Abstract
The present application discloses a method for preparing a flexible display device and the flexible display device. The method includes: sequentially preparing an inorganic sacrificial layer, a flexible substrate, and a display body on a rigid substrate, and the flexible substrate and the inorganic sacrificial The bonding force between the layers is smaller than the bonding force between the inorganic sacrificial layer and the rigid substrate; the flexible substrate is cut by laser, so that the edge of the cut flexible substrate shrinks due to laser ablation and the inorganic sacrificial layer Layer separation, the cutting position of the laser is between the edge of the display body and the edge of the flexible substrate; the flexible substrate is peeled off from the rigid substrate along the contraction of the edge of the flexible substrate by mechanical external force. In this method, the whole flexible substrate will not be affected by the high temperature generated by the laser, so the display body will not be damaged, and the service life of the flexible display device will not be affected.
Description
technical field [0001] The embodiments of the present application relate to the technical field of manufacturing flexible display devices, and in particular, to a method for manufacturing a flexible display device and the flexible display device. Background technique [0002] Flexible display devices are being used more and more widely due to their lightweight, bendable, foldable, and portable properties. The manufacturing process of the existing flexible display equipment is roughly as follows: first fix the flexible substrate on the rigid substrate, then perform the processes of fixing and packaging the display body on the flexible substrate, and after the packaging is completed, the flexible substrate is fixed The bottom is peeled off from the rigid substrate to obtain a flexible display device. [0003] At present, in the manufacturing process of flexible display devices, a common way to peel off the flexible substrate from the rigid substrate is: laser lift-off. like ...
