Patent ID: 7724230

Claim:
A driving circuit of a display device, comprising: a timing controller for combining red color, green color and blue color digital data signals corresponding to colors for displaying images to generate first and second combined digital data signals and for supplying the first and second combined digital data signals to first and second data transmission lines, respectively; and a plurality of data driver integrated circuits for processing the first and second combined digital data signals from the timing controller to restore the red color, green color and blue color digital data signals, converting the restored red color, green color and blue color digital data signals into analog data signals, and supplying the analog data signals to a display panel; wherein the first combined digital data signal is generated by combining all bits of the red color signal with first bits of the blue color digital data signal, and the second combined digital data signal is generated by combining all bits of the green color digital data signal with second bits of the blue color digital data signal.
