Abstract

A method for regulating the brightness of a display device includes giving a cubic relational expression between environmental illuminance and the brightness of a display; giving correction methods for various parameters in the relational expression; and regulating the brightness of the display device according to the relational expression which is a cubic function. By the aid of the method, problems caused by nonlinear characteristics of human vision can be effectively solved, particularly, the problems caused by the nonlinear characteristics of the human vision under conditions that the environmental illuminance is high or the luminance is quite low in dawn and dusk are solved, and the brightness of displayed content of the display device is quite suitable for users.

Description

technical field

[0001] The invention relates to a method for adjusting the brightness of a display device, in particular to a method for automatically adjusting the brightness according to the ambient light intensity and being able to manually adjust the brightness. technical background

[0002] Currently, a display device has become an important device, which is widely used in various fields. However, the existing display devices still have some deficiencies. In order to allow users to use the display device comfortably under ambient light with different illuminance, the display device should be able to automatically adjust the brightness according to the ambient light; in order to meet the individual needs of each user for the brightness of the display device, the brightness of the display device should be able to User manual adjustment. In the Chinese invention patent with the publication number "CN101777334B" titled "Display Terminal Capable of Automatic Brightness Adj...
