Embodiment Construction

[0041] The present invention provides a brightness control method and system for a display device. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] see figure 1 , figure 1 It is a flow chart of a preferred embodiment of the brightness control method of a display device provided by the present invention. As shown in the figure, the method includes the following steps:

[0043] Step S100, adding a plurality of LED lamps arranged in a matrix for backlighting on the display device in advance, each LED lamp provides backlighting for the corresponding display area on the display device, and captures each LED lamp in the video when recording th...

Abstract

The invention discloses a method and system for controlling brightness of a display device. A plurality of LED lamps arranged in a matrix for backlighting are added to the display device in advance, and each frame of the image in the video is collected when the video is recorded. The actual scene brightness value corresponding to the pixel point; according to the preset first brightness threshold value, the actual scene brightness value corresponding to each pixel point of each frame image in the video is subjected to limit value processing, and calculated according to the preset second brightness threshold value Corresponding extra brightness value; calculate the average value of the extra brightness values ​​of all pixels in the display area corresponding to each LED light in each frame image, and calculate the average value and the first brightness threshold and the second brightness threshold The ratio of the difference; adjust the brightness of the LED lights corresponding to the display area according to the ratio; make the viewer have a more realistic visual experience, make the display equipment such as TV movies have high-brightness display function, and achieve a realistic display effect .

Description

technical field [0001] The present invention relates to the technical field of brightness control of a display device, in particular to a brightness control method and system of a display device. Background technique [0002] With the continuous development and popularization of display products, more and more displays appear in our daily life, such as flat-panel displays such as mobile phones, tablet computers, etc., as well as TVs and theater systems. At present, the display system only has the traditional 3-primary-color grayscale display, and the brightness performance is relatively general, and the brightness is often displayed within a small range. ~255, however, the brightness range of the actual scene brightness value corresponding to this video is very large, which makes the video picture effect not realistic, and the visual experience is not realistic. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004]...
