Embodiment Construction

[0042] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] A display screen adjustment and display optimization method proposed in the following embodiments of the present invention is aimed at changes in external ambient light, based on pre-established historical experience data and display screen parameter adjustment models such as brightness and color temperature, for display screens such as brightness and color temperature. Parameters are automatically adjusted for display optimization. Specifically, the following will describe in detail the display optimization method for adjusting and displaying the display screen by time in this embodiment through the process of how to pre-establish historical experience data and display screen parameter adjustment models such as brightness and co...

Abstract

The invention relates to a display screen time period-based adjustment display optimization method. The method comprises the following steps that: (a) preset ambient light color temperature and environment light brightness which are corresponding to a time period in which a current time point is located are searched according to the current time point; (b) the color temperature adjustment target value of a display screen is calculated through utilizing a binary linear equation based on the ambient light color temperature; (c) the brightness adjustment target value of the display screen is calculated through utilizing a piecewise function based on the 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 based on time periods, 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 adjusting and displaying a display screen in time intervals. 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...
