Patent attributes
A light-emitting diode display device includes a transparent substrate; a plurality of chiplets located over the substrate between a transparent electrode and the substrate, each chiplet including drive circuitry for driving pixels to emit light and 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; 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 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.
