AI Technical Summary
Technical Problem
The electrical signal in the display area is transmitted to the vicinity of the opening area through the isolation column, resulting in electrochemical corrosion near the opening area and causing packaging failure.
Method used
A first column made of insulating material is provided with isolation grooves surrounding the opening area on both sides of it to form an annular isolation structure to block the transmission of electrical signals.
Benefits of technology
It effectively blocks the electrical signal transmitted from the display area to the vicinity of the opening area, avoids electrochemical corrosion, and ensures the stability of the packaging.

Abstract
Provided in the embodiments of the present disclosure are a display panel and a manufacturing method therefor, and a display device, which belong to the technical field of displays. The display panel comprises a base substrate having a hole area and a display area, the display area surrounding the hole area. A plurality of isolation columns are located on a first surface of the base substrate, and the plurality of isolation columns are annular and surround the hole area. Each isolation column comprises a first column body made of an insulating material, and isolation grooves surrounding the hole area are respectively provided on two sides of the first column body. The embodiments of the present disclosure can improve the defect of packaging failure caused by electrochemical corrosion in the vicinity of the hole area due to the fact that electric signals in the display area are transmitted to the vicinity of the hole area through the isolation columns.
