A flat panel display comprises a system and a display module. The system comprises an image processing part for deciding a timing format of an image data and generating a control signal for the image data, an encoder for encoding the data and the control signal output from the image processing part in an RSDS specification, and a power output part for outputting a constant-voltage. The display module includes a column driver integrated circuit and a scan driver integrated circuit, and the decoding of the encoded image data and the control signal are performed at a decoder of the column driver integrated circuit and the scan driver integrated circuit.
