Title: Drive method of electro-optical device, and electro- optical device and electronic equipment using the method
Inventor: NAKANISHI HAYATO
IPC: H05B44/00
Filed: 2001-05-10
Abstract: PROBLEM TO BE SOLVED: To fully write in analog image signals, even in a high precision made and to maintain reliability in a liquid crystal display device, in which analog image signals are supplied to pixel electrodes while the polarities are varied. SOLUTION: An analog switch ASWn selectively connects signal lines 30, to which analog image signals Vid are supplied, and data lines ϕDn that constitute an image display section 60. Data line selection signals ΦHn control the switch ASWn to conductive and/or conductive states. When the signals Vid have positive polarities, H level potential and L level potential of the signals ΦHn are both made to be higher for same potential than the case of negative polarities. Since the potential of the signals ΦHn applied to a gate electrode of the switch ASWn is raised, the resistance of the switch ASWn is becomes small, and the write time for the lines ϕDn can be shortened. Moreover since, the voltage which acts on the switch ASWn does not change, its reliability is maintained.
