Description

Technical Field

[0002] Liquid crystal displays (LCDs) are based on the directional alignment of liquid crystal molecules under the influence of an electric field, which modulates light to display images. To meet the demand for large-scale displays, multiple displays are usually spliced ​​together to physically align them and maintain consistency in color and brightness, thereby achieving a unified overall visual effect and forming a larger or more specific shaped display surface.

[0003] Currently, in the process of splicing multiple displays, the wiring of the display panel frame will cause invalid display areas at the edges of the display, resulting in splicing seams at the edges of each display after directly splicing multiple displays. Usually, by setting up filler display units with the same width as the splicing seam, the images displayed on the spliced ​​display surface can be connected as one.

[0004] However, since the filler display unit covers the display screen, the splicing edge is easily visible from a side view, especially when the observer's line of sight forms an angle with the screen surface, resulting in dark bands on the screen from a side view. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

It should be understood that those skilled in the art will recognize that this application can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid unnecessary detail that would obscure the description of this application. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0056] Firstly, such as Figure 1 and Figure 2As shown, in one embodiment, this application provides a display control method applied to a splicing display device. The splicing display device is formed by splicing at least two displays 10. There is a splicing gap between two adjacent displays 10. A filling display unit 20 is provided at the splicing gap. The filling display unit 20 includes a covering part 21 that partially overlaps with the display 10 and a filling part 22 corresponding to the splicing gap.

[0057] The display control method includes steps S101-S103, which will be described in detail below.

[0058] Step S101: Obtain the source image displayed by the display device to be spliced.

[0059] Step S102: Based on the display resolution of the display screen 10, the size parameters of the covering part 21 and the size parameters of the filling part 22, extract the screen source image corresponding to each display screen 10 and the filling source image corresponding to the filling display unit 20 from the source image.

[0060] Step S103: Display the screen source image and the fill source image through each display screen 10 and the fill display unit 20 respectively.

[0061] As an example, from a side viewpoint, light may pass through the edges of the filling display unit 20. Due to the refraction of light, the content displayed on the display screen 10 below the filling display unit 20 becomes visible. If the area of ​​the display screen 10 below the filling display unit 20 is not displayed, a black border (dark band) may 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 illuminated by white light, brighter lines may appear at the edge of the filling display unit 20. Therefore, in this embodiment, the display screen 10 displays the source image of the screen, ensuring that its brightness and color are consistent with the 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 that partially overlaps with the display screen 10, by extracting the screen source image and the filling source image corresponding to each display screen 10 and the filling display unit 20 from the source image to be displayed, the area covered by the display screen 10 and the covering portion 21 of the filling display unit 20 can display the same content. From a side viewing angle, the dark bands generated by the refraction of the filling display unit 20 are compensated by the screen source image displayed on the display screen 10 below it. Thus, the dark band phenomenon that may occur in traditional splicing display devices from a side viewing angle is improved, and the display screen of the splicing display device remains complete and continuous when viewed from various angles.

[0063] In some embodiments, the display area of ​​the display screen 10 includes an uncovered display area not covered by the filling display unit 20 and an overlapping display area covered by the filling display unit 20. The screen source image displayed in the overlapping 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 in the overlapping display area is consistent with the filling source image displayed in the overlay section 21, so as to compensate for 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 in the uncovered display area is different from the filling source image displayed in the filling section 22, so that each display screen and the filling display unit 20 can display the source image completely.

[0065] Reference Figure 2 and Figure 3 As shown, in the first embodiment, the splicing display device may include adjacent first display screens 10a and second display screens 10b. 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: extracting a first sub-source image M1, a second sub-source image M2, and a third sub-source image M3 from the source image, corresponding to the display area of ​​the first display screen 10a, the display area of ​​the filling display unit 20, and the display area of ​​the second display screen 10b, respectively, based on the width of the display resolution, the width of the covering portion 21, and the width of the filling display unit 20. 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 embodiments, the first sub-source image M1, the second sub-source image M2, and the third sub-source image M3 are extracted from the source image according to the width of the display resolution, the width of the overlay portion 21, and the width of the filling display unit 20, respectively. This allows the first sub-source image M1 displayed in the first overlapping display area 12a to be consistent with the second sub-source image M2 displayed in the first overlay portion 21a of the filling display unit 20, and the third sub-source image M3 displayed in the second overlapping display area 12b to be consistent with the second sub-source image M2 displayed in the second overlay portion 21b of the filling display unit 20. Furthermore, 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.

[0068] Combination Figure 3 As an example, the resolution of the source image is A*L, and the resolution of the first display screen 10a and the second display screen 10b is H*L. Wherein, the width of the source image's resolution is A = 2H + W - 2X. L is the length of the source image, the first display screen 10a, and the second display screen 10b's resolution, and H is the width of the first display screen 10a and the second display screen 10b's resolution. W is the width of the filling display unit 20, and X is the width of the covering portion 21.

[0069] Reference Figure 3 and Figure 4 For example, the width of the first sub-source image M1 is H, the pixel coordinates of the source image corresponding to the starting display pixel are (0,0), and the pixel coordinates of the source image corresponding to the ending display pixel are (H,0); wherein, the pixel coordinates of the source image corresponding to the starting display pixel of the first sub-source image M1 displayed in the first uncovered display area 11a are (0,0); and the pixel coordinates of the source image corresponding to the starting display pixel of the first sub-source image M1 displayed in the first overlapping display area 12a are (HX,0).

[0070] As an example, the width of the second sub-source image M2 is W, and the pixel coordinates of the source image corresponding to the initial display pixel are (HX, 0); wherein, the pixel coordinates of the source image corresponding to the initial display pixel of the second sub-source image M2 displayed by the first covering part 21a are (HX, 0). The pixel coordinates of the source image corresponding to the initial display pixel of the second sub-source image M2 displayed by the filling part 22 are (H, 0); the pixel coordinates of the source image corresponding to the initial display pixel of the second sub-source image M2 displayed by the second covering part 21b are (H+W-2X, 0).

