Background

As an important display device, the LED display screen has many advantages in display effect and use. The color of an LED display screen is produced by different combinations of the three basic colors of red (R), green (G) and blue (B), which are called RGB color modes. The color of the LED display screen is regulated by controlling the brightness of three basic colors of red, green and blue so as to achieve the required color effect. By adjusting the brightness of these three colors, almost all colors and color variations can be achieved, which is very important for displaying real images and video content. However, half of the color adjustment of the existing LED display screen is adjusted individually by an operator according to the situation of the operator through keys, time and labor are wasted, the color effect cannot adapt to the surrounding environment, and the color display effect of the LED display screen is directly affected.

In the prior art, application number CN202310545374.0 discloses a display screen brightness adjustment method, a device, computer equipment and a storage medium, wherein the display screen brightness adjustment method comprises the steps of obtaining task pictures, analyzing the task pictures, determining brightness information and color information corresponding to the task pictures, determining the number of tasks of the tasks, dividing display areas of a display screen according to the number of the tasks to form subarea display areas, optimally sorting the tasks based on the color information, displaying each task in the corresponding subarea display areas, and adjusting the brightness information of the subarea display areas corresponding to the task pictures based on the color information and the subarea display areas. Although to solve or improve the problem of poor experience of the display screen. However, the functions are relatively simple, and color adjustment is performed according to tasks, so that adjustment cannot be performed according to ambient light conditions, and the user experience is poor.

In the second prior art, application number CN202310077515.0 discloses a display screen correction method, a device and a nonvolatile storage medium in color gamut adjustment, wherein the method comprises the steps of determining target correction data before correction of RGB three primary colors of a target color gamut of a display screen in an ideal light emitting state, wherein the ideal light emitting state is a state that the change of the light emitting state of the RGB three primary colors of the display screen along with the correction data of the display screen accords with an ideal change rule, acquiring compensation parameters corresponding to the correction data interval according to the correction data interval corresponding to the target correction data before correction, compensating the target correction data before correction according to the compensation parameters to obtain corrected target correction data, and writing the corrected target correction data into the display screen, wherein the light emitting state of the RGB three primary colors of the display screen reaches the ideal light emitting state under the condition that the corrected target correction data is adopted. Although the technical problem that the color correction of the display screen caused by the fact that the correction data cannot ideally regulate the color of the lamp beads has larger error is solved. However, the display screen itself is improved only from its function, the ambient light condition is not set, and the display screen cannot bring excellent visual effect to the user as an adjustment factor.

In the prior art, the application number CN202310716659.6 discloses a color correction method and a color correction system of an LED display screen, which comprise an information acquisition unit, a data analysis unit, a simulation detection unit and a correction strategy generation unit, wherein the information acquisition unit is used for detecting environment influence information of a scene used by a target screen, the data analysis unit is used for determining the screen color temperature of the target screen according to the change degree of the color temperature of a light source, determining an environment influence period according to the illumination influence area of the scene used by the target screen, the simulation detection unit is connected with the data analysis unit and used for carrying out illumination detection and temperature detection on the target screen according to instruction information of the data analysis unit, and the correction strategy generation unit is used for determining the target screen working parameter adjustment quantity of the corresponding environment influence period according to the display effect parameters of the target screen so as to generate an illumination control strategy and generating a target screen temperature compensation strategy according to the brightness of the target screen under different detection temperatures, although the accuracy and the practicability of the color correction strategy are improved. But the color cannot be matched with ambient light, reducing the accuracy of the color correction strategy.

The first, second and third existing technologies lack monitoring means for the illumination conditions of the surrounding environment of the display screen, do not analyze the illumination conditions, and realize the technical means of matching the colors with the illumination conditions, so that the experience of users is reduced, the energy consumption is increased, and the service life of the display screen is shortened. Therefore, the invention provides the LED display screen color adjusting system and the LED display screen color adjusting method based on ambient light perception, and color parameters matched with the illumination conditions are obtained by sensing the illumination conditions, so that the automatic adjustment of the color parameters of the LED display screen is realized, and the user experience is greatly improved.
