The present disclosure relates to a display device, a display controller, and a display driving method that are capable of reducing a colorfulness perception difference between a normal area including a first driving area and an optical area including a second driving area by controlling at least one of the number of light emitting pixels per unit area, luminance, and saturation of an area between the first driving area and the second driving area, which have different numbers of light emitting pixels per unit area, when a high saturation image is displayed.

Display device, display controller, and display driving method

A display device and a driving method thereof are proposed, the display device including an image conversion apparatus receiving a first image signal from the outside and outputting a second image signal by converting a luminance of the received first image signal; a controller generating image data based on the second image signal; a source driver outputting data signals based on the image data; a display panel including a plurality of sub-pixels that emit light based on the data signals; and a memory, wherein the image conversion apparatus generates the second image signal by converting the luminance of the first image signal in such a manner a to satisfy a reference maximum luminance value stored in the memory.

Display device and driving method thereof according to capturing conditions of an image

A gamma compensation method and a display device using the same are disclosed. The gamma compensation method includes: sensing a level of external illuminance; determining whether the sensed level of external illuminance is equal to or lower than a predetermined illuminance, wherein when the sensed level is equal to or lower than the predetermined illuminance, the luminance of the display device is reduced to an optimum luminance; and modulating gray levels of input data of the display device based on a first gamma curve when the sensed level of external illuminance is equal to or lower than the predetermined illuminance, and modulating based on a second gamma curve when the sensed level of external illuminance is greater than the predetermined illuminance, wherein the first gamma curve includes a concave curve set in a low gray level area and a convex curve set in a high gray level area, and the concave curve and the convex curve are connected via an inflection point.
