Abstract
A system and method are disclosed to utilize Gray code in order to reduce the power consumption of column drivers in a display system. Binary source data is received from a timing controller. A Gray code digitizer converts and encodes the binary source data into a binary portion of data and a Gray code data. The binary portion data and the Gray code data are transmitted through a shift register to a digital-to-analog converter. The shift register consumes less power processing the converted binary portion of data and Gray code data than the corresponding binary source data. The digital-to-analog converter decodes the Gray code and generates corresponding gamma voltage levels for display use.
