Is LED Display Expensive? A Complete Guide To Avoid Pitfalls When Purchasing
I am a sales veteran who has been deeply involved in the LED display industry for more than ten years. I have handled thousands of projects, ranging from large screens on theater stages to outdoor advertising screens in shopping malls. Many purchasers have actually consulted a lot of relevant information on their own before coming to me for consultation. However, when a group of people actually sit down to discuss specific needs, they can clearly notice that they often overlook many key details. The LED display industry is really well hidden. From the appearance point of view, they are all screens that function as luminous displays. However, if we consider the actual disassembly, every inconspicuous detail, from the particle size on the screen surface to the internal control system configuration, will have a real negative impact on the final display effect and overall service life of the project.
How much does an LED display cost?
This is the most frequently asked question, but there is no standard number for the answer. The price of LED display screens ranges greatly, from a few thousand yuan to millions. The key is to understand the composition of the quotation. The core factor that affects the price is the pixel pitch, which is often referred to as the P value - P1 means that the pixel pitch is 1 mm. The smaller the value, the higher the definition and the higher the cost.
Outdoor large screens usually use products such as P10 or P8 with larger pixel pitch, and the unit price is relatively low; indoor high-definition displays mostly use precision models such as P2.5 or P1.8, and the price naturally goes up. In addition to pixel spacing, brightness requirements and protection levels including refresh rate and other related parameters will be reflected in the actual quotation. Some purchasers will only ask "What is the price of a P meter per square meter?" It is extremely difficult to obtain accurate and standard answers by asking this way, because the gap between different manufacturers' brands and different series of configurations may be several times different.
After getting this quotation, you must carefully check all the details of every parameter. Some unscrupulous or even unscrupulous manufacturers will secretly use recycled chips found from everywhere, as well as low-quality lamp beads with extremely low prices to deliberately suppress the extremely low price. Those low-quality products that are manufactured will definitely have strange problems such as extremely obvious rapid brightness attenuation and extremely high probability of dead lights after being used for a year or two. It is quite uneconomical to calculate the total when the total is calculated.
How to choose the model of LED display screen
When choosing a model, you can’t just look at the appearance and price. It must be determined based on the actual usage scenario: outdoor environments require high brightness and strong protection, with a brightness of at least /㎡ and a protection level of IP65; indoor environments require lower brightness, around /㎡ is enough, and the viewing angle and viewing distance must be considered.
The smoothness of the footage captured by the lens is all determined by the refresh rate of the screen parameters. Especially in scenes where the screen and camera are required, you must carefully select the configuration, and even models with higher performance values are more reliable. For ordinary exhibition display needs, two thousand hertz can be used very well and is suitable enough to meet the needs. There is really no need to spend a lot of extra money on unnecessary special parameters that most people cannot use.
The size of the cabinet and the splicing method are also very important. The use of modularization can reduce the convenience of later maintenance and replacement. The cabinet specifications of different manufacturers are different, and the selection and finalization must be made based on various actual on-site conditions. The gray level directly reflects the delicateness of the picture. Higher-end products can directly reach the level of 16bit or even higher levels.
Which brand of LED display is better?
There are many brands of LED display screens on the market, with high and low quality levels. First-tier brands such as Leyard, Unilumin, and Absen have stable and excellent product quality and a well-established after-sales system, but their prices are relatively higher than most common mid-to-high-end categories. When these brands undertake large-scale projects, they have a large and sufficient collection of cases, which is suitable for customer groups with relatively high demands and requirements for stability and after-sales service.
Second-tier brands also have many cost-effective options, suitable for small and medium-sized projects with very limited budgets. Domestic small and medium-sized brands also have unique advantages in specific fields. For example, a few brands that focus on small-pitch displays have done quite well in indoor display fields such as conference rooms.
When inspecting manufacturers, you need to check and accept various relevant cases and qualifications. You have to see if there is experience in similar projects. The length of the warranty period and the actual response speed of after-sales service are also key considerations. Although some well-known brands have low selling prices, the after-sales quality of brands that cannot keep up with them will not be able to find someone to contact them if there is a minor problem.
What to pay attention to when installing LED display screen
The installation process directly affects the use effect and life of the display; it is necessary to confirm the load-bearing capacity of the installation site first: the LED display has a heavy weight, plus brackets and various structural parts, the wall and even the steel structure must be able to withstand the corresponding load; outdoor installation still needs to consider the wind resistance level, especially the installation risk on the exterior walls of high-rise buildings is greater.
The power distribution system must be independently configured and the power reserve must be sufficient. It is recommended to configure the distribution box according to 1.3 times the rated power of the display screen to avoid tripping or line heating caused by full load operation. The signal line should be a dedicated line and should be avoided in parallel with strong current lines to prevent interference from affecting the display effect.
The installation and debugging process must be handled by professionals. Improper parameter settings may cause color deviation or synchronization problems. When carrying out construction in the rainy season, attention should be paid to waterproofing, and joints must be sealed solidly and completely. After debugging, an aging test must be carried out, and it must be continuously operated for more than 24 hours to confirm that there are no problems before it is delivered for use.
Does LED display need maintenance?
LED displays are electronic devices with extremely low power consumption. Daily maintenance is relatively simple, but they must not be left alone. Regularly cleaning the dust on the surface is the basic action. Use a soft brush or compressed air to remove the accumulated dust in the gaps of the box and the heat dissipation holes. Poor heat dissipation will cause the lamp beads to accelerate the attenuation of light.
Conduct a quarterly inspection of the firmness of the power cord connection. If any looseness is found, prompt treatment is required. When a single module has a dead light or abnormal brightness, it should be replaced immediately to prevent the overall display effect from being affected. The control system software also needs to be regularly upgraded to repair existing problems.
If it is not used for a long period of time, it is recommended to power on and run it once a month to maintain the activity of the components. In the future, we should focus on checking the waterproof condition of outdoor screens in various extreme weather conditions, so as to detect and deal with leakage problems as soon as possible. With sufficient daily maintenance, the life of the LED display can definitely be extended to more than five to eight years.
