Patent ID: 8120602

Claim:
A flat panel display device comprising: a flat panel display panel; a controller to process an input image signal and generate a data signal to be supplied to the panel, the controller to generate a first signal having information on whether two or more consecutive data of the data signal comply with each other, and to output the first signal along with the data signal; and a data driver to generate a clock signal using the data signal and the first signal received from the controller and to supply the data signal to the panel using the generated clock signal, wherein a value of the first signal corresponding to Nth data of the data signal is determined based on whether N−1th data of the data signal complies with the Nth data of the data signal; wherein the value of the first signal corresponding to the Nth data is determined based on the N−1th data, the Nth data, and the value of the first signal corresponding to the N−1th data; when the N−1th data is different from the Nth data, the value of the first signal corresponding to the Nth data is equal to the value of the first signal corresponding to the N−1th data; when the N−1th data is the same as the Nth data, the value of the first signal corresponding to the Nth data is different from the value of the first signal corresponding to the N−1th data.
