Abstract

The invention discloses a grid drive circuit of an array baseplate. The circuit comprises a first capacitor, a first thin film transistor T1, a second thin film transistor T2, and a charging-discharging access, wherein one end of the first capacitor is taken as a first upward pull node, and the other end of the first capacitor is taken as a second upward pull node; a grid of the T1 is connected to the first upward pull node, and a source electrode of the T1 is connected to the second upward pull node; a grid of the T2 is connected to the second upward pull node, a drain electrode of the T2 is connected to a direct current high-level signal end, and a source electrode of the T2 is taken as an output end of the circuit; and after the charging-discharging access charges the first capacitor C1, the C1 and T1 will conduct voltage bootstrap of the first upward pull node, thus clock signals provided by CK can be conducted to the second upward pull node, and T2 makes a high level provided by VGH control output of the grid drive circuit of the array baseplate, so that the circuit drive capacity is obviously enhanced, and the circuit is characterized by low output noise and high stability. The invention also discloses a touch control display device and a piece of touch control electronic equipment.

Description

technical field [0001] The present invention relates to the field of display control technology, in particular to an array substrate gate drive circuit, a touch display device and a touch electronic device. Background technique [0002] Stability, low power consumption and low cost are issues that the entire LCD panel industry pays more attention to. In recent years, as the size of LCD panels has become larger, the degree of integration has become higher, and the circuit structure has become more and more complex, reducing power consumption and increasing system stability have become more important. Therefore, low power consumption and stability have become the focus of attention in the field of GOA (Gate Driver on Array) technology in recent years, and the performance of GOA directly affects the reliability and stability of the entire display system. , affecting the display effect of the display panel. Contents of the invention [0003] The present invention aims to sol...
