Problems solved by technology

In this way, the overall GOA unit circuit and cascaded GOA circuits contain more thin film transistors and capacitors, and the GOA circuits are usually designed to be arranged on the edge of the display array substrate, which is not conducive to the narrowing design of the display frame.
At the same time, the two circuit parts are independent of each other, and the problem of output misalignment is easy to occur.

Abstract

The invention discloses a GOA circuit unit, which comprises a scanning part and an inverter, wherein the inverter is connected to an output end of the scanning part; and a scanning signal, which is outputted from the scanning part, is processed by virtue of the inverter, so that an emitting signal is generated. By generating the emitting signal via the inverter, a circumstance of generating the emitting signal through the additional use of thin film transistors and capacitors can be avoided, so that the quantities of the thin film transistors and the capacitors can be reduced, and border narrowing design can be facilitated. The invention also provides a GOA circuit and a display panel using the GOA circuit unit and a driving method of the GOA circuit unit.

Description

technical field [0001] The present invention relates to a gate driver on array (Gate Driver On Array, GOA for short) circuit unit, a GOA circuit using the GOA circuit unit, and a display panel using the GOA circuit. Background technique [0002] In the field of display technology, an array substrate gate driver (Gate Driver On Array, GOA for short) circuit is often used to drive the pixel circuit instead of an external chip. The GOA circuit uses the array substrate manufacturing process of the display to manufacture the gate driver ICs (Gate Driver ICs) on the array substrate (also known as the Array substrate). At the same time, because the GOA circuit manufactures the gate driving circuit on the array substrate, the integration degree of the display device is also improved. [0003] Wherein, the GOA circuit is formed by cascading multiple GOA circuit units, and each GOA circuit unit drives at least one row of pixels on the display array substrate. The GOA circuit unit ca...
