Title:
GOA CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/090875
Kind Code:
A1
Abstract:
A GOA circuit. The GOA circuit utilizes a high voltage of a high frequency clock signal (CK) to raise a voltage of a second node (W(n)) during transmission of a scanning signal (G(n+4)), such that the voltage of the second node (W(n)) is greater than a voltage of a stage transmission signal (ST(n-4)) at an n-4 stage GOA unit, thereby ensuring a pull up control module (100) remains switched off during transmission of the scanning signal (G(n+4)). The invention improves the stability of a GOA circuit and prevents failure thereof.
