Samsung Display has begun mass production of the world’s first 34-inch 360 Hz QD-OLED panel featuring a V-Stripe RGB pixel structure. The company announced this development earlier this month. The V-Stripe design orients subpixels vertically, which improves text edge clarity. Samsung Display states this makes the panels suitable for text-intensive tasks such as document editing, coding, and content creation.
Samsung Display started supplying these panels to seven global monitor manufacturers, including ASUS, MSI, and Gigabyte, in December 2025. ASUS markets the ROG Swift OLED PG27UCWM, ROG Swift OLED PG34WCDN, and ROG Strix OLED XG34WCDMS as Stripe-RGB monitors. MSI promotes the MEG X and MPG 341CQR QD-OLED X36 as Stripe-RGB models.
LG Display announced last month that it will debut the world’s first 27-inch 4K OLED monitor panel with an RGB stripe structure and 240 Hz refresh rate at CES in Las Vegas. The company previously used WOLED technology with an extra white subpixel or triangular RGB pixel arrangements in its TVs and gaming monitors. LG Display says the new RGB stripe panels are optimized for operating systems such as Windows and font-rendering engines. They provide excellent text readability and high color accuracy, along with optimal performance in FPS games.
The advancements address text clarity issues, particularly in ultrawide OLED panels. Both LG Display and Samsung Display have shifted from structures like Pentile OLED to vertical RGB stripes for crisper images and easier-to-read text in new OLED gaming monitors launching this year.
LG Display also showcased Primary RGB Tandem 2.0 technology at CES. This advanced version of its proprietary Primary RGB Tandem stacks the three primary colors—red, green, and blue—in independent layers to generate light. The technology aims to increase OLED panel brightness significantly. Samsung Display uses quantum dots in its QD-OLED panels for similar brightness gains, while LG Display relies on these stacked layers.
LG Display promises that Primary RGB Tandem 2.0 will enable monitor displays to reach a peak brightness of up to 1,500 nits. For OLED TVs using the technology, peak brightness can reach up to 4,500 nits. The 1.0 version appeared in the LG G5 TV. ASUS states its PG27UCWM combines an RGB stripe panel with Tandem OLED technology, though it remains unclear if it employs the 2.0 version.
ASUS and MSI highlight Stripe-RGB technology in their upcoming monitors to deliver clearer and crisper visuals, resolving longstanding readability concerns in OLED gaming displays.
