A flexible substrate, a display device and a method for bonding an electronic device onto a flexible substrate are disclosed. The flexible substrate includes a base substrate, the base substrate includes a bonding portion for bonding an electronic device and an auxiliary bonding portion integrally formed with the bonding portion, the auxiliary bonding portion and the bonding portion are disposed back to back, and the bonding portion completely falls into a region where the auxiliary bonding portion is provided in an orthographic projection direction. With an auxiliary bonding portion being disposed beside the bonding portion for bonding the electronic devices such as ICs and FPCs, when bonding the electronic device onto the bonding portion, the auxiliary bonding portion can enhance the strength of the bonding portion and improve the bonding alignment precision and contact property of the electronic device, which further improves the non-defect ratio of the flexible display device and has a lower cost.

An electrostatic wall sticker, use thereof, process for manufacturing the same, and method for storing and transporting the same are disclosed. The electrostatic wall sticker comprises the sticker body comprising a using layer made of plastic film which comprises a first side and a second side, and an adhesive layer made of plastic film which comprises a first side and a second side. It can effectively replace traditional wall stickers. This invention has the advantages of securely mounting on any dry surface without the need of adhesive agents, leaving no mark upon removal and being highly environmentally friendly. Also, this electrostatic wall sticker possesses the properties of face-to-face and rolling storage of static electricity, which makes transportation convenient.

A panel structure having a low-density core that can withstanding loads normal to a first primary surface, and a first facing of high-density sheet material that can extend along the first primary surface. The high-density sheet material can be laminated on the core such that the laminated core and facing cooperatively resist bending loads and loads along the primary surface. The first facing can extend from the first primary surface on a side of the core along a secondary surface, which can be non-parallel to the first primary surface. The first facing can bend along a score line between the first primary surface and the secondary surface.
