Embodiment Construction

[0078] The invention mainly provides a bistable anti-chiral nematic liquid crystal display and an active driving method thereof. Each pixel of the bistable chiral nematic liquid crystal display includes at least one transistor as a switch for inputting a row voltage to the pixel. The pixel may also include a capacitor for storing the voltage of the pixel. The panel of the bistable chiral nematic liquid crystal display includes a pixel circuit for driving the display, and the data signal enters a selector from the data bus, and the selector selects an input terminal composed of at least one fixed voltage and a data signal from the control signal terminal. One of the signals is an output signal, which is used as a row voltage for driving the chiral nematic liquid crystal. At the same time, the common electrode at the other end of the pixel is applied with an appropriate voltage to control the steady state of the chiral nematic liquid crystal of the pixel.
