Display Device and Method of Driving the Same
First Claim
1. A display device comprising:
- a display panel which comprises a plurality of dither blocks displaying an image that corresponds to a dither image signal; and
an image signal controller which generates the dither image signal by using a dither pattern that determines a plurality of dither pixels, which are to be dithered, from among a plurality of pixels included in each of the dither blocks,wherein each of the dither blocks comprises a plurality of pixels, whose respective polarities are inverted at least every one frame and which are driven accordingly, and comprises equal numbers of positive-polarity dither pixels and negative-polarity dither pixels.

Abstract
Provided are a display device with improved display quality and a method of driving the same. The display device includes: a display panel which includes a plurality of dither blocks displaying an image that corresponds to a dither image signal; and an image signal controller which generates the dither image signal by using a dither pattern that determines a plurality of dither pixels, which are to be dithered, from among a plurality of pixels included in each of the dither blocks, wherein each of the dither blocks includes a plurality of pixels, whose respective polarities are inverted every frame and which are driven accordingly, and comprises equal numbers of positive-polarity dither pixels and negative-polarity dither pixels.

11. A method of driving a display device, the method comprising:
-
assigning a dither pattern which determines a plurality of dither pixels, which are to be dithered, from among a plurality of pixels included in a dither block; generating a dither image signal by applying the dither pattern to an original image signal; and displaying an image corresponding to the dither image signal, wherein the dither pattern is assigned such that each dither block comprises equal numbers of positive-polarity dither pixels and negative-polarity dither pixels. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
