Problems solved by technology

[0003] The application scenarios of LED display are very diverse. When it is applied in a colored environment, due to the superimposition of ambient light and video images, the color of the display screen will be distorted. In this way, it will not be able to convey correct video information to the viewers. , may also cause visual discomfort or even injury to the viewer

Embodiment Construction

[0019] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the LED display screen self-adjustment method of the present invention.

[0020] Such as figure 1 As shown, the LED display screen self-adjustment method in this embodiment includes the following steps:

[0021] 101: Obtain the hue, hue, and saturation of pictures and videos.

[0022] When the LED display screen plays pictures and videos in the laboratory space, its internal broadcast control software will immediately collect the parameter information related to hue, hue, and saturation. This is the standard value, analyze the light source, and output the corresponding coordinates of the light source Information, red light source coordinates (xr, yr, zr), green light source coordinates (xg, yg, zg), blue light source coordinates (xb, yb, zb), and store and record the data generated by playing pictures and videos at this time , the above parameter information is stored from time to time.

Abstract

The invention provides a self-adjusting method for color saturation of an LED display screen. Ambient light is analyzed to determine a three-primary-color synthesis ratio of the ambient light; a to-be-displayed color is adjusted automatically based on primary color superposition; and according to the adjusted color, red, green, blue transmitting light of all pixel points in an LED dot matrix are controlled to play a video picture, so that the pixels of the image played by the display screen match the ambient light intensity. Therefore, a problem of too high brightness or too low brightness oreven color distortion of the display screen under mapping of the ambient light intensity is solved; the visual enjoyment of the watcher is improved; and the visual damages on the watcher are reduced.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a method for self-adjusting the color saturation of an LED display screen. Background technique [0002] In general, the color of a reflective object depends on the color of the light source, and the human brain is able to detect and correct for this color change. On a sunny day, on a cloudy day, or in a room with light bulbs or fluorescent lights, the human eye can adapt to changes in color under different light sources without affecting human perception of white objects. However, the "white" presented by digital images in different environments is different. In order to make the displayed color consistent with the color perceived by the human eye, the digital image device must imitate the human brain and adjust it according to different environments. It must be defined as white. In order to be as white as possible to the human eye. This adjustment is called "white...
