Abstract:

The report describes the development of a Liquid Crystal 3-D Display. The display consists of a stack of ten cholesteric-nematic liquid crystal cells. Each cell consists of a matrix of 20 x 40 addressable elements, 0.15 x 0.15 inches per element, with a total active display area of 3 x 6 inches. The modified half select matrix addressing scheme provides for up to four levels of gray scale.
