Samsung Display Unveils Next-Generation Inorganic Light-Emitting Technology
Selected as SID's "Outstanding Paper of the Year"
LG Display Showcases Fourth-Generation OLED Panel
Samsung Display and LG Display are participating in 'Display Week 2025 (SID 2025)', which opens in San Jose, USA, starting on the 13th (local time). Each company demonstrated its technological prowess by unveiling next-generation technologies such as inorganic light-emitting technology and fourth-generation organic light-emitting diode (OLED) panels.
On this day, Samsung Display announced its participation in the SID 2025 exhibition, held from the 13th to the 15th at the McEnery Convention Center in San Jose, USA. This event brings together display companies and experts from around the world to share cutting-edge technologies and research and development (R&D) achievements.
At this exhibition, Samsung Display unveiled, for the first time, a 400-nit high-brightness electroluminescent quantum dot (EL-QD) display, which is 50% brighter than existing products, as well as a 264 PPI high-resolution product. EL-QD is a next-generation inorganic light-emitting technology that directly illuminates RGB (red, green, blue) pixels with an electric signal, without OLED, thereby improving color accuracy and reducing power consumption. The related paper was selected as SID's 'Outstanding Paper of the Year'.

In addition, Samsung Display exhibited a sensor organic light-emitting diode (OLED) display that can detect fingerprints and health information across the entire screen. By depositing an organic photodiode (OPD) onto the panel, this technology can measure heart rate, blood pressure, and atrial fibrillation. It was also introduced earlier this year in the international journal 'Nature Communications'.
Among RGB OLEDoS products, Samsung Display also unveiled, for the first time, a product with industry-leading resolution of 5000 PPI. The display is just 1.4 inches in size?small enough for a smartwatch screen?but offers higher resolution than an 8K TV. This product achieves up to 15,000 nits of brightness and a 120Hz refresh rate, making it a high-performance component for extended reality (XR) devices.
Additionally, an RGB OLEDoS display with 20,000 nits of brightness was unveiled for the first time. Other future form factor products were also showcased, including a previously announced microLED-based stretchable display, a 'flexible briefcase' that folds into the shape of a bag, and the 'Polygon Foldable', a diamond-shaped foldable phone.
Lee Changhee, Head of Display Research Center (Executive Vice President), said, "We are pleased to showcase Samsung Display's overwhelming technological capabilities at an event attended by leading scholars and experts from around the world," adding, "We will continue to actively communicate with academia and the market, and will be the first to introduce solutions that customers want, thereby leading technological change."

LG Display showcased next-generation display technologies, including its fourth-generation organic light-emitting diode (OLED) panel. The fourth-generation OLED panel unveiled at this exhibition achieved up to 4,000 nits of brightness by applying a 'primary RGB tandem' structure. This is LG Display's proprietary technology of stacking RGB elements independently. Based on this, the company plans to expand its premium product lineup, including AI TVs and gaming OLEDs.
LG Display also unveiled the '45-inch 5K2K Gaming OLED', which achieves a world-class resolution of 5120x2160. With approximately 11 million pixels densely packed into the 45-inch large screen, it delivers outstanding picture quality and adopts a cinematic screen ratio of 21:9 for enhanced immersion.
LG Display also introduced its proprietary DFR (Dynamic Frequency and Resolution) technology, which allows users to select refresh rate and resolution according to content. This provides a high refresh rate mode for gaming and a high-resolution mode for movie viewing, delivering a customized user experience.
In the automotive display zone, LG Display exhibited a concept car equipped with a stretchable display, a 57-inch pillar-to-pillar (P2P) display, and an 18-inch slidable OLED. In particular, the slidable OLED is designed to be rolled into the ceiling, maximizing space utilization inside the vehicle, and it is durable enough to operate from -40 to 85 degrees Celsius.
LG Display also presented sustainable display technologies. The 'Neo LED' panel improves battery efficiency with low power consumption, while the '14-inch eco-friendly notebook panel' is made with 41% recycled materials by weight, enhancing its environmental friendliness.
Yoon Sooyoung, Chief Technology Officer (CTO) of LG Display, stated, "We will continue to create differentiated customer value and further strengthen our technology leadership in the future display market." LG Display plans to present 16 advanced research papers at this event, including research results on the fourth-generation OLED.
