IPC: G09G3/36
Filed: 2003-06-16
Abstract: <P>PROBLEM TO BE SOLVED: To overcome the disadvantage that response speed is low and moving picture blur is generated when a high speed image is displayed in a twisted nematic liquid crystal of a TN mode, etc.  <P>SOLUTION: The response speed of the liquid crystal when applied voltage is turned off is made higher by specifying the relationship between the twist pitch p and gap d of the twisted liquid crystal to be p/d<8 and further performing polymer stabilization to perform high speed stabilization for increasing the torque when the liquid crystal returns to the alignment which is present when no voltage is applied. High response speed can be obtained even when a TN liquid crystal is used by applying this technique to the liquid crystal display device which is driven by a reset, overdrive or common modulation. As a result, this technique can deal with field sequential display to which higher response speed is required.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
