Abstract
A controller includes a register storing a group of parameters including a driving-control parameter for controlling a data line driving circuit and a scanning line driving circuit, a parameter controller for updating values of the group of parameters stored in the register and for initializing the values of the group of parameters stored in the register when a reset signal RES is input, and a driving controller for controlling a data line driving circuit and a scanning line driving circuit in accordance with the driving-control parameter stored in the register. The driving controller controls the data line driving circuit and the scanning line driving circuit such that turn-off voltage is applied to a plurality of pixels after the parameter controller updates the values of the group of parameters by the reset signal.
