Problems solved by technology
During the preparation or use of the flexible screen, it is usually bent, but there are multiple signal lines inside the flexible screen, usually made of metal, which is relatively brittle, and the bending action can easily lead to the bending of the signal lines stress concentration, cracks, or even breakage, which will adversely affect the production yield and service life of the flexible screen

The invention discloses a flexible screen body, and belongs to the technical field of display. The flexible screen body comprises an insulating layer and a plurality of signal lines, at least parts of the signal lines spirally extend in the length extension direction of the signal lines and form spiral spaces, the spirally extending signal lines are located on different planes, and the spiral spaces are at least filled with the insulating layer. It can be seen that at least part of the signal line is designed to be in the three-dimensional spiral shape and provided with the spiral space which is equivalent to a spring structure, when the flexible screen body is bent corresponding to the part of the signal line, the spiral signal line can correspondingly deform corresponding to tensile stress and extrusion stress generated by bending, and stress concentration at the bent position is reduced. In addition, the insulating layer at least filling the spiral space can be made of an organic material, so that the signal line is protected, and the stress at the bent part is further released. According to the flexible screen body, the probability that the signal lines crack and break can be reduced, and therefore the bending resistance of the flexible screen body is improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a flexible screen body. Background technique [0002] With the development of display technology, flexible display products are more and more widely used. During the preparation or use of the flexible screen, it is usually bent. However, there are multiple signal lines inside the flexible screen, usually made of metal, which is relatively brittle, and the bending action can easily lead to the bending of the signal lines. Stress concentration, cracks, or even fractures occur, which adversely affects the production yield and service life of the flexible screen. Contents of the invention [0003] The technical problem mainly solved by the present application is to provide a flexible screen body, which can improve the bending resistance of the flexible screen body. [0004] In order to solve the above technical problems, a technical solution adopted by this application...
