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 l

Embodiment Construction

[0102] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0103] Due to the real-time nature of the existing ALS solution, when the ambient light occasionally changes briefly and within a small range (such as people passing by and blocking the angle of the light sensor from the light source, etc.), the brightness of the screen will also change accordingly. As a result, the brightness of the screen fluctuates in a small range, which affects the user experience, that is, the brightness of the screen will change with a slight change in the ambient light. Therefore, due to its real-time nature, the existing ALS solution will bring potential risks of screen brightness jitter, and because the system detects the illuminance value of...

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 ...
