With QD-OLED, Samsung will correct OLED technology’s biggest flaw

Samsung is launching new technology for the television market. With its QD-OLED panels, the Korean company intends to erase one of the biggest flaws of OLED panels: brightness.

Samsung took advantage of the big mass at CES 2022 to unveil a new technology for the television market: QD-OLED panels. Under this still very complicated name hides a real evolution of OLED panels, supplied today by LG – Samsung’s big competitor. In a press release published on January 10, the Korean firm, via the Display branch, is pleased to have received certification from the independent body SGS, which allows it to formalize the contributions of QD-OLED.

It must be remembered that Samsung has already marketed OLED TVs, but very quickly turned away from technology to focus on le QLED (Improved LCD). The reason is simple: the company criticizes OLED for not offering sufficient brightness to satisfy its customers. A point that the QD-OLED would aim to greatly improve.

OLED versus QD-OLED

OLED and QD-OLED come together on one point: both technologies rely on pixels capable of emitting their own light. As a result, you get endless contrasts and truly black blacks – since individual pixels can go out completely, where LCD panels have to rely on less polished backlighting.

However, they differ in their way of broadcasting an image:

  • OLED panels (designed by LG) rely on white light at the source which will pass through RGB filters (red, green, blue) to produce different colors, filters which, unfortunately, reduce the light power;
  • QD-OLED panels (designed by Samsung) rely on blue light at the source which passes through nanoparticles (the famous QD, for Quantum Dots or quantum dots) in order to produce different colors, without losing light power (since ‘there are no more filters).

What is better light used for? Better brightness improves visibility in a lighted space and contributes to a better HDR show.

According to figures provided by FlatpanelsHD on January 5, QD-OLED panels are likely to achieve a light output of 1,500 nits – unheard of on OLED – and cover 90% of the Rec. color space. 2020 (compared to around 75% for LG tiles marketed in 2021). Thus, by using Quantum Dots, QD-OLED panels offer more accurate colors – hence better color space coverage. This is one of the great strengths of Samsung’s QLED televisions, which also rely on quantum dots.

Comparison of the light power between a QD-OLED panel and an OLED panel (LG model G1, tested by Rtings) :

QD OLED OLED (2021)
100% of the screen 200 nits 167 nits
10% of the screen 1 000 nits 827 nits
2% of the screen 1 500 nits 846 nits

Note that this comparison is based on LG panels marketed last year. It remains to be seen how will materialize small changes to the 2022 references (without change of structure, they will only be minor).

Despite all the benefits mentioned, Samsung has yet to unveil its own QD-OLED TV, a pioneer status reserved for Sony’s Bravia XR A95K. Alienware is also using a QD-OLED panel for its new PC monitor.
