Abstract:
An electronic display drive circuit comprising:a pixel electrode; a data line electrode; an insulator disposed adjacent the pixel electrode; and a transistor placed adjacent the insulator on a side thereof opposite the pixel electrode for addressing the pixel electrode, the transistor comprising a channel defined by a source electrode and a drain electrode, the channel having a length, L, defined as a distance between the source and drain electrodes, and a channel width, W, defined as an effective lateral length measured along the source and drain electrodes, the transistor further comprising a semiconductor layer adjacent the pixel electrode and the data line electrode, a gate electrode and a gate dielectric separating the semiconductor layer from the gate electrode; wherein the channel has a non-rectangular shape that allows a greater channel length than a rectangular channel between the source and drain electrodes, the pixel electrode covers at least most of the channel, and the insulator insulates the source electrode and the drain electrode of the transistor from the pixel electrode except for a region of electrical contact between the source electrode of the transistor and the pixel electrode.
