[0031] In order to make the purpose, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.
[0032] The embodiment of the present invention provides a display screen, such as figure 1 As shown, a first area 100 and a second area 200 are included. In a specific application, the first area 100 is usually used to set an under-screen photosensitive module. For example, a camera used to take pictures, a photoelectric sensor used to sense whether a person's face is close to the display screen to determine whether to turn off the display of the display screen. In a specific application, the second area 200 can generally be used to display images or implement a touch function. The second area 200 is mainly embodied as a main display area in function, and has a higher physical pixel density. The physical pixel density refers to the number of physical pixels actually prepared per unit area, not the number of pixels participating in display per unit area. The first area 100 is mainly embodied as an auxiliary display area in function, and has a lower density of physical pixels. The first area 100 is also functionally embodied as allowing light to pass through the display screen to enter the interior, so as to meet the light intensity requirement or the light sensitivity requirement of the photosensitive module under the screen. Therefore, in this embodiment, the density of physical pixels in the first area 100 is less than the density of physical pixels in the second area 200, so that light enters the interior through the display screen.
[0033] The embodiments provided in this application have at least the following effects: since the first area 100 has a lower physical pixel density, an under-screen photosensitive module can be arranged under the first area 100, so that light can penetrate through the sub-pixel gap In order to achieve higher light transmittance, at the same time to achieve full screen or full screen display.
[0034] in figure 1 In the illustrated embodiment, the second area 200 serves as the main display area of the display screen and is distributed in the middle of the display screen. The first area 100 serves as an auxiliary display area of the display screen and is distributed on the upper side of the display screen. It should be noted that the positional relationship between the first area 100 and the second area 200 can be adjusted according to actual conditions. For example, the first area 100 may be located on the left, right, or lower side of the second area 200. Alternatively, the first area 100 is distributed on the periphery of the second area 200 and surrounds the second area 200 in the middle. As long as there are two areas in the display screen that have different requirements for light intensity, it should be understood as not departing from the scope of substantial protection of the present application.
[0035] Further, in an embodiment provided in the present application, the first type of light emitting unit in the first area is different from the second type of light emitting unit in the second area;
[0036] Wherein, the first type of light-emitting unit is composed of red sub-pixels, green sub-pixels and blue sub-pixels;
[0037] The number of at least one of the red sub-pixel, the green sub-pixel, and the blue sub-pixel is different from the number of the other two sub-pixels.
[0038] In the implementation manner provided in this application, the main display area of the traditional display screen is not changed, that is, the second area 200 is not changed, but the sub-pixels of the auxiliary display area of the traditional display screen are changed, that is, The sub-pixels in the first area 100 are modified so that the first-type light-emitting units in the first area are different from the second-type light-emitting units in the second area, so that light can pass from the sub-pixel gaps in the first area. Penetration to achieve higher light transmittance, full screen or full screen display, at the same time, does not affect the work of the photosensitive module under the screen. Specifically, the number of at least one of the red sub-pixel, the green sub-pixel, and the blue sub-pixel is different from the number of the other two sub-pixels. Or it can be understood that at least one of the red sub-pixel, the green sub-pixel, and the blue sub-pixel will be shared to achieve white balance, while providing a gap for light to pass through.
[0039] Further, in an embodiment provided by the present application, the number of the first type light-emitting unit is multiple;
[0040] The number of the second type of light-emitting unit is multiple.
[0041] Active Matrix Organic Light Emitting Diode (AMOLED) is to deposit or integrate organic light emitting diode (Organic Light Emitting Diode, OLED) pixels on a TFT array. The TFT array controls the current flowing into each OLED pixel. The size, which determines the display technology of the luminous intensity of each pixel. In the embodiments provided in this application, the same driving algorithm can be used to control light emission for the first type of light-emitting unit and the second type of light-emitting unit, or different driving algorithms can be used for the first type of light-emitting unit and the second type of light-emitting unit. Glow.
[0042] In specific applications, for example, for the mobile phone display, the display part of the traditional mobile phone display is not changed, that is, multiple second-type light-emitting units are arranged, and the front camera is set for the traditional mobile phone display. Multiple first-type light-emitting units are arranged at the position. The advantage of this is that the front camera needs a certain amount of light intensity or light sensitivity to achieve good shooting results. When the front camera is arranged on the lower layer of the layered structure of the display screen, the first type of light-emitting unit is arranged. Since the first type of light-emitting units arranged in the first area share at least one of the red sub-pixels, green sub-pixels and blue sub-pixels to achieve white balance while providing a gap for light to pass through, it can meet the requirements of the under-screen photosensitive module The light intensity or light sensitivity requirements.
