1. A display panel, comprising:
a first display area and a second display area adjacent to the first display area,
wherein each of the first display area and the second display area is provided with a plurality of subpixel driving thin-film transistors (TFTs) and a plurality of light-emitting subpixels, the subpixel driving TFTs in the first display area have a distribution density equal to a distribution density of the subpixel driving TFTs in the second display area, and a distribution density of the light-emitting subpixels in the first display area is greater than a distribution density of the light-emitting subpixels in the second display area; and
wherein the light-emitting sub-pixels are also arranged on a periphery of the second display area, some of the subpixel driving TFTs in the second display area are connected to the light-emitting subpixels in the second display area, and the other subpixel driving TFTs in the second display area are connected to the light-emitting subpixels on the periphery of the second display area through a plurality of metal lines.
