Installation Method for LED curtain screens in Glass Showcases
LED curtain screens are installed behind glass, primarily using glass support brackets, window sills, or the upper and lower positions of the glass to secure them. Therefore, when designing the transparent screen, the screen’s weight is kept very light horizontally, with a weight of less than 10 kg per square meter.
Depending on the installation scenario, LED curtain screens can be installed using the following methods:
- Hanging Installation:
The screen is hung using hooks and beams, and the transparent screen boxes are connected through quick locks or connectors. This method is suitable for applications in stages, storefronts, and shops.
- Point Support Installation:
The boxes are fixed to the glass curtain wall structure using a combination of clamping rings. This method is commonly used in architectural glass curtain walls.
- Frame Installation:
The screen boxes’ frames are directly fixed to the glass curtain wall structure using composite bolts, without the need for any steel structure. This is also applied in architectural glass curtain walls.
- Fixed Stacking Installation:
Transparent screen boxes are secured on a truss using connectors. This installation method is suitable for exhibition halls, auto shows, and events.
Installing an LED curtain screen is relatively easy compared to conventional screens. Even individuals with limited experience can quickly learn how to install them after a few tries. If you want to know how to install an LED curtain screen, let’s take a closer look below.
LED curtain screen Installation Steps:
- Install the suspension beams. Choose the desired location for installing the suspension beams, and make sure the two beams are level.
- Connect the LED curtain screen boxes to the suspension beams. Use the designed mounting holes to attach the boxes to the beams, and secure them with locking clasps or connector pieces to firmly fix them in place.
- Connect the boxes in the left and right rows. These are also connected using corresponding locking clasps, making it a straightforward process.
- Connect the boxes above and below. Easily align the upper and lower boxes by using the positioning holes and secure them with locking clasps.
- Connect the wiring between the boxes. After connecting the boxes, it’s time to link the wiring between them. Use aviation connectors to connect the corresponding data and power cables from top to bottom.
- External power cable connection. Use specialized aviation connectors to connect the live wire, neutral wire, and ground wire of the power cable. The number of external power cables corresponds to the number of columns, and you can connect them from the top or bottom, depending on your specific requirements.
- External network cable connection. Connect one end of the network cable to the processor and the other end to the screen.
- Connect the network cables between the boxes. After the first column of boxes is connected to the network cable, you’ll need to use another cable to connect two columns of boxes, creating an N-shaped network cable connection layout.
These are the installation methods and steps for installing an LED curtain screen on glass. LED curtain screens are not only lightweight, thin, and easy to install, but they also offer unparalleled pixel pitch and high transparency. In terms of control and operation, they are intelligent and can easily handle tasks like loading, deleting, and settings, making them user-friendly even for store personnel. Additionally, remote cluster control is possible, catering to various application and control requirements.
How much power would the LED curtain screens consume per month?Â
Is the power consumption of LED curtain screens high? Many people have this question. To answer this question, several factors need to be considered, primarily the screen area and display brightness. Let’s delve into it:
LED curtain screens differ from regular LED displays. When playing advertisements, they don’t emit unnecessary background light; they only display the content, making the black areas non-emissive, creating a transparent effect. This playback method significantly reduces light pollution and can reduce energy consumption by at least 30% compared to conventional LED displays. The power consumption of an LED curtain screen is influenced by the screen area, usage time, average power consumption, and brightness. It’s easy to understand that with the same configuration, a larger screen area and longer playback time will consume more power. Higher brightness requires more power to display, which also increases power consumption.
Let’s take an example of an outdoor P3.91 LED curtain screen from LEDKUL:
Low Brightness Configuration for P3.91 Power Consumption and Electricity Cost:
Low brightness configurations have a brightness of around 1500 cd/m² and are typically used in pure indoor environments, such as exhibition halls and galleries. The average power consumption is approximately 120W/m². For a 1m² screen used for 10 hours, the power consumption would be 120W × 10h × 1 = 1200W, which is equivalent to 1.2 kWh. Calculating at an industrial electricity rate of 0.12 USD per kWh, the electricity cost is 0.144 USD. If the screen area is 30m² and played for 25 days a month, the monthly electricity cost would be 0.144 USD × 30 × 25 = 108 USD.
High Brightness Configuration for P3.91 Power Consumption and Electricity Cost:
High brightness configurations have a brightness of around 5000 cd/m² and are generally installed indoors or for outdoor displays in brand stores’ glass showcases. The average power consumption is approximately 240W/m². For a 1m² screen used for 10 hours, the power consumption would be 240W × 10h × 1 = 2400W, which is equivalent to 2.4 kWh. Calculating at an industrial electricity rate of 0.12 USD per kWh, the electricity cost is 0.288 USD. Assuming a total screen area of 30m² and played for 25 days a month, the monthly electricity cost would be 1.92 USD × 30 × 25 = 216 USD.
The above is a preliminary method to assess the power consumption and calculate the electricity cost of LED curtain screens.
It’s worth noting that the content being displayed also affects power consumption. For example, displaying non-transparent images would generally increase power consumption because all the LEDs are emitting light and consuming energy. However, LED curtain screens typically display custom content, reducing the occurrence of non-transparent images, so this factor is usually not a significant consideration.
How to Select a high Quality of LED curtain screens?
Some say that the quality of the cabinet can be roughly judged by its appearance. Is this really the case? Currently, many manufacturers produce similar transparent LED panels and cabinets. Even if the appearances may differ, the underlying principles, such as the circuit boards, LEDs, and wiring, are essentially the same. Therefore, you can’t judge the quality solely by appearance; you need to consider the following factors:
- Brightness Comparison:
Place an acrylic panel directly against the same number of modules and slowly raise it a short distance. Observe if the LED brightness meets your requirements. Placing the module directly inside the cabinet can provide a more direct comparison.
- Uniformity of LED Display Colors:
While assessing brightness, pay attention to the uniformity of the LED light. When observing white light, check for color discrepancies (which are quite important). You may not notice color discrepancies by covering the screen with a thin white paper, so you may need a thicker acrylic panel. The absence of color discrepancies is one of the most critical factors differentiating good from bad quality and is a major reason for price differences in LED curtain screens.
- Identifying Wiring:
High-quality wiring should have UL certification. However, relying on the manufacturer’s claims may not be reliable, so the most direct way is to peel back the insulation and count the number of conductors inside. Modules with 15, 17, 19, or even 20 to 30 conductors should not necessarily be worse than modules with 14 or 11 conductors, and vice versa.
- LED Temperature:
After illuminating for a while, touch the LED chips. If they are very hot or even too hot to touch, it indicates poor temperature stability.
- Soldering Quality:
Full soldering indicates good soldering craftsmanship, and higher brightness indicates good soldering with good use of solder. Serious issues like cold soldering can lead to poor connections, causing difficulties in maintenance.
- LED Brand:
The LED brand may not be the sole indicator of product quality, but different LED brands exhibit substantial differences in stability and durability during use, with significant price variations. Therefore, the LED brand is one of the quality assessment standards.
- PCB Board Quality:
The PCB board’s line width, line thickness, and line spacing should meet requirements to prevent overheating, disconnection, and short circuits. Consider the impact of high temperature, humidity, and resistance to special environments. The PCB board should not have any deformation, as it may lead to casing deformation and misaligned screw holes after installation. With modern mechanical assembly, the positioning of holes and lines on the PCB should remain within acceptable tolerance limits.
In addition to the above aspects, assessing the IC and auxiliary components of the LED curtain screen cabinet requires professional expertise for a more accurate evaluation.
