Patent ID: 7030852

Claim:
A liquid crystal display (LCD) unit, comprising: an LCD panel; a plurality of source drivers functionally divided into first and second source driver groups which are respectively assigned to first and second halves of the LCD panel; and a pixel data rearrangement circuit preceding the first and second source driver groups, the pixel data rearrangement circuit simultaneously receiving 2N-path (N is a natural number) pixel data and rearranging the orders of the 2N-path pixel data according to a predetermined data format and applying rearranged first N-path pixel data to the first source driver group and applying rearranged second N-path pixel data to the second source driver group, wherein the pixel data rearrangement circuit comprises, memory means having a plurality of line memories into which the 2N-path pixel data are stored; first switch means for selectively reading the 2N-path pixel data from the line memories under control of switch control signals; and second switch means for rearranging the orders of the 2N-path pixel data selectively read out of the line memories.
