Description

TECHNICAL FIELD

[0001] The present application relates to the field of screens, in particular to a flexible screen. BACKGROUND

[0002] As a new type of display technology, flexible screens have been widely used in electronic products, especially in scenarios where space is limited and lightweight and bendable characteristics are required, such as electronic cigarette display screens. However, traditional flexible screens usually adopt a simple structure of single or double layers, although they can provide basic display functions, in actual use, the screen may be damaged due to external force or long-term use, in addition, such flexible screens are usually relatively complex to maintain and replace, especially when replacing or repairing internal components, users usually need to disassemble the entire device, making the maintenance process very inconvenient.

[0003] In view of the maintenance convenience of flexible screens, some improvement schemes are proposed in the prior art, for example, some technologies add an easily detachable adhesive layer between the flexible screen and the supporting structure, or adopt a modular design, so that the flexible screen is more convenient to disassemble and assemble. In addition, some schemes optimize the structural design of the flexible screen to reduce the influence on other components during disassembly and assembly, thereby improving the convenience of maintenance. Although these technical solutions improve the maintenance efficiency to some extent, there are still many problems in actual application, such as insufficient strength of the adhesive layer, loose connection of the modular design, etc.

[0004] Although the prior art has made some efforts in function division and maintenance convenience, there are still significant defects, specifically, the integrated flexible screen structure is still very complex to maintain, because the various functional layers are not clearly divided, resulting in that the faults cannot be handled or replaced locally, in addition, the modular design in the prior art can improve the maintenance problem, but it cannot completely solve the maintenance problem brought by the integrated structure, the overall function division is still not clear enough, which may affect the stability and long life of the screen in actual use. These problems show that it is still a challenge to optimize the maintenance of the flexible screen when designing the flexible screen. CONTENT OF THE INVENTION
