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.
Claims19
A display panel, comprising a through hole, an isolation area and a display area, wherein the isolation area is around the through hole and is between the through hole and the display area, and wherein the isolation area comprises at least two graphic marks, and the at least two graphic marks are spaced apart from each other around the through hole,
- wherein the isolation area is provided with at least one circle of isolation columns, each circle of isolation columns is arranged around the through hole, and the graphic marks are between the through hole and one circle of isolation columns proximate to the through hole.
A method for detecting hole accuracy of a display panel, comprising:
- taking a picture of the display panel with an optical detector, wherein the display panel comprises 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 comprises at least two graphic marks for detecting hole accuracy of the through hole, the at least two graphic marks are spaced apart from each other around the through hole, and the picture taken by the optical detector comprises the graphic marks and the through hole;
- determining minimum distances between an edge of the through hole and each of the graphic marks on the picture;
- and
- determining the hole accuracy according to the minimum distances between the edge of the through hole and each of the graphic marks,
- wherein the isolation area is provided with at least one circle of isolation columns, each circle of isolation columns is arranged around the through hole, and the graphic marks are between the through hole and one circle of isolation columns proximate to the through hole.
A display device, comprising a display panel, wherein the display panel comprises a through hole, an isolation area and a display area, wherein the isolation area is around the through hole and is between the through hole and the display area, and wherein the isolation area comprises at least two graphic marks for detecting accuracy of the through hole, and the at least two graphic marks are spaced apart from each other around the through hole,
- wherein the isolation area is provided with at least one circle of isolation columns, each circle of isolation columns is arranged around the through hole, and the graphic marks are between the through hole and one circle of isolation columns proximate to the through hole.
