Introduction
Samsung’s QD‑OLED panels are among the best on the market, competing with LG’s WOLED across TVs and monitors. While LG uses a conventional white base layer with color filters, Samsung employs quantum dots with a blue base layer, enabling an additive process that enhances color volume. Historically, Samsung used a 4‑stack layer to achieve this, but it moved to a 5‑layer structure last year, now officially dubbed Penta Tandem.
Penta Tandem Technology
The term tandem refers to the method of stacking multiple OLED layers atop each other—a technique previously associated with LG (e.g., Tandem WOLED and Tandem OLED). Tandem approaches improve overall performance, typically boosting both brightness and longevity.
Samsung’s Penta Tandem denotes its shift to a 5‑layer stack. According to the press release, this architecture delivers:
- 1.3× higher luminous efficiency
- Doubling of panel lifespan
The increased efficiency allows the display to achieve higher brightness without extra power consumption or accelerated pixel wear. Penta Tandem TVs can reach up to 4,500 nits of peak brightness, while monitors are limited to 1,300 nits—still an improvement over the previous 1,000‑nit barrier. These monitors also support HDR True Black 500.

Products Featuring Penta Tandem
- Asus PG27UCDM – 27‑inch 4K 240 Hz QD‑OLED monitor powered by Samsung’s 4th‑Gen QD‑OLED panel.
- MSI 27‑inch 4K QD‑OLED monitor – Advertised with the “5‑Layer Tandem OLED” as part of the EL 3.0 materials upgrade.
- 31.5‑inch 4K and 34‑inch ultrawide (3440 × 1440) panels – Unveiled at CES 2026, both part of the Penta Tandem family.
- Upcoming 49‑inch dual QHD (5120 × 1440) panel – Listed by Samsung as the next model to receive the Penta Tandem update (refresh rate and sub‑pixel layout details pending).
Samsung also offers 27‑inch 1440p panels with 500 Hz refresh rates, which may receive the Penta Tandem upgrade in the future.
Future Outlook
Samsung plans to refresh existing panel classes with Penta Tandem technology throughout 2026. While the company has not confirmed whether the refreshed displays will adopt the new V‑stripe sub‑pixel layout, the move suggests a continued focus on higher brightness, longer lifespan, and improved text clarity across both TV and monitor segments.
