Problems solved by technology

[0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a method and device for improving the display effect of the LED display screen, and realizes the allocation of low-gray-scale red, green and blue sub-pixels of the LED display screen while improving the grayscale accuracy of the LED display screen. While adjusting the ratio, it can also eliminate the problems of excessively poor color bars, jitter, and gray jumps on the LED display

Abstract

The invention provides a method and a device for improving the display effect of an LED display screen, and the method comprises the steps: expanding the original gray scale number of a display imageby N times, obtaining the original gray scale of each pixel point of the display image under the original gray scale number, converting the original gray scale into an expanded gray scale under the expanded gray scale number, and splitting the extended gray scale into a form of a first gray scale and a second gray scale; re-assigning a second gray scale in the extended gray scale of each pixel point of the display image according to a preset gray scale assignment strategy to obtain a to-be-corrected image; and performing brightness and color temperature correction on to-be-corrected image to obtain corrected display image, and displaying corrected display image in LED display screen. According to the invention, the gray scale precision of the display image can be improved, the jitter is eliminated, the adjustment of the low gray scale RGB ratio is realized, the color bar transition of the display image is uniform, and the display effect of the display screen is effectively improved.

Description

technical field [0001] The invention relates to the field of LED display correction, in particular to a method and a device for improving the display effect of an LED display screen. Background technique [0002] LED display has the characteristics of low energy consumption, high brightness, long life, and good performance stability. It is widely used in indoor places such as command centers, video conference rooms, studios, shopping malls, and outdoor large-screen displays. With the development of technology, Its requirements for display effects, such as contrast, brightness, and resolution, are also getting higher and higher. Due to the influence of the characteristics of the light-emitting chip, the current LED display screen has too high graying brightness, usually 0.2cd / m2, which cannot meet customer needs. In addition, due to the low grayscale accuracy of the current LED display, the ratio of red, green and blue sub-pixels in the low grayscale of the LED display is al...
