    Abstract: A flexible light sheet includes a bottom conductor layer overlying a flexible substrate. An array of vertical light emitting diodes (VLEDs) is printed as an ink over the bottom conductor layer so that bottom electrodes of the VLEDs electrically contact the bottom conductor layer. A top electrode of the VLEDs is formed of a first transparent conductor layer, and a temporary hydrophobic layer is formed over the first transparent conductor layer. A dielectric material is deposited between the VLEDs but is automatically de-wetted off the hydrophobic layer. The hydrophobic layer is then removed, and a second transparent conductor layer is deposited to electrically contact the top electrode of the VLEDs. The VLEDs can be made less than 10 microns in diameter since no top metal bump electrode is used. The VLEDs are illuminated by a voltage differential between the bottom conductor layer and the second transparent conductor layer.

    Abstract: A flexible light sheet lamp includes a thin substrate and an array of printed microscopic vertical LEDs (VLEDs) sandwiched between a transparent first conductor layer and a transparent second conductor layer. The light sheet has a light exit surface. The VLEDs have one surface, facing the light exit surface of the light sheet, covered with a reflective metal. A phosphor layer is provided such that the semi-transparent VLED layer is between the phosphor layer and the light exit surface. A reflector layer is provided such that the phosphor layer is between the reflector layer and the VLED layer. The substrate may form the light exit surface or the light exit surface may be the opposite side of the light sheet. Some VLED light passing through the phosphor layer is reflected by the reflector layer and re-enters the phosphor layer. Therefore, less phosphor is needed to achieve the desired conversion ratio.

    Abstract: Ultra-thin flexible LED lamp layers are formed over a release layer on a substrate. The LED lamp layers include a first conductor layer overlying the release layer, an array of vertical light emitting diodes (VLEDs) printed over the first conductor layer, where the VLEDs have a bottom electrode electrically contacting the first conductor layer, and a second conductor layer overlying the VLEDs and contacting a top electrode of the VLEDs. Other layers may be formed, such as protective layers, reflective layers, and phosphor layers. The LED lamp layers are then peeled off the substrate, wherein the release layer provides a weak adherence between the substrate and the LED lamp layers to allow the LED lamp layers to be separated from the substrate without damage. The resulting LED lamp layers are extremely flexible, enabling the LED lamp layers to be adhered to flexible target surfaces including clothing.
