Patent number: 11594182Abstract: The present invention provides a gate driver on array (GOA) circuit, a display panel, and a threshold voltage compensating method for a thin film transistor (TFT). The GOA circuit only includes five TFTs and achieves a super narrow bezel of a display panel, and uses a dual-gate electrode structure as the first thin film transistor (T1). Therefore, a threshold voltage (Vth) in the GOA circuit is controlled by a top gate (the top gate connected to a node in the GOA circuit) and a bottom gate (adjustable voltage source (VLS)). Specifically, when the Vth of the TFT negatively shifts overall, the bottom gate voltage can be adjusted negatively. When the Vth of the TFT positively shifts, the bottom gate voltage can be adjusted negatively to stabilize the GOA circuit, increase a lifespan thereof, reduce leakage of a first node (Q) such that the GOA circuit can output ultra-wide pulse signals.Type: GrantFiled: December 26, 2019Date of Patent: February 28, 2023Assignee: Shenzhen China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Yan Xue, Baixiang Han
