutout area of ​​the mask. By ensuring that at least two blue sub-units with the smallest distance between the centers of the pixel regions share a single cutout area of ​​the mask, the area of ​​the cutout area on the mask can be reduced, thus increasing the lifespan of the mask.

[0045] In another example, the distance between the red sub-unit and the center of the pixel region is equal to the distance between the blue sub-unit and the center of the pixel region. Two red sub-units and two blue sub-units share a cutout area of ​​the mask, or four red sub-units and four blue sub-units share a cutout area of ​​the mask.

[0046] In some embodiments, the mask includes a cathode mask that matches the cathode of the driving circuit and an anode mask that matches the anode of the driving circuit; the location of the cutout area of ​​the cathode mask and / or the anode mask coincides with the location of the pixel unit.

[0047] In this embodiment, since the cathode and anode of the driving circuit are both located near the center of the pixel area, the opaque area is concentrated towards the center of the pixel area. Therefore, a hollow area of ​​the cathode mask, or a hollow area of ​​the anode mask, or both a hollow area of ​​the cathode mask and a hollow area of ​​the anode mask are set at the corresponding positions, instead of using a large area of ​​overall hollow area. On the one hand, the area of ​​the hollow area on the mask can be reduced, and the service life of the mask can be improved. On the other hand, the manufacturing process of the mask is reduced, and the mask yield is improved.

[0048] In some embodiments, the signal traces within the light-transmitting area are transparent traces.

[0049] In this embodiment, the signal traces include those used in the driving circuit to connect the light-emitting layer, cathode, and anode, and these traces occupy a certain area. By using transparent traces, the overall light transmittance can be increased, the influence of diffraction effects can be reduced, and the imaging quality of the display screen can be improved.

[0050] In some embodiments, at least two pixel units in the same pixel region share the cathode and / or anode of a pixel driving circuit.

[0051] In this embodiment, at least two pixel units share the cathode of a pixel driving circuit, or share the anode of a pixel driving circuit, or share both the cathode and the anode of a pixel driving circuit, thereby significantly improving transmittance. Here, no cathode is used in the light-transmitting area; instead, the anode and / or cathode are placed only in concentrated locations in the opaque area, thus improving the transmittance of the light-transmitting area.

[0052] In one example, if a pixel region is formed by four adjacent smaller pixel regions clustered together, then the four pixel units at the center of the four adjacent pixel regions share the cathode and / or anode of a single pixel driving circuit. If a pixel region is formed by two adjacent smaller pixel regions clustered together on the left and right, or by two adjacent smaller pixel regions clustered together on the top and bottom, then the pixel units at the center of the adjacent pixel regions share the cathode and / or anode of a single pixel driving circuit.

[0053] In some embodiments, the light-transmitting areas of adjacent pixel regions are interconnected.

[0054] In this embodiment, there are light-transmitting areas between adjacent pixel units in the pixel region. These light-transmitting areas are connected to the light-transmitting area set around the center of the pixel region. In addition, the light-transmitting areas of adjacent pixel regions are interconnected, thereby further increasing the overall area of ​​the light-transmitting area, reducing the diffraction effect, and improving the imaging quality of the display screen.

[0055] This application embodiment arranges adjacent pixel units on the pixel area of ​​the display screen together, so that the opaque areas within the pixel area are concentrated together and the light-transmitting areas are connected. Thus, without changing the overall light-transmitting area, the area of ​​a single light-transmitting area is increased, the influence of diffraction effect is reduced, and the imaging quality of the display screen is improved.
