Patent ID: 7173611

Claim:
A display system comprising: a display panel including a plurality of pixels, a plurality of data lines, and a plurality of scan lines; a display driver which drives the data lines; and a display controller which supplies display data to the display driver and also controls the display driver, wherein the display controller: includes first to (j+2)th data output terminals (where j is a natural number) for outputting (j+2) bits of display data out of display data that is output in a k-bit unit (where k is an integer such that kâ‰§j+2); outputs display data in a j-bit unit to the display driver through the first to j-th data output terminals; outputs command data for controlling the display driver instead of the (j+1)th bit of display data, through the (j+1)th data output terminal to the display driver; and outputs a command identification signal for identifying the command data instead of the (j+2)th bit of display data, through the (j+2)th data output terminal to the display driver, and wherein the display driver includes: first to j-th data input terminals for inputting display data in a j-bit unit; a latch which fetches the command data that is specified according to the command identification signal; a decoder which decodes the command data fetched into the latch; and a control section which outputs a control signal corresponding to a decoding result by the decoder, the display driver driving the data lines based on the control signal and the display data that has been input through the first to j-th data input terminals.
