Claim:
1. A panel driver integrated circuit (IC), comprising: a data encoder receiving an original data and selectively performing an encoding operation, wherein the encoding operation changes the original data to serve as an output data of the data encoder according to a data mapping table; a level shifter having an input terminal coupled to the data encoder to receive the output data; a digital-to-analog converter (DAC) having a data input terminal coupled to an output terminal of the level shifter; a rearrangement circuit having a plurality of output terminals coupled to a plurality of reference voltage input terminals of the DAC to provide a plurality of reference voltages, wherein the rearrangement circuit rearranges an order of the reference voltages according to the encoding operation of the data encoder; and an output buffer having an input terminal coupled to an output terminal of the DAC.
