Patent number: 6236385Abstract: A method of driving a liquid crystal that has a memory capability, wherein a reset voltage is initially applied to the liquid crystal during a reset period, to bring about a Freédericksz transition in the liquid crystal. During a subsequent selection period, a selection voltage that is selected on the basis of a critical value that brings about one of two metastable states in the liquid crystal is applied to the liquid crystal, and, during a non-selection period that follows the selection period, a non-selection voltage that is less than or equal to a threshold value that maintains two metastable states is applied to the liquid crystal. A delay period is provided between the reset period and the selection period, in order to gain effective timing for applying the selection voltage to the liquid crystal after the application of the reset voltage has been turned off. This shortens the length of the selection period, and hence the write time.Type: GrantFiled: October 29, 1998Date of Patent: May 22, 2001Assignee: Seiko Epson CorporationInventors: Hiroaki Nomura, Yuzuru Sato, Akira Inoue, Takaaki Tanaka, Kenichi Momose

Patent number: 4850676Abstract: A method and circuits for multiplex driving of a liquid crystal element employing a ferroelectric liquid crystal therein.

Patent number: 4701026Abstract: A method and circuits for multiplex driving of a multielement liquid crystal display device having a ferroelectric liquid crystal therein. The method includes the step of applying at least one selecting electric field pulse having an amplitude which exceeds a threshold value of optical response of the ferroelectric liquid crystal to each element during a selecting term. It further includes the step of applying at least one non-selecting electric field pulse having an amplitude which is no greater than threshold value to each element at a time other than the selecting term. The optical response of the ferroelectric liquid crystal is determined in accordance with waveforms of the selecting and non-selecting pulses. According to the invention the duration of the non-selecting pulses is much smaller than the time between selecting terms. The width of the non-selecting pulses is minimized.Type: GrantFiled: June 11, 1985Date of Patent: October 20, 1987Assignee: Seiko Epson Kabushiki KaishaInventors: Minoru Yazaki, Yuzuru Sato
