Abstract

A compound display for presenting images to a viewer is disclosed. The compound display includes first and second displays positioned such that the first display is viewable through the second display when the second display is not generating an image. The first display displays a first image. The second display includes an OLED having a first state in which the OLED generates light of a first intensity and a second state in which the OLED does not generate light. The OLED is transparent to light from the first display when the OLED is not generating light. The second display is positioned between the first display and the viewer. In one embodiment, the first display includes an array of inorganic LEDs that generate light of a greater intensity than that generated by said OLED in said first state.

Claims (9)

a first display for displaying a first image; and

a second display comprising an OLED having a first state in which said OLED generates light of a first intensity and a second state in which said OLED does not generate light, said OLED being transparent to light from said first display when said OLED is not generating light, said second display being positioned between said first display and said viewer.

2. The compound display of claim 1 wherein said first display comprises an array of inorganic LEDs.

3. The compound display of claim 1 further comprising a circular polarizer between said second display and said viewer.
