Display device and driving method thereof

A display device comprising:

• a display panel comprising pixels;
• and
• a display panel driver configured to drive the display panel,
• wherein the display panel driver comprises a timing controller configured to receive image signals and timing signals from the outside, to convert at least some of the image signals, and to output the converted image signals, each of the image signals corresponding to a respective one of the pixels,
• wherein the image signals comprise first image signals corresponding to a first area in the display panel,
• wherein each of image signals corresponds to each of the pixels and comprises a red signal, a green signal, and a blue signal,
• wherein the timing controller comprises a signal receiver configured to receive the image signals and the timing signals, and a first converter configured to receive the first image signals from the signal receiver, to perform color weakness-compensating conversion on the first image signals, and to output the converted first image signals,
• wherein the timing controller further comprises a selection signal generator configured to generate selection signals, and the selection signals corresponding to the first area defined by coordinate information received from outside have a first logic value,
• wherein the selection signal generator is further configured to receive the coordinate information comprising a first direction start coordinate, a first direction end coordinate, a second direction start coordinate, and a second direction end coordinate, and
• wherein each one of the first and second start coordinates and the first and second end coordinates corresponds to a respective one of the pixels.
