Consider a case that you are rushing to a train station. When you are queuing up, you look up at the scrolling digital signage to search for the train you plan to take. When you get to see it, near it is the platform number that you are unable to see clearly whatever the angle is. As you approach, you finally get to know what causes invisibility——small dark spots appear in a certain regular distribution on the screen.



Why are there small dark spots distributed in a certain pattern on LED walls?

LED walls are modularly designed, consisting of multiple display units. For easy installation and maintenance, modules in most cases are magnetically attached to the LED display units. Metal dust in the air will over time be adhered to the modules to form dark or black spots. As the magnets are distributed at the four corners of the modules, therefore the dark spots come out singly, in pairs or in groups of 3 or 4.


In some indoor or semi-outdoor scenarios like subway platforms and train stations where wheel and track rubs drastically, uncounted metallic dust is easily produced. Another reason is that the train's braking system, such as brake pads and brake discs, also generate friction during braking, leading to metallic dust.


What impacts will metal dust have on LED screens?

These adhered metallic dust not only brings about invisibility, it can even cause LED abnormality as time goes by, including incomplete color display, always-on pixels and dead pixels. What’s worse, metallic dust can even lead to “LED caterpillar” failure, i,e, a line of always-on pixels, significantly impairing visual experience.


Solution to small dark spots with certain regular distribution on an LED video wall

LianTronics’s self-developed “M Dust-shield” Technology employs special materials and unique processing and assembly methods to effectively shield and eliminate the magnetic force on the display surface. By doing so, it inhibits the adsorption of metal dust to the surface of the LED panels, thus avoid dark spot and ensures the clarity and display quality of the screen, enhancing the viewing experience for passengers. Compared with unprocessed LED screens with as high magnetic force as 50Gs, LED screens processed with M Dust-shield are only 1Gs.

LianTronics' "M Dust-shield" Technology addresses the issue of metal dust being attracted to the modules, which leads to the appearance of small dark spots on LED walls.

In summary,"M Dust-shield" Technology provides an effective solution to the problem of metal dust adhering to LED displays in special environments. With its application, LED indoor displays can continue to shine brightly in transportation hubs, retail stores, factories and other critical locations.


Given that the world is going globalize in all aspects, there is no doubt that no business will be immune to the shock of COVID-19. It’s good to look ahead especially for business owners when more and more countries are going to or planning to reopen their economy now. Here’s the discussion of transformations that may inspire companies to take to communicate with customers in the post-COVID world.


1. Pay more attention to brand digital delivery
Data[1] has shown that internet hits have surged by over 50% during the pandemic outbreak as over one-quarter of the world’s population has been locked down. Of course, the time people spend on online surfing will ease back after economic recovery, but it reminds us of the importance of brand digitization especially for the non-E-commerce business because you have no idea when the next “COVID-19” crisis will come. Reorganize and optimize the content through the online channels to keep your customers with you whenever, for example, through your website, your social media platforms and your email. Always pay more attention to the direct or indirect online communication with customers because it costs much less, covers more and is flexible beyond the geographical barriers.


2. Exploit new ways to present your business
As the quarantine policy keep people’s feet at home, it’s a good idea to rethink your business presentation. Even for the same old stuff, you can present in a brand-new way. For example, you can digitalize your factory tour and embed the VR visit on your website so that your customers can have panoramic one-the-site viewing experience whenever and wherever. Online exhibitions and webinars are becoming the choice of more and more companies to make up for the deficiency of unavailable physical attendance under the background of global pandemic outbreak. You can even live stream to interact with audience and sell your goods directly as customers accessing the Internet becomes much easier than ever before.

 
InfoComm, the largest professional audiovisual trade show in North America, is going virtual for the first time on June 16-18 in 2020.


3. Intelligentize your customer service system
You may have the experience that you call or online chat with the customer service but get late or no replies. When customer service team members are working at home, it increases the difficulty for them to respond to customers online or offline quickly. Hence, intelligentize your customer service system is a good choice. Automate the reply of your customer service, or even apply big data and AI technologies to learn how to further understand the needs of your clients, decreasing the cost of manual customer support and improving efficiency.   


4. Have more efficient video conference
In 2020 more and more office staff are forced or recommended to work at home. The transformation of workplace is asking higher requirement for more efficient online communication. You are sending more and more emails. You are joining more and more Zoom meetings. You need to catch up with more meeting-friendly tools to improve the video conference experience with your clients.
