Abstract

The invention provides a driving circuit, a driving method and a display device. The driving circuit comprises a first driving signal generating circuit and a second driving signal generating circuit; and the second driving signal generation circuit controls the potential of a third node according to the first initial voltage signal and the potential of the second node, and controls the second driving signal output end to output a driving signal under the control of the potential of the first node and the potential of the third node. By adding the second driving signal generation circuit, a high-level effective driving signal and a low-level effective driving signal can be generated at the same time through one driving circuit, the driving signals can be provided for an LTPO (Low Temperature Polycrystalline Oxide) pixel circuit through one driving circuit, the number of adopted transistors is small, and realization of a narrow frame is facilitated.

Description

Technical field [0001] The present invention relates to display technology, and particularly relates to a circuit and method for driving a display device driving. Background technique [0002] In the low frequency drive display application technology, each pixel circuit may include different types of transistors. For example, the display device each pixel circuit may include not only a low temperature polysilicon thin film transistor, a thin film transistor and may include an oxide. Display scan driver device should include not only may produce an active low scan signal for low-temperature polysilicon thin film transistor, but also should include an effective scan can produce a high level signal for an oxide thin film transistor. Conventional scan driver driving circuits need two scan signal generated active high and active low scan signal, the number of transistors used in more unfavorable to narrow the frame. Inventive content [0003] The main object of the present invention ...
