Abstract

The invention discloses a flexible display device and a preparation method thereof. The method comprises that an inorganic sacrificial layer, a flexible substrate and a display screen are prepared ona rigid substrate successively, and a bonding force between the flexible substrate and the inorganic sacrificial layer is lower than that between the inorganic sacrificial layer and the rigid substrate; laser is used to cut the flexible substrate, the edge of the flexible substrate after cutting is separated from the inorganic sacrificial layer due to contraction caused by laser burning, and a laser cutting position is between the edge of the display screen and the edge of the flexible substrate; and the flexible substrate is peeled from the rigid substrate along the contracted position of theedge of the flexible substrate via a mechanical outside force. Via the method, the whole flexible substrate is avoided from influence of high temperature caused by laser, the display screen is not damaged, and the service life of the flexible display device is not influenced.

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. Such ...
