Embodiment Construction

[0048] 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.

[0049]As mentioned in the background, the existing gate driving circuit is composed of a multi-stage shift register, and the turn-on signal is transmitted to the scanning lines step by step through the shift register. However, since the shift register consists of many components and occupies a large layout area, the frame of the existing display device is relatively wide, which does not conform to the current development trend of narrow frame of the display dev...

Abstract

The invention discloses a scanning circuit, a gate drive circuit and a display device, the scanning circuit is used for scanning an n-level gate line, the scanning circuit comprises: a first clock signal end to an m-th clock signal end, a signal control unit, a latch unit and a first output unit to an n-th output unit; wherein, according to the control of m clock signal ends, the signal control unit is controlled to output an open signal to the latch unit, the latch unit is controlled to latch the open signal and output to the output units, n output units are controlled to output the open signal in sequence to complete the scanning, the scanning circuit has simple structure, the occupied layout area is small, and the above characteristics are good for the narrow bezel design of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, more specifically, to a scanning circuit, a gate driving circuit and a display device. Background technique [0002] Generally, existing display devices include liquid crystal display devices and organic light emitting display devices. Wherein, the display device includes a gate driving circuit to provide a turn-on signal for the scanning lines of the display device, so as to control the scanning lines to perform display scanning so that the display device displays images. Existing gate driving circuits are composed of multi-stage shift registers, and the turn-on signals are transmitted to the scanning lines step by step through the shift registers. However, since the shift register consists of many components and occupies a large layout area, the frame of the existing display device is relatively wide, which does not conform to the current development trend of narrow frame of the displ...
