Abstract

An embodiment of the invention provides a method for adjusting the brightness of backlight, which relates to the technical field of terminals. The problem that the brightness of a mobile phone is inadequate is alleviated to a certain extent. The method comprises the steps of acquiring the maximum pixel brightness after a color coordinate calibration process, and adjusting the backlight supply current according to the maximum pixel brightness to adjust the brightness of backlight. The embodiment of the invention is applicable to the process of image display on a terminal.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of terminal technology, in particular to a method and device for adjusting the brightness of a backlight. [0003] 【Background technique】 [0004] For the display screen of the mobile phone, due to the possible difference in the color block of the backlight or the possible difference in the color filter of the touch screen, the color tone displayed by the mobile phone may appear yellowish or blue. In order to avoid this situation, color coordinate calibration (also known as white point balance debugging) is used in the prior art. This color coordinate calibration can adjust the ratio of each mobile phone screen by controlling the ratio of the three sub-pixels of red, green and blue. into a consistent color. In the process of color coordinate calibration, it is necessary to control the ratio of the three sub-pixels of RGB to make each gray scale of white reach our set white; but due to the physical lim...
