Problems solved by technology

[0004] In the above-mentioned production process, laser is usually used to peel off the back film located in the bending area, but in order to avoid damage to the circuit of the OLED display device, laser is usually used to peel off the part of the back film located in the bending area, which results in the The thickness of the back film in the folding area is still relatively thick, which is not conducive to bending
At the same time, the thermal influence of the laser and the generated Particle (dust particles) are likely to cause damage to the circuit

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...
