Abstract

A liquid crystal display driver includes a shift register for shifting stored R, G and B data and outputting load signals, a first latch having a plurality of channels for holding and outputting the R, G and B data, a bit converter for converting a number of bits of each R, G and B data outputted from the first latch, a multiplexer for selectively passing voltages outputted by the bit converter upon application of the load signals outputted by the shift register, a decoder for selecting and sequentially outputting an externally supplied voltage in response to an output of the multiplexer, a demultiplexer for demultiplexing output signals of the decoder upon application of the load signals, a second latch for storing and outputting output signals of the demultiplexer,and an output buffer for transmitting output signals of the second latch to a liquid crystal display panel.
