Abstract
A thin-film logic circuit, which can be fabricated entirely of TFTs of the same conductivity type, includes a logic stage connected to a supply voltage and a level shifter connected to a wider voltage range provided by the supply voltage and ground. The logic circuit produces output signals with full rail-to-rail signal range from ground to the supply voltage and can implement or include a basic logic component such as an inverter, a NAND gate, or a NOR gate or more complicated circuits in which many basic logic components are cascaded together. Such logic circuits can be fabricated directly on flexible structures or large areas such as in flat panel displays.
