[0035] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0036] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0037] With the rapid development of technology, especially in the display technology industry, Mini / Micro LED (mini / micro light emitting diode) technology is becoming the focus. With its excellent performance and increasingly smaller chip size, Mini / Micro LED technology is driving display technology into a new era.

[0038] In the field of packaging technology, MIP (MLED in Package), as a discrete device technology, has dominated the field of large-size displays. MIP technology encapsulates micro LED chips in independent packages. This technology provides greater flexibility and scalability, and helps to achieve more sophisticated display designs. For example, MIP technology supports seamless splicing of multiple LED screens to create a continuous, borderless display interface. In immersive display applications, such as building an immersive space with five or six LED screens, it can provide users with a 360-degree visual experience.

[0039] However, in the design of display screens in immersive spaces, one display surface may be connected to three, four, or more other display surfaces. The pixels of some display surfaces may be arranged in a specific direction, while the arrangement of the basic color lights of the pixels of display surfaces in other directions may be discontinuous. For example Figure 1 The display screen for an immersive room includes a bottom screen, a top screen, and four side screens (respectively a first side screen, a second side screen, a third side screen, and a fourth side screen, wherein the first side screen is located at Figure 1 The display surface at the front side of the viewing angle set in the second side screen is located at Figure 1 The display surface on the right side of the viewing angle set in the third side screen is located Figure 1 The display surface at the rear side of the viewing angle set in the fourth side screen is located at Figure 1 In order to improve the display effect, the pixel arrangement mode of as many display surfaces as possible in the display screen can be set to a continuous arrangement mode. For example, Figure 2 In the expanded schematic diagram of the display screen shown, the first side screen, the third side screen, the bottom screen and the top screen can be set as an arrangement in which the basic color lights of the pixels are set to extend in a fixed direction.

[0040] The basic color lights of the pixels may include LED lights of colors such as red, green, and blue (not limited to red, green, and blue). The arrangement of the basic color lights of the pixels is continuous, which can be understood as the arrangement of the basic color lights of the pixels on both sides of the splicing line of the two display surfaces is the same, such as extending in the same direction, or arranged in the same variation mode (such as red, green, and blue variation mode). Figure 2 As shown, in the flat unfolded display surface, the basic color lights of the pixels in the first side screen, the third side screen, the top screen and the bottom screen extend in the same direction, and at the splicing line of any two of the four display surfaces, the basic color lights of the pixels on both sides of the splicing line are arranged continuously.

[0041] After considering the consistency of the pixel extension direction of part of the display surface, when the second side screen, the fourth side screen, the first side screen, the third side screen, the bottom screen and the top screen are spliced, the arrangement of the basic color lights of the pixels will be discontinuous. This discontinuity is manifested in that the extension directions of the basic color lights of the pixels on both sides of the splicing line are different, or when the extension directions are the same, the basic color changes in a discontinuous manner. For example Figure 2 In the schematic diagram of the tiled display of the display shown in FIG. 1 , the discontinuous splicing method presented is as follows: Figure 3 The discontinuous splicing method of the basic colors shown includes different extension directions of the basic colors on both sides of the splicing line (such as Figure 3 As shown in the left figure in , the extension direction of the basic colors on the left side of the splicing line is perpendicular to the splicing line, and the extension direction of the basic colors on the right side of the splicing line is parallel to the splicing line), and the extension direction of the basic colors on both sides of the splicing line is the same, but the order of the basic colors is not continuous (such as Figure 3 As shown on the right, the basic colors on both sides extend in the same direction, but the colors are discontinuous). For example, Figure 2 The discontinuous splicing includes the splicing between edge 11 and edge 21, the splicing between edge 22 and edge 31, the splicing between edge 33 and edge 42, the splicing between edge 41 and edge 33, the splicing between edge 12 and edge 51, and the splicing between edge 32 and edge 52. Among them, the splicing between edge 11 and edge 21, the splicing between edge 22 and edge 31, the splicing between edge 33 and edge 42, and the splicing between edge 41 and edge 33 are pixels whose basic color lights extend in different directions (one is parallel to the splicing line and the other is perpendicular to the splicing line), and the splicing between edge 12 and edge 51, and the splicing between edge 32 and edge 52 have the same extension direction of the basic color lights, but the arrangement of the basic colors of the pixels is discontinuous (not continuously changing in the manner of red, green, and blue).

