Embodiment Construction

[0021] It can be seen from the background art that the performance of the stretchable display device in the prior art needs to be improved.

[0022] The analysis found that the stretchable display device includes a screen body AA (Active Area) area and a wire area surrounding the screen body AA area, the wire area has four wires, wherein the three wires are electrically connected to the screen body AA area and They are all straight lines, and the wires on the other side are used to bind FPC or IC. When stretching the AA area of ​​the screen, the straight wires cannot be stretched and matched accordingly. If the AA area of ​​the screen is stretched forcibly or the stretched length of the AA area of ​​the screen is longer, the wires in the wire area will be damaged, resulting in an open circuit The problem is that the wires in the wire area cannot match the stretching degree of the AA area of ​​the screen when stretching, which limits the stretching distance of the stretchable d...

Abstract

An embodiment of the present invention provides a wiring structure and a stretchable display device, including: a substrate; at least one bent wire on the substrate; a positioning pin part on the substrate, and the wire extends through the A positioning pin part, the positioning pin part plays a positioning role for the movement of the wire, and when the substrate is stretched or compressed, the positioning pin part plays a positioning role for the movement of the wire, and the positioning pin part plays a positioning role for the movement of the wire. The path of travel of the wire is constrained or directed in at least one direction. In the present invention, by arranging the bent wires and positioning pin components, the matching degree of the wires being stretched following the substrate is improved, and the ability of the wires to return to their original shape when the substrate is compressed is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a wiring structure and a stretchable display device. Background technique [0002] OLED (Organic Light-Emitting Diode) is called an organic light-emitting diode. OLED display technology has many advantages such as full solid state, active light emission, high contrast, ultra-thin, low power consumption, fast effect speed, wide working range, easy realization of flexible display and 3D display, etc., making it widely used in many display devices at present. , for example on televisions and mobile devices. [0003] Flexible OLED refers to a flexible organic light emitting diode, which is manufactured based on a flexible substrate and operates on the flexible substrate. Compared with traditional rigid OLEDs, flexible OLEDs are more flexible, lighter and thinner, making foldable and rollable display technologies possible. With the in-depth research on fl...
