发明名称 Non-speckle liquid crystal projection display
摘要 A non-speckle laser projection display composed of a liquid crystal material for the generation of a high resolution, non-speckle image. The projection display screen includes a liquid crystal material which is constructed in a highly scattered state when no drive voltage is applied. When a high frequency, low voltage signal is applied to the liquid crystal projection display screen, the liquid crystal molecules vibrate slightly at a frequency higher than 60 Hz, thereby causing the speckle pattern to change quickly, and causing the eye to smooth out and see no speckle. In addition, provided is a non-speckle laser display system in which included is a laser image source and the liquid crystal projection display screen.
