Abstract

The embodiment of the invention discloses a display device which comprises a display panel and a flexible circuit board. The display panel comprises a cutting edge and a plurality of first bonding pads, the flexible circuit board comprises a substrate, the substrate comprises a binding area and a non-binding area, the binding area is provided with a plurality of second bonding pads, the non-binding area is provided with an insulating layer, the second bonding pads are in binding connection with the first bonding pads on the display panel, the insulating layer is located between the substrate and the cutting edge, and the insulating layer is overlapped with the cutting edge. According to the display device provided by the embodiment of the invention, the insulating layer of the non-bindingarea is located between the substrate and the cutting edge, the insulating layer is overlapped with the cutting edge, and the plurality of second bonding pads of the binding area are isolated from thecutting edge through the insulating layer, so that after the plurality of second bonding pads arranged in the binding area are bound with the plurality of first bonding pads of the display panel, theprobelms that the area outside the binding area makes contact with metal chips on the cutting edge, a COF line is short-circuited and display performance is affected due to the fact that a display dark line is formed are avoided, and the display performance of the display device is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display device. Background technique [0002] As smart products and wearable devices gradually become hot spots, the demand for flexible display panels continues to expand. In the design of existing flexible products, there are GL (Gate line) lines near the cutting edge, and there are bonding pads on the flexible display panel inside the cutting edge, and the chip-containing flexible circuit board (Chip On Film, COF) is being bonded. Before the manufacturing process, laser shape cutting is required to cut off the excess part of the flexible display panel. The existing COF bonding process is to bond the pads (COF pads) on the flexible circuit board to the flexible display panel. The pads are connected by ACF (Anisotropic Conductive Film, Anisotropic Conductive Film) conductive adhesive to realize signal transmission. [0003] After the existing fl...
