Embodiment Construction

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0036] see Figure 3 to Figure 4 , the present embodiment provides a support layer 20, which is divided into three regions along the bending direction, wherein, the middle region of the support layer 20 is subjected to relatively large and relatively concentrated force during the bending process, which is very easy to Uneven stress occurs, uncoordinated deformation occurs, and even fracture occurs in severe cases. Therefore, the structural design of the support layer 20 should f...

Abstract

The present invention discloses a supporting layer and a flexible display panel, the holes and the openings are periodically formed in the supporting layer, and the first strip-shaped hollowed-out parts in the openings penetrate through the edge and / or the side face of the supporting layer, so that the ductility of module stacking can be improved on the whole, the adaptability and coordination between the supporting layer and the film layers of the module stack are guaranteed, the bending performance of the OLED module is improved, the debonding and breaking risks between the film layers are reduced, and the bending service life of the module stack is prolonged.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of flexible display technology, and in particular to a support layer and a flexible display panel. Background technique [0002] In recent years, organic light-emitting diode (OLED, Organic Light Emitted Diode) display technology has become increasingly mature. OLED modules are stacked on the basis of LED (Light Emitted Diode, light-emitting diode) technology, and their thickness has been significantly reduced, which makes flexible It shows that commercialization is possible. [0003] In recent years, various terminal manufacturers have successively launched flexible folding and roll-up display electronic products, but the relatively high prices lead to relatively low popularity of the products. The low production yield of flexible displays is the direct cause of this phenomenon. Among them, at the current stage, during the production process of flexible di...
