Achieving Both Image Quality and Speed: LG Display Unveils 240Hz RGB Stripe OLED Panel

To Be Unveiled for the First Time at CES 2026

Reduced Distortion, High Refresh Rate Performance

LG Display has unveiled its next-generation OLED monitor panel, which enhances both image quality and screen refresh rate, as it sets out to target the high-end gaming and professional monitor markets.

On December 23, LG Display announced that it will introduce a 27-inch OLED monitor panel featuring 4K resolution and a high refresh rate of 240Hz to the global market at CES 2026, the world's largest information technology and consumer electronics exhibition.

This panel features an RGB stripe structure, in which red, green, and blue (RGB) subpixels are arranged in a straight line. This design minimizes color bleed and edge distortion even when viewed up close. While previous RGB stripe OLED panels offered excellent image quality, their refresh rates were limited to around 60Hz, which made them unsuitable for high-performance gaming monitors.

With this new product, LG Display has maintained the RGB stripe structure while increasing the refresh rate to 240Hz. In addition, dynamic refresh rate and resolution technology have been applied, allowing users to choose between ultra-high-definition mode (4K 240Hz) and ultra-high refresh rate mode (Full HD 480Hz) according to their needs.

Thanks to its high refresh rate, this product delivers optimal performance in first-person shooter (FPS) games and other scenarios requiring rapid screen transitions. It is also optimized for operating systems and font engines used in monitor windows, resulting in high readability and color accuracy. Furthermore, with a high pixel density of 160 ppi (pixels per inch), it offers detailed and precise image rendering.

Existing high-end gaming OLED monitor panels have typically used either an RGWB structure, which adds a white subpixel to the RGB array, or a triangle structure where RGB pixels are arranged in a triangular pattern. However, because these pixel structures were designed for LCD (liquid crystal display) environments, they often resulted in distortion due to recognition errors by operating systems. To address this, LG Display developed a new pattern optimized for monitor use and applied various new technologies, such as increasing the aperture ratio (the proportion of the pixel area that emits light). As a result, the company succeeded in achieving both the RGB stripe structure and a high refresh rate in a single panel.

An LG Display representative stated, "Demand for OLED monitor panels is increasing, but there have been limitations because operating systems and graphics processing systems are optimized for LCDs. Now, we have developed a pixel structure suitable for OLED monitor panels."
