Abstract
Description
Technical Field
[0001] This utility model relates to the field of display technology, and in particular to a display pixel structure and a display screen. Background Technology
[0002] OLED (Organic Light Emitting Diode) technology has become a leading technology in modern displays due to its superior display performance and flexibility. With continuous advancements in display technology, OLEDs, with their advantages of self-illumination, high contrast, wide viewing angle, fast response time, thinness, lightness, and low power consumption, have been widely adopted in the displays of smartphones, televisions, tablets, and other electronic devices. Within the display industry, different pixel designs result in different display effects and lifespans. OLED manufacturers continuously update pixel designs to improve display performance and lifespan. For example, in traditional pixel structures, the luminous area of the blue sub-pixel is the same as that of the red sub-pixel, but the blue sub-pixel occupies a smaller proportion of the pixel unit. Since the luminous efficiency of the blue OLED material is relatively low, a larger driving current is required to achieve the same brightness as other sub-pixels. However, this leads to a shorter lifespan for the blue sub-pixel, consequently reducing the display's performance and lifespan.
[0003] In view of the above, a novel display pixel structure is proposed, which can improve the display effect and service life of the display screen. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display screen pixel structure that can improve the display effect and service life of the display screen.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A display screen pixel structure includes: a plurality of pixel units arranged in a row, each pixel unit including a red sub-pixel, a blue sub-pixel and two green sub-pixels, the pixel unit formed by the arrangement of the red sub-pixel, the blue sub-pixel and the two green sub-pixels forming a rhombic structure; the blue sub-pixel has a rhombic structure, the light-emitting area of the blue sub-pixel is larger than the light-emitting area of the red sub-pixel, and the diagonal length of the blue sub-pixel is greater than or equal to 50% of the diagonal length of the pixel unit.
[0007] In one embodiment, the red sub-pixel has a diamond-shaped structure, and the center of the red sub-pixel is on the same horizontal plane as the center of the blue sub-pixel.
[0008] In one embodiment, the green sub-pixel has a rectangular structure.
[0009] In one embodiment, the four corners of the green sub-pixel are rounded.
[0010] In one embodiment, the four rounded chamfers on the green sub-pixel are equal.
[0011] In one embodiment, the longer side of the green sub-pixel is smaller than the side size of the blue sub-pixel, and the shorter side of the green sub-pixel is smaller than the side size of the red sub-pixel.
[0012] In one embodiment, the two green sub-pixels are arranged in a mirror-symmetric manner along the diagonal of the pixel unit.
[0013] In one embodiment, the distance between the two green sub-pixels and the blue sub-pixel is equal.
[0014] In one embodiment, the distance between the two green sub-pixels and the red sub-pixel is equal.
[0015] A display screen comprising the display screen pixel structure described above.
[0016] Compared with the prior art, the present invention has at least the following advantages:
[0017] This invention relates to a display pixel structure that arranges blue sub-pixels, red sub-pixels, and two green sub-pixels into a rhomboid pixel unit. The light-emitting area of the blue sub-pixels is larger than that of the red sub-pixels, and the diagonal length of the blue sub-pixels is greater than or equal to 50% of the diagonal length of the pixel unit. This increases the light-emitting area of the blue sub-pixels, addressing the problem that the relatively low luminous efficiency of OLED blue light-emitting materials requires a larger driving current to achieve the same brightness as other sub-pixels, resulting in a shorter lifespan for blue sub-pixels. By increasing the light-emitting area of the blue sub-pixels and their proportion within the pixel unit, this invention ensures both brightness and lifespan of the blue sub-pixels while reducing the driving current, thereby improving both the display effect and the lifespan of the display. Attached Figure Description
[0018] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.
[0019] Figure 1 This is a schematic diagram of the display pixel structure in one embodiment of the present invention;
[0020] Figure 2 for Figure 1 A schematic diagram of the pixel unit structure of the display screen pixel structure; Detailed Implementation
[0021] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.
