Intelligent regulation method for display screen backlight brightness and system for intelligent regulation method

Abstract

The invention provides an intelligent regulation method for display screen backlight brightness, which is characterized by comprising the following steps of: presetting a reference table in which display screen backlight values and environment light brightness valves correspond; acquiring the current environment light brightness valve, and setting the display screen backlight value according to the reference table; when a user feels that the display screen backlight brightness is not proper, performing manual setting; and after confirmation is ended, updating the new display screen backlight value into the reference table and enabling the new display screen backlight value to correspond to the current environment light brightness valve. The invention also provides a system for implementing the method, which is characterized by comprising a photosensitive module, a matching module, a light control module, a manual regulation module and an updating module. According to the intelligent regulation method for the display screen backlight brightness, not only can the automatic regulation function of the display screen backlight brightness be utilized but also the personal requirements of different users can be met, and thereby, the man-machine running-in degree is increased, and the comfort requirements of the users on visual sensation can be met.

Description

technical field [0001] The invention relates to an intelligent adjustment method and system for display backlight brightness Background technique [0002] At present, handheld mobile devices with photosensitive devices can automatically adjust the brightness of the display screen backlight according to the brightness of the current environment to meet the needs of users under different lighting conditions. The technical solution is generally to use a preset reference table corresponding to the brightness value of the display screen backlight and the ambient light brightness value, obtain the ambient light brightness information by the photosensitive device, and then extract the corresponding backlight brightness value according to the reference table to adjust the brightness of the display screen backlight. . Among them, the reference table is for the designers to study and study the user's usage habits (using a brighter display screen brightness under a brighter ambient li...

Problems solved by technology

However, the defect of the current technical solution is that when the user manually sets the brightness of the display backlight under a certain lighting condition, if the lighting condition changes, even if the lighting condition returns to the setting, the brightness of the display backlight will automatically change. If the user wants to adjust the brightness to suit himself, he needs to manually adjust it again

In this way, the manual adjustment function does not play much role in essence
