LG Display announced on the 18th that its research paper on the new technology for its fourth-generation OLED panel has been selected as a 'Distinguished Paper' at the Society for Information Display (SID), the world's most prestigious display conference.
SID designates the top 5% of papers that achieve outstanding results among more than 500 papers submitted annually by display researchers worldwide as distinguished papers. The LG Display research team was selected for the distinguished paper by introducing research results on the fourth-generation OLED panel that significantly enhances performance in terms of brightness, color expression, and energy efficiency.
The fourth-generation OLED panel applies a unique technology called 'Primary RGB Tandem,' which stacks the primary colors of light—red (R), green (G), and blue (B)—in independent layers. This has achieved an industry-leading maximum brightness of 4,000 nits (nit, with 1 nit equivalent to the brightness of one candle).
By increasing the maximum brightness and enhancing color expression, the panel also succeeded in achieving a 40% improvement in color brightness, now capable of 2,100 nits, compared to the previous generation. Additionally, energy efficiency was maximized to improve by about 20% (based on a 65-inch model) to accommodate the greatly increased power consumption of AI TVs.
Meanwhile, LG Display presented 16 research papers in the next-generation display field, including this year's distinguished paper, at the SID 2025 event. Notably, it introduced the research result of its 480Hz OLED panel applying the unique technology DFR (Dynamic Frequency & Resolution).
This panel allows users to choose priority between refresh rate and resolution based on content, utilizing the DFR technology developed by LG Display, the world's first. Fast-paced games such as first-person shooter (FPS) or racing can be enjoyed smoothly in high-refresh-rate mode (FHD·480Hz), while watching movies can provide an overwhelming immersion in high-resolution mode (UHD·240Hz).
