Abstract

A system for displaying images. The system comprises a thin film transistor (TFT) device comprising a substrate having a pixel region. An active layer is disposed on the substrate of the pixel region, comprising a channel region, a pair of source/drain regions separated by the channel region. The channel region comprises dopants with a first conductivity type and a second conductivity type opposite to the first conductivity type. A gate structure is disposed on the active layer, comprising a stack of a gate dielectric layer and a gate layer. A method for fabricating a system for displaying images including the TFT device is also disclosed.
