LG Display presents OLED innovation and future display vision at “K-Display 2025.”
LG Display participated in ‘K-Display 2025’ held at COEX in Seoul for three days starting on the 7th, and unveiled a wide range of innovative display technologies and products covering large, small, and automotive displays. The theme of this exhibition is ‘Shaping the Future’, and OLED innovations and various display solutions that connect the present and the future were showcased. In addition, a space where visitors can experience the world’s first and highest-spec technology was created to enhance their understanding. LG Display organized the ‘OLED Heritage’ exhibition space so that the technological development process since the world’s first successful mass production of large-size OLEDs can be seen at a glance. Starting with the 15-inch OLED prototype in 2009, the development stages were intuitively introduced through models, starting with the tandem OLED two-layer structure, the second-generation OLED using the deuterium atomic structure, the third-generation OLED using micro lens array (MLA) technology, and the fourth-generation OLED using the primary RGB tandem structure, which stacks the three primary colors of light in independent layers. At the booth entrance, an 83-inch OLED panel utilizing 4th-generation OLED technology greeted visitors. This panel, an industry first, utilizes Primary RGB Tandem technology, which independently layers each RGB color, achieving a maximum brightness of 4,000 nits. A large-scale panel comparison demonstration showcased its outstanding color reproducibility and three-dimensionality.

The 27-inch QHD OLED monitor panel aimed at the gaming market can implement up to 720Hz (HD) with DFR (Dynamic Frequency & Resolution) technology, and boasts the highest level of picture quality among OLED monitors with DCI-P3 99.5% color reproducibility and maximum brightness of 1,500 nits. A 45-inch 5K2K OLED panel, which provides the highest resolution among existing OLED monitors, was also on display, allowing visitors to experience its performance while playing games. In the field of automotive displays, the SDV (Software-Driven Vehicle) concept car targeting the era of fully autonomous driving was exhibited. This vehicle is equipped with the largest 57-inch pillar-to-pillar LCD to date, which provides integrated driver information and entertainment on a curved screen that runs across the dashboard. A variety of automotive solutions were also unveiled, including a 32.6-inch slider OLED, a 29-inch ultra-high-brightness outdoor LCD, and a 47.8-inch LTPS LCD with SPM (Switchable Privacy Mode) technology that hides the passenger screen from the driver’s seat.

Another notable example was the application of the world’s first stretchable display, capable of expanding by up to 53%, to a vehicle jog dial. The display remains flat under normal conditions, but expands into a dial-like shape when a button is pressed.

Low-power solutions targeting the AI era were also introduced. The 14-inch tandem ATO panel achieves both high brightness and low power consumption by applying a tandem structure and a single glass substrate, and the 14.5-inch LCD maximizes battery efficiency with oxide TFT and low-power backlight technology, providing optimized performance for AI devices with increasing power demands. An LG Display official emphasized that the technological evolution of OLED is changing the paradigm of the display industry, and that the company will secure sustainable competitiveness and provide differentiated customer value by strengthening its future technology research and development capabilities as well as commercial technology perfection.
