Abstract
A transparent-reflective display constructed to be alterable so that reflected images are viewed upon a transparent surface that can alter to a darkened surface, thereby changing contrast of the reflection. An assembly consisting of a beamsplitter and an electronically adjustable contrast layer is constructed as a thin sheet and positioned to reflect an image source. The electronically adjustable contrast layer consists of a shuttering capable material, such as liquid crystal shutters and suspended particle devices, that can be electronically engaged to be in a transparent state and also a darkened (opaque) state. The electronically adjustable contrast layer enables images to been seen in a mode that best suits its video content as to the degree of contrast selected among the transparent to darkened states. An embodiment of the present invention synchronizes events in video content to one of the states of transparent, darkened and the increments between.
