ABSTRACT:
A liquid crystal display (LCD) source driving circuit having a reduced circuit footprint. A plurality of the LCD source driving circuits are typically disposed along a side of an LCD panel and drives the LCD panel in response to digital image signals, such as color signals R, G, B, and control signals received from a control circuit. Also, the LCD source driving circuit includes a plurality of latch circuits, a plurality of level shifters, a plurality of Positive voltage digital-to-analog decoders, a plurality of Negative voltage digital-to-analog decoders, a plurality of multiplexor (MUX) circuits, and a plurality of amplifiers. Thus, the LCD source driving circuit is capable of selectively latching digital image signals using the latch circuits with MUX circuit functions, thereby reducing the circuit footprint of source vertical channels within the LCD source driving circuit.
