Abstract

A single display panel and an electronic device are provided. The single display panel comprises an upper substrate; a lower substrate including a display area and a stepped area; and a frame adhesive disposed between the upper substrate and the to a substrate, and surrounding the display area, wherein there is no blank area around the display panel. The single display panel is obtained from an array substrate comprising OLED display panels to be separated from each other through a cutting, wherein the display panel includes a display area, at least two adjacent display panels are connected through the frame adhesive disposed at an edge frame surrounding the display area but not covering the display area, and there is no cutting headroom between at least one side of the at least two adjacent display panels.

Claims (51)

1. A single display panel, comprising:

an upper substrate;
