Electro-optical device, driving circuit and driving method of electro-optical device, and electronic apparatus

摘要

Lamp wave signals are supplied to signal supply lines via switches. The switches are turned ON when their corresponding scanning lines are selected. Hence, a load on the driving circuit for the lamp wave signals will be a parasitic capacitance that comes from a single signal supply line. PWM signals of having pulse widths based on image data are supplied to data lines. A TFT supplies PWM signals to a gate electrode of a TFT when a corresponding scanning line is selected; therefore, the lamp wave signal is applied to a pixel electrode via the TFT when the data line and the scanning line simultaneously become active.
