Classification: CPC H  G | IPC G  H

Claim 4:
5. A sub-pixel circuit formed in a stack, the sub-pixel circuit comprising:
a driving thin film transistor (TFT) comprising:
a source disposed in a buffer layer in the stack;
a drain disposed in the buffer layer in the stack;
a first gate formed in a first inter layer dielectric layer below the buffer layer in the stack; and
a conductive channel formed in a gate insulating layer below the first inter layer dielectric layer in the stack, the conductive channel having a first end and a second end, wherein the first end is electrically coupled to the source and the second end is electrically coupled to the drain;

a switching TFT formed in a second inter layer dielectric layer above the buffer layer in the stack; and
at least one storage capacitor, comprising:
a second gate formed in the first inter layer dielectric layer; and
the source of the driving TFT, the source extending away from the driving TFT in the buffer layer, and overlapping the second gate.
