Abstract

The invention discloses a display device and a color correction method. The display device comprises a display panel, a backlight module, a first sensing unit, a second sensing unit and a processing module. The first sensing unit is in charge of sensing instant ambient light messages of an environment that the display device is located. The second sensing unit is arranged at one side of the backlight module. The processing module is used for estimating target display brightness in accordance with the instant ambient light messages and for adjusting backlight intensity of the backlight module to adjusted backlight intensity, so that the display brightness of the display panel is generally identical to the target display brightness. The second sensing unit is used for sensing adjusted backlight messages of the backlight module. The processing module is used for estimating a color gain compensation value required by the display panel in accordance with the adjusted backlight messages andthe instant ambient light messages and for displaying images after compensating color of the display panel in accordance with the color gain compensation value.

Description

technical field [0001] The present invention is related to color correction, in particular to a display device and a color correction method applied to the display device. Background technique [0002] The current display device can automatically adjust the backlight intensity of the backlight module in conjunction with the ambient light brightness detection, so that the user's eyes will not be burdened by the brightness of the ambient light. In addition, the display device can cooperate with the chromaticity detection of the ambient light to make The color temperature of the light emitted in front of the display panel can have the same color performance as the ambient light, so that the human eyes can have a more comfortable feeling when watching the display device. [0003] However, in the process of adjusting the intensity of the backlight of the display device in accordance with the color performance of the ambient light, the backlight emitted by the backlight module is ...
