Problems solved by technology
However, in the manufacturing process of the array substrate, the back of the substrate will be rubbed against the conveying mechanism during the transmission process and will be charged with static electricity. This static electricity will induce electrification of the lines on the front of the substrate. Therefore, the static electricity generated by the substrate during the transfer process is likely to cause damage to the electronic devices in the peripheral circuit area.

The embodiment of the invention discloses an array substrate, a display panel and a display device. The array substrate comprises a display area and a peripheral circuit area surrounding the display area, the peripheral circuit area is provided with a gate drive circuit, the gate drive circuit comprises a plurality of cascaded shift registers, and the shift register comprises at least one thin film transistor. The array substrate further comprises a substrate; a first metal layer which is located at one side of the substrate and comprises a grid electrode of the thin film transistor; and at least one shielding ring which is positioned between the substrate and the first metal layer, and the vertical projection of the gate drive circuit on the substrate is located in a region surrounded bythe vertical projection of the shielding ring on the substrate. The array substrate provided by the embodiment of the invention is favorable for improving the anti-static damage capacity of the peripheral circuit area in the production process of the display panel.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to an array substrate, a display panel, and a display device. Background technique [0002] In order to better realize human-computer interaction, various smart terminals such as mobile phones, tablet computers, smart wearable devices, and information inquiry machines in the lobby of public places are equipped with display panels, and display panels have been widely used. [0003] Among them, the array substrate is an important part of the display panel. However, in the manufacturing process of the array substrate, the back of the substrate will be rubbed against the conveying mechanism during the transmission process and will be charged with static electricity. This static electricity will induce electrification of the lines on the front of the substrate. Therefore, the static electricity generated during the transfer of the substrate may easily cause d...
