Embodiment Construction

[0021] Various embodiments of the method and system for adjusting the brightness uniformity of the screen of a spliced ​​display device according to the present invention will be described in detail below.

[0022] like figure 1 As shown, it is a schematic flowchart of an embodiment of the method for adjusting the brightness uniformity of the screen of the splicing display device of the present invention, including:

[0023] Step S101: Divide the screen into a middle area and a border area, and detect the average brightness value of each pixel in the middle area and the minimum brightness value of the pixels in the border area;

[0024] There are many ways to divide the screen into the middle area and the border area. For example, it can be divided according to the screen resolution, or can be divided according to the length and width of the screen, or evenly divided. The size of the middle region and the size of the border region can be set according to empirical ratios. Wh...

Abstract

The invention discloses a method and a system for adjusting brightness uniformity of a screen of a splicing display device. The method comprises the steps as follows: dividing the screen into a middle area and a boundary area, and detecting the average brightness value of each pixel in the middle area and the minimum brightness value of the pixels in the boundary area; calculating a compensating parameter of the middle area according to the average brightness value and the minimum brightness value, and calculating a compensating parameter of the boundary area according to the minimum brightness value; performing brightness compensation on each pixel in the middle area of the screen according to the compensation parameter of the middle area; performing brightness compensation on the boundary area of the screen according to the compensation parameter of the boundary area; and performing boundary weakening treatment on the compensated screen. According to the method and the system, the brightness uniformity is improved.

Description

technical field [0001] The present invention relates to the technical field of splicing display, in particular to a method and system for adjusting brightness uniformity of a screen of a splicing display device. Background technique [0002] The splicing display device is a large-screen display system including multiple small screens, and is generally used for super-large-screen display of one screen and multi-window display of multiple screens. At present, due to the uneven brightness of the screen, dark edges and dark corners often appear when the screen is displayed. When the phenomenon of dark edges and corners is obvious, it will affect the display effect of the screen. Therefore, it is more and more important to adjust the brightness uniformity of the screen. [0003] Some of the traditional techniques for adjusting brightness uniformity use multi-point gradient compensation techniques. This kind of compensation has the disadvantage of aperture effect after passing ...
