Samsung R&D has announced that it has achieved industry-leading performance in blue QLED, bringing it one step closer to QLED displays.
If you are confused, it is understandable. Samsung is currently marketing its LCD TVs as "QLED TVs" based on a structure of a thin film of quantum dots between the LED backlight and the LCD panel.
In there future, however, we may get actual QLED displays, meaning quantum dot light-emitting diodes (LED) where each pixel generates its own light – like OLED and microLED. That is what Samsung Advanced Institute of Technology (SAIT), which is Samsung's R&D hub, is researching. And it is now reporting progress in the area.
- "... blue is known to be the most difficult color to implement out of the three primary QLED colors (red, blue and green)," said SAIT. "But now, SAIT has successfully developed blue QLED technology, achieving industry-leading results such as 20.2% improved luminous efficiency, 88,900 nits of maximum luminance and 16,000 hours of QLED lifetime (measured at half-brightness for 100-nit luminance)."
It means that a blue QLED now has 16,000 hours of lifetime (at 100 nits brightness) before brightness halves to 50 nits. Ideally, further progress would be needed, but these are industry-leading results (for nox-toxic, cadmium-free blue QLED), according to Samsung in a study titled "Efficient and stable blue quantum dot light-emitting diode".
To create a next-generation display, QLEDs in blue, red, and green would make up the three sub-pixels behind each pixel. The new display technology could potentially deliver more saturated colors than today's displays.

It is still too early to expect QLED displays in the short term and there is reportedly internal conflict within Samsung over the future direction. Samsung Display, the display manufacturer, is planning to mass-produce QD-OLED first and is willing to sell to Sony and Panasonic if Samsung Electronics refuses. Samsung Electronics, the consumer electronics maker, on the other hand is said to be pursuing microLED technology in the short term.
