Method for controlling luminance of terminal screen and terminal

Abstract

The embodiment of the invention discloses a method for controlling the luminance of a terminal screen and a terminal. The method includes the steps that after the terminal determines that the luminance value of the screen of the terminal is a first screen luminance value, the information of eyeballs of eyes in a preset range is detected, and the size of pupils of the eyes is determined according to the detected information of the eyeballs of the eyes; then after the terminal determines that the size of the pupils of the eyes is larger than or equal to a pupil size threshold value, the luminance value of the terminal screen is set to be a second screen luminance value. According to the method and the terminal, the terminal obtains the size of the pupils of the eyes by detecting the information of the eyeballs of the eyes, then whether the terminal screen is watched with the eyes or not is determined, and under the condition that the screen is not watched with the eyes, the luminance of the terminal screen is reduced with the method of setting the luminance value of the terminal screen into the second screen luminance value, so that the power consumption of the terminal screen is effectively reduced, and the running time of the terminal is prolonged.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for controlling the brightness of a terminal screen and a terminal. Background technique [0002] Along with the continuous development of mobile communication technology, various intelligent terminals such as smart phones and tablet computers continue to emerge. The existing smart terminals not only have increasingly powerful functions, but also have better and better display effects, stylish appearance and easy to carry, and have become one of the indispensable daily tools in people's lives. [0003] With the rapid development of mobile Internet applications and social media, the screen size of the display screen or touch screen of the smart terminal tends to be larger. Large screens can bring users a more convenient reading experience, but the battery capacity of smart terminals is limited. The larger the screen size, the greater the power consumption,...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a terminal screen brightness control method and a terminal, which are used to solve the problem of poor user experience caused by automatically dimming the screen brightness or locking the screen when the user does not operate the smart terminal within a certain period of time after judging in the prior art. Realize the improvement of user experience on the basis of effectively reducing the power consumption of the terminal screen and prolonging the battery life of the terminal
