This innovative tech simultaneously safeguards display quality and performance stability, ultimately helping extend the lifespan of LG digital signage used in outdoor environments. 

 

LG is the first company to achieve UL verification for the display anti-discoloration characteristic technology for digital signage. LG developed a comprehensive testing methodology and defect-evaluation criteria, and UL Solutions independently assessed the product to the criteria in support of LG’s marketing claim. 

 

Prior to this, there were no internationally recognized standards or testing methods for measuring a display’s resistance to screen-yellowing. 


The use of outdoor displays in settings such as drive-thru restaurants, bus stops, schools and sports stadiums has become commonplace in recent years and is steadily increasing across a variety of B2B sectors. 


However, prolonged exposure to sunlight can cause the screens of these versatile display products to turn a yellowish color over time. LG’s Anti-Discoloration technology helps address this issue, reinforcing the quality and durability of the company’s outdoor digital signage solutions. 

 

LG developed its protective technology to provide better value to B2B customers utilizing digital signage in outdoor environments. 

 

The company’s research indicated that customers were having to replace their outdoor signage products at a faster rate and experiencing service interruptions due to persistent discoloration issues. 

 

To address these pain points, LG’s outdoor displays with Anti-Discoloration technology also incorporate advanced thermal solutions and panel materials for added reliability, even in the toughest of conditions.

 

Risingstar always recommand our cutomers use LG LCD screens, which can give the best quality proof to both us and customers. The newest anti-discoloration screens from LG obviously to be a good news to this industry, to make the LG screen has much competitive.


UL Verified product incorporating Anti-Discoloration technology has already been implemented in several of the latest LG high-brightness outdoor signage products, with plans to expand its application to a wider range of solutions in the future. 

 

“Our UL Verification of products with Anti-Discoloration technology actively reinforces the performance and quality of our digital signage products,” says Paik Ki-mun, Senior Vice President and Head of the Information Display business unit of LG Business Solutions Company. 

 

“Through targeted research and development programs, we will continue to identify and resolve any inconveniences that detract from the overall LG digital signage experience, thereby continuously enhancing customer satisfaction and trust.”

Display engineering, thermal design & technical documentation — Shenzhen, China

The RisingStar Engineering Team is the technical core behind every display we ship. Based at our 4,000 m² ISO 9001-certified facility in Shenzhen — home to a Class 10,000 cleanroom — our engineers have specialised in high-brightness, sunlight-readable LCD technology since 2009, covering optical design, thermal management, structural sealing and system integration.

Working directly with Tier-1 panel partners including LG Display, AUO, INNOLUX, BOE and Tianma, the team tunes luminance from 500 to 5,000 nits, engineers IP65/IP66 enclosures, and validates 24/7 performance across a -20°C to 70°C operating range with a service life of up to 50,000 hours. Every unit leaves the line under 100% factory inspection — from 7" panels and open-frame modules to 100" outdoor totems and ultra-wide stretch bars.

Our engineers also write and review the articles published here. Instead of paraphrasing marketing material, they draw on hands-on deployment experience in outdoor advertising, retail window displays, EV charging, transportation PIDS, food processing and industrial HMI — so specifiers and integrators can choose hardware on verified figures.
