Abstract

The embodiment of the invention discloses a shift register, a gate drive circuit and a display panel; the shift register comprises: a node adjusting module, wherein the node adjusting module is used for adjusting a first node signal and a second node signal output by the node adjusting module according to a trigger signal and a first clock signal transmitted to the node adjusting module; a following control module which is used for controlling whether the shift signal output by the shift register follows the second clock signal transmitted to the following control module or not according to the first node signal transmitted to the following control module; and a pull-up control module which is used for controlling whether the shift signal output by the shift register follows the power supply signal transmitted to the pull-up control module or not according to the second node signal transmitted to the pull-up control module. According to the technical scheme, the number of the power signal lines in the non-display area of the display panel is reduced, and implementation of a narrow frame of the display panel is facilitated.

Description

Technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a shift register, a gate driving circuit, and a display panel. Background technique [0002] With the development of organic light emitting display technology, organic light emitting display panels are widely used in mobile phones, computers, vehicles and wearable devices due to their advantages of wide color gamut, high contrast, healthy eyes and fast response speed. For devices such as mobile phones and smart watches, narrow bezels have become the mainstream development trend in the display field. [0003] The non-display area of ​​the display panel is provided with a gate drive circuit, and the number of signal lines connected to the gate drive circuit directly affects the area of ​​the frame of the display panel. At present, the shift register in the gate drive circuit generally needs at least two power signals with different levels to realize the st...
