ELECTRO-OPTICAL DEVICE, METHOD OF CONTROLLING ELECTRO-OPTICAL DEVICE, AND ELECTRONIC INSTRUMENT

摘要

An electro-optical device includes a data line driving circuit that supplies a video signal, in which a data voltage having magnitude of voltage applied to the data lines in the amount of k (k>1) in accordance with an input video divided into frames is subjected to time division multiplexing, to a signal line, a selection circuit that selects at least one data line which becomes a supply destination of the video signal supplied to the signal line, a scanning line driving circuit that selects at least one scanning line, a control circuit that controls a predetermined precharge voltage to be applied to the data lines in the amount of k in the precharge time period, and a correction circuit that corrects a gradation level difference between the pixel applied with the precharge voltage and the pixel applied with no precharge voltage.
