ABSTRACT:
A digital video display system (100). The system receives digital data from either broadcast video (102) or an alternate source (107), in either analog or digital form. The system processes the data into display data and loads the data onto a digital micromirror device (112). The data is either formatted for color-sequencing or separated into color data for separate devices. The data causes the individual cells on the device to respond and then they are illuminated. The light coming from deflected cells is displayed on a display surface.
