Abstract
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.
Claims8
An image projection system for projecting an image comprising a matrix of light pixels having modulated luminance, the projection system comprising:
- a first imager configured to modulate light 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 and modulate the individual modulated pixels of light from said first imager on a pixel-by-pixel basis proportional to a second gray scale vale provided for each pixel of said image, wherein one of said first imager and said second imager is an organic light emitting diode (OLED) imager.
