Example Embodiment

[0061] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0062] The core idea of ​​the present invention is: calculate the current environmental brightness according to the daylight saving time information and the current time point information, and then combine the multi-point average brightness and the calculated current environmental brightness to calculate the backlight control parameters to perform the display on the terminal Backlight control.

[0063] The process of calculating the current ambient brightness based on the daylight saving time information and the current time point information will be described below first. details as follows:

[0064] Divide the day into several time periods, and set the environmental brightness value E for each time period. The variable E is used to replace REGmax according to the change of the environmental brightness, and REGmax i...

Abstract

The invention discloses a backlight control method for a display terminal, and the method comprises the steps: obtaining the current time and daylight saving time information; obtaining current environment brightness matched with the current time and daylight saving time information according to the current time and daylight saving time information; obtaining the mean brightness information of a plurality of points of a to-be-displayed signal; and carrying out the backlight control of the display of the to-be-displayed signal according to the mean brightness information of the plurality of points and the current environment brightness. The invention also discloses a backlight control device for the display terminal, and a television. According to the invention, the method solves a problem that the detection of the environment brightness needs to be implemented through the increase of hardware cost in the prior art.

Description

technical field [0001] The invention relates to the field of backlight control, in particular to a backlight control method and device for a display terminal. Background technique [0002] In order to obtain a more comfortable viewing effect for the user on the TV, there is a solution in the prior art to dynamically adjust the display brightness of the screen. A brightness acquisition device is installed on the TV to collect the ambient brightness, and then the TV sets according to the signal source brightness and the ambient brightness, Dynamically adjust the brightness of the backlight, and through image quality compensation measures, not only the overall power consumption of the TV is lower, but also the viewing effect of the TV screen is more comfortable while maintaining the subjective brightness experience. [0003] However, the above-mentioned solutions often need to increase the support of hardware to realize the detection and calculation of the ambient brightness, s...
