Display device and driving method thereof |
摘要 |
The present invention relates to a display device and a driving method thereof. A display device in the present invention comprises: a capacitor connected between a first node and a second node; a switching transistor controlled by a first scanning signal and transmitting a data voltage to the first node; an emission control transistor controlled by a second scanning signal and transmitting a reference voltage to the second node; a driving transistor comprising a control terminal connected to the first node, an output terminal connected to the second node, and an input terminal; a driving control transistor controlled by a third scanning signal and transmitting a driving voltage to the input terminal of the driving transistor; and a light-emitting device connected to the second node. Accordingly, display contrast of a display device may be improved.
