3-D DISPLAY USING LED PIXEL LAYERS

摘要

Microscopic LED dice are printed in groups, to form pixels, on a thin transparent substrate, and the LEDs in each pixel are sandwiched between two transparent conductor layers to connect the LEDs in parallel. This forms a single 2-dimensional pixel layer that is substantially transparent, where the pixels are individually addressable. Multiple pixel layers are stacked with an index-matched spacer layer therebetween to form a 3-dimensional array of pixels. If the 3-D display is formed as a cube, the viewing window may be the top pixel layer. All pixel layers are simultaneously viewable through the viewing window since each layer is transparent. Accordingly, 3-dimensional images may be displayed. In another embodiment, one or more LED pixels layers are folded, like an accordion, to achieve a stereoscopic effect so that the left and right eyes see different images to convey depth.

主权项

1. A display device for displaying three-dimensional images comprising:
a plurality of stacked pixel layers, each pixel layer comprising a substantially transparent layer containing addressable light emitting diodes (LEDs) grouped into pixels; and a controller for supplying currents to selected pixels in the stacked pixel layers such that energized pixels in the different pixel layers are simultaneously viewable through a viewing window of the display device to create a three-dimensional image.
