2. In common, the screen size shouldn’t be too large (One cabinet=One LED Display);
3. The LED display screen on both sides can share one LED control card, and it adopts partition control;
4. Hanging installation is the main method, some others will choose the Standing installation.
Chapter 2: Main Classification of Double-sided LED Display Screen
2.1. Double-side Front Opening LED Display Screen
Double-side Front-opening LED screen, which means the screen can be opened from front of the screen. Its main advantage is that the product is mature and there is no need to worry about waterproofing and other related details issues, but its shortcomings are also obvious-too heavy and too thick.
Considering this problem, the design starts with the material and performance of the cabinet, then the aluminum cabinet was produced. So if you need to make this model, according to the different occasions and environments, there is two materials for you to choose: Steel and aluminum. The details as follows:
| Double-side Front-opening LED Display | ||
| Cabinet Material | Steel | Aluminum |
| Density | 7.87g/cm³ | 2.7g/cm³ |
| Cabinet weight | 70kg/㎡ | 58kg/㎡ |
| Melting point | 1538 ℃ | 660.32 ℃ |
| Cabinet thickness | 280-300mm (Without the module) | 180-250mm (Without the module) |
| Cabinet size | Customized according to the demand of project and module size. | |
| Pixel pitch | P3, P3.91, P4, P4.81, P5, P6, P8, P10 | |
| Protect level | IP65 | |
| Application | Usually used for outdoor, if you want, it also can be used indoor | |
| Summary | 1. The density of aluminum is about one-third of steel. Therefore, the weight is much lighter. 2. Aluminum has an excellent corrosion resistance and oxidation resistance. When exposed to air, an oxide film is formed on the surface, it can prevent further corrosion. But Steel will keep oxidizing. 3. Aluminum has better heat dissipation than Steel. | |
Based on these features, here is some advice about installation and goods share with you:
1) If you choose the aluminum LED cabinet, special case is required during installation and transit. Because aluminum is a brittle material, the tensile strength is close to the yield strength, not wear-resistant and not impact-resistant. It’s easy to deform or damage.
2) For the double-side front opening LED Display, the maximum height of the screen cannot exceed 3m (height of single cabinet). Due to the top of the cabinet needs to leave some space to open. That’s why the double-side front-opening LED cabinet cannot be stacked up and down.
Although each model has its own advantages and disadvantages, it will eventually return to the cost. Compared with the aluminum cabinet, the cost of the steel cabinet is much cheaper. When choosing the product, we must consider the detailed installation requirements.
2.2. Double-side Full Front LED Display Screen
Although the double-sided front opening LED display brings many possibilities to different projects. But the thickness of the cabinet and the requirements for the installation environment also violate the demand of some projects. So a front maintenance module is produced to achieve the full front maintenance of the LED screen.
For Full front maintenance double-sided LED display, the cabinet is also made of steel or aluminum. It means that the cabinet size can be customized according to the size of the LED module.
Compared with the Front opening LED Display, the main advantages as below:
1) The thickness of the Cabinet is thinner, saving transportation costs and space.
2) Wider application environment.
3) More convenient for installation and maintenance.
At the same time, there are higher requirements for waterproofing and heat dissipation, so the cost of this model is also expensive than the traditional front-opening LED Display.
Front service module with screws
This model is fixed on the cabinet by screwing the front of the module to achieve front maintenance. However, there are some design problems that make it unable to go far. Like the assembly cost and maintenance cost are too high.
Due to the assembly of the LED screen requires manual operation, when the LED Display is too large, the manual requirements are higher. With the increase of labor costs, it also indirectly affects the price of this goods. If the screws are not in place during the installation process, the water may enter the cabinet, causing the cabinet can’t work properly. So this model is slowly being phased out.
Full front service module
In response to these problems, the market has carried out new design and development, resulting in the Full front service module. Some details are as follows:
| Module size | 250x250mm | 320x320mm | 320x320mm Aluminum bottom |
| Pixel pitch | P3.91, P4.81 | P4, P5.33, P6.67, P8, P10 | P5.3, P6.67, P8, P10 |
| Application | Outdoor | ||
| Cabinet Material | Steel or Aluminum (The size can be customized) | ||
| Thickness | 180mm (Without the led module) | ||
| Disassemble | Free professional tools to remove the module | ||
| Protect level | IP65 | IP68 | |
| Picture |  |  |  |
 | |||
For Non-Aluminum Bottom LED modules, please pay attention to the following installation items:
1) When installing the LED module, if it is not locked in place, the water may enter the screen, so please pay special attention to it during installation or maintenance.
2) Meanwhile, we suggest that you better adopt edging structure, because there will be wiring ports on the side of the Cabinet. Although it has a waterproof design, raindrops may infiltrate under heavy rain. In the face of heavy rain, you can also choose the IP68 aluminum base LED display to avoid it, but the price will be more expensive than the other.
3) Generally speaking, two rings can be added on the cabinet, then you don’t need to disassemble the module to achieve the hanging installation.
2.3. Ultra-thin Double-sided LED Display Screen-250 Series LED Screen
Previous two type double-sided LED display are mainly used for outdoor screen, but 250 Series is specially design for the indoor double-sided LED display screen. The available pixel pitch is indoor P1.95-P3.91mm.