[0022] Please see Figure 1 and Figure 2 As shown, a display screen pixel structure includes: a plurality of pixel units 100 arranged in a row, each pixel unit 100 including a red sub-pixel 110, a blue sub-pixel 120 and two green sub-pixels 130, the pixel unit 100 formed by the arrangement of the red sub-pixel 110, the blue sub-pixel 120 and the two green sub-pixels 130 is in a rhomboid structure; the blue sub-pixel 120 is in a rhomboid structure, the light-emitting area of the blue sub-pixel 120 is larger than the light-emitting area of the red sub-pixel 110, and the diagonal length of the blue sub-pixel 120 is greater than or equal to 50% of the diagonal length of the pixel unit 100.
[0023] It should be noted that in traditional pixel structures, the light-emitting area of the blue sub-pixel 120 is the same as that of the red sub-pixel 110, and the blue sub-pixel 120 occupies a relatively small proportion in pixel unit 100. Since the luminous efficiency of OLED blue light-emitting material is relatively low, a larger driving current is required to achieve the same brightness as other sub-pixels. However, this results in a shorter lifespan for the blue sub-pixel 120, leading to a decrease in display quality and lifespan. Therefore, in this invention, the light-emitting area of the blue sub-pixel 120 is made larger than that of the red sub-pixel 110, and the diagonal length of the blue sub-pixel 120 is greater than or equal to 50% of the diagonal length of pixel unit 100, thereby increasing the proportion of the blue sub-pixel 120 in pixel unit 100. This eliminates the need for a larger driving current, thus ensuring both the brightness and lifespan of the blue sub-pixel 120 while reducing the driving current. This improves the display quality and lifespan of the screen. For example, in this embodiment, the diagonal length of the blue sub-pixel 120 is 50%-60% of the diagonal length of the entire pixel unit 100. It should also be noted that each pixel unit 100 can be arranged in a certain number in the X and Y directions according to the resolution requirements of the actual display screen.
[0024] In one embodiment, the red sub-pixel 110 has a rhomboid structure, and the center of the red sub-pixel 110 and the center of the blue sub-pixel 120 are on the same horizontal plane. Furthermore, the centers of both the red sub-pixel 110 and the blue sub-pixel 120 are located on the diagonal of the complete pixel unit 100 in the X direction. This ensures uniform light distribution in the red and blue sub-pixels 110 and avoids color deviation.
[0025] Preferably, the green sub-pixel 130 has a rectangular structure. More preferably, the four corners of the green sub-pixel 130 are rounded. In this embodiment, the four rounded corners on the green sub-pixel 130 are equal; thus, equal rounded corners ensure uniform light distribution and improve display performance.
[0026] Since there are two green sub-pixels 130, to avoid the green sub-pixels 130 becoming too large, resulting in too much light-emitting area and affecting the display effect, in one embodiment, the longer side of the green sub-pixel 130 is smaller than the side of the blue sub-pixel 120, and the shorter side of the green sub-pixel 130 is smaller than the side of the red sub-pixel 110.
[0027] Furthermore, the two green sub-pixels 130 are arranged in a mirror-symmetric configuration along the diagonal of pixel unit 100. This mirror-symmetric design ensures uniform light distribution and avoids color deviation.
[0028] Furthermore, the distances between the two green sub-pixels 130 and the blue sub-pixel 120 are equal, that is... Figure 2 In this context, e1 = e2. Equal spacing ensures even light distribution and improves display quality.
[0029] Furthermore, the distances between the two green sub-pixels 130 and the red sub-pixel 110 are equal, that is... Figure 2 In this context, d1 = d2. Equal spacing ensures even light distribution and improves display quality.
[0030] Furthermore, the blue sub-pixel 120 is located on both sides of the outer perimeter of pixel unit 100, and the distance to the outer perimeter of pixel unit 100 is equal, that is, in Figure 2 In the diagram, c1 = c2; the shorter sides of the two green sub-pixels 130 are equidistant from the outer edge of pixel unit 100, that is, in... Figure 2 In the middle, c3 = c4; the red sub-pixel 110 is close to both sides of the outer edge of pixel unit 100, and the distance to the outer edge of pixel unit 100 is equal, that is, in Figure 2 In the middle, c5 = c6; the long sides of the two green sub-pixels 130 are equidistant from the outer edge of pixel unit 100, that is, in Figure 2 In the equation, c7 = c8.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
