[0017] Unless otherwise defined, all technical and scientific terms used herein are same as the meaning understood by the person skilled in the art belonging to the technical field of the utility model;The terms used in the specification are only for the purpose of describing the specific embodiment, not intended to limit the utility model;The specification and claims of the utility model and the above drawing explanation of the terms "include" and "have" and their any deformation, intent is to cover the non-exclusive inclusion.The specification and claims of the utility model or the above drawing of the terms "first", "second" etc.are used to distinguish different objects, not for the purpose of describing a specific order.

[0018] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figures 1-4 As shown, a flexible display module includes a flexible circuit board 1, on which multiple LED beads 2 are soldered. A flexible support member 3 is provided on the upper surface of the flexible circuit board 1, and a flexible display film 4 is provided on the upper surface of the flexible support member 3. The flexible display film 4 has a light-transmitting area 41 and an opaque area 42. The light-transmitting area 41 corresponds to the position of the LED beads 2, and the light emitted by the LED beads 2 can pass through the light-transmitting area 41 and be emitted outward. The opaque area 42 is coated with opaque ink. When the light emitted by the LED beads 2 shines on the opaque area 42, it will be absorbed by the opaque ink and cannot pass through the flexible display film 4.

[0021] During use, power is supplied to the flexible circuit board 1, which illuminates the LED beads 2. The light emitted by the LED beads 2 passes through the flexible support member 3 and shines onto the flexible display film 4. The light then passes through the light-transmitting area 41 on the flexible display film 4 and is emitted outwards, allowing the user to view the content displayed by the module from the outside. This flexible display module utilizes the flexible circuit board 1, the flexible support member 3, and the flexible display film 4, enabling it to be easily bent and thus suitable for installation on curved surfaces and even irregularly shaped curved surfaces, improving its versatility.

[0022] To ensure that the light emitted by the LED beads 2 can smoothly illuminate the flexible display film 4, clearance holes 31 are provided on the flexible support 3 at corresponding positions to the light-transmitting area 41. The light emitted by the LED beads 2 can pass through the clearance holes 31. In use, the light emitted by the LED beads 2 passes through the clearance holes 31 and then illuminates the light-transmitting area 41 of the flexible display film 4 to achieve normal display function. The flexible support 3 serves two purposes: firstly, it provides support and improves structural rigidity; secondly, it reduces light leakage between the LED beads 2 and improves the display effect.

[0023] In this embodiment, the flexible support 3 is made of PU elastic foam. In other embodiments, the flexible support 3 may also be made of other flexible materials.

[0024] In this embodiment, the upper and lower end surfaces of the flexible support 3 are respectively bonded and fixed with the flexible circuit board 1 and the flexible display film 4 by glue. In other embodiments, the flexible circuit board 1, the flexible support 3 and the flexible display film 4 can also be fixed by other connection methods, such as screw connection.

[0025] In order to adapt to the display requirements of different products, display patterns 43 are arranged on the light transmission area 41 of the flexible display film 4. According to different display requirements, corresponding display patterns 43 can be arbitrarily arranged. When the light emitted by the LED lamp beads 2 irradiates on the display patterns 43, the display patterns 43 appear bright from the outside, which meets the normal display requirements. The display patterns 43 can be arranged on the light transmission area 41 of the flexible display film 4 by silk printing, pasting and other methods.

[0026] In order to improve the uniformity of display, in this embodiment, the interval between two adjacent LED lamp beads 2 on the flexible circuit board 1 is not more than 2.5 mm. By controlling the interval between the LED lamp beads 2, the light emitted by each LED lamp bead 2 can be mixed in the avoiding hole 31, so that the light emitted by the LED lamp beads 2 is more uniform when irradiating on the light transmission area 41, which improves the display effect of the flexible display module.

[0027] The above specific embodiments are the preferred embodiments of the utility model, and the utility model is not limited by this. The scope of the utility model includes but is not limited to the specific embodiments. Any equivalent changes made according to the utility model are within the protection scope of the utility model.
