Each year, SID awards its Distinguished Paper designation to the top 5% of more than 500 papers submitted by global display researchers demonstrating exceptional achievements.
An LG Display research team was selected for a Distinguished Paper award in recognition of their breakthrough achievements in developing fourth-generation OLED panel technology, which significantly improves performance compared to previous OLED generations in terms of brightness, color expression, and energy efficiency.
Fourth-generation OLED is based on LG Display’s proprietary Primary RGB Tandem technology, which stacks the three primary colors of light - red, green and blue - in separate, independent layers. This enables fourth-generation OLED to achieve a maximum brightness of 4,000 nits - the highest level in the industry (1 nit equals the brightness of a single candle).
In addition to increased peak brightness, fourth-generation OLED features improved color brightness, which allows enhanced color expression. Its color brightness of 2,100 nits is a 40% improvement over the previous generation. It also maximizes energy efficiency, meeting the increased power consumption demands of AI TVs with approximately 20% greater energy efficiency (based on a 65-inch panel).
The company presented its Distinguished Paper as well as 16 additional research papers on next-generation display technologies at SID Display Week 2025. In particular, it introduced research achievements related to a 480Hz OLED panel that applies its Dynamic Frequency & Resolution (DFR) technology.
LG Display’s proprietary DFR technology enables users to prioritize between a higher refresh rate or higher resolution depending on the content. Fast-paced games such as first-person shooter or racing titles can be enjoyed smoothly without any stuttering in high refresh rate mode (FHD∙480Hz). Movies or similar content can be experienced with an overwhelming sense of immersion in high resolution mode (UHD∙240Hz).
Meanwhile, the company’s 83-inch fourth-generation OLED TV panel won a People’s Choice Award at SID Display Week 2025. The award recognizes outstanding exhibits based on votes from visitors during the exhibition period.
Based on LG Display’s proprietary Primary RGB Tandem technology, the 83-inch fourth-generation OLED TV panel won a People’s Choice Award in the category of “Best OLED Technology.” It perfectly implements AI TV features such as upscaling, converting low-resolution content into exceptionally high picture quality. In addition, the panel’s reflectance was improved from 0.9% to 0.6% compared to the previous generation, enabling perfect black expression in any environment whether dark or bright.