[0071] As an example, the width of the third sub-source image M3 is H, and the pixel coordinates of the source image corresponding to the starting display pixel are (H+W-2X,0). Specifically, the pixel coordinates of the source image corresponding to the starting display pixel of the third sub-source image M3 displayed in the second overlapping display area 12b are (H+W-2X,0); the pixel coordinates of the source image corresponding to the starting display pixel of the third sub-source image M3 displayed in the second uncovered display area 11b are (H+WX,0).

[0072] Where H is the width of the display resolution and X is the width of the covering portion 21. In the above embodiment, the starting display pixels of the first sub-source image M1 displayed in the first overlapping display area 12a and the second sub-source image M2 displayed in the first covering portion 21a both correspond to the pixel coordinates (HX, 0) of the source image, thus maintaining the consistency between the first sub-source image M1 displayed in the first overlapping display area 12a and the second sub-source image M2 displayed in the first covering portion 21a. Similarly, the third sub-source image M3 displayed in the second overlapping display area 12b and the second sub-source image M2 displayed in the second covering portion 21b are also consistent. The first sub-source image M1 displayed in the first uncovered display area 11a, the second sub-source image M2 displayed in the filling display unit 20, and the third sub-source image M3 displayed in the second uncovered display area 11b contain all the pixels of the source image, achieving complete display of the source image.

[0073] Reference Figure 5 In the second embodiment, the splicing display device may include a first display screen 10a, a second display screen 10b, and a third display screen 10c arranged sequentially.

[0074] A first filling display unit 20a is disposed between the first display screen 10a and the second display screen 10b, and a second filling display unit 20b is disposed between the second display screen 10b and the third display screen 10c. The first filling display unit 20a includes a first filling portion 22 corresponding to the seam 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 second filling display unit 20b includes a second filling portion 22 corresponding to the seam between the second display screen 10b and the third display screen 10c, a third covering portion 21c partially overlapping the second display screen 10b, and a fourth covering portion 21d partially overlapping the third display screen 10c. The first display screen 10a includes a first uncovered display area 11a and a first overlapping display area 12a, the second display screen 10b includes a second uncovered display area 11b, a second overlapping display area 12b and a third overlapping display area 12c, and the third display screen 10c includes a third uncovered display area 11c and a fourth overlapping display area 12d.

[0075] In step S102, based on the width of the display resolution, the width of the first covering part 21a and the second covering part 21b, and the width of the filling display unit 20, a first sub-source image M1, a second sub-source image M2, a third sub-source image M3, a fourth sub-source image M4, and a fifth sub-source image M5 corresponding to the display areas of the first display screen 10a, the first filling display unit 20a, the second display screen 10b, the second filling display unit 20b, and the third display screen 10c, respectively, can be extracted from the source image.

[0076] The screen source images include a first sub-source image M1, a third sub-source image M3, and a fifth sub-source image M5, while the filling source images include a second sub-source image M2 and a fourth sub-source image M4.

[0077] As an example, the resolution of the source image is A*L, and the resolutions of the first display screen 10a, the second display screen 10b, and the third display screen 10c are H*L. Wherein, the width of the source image's resolution is A = 3H + 2W - 4X.

[0078] Reference Figure 6 For example, the width of the first sub-source image M1 is H, and the pixel coordinates of the source image corresponding to the starting display pixel are (0,0); wherein, the pixel coordinates of the source image corresponding to the starting display pixel of the first sub-source image M1 displayed in the first uncovered display area 11a are (0,0); and the pixel coordinates of the source image corresponding to the starting display pixel of the first sub-source image M1 displayed in the first overlapping display area 12a are (HX,0).

[0079] As an example, the width of the second sub-source image M2 is W, and the pixel coordinates of the source image corresponding to the starting display pixel are (HX, 0); wherein, the pixel coordinates of the source image corresponding to the starting display pixel of the second sub-source image M2 displayed by the first covering part 21a are (HX, 0); the pixel coordinates of the source image corresponding to the starting display pixel of the second sub-source image M2 displayed by the first filling part 22 are (H, 0); and the pixel coordinates of the source image corresponding to the starting display pixel of the second sub-source image M2 displayed by the second covering part 21b are (H+W-2X, 0).

[0080] As an example, the width of the third sub-source image M3 is H, and the pixel coordinates of the source image corresponding to the starting display pixel are (H+W-2X,0). Specifically, the pixel coordinates of the source image corresponding to the starting display pixel of the third sub-source image M3 displayed in the second overlapping display area 12b are (H+W-2X,0); the pixel coordinates of the source image corresponding to the starting display pixel of the third sub-source image M3 displayed in the second uncovered display area 11b are (H+WX,0); and the pixel coordinates of the source image corresponding to the starting display pixel of the third sub-source image M3 displayed in the third uncovered display area 11c are (2H+W-3X,0).

[0081] As an example, the width of the fourth sub-source image M4 is W, and the pixel coordinates of the source image corresponding to the starting display pixel are (2H+W-3X,0). Specifically, the pixel coordinates of the source image corresponding to the starting display pixel of the fourth sub-source image M4 displayed by the third covering part 21c are (2H+W-3X,0); the pixel coordinates of the source image corresponding to the starting display pixel of the fourth sub-source image M4 displayed by the second filling part 22 are (2H+W-2X,0); and the pixel coordinates of the source image corresponding to the starting display pixel of the fourth sub-source image M4 displayed by the fourth covering part 21d are (2H+2W-4X,0).
