ABSTRACT:
A display driver includes: a parity generation circuit which generates s-bit parity data for n-bit display data input through a processor interface, combines the n-bit display data and the s-bit parity data, and outputs the combined n-bit display data and s-bit parity data to a display memory as (n+s)-bit display data; a parity check circuit which performs data error detection for the (n+s)-bit display data sequentially input from the display memory in units of (n+s) bits, and outputs the n-bit display data; at least one decoder which decodes the n-bit display data output from the parity check circuit; a plurality of latch circuits which latch the data decoded by the decoder; and a plurality of data line driver sections which drive data lines of a display panel based on the data latched by the latch circuits.
