Abstract
A thin-film transistor array comprises at least first and second transistors. Each of the first and second transistors include a shared silicon layer, i.e., an active layer. The shared semiconductor layer extends continuously between the first and second transistors, and includes a concentration of dopant that increases a resistivity of the semiconductor layer and reduces a leakage current through the semiconductor layer while permitting functioning of the transistor array.
Claims20
A thin-film transistor array comprising at least first and second transistors, each of the first and second transistors comprising:
- a shared semiconductor layer extending continuously between the first and second transistors, and the semiconductor layer doped to increase a resistivity of the semiconductor layer and reduce a leakage current through the semiconductor layer while permitting functioning of the transistor array;
- a source electrode adjacent to the semiconductor layer;
- a drain electrode spaced from the source electrode and adjacent to the semiconductor layer;
- and
- a gate electrode disposed adjacent to the semiconductor layer.
An electronic display comprising:
- a display medium;
- a first pixel electrode and a second pixel electrode provided adjacent to the display medium;
- and
- a first thin-film transistor and a second thin-film transistor in respective electrical communication with the first pixel electrode and the second pixel electrode, and comprising a shared continuous semiconductor layer that provides channels for the first thin-film transistor and the second thin-film transistor, and the semiconductor layer doped to increase a resistivity of the semiconductor layer and reduce a leakage current through the semiconductor layer while permitting functioning of the first and second thin-film transistors.
