Abstract
A display device includes a driving control circuit that receives an input image signal and outputs an output image signal, a data driving circuit that outputs a data signal corresponding to the output image signal, and a display panel including a plurality of pixels to display an image corresponding to the data signal. The driving control circuit determines an amount of time the input image signal is maintained as a still image, determines a color coordinate gain based on the amount of time and outputs the output image signal based on the color coordinate gain.

A display device, comprising:
- a driving control circuit which receives an input image signal and outputs an output image signal;
- a data driving circuit which outputs a data signal corresponding to the output image signal;
- and
- a display panel including a plurality of pixels and which displays an image corresponding to the data signal,
- wherein the driving control circuit determines an amount of time the input image signal is maintained as a still image, determines a color coordinate gain from the amount of time and outputs the output image signal based on the color coordinate gain.
A display device, comprising:
- a driving control circuit which receives an input image signal and outputs an output image signal;
- a data driving circuit which outputs a data signal corresponding to the output image signal;
- and
- a display panel including a plurality of pixels and which displays an image corresponding to the data signal,
- wherein the driving control circuit determines an amount of time the input image signal is maintained as a still image, determines a luminance gain and a color coordinate gain from the amount of time and outputs the output image signal based on the luminance gain and the color coordinate gain.
An operation method of a display device, the operation method comprising:
- determining whether an input image signal is a still image;
- counting, by a counter, an amount of time the input image signal is maintained as the still image to generate a count signal;
- calculating a color coordinate gain based on the count signal;
- and
- converting the input image signal into an output image signal based on the color coordinate gain.
