The present application discloses a flexible display panel, a preparation method and device for the flexible display panel. The flexible display panel includes a bending area and a non-bending area adjacent to the bending area. The flexible display panel includes a support layer, a buffer layer and a buffer layer arranged in sequence. layer, backlight module layer and display layer, the support layer includes a first support portion corresponding to the bending area and a second support portion corresponding to the non-bending area, the first support portion is provided with a plurality of holes, and the buffer layer includes The first buffer part and the second buffer part adjacent to the first buffer part, along the first direction, the thickness of the first buffer part is smaller than the thickness of the second buffer part, and the orthographic projection of the first buffer part covers the front of the first support part. projection. In the present application, a buffer layer is arranged between the display layer and the support layer, so that the support layer is not in contact with the display layer, so as to prevent the shape of the hole from being transferred to the display layer; at the same time, the first buffer portion is arranged to provide a deformation space for the first support portion. , to avoid peeling or cracking of the flexible display panel during the bending process.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a flexible display panel, and a method and device for preparing the flexible display panel. Background technique [0002] The flexible display screen needs to have a certain degree of stiffness while having a bendable performance. Therefore, it is necessary to stick a support layer on the back of the display module for support, and the support layer has a higher modulus than other film materials. When bending The stress is large, and multiple bending is prone to cracks, resulting in product failure. [0003] In order to improve the bending performance of the support layer and reduce the bending stress, a perforation design will be carried out in the bending area; however, since the materials on the support layer are all film materials, the material is soft, and the holes on the support layer will be removed during lamination. The hole is transferred to the displa...
