    摘要: Example embodiments relate to thin-film transistors (TFT) and methods for fabricating the same. A thin-film transistor according to example embodiments may include a gate, a gate insulation layer, a channel layer including a first oxide semiconductor layer and a second oxide semiconductor layer, and a source and drain on opposite sides of the channel layer. The first oxide semiconductor layer may have relatively large crystal grains compared to the second oxide semiconductor layer.

    摘要: Example embodiments are directed to a switching device of an active display device and a method of driving the switching device, such that electrical reliability of the active display device is improved. The switching device of the active display device includes a plurality of thin film transistors (TFTs) that are connected in series. Except for a refresh time duration during which the plurality of TFTs of the switching device are simultaneously turned ON, a positive voltage is applied to at least one of the plurality of TFTs of the switching device so that a reliability of the switching device may be improved.

    摘要: A ZnO-based thin film transistor (TFT) is provided herein. Also provided is a method for manufacturing the TFT. The ZnO-based TFT is very sensitive to the oxygen concentration present in a channel layer. In order to prevent damage to a channel layer of a bottom gate TFT, and to avoid a deep negative threshold voltage resulting from damage to the channel layer, the method for manufacturing the ZnO-based TFT comprises formation of an etch stop layer or a passivation layer comprising unstable or incompletely bonded oxygen, and annealing the layers to induce an interfacial reaction between the oxide layer and the channel layer and to reduce the carrier concentration.
