Abstract:
A driving method of an electro-optical device provided with a plurality of data lines, a plurality of scanning lines, pixel electrodes corresponding to intersections of said scanning lines and said data lines, and a plurality of signal supply lines corresponding to the scanning lines, the method comprising the steps of:supplying scanning signals respectively for sequentially selecting said scanning lines; sequentially supplying reference signals to the signal supply lines synchronously when said scanning signals become active; supplying pulse width modulation signals respectively that are active only during a period corresponding to a gray scale value indicated by image data to each of the data lines; and capturing reference signals from the signal supply lines corresponding to pixels, and applying the captured reference signals to said pixel electrodes during a period in which the scanning lines and the data lines corresponding to the pixels simultaneously become active at said pixels corresponding to intersections of said scanning lines and said data lines, while holding voltages of the pixel electrodes during a period in which either the scanning lines or the data lines corresponding to said pixels become inactive.
