Abstract

The invention provides a display panel and a display device. The display panel has a display region and a non-display region located on one side of the display region, wherein a binding region is arranged in the non-display region. The display panel comprises an organic layer arranged on a substrate, an inorganic layer and a bonding layer located between the organic layer and the inorganic layer in the binding region, wherein the surface roughness of the bonding layer is greater than the surface roughness of the organic layer and the inorganic layer. According to the display panel and the display device, the bonding layer is arranged between the organic layer and the inorganic layer, and the plurality of concave-convex structures are arranged on the surface, in contact with the bonding layer, of the organic layer and / or the inorganic layer, so that the interface bonding force is enhanced, and the problem that in the prior art, a film layer is easy to strip when an FPC is bound to a display panel 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] Organic light-emitting diodes (Organic light-emitting diodes, OLED) display panel has the advantages of self-illumination, high contrast, thin thickness, wide viewing angle and fast response speed. Admired. Usually, a binding area is provided on the display panel, and an external flexible printed circuit (FPC, FPC) is bound to the binding pads of the binding area to provide an external driving power signal for the display panel. The bonding pads are usually formed by patterning the metal conductive layer in the touch layer, and are overlapped with the metal lines in the array substrate to realize signal conduction between the FPC and the display panel. [0003] The touch layer can use DOT (Direct on-cell touch, the touch screen is directly embedded on the display) technology to directly make a metal co...
