Problems solved by technology

[0003] In the prior art, when the screen of the electronic terminal is off, the ambient light sensor of the electronic terminal will be turned off accordingly; when the screen of the electronic terminal is on, the electronic terminal will enable the ambient light sensor to detect and report the ambient light intensity value, As the screen brightness of the electronic terminal is getting faster and faster, at present, the electronic terminal can only receive the ambient light intensity value reported by the ambient light sensor after the screen is switched on. The ambient light intensity value is used to set the backlight brightness value, and in this case, the screen of the electronic terminal will flicker

Abstract

The invention discloses a screen backlight brightness value adjusting method and device applied to an electronic terminal. The screen backlight brightness value adjusting method comprises the steps of: acquiring and storing an ambient light intensity value of the electronic terminal in a screen turn-off state of the electronic terminal; sensing whether an object approaches the electronic terminal; if an object approaching the electronic terminal is sensed, acquiring the latest acquired ambient light intensity value of the electronic terminal; and setting the screen backlight brightness value of the electronic terminal according to the acquired ambient light intensity value. By adopting the technical solution, the screen backlight brightness value can be automatically set before the electronic terminal enters a screen turn-on state from the screen turn-off state..

Description

technical field [0001] The invention relates to the technical field of screen adjustment, in particular to a method and device for adjusting the brightness value of a screen backlight applied to an electronic terminal. Background technique [0002] At present, the electronic terminal can intelligently adjust the backlight brightness value of the electronic terminal screen through the ambient light sensor. When the ambient light intensity value reported by the ambient light sensor is large, the electronic terminal sets the backlight intensity value of its screen to a relatively high value, so as to reduce the power consumption of the electronic terminal and maximize the battery working time of the electronic terminal. [0003] In the prior art, when the screen of the electronic terminal is off, the ambient light sensor of the electronic terminal will be turned off accordingly; when the screen of the electronic terminal is on, the electronic terminal will enable the ambient li...
