Method and device for regulating screen brightness and electronic device

Abstract

The invention provides a method for regulating screen brightness. The method includes the steps that a light collecting unit collects ambient light intensity and outputs voltage signals at intervals according to the light intensity; a core processing unit receives consistent voltage signals continuously, obtains a voltage value corresponding to current screen brightness according to a corresponding relation of the screen brightness stored by a storage unit with voltage values and the current screen brightness, compares the voltage signals with the voltage value, and controls a screen managing unit to increase or reduce the screen brightness if the signals are larger or smaller than the voltage value; and the first step is repeated from. According to the method for regulating the screen brightness, the screen brightness can be regulated according to the light intensity of the environment, suitable brightness can be guaranteed when a user is watching the screen, good definition of the screen is provided, watching requirements are satisfied, large amount of electric energy can be saved simultaneously, and the method is applicable to electronic devices, particularly mobile electronic devices.

Description

technical field [0001] The invention belongs to the field of display of electronic equipment, and in particular relates to a method and a device for automatically adjusting screen brightness. Background technique [0002] The display screen is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. With the extensive development of electronic equipment, more and more displays are used, and liquid crystal displays occupy a large share of them due to their thinness. [0003] The liquid crystal display is often affected by the environment, especially when it is in the sun, it is difficult to see the displayed content on the screen. In order to overcome these problems, some electronic devices will be equipped with the function of adjusting the screen brightness, but this function can only be manually pre-set. Adjusting or adjusting according to the visual experience when the environment ...

AI Technical Summary

Problems solved by technology

The advantage of this method is that it solves the problem of insufficient brightness of the screen under sunlight, but the brightness of the screen in this method is not very adjustable.
