Description
Technical Field

[0002] Liquid crystal display (LCD) is based on the directional arrangement of liquid crystal molecules under the action of electric field, so as to modulate light and display images. In order to meet the needs of large-scale display, multiple display screens are usually spliced to physically align the displays and maintain the consistency of color and brightness to achieve the unity of the overall visual effect, thus forming a display surface of larger size or specific shape.
[0003] At present, in the process of splicing multiple display screens, the border alignment of the display panel of the display screen will cause an invalid display area at the edge of the display screen, so that after directly splicing the multiple display screens, a splicing seam is formed at the edge of each display screen.

In order to enable any technician in the field to implement and use the present application, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can also be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the present application obscure. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.
[0056] First, as Figure 1 and Figure 2As shown, in one embodiment, the present application provides a display control method, which is applied to a spliced display device, wherein the spliced display device is formed by splicing at least two display screens 10, and there is a splicing gap between two adjacent display screens 10, and a filling display unit 20 is arranged at the splicing gap, and the filling display unit 20 includes a covering portion 21 that partially overlaps with the display screen 10 and a filling portion 22 corresponding to the splicing gap.
[0057] The display control method includes steps S101 to S103, which are described in detail below.
[0058] Step S101: obtaining a source image to be displayed by a splicing display device.
[0059] Step S102 : based on the display resolution of the display screen 10 , the size parameters of the covering portion 21 and the size parameters of the filling portion 22 , the screen source images corresponding to each display screen 10 and the filling source images corresponding to the filling display unit 20 are intercepted from the source images.
[0060] Step S103: displaying the screen source image and the filling source image through the display screens 10 and the filling display unit 20 respectively.
[0061] As an example, at a side angle, the edge of the filling display unit 20 will be transparent. Due to the refraction effect of light, the content displayed on the display screen 10 below the filling display unit 20 can be seen. If the area of the display screen 10 below the filling display unit 20 is not displayed, black edges (dark bands) are likely to appear at the edge of the filling display unit 20. If the area of the display screen 10 below the filling display unit 20 is white light, lines with higher brightness are likely to appear at the edge of the filling display unit 20. Therefore, in this embodiment, the screen source image is displayed through the display screen 10, so that it can be kept consistent with the brightness and color of the filling source image displayed by the filling display unit 20, so that the light refracted at the edge of the filling display unit 20 is coordinated with the current display screen.
[0062] In the above embodiment, since the filling display unit 20 has a covering portion 21 partially overlapping the display screen 10, the screen source image and the filling source image corresponding to each display screen 10 and the filling display unit 20 are intercepted from the source image to be displayed, so that the covered area of the display screen 10 and the covering portion 21 of the filling display unit 20 can display the same content, and at a side viewing angle, the dark band generated by the refraction of the filling display unit 20 is compensated by the screen source image displayed by the display screen 10 below it. In this way, the dark band phenomenon that may occur in the traditional splicing display device at a side viewing angle is improved, and the display screen of the splicing display device can be kept complete and coherent when viewed from all angles.
[0063] In some embodiments, the display area of the display screen 10 includes an uncovered display area that is not covered by the filling display unit 20 and an overlapped display area that is covered by the filling display unit 20. The screen source image displayed in the overlapped display area is consistent with the filling source image displayed by the covering portion 21. The screen source image displayed in the uncovered display area is different from the filling source image displayed by the filling portion 22.
[0064] In the above embodiment, the screen source image displayed by the overlapping display area is consistent with the filling source image displayed by the covering portion 21, so as to compensate the brightness and color of the light refracted at the edge of the filling display unit 20. In this way, the screen source image displayed by the uncovered display area is different from the filling source image displayed by the filling portion 22, so that each display screen and the filling display unit 20 can fully display the source image.
[0065] Reference Figure 2 and Figure 3 As shown, in the first embodiment, the spliced display device may include a first adjacent display screen 10a and a second adjacent display screen 10b, and the filling display unit 20 includes a filling portion 22 corresponding to the splicing gap between the first display screen 10a and the second display screen 10b, a first covering portion 21a partially overlapping the first display screen 10a, and a second covering portion 21b partially overlapping the second display screen 10b. The first display screen 10a includes a first uncovered display area 11a and a first overlapping display area 12a, and the second display screen 10b includes a second uncovered display area 11b and a second overlapping display area 12b.
[0066] As an example, step S102 may include: according to the width of the display resolution, the width of the cover portion 21, and the width of the filling display unit 20, respectively intercepting the first sub-source image M1, the second sub-source image M2, and the third sub-source image M3 corresponding to the display area of the first display screen 10a, the filling display unit 20, and the display area of the second display screen 10b from the source image. The screen source image includes the first sub-source image M1 and the third sub-source image M3; the filling source image includes the second sub-source image M2.
[0067] In the above embodiment, the first sub-source image M1, the second sub-source image M2 and the third sub-source image M3 are respectively cut out from the source image according to the width of the display resolution, the width of the covering portion 21 and the width of the filling display unit 20, so that the first sub-source image M1 displayed in the first overlapping display area 12a is consistent with the second sub-source image M2 displayed in the first covering portion 21a of the filling display unit 20, and the third sub-source image M3 displayed in the second overlapping display area 12b is consistent with the second sub-source image M2 displayed in the second covering portion 21b of the filling display unit 20. In addition, the first sub-source image M1, the second sub-source image M2 and the third sub-source image M3 displayed in the first uncovered display area 11a, the filling display unit 20 and the second uncovered display area 11b can form a complete source image.
