Abstract

The invention discloses a manufacturing method of a flexible display device and the flexible display device. The manufacturing method comprises the following steps of S1, providing a flexible displaypanel, wherein the flexible display panel comprises a bending area and a metal wiring layer which is located in the bending area; S2, carrying out laser illumination on the metal wiring layer to ensure that the illuminated surface of the metal wiring layer is softened, and bending the flexible display panel at the bending area. According to the manufacturing method, the step of carrying out laserillumination on the metal wiring layer in the bending area of the flexible display panel is added on the basis of the original bending process, so that the illuminated surface of the metal wiring layer is softened, the plastic deformation performance is improved, and the circuits of the metal wiring layer of flexible display panel are not easy to crack or break in the bending process, thereby enhancing the bending strength of the metal wiring layer; and compared with the prior art, the flexible display panel is capable of bearing bending with larger curvature, so that the bending radius of thebending of the flexible display panel is decreased and the overall thickness of the flexible display panel after the bending is reduced.

Description

technical field [0001] The present application relates to the technical field related to flexible display devices, in particular to a method for manufacturing a flexible display device and a flexible display device. Background technique [0002] With the continuous development of electronic technology and the continuous improvement of the technological level, the full screen has become a hot trend at present; in order to expand the display screen of the smart phone, the overall size can be adjusted by bending at the Pad. Obviously, when the two ends of an object are grasped and bent, it will be divided into two parts of elongation and contraction centered on a certain position from the cross-section, and the elongation or The amount of shrinkage is proportional to the vertical distance from this position; from the section, if this part is extended along the long side of the slender object, it will become a right-angled quadrilateral surface, which is called the neutral surfa...
