PROBLEM TO BE SOLVED: To provide a display system and a display controller that can perform control by command data by using a general controller. SOLUTION: The controller 50 outputs display data in j-bit units through 1st to (j)th data output terminals and command data for controlling a data line driving circuit 30 through a (j+1)th data output terminal. Further, a command discrimination signal for discriminating the command data is outputted to the data line driving circuit 30 through a (j+2)th data output terminal. The data line driving circuit 30 includes a latch which receives command data specified according to the command identification signal, a decoder which decodes the received command data, and a control part which outputs a control signal corresponding to the decoding result of the decoder, and drives a plurality of data lines of a liquid crystal panel according to the control signal.
