Samsung Mass-Produces 34-inch 360Hz V-Stripe QD-OLED

Samsung's QD-OLED technology has long competed with LG's WOLED, standing out with higher color volume. By combining blue light-emitting layers with quantum dots, Samsung transforms the traditional "subtractive" filtering method into an "additive" imaging process. However, this innovation previously came with a trade-off: unconventional subpixel arrangements in QD-OLED panels led to blurred text and noticeable color fringing.

At CES 2026, Samsung Display revealed a solution to this long-standing issue. The company has started mass production of the world's first 360Hz V-Stripe QD-OLED panel. This is a 34-inch ultra-wide panel with a 1800R curvature and a 360Hz refresh rate. For the first time in QD-OLED panels, Samsung has achieved peak brightness of 1300 nits, and monitors based on this panel will meet HDR True Black 500 certification, delivering 500-nit peak brightness even at full-screen coverage.

The V-Stripe design refers to vertically aligned red, green, and blue subpixels arranged side by side—similar to traditional LCD layouts and well-suited to Windows font rendering. For years, QD-OLED panels used triangular subpixel arrangements, which caused fuzzy text edges and pronounced fringing.

While the name "V-Stripe" can be misleading, it does not imply a V-shaped layout. According to TFT Central, the vertical alignment of subpixels forms column-like structures, with full pixels arranged horizontally. This simple adjustment significantly reduces text fringing and improves clarity, even at lower resolutions.

Samsung is not changing the fundamental physical structure of QD-OLED panels but aims to make subpixel spacing more uniform. Previously, manufacturers mitigated these issues by increasing pixel density—higher resolution panels reduce subpixel inconsistencies, but at the cost of higher production complexity.

A Samsung Display spokesperson commented: "By leveraging the brightness advantages of the QD-OLED top-emission structure, combined with improved organic material efficiency and design optimization, we have successfully mass-produced a high-performance panel featuring four key attributes: V-Stripe pixel layout, ultra-wide aspect ratio, high refresh rate, and higher peak brightness."
