Advantages and wide application of LED rental screen

With the maturity of LED display technology, LED outdoor surface mount full-color mass production. Makes the LED rental display widely used in the light and shadow industry! This is also one of the focuses of future promotion! Collect and summarize some knowledge about LED rental screens here, hoping to help the majority of LED display workers!

LED rental screen (LED screen rental) is a special LED display screen used for stage performances and cultural activities. It usually appears in the form of rental, so it is named LED rental screen.

It is widely used in stage leasing, singing and dancing evening parties, various conferences, exhibitions, stadiums, theaters, auditoriums, lecture halls, multifunctional halls, conference rooms, performance halls, discos, nightclubs, high-end entertainment discos, etc., LED rental Compared with the traditional fixed screen, the screen has the following advantages:

  1. Lightweight, ultra-thin

The box of the traditional LED display is mainly SPCC (cold-rolled steel plate), commonly known as “iron box”. The thin plate is made into the shape of the box through processes such as bending, welding, and spraying; the cost is relatively low, but its disadvantages are: The box is too heavy, and the weight per square after the display screen is over 60kg, which is very heavy. The LED rental screen boxes used in the stage performance industry are basically die-cast aluminum boxes. The weight of the die-cast aluminum boxes is about 30-50kg/m2, which has the characteristics of lightweight and good thermal conductivity.


  1. A small error, zero stitching

Because the traditional LED display box adopts sheet metal processing methods, iron or aluminum plates are processed by bending and welding production processes. Due to the large error of such processing technology itself, it is easy to deform after processing, so the error is Millimeter level, it is difficult to meet the requirements of the display screen for zero stitching.

LED rental screen die-cast aluminum box body adopts the production process of module forming and machining, which can control the error within one-tenth of a millimeter, which can completely meet the requirements of zero seam.

  1. Quick installation

Because the cabinet is made of die-cast aluminum, it is lighter in weight, more accurate, and convenient and quick to disassemble. The technicians can splice a single cabinet within a few minutes, which greatly shortens the installation and disassembly time and saves labor costs.

  1. Long lifespan

The main component that affects the life of the LED display is the light-emitting diode (lamp). High temperature is the big killer of the light-emitting diode. The good heat dissipation and thermal conductivity of the aluminum box make the ambient temperature relatively stable, which can greatly extend the display screen. life.

Signal processing: RTF series products adopt signal folding technology, unit modules do not need to be cascaded, which greatly improves the display performance of the product. Using signal folding technology, unit modules do not need to be cascaded, greatly improving the display performance of the product;

Mask: It adopts a matte black mask. The rear buckle is used to fasten the mask. The LED light can be easily maintained in the front. The fastening screws are not visible on the front of the mask. The screen surface has good integrity and there are no screws when the screen is lit. Bright spots caused by light leakage;

Modules: Large modules are used, with only 4 modules per cabinet, reducing internal connections and improving product stability. Without opening the box, the display module can be directly disassembled from the rear of the box.

Back cover: Remove 4 screws and remove the back cover to maintain and replace the power supply and receiving card;

Radiator plate: The aluminum base plate is used to replace the traditional plastic bottom shell, which improves the heat dissipation performance of the product while ensuring flatness;

IC and driver: high refresh rate, high grayscale, high refresh rate, high grayscale 16384 grayscale products use high-end constant current driver chips with built-in PWM. In the case of a single receiving card loaded, the display refresh frequency can be as low as 960HZ and as high as 4800HZ. The gray level is up to 16bit, and the picture is stable, which can easily meet the requirements of high-end applications such as stage performances and broadcasts. The DC power cord adopts American standard wire, the power input adopts a surface mount socket, the power cord is not easy to lose, the line loss is minimal during the power transmission, and the input voltage is stable;

Compatible: The new structure design meets the requirements of hoisting and stacking, as well as indoor and outdoor requirements. Single cabinet, compatible with multiple pitches, compatible with indoor and outdoor modules;

High: High grayscale and high refresh rate design, grayscale 14 bit, refresh frequency >960Hz;

Low: Excellent heat dissipation design and heat dissipation performance, no external fans, air conditioners, etc., low noise; lightweight of the cabinet, low installation cost; low power consumption of the cabinet, saving operating costs;

The good waterproof effect, with IP65 protection level, suitable for outdoor rental use;

Equipped with various specifications of the air box, which is convenient for storage and transportation of the box, and has a good protective effect on the LED display.

How to install indoor LED display?

In order to let more friends understand the installation of LED display, as a professional manufacturer of LED display in the industry, it is the responsibility and responsibility to introduce the correct installation method of the LED display to friends. The following are installation instructions and precautions for indoor LED display magnets, please refer to:

  1. Make a steel frame structure (made according to the size requirements of the drawing), and then fix the finished shelf on the wall or hang it. can.
  2. First, connect the module power cord to the power supply, each power supply is connected to two one-to-three or three one-to-two power cords, according to the manufacturer’s configuration number, pay attention to the positive and negative polarity, the red wire is connected to the positive and the black wire Connect to the negative pole. Then fix the power supply in the corresponding position and fix it according to the position of the drawing. Connect the power supply directly to the 2.5 square cables, and pay attention to the live wire and the neutral wire not to be reversed. Usually, the red wire is connected to the live wire (L), the blue wire is connected to the neutral wire (N), and the yellow wire is grounded. The wiring sequence must be uniform and cannot cross;
  3. Fix the receiving card in the corresponding position, and fix the position according to the drawing. Connect the power cord of the card to the output end of the power supply in the same way as the power cord of the module. The power terminal of the receiving card is marked with positive and negative poles or 3-6V and GND. The GND terminal is connected to the black wire, and the 3-6V terminal is marked to be connected to the red wire. Don’t reverse it. Then insert the long flat cable into the receiving card. There are many sizes of the long flat cable. Pay attention to the order of length according to the distance between the card and the module. Do not plug the cable backward. Generally, the sockets are fool-proof and are not easy to plug them backward. Then connect the receiving cards in series with a network cable. Now the network port of the receiving card basically has no distinction between input and output. The previous old card should be in the order of left in and right out. The serial sequence of the network cables should be connected in a U-shaped or N-shaped sequence, and do not cross randomly;
  4. Put the magnets on the module. Generally, there are 4 magnets on each module (that is, four magnets on the opposite corners). Generally, the standard configuration of the manufacturer is 4 magnets for each module. According to the size of the module and the module on-site, The actual weight of the magnets is subject to the ability to hold the module. Insert a short cable into the output end of the module (for the output of the module to the input end of another module). Fix the modules on the steel frame in order, pay attention to the space between the top, bottom, left, and right when installing, do not misalign, and the flatness should be consistent. The long cables from the receiving card to the module are arranged in order from top to bottom. Start the installation from top to bottom. Each module must have a cable and power cord connection, which can not be omitted. After installation, you can power on and debug.
