Abstract
An image display comprises at least one display device having a first pair of transparent conductive layers, a second pair of transparent conductive layers spaced apart from the first pair 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 the second pair of transparent conductive layers, the light control layer configured to operate in one of a transmissive mode to allow an incident light to pass toward the display layer and a reflective mode to reflect an incident light away from the display layer in response to a second set of voltages applied to the second pair of transparent conductive layers.
