[0074] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0075] It should be noted that, where there is no conflict, the features in the embodiments of this disclosure can be combined with each other.

[0076] In one embodiment, this disclosure provides an LED flexible film screen, wherein...

[0077] The LED flexible film screen includes a first flexible film and a second flexible film, and,

[0078] A flexible interlayer sandwiched between the first and second soft membranes.

[0079] in,

[0080] The first flexible film, the second flexible film, and the flexible interlayer form a multi-layer structure, which serves as the flexible part of the LED flexible film screen.

[0081] The shapes of the first PVC membrane, the second PVC membrane, and the flexible interlayer are all the same, all being the first shape.

[0082] The dimensions of the first flexible membrane, the second flexible membrane, and the flexible interlayer are flush with each other and have the same dimensions, all being the first dimension;

[0083] The flexible interlayer contains multiple LED zones.

[0084] Each LED zone includes multiple LED display units, each LED display unit includes an LED emitter and a flexible circuit connected to the LED emitter, wherein the thickest wire in the flexible circuit has a second dimension that is much smaller than the first dimension.

[0085] In this embodiment, all LED zones are essentially housed within a flexible interlayer. Not only are they protected by the flexible interlayer, but the heat generated by the LED zones during operation (e.g., displaying an image) is also dispersed through the flexible interlayer, the first flexible film, and the second flexible film. This balances flexibility and heat dissipation requirements through the first flexible film, the second flexible film, and the flexible interlayer, preventing localized overheating. Furthermore, the presence of the first flexible film, the second flexible film, and the flexible interlayer allows the LED flexible screen to adapt to complex surfaces such as cylinders, curved walls, and irregular structures, thus overcoming the limitations of traditional rigid screens.

[0086] In another embodiment,

[0087] The flexible interlayer includes a first flexible layer and a second flexible layer.

[0088] The first flexible layer is located on the side adjacent to the first soft membrane.

[0089] The second flexible layer is located near the side of the second soft membrane.

[0090] The plurality of LED partitions and LED display units are disposed between the first flexible layer and the second flexible layer, such that the LED partitions and LED display units are located between the double sandwich formed by the first soft film, the first flexible layer, the second flexible layer and the second soft film.

[0091] In the above embodiments, when the flexible interlayer is considered as a whole, the first flexible film, the second flexible film, and the flexible interlayer actually form a sandwich structure. When the flexible interlayer includes a first flexible layer and a second flexible layer, the LED partition and LED display unit located between the first and second flexible layers are situated between the two interlayers formed by the first flexible film, the first flexible layer, the second flexible layer, and the second flexible film. The double-interlayer structure allows for a balance between the flexibility and strength of the LED flexible film screen.

[0092] In another embodiment,

[0093] The second size is set with reference to the resolution and / or pixel density of the LED flexible film screen.

[0094] In another embodiment,

[0095] The spacing between adjacent LED beads is set with reference to the resolution and / or pixel density of the LED flexible screen.

[0096] It is understood that the second size and the spacing between adjacent LED beads, set as described above, can meet the user's requirements for screen display, such as the resolution and / or pixel density requirements of the LED flexible screen. The spacing between the LED beads can also be further adjusted based on the viewing distance.

[0097] In another embodiment,

[0098] The flexible circuit eliminates the need for a PCB board.

[0099] In another embodiment,

[0100] The flexible sandwich layer is a thermally conductive flexible sandwich layer.

[0101] For example, the flexible interlayer is a thermally conductive silicone interlayer.

[0102] In another embodiment,

[0103] Both the first and second soft membranes are thermally conductive.

[0104] In another embodiment,

[0105] The flexible portion can be bent, folded, and rolled.

[0106] In another embodiment,

[0107] The flexible portion can be cut.

[0108] In another embodiment,

[0109] The LED flexible film screen displays information bidirectionally on the outer sides of the first and second flexible films via LED beads.

[0110] In this embodiment, when both the first and second soft films are soft films with a certain light transmittance and the LED beads are circumferentially emitting beads, the LED soft film screen can naturally display bidirectionally on the outer sides of the first and second soft films via the LED beads, thereby achieving the effect of two-sided light emission.

