Abstract

The invention is applicable to the technical field of display and provides a backlight adjustment method and a backlight adjustment device for a display device. The method comprises the following steps: respectively acquiring the difference multiple of light intensity value measured by an ambient light sensor built in a terminal relative to the light intensity value measured by an illuminometer according to each preset illuminance level; acquiring the actual measured light intensity value of the ambient light sensor; and adjusting the backlight brightness of the display device according to the actual measured light intensity value and the preset illuminance level at the light intensity value. A proper backlight adjustment scheme is provided for different types of terminal equipment, so that the difference between the ambient light intensity measured by the ambient light sensor and the real ambient light intensity is eliminated, the backlight brightness of the display device can be adjusted to a proper brightness value, the condition that the display screen is extremely bright or the brightness is insufficient is avoided, and the display effect is guaranteed.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a method and device for adjusting a backlight of a display device. Background technique [0002] At present, the backlight adjustment of the mobile phone is realized based on the ambient light sensor installed inside the mobile phone. The different ambient light intensity values ​​measured by the ambient light sensor will directly correspond to a light source brightness value, and the mobile phone screen is adjusted according to the light source brightness value. The brightness of the light source, so as to realize the adjustment of the brightness of the mobile phone screen with the change of the ambient light intensity. [0003] However, for different models of mobile phones, the ambient light intensity measured by the ambient light sensor is affected by various factors such as the orientation of the ambient light sensor on the main board of the mobile phone and the light trans...
