Problems solved by technology

However, when the distance between the eyes and the display panel changes, the information perceived by the eyes on the display panel will change, especially when the ambient light is relatively bright and the distance becomes farther, the perception of the information by the eyes will be greatly reduced
At present, this problem can be compensated simply by adjusting the brightness of the backlight, but it causes a large increase in power consumption (for small and medium-sized liquid crystal display panels, the power consumption of the backlight accounts for more than 80%). How to ensure the visual effect of the display panel while reducing the Backlight power consumption is a topic worth studying

Abstract

The invention discloses a method used for reducing the power consumption of a display panel. The method includes the following steps: measuring a distance between the eyes of a user and a display panel through an infrared sensing unit, and measuring ambient brightness through an ambient light sensing unit; transmitting the measured distance to a processing control unit through the infrared sensingunit, and transmitting the measured ambient brightness to the processing control unit through the ambient light sensing unit; and adjusting the resolution of the display panel through the processingcontrol unit according to the measured distance and the measured ambient brightness.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a method for reducing power consumption of a display panel and a display panel device with low power consumption. Background technique [0002] At present, the part with the largest power consumption in the display modules of various portable devices such as mobile phones and tablets is the backlight LED part. Moreover, the trend of thinning and thinning in mobile phones and tablets makes the development of the size and capacity of batteries extremely limited. In order to solve the limitation of battery capacity and reduce power consumption, people have invented content adaptive brightness control (Content Adaptive Brightness Control, CABC) technology and light adaptive brightness control (Light Adaptive Brightness Control, LABC) technology. The so-called LABC technology is mainly to adjust the corresponding backlight brightness control technology of the portable device 2 by se...
