SOURCE DRIVE CIRCUIT

摘要

A source drive circuit. At least four channels of all source line control channels in an array substrate are driven by the circuit, and sharing of two DACs (Digital Analog Converter) by every four channels can be realized by means of technical means for frequency doubling of input signals and for time sharing multiplexing of the DACs; thus, the number of the DACs in the source drive circuit is effectively reduced, area and resources occupied by the DACs as well as circuit cost are lowered, chip volume is further advantageously diminished, and higher resolutions can be accomplished on an unchanged chip area.
