Patent ID: 7994714

Claim:
A light-emitting diode display device, comprising: a) a transparent substrate; b) a plurality of pixels formed on the substrate, each pixel including a transparent electrode formed over the transparent substrate, one or more layers of light-emitting material formed over the transparent electrode, and an electrode formed over the one or more layers of light-emitting material; c) a plurality of chiplets located over the substrate between the transparent electrode and the substrate, each chiplet including drive circuitry for driving the pixel to emit light, the drive circuitry including a storage capacitor for storing charge and wherein light illumination of at least a portion of the drive circuit causes the capacitor to leak charge; d) a connection pad forming a first light shield separate from the drive circuitry located on the surface of each chiplet disposed over the drive circuitry and substantially shielding at least a portion of the drive circuitry from illumination, the connection pad electrically connected to the drive circuitry; and e) a second light shield disposed under the drive circuitry between the drive circuitry and the substrate to shield at least a portion of the drive circuitry from illumination, wherein the second light shield includes a black material layer applied to the side of the chiplets between the drive circuitry and the substrate.
