Abstract

The invention discloses an array substrate and a display panel, and relates to the technical field of display, the array substrate comprises a substrate and a transistor located on one side of the substrate, the transistor comprises an active layer, an insulating layer and a gate metal layer, the active layer is located on one side of the substrate and comprises a main channel region and an edge channel region, the insulating layer covers the active layer, and the gate metal layer covers the main channel region. In the gate metal layer, in the direction perpendicular to the plane where the substrate is located, the region overlapped with the main channel region is a first region of the gate, and the region overlapped with the edge channel region is a second region of the gate. A channel, between the source electrode and the drain electrode, of carriers in the edge channel region is blocked to different degrees, or the distance between the second region of the grid electrode and the edge channel region is increased, the second region of the grid electrode cannot be opened in advance, the double-peak phenomenon is improved, and the performance reliability is improved.

Description

Technical field [0001] The present invention relates to the field of display, and more particularly to an array substrate and a display panel. Background technique [0002] Currently, display technology penetrates all aspects of people's daily lives, and more and more materials and techniques are used for display. The display panel is an important component of the display device for implementing the display function of the display device. Today, the mainstream display mainly has a liquid crystal display panel, an organic light-emittingdiode, OLED, a micro LED, and a mini Luminested display panel (MINI LED). [0003] The liquid crystal display panel has the advantages of light, power consumption, low radiation, etc. The generated light transmits the display panel, by adjusting the size of the electric field, the degree of deflection of the liquid crystal molecules can be different, while the liquid crystal molecules are deflected, the light transmittance of the display panel is di...
