Problems solved by technology

[0003] A flexible display device usually includes a flexible substrate and a display device formed on the flexible substrate. The inventors of the present invention have found in long-term research and development that in the current prior art, the flexible substrate generally includes a substrate layer, and the substrate layer still uses the same Similar to the structure in traditional rigid display devices, the entire substrate layer is a full-surface type. This setting will cause a large bending stress that cannot be released during the subsequent bending process, which may cause the flexible substrate to break and shorten the service life.

Abstract

The invention discloses an OLED flexible substrate. The flexible substrate comprises a substrate layer, wherein the substrate layer comprises a first organic layer and an inorganic layer which are successively superimposed; and the first organic layer is a whole-surface film layer, and the inorganic layer is a patterned structure. By adopting the OLED flexible substrate, the OLED display panel andthe production method, the bendability of the flexible substrate can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED flexible substrate, an OLED display panel and a manufacturing method. Background technique [0002] Organic Light-Emitting Diode (OLED) display technology has increasingly become the mainstream display technology in the market because of its advantages such as self-illumination, wide viewing angle, high contrast ratio, low power consumption, and extremely high response speed. OLED display devices can be divided into rigid display devices and flexible display devices. Among them, flexible display devices have the advantages of being bendable, good impact resistance, strong shock resistance, light weight, small size and easy to carry. widespread attention of the people. [0003] A flexible display device usually includes a flexible substrate and a display device formed on the flexible substrate. The inventors of the present invention have found in long-term research and d...
