Fig. 2 is a schematic diagram of a conventional display panel structure in the prior art, in which a display area can display different pictures according to different data signals in a driving circuit, but a non-display area cannot emit light because no light-emitting layer material exists and no driving circuit exists.
In an embodiment of the invention, as shown in fig. 3, the display panel includes a substrate 1, an encapsulation layer 2, a light guide layer 3, and a cover plate 4. The package layer 2 is disposed on a side surface of the substrate 1, the light guide layer 3 is disposed on a side surface of the package layer 2 away from the substrate 1, the cover plate 4 is disposed on a side of the light guide layer 3 away from the substrate 1, as shown in the figure, the display panel is divided into a display area 101 and a non-display area 102, the non-display area is also generally called a border area (border), and the substrate 1, the package layer 2, the light guide layer 3 and the cover plate 4 cover the display area 101 and the non-display area 102.
