Displays Also Go Green... From Eco-Friendly Certification to Securing International Standards

LG Display Receives Eco-Friendly Certification for High-End LCD Panels for Automotive and IT Use
Samsung Display Contributes to Greenhouse Gas Emission Reduction through Low-Power OLED Technology

[Asia Economy Reporter Park Sun-mi] The display industry, which has focused its technological capabilities on larger and brighter screens, is recently intensifying efforts to obtain eco-friendly certifications. This is because as interest in eco-friendly products grows, more consumers are seeking products that consume less power and emit fewer harmful substances.

On the 14th, LG Display announced that more than half of the five eco-friendly certifications it received over the past three years for its display and manufacturing sites?three in total?were obtained in the second half of this year. The most recent certification was awarded this month to its automotive display P-OLED (Plastic OLED) and premium LTPS (Low-Temperature Polycrystalline Silicon) LCD panels by SGS, a global inspection and certification organization based in Switzerland, marking the industry's first 'Eco Product' certification. This certification is granted to eco-friendly products that comply with global environmental regulations throughout the entire process from production to use and disposal, minimizing the use of harmful substances. In particular, LG Display’s automotive P-OLED and premium LTPS LCD panels received high evaluations for both power consumption and reduction of harmful substances.

Last month, 27-inch and smaller high-end LCD panels for IT devices such as monitors, laptops, and tablets received the Eco Product certification from SGS. They were highly rated in terms of ▲recycling rate ▲reduction of harmful substances ▲resource efficiency ▲energy efficiency. LG Display’s domestic sites (Paju, Gumi) also received a Zero Waste to Landfill certification (with a recycling rate of over 90%) from UL Solutions, a U.S.-based eco-friendly certification company, in July this year. An LG Display official said, "We are exploring various ways to enhance the eco-friendliness of display panels, which are key components of IT devices," adding, "Obtaining eco-friendly certifications from credible external organizations allows customers to use eco-friendly products for promotional activities and can also help improve ESG (Environmental, Social, and Governance) external evaluation scores and facilitate the issuance of green bonds (bonds issued to raise funds for environmentally friendly projects)."

Samsung Display has developed a proprietary method to measure the power consumption of IT OLED panels and achieved IEC (International Electrotechnical Commission) international standard certification. As accurately measuring and labeling the actual power consumption of laptop displays has become increasingly important, this new measurement method considers real-use environments where screen brightness varies widely. Samsung Display explained that this OLED power consumption measurement standard is ready for immediate commercialization within the industry. The company expects the newly adopted power consumption measurement standard to bring more beneficial changes to the IT product selection process.

Samsung Display is also contributing to reducing greenhouse gas emissions through low-power OLED technologies such as Eco Square. Eco Square technology refers to Samsung Display’s developed ‘polarizer-free OLED panel’ technology. By developing a panel lamination structure that blocks external light reflection instead of using a polarizer, it increases light transmittance and can reduce panel power consumption by up to 25%. Panels using this technology allow users to enjoy movies and games on bright phone screens while extending battery life. Samsung Display applied this technology last year to the Galaxy Z Fold 3 and this year to the Galaxy Z Fold 4, and plans to expand its application to other smartphone models as well as IT products in the future.
