US 2006/0214169 A1 · Active Matrix Display Backplane

Abstract

A matrix display driver comprises a flexible substrate, a gate line arranged linearly along one surface of the substrate, a source line arranged perpendicularly to the gate line but on the opposed surface of the substrate, the relative overlap of the gate line and source line defining a display switch, which further includes a pixel electrode, a drain electrically connected to the pixel electrode, a semiconductor disposed between the source line and the drain, and a channel gate, the channel gate electrically connected to the gate line by a via defined through the substrate, the channel gate being electrically insulated from the semiconductor by a dielectric, and wherein, when the display switch is actuated, current flows to the drain and the pixel electrode is energized. In an alternative embodiment, the source lines and gate lines are disposed in parallel on the same surface of the substrate.
