Patent ID: 8810606

Claim:
A display device comprising: a pixel including a first subpixel and a second subpixel; a first signal line connected to the first subpixel and transmitting a first signal; a second signal line connected to the second subpixel and transmitting a second signal; a third signal line intersecting the first and the second signal lines, connected to at least one of the first and the second subpixels, and transmitting a third signal; a fourth signal line intersecting the first and the second signal lines and transmitting a fourth signal; a gray signal generating circuit which generates a first gray signal group and a second gray signal group that are different from each other; a selection circuit which alternately selects one from the first gray signal group and the second gray signal group and outputs the selected gray signal group to a data driver; and the data driver which generates a first data voltage corresponding to an image data for the pixel based on the first gray signal group when the first gray signal is selected at the selection circuit, or generates a second data voltage corresponding to the image data for the pixel based on the second gray signal group when the second gray signal is selected at the selection circuit, and then applies the first data voltage and the second data voltage alternately to the third signal line, wherein the first subpixel is supplied with the first data voltage, and the second subpixel is supplied with the second data voltage, wherein the first data voltage has a same polarity as the second data voltage, wherein the first data voltage corresponds to the image data based on the first gray signal group, wherein the second data voltage corresponds to the image data based on the second gray signal group.
