DISPLAY DEVICE AND DISPLAY DEVICE DRIVING METHOD
First Claim
1. A display device comprising:
- a signal controller configured to receive an input image signal and to generate a changed image signal, wherein the signal controller divides the input image signal into red, green and blue image signals, changes the blue image signal to at least one of a first blue image signal and a second blue image signal, matches white balance of at least one of the red, green, first blue and second blue image signals, and generates the changed image signal by compensating a gamma value of the at least one of the red, green, first blue and second blue image signals;
a display panel configured to display an image corresponding to the changed image signal, wherein the display panel comprises a pixel comprising a red sub-pixel, a green sub-pixel, a first blue sub-pixel and a second blue sub-pixel; and
a data driver configured to receive the changed image signal from the signal controller and to apply a data voltage corresponding to the changed image signal to the display panel.

Abstract
A display device includes: a signal controller which receives an input image signal and generates a changed image signal, where the signal controller divides the inputted image signal into red, green and blue image signals, changes the blue image signal to a first blue image signal or a second blue image signal, matches white balance of the red, green, first blue or second blue image signals, and generates the changed image signal by compensating a gamma value of the red, green, first blue or second blue image signals; a display panel which displays an image corresponding to the changed image signal, where the display panel includes a pixel including red, green, first blue and second blue sub-pixels; and a data driver which receives the changed image signal from the signal controller and applies a data voltage corresponding to the changed image signal to the display panel.

12. A driving method of a display device, the method comprising:
-
dividing an inputted image signal into red, green and blue image signals; changing the blue image signal to at least one of a first blue image signal and a second blue image signal; generating a white balanced image signal by matching white balance of at least one of the red, green, first blue and second blue image signals; and generating a changed imaged signal by compensating a gamma value of the white balanced image signal to transmit the changed image signal to a data driver of the display device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
