Abstract

An array gate drive circuit located in a display panel. The array gate drive circuit comprises a first thin-type transistor (T1), a second thin-type transistor (T2), a third thin-type transistor (T3), a fourth thin-type transistor (T4), a fifth thin-type transistor (T5), a sixth thin-type transistor (T6), a seventh thin-type transistor (T7), an eighth thin-type transistor (T8), a ninth thin-type transistor (T9), a first boot thin-type transistor (T10), a second boot thin-type transistor (T11), a boost capacitor (C_boost), a twelfth thin-type transistor (T12), a thirteenth thin-type transistor (T13), a fourteenth thin-type transistor (T14) and a fifteenth thin-type transistor (T15). The boost capacitor (C_boost) is connected between a drain electrode of the eighth thin-type transistor (T8) and a voltage dividing point (K). The voltage dividing point (K) is located between the first boost thin-type transistor (T10) and the second boost thin-type transistor (T11). The level of a gate output signal (S_Q) output by a gate electrode of the second thin-type transistor (T2) is pulled high via the first boost thin-type transistor (T10), the second boost thin-type transistor (T11) and the boost capacitor (C_boost).

Description

technical field [0001] The invention relates to an array gate drive circuit and a display panel, in particular to an array gate drive circuit and a display panel for amorphous silicon thin film transistors (thin film transistor, TFT). Background technique [0002] The Gate-driver On Array (Gate-driver On Array) technology has been widely used in the panel now, it can save the cost of the gate integrated circuit (IC), and can also reduce the width of the panel frame. Narrow frame design is very beneficial and is an important technology for future panel design. [0003] Generally, array gate drive circuits using amorphous silicon (a-Si) thin film transistors often need to design a boost capacitor, one end of which is connected to the gate output end, and the other end is connected to the corresponding gate line. When the array gate drive circuit outputs gate pulses, the boost capacitor can raise the potential of the gate output terminal to ensure normal output of the array g...
