Abstract: A display unit is provided. The display unit includes a multiplexer circuit, a latch circuit, and a liquid crystal capacitor. The multiplexer circuit receives a plurality of voltages. The plurality of voltages at least comprises a first voltage and a second voltage. The latch circuit receives a driving signal and a first data signal. When the driving signal is at an asserted state, the latch circuit controls the multiplexer circuit according to the first data signal to select the first voltage or the second voltage to serve as a display voltage. The liquid crystal capacitor receives the display voltage. The liquid crystal capacitor has a plurality of liquid crystal molecules, and an optical state of the plurality of liquid crystal molecules is determined according to the display voltage.

Abstract: This invention provides a driving circuit for simultaneously driving three-color bistable liquid crystals, which employs a voltage-shift circuit to provide different-color bistable liquid crystals with respective level-shift voltages. A grey-scale voltage is respectively added to the respective level-shift voltages. By this invention, the whole grey-scale voltages are capable of falling in the voltage ranges for displaying grey scales for the different-color bistable liquid crystals. The grey-scale display can be optimized.
