Description

Technical Field

[0001] The present invention belongs to the field of display technology, and in particular relates to a method and device for implementing display parameter adjustment of a display screen based on scenes and contents. Background Art

[0002] In the field of individual informationized combat, the display screen is a very important component of mobile smart terminals. In order to improve the display effect and visual experience of the screen, the display screen can be displayed at different brightness under different ambient light conditions, reducing the visual stimulation caused by the display screen being too bright in low light conditions, and avoiding the situation where the display screen is too dim in strong light and the screen content cannot be seen clearly. However, in the relevant technical solutions currently on the market, the screen brightness adjustment of the display screen triggered by the ambient light sensor relies on a default brightness curve, which makes the brightness adjustment too single-board and not flexible enough. There is no brightness adjustment method based on the scene and display content, which does not meet actual needs.

[0003] The existing technical solution only triggers the adjustment of the display screen brightness parameters based on the change of the ambient light sensor. The existing technical solution does not make a comprehensive judgment based on multiple influencing factors such as the current triggering scene and multiple elements of the current display content such as contrast and grayscale, and cannot achieve the best display effect. Summary of the invention

[0011] Find the corresponding display parameters of the display screen on the display parameter curve model according to the current display scene;

[0012] The display screen is adjusted according to the display parameters.

[0013] Furthermore, the method for acquiring the display parameters is to detect the contrast and grayscale displayed on the display screen, and obtain corresponding display parameters of the display screen according to the contrast and grayscale.

[0016] Furthermore, the ambient light attribute value of the current environment in which the terminal is located is detected in real time by a sensor.

[0017] Furthermore, the specific method of determining the display parameter curve model corresponding to the current display scene is:

[0018] Every time the user adjusts the brightness of the terminal, the package name of the current foreground application, the current brightness value, the final brightness value manually adjusted by the user, and the current ambient light value are recorded, and the brightness curves for various display scenarios are fitted based on these data.
