ABSTRACT:
A display driver includes: a decoder which decodes n-bit (n is an integer greater than one) display data sequentially input from a display memory in units of n bits; a plurality of latch circuits which latch output data of the decoder; an address decoder which generates a latch pulse for the latch circuits to latch output from the decoder; and a plurality of data line driver sections. The n-bit display data is read from the display memory and input to the decoder by performing wordline control once. The decoder decodes the n-bit display data, and sequentially outputs the decoded data to the latch circuits. The address decoder outputs the latch pulse to one of the latch circuits selected based on address information on the display memory when the n-bit display data is read and storage destination designation information arbitrarily set from a control circuit.
