Abstract

In a first preferred embodiment, this invention provides a low cost means for multiplying the resolution of a display. In an iterative process, a DLP projects a first image which is directed to a first quadrant of a display screen, a second image which is directed to a second quadrant of the display screen, a third image which is directed to a third quadrant of the display screen, and a fourth image which is directed to a fourth quadrant of the display screen. Each of the four images comprising a quarter of a full high resolution image which are by this process tiled together to comprise one high resolution image. In a second embodiment, image pixels are steered at the pixel level to comprise a display that can alternately produce a wide range of resolutions on a PDLC in a translucent state or alternately operate as an auto stereoscopic 3D display or alternately operate as a multiple program display enabling multiple users to watch different full resolution programs on the same display concurrently. The 3D and multiple program images being passed through the PDLC caused to be in a transparent state.

Claims

1. A process for displaying high resolution images comprising the steps of:

providing a pixel generation means capable of generating a first number of pixels,

providing a stream of complete image frames wherein each frame comprises a greater number of pixels than said pixel generation means,

providing a modulation means for modulating the direction of pixels generated by said pixel generation means,

providing a display screen,

wherein a first portion of the said image frames are modulated by said modulation means to be incident upon a first portion of said display screen, and wherein a second portion of said image frames are modulated by said modulation means to be incident upon a second portion of said display screen, and whereby the first portion of said image frames and the second portion of said image frame together from a coherent image.

2. The process of claim 1 wherein said image frames are first broken into smaller sections of frames before being modulated to be incident upon a portion of said display screen.

3. A means for displaying a high resolution image comprising a means for scanning a pixel onto a diffuse surface.
