Abstract
In a display element using cholesteric liquid crystal, to enable a high-speed partial screen rewrite, a region not to be partially rewritten is scanned in high-speed mode within the tolerance of crosstalk of the liquid crystal, and a region to be partially rewritten is partially rewritten by being scanned at a normal speed within a rewritable range with an inexpensive universal driver. As a result, a high-speed rewrite only to an arbitrary particular region can be made even with an inexpensive universal driver IC.
Claims19
A method of driving a display element that has a plurality of scan electrodes and a plurality of data electrodes, both of those electrodes facing so as to mutually intersect, wherein applying a pulsed driving voltage with a driver IC while selecting the plurality of scan electrodes in an order, comprising:
- scanning a first region to be partially rewritten at a first speed;
- and
- scanning a second region other than the first region at a second speed which is faster than the first speed and at which crosstalk does not occur.
