Abstract:
Provided is a display panel, including a through hole, an isolation area, and a display area. The isolation area is around the through hole. The isolation area is between the through hole and the display area. The isolation area includes at least two graphic marks for detecting the hole accuracy of the through hole. The at least two graphic marks are spaced apart from each other around the through holes. Graphic marks are arranged in an isolation area of a display panel. The isolation area is between a through hole and a display area. That is, the graphic marks are around the through hole.
