LG Display Becomes World's First to Verify Commercialization of Blue Phosphorescent OLED Panels

Final Step to Achieving "Dream OLED"

SEOUL, South Korea, May 1, 2025 /PRNewswire/ -- LG Display, the world's leading innovator of display technologies, announced today that it has become the world's first company to successfully verify the commercialization-level performance of blue phosphorescent OLED panels on a mass production line. The achievement comes about eight months after the company partnered with UDC to develop blue phosphorescence, and is considered a significant step closer to realizing a "dream OLED" display.

In the display industry, "dream OLED" refers to an OLED panel that achieves phosphorescence for all three primary colors of light (red, green, and blue). OLED panel light emission methods are broadly categorized into fluorescence and phosphorescence. Fluorescence is a simpler process in which materials emit light immediately upon receiving electrical energy, but its luminous efficiency is only 25%. In contrast, phosphorescence briefly stores received electrical energy before emitting light. Although it is technically more complex, this method offers luminous efficiency of 100% and uses a quarter as much power as fluorescence.

However, achieving blue phosphorescence has remained a major challenge even more than 20 years after the commercialization of red and green phosphorescence. This is due to blue, among the three primary colors, having the shortest wavelength and demanding the greatest energy.

LG Display has solved this issue by using a hybrid two-stack Tandem OLED structure, with blue fluorescence in the lower stack and blue phosphorescence in the upper stack. By combining the stability of fluorescence with the lower power consumption of phosphorescence, it consumes about 15% less power while maintaining a similar level of stability to existing OLED panels.

In particular, LG Display is the first to succeed in reaching the commercialization stage of blue phosphorescent OLED panels, where performance evaluation, optical characteristics, and processability on actual mass production lines should all be confirmed. The company has already completed commercialization verification with UDC.

LG Display has independently filed patents for its hybrid blue phosphorescent OLED technology in both South Korea and the United States.

The company will showcase a blue phosphorescent OLED panel featuring two-stack Tandem technology at SID Display Week 2025, the world's largest display event, in San Jose, California from May 11th (local time).

At the show, LG Display will be unveiling a blue phosphorescent OLED panel featuring two-stack Tandem technology applied to a small and medium-sized panel that can be applied to IT devices such as smartphones and tablets. As more and more products require high definition and high efficiency such as AI PCs and AR/VR devices, the application of blue phosphorescence technology is expected to expand rapidly.

"The successful commercialization of blue phosphorescence technology, which has been called the final piece of the 'dream OLED' puzzle, will become an innovative milestone towards the next generation of OLED," said Soo-young Yoon, CTO and Executive Vice President of LG Display. "We expect to secure a leading position in the future display market through blue phosphorescence technology."

LG Display Becomes World's First to Verify Commercialization of Blue Phosphorescent OLED Panels

LAS VEGAS, Jan. 9, 2026 /PRNewswire/ -- Guide Sensmart (Booth 21740, Central Hall), a global leader in thermal imaging technology, officially launched its next-generation thermal imaging innovation – ApexVision – alongside a series of new products empowered by the technology. This launch represents a systemic leap for the industry from merely "seeing heat" to "seeing with clarity, precision, and intelligence," marking the dawn of a new era defined by Ultra-Clarity.

CES Show Floor Reaction: "Ultra-Clarity" Draws Deep Engagement

At the Guide Sensmart booth, live product demonstrations powered by ApexVision attracted strong attention from industry analysts to global media. Hands-on comparisons—such as maintaining clear imaging details of distant targets and delivering crisp, smear-free imaging of fast-moving objects—earned consistent praise. Many professional visitors noted that this reliable "what-you-see-is-what-you-get" clarity would directly enhance operational efficiency and decision-making confidence.

ApexVision integrating both hardware and software: It combines the high-sensitivity ApexCore S1 detector, the Nexus 1.0 processing platform, and scenario-optimized algorithms. Together, ApexVision successfully overcomes persistent challenges such as low contrast in complex environments, detail loss at long range or high magnification, motion blur on fast-moving objects, and inaccurate detection of minute temperature differences.

From Architecture to Application: A Full Portfolio Empowered

On the CES show floor, Guide Sensmart demonstrated how ApexVision delivers tangible improvements across thermal devices. Thermography tools (e.g. E3S, H6S thermal cameras) leverage the SharpIR 2.0 algorithm to provide stable, accurate temperature measurement in demanding environments, enabling inspectors to pinpoint hidden faults with greater confidence. Outdoor hunting optics (e.g. TD650LS monocular and TN650MS binocular), benefit from Hyper-Light 2.0, allowing users to identify nocturnal wildlife in complete darkness and track fast-moving targets while maintaining clean, sharp images even at 10× zoom.

"The launch of ApexVision marks a milestone where our vertically integrated technology development translates into real value for users," said a Guide Sensmart spokesperson. "It is more than a set of specifications—it delivers the certainty of Ultra-Clarity to every professional user."

The debut of ApexVision at CES 2026 signifies more than a routine product update. By resolving long-standing trade-offs between sensitivity, stability, and environmental robustness, Guide Sensmart is advancing thermal imaging into the Ultra-Clarity Era, building a clearer, safer, and more efficient future.

We are keen to explore partnership of collaboration with you. Know more about Guide Sensmart at https://www.guideir.com.
