Patent ID: 7995044

Claim:
A display device, comprising: a plurality of pixels arranged in a matrix; a plurality of data lines coupled with the pixels; a switching element coupled between a first data line and a second data line adjacent to the first data line; a signal controller configured to process input image signals and configured to output output image signals; a gray voltage generator configured to generate a plurality of gray voltages; and a data driver configured to select data voltages from the gray voltages corresponding to the output image signals received from the signal controller, and configured to apply the data voltages to the data lines, wherein when either all bits of the input image signal have a first value or all bits of the input image signal have a second value, the signal controller outputs the output image signal, all bits of the output image signal having the first value, and wherein the signal controller generates and outputs a switching control signal for controlling the switching element, and the signal controller does not output the switching control signal when all bits of the output image signal have the first value.
