Abstract
This application describes a light emitting device or an assembly of light emitting devices. In the completed device, an LED at least partially overlies a thin film transistor and a reflective layer is disposed between the LED and the thin film transistor. Methods to fabricate such devices and assemblies of devices are also described.
Claims23
A light emitting device comprising:
- a thin film transistor;
- an LED having a surface area, wherein the LED at least partially overlies the transistor and wherein the LED comprises GaP, AlGaAs, GaAsP, AlGaP, GaInP, InGaN, AlGaN, AlN, InN, or InP;
- a reflective layer disposed between the thin film transistor and the LED;
- and a backboard comprising an interposer, wherein the interposer comprises a plurality of metal wires.
