Patent ID: 8872863

Claim:
A method for driving a liquid crystal display device comprising a backlight portion having a light source region divided into a first region, a second region, a third region, and a fourth region; and a pixel portion which is divided into a first pixel region, a second pixel region, a third pixel region, and a fourth pixel region corresponding to the first region, the second region, the third region, and the fourth region, respectively, wherein the liquid crystal display device is displayed by a field sequential method, and wherein one-frame period comprises a plurality of subframe periods including a first subframe period, a second subframe period, and a third subframe period consecutively in this order, comprising the steps of: in the first subframe period, performing light emission at the same time in the first region and in the third region; performing non-light emission at the same time in the second region and in the fourth region, wherein a color of light emission in the first region is different from a color of light emission in the third region; in the second subframe period, performing light emission at the same time in the second region and in the fourth region; performing non-light emission at the same time in the first region and in the third region, wherein a color of light emission in the second region and a color of light emission in the fourth region are different from each other; and in the third subframe period, performing light emission at the same time in the first region and in the third region; performing non-light emission at the same time in the second region and in the fourth region, wherein a color of light emission in the first region is different from a color of light emission in the third region, wherein light emission or non-light emission is performed in the first region and in the third region, which are separated from each other with the second region interposed therebetween; and light emission or non-light emission is performed in the second region and in the fourth region, which are separated from each other with the third region interposed therebetween, wherein a color of light emission in the first region in the first subframe period is the same as a color of light emission in the second region in the second subframe period, and wherein the color of light emission in the second region in the second subframe period is different from a color of light emission in the third region in the third subframe period.
