ABSTRACT:
A display driver capable of implementing natural moving image display with a reduced power consumption, based on display data of following frame is generated on a cycle longer than a read cycle for display data from a built-in RAM, and a display unit and an electronic instrument having the display driver. A display driver IC with a built-in RAM stores in an FIFO memory compressed data input on a cycle longer than a drive cycle that is based on the display data, uses an MPEG decoder circuit to decompress the compressed data on a cycle substantially equivalent to the read cycle of the display data RAM to generate the display data, and writes the display data into the display data RAM prior to the read operation at a speed equal to or higher than the reading speed.
