Abstract

The invention provides a display panel and a display device. According to the display panel, a driving circuit of a driving circuit layer is divided into a first part, a second part and a connecting part, the first part is positioned at one side of a substrate, the second part is positioned at the other side of the substrate, and the projection area of the second part on the substrate is positioned in the projection area of the first part on the substrate, so that the second part is located in a display area, an external lead connection area which cannot be displayed is eliminated, a frame ofthe display panel is eliminated, and the technical problem that the external lead area of an existing LED display screen is larger, so that the frame is bigger, is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The existing LED (Light-Emitting Diode, light-emitting diode) display uses Mini-LED (mini light-emitting diode) or Micro-LED (miniature light-emitting diode) as the light-emitting layer, and the Mini-LED and Micro-LED are set on the driver backplane , so that the driving backplane drives the Mini-LED or Micro-LED to emit light to realize the display. There is a display area and an external lead connection area on the driving backplane, and there is a driving circuit in the display area and the external lead connection area, but due to the external lead connection area It cannot be displayed, so that there is a border on the LED display, which affects viewing. [0003] Therefore, the existing LED display screen has the technical problem that the external lead area is large, resulting in a large frame. ...
