Gate drive circuit unit and display panel thereof

Abstract

The invention provides a gate drive circuit unit and a display panel thereof. The gate drive circuit unit comprises a scanning input line, a first scanning control line, a second scanning control line, a first transistor, a second transistor, a third transistor and a fourth transistor. The scanning input line is connected with the source electrode of the first transistor and the source electrode of the third transistor. The first scanning control line is connected with the grid electrode of the first transistor, the drain electrode of the second transistor and the grid electrode of the fourth transistor. The second scanning control line is connected with the grid electrode of the second transistor, the grid electrode of the third transistor and the drain electrode of the fourth transistor. The drain electrode of the first transistor and the source electrode of the second transistor are both connected with the first scanning line in two adjacent scanning lines, and the drain electrode of the third transistor and the source electrode of the fourth transistor are both connected with the second scanning line in the two adjacent scanning lines. Due to the fact that each gate drive circuit unit can control two or more scanning lines, a narrow frame of the display panel can be achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a gate drive circuit of a display panel and a display panel with the gate drive circuit. Background technique [0002] At present, Liquid Crystal Display (LCD) has many advantages such as thinness, energy saving, and no radiation, and is widely used in products such as notebook computers, desktop computers, video recorders, smart TVs, mobile terminals, and personal digital processors. superior. Taking liquid crystal display devices applied to mobile phones as an example, under the premise of a certain size of mobile phones, users generally hope that the screen can be as large as possible, so how to realize the narrow frame of the display device has become the direction of extensive research and the goal pursued by the industry. [0003] Taking a thin film transistor (Thin Film Transistor, TFT) liquid crystal display device as an example, it includes a liquid crystal display pan...

Problems solved by technology

However, the reliability of the GIA circuit is poor, and the circuit is prone to abnormality under long-term work; moreover, the stability of the GIA circuit is poor, because it is integrated on the display panel, so if a certain circuit element is abnormal, it will cause the entire GIA circuit to be damaged. can not work
