Patent ID: 7737939

Claim:
A display driver integrated circuit (IC) comprising: an input unit receiving digital video data to be displayed on a panel; a digital-analog converter converting the digital video data into analog row data and analog column data respectively scanned to row lines and column lines of the panel; and a row data output unit outputting at least one of the row data to a row line corresponding thereto for each row scan clock pulse, wherein the row data output unit activates output paths for outputting the row data to the row lines in an activation order of a driving mode selected from a plurality of driving modes having different orders of activating the output paths in response to a mode select signal, wherein, assuming that groups of three row data respectively correspond to three adjacent row lines of 3n (n is a multiple of 2) row lines represent first through nth row data groups, and output paths for outputting the first through nth row data groups to the row lines represent first through nth output path groups the row data output unit activates at least one of the first through nth output path groups for each row scan clock pulse, and wherein the row data output unit comprises: a plurality of counters respectively corresponding to the plurality of driving modes, each driving mode corresponding to a respective activation order; and a decoder activating output path groups corresponding to numbers representing the activation order, which are output from a counter selected from the plurality of counters, wherein one of the plurality of counters is selected in response to the mode select signal.
