Dual view display
View Patent ↗A dual view or two-sided display system to display two different images in substantially opposite direction using a single transparent display to time-multiplex the images and two shutter devices to alternately block each side from being viewed according to the image being displayed. The system includes reflective devices between each side of the transparent display and the two shutter devices so light can be reflected from one side of the transparent display to the other side of the transparent display in order to supplement the light intensity of the image being displayed.
1. A dual view display system for displaying images formed of light in substantially opposite directions, said system comprising:
a transparent display configured to emit light from a first side in a first direction and emit light from a second side substantially opposite the first side in a second direction substantially opposite the first direction;
a first shutter device overlying the first side of the transparent display, said first shutter device operable to a transparent mode whereby light emitted in the first direction by the transparent display passes through the first shutter device, and operable to an opaque mode whereby light emitted in the first direction by the transparent display is obstructed from passing through the first shutter device; and
a first reflective device interposed between the transparent display and the first shutter device, said first reflective device operable to a transparent mode whereby light emitted in the first direction by the transparent display passes through the first reflective device toward the first shutter device, and operable to a reflective mode whereby light emitted in the first direction by the transparent display is reflected through the transparent display into the second direction, thereby supplementing light emitted in the second direction by the transparent display.
2. The system in accordance with claim 1 , wherein said transparent display comprises an organic light emitting diode (OLED).
3. The system in accordance with claim 1 , wherein said first shutter device comprises an electrowetting element that includes an opaque oil layer.
4. The system in accordance with claim 1 , wherein said first reflective device comprises an electrowetting element that includes a Galistan layer.
5. The system in accordance with claim 1 , wherein said system further comprises
a second shutter device overlying the second side of the transparent display; and
a second reflective device interposed between the transparent display and the second shutter device.