[0111] In another embodiment,

[0112] On one side of the multi-layer structure formed by the first soft film, the second soft film, and the flexible interlayer, the rigid part of the LED soft film screen is provided, and the rigid part includes a hollow shell.

[0113] In another embodiment,

[0114] The rigid section is used to fix the power supply module and other circuit modules besides the power supply module.

[0115] It is understandable that the power supply module and other circuit modules are at least used to ensure that the LED flexible screen can work properly.

[0116] In another embodiment,

[0117] When the LED flexible film screen is not deployed, the flexible part of the LED flexible film screen can be rolled up to wrap around the rigid part.

[0118] For this embodiment, see Figures 1 to 3 As shown, the dimension of one dimension of the rigid part (e.g., its length) is less than or equal to one edge of the corresponding flexible part, and,

[0119] The maximum dimensions of the other dimensions of the rigid portion (such as its width and height) are much smaller than the other side of the flexible portion, so that the LED flexible film screen can wrap the rigid portion by rolling up the flexible portion.

[0120] In another embodiment,

[0121] The light transmittance of the LED soft film screen is greater than or equal to 80%.

[0122] Typically, the light transmittance is greater than or equal to 80% and less than or equal to 95%. This ensures that the LED flexible screen does not affect the lighting of the space behind it after installation, and also helps to ensure uniform color and no graininess in the image, making it particularly suitable for use in scenarios such as shop window displays or building glass curtain walls.

[0123] In another embodiment,

[0124] The LED flexible film screen is a point-controlled LED flexible film screen, and the thickness of the LED flexible film screen is 3-5mm.

[0125] This is understandable; point control means that each LED can be programmed individually, which is beneficial for achieving pixel-level dynamic effects such as scrolling text, pattern gradients, and particle animations. In other words, each LED is controlled by an independent signal to achieve pixel-level dynamic effects.

[0126] In another embodiment,

[0127] The shell is in the shape of a square tube or a round tube.

[0128] In another embodiment,

[0129] Circuitry can be installed inside the housing.

[0130] For example, the housing can also house circuit modules with PCB circuit boards, including but not limited to power modules and signal processing modules that control the LED beads in the LED light source.

[0131] In another embodiment,

[0132] The display surface of the LED flexible film screen is rectangular.

[0133] The dimension of the shell in one dimension is equal to the length of one side of the rectangle.

[0134] For example, when the shell is square tubular, the length of the square tubular is equal to the width of the rectangle.

[0135] In another embodiment,

[0136] Each LED display unit requires no PCB circuit board.

[0137] Along the direction from one side of the multilayer structure where the rigid portion is located to the other side of the multilayer structure, the LED display unit is provided with at least a first flexible conductor, a second flexible conductor, and a plurality of LED light emitters arranged in sequence.

[0138] in,

[0139] Each LED emitter includes an LED bead, which is a point-controlled LED bead, and its operation is controlled by at least two pins. For example, the two pins are respectively connected to a first flexible wire and a second flexible wire.

[0140] For example, when the LED beads are two-wire point-controlled beads, the LED display unit includes a first flexible wire and a second flexible wire. The first and second flexible wires serve as power supply lines and can also be used to transmit signals to the LED beads in each LED emitter to control their operating state. It should be noted that, in this case, the first and second flexible wires function as power supply lines and are capable of carrier wave transmission, thereby transmitting control signals to each LED emitter and its LED beads.

[0141] Furthermore, when the LED beads are three-wire controlled beads, the LED display unit also includes a third flexible wire. In this case, the first and second flexible wires are power supply lines, and the third flexible wire is a signal line, which is used to transmit signals to the beads in each LED to control their operating state.

[0142] For example, all LED display units are connected in parallel to allow the LED flexible screen to be cut, and the cut LED flexible screen can still function normally as an integral part of the rigid part. For instance, the parallel connection has the following characteristics: all LEDs in each LED display unit only receive DIN signals and do not transmit any DOUT signals externally; a third flexible wire connects each LED as a bus. This allows the cut LEDs to still receive DIN signals and function normally, thus ensuring the LED flexible screen remains integrated with the rigid part after cutting. It should be noted that, in addition to the above parallel connection, all LEDs in each LED display unit can also follow a breakpoint-resume signal transmission method, i.e., the previous LED in the LED display unit receives the DIN signal and transmits the DOUT signal to the next LED. In this case, the LED flexible screen can still be cut as needed after leaving the factory, and the cut LED flexible screen can still function normally as an integral part of the rigid part.

