Patent ID: 8330882

Claim:
An image display, comprising: at least one display device, each of the at least one display device further comprising: a first pair of transparent conductive layers; a second transparent conductive layer spaced apart from the first pair of transparent conductive layers; a display layer disposed between the first pair of transparent conductive layers, the display layer configured to display an image in response to a first set of voltages applied to the first pair of transparent conductive layers; and a light control layer disposed between one of the first pair of transparent conductive layers and the second transparent conductive layer, wherein the display layer is disposed between a viewer and the light control layer, and the light control layer is disposed between a light source and the display layer, the image displayed by the display layer being viewable by the viewer, and the light source being configured to produce an incident light, and wherein the light control layer comprises a polymer-dispersed liquid crystal and is configured to selectively operate in a transmissive mode to allow the incident light to pass through the light control layer toward the display layer, or a reflective mode to reflect the incident light to thereby substantially prevent the incident light from passing through the light control layer toward the display layer, in response to a second set of voltages applied to the one of the first pair of transparent conductive layers and the second transparent conductive layer.