Taking into account the magnetic design of the module, in order to avoid collisions during transportation, some customers will require the module and the cabinet to be packaged separately. It means you must to assemble the screen by yourself.
2.4. Double-sides Transparent LED Display
For transparent LED display, what we saw commonly are one side mode, only one side is prepared to show images, double sides types are relatively rare. What are Double Sides Transparent LED Displays? Take it in short, double sides Transparent LED Displays are simply two faces of display which made overlay together, to realize the double sides showing effect.

3) Higher transmission of light
Transparent LED Display usually take glass as the carrier, reach the affection of information transmit, without effecting the building day-lighting. As the origin of its crystal clear outlook, some factories call it ice-screen, means clear and white like a shinning ice.
The appearance of transparent or double sides transparent LED Display like a high transparent window-shades, reduces the structure frame shelter of eyesight, so the transparency rate could rise to 50%-90%. That makes it become the most higher definition and perspective affection products among LED screens.
4) Novelty Mode with Sense of Science and Tech
It made break through of the single mode of one side type in performance and operations. Like installing in the middle of the super market, then both visitors in two sides passed by could bet the sight and content on it; or it could also use as glass curtain wall, the inside surface could offer exhibition to indoor customers and outdoor provide image for street passengers. The novelty special viewing experience makes you feel like watching the image floating on glasses without effecting the light transparency function.

This kind of information can display two-dimensional, three-dimensional animation, video, TV, VCD programs and live events. The screen can play different contents on two side as requirement.
Chapter 4: How to Setup the Double-sided LED Display
1. Control system
According to the LED display size and resolution, the control system will be different. If the LED screen resolution ≤2300000dots, you can choose Synchronous system(Computer/PC control) or asynchronous system (WIFI/3G/4G control). Due to the limit of the asynchronous LED control system, if the resolution＞2300000dots, you just can control the screen by the computer (Synchronous system).
Usually, we adopt the Novastar/ Xingwei/Huidu/Xixun/Colorlight and others as the control system.
2. Connection of the screen
Power connection: each power cables just can load 3.5-4KW, then you need to change another cables to connect the cabinet.
Signal connection: each data cables, max support 650000 dots. Once exceeded, you need to change the second data cable to connect.
If it is a screen composed of several cabinets, divide the double-side screen into side A and side B. In this case, we suggest connecting side A and side B of the cabinet together, and control them through the same control card. Or directly connect the A side and B side in series, and then control them together.
3. Set up the LED Screen
It means you need to set up the RCG File and connect file in the control software. Usually the configuration file, the supplier will provide it at the time of shipment. The connection file needs to be made according to the actual connection of the cabinet and the number of receiving card. If you don’t know how to make it, please check the below link:
/new/diy-led-display-novastar.html
For example:
Pixel pitch: 10mm
Screen size: 2240*1120mm (Double-side)
Cabinet size: 1280*1120mm+960*1120mm (Double-side)
Novastar control system: TB3 (Max support 650000 dots)
Then the total resolution is 224*112*2 dots
Don’t think of it as a double-side screen, think of it as a big screen, like 4480*1120mm or 2240*2240mm. Then everything will be very easy.
Regardless of whether the two sides of the LED display screen are to show the same content or different content, it is set by the coordinates in the playback software.
