Abstract

The invention discloses a flexible display panel and a display device. The flexible display panel comprises a PAD area, and a heat conduction anti-wrinkle layer is fixedly stacked on one side of the PAD area. According to the scheme, the heat-conducting anti-wrinkle layer is arranged in the PAD area, so that the temperature of the pressure head during crimping can be diffused, the thermal deformation of the pressure head can be ignored, and the thermal deformation of the PAD area fixed with the heat-conducting anti-wrinkle layer correspondingly can also be ignored due to the fact that the thermal deformation of the heat-conducting anti-wrinkle layer can be ignored; therefore, the problem that the PAD area is wrinkled due to crimping is solved, and the binding precision of subsequent procedures is guaranteed.

Description

technical field [0001] The present invention generally relates to the field of display technology, and in particular to a flexible display panel and a display device. Background technique [0002] A flexible display panel usually includes a display area (AA area) and a PAD area, wherein the PAD area is a crimping area, which is used to crimp the signal lines of the AA area with the external driver circuit board, the leads and pins of the driver IC. Area. During crimping, the temperature of the indenter is generally higher than 60°C, and the back film material of the flexible display panel is generally PET (PolyethyleneTerephthalate; polyethylene terephthalate) material, and the substrate is PI (Polyimide; polyimide) Amine) materials, PET materials, and PI materials are inconsistent in thermal deformation, which leads to wrinkles in the PAD area and affects the bonding (Bonding) accuracy of subsequent processes. Contents of the invention [0003] The present application e...
