Description

Technical Field

[0001] The utility model relates to the technical field of flexible screens, in particular to a flexible display screen with a curved surface design. Background Art

[0002] The traditional outdoor curved screen system is composed of several flexible display screen modules. Each flexible display screen module is composed of a screen, a back frame, and a circuit board. There is a back frame mechanism on the back of the screen to realize the docking between the screens and the installation of the screen in the whole system.

[0003] However, the screen back frame will increase the thickness of a single flexible display screen module, resulting in a reduction in the bendability and flexibility of the overall display screen module. At the same time, the display screen modules are docked through a strong connection mechanism such as screws and other structures, and the assembly of the whole curved screen system is not fast and convenient enough. Therefore, a new flexible display screen with a curved surface design is proposed to solve the above problems. Summary of the Utility Model

[0009] An elastic joint is inserted into the positioning hole, and an elastic head is fixedly connected to the end of the elastic joint. The elastic head is snapped into the locking hole.

[0010] Preferably, according to any of the above solutions, the protective layer, the display layer, and the flexible base layer of the display screen body are bonded by an adhesive. The protective layer of the display screen body is specifically an explosion-proof film.

[0011] Adopting the above technical solution: The flexible display screen with a curved surface design is connected to a video signal source and a power supply through the port.

[0012] Preferably, according to any of the above solutions, the display layer of the display screen body includes LED lamp beads, a flexible substrate, and a driving circuit.

[0013] With the above technical solution: The protective layer of the display screen body plays a role in protecting the internal display structure from external physical damage, such as preventing impacts and scratches.

[0014] The display layer of the display screen is the core part of this device, responsible for displaying images and videos. The LED lamp beads are arranged on the flexible substrate in a specific manner. By controlling the brightness and color of each LED lamp bead, various images and videos can be presented.

[0015] The flexible substrate is usually made of flexible materials such as polyester film or polyimide film, which enables the display screen to adapt to various curved shapes and has good flexibility and plasticity.
