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

Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] In one embodiment of the present invention, a method for improving the display effect of the LED display screen is provided, such as figure 1 As shown, the method includes the following steps:

[0035] Step S101: Obtain the display screen of the LED display screen.

[0036] Specifically, in the present invention, the display screen of the LED display is composed of multiple frames of red screens, multiple frames of green screens, and multiple frames of blue screens. scr...

Abstract

The present invention provides a method and device for improving the display effect of an LED display screen, which expands the original gray scale number of the display screen by N times, obtains the original gray scale of each pixel point of the display screen under the original gray scale number, and converts the original gray scale In order to expand the gray scale under the extended gray scale, the expanded gray scale is split into the first gray scale + the second gray scale; according to the preset gray scale assignment strategy, the expanded gray scale of each pixel in the display screen is re-assign the second gray scale to obtain the picture to be corrected; perform brightness and color temperature correction on the picture to be corrected to obtain the corrected display picture and display the corrected display picture on the LED display screen. The method and device provided by the present invention, It can improve the grayscale accuracy of the display screen, eliminate jitter, realize the adjustment of the low grayscale RGB ratio, make the color bars of the display screen excessively uniform, and effectively improve the display effect of the display screen.

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...
