Abstract
A dual layer e-screen includes a top layer of a transparent lenticular or parallax material backed by an e-screen made of a material with controllable grey scales such as electronic paper. The top layer is controllable compensates for ambient lighting by creating a controllable surface that allows for uniform light distribution across the screen, while providing for adaptive contrast levels that selectively darken areas where light is not needed to more accurate display shadows from projected images. The eScreen can be additionally arranged to dynamically alter the gray scale matched to the video being shown to support viewing high dynamic range video through a projector. The gray scale used for each pixel element is biased to the ambient lighting conditions to remove the ambient light from the HDR video playback.