[0143] In other words, in one optional embodiment, the flexible portion can be cut off without affecting the display function of the remaining flexible portion as a flexible film screen.

[0144] For example, the wire diameter of all conductors is determined so as not to significantly affect the visual effect of the LED display unit or the 360-degree light emission of the LED display unit.

[0145] Furthermore, for LED light emitters or LED beads, all necessary circuit components are encapsulated inside the LED light emitter or LED bead, which also avoids faults such as short circuits or poor soldering caused by PCB circuit boards, thus achieving a better structural design for LED flexible film screens.

[0146] In another embodiment,

[0147] Each LED zone can be individually controlled to emit light or not.

[0148] Typically, inactive LED zones can be automatically powered off to reduce energy consumption.

[0149] In another embodiment,

[0150] The materials of the first soft membrane, the second soft membrane, and the flexible interlayer include, but are not limited to, flexible polymer materials such as silicone, PVC, PET, or polyurethane.

[0151] In another embodiment,

[0152] The LED beads are 360-degree circumferential light beads.

[0153] Since the maximum outer diameter of LED beads can be made very small, by means of the sandwich structure embodied in the multi-layer structure disclosed in this disclosure, LED beads and circuits can be easily encapsulated between two layers of flexible film, so that the total thickness of the LED flexible film screen can be controlled within 3-5mm.

[0154] Maintain flexibility.

[0155] Furthermore, in another embodiment, this disclosure also discloses a method for manufacturing an LED flexible film screen, comprising the following steps:

[0156] Two parallel flexible conductors are provided, one first and one second; optionally, a third flexible conductor may also be provided.

[0157] Multiple LED light emitters are arranged sequentially along the directions of the first flexible wire, the second flexible wire, and optionally the third flexible wire;

[0158] Each LED emitter is electrically connected to a first flexible wire, and each LED emitter is electrically connected to a second flexible wire; optionally, a third flexible wire is electrically connected to each LED emitter.

[0159] Repeat the above steps to realize an array of multiple LED light emitters, wherein at least a portion of the array of multiple LED light emitters forms a first LED display unit and its corresponding first LED partition, and another portion of the array of multiple LED light emitters forms a second LED display unit and its corresponding second LED partition;

[0160] All LED display units and their LED zones are covered with thermally conductive silicone.

[0161] The flexible portion of the LED flexible film screen is achieved by wrapping a first soft film and a second soft film on both sides of the flexible interlayer.

[0162] In another embodiment,

[0163] The multi-layer structure formed by the first soft film, the second soft film, and the flexible interlayer serves as the flexible part of the LED soft film screen.

[0164] The shapes of the first PVC membrane, the second PVC membrane, and the flexible interlayer are all the same, all being the first shape.

[0165] The dimensions of the first flexible membrane, the second flexible membrane, and the flexible interlayer are flush with each other and have the same dimensions, all being the first dimension;

[0166] Each LED display unit includes an LED emitter and a flexible circuit connected to the LED emitter, wherein the thickest wire in the flexible circuit has a second dimension that is much smaller than the first dimension.

[0167] In another embodiment, the following steps are also included:

[0168] A rigid section is provided, and the circuit in the rigid section is electrically connected to the flexible circuit in the flexible section.

[0169] See Figures 1 to 3 In another embodiment, this disclosure discloses an LED flexible film screen, which includes a flexible portion 1 and a rigid portion 2, wherein the flexible portion 1 is rollable and the rigid portion 2 is square tubular. Figures 2 to 3 This illustrates the dimensions, with the unit being mm. The display surface of the LED flexible film screen measures 1000mm x 500mm. The rigid, square tubular portion is 500mm long, and the end face of the tubing is square with a side length of 50mm.

[0170] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