[0042] This asymmetry can easily lead to display problems such as color edges when displaying white images, especially at the junction of two display surfaces, which is not conducive to enhancing the immersive feeling of the immersive space.

[0043] In order to solve the above problems, the embodiment of the present application proposes a display screen. For the first display surface and the second display surface of the spliced ​​display, when the arrangement of the basic color lights of the pixels of the first display surface and the second display surface is discontinuous, compensation pixels are set at the connection between the first display surface and the second display surface. The compensation pixels can be used to compensate for the missing basic colors due to the uneven arrangement of the basic colors at the splicing line of the first display surface and the second display surface. Among them, the compensation pixels can be the basic color lights in the pixels at the splicing line converted into multi-color basic color lights, or can also be pixels added between the original pixels. The added pixels can be distributed along the splicing line, for example, can be distributed along the splicing line, and can be distributed alternately on both sides of the splicing line.

[0044] The basic colors are colors in the three primary colors, such as red, blue and green, etc. Or the basic colors can also be other types of basic colors used to mix and generate multiple colors.

[0045] When the single-color basic color lamps in the pixels at the splicing line are converted into multi-color basic color lamps, each basic element lamp in the first row closest to the splicing line in one of the display surfaces or both display surfaces at the splicing line can be replaced with multi-color basic color lamps. Figure 4 As shown, the replaced multi-color basic color lamp can display three basic color lamps at the position range of the original basic color lamp before replacement, and the three basic color lamps evenly divide the display range of the original basic color lamp.

[0046] It is not limited to replacing each basic element lamp in the first row closest to the splicing line in one or both display surfaces with a multi-color basic color lamp. It is also possible to replace some of the basic element lamps in the first row closest to the splicing line with multi-color basic color lamps. For example, it is possible to replace some of the basic element lamps in the first row closest to the splicing line with multi-color basic color lamps at certain intervals.

[0047] In a typical application scenario, such as Figure 5 As shown, when the first display surface and the second display surface are spliced, the color distribution of the basic color lights in the first row closest to the splicing line on the first display surface is a plurality of basic colors alternatingly distributed, and the color of the basic color lights in the first row closest to the splicing line on the second display surface is a single basic color, some of the basic color lights in the first row closest to the splicing line on the second display surface can be replaced with multi-color basic color lights, for example Figure 5 In an interval manner, some basic color lamps are selected from the basic color lamps in the first row closest to the splicing line on the second display surface in an interval manner to be determined as the basic color lamps that need to be replaced, and the display area of ​​each basic color lamp that needs to be replaced is replaced to display three basic color lamps.

[0048] In a possible application scenario, when the first display surface is spliced ​​with the second display surface, the color of the basic color lights in the first row closest to the splicing line on the first display surface is a single basic color, and the color of the basic color lights in the first row closest to the splicing line on the first display surface is a single basic color, and the two basic colors are discontinuous, then pixel compensation processing can be performed on the two rows of basic color lights closest to both sides of the splicing line, and some or all of the basic color lights in these two rows can be replaced with multi-color basic color lights.

[0049] Among them, the two rows of basic color lights on both sides of the splicing line closest to the splicing line are of a single color and are not continuous. Figure 6 As shown in the schematic diagram of the splicing line element, the colors of the two rows of basic color lights closest to the splicing line on both sides of the splicing line are the same, such as red, green or blue.

[0050] In this case, the two rows of basic color lights closest to the splicing line on both sides of the splicing line can be replaced with multi-color basic color lights, or part of them can be replaced with multi-color basic color lights. For example, the basic color lights closest to the splicing line on one side of the splicing line can be replaced with multi-color basic color lights. Or Figure 6 As shown, a portion of the basic color lamps on both sides of the splicing line closest to the splicing line are replaced with multi-color basic color lamps, and the replaced multi-color basic color lamps on the first side and the second side are alternately distributed, that is, the replaced multi-color basic color lamps on the first side are opposite to the unreplaced basic color lamps on the second side.

