Abstract

The invention provides a display panel, a preparation method thereof and a display device. The display panel is divided into a bending area and a non-bending area. The display panel comprises a substrate layer, a thin film transistor layer which is located on the substrate layer and corresponds to the non-bending area, an organic filling layer which is located on the substrate layer and corresponds to the bending area, a planarization layer which is located on the thin film transistor layer and the organic filling layer, and a pixel electrode which is located on the planarization layer, wherein the pixel electrode in the bending area is connected with a source electrode of the thin film transistor layer in the non-bending area through a metal wire, the organic filling layer comprises a plurality of second via holes, and the plurality of second via holes are filled with organic photoresists. The plurality of via holes are formed below the metal wires in the bending area and are filled with the organic photoresists, so that the risk of breakage of the metal wires can be reduced, and the stress of each film layer during bending is greatly relieved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a preparation method thereof and a display device. Background technique [0002] A rigid OLED display panel becomes a bendable flexible OLED display panel. The biggest challenge is the stress problem. Because the entire display screen is composed of multiple layers of materials, the material is squeezed during bending, which will easily break and affect the display. [0003] The prior art bendable OLED display panel uses the method of etching the inorganic film layer in the bending area and filling the organic photoresist to release the stress during bending. However, this structure has certain limitations, such as being unable to achieve High resolution, complex process, and difficult manufacturing process. In addition, because the entire thin film transistor is bent during bending, there is still a risk of wire breakage, and the electrical properties of the t...
