AI Technical Summary

Technical Problem

It is difficult for existing display devices to effectively adjust the screen brightness when the ambient light illumination changes, resulting in excessive power consumption in high external illumination, and the high brightness cannot be achieved in low illumination environments, resulting in inconvenience in use.

Method used

By introducing an illuminance sensor and a controller into the display device, the pixel luminance on the display panel is adjusted according to the illuminance changes of ambient light. The controller can reduce or increase pixel brightness in short time intervals to adapt to changes in ambient light and ensure that the screen brightness is always appropriate.

Benefits of technology

It realizes automatic adjustment of screen brightness according to ambient light illumination, improves the energy efficiency and user experience of the display device, and avoids waste of power and visual discomfort caused by inadequate brightness.

Abstract

A display device is provided. The display device includes a display panel, an illuminance sensor, and a controller. The display panel includes pixels configured to display an image. The illuminance sensor measures an illuminance of ambient light of the display panel. The controller controls the display panel such that the luminance of the pixel decreases during a first time interval when the illuminance of the ambient light decreases, and the controller controls the display panel such that the luminance of the pixel increases during a second time interval when the illuminance of the ambient light increases. The first time interval is shorter than the second time interval.
