LG Display said on the 23rd it will unveil the world's first 27-inch 4K OLED panel for monitors that achieves a 240Hz high refresh rate with an RGB (red, green, blue) stripe structure at CES 2026, the world's largest IT and home appliance show.
The RGB stripe structure arranges RGB subpixels—the three primary colors of light—side by side, reducing distortions such as color fringing even at close viewing distances. Panels with the conventional RGB stripe structure were limited to a maximum refresh rate of 60Hz, making them unsuitable for use as gaming monitors.
The 27-inch 4K OLED panel for monitors unveiled by LG Display raises the refresh rate to 240Hz for the first time while maintaining the RGB stripe structure. Based on the high refresh rate, it is expected to deliver optimal performance in titles such as FPS games that require rapid screen transitions. It is also optimized for operating systems and font engines such as monitor windows, offering high readability and color accuracy. With a high pixel density of 160 ppi (pixels per inch), it can render fine details.
LG Display applied its specialized DFR (variable refresh rate and resolution) technology so users can choose between high-resolution mode (UHD 240Hz) and high-refresh-rate mode (FHD 480Hz).
LG Display plans to introduce the new pixel structure first in high-end gaming monitor and professional monitor panels. It then plans to expand to more clients and product lineups. LG Display produces about 30% of the world's OLED panels for monitors and is targeting the high-end monitor market.
Lee Hyun-woo, head of the large business unit at LG Display, said, "To lead the fast-growing OLED monitor panel market, technological prowess is essential," and added, "We will further strengthen our leadership in the global market by focusing on technologies that differentiate us from competitors, technologies our clients want, and technologies with business viability."
