Embodiment Construction

[0054] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0055] At present, in the field of display technology, a flexible display panel can be formed with a narrow frame or no frame by setting a bending area on the flexible display panel. A display panel in the prior art is to lay metal wires on the inorganic layer area of ​​the display panel. The metal wires can be directly laid on the inorganic layer area, or can be bent slightly on the inorganic l...

Abstract

The invention discloses a flexible display panel and a manufacturing method thereof, belonging to the technical field of display. The flexible display panel includes a base substrate; the base substrate has an inorganic layer structure, the inorganic layer structure includes a plurality of inorganic layers, the base substrate has a bending area, and the inorganic layer structure has grooves in the bending area; an inorganic layer is provided The base substrate of the structure is provided with a bending bearing structure, the bending bearing structure is located in the groove, and the side of the bending bearing structure away from the base substrate has a plurality of alternately arranged convex structures and groove structures, and is provided with There is at least one trace on the base substrate of the bent carrying structure. The orthographic projection of at least one trace on the substrate is bent, and the trace is bonded to the raised structure and the groove structure to form a bent structure with high bending performance, which solves the problems of the traces in the prior art. The bending performance is low, and the problem that the display panel is easy to break during the bending process achieves the effect of improving the performance of the bending area.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a manufacturing method thereof. Background technique [0002] A flexible display panel is a device that is flexible and has a display function. Through its flexibility, it can meet the application requirements of various scenarios. [0003] In the related art, there is a display panel, which has a base substrate and a multi-layer inorganic layer formed on the base substrate, and traces are arranged on the multi-layer inorganic layer. The display panel has a bending area, and the part of the wiring located in the bending area has a certain bending on the surface of the inorganic layer, so as to avoid the breaking of the wiring during the bending process of the display panel. [0004] The bending performance of the wires in the above display panel is relatively low, and it is still easy to break during the bending process of the display panel. Cont...
