Embodiment Construction

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

[0022] Such as figure 1 As shown, it is a schematic flow chart of an embodiment of the method for adjusting the brightness uniformity of the display screen of the present invention, including steps:

[0023] Step S101: Divide the display screen to be adjusted and the switchable glass arranged in front of it into multiple display areas and switchable glass areas;

[0024] According to the solution of the present invention, a layer of light-adjustable glass is tightly pasted on the surface of the display screen, so that the light transmittance can be adjusted. The area of ​​the dimming glass can be divided into smaller areas, and the transparency can be improved. Dimmable glass can realize switching between transparent and opaque states of glass and adjustment of light transmittance through various m...

Abstract

Provided are a method and system for adjusting display screen luminance uniformity. The method comprises the steps that a display screen to be adjusted is divided into a plurality of display areas, and light adjusting glass arranged in front of the display screen is divided into a plurality of light adjusting glass areas; the luminance average value of each display area is obtained, the smallest luminance average value in the luminance average values is determined, and the smallest luminance average value is set as a target value; the compensating parameter of each display area to be adjusted is calculated according to the luminance average values and the target value, wherein the display areas to be adjusted are the display areas except for the display area corresponding to the smallest luminance average value; the light pervious parameters of the corresponding light adjusting glass areas are obtained according to the compensating parameters of the display areas to be adjusted, and the light transmittance of the light adjusting glass is adjusted according to the light pervious parameters. Through the scheme, the display screen luminance uniformity is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and system for adjusting brightness uniformity of a display screen. Background technique [0002] At present, due to the uneven brightness of the screen of the display screen, the phenomenon of dark edges and vignetting often occurs when the screen is displayed. Such as LCD display. As the size of the LCD panel increases, adverse visual effects such as dark edges and dark corners become more and more obvious. At present, most of the brightness uniformity of 46-inch LCD displays is below 85% when they leave the factory. Human eyes can easily see bad visual effects such as dark edges and dark corners of the LCD. 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] There are two existing solutions for improving the ...