[0043] Further, in an embodiment provided in the present application, the first-type light-emitting units are distributed in the shape of a pair of common triangles.
[0044] Further, in an embodiment provided by the present application, the first type of light-emitting unit includes 1 red sub-pixel, 2 green sub-pixels, and 1 blue sub-pixel, and the red sub-pixel, the blue sub-pixel The color sub-pixels are located at the common edge, and the green sub-pixels are located at the other two vertices. It needs to be understood that the organic light-emitting diode OLED emits light from its source by relying on light-emitting materials. The decay rate of luminescent materials of different colors is different. Generally speaking, the decay rate of red luminescent material is the slowest among the three colors, and its luminescence life is the longest. On the other hand, green light is the most sensitive color among red, green, and blue. Therefore, reducing the number of green sub-pixels can be easily felt by the human eye. Therefore, the present invention uses the red sub-pixels and the blue sub-pixels as common pixels to avoid the effect of the common pixels on human visual perception and balance the light-emitting life of each color sub-pixel.
[0045] Please refer to figure 2 with image 3 , The first type of light emitting unit is arranged in the first area 100.

[0046] It is understandable that only the most common red sub-pixels, green sub-pixels and blue sub-pixels are used as examples here. The red sub-pixels, green sub-pixels and blue sub-pixels can also be sub-pixels of other colors. Substitute.
[0047] Further, in an embodiment provided by the present application, the first-type light-emitting units are distributed in the shape of a pair of triangles sharing a vertex.
[0048] Further, in an embodiment provided by the present application, the first type of light-emitting unit includes 1 red sub-pixel, 2 green sub-pixels, and 2 blue sub-pixels, and the red sub-pixel is located at a common vertex, The green sub-pixel and blue sub-pixel are located at the other two vertices. In this embodiment, only the red sub-pixels are used as common pixels, which can reduce the pixel density while balancing the light-emitting life of each color sub-pixel.
[0049] Please refer to Figure 4 with Figure 5 , The first type of light emitting unit is arranged in the first area 100. The light-emitting units of the first type are distributed in the shape of a pair of triangles with a common vertex. The specific structure or minimum repeating unit of the first type of light-emitting unit is detailed in Figure 5 , Including one red sub-pixel, two green sub-pixels and two blue sub-pixels, the red sub-pixel is located at a common vertex, and the green sub-pixel and the blue sub-pixel are located at the other two vertices.
[0050] It is understandable that only the most common red sub-pixels, green sub-pixels and blue sub-pixels are used as examples here. The red sub-pixels, green sub-pixels and blue sub-pixels can also be sub-pixels of other colors. Substitute.
[0051] Please refer to figure 2 with Figure 4 By sharing the red sub-pixel, the blue sub-pixel, and the red sub-pixel, respectively, white balance is achieved while providing a gap for light to pass through, so as to meet the requirements of the light intensity or light sensitivity of the under-screen photosensitive module. It is understandable that the white balance is achieved by sharing sub-pixels while providing a gap for light to pass through, and technical solutions that meet the requirements of the light intensity or light sensitivity of the photosensitive module under the screen should be understood as not departing from the essence of this application. The scope of protection.
[0052] Further, in an embodiment provided in the present application, the second type of light-emitting unit is composed of three sub-pixels, a red sub-pixel, a green sub-pixel, and a blue sub-pixel.
[0053] In the implementation manner provided by this application, the arrangement of the sub-pixels in the second type of light-emitting unit can be adaptively adjusted as required, for example, the arrangement of the sub-pixels in the first area image 3 The first type of light-emitting unit shown in, and the second area is arranged Figure 5 The first type of light-emitting unit shown in is as the second type of light-emitting unit. Of course, ordinary second-type light-emitting units can also be used, such as second-type light-emitting units having the same number of red sub-pixels, green sub-pixels, and blue sub-pixels.
[0054] In the embodiment provided in this application, the sub-pixels of the first region 100 are reduced through pixel sharing without affecting the resolution (Pixels Per Inch, PPI for short), so as to reduce the impact on the display.
[0055] Specifically, in figure 2 In the illustrated embodiment, by arranging the pixels in the first region 100 in a colateral triangle manner, 2 sub-pixels are reduced for every two light-emitting units, thereby increasing the light transmittance by at least 50%; and The density of the cells is the same as that of the second area 200, so its resolution is not affected.
[0056] Specifically, in Figure 4 In the illustrated embodiment, the sub-pixels of the first type of light-emitting unit adopt a pair of triangle shapes that share a vertex. One sub-pixel is reduced for every two light-emitting units, thereby increasing the light transmittance by at least 20%; and the density of the light-emitting units is the same as that of the second region 200, so its resolution is not affected.
