Embodiment 1

[0024] like figure 1 As shown, this embodiment provides a foldable LED display screen, which includes one or more LED modules, and each LED module includes several groups of LED light-emitting diodes 102 and a flexible carrier 101 .

[0025] In the production process, LED light-emitting diodes of different colors can be produced according to the different materials of the LED chip, and the LED light-emitting diodes of different colors are produced in batches, and the same package can be used to make LED light-emitting diodes of the same shape and size. LED light-emitting diodes, the LED light-emitting diodes of the same color are classified by a spectroscopic color separation machine, and LED light-emitting diodes of various colors and grades can be obtained.

[0026] For example, in any LED module that forms the LED display screen of this example, each LED light-emitting diode is an LED light-emitting diode obtained by using a spectroscopic color separation machine, and the L...

Embodiment 2

[0045] like figure 2 As shown, on the basis of the above examples, the flexible carrier in this embodiment is a cloth material carrier, for example, canvas is used as a carrier for mounting and fixing each group of LED light-emitting diodes.

[0046] For example, the flexible carrier, i.e. canvas, is composed of two layers of cloth material layer 203 and cloth material layer 204, and each circuit 202, that is, each power line, each signal line, and each drive control module are arranged on the cloth material layer 203 and the cloth material layer 204. Between the material layers 204 , the fabric of the canvas is strong and resistant to bending, and has good waterproof performance, so it can protect and waterproof the circuits 202 and electronic components arranged in the middle.

[0047] Each LED light-emitting diode is arranged on the surface of the canvas, that is, it is arranged on the outer surface of one of the cloth material layers, such as the outer surface of the clot...

Embodiment 3

[0053] like image 3 As shown, on the basis of the above examples, the LED display screen of this embodiment is also provided with one or more identification units 301, and the number of identification units 301 can be set to only one, which is used to identify the LED of this embodiment as a whole. The performance parameters of the display screen; or, the identification unit 301 can also be set in multiples, which are used to respectively identify the performance parameters of the LED display screen of this embodiment according to the performance parameters of each LED module, or set a plurality of identification units 301 to Different performance parameters of the LED display screens of the embodiments are identified respectively.

[0054] For example, only one identification unit 301 may be provided in this embodiment, and each performance parameter of the LED display screen may include the assembly structure and luminous color gamut of the LED display screen, for example, ...

Abstract

The invention discloses a foldable LED display screen, comprising at least one LED module, and each LED module comprises a plurality of groups of LEDs and a flexible carrier; the number and the arrangement mode of LEDs having one color in each group is the same; the LEDs having the same color are of the same sort or of the adjacent sort; the flexible carrier is at least provided with a power cord, a signal wire and driving control modules for the LEDs; a power interface and a signal interface is arranged correspondingly to each group of LEDs, and each group of LEDs is in fixed connection and signal connection with the flexible carrier through the power interface and the signal interface. The foldable LED display screen has the advantages of even display and good display effect, and is convenient in installation and transportation because of the foldable property.

Description

technical field [0001] The invention relates to an LED illuminating device, in particular to a foldable LED display screen. Background technique [0002] In the prior art, due to the influence of various conditions during the production process of each LED lamp, there will inevitably be differences. [0003] Since different customers have different requirements for the accuracy of each LED lamp, and the usage of each LED lamp is also different, therefore, the general lamp screen or display screen manufacturer, after receiving the order from the customer, then produces LED lamps. Manufacturers purchase LED lights. Since LED lights are relatively unstable during storage, they are prone to damage due to vibration, collision, etc. Therefore, LED light manufacturers will not store a large amount of goods in production, and it is difficult for light screen or display manufacturers to buy the same precision. Therefore, manufacturers of lamp screens or display screens generally bu...
