Abstract

A liquid crystal display device employing a multiplexer architecture. The multiplexer device is used to connect three data lines of a data line group to the output of a source driver. The pixel matrix includes pixel rows. In one embodiment, the first and second color pixel circuits in the first and second pixel rows are interleaved; the first color pixel circuit in the second pixel row is adjacent to the second color pixel circuit in the first pixel row; the second color pixel circuit in the second pixel row is adjacent to the first color pixel circuit in the first pixel row; the data polarities of adjacent pixel rows are different. In another embodiment, the first to third pixel rows respectively include a first color pixel circuit, a second color pixel circuit, and a third color pixel circuit; in the first and second pixel rows, pixel circuits corresponding to different data polarities are interleaved.
