摘要： A display device includes a light sensor, a controller, a data driver, and a scan driver. The controller is configured to correct an input image signal based on an electrical signal output by the light sensor and an input image signal, the controller includes: a first color coordinate calculation unit configured to calculate a color coordinate of reflected light; a second color coordinate calculation unit configured to calculate a color coordinate of dark room output light for at least two grayscale value sections; a combination unit configured to combine the reflected light color coordinate and the dark room output light color coordinate together; and a gamma value setting unit configured to set a gamma value based on a deviation between the combination light color coordinate output by the combination unit and a reference color coordinate.
