PROJECTION SYSTEM

摘要

PURPOSE: A projection system is provided to reduce a manufacturing cost and to increase the contrast ratio of a screen by forming a white area of a screen. CONSTITUTION: An upper translucent substrate of a PDLCoS(Polymer Dispersed Liquid Crystal on Silicon) display(200) is faced with a lower silicon substrate. A liquid crystal structure is arranged between the lower silicon substrate and the upper translucent substrate. The polymer dispersed liquid crystal silicon display reflects and disperses light from light source. A reflective mirror(300) reflects the light from the PDLCoS display.
