Abstract

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises a plurality of welding pads, wherein each welding pad is electrically connected with a pin of a driving chip; and the levels of the signals received by at least two adjacent welding pads are different, and at least one protection welding pad is arranged between the two adjacent welding pads with different levels of the received signals. According to the embodiment of the invention, a possibility that the welding pads are corroded can be reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] With the development of display technologies, users have higher and higher requirements on display quality of display panels. In order to drive the light-emitting elements in the display panel to emit light, the driving chip is usually bound on the array substrate of the display panel by using metal pads, and the driving chip transmits driving signals to the light-emitting elements through the metal pads. However, the metal pads are easily corroded, and the corroded metal pads cannot transmit driving signals normally, which affects the display quality of the display panel. Contents of the invention [0003] Embodiments of the present application provide an array substrate, a display panel, and a display device, which can reduce the possibility of welding pads being corroded.
