Abstract
A cholesteric liquid crystal (ChLC) display and driving method thereof are provided. The ChLC display has a driving circuit for providing voltage on a scan line and a data line so as to drive a pixel. The driving circuit provides a first voltage and a second voltage to the data and the scan lines during a first time period, a third voltage to the data line and/or a fourth voltage to the scan line during a second time period, a fifth voltage and a sixth voltage to the data and the scan lines during a third time period. The first and sixth voltages are high levels, the second and fifth voltages are low levels, the levels of the third and fourth voltages are between the high and low levels.
