Embodiment Construction

[0028] The technical solutions of the present invention will be further described below according to specific embodiments. The protection scope of the present invention is not limited to the following examples, which are listed for illustrative purposes only and do not limit the present invention in any way.

[0029] Now refer to image 3 , to illustrate a folding-resistant metal wire according to an embodiment of the present invention.

[0030] Such as image 3 As shown, the folding-resistant metal wire is deposited on the substrate, including stacked at least two metal stacks, that is, metal stack 1, metal stack 2, and metal stack 3, and so on. Metal stack 1 , metal stack 2 and metal stack 3 each include a first metal layer A and a second metal layer B of a material different from that of the first metal layer A. The metal stacks 1 , 2 , and 3 have the same structure, that is, the metal layers contained in them have the same composition, the same stacking sequence, and th...

Abstract

The invention provides a flexible display device and a folding-resistant metal wire. The folding-resistant metal wire comprises at least two metal stacked layers which are stacked. The metal stacked layers respectively comprise a first metal layer and a second metal layer, wherein the first metal layers and the second metal layers are made of different types of material, and material of the first metal layers and the second metal layers are selected from Al, Cu, Mo, Ti and Ag. According to the flexible display device and the folding-resistant metal wire, by regulating the thickness and the composition of all the metal layers, the resistivity of the metal wire is lowered, strength and toughness of the metal wire are enhanced, influences caused by membrane stress are eliminated, the metal wire can be more easily resistant to bending, stability of the display device is improved, and meanwhile the number of devices input to a production line can not be increased.

Description

technical field [0001] The invention relates to a display device, in particular to a flexible display device and a folding-resistant metal wire. Background technique [0002] Organic Light Emitting Diode (OLED) is a technology that utilizes reversible discoloration produced by organic semiconductor materials driven by electric current to realize display. OLED has ultra-light, ultra-thin, high brightness, large viewing angle, low voltage, low power consumption, fast response, high definition, shock resistance, bendable, low cost, simple process, less raw materials, high luminous efficiency and wide temperature range And other advantages, it is considered to be the most promising new generation display technology. [0003] At present, active matrix organic light emitting diode (AMOLED) flexible devices not only have the function of flat panel display devices, but also can be freely processed under any conditions due to their free curling and bending properties; When it is li...
