In the prior art, when a transparent display screen has a dead pixel, the whole LED display unit can only be wasted, which causes the phenomenon of resource waste. And the traditional glass transparent display screen has complex manufacturing process, large installation difficulty and is not bendable and easy to damage.
SUMMERY OF THE UTILITY MODEL
According to the problem that prior art exists, the utility model discloses a flexible transparent LED display screen, concrete structure includes: the film comprises a base layer film and is located at the bottommost layer, a transparent conducting layer is arranged on the upper surface of the base layer film, an LED array and an FPC connector are arranged on the upper surface of the transparent conducting layer, the LED array is connected with the FPC connector, and a high-transparency protective film is arranged on the upper surfaces of the LED array and the FPC connector.
The LED array comprises LED lamps with driving functions, the LED lamps with the driving functions are arranged according to an MXN array, the LED lamps with the driving functions are sequentially connected in a serial cascade mode, and a plurality of columns of the LED lamps with the driving functions are connected with one FPC connector according to different combinations.
The LED array connected with one FPC connector is an LED unit, when an LED lamp in the LED unit is damaged, the unit including the FPC connector can be cut together, and a new LED unit is spliced and replaced.
Since the technical scheme is used, the utility model provides a pair of flexible transparent LED display screen, this LED display screen adopt multiseriate LED lamp parallel connection on a FPC connector, if certain LED lamp damages like this can directly dismantle the unit that whole FPC connects as a whole, the reuse is a good LED unit of taking FPC and is spliced the restoration with former display screen, reaches save material's effect like this. In addition, the flexible transparent LED display screen is made of materials such as PET (polyethylene terephthalate), so that the display screen disclosed by the application has the advantages of being bendable, light, thin, soft, good in light transmission and the like. In addition, the display screen can be cut and spliced and can be made into a special-shaped display screen, so that the special-shaped display screen can be applied to an environment with a small installation space.

Detailed Description
For making the technical solution and the advantages of the present invention clearer, the following combines the drawings in the embodiments of the present invention, to the technical solution in the embodiments of the present invention is clear and complete description:
as shown in fig. 1 and fig. 6, a flexible transparent LED display screen specifically includes: a base film 11, a transparent conductive layer 12, an LED array 13, an FPC connector 1, and a high transparency protective film 15. The LED array 13 adopts the LED lamps 2 with the driving function, and the LED lamps 2 are connected in series, so that multi-column cascade connection and single-column cascade connection can be realized. Each row of cascaded LEDs only needs four wires of VCC, GND, DATAIN and DATAOUT, a schematic diagram of two rows of LEDs cascaded together in a flexible transparent display screen is shown in fig. 1(a), LEDs in even rows are arranged in a forward direction, LEDs in odd rows are arranged by rotating 180 degrees, and two adjacent rows of LEDs share one VCC or GND. Fig. 1(b) is a single-column cascade, and there is no common conducting wire between each column of LEDs, where VCC and GND are connected in an external controller through an FPC connector. The four wire LED leg definitions are shown in fig. 3.
The flexible transparent LED display screen adopts the LED lamp 2 with a driving function, wherein the LED lamp with the driving function is divided into four lines of VCC, GND, DATAIN and DATAOUT and six lines of VCC, GND, DATA1IN, DATA1OUT, DATA2IN and DATA2OUT (wherein DATA2IN can be pins of a synchronous clock, a redundant input and the like), and the six lines of LEDs are shown in FIG. 4. The four-wire LED array with the driving function takes 8 × 8 as an example, and all LED lamps on a display screen can be connected by only one 24-pin FPC for display of a controller, so that the number of external connectors is saved. According to the practical application requirement, the line width of a power supply can be increased to improve the power supply current of the LED, and a plurality of pins can be adopted in the FPC to share one VCC and GND. An LED array of size 8 x 8 can be implemented with 2 FPC connectors as shown in fig. 2. Fig. 5 is a schematic diagram of a flexible transparent display screen of 16X16 LEDs formed by 8 FPCs.
After the flexible transparent LED display screen has the dead spots, the FPC connectors which have the dead spots can be cut out as a group, and then a group of intact flexible transparent LED units with the FPC connectors are spliced with the cut LED display screen, so that a complete flexible transparent LED display unit can be repaired through simple operation. When the FPC connector is used as a unit for cutting and replacing, the operation is more convenient without disassembling the FPC connector. Complicated display screens such as required special-shaped screens and curved screens can be spliced by taking the FPC as a small unit, and the realization and the operation are simple and convenient.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
