Abstract:
1. A display device comprising: a display panel including a plurality of pixels; a signal controller that stores a plurality of FRC patterns including data elements having first or second value, selects one of the FRC data patterns based on input image data having a first bit number, and converts the input image data into output image data having a second bit number smaller than the first bit number based on the selected FRC data pattern; and a data driver applying to the pixels data voltages corresponding to the output image data supplied from the signal controller, wherein the data voltages have first or second polarity, and the number of the pixels supplied with data voltages that correspond to the output image data converted based on the first value and have the first polarity is equal to the number of the pixels supplied with data voltages that correspond to the output image data converted based on the first value and have the second polarity in each data FRC pattern, and wherein each of the input image data includes two-bit lower bit data and upper bit data and the selection of the FRC patterns is based on the lower bit data of the input image data and a serial number of frames.
