Title: Liquid crystal display
Inventor: NAKANO TAKETOSHI
IPC: G02F1/133
Filed: 2002-11-19
Abstract: A liquid crystal panel has pixel-forming portions driven by the same scanning signal line Lg. The pixel-forming portions are assigned dispersedly to two mutually adjacent rows of pixels sandwiching the scanning signal line Lg from above and below, in a horizontally periodical pattern having a cycle of "up, down, up" or "down, up, down" as to which of the up row and the down row is selected in the assignment of three pixel electrodes. The liquid crystal panel having a three-column-cycle staggered structure such as the above, is driven by a column electrode driving circuit built for a 1-H inversion driving method, whereby a quasi dot inversion driving is achieved. Alternatively to the -three-column-cycle staggered structure, the liquid crystal panel may have a twelve-column-cycle staggered structure, in which the horizontally periodical pattern has a cycle of "up, down, up, down, up, down, down, up, down, up, down, up" or "down, up, down, up, down, up, up, down, up, down, up, down" as to which of the up row and the down row is selected in the assignment of twelve pixel electrodes. A staggered structure such as the three-column-cycle and the twelve-column-cycle staggered structure enables a quasi dot inversion driving method while reducing vertical shadow when displaying e.g. the "checker back".

Filed: 2002-12-26
Abstract: A series quaternary alkylammonium salts used in the organophilic procedure, performed on montmorillonite clay, resulting in intercalation in plasticizer between the polymer and the organophilic clay. A series of gel polymer nanocomposite electrolyte materials were successfully prepared by adding the appropriate percentage of plasticizer, organophilic clay and lithium perchlorate to polymer. The best possible ionic conductivity was 1.03x10<SP>-2</SP> S/cm and exhibited better film formation, plasticizer-maintaining capability and dimensional stability than the electrolyte film without the added organophilic clays. From the cyclic electrochemistry testing result, it is shown that adding organophilic clays significantly enhances the electrochemical stability of the gel polymer electrolyte system. The invention also concerns the lithium rechargeable battery which assembled with gel (nanocompsite polymer electrolytes. Such lithium rechargeable batteries has the stable cyclic charge-rechargeable property and potential great commercial value.
