Abstract

The invention discloses a flexible display device. The device comprises a flexible substrate provided with a non-display area, an organic buffering layer arranged on the non-display area of the flexible substrate, and an organic protective layer arranged on at least one metal wire and provided with a first organic protective layer section and a second organic protective layer section, wherein themetal wires are arranged on the organic buffering layer; the first organic protective layer section is arranged on one folding center line portion of the non-display area, and the first elastic modulus of the first organic protective layer section is greater than the second elastic modulus of the second organic protective layer section. The elasticity of the portion, at the folding center line, ofthe organic buffering layer is greater than that of the materials on the two sides of the folding center line to buffer the stress so as to reduce the risk that the fracturing of a membrane layer iscaused and spreads to a metal conducting layer, so that the short circuit phenomenon is caused.

Description

technical field [0001] The present invention relates to a flexible display device, in particular to a bendable flexible display device. Background technique [0002] Currently, organic light-emitting diodes (eg, active-matrix organic light-emitting diodes (AMOLED)) have self-rotating optical activity, so no additional backlight module is required. Furthermore, it has the advantages of fast response speed, high contrast ratio, and wide application range of temperature. Compared with other display technologies, the biggest feature of organic light-emitting diodes is that they can realize flexible displays. Flexible displays have high requirements on component manufacturing process and materials. As full-screen mobile phones are increasingly favored by consumers, OLED flexible display technology can configure the non-display part of the component to be bendable, making the display part significantly larger. However, bending has higher requirements for manufacturing, and long...
