Abstract:
1. A display driving integrated circuit (IC) receiving M-bit gray-scale data to represent a gray scale of one pixel and driving a panel including a plurality of pixels, comprising: a memory that stores gray-scale data representing gray scales of the plurality of pixels; a source driver that receives the gray-scale data in parallel from the memory through transmission lines; at least one multiplexer to transmit the M-bit gray-scale data representing the gray scale of one pixel time divided bit by bit through L transmission lines, wherein the value of L is smaller than the value of M, at least one demultiplexer that receives gray-scale data time divided bit by bit through the L transmission lines, that demultiplexes the received gray-scale data into M-bit gray-scale data and that transmits the M-bit gray-scale data to the source driver; and a control signal generator that generates control signals that control at least one of the multiplexer and the demultiplexer; wherein:
