LG Electronics Verifies World's First Screen Color Change Technology... Applied to Signage B2B New Products

World's First UL Certification for High-Brightness Signage Yellowing
Development of Anti-Discoloration Technology... Establishing Measurement Basis

LG Electronics' high-brightness signage has become the first in the world to receive verification from a global testing organization for minimizing screen discoloration. Brightness refers to the luminance per unit area.

On the 1st, LG Electronics announced that it recently received verification from global testing and certification organization UL Solutions confirming that LG signage has strong resistance to yellowing.

This is the first time among global manufacturers to obtain verification for display discoloration resistance. LG Electronics explained that it is significant not only because it developed technology to minimize yellowing but also because it was the first in the electronics industry to propose testing methods and discoloration judgment criteria and receive verification.

Yellowing is a phenomenon where the display screen turns yellow. High-brightness signage used in drive-thru store outdoor menus, signboards, bus advertisements, stadiums, and schools is more prone to this phenomenon when exposed to sunlight for extended periods.

LG Electronics focused on the fact that B2B customers experience frequent product replacements and service interruptions due to chronic yellowing issues. They conducted research and development (R&D) to identify the scientific causes of the problem, improve signage heat dissipation technology, and apply materials resistant to sunlight. As a result, they developed the 'Anti-Discoloration' technology that minimizes discoloration.

Previously, there were no clear testing standards to judge displays resistant to discoloration, making it difficult to quantitatively measure signage performance. LG Electronics collaborated with the Korea Research Institute of Chemical Technology to establish testing methods and defect judgment criteria to provide objective and scientific grounds. They secured credibility through UL verification.

LG Electronics plans to apply the Anti-Discoloration technology to new outdoor high-brightness signage products and gradually expand the range of applicable products in the future.

According to market research firm MarketsandMarkets, the global digital signage market is expected to grow from approximately $20.1 billion (about 28 trillion KRW) this year to about $27.3 billion (about 38 trillion KRW) by 2029, with an annual growth rate of over 6%.

Baek Gi-moon, head of LG Electronics' ID Business Division, said, "Through this verification, we have once again confirmed the highest level of signage quality and product technology. We will enhance customer satisfaction and trust through various R&D activities that identify and resolve customer inconveniences."
