1. A display device comprising;
- a display panel having a high pixel and a low pixel, wherein the high pixel and the low pixel are formed in a pixel area; and
a driving section receiving a first image signal from an external device, outputting a second image signal to the high pixel by using gamma data that corresponds to a high pixel gamma curve, and outputting a third image signal to the low pixel by using gamma data that corresponds to a low pixel gamma curve,wherein the driving section outputs the third image signal to the low pixel by using the same gamma data for each of RGB data that corresponds to a low gradation of the low pixel gamma curve.

Abstract
A display panel has a high pixel and a low pixel that are formed in a pixel area. A driving section receives a first image signal from an external device, outputs a second image signal to the high pixel using gamma data that corresponds to a high pixel gamma curve, and outputs a third image signal to the low pixel using gamma data that corresponds to a Sow pixel gamma curve. A driving section outputs the third image signal to the low pixel using the same gamma data for RGB data that correspond to a low gradation of the low pixel gamma curve.

12. A display device comprising:
-
a display panel having a high pixel and a low pixel that are formed in a pixel area; a storing section storing high RGB gamma data corresponding to the high pixel and low RGB gamma data corresponding to the low pixel; a timing controller receiving a first image signal from an external device, outputting a second image signal adapted the first image signal to the high RGB gamma data, and outputting a third image signal adapted the first image signal to the low RGB gamma data; a gate driver outputting a gate signal to activate the gate line in response to controlling of the timing controller; and a data driver outputting the second and third image signals to the data line in response to the controlling of the timing controller, wherein the storing section stores same RGB gamma data, which corresponds to a low-gradation of the low RGB gamma data. - View Dependent Claims (13)
