Abstract:
A cholesteric liquid crystal writing board, which can display a writing track, includes a cholesteric liquid crystal device, an optical layer, a photo-sensing array and a voltage control circuit. The cholesteric liquid crystal device includes plural liquid crystal control areas. The optical layer has plural optical openings. The photo-sensing array includes plural photo sensors arranged in an array. The photo sensors are disposed corresponding to the optical openings. One of the photo sensors senses a luminous flux change and generates an erasing signal accordingly. The voltage control circuit receives the erasing signal and outputs a voltage signal accordingly to the liquid crystal control areas corresponding to the photo sensors having the luminous flux change, such that a part or all of cholesteric liquid crystals corresponding to the liquid crystal control areas are morphologically changed so as to clear a part or all of the writing trace.

Claim (Index 13):
The cholesteric liquid crystal writing board according to  claim 1 , wherein a light irradiates the light-entering surface of the cholesteric liquid crystal device to generate the luminous flux change, and the erasing signal comprises position information regarding to where the cholesteric liquid crystal device is irradiated by the light.
