Abstract

The present invention provides a flexible display panel and a method for preparing the flexible display panel, wherein the flexible display panel includes: sequentially stacking a first flexible substrate, a first carbonized layer, and a display structure layer, and the first carbonized layer The laser transmittance is smaller than the laser transmittance of the first flexible substrate. The laser transmittance of the first carbonized layer in the above-mentioned flexible display panel is smaller than that of the first flexible substrate, which can effectively prevent the incident from the surface of the first flexible substrate away from the display structure layer from entering the display structure. The laser in the display structure layer reduces the laser energy entering the display structure layer, reduces the laser transmittance, avoids the display structure layer being affected by the laser, and then reduces the impact of the laser on the electrical properties of the thin film transistor in the display structure layer, prolonging the Displays the lifetime of the device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a method for preparing the flexible display panel. Background technique [0002] With the development of display technology, flexible display devices have been applied more and more widely. Since the substrate of the flexible display panel is a flexible substrate, the production of the existing flexible display panel mainly uses the substrate as a carrier to carry the flexible substrate, and then forms a display device on the flexible substrate, and finally the flexible substrate and the carrier The substrate is separated to obtain a flexible display panel. [0003] In the flexible substrate manufacturing process, the peeling of the flexible substrate and the carrier substrate is one of the most important links in the entire manufacturing process. At present, the commonly used peeling method is to use a laser to carbonize the contact surface of the ...
