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

The embodiment of the invention provides a wiring structure and a stretchable display device. The wiring structure comprises a substrate, at least one bent guide wire located on the substrate and a positioning pin part located on the substrate, wherein the guide wires stretch to pass the positioning pin part to play a positioning role to movement of the guide wires. When the substrate is stretchedor compressed, the positioning pin part plays the positioning role to movement of the guide wires and the positioning pin part limits or guides the moving paths of the guide wires along at least onedirection. By arranging the bent guide wires and positioning pin part, the matching degrees of the guide wires stretched along with the substrate are improved and the ability that the guide wires recover the original shapes 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...
