Embodiment Construction

[0027] The embodiment of the present invention provides a driving method, device and display device for a display device. When the current driving current is less than the threshold current, the duration of the periodic signal in the current driving signal is at a high level, or the current The voltage of the high-level signal in the driving signal; the adjusted driving signal is used to drive the gate driving circuit, therefore, the time for the shift register unit receiving the adjusted driving signal to output a high level will be longer, The number of shift register units that can be turned on in the gate driving circuit increases, thus reducing the probability of a white screen or a black screen of the display device at low temperature. Wherein, the driving signal is used to drive the gate driving circuit of the display device to be turned on step by step.

Abstract

The embodiment of the invention provides a driving method and device of a display device and a display facility. The driving method and device of the display device and the display facility are used for solving the problem that in an existing gate driving circuit, due to the fact that both startup current and leakage current in the turn-off process of an ASG TFT can gradually decrease as the temperature drops, a display facility may have a white screen or a black screen. The driving method comprises the steps that it is determined that the amplitude of current driving current is smaller than that of threshold current, wherein the driving current is current used for driving a display screen in the display device to work; the time of a periodical signal, in a high-level state, in the current driving signal is prolonged, or the voltage of a high-level signal in the current driving signal is boosted; the adjusted driving signal is used for driving the gate driving circuit, wherein the driving signal is used for driving the gate driving circuit of the display device to be opened step by step.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method, device and display device of a display device. Background technique [0002] Liquid crystal displays (liquid crystal displays, LCDs) or organic light-emitting diodes (Organic Light-Emitting Diodes, OLEDs) are currently widely used in notebook computers, personal digital assistants (Personal Digital Assistant, PDA), flat-screen TVs, or mobile phones, etc. information products. Traditional liquid crystal displays use external driver chips to drive the chips on the panel to display images, but in order to reduce the number of components and reduce manufacturing costs, in recent years, it has gradually developed to directly fabricate the driver circuit structure on the display panel, such as using gate drive A technology in which a circuit (gate driver) is integrated into a liquid crystal panel (Gate On Array, GOA). [0003] The current gate driving circu...
