Abstract

The invention discloses a preparation method of a flexible display panel, a flexible display panel and a display device, which are used for reducing the difficulty of bending a bending area of ​​the flexible display panel. The preparation method of the flexible display panel includes: attaching a back film on the back of the display substrate, wherein the display substrate is divided into a display area and a non-display area, and the non-display area includes a curved panel adjacent to the display area. A folding area, and a binding area adjacent to the bending area, the back film has a continuous pattern covering the display area and extending to the non-display area, and the back film has a hollow area in the non-display area , the orthographic projection of the hollow area on the display substrate at least covers the area between the binding area and the display area in the bending area; at least remove the back film on the front of the display substrate Projecting the part covering the bending area; bending the display substrate toward the back along the bending area to form the flexible display panel.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal display, in particular to a method for preparing a flexible display panel, a flexible display panel and a display device. Background technique

[0002] In a flexible organic light-emitting diode (Organic Light-Emitting Diode, OLED) display, POL (polarizer), Panel (flexible panel), Back Film (back film, adhered to the Panel by OCA optical glue), etc. are bonded together , in order to achieve a narrow frame, the Panel can be bent at its Pad end (the end connected to the external circuit).

[0003] The current manufacturing process of flexible display devices, taking flexible OLED as an example, generally includes the following steps: making OLED devices on a flexible substrate, then performing a thin-film packaging process on the OLED devices, and attaching a front plate protective film. In order to facilitate bending, The back film located in the bending area is peeled off, and a protective...
