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.
