South Korean display technology giant LG has officially announced the world’s first 240Hz OLED panel with RGB strip subpixel layout, making it one of the most important and exciting display reveals at CES 2026.
The 27-inch 4K OLED panel supports a peak refresh rate of 240 Hz. This makes it an excellent option for professional use cases such as high-end gaming or competitive esports, but is also attractive to developers and power users who rely on precise frame timing.
The RGB stripe structure greatly improves text clarity
However, this is not the main highlight of the panel. Unlike traditional OLED panels that use the company’s WRGB structure (which includes white subpixels), the new panel features an “RGB stripe structure.”
The RGB stripe structure arranges all red, green and blue subpixels in straight vertical lines (similar to LCD monitors). This reduces issues such as color bleeding, color fringing and visual distortion, even when viewed up close.
In theory, the RGB strip structure should also improve text clarity, a persistent weakness of traditional OLED monitors. In addition to text, you should expect improvements in sharpness, interface clarity, and overall desktop usability without sacrificing motion clarity.
LG has also increased the aperture ratio, the relative proportion of the pixel area that emits light, improving brightness efficiency without increasing power consumption. To put it simply, the panel should deliver higher peak brightness and better uniformity while maintaining the contrast of the OLED panel.
If you’ve been tempted by OLED monitors but held back because you spend hours reading, writing, programming, playing video games, or working with text-heavy interfaces, LG’s 27-inch 4K OLED panel with RGB stripe structure should provide an excellent experience.
The panel borrows its clarity from LCD panels, contrast and colors from OLEDs, and an ultra-fast refresh rate with a near-zero response time while offering 4K resolution (160ppi). The only thing we’re waiting for now is other brands adopting the technology (including LG Electronics) and announcing products at or after CES 2026.
