Abstract

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.
