Abstract
A display () with enhanced image contrast contains an image-producing component () and a set of shutter strips (). The image-producing component, typically a flat-panel device, has multiple imaging lines that provide light to produce an image. Each shutter strip is situated in front of one or more associated imaging lines. By appropriately switching the shutter strips between light-absorptive and light-transmissive states, the image contrast is enhanced. The shutter strips are typically implemented with a liquid-crystal display structure. The switching of the shutter strips is typically performed with a control component () which utilizes light to control the shutter switching and which is synchronized to signals (or/and) that control the imaging lines.
