| titleOfInvention | Optically writing projection-type display |
| abstract | An optically writing projection-type display in which two-dimensional information such as an image and a data pattern is input to a space-light modulation element (1) using writing light, and the information is two-dimensionally displayed on a screen (14) using display light (12). The optically writing space-light modulation element (1) is in close contact with the fiber plate (2) on a cathode-ray tube (3), and consists of a laminate and two transparent electrodes (15) sandwiching the laminate. The laminate comprises a nematic, cholesteric, or smectic liquid crystal (22), a liquid crystal composite (18), a dielectric multilayer mirror (17) reflecting light almost totally, an insulating light-absorbing layer (170) absorbing light having slightly transmitted the mirror (17), and a photoconductive layer (16) in this order. The liquid crystal composite (18) is so made that the same liquid crystal as the liquid crystal (22) is dispersed and confined in a resin matrix (23) having a refractive index equal to any one of the refractive index of ordinary or extraordinary ray of the liquid crystal or the refractive index of the liquid crystal randomly oriented, or that the resin matrix is dispersed and confined in the liquid crystal. The projection light (13) is projected on the screen (14) using a white light source (4) for display and a projection optical system (6, 7, 8, 8', 9, 6', 6'', 10). A bright display image is displayed since neither a polarizing plate nor an analyzing plate is used. The device exhibits excellent space uniformity of a displayed image, quick response and high contrast. An analog image can be easily displayed. A moving image can be displayed by using a Schlieren optical system. |
