Abstract

PURPOSE:To considerably improve voltage margin being the disadvantage of a bias method by respectively applying such voltages at which the digit-segment voltages during selecting period become V and those during non-selecting period become alternating electric fields with 1/2V thereby driving liquid crystal.
