High contrast liquid crystal display

摘要

A projection system including a first imager that is an organic light emitting diode (OLED) imager configured to modulate a light band on a pixel-by-pixel basis proportional to gray scale values provided for each pixel of the image to provide a first output matrix and a second imager positioned and configured to receive the first output matrix of modulated pixels of light from the first imager on a pixel-by-pixel basis proportional to a second gray scale value provided for each pixel of the image is disclosed.
