Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] like figure 1 As shown, the shift register described in the embodiment of the present invention has a DC injection test function, including:

[0035] Shift register body 10;

[0036] Gate drive signal output terminal Gate-out;

[0037] DC test signal writing terminal C; and,

[0038] The DC injection test control unit 11 is respectively connected to the output terminal of the shift register body 10, the gate drive signal output terminal Gate-out, and...

Abstract

The invention provides a shift register, a driving method, a GOA circuit (a gate drive circuit manufactured on an array substrate) and a display device. The shift register comprises a shift register body, a gate driving signal output end, a direct current test signal writing end, and a direct current injection test control unit which is used for controlling the direct current test signal writing end to connect the gate driving signal output end in a direct current injection test period and controlling the direct current test voltage signal written by the direct current test signal writing end to be not coupled to the shift register body. According to the shift register, the driving method, the GOA circuit and the display device, the adjustable input of a gate direct current signal can be carried out in a direct current injection test period.

Description

technical field [0001] The present invention relates to the technical field of DC injection testing, in particular to a shift register, a driving method, a GOA (Gate On Array, a gate driving circuit fabricated on an array substrate) circuit and a display device. Background technique [0002] GOA circuits (Gate On Array, gate drive circuits fabricated on array substrates) are widely used to reduce costs and prepare products with narrow borders. However, since there is no Bonding (binding) area, it is not possible to conduct adjustable Gate (gate) DC injection analysis (the shift registers at all levels included in the GOA circuit can only perform high-level injection, and cannot Adjustment), which greatly limits the bad analysis process of the Panel (display panel). Contents of the invention [0003] The main purpose of the present invention is to provide a shift register, a driving method, a GOA circuit and a display device, so as to solve the problem that the existing GO...