[0051] In a possible implementation, both rows of basic color lights are of a single color and are discontinuous, and may also be different colors. For example, in the first display surface, the basic color lights that gradually move away from the splicing line are distributed in red, green, and blue, and in the second display surface, the basic color lights that gradually move away from the splicing line are distributed in green, blue, and red. Since the display mode of the continuous basic color lights is red, green, blue, red, green, and blue, and the display mode of the basic color lights after splicing is red, green, blue, green, blue, and red, it means that the basic color lights of the pixels of the first display surface and the second display surface are discontinuous. In this case, pixels or basic color lights can be added at the splicing line in the direction of the splicing line, and the color of the added basic color lights can be the color missing from the continuous basic color lights. For example, in the previous example, the display mode of the basic color lights after splicing is red, green, blue, green, blue, and red, then a row of red basic color lights can be added at the splicing line, or a row of pixels can be added, each pixel including a plurality of basic color lights.

[0052] The added pixels or basic color lights may also be distributed alternately on both sides of the splicing line. The alternating distribution may be to add a row of basic color lights or pixels on both sides of the splicing line, and the basic color lights or pixels are arranged at a certain interval, and the interval position in the first display surface may correspond to the added position of the pixels or basic color lights in the second display surface.

[0053] The display screen in the embodiment of the present application can be effectively applied to Figure 1 The immersive house shown includes a scene with multiple display surfaces spliced ​​together. Figure 1 In the display scene of the six display surfaces spliced ​​together, the display screen includes a first side screen, a second side screen, a third side screen, a fourth side screen, a bottom screen and a top screen. In order to improve the display effect as much as possible, the basic color lights of the pixels of the first side screen, the third side screen, the top screen and the bottom screen are arranged continuously, and there will be no basic color unevenness at the splicing line between the first side screen, the third side screen, the top screen and the bottom screen. For the splicing line between the second side screen and the first side screen, the third side screen, the top screen and the bottom screen, and the splicing line between the fourth side screen and the first side screen, the third side screen, the top screen and the bottom screen, if the arrangement of the basic color lights is not continuous, compensation pixels can be set in the above manner to improve the continuity of the basic colors at the splicing line.

[0054] By setting basic color lights or pixels in the embodiment of the present application and performing pixel compensation on the discontinuous splicing lines, the continuity of the pixel colors at the splicing lines can be effectively improved, so that when white is displayed at the splicing lines, the probability of the occurrence of color edges or color lines can be effectively reduced, thereby improving the immersive display effect.

[0055] Figure 7A schematic diagram of a display control method of a display screen proposed in an embodiment of the present application, the method comprising:

[0056] In S701, display colors of the first display surface and the second display surface at the splicing line are detected.

[0057] When multiple display screens are spliced ​​together to display the content of the picture, the content of the picture displayed at the splicing line can be detected in real time, thereby effectively reducing the probability of color fringes or color lines appearing at the splicing line. When detecting the display color, the position of the splicing line in the picture can be determined according to the position of the splicing line, and the display color at the splicing line can be determined before playback according to the color distribution of the picture. In this way, pixel compensation control can be performed in advance at the splicing line.

[0058] In S702, when the display color at the stitching line is white, the compensation pixels in the white display area at the stitching line are controlled to display the compensation color.

[0059] The compensating color is the basic color missing due to uneven arrangement of the basic colors at the splicing line, including different arrangement directions of the basic colors, or the same arrangement directions of the basic colors but discontinuous arrangement order, that is, not arranged according to the standard color arrangement order.

[0060] The compensation pixels set in the white display area at the control stitching line are displayed as the missing colors when the basic colors are unevenly or discontinuously arranged. By lighting up the missing colors, the basic colors at the stitching line are made continuous, thereby effectively reducing the probability of color edges or color lines appearing at the stitching line and improving the immersive display experience of the display.

[0061] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
