Thin-film field effect transistor, driving method thereof, array substrate, display device, and electronic product

Abstract

The disclosure provides a thin film field effect transistor, a driving method thereof, an array substrate, a display device and an electronic product. The thin film field effect transistor comprises a gate metal layer and a semiconductor layer, and further comprises a guide layer, wherein when an electric field is formed between the gate metal layer and the semiconductor layer, an electric field is also formed between the guide layer and the gate metal layer, the semiconductor layer accumulates electrons or holes to reinforce the electric field between the gate metal layer and the semiconductor layer by utilizing the electric field between the guide layer and the gate metal layer. Through the guide layer, it is able to affect the current characteristics of the thin film field effect transistor by improving its structure, thereby to reduce a threshold voltage and a leakage current.
