Color projection system

摘要

A projection system for projection of a color image according to the application, especially a front or rear projection TV according to the invention, comprises a light source for providing light to an array of micromirrors, especially an arc lamp; an array of micromirrors, each micromirror having a substantially four-sided shape; and a screen on which an image to be viewed is displayed. Light from the light source is incident on the array of micromirrors during operation and is directed as a rectangular image to the screen.The micromirrors are capable of movement between an OFF state and an ON state by pulse width modulation to achieve a gray scale image on the screen. Each micromirror corresponds to a pixel in a viewed image on the screen. The viewed image has four sides and there are no pixel sides in the viewed image that are parallel to any image sides.
