Abstract
The invention belongs to the technical field of display, and particularly relates to a composite substrate and a flexible display screen. The composite substrate provided by the invention comprises a structural unit, and the structural unit comprises a flexible substrate and a metal layer arranged on the flexible substrate; a first concave-convex structure is arranged on the flexible substrate, and the first concave-convex structure is arranged on the surface, connected with the metal layer, of the flexible substrate. The composite substrate has excellent bending performance and good sealing performance, and moisture and oxygen in the external environment can be effectively blocked. When the composite substrate is applied to preparation of the flexible display screen, each functional thin layer in the flexible display screen can be well protected, the service life of the flexible display screen is prolonged, and commercial application of the flexible display screen is promoted.
Description
technical field [0001] The invention belongs to the field of display technology, in particular to a composite substrate and a flexible display screen. Background technique [0002] Flexible display has the advantages of impact resistance, light weight, and easy portability. It has functions and user experience advantages that cannot be realized by traditional displays, and has become one of the future development directions of the display industry. [0003] At present, flexible display screens often use flexible substrates, and the materials of flexible substrates are mainly organic polymers, which have poor water and oxygen barrier properties. Because organic light-emitting materials and quantum dot light-emitting materials are very sensitive to moisture and oxygen, the lifespan of flexible displays based on organic light-emitting diodes (OLEDs) is still not as good as that of traditional liquid crystal displays. Quantum-dot light-emitting diodes (QLEDs) Flexible displays ...
