Research Statement
Recent improvements in liquid crystal display (LCD) panels for multimedia and medical products allow higher definition and greater color depth. Achieving the higher color depths that LCD drivers can produce requires a higher resolution in digital-to-analog converters (DACs) and a larger die area of the circuit. In today’s mature LCD market means, there is a high demand for low-cost, high-performance driver integrated circuits (ICs). An LCD driving system typically comprises a timing controller, column drivers, gate drivers, and a reference source. An LCD module often includes several column-driver and gate-driver ICs. The die area of a column driver is much larger than that of a gate driver, as a column driver generally includes shift registers, input registers, data latches, level shifters, DACs, and output buffers. Among these components, DACs occupy the largest die area. Thus, to reduce the cost of column-driver ICs, the die area of DACs should be reduced.
