Display screen display optimization method

Abstract

The invention relates to a display screen display optimization method. The method comprises the following steps that: (a) current ambient light color temperature and current environment light brightness of a display screen are acquired in real time; (b) the color temperature adjustment target value of the display screen is calculated through utilizing a binary linear equation based on the current ambient light color temperature; (c) the brightness adjustment target value of the display screen is calculated through utilizing a piecewise function based on the current environment light brightness; and (d) the color temperature and the brightness of the display screen are adjusted according to the color temperature adjustment target value and the brightness adjustment target value. With the method adopted, parameters such as color temperature and / or contrast of the display screen can be controlled when the brightness of the display screen is adjusted, and therefore, the display of the display screen can better accord with the change of surrounding environment of the display screen, and image display quality can be improved.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to a display optimization method for a display screen. Background technique [0002] The display screen composed of LED dot matrix has some outstanding advantages such as high luminous efficiency, long service life, and large viewing angle range, and is suitable for outdoor display applications. However, the change of the ambient light where the outdoor LED display is located has different degrees of influence on the display effect of the display screen. This problem limits the in-depth promotion and application of the outdoor LED display to a certain extent. [0003] As we all know, from day to night, the ambient brightness varies greatly at different times. At night when the light is weak, if the brightness of the LED display is too high, the eyes will obviously feel uncomfortable and cause light pollution; while at noon when the light is strong, if the brightness of the ...

Problems solved by technology

[0008] Although the above solutions can effectively improve the display quality of the LED display, these methods,

[0009] 1) The adjustment of the display brightness is based on engineering experience data, which will vary due to the subjective judgment of the tester, and there is no uniform standard;

[0010] 2) Only adjusting the brightness of the LED display will not only cause power consumption problems and reduce the service life of the LED display, but also in the scene of direct sunlight, the display effect of the LED display cannot be significantly improved;

[0011] 3) The influence of the change of light color temperature on the display effect of the LED display is not considered
