Electronic equipment and display device screen brightness adjusting method thereof

Abstract

The invention discloses an electronic equipment and display device screen brightness adjusting method thereof, aiming at reducing jitter of the electronic equipment display device screen brightness. The method includes: a first and a second environment illuminance values are obtained, comparison is carried out to obtain an environment illuminance variation, whether the environment illuminance variation is over the preset threshold is judged to produce a judgement result; when the judgement result expresses that the environment illuminance variation is over the threshold, a target brightness value used for adjusting the electronic equipment display device screen brightness is determined according to the second environment illuminance value. The technical scheme of the invention reduces jitter of electronic equipment screen brightness and can prolong service life of screen, save system resource and power consumption and improve user experience.

Description

technical field [0001] The invention relates to electronic technology, in particular to an electronic device and a method for adjusting the screen brightness of a display device of the device. Background technique [0002] At present, ambient light sensor (Ambient Light Sensor, ALS) technology has been widely used in mobile devices (such as mobile phones, laptops) and other electronic devices to realize automatic adjustment of display according to the illuminance value of ambient light (unit: Lux). The screen brightness (unit: Nit) of a device such as a display or a display screen ensures the comfort of the user's eyes and provides the user with a good experience. [0003] In the notebook computer, the application idea of ​​ALS technology is: when the ALS function is activated, the notebook computer system periodically monitors the output information of the ALS sensor in real time, and the output information reflects the current ambient light value in real time; Brightness ...

AI Technical Summary

Problems solved by technology

For most of the application equipment, the light illuminance of its environment generally does not change frequently, but is relatively stable within a certain range for a long time, such as in a well-lit office environment or a sunny city square for leisure. environment, etc., although in these environments, a slight change in ambient light will not affect the user experience, but the system is still likely to adjust the screen brightness in each detection cycle, making the screen brightness jitter

[0007] (2) The current ALS solution adjusts the screen brightness when adjusting the screen brightness, all of which are based on the ambient light value to find the preset brightness curve or lookup table, so under the same ambient light value, the system can only get the same one. The target brightness value obviously cannot meet the different usage habits of different users. For example, in the same environment, it is likely that some users want the screen brightness to be higher, while other users want the screen brightness to be lower.

Therefore, the existing solutions for adjusting the screen brightness of the display device according to the preset brightness curve or look-up table cannot really meet the needs of users, so that users can enjoy high-quality service experience
