Flexible LED (Light Emitting Diode) display screen

Abstract

The invention discloses a flexible LED (Light Emitting Diode) display screen which comprises screen body cloth, a plurality of rear pressure plates and a plurality of LED unit modules. Each LED unit module comprises a shell, a lamp plate and a plurality of LED lamps. The LED lamps are arranged on each lamp plate in an array with at least two rows and two lines. Each lamp plate is arranged in the corresponding shell. The lamp plate of each LED unit module is connected to the front side of the screen body cloth, so that the LED unit modules form an LED unit module array on the screen body cloth. The rear pressure plates are arranged on the rear side of the screen body cloth, each rear pressure plate is respectively opposite to each LED unit module, and a fixed hole is arranged in the screen body cloth. A fixed piece passing through the fixed hole fixes the rear pressure plates on both sides of the screen body cloth with the LED unit modules.

Description

technical field [0001] The invention belongs to the field of LED displays, and in particular relates to a flexible LED display screen. Background technique [0002] At present, the known LED display screen structure is basically a box structure, that is, multiple hard LED display unit boards are fixed on a box to form a single LED display module, and these modules are spliced ​​and combined during use. Form a LED display screen, connect the power supply and control system, and play various text and video images. Such LED display has the following characteristics: [0003] 1. The smallest unit (LED display module) that makes up the LED display is rigid and cannot be bent and deformed. Therefore, the general LED display is also rigid and cannot be bent and deformed. It is very difficult to make a heterosexual LED display; [0004] 2. The volume and weight are large, and it is difficult to transport as a whole. During installation, the pre-adjusted LED display needs to be dis...

AI Technical Summary

Problems solved by technology

[0003] 1. The smallest unit (LED display module) that makes up the LED display is rigid and cannot be bent and deformed. Therefore, the general LED display is also rigid and cannot be bent and deformed. It is very difficult to make a heterosexual LED display;

[0004] 2. The volume and weight are large, and it is difficult to transport as a whole. During installation, the pre-adjusted LED display needs to be disassembled and packaged, transported to the construction site, and then the separated LED unit display module is reassembled and debugged before it can be put into use. , if it is to be used mobile, it needs to be disassembled and transported repeatedly, which brings difficulties to the installation and transportation of LED display screens and consumes a lot of manpower, material resources and financial resources

[0005] There are also some flexible LED displays currently on the market, such as fixing a single LED light on the cloth, and then connecting these LED bulbs with wires on the back of the cloth, and connecting the control part to form a flexible LED display. It is difficult for the flexible LED display to keep the whole cloth LED display on the same plane, and the LED light has the characteristic of directional light emission. The brightness and color are inconsistent, the image is uneven, and the imaging effect is poor
