AI Technical Summary
Technical Problem
In the ultra-narrow bezel design of OLED displays, the wiring layout is prone to defects, especially during T Aging, where burn-in defects caused by adjacent high and low voltage signal lines are difficult to resolve.
Method used
At least one groove is provided between two adjacent signal lines to form a barrier, reduce the risk of short circuits, and improve the problem of burn-in caused by the adjacent positions of high and low voltage signal lines.
Benefits of technology
The recessed design reduces the risk of signal line short circuits, improves the burn-in problem in narrow bezel designs, and is simple and low-cost.

Abstract
This disclosure provides an OLED display substrate, a method for manufacturing the same, and a display device. The display substrate includes: a substrate having a display area and a border area surrounding the display area; the border area includes a bonding area for connecting a driver chip; a driving unit disposed in the border area for driving multiple pixels in the display area for display; and multiple signal lines disposed in the border area, wherein the input terminal of the driving unit and the output terminal of the driver chip are electrically connected through the multiple signal lines. At least two adjacent signal lines have at least one groove between them, and the voltage difference between two adjacent signal lines is greater than a predetermined value.
