Abstract: 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.

Abstract: Various applications and customizations of a thin flexible LED light sheet are described. Microscopic LED dice are printed on a thin substrate, and the LEDs are sandwiched between two conductor layers to connect the LEDs in parallel. The conductor layer on the light emitting side is transparent. In one embodiment, the light sheet is applied to the bottom surface of a controllable display to serve as a backlight. In another embodiment, the light sheet is applied to the edge of a leaky light guide for backlighting. In another embodiment, a thin light-emitting edge of the light sheet is coupled to the edge of the leaky light guide for backlighting. In another embodiment, the light sheet is affixed to a medical instrument, and light is emitted from a thin light-emitting edge of the light sheet. In one embodiment, the light sheet is optically coupled to an optical fiber.
