Transistor structure and operation method thereof

Abstract

The invention discloses a transistor structure and an operation method thereof, wherein the transistor structure includes a substrate, an intrinsic semiconductor layer, a gate, a first source / drain, asecond source / drain and a shielding metal layer. The intrinsic semiconductor layer is arranged on the substrate. The intrinsic semiconductor layer includes a channel part, a first transition part,a second transition part, a first contact part and a second contact part. The gate overlaps with the channel portion of the intrinsic semiconductor layer. The intrinsic semiconductor layer is locatedbetween the substrate and the gate. The first source / drain contacts the first contact of the intrinsic semiconductor layer. The second source / drain contacts the second contact part of the intrinsic semiconductor layer. The shielding metal layer is arranged between the substrate and the intrinsic semiconductor layer. The shielding metal layer includes a shielding pattern, a first shielding electrode and a second shielding electrode. The first mask electrode and the second mask electrode overlap the first transition part and the second transition part respectively. The mask pattern overlapsthe channel part.

Description

technical field [0001] The present invention relates to a transistor structure and method of operation thereof. Background technique [0002] Reducing the driving frequency of the liquid crystal display panel can achieve the effect of energy saving. However, when the liquid crystal display panel is operated at a low frequency, the brightness of the frame is likely to decrease due to the leakage of the pixel structure, and when the next frame is updated, the brightness will increase significantly, resulting in a flicker phenomenon.
