Abstract: A flexible light sheet includes a thin substrate that allows light to pass through it, a transparent first conductor layer overlying the substrate, an array of vertical light emitting diodes (VLEDs) printed as an ink over the first conductor layer, each of the VLEDs having a bottom electrode electrically contacting the first conductor layer, a dielectric material between the VLEDs overlying the first conductor layer, and a transparent second conductor layer overlying the VLEDs and dielectric layer, each of the VLEDs having a top electrode electrically contacting the transparent second conductor layer. Each individual VLED may emit light bidirectionally. The VLEDs are illuminated by a voltage differential between the first conductor layer and the second conductor layer such that bidirectional light passes through the first conductor layer and the second conductor layer. Phosphor layers may be deposited on both sides to create white light using blue VLEDs.
