In the last decade, flat panel displays have come a long way. Manufacturers are struggling to create next-generation technologies that have clearer images and faster response times. Micro LED technology followed the rise of OLED. But what this article is about is the latest improvement samsung has brought to its qlED display — by introducing self-illuminating technology for a longer life.

The QLED display technology currently available to Samsung for its own TV is still based on a combination of LED backlighting and quantum dot display panels. The film emits more solid colors than conventional LEDs, but the quantum dots themselves do not glow.
In contrast, the OLED pixels themselves glow, so they can turn off a single pixel instead of the entire illuminated area. The good news is that QLED is also expected to introduce this feature, according to a paper published by Samsung.
The team, led by Dr. Eunjoo Jang and Yo-Ho Won, has found ways to make an improved and more environmentally friendly self-illuminating QLED.
Previously, the impressive QLED display used cadmium elemental materials that were harmful to humans. In the future, however, Samsung will take full advantage of QLED manufacturing technology based on phosphate formulations. Although the performance is not very good, but more environmentally friendly.
It is reported that the research team by building around it to prevent oxidation of the shell and shorten the shell to improve the structure of the phosphate diode. Experiments demonstrated a 21.% increase in efficiency and an increase in diode life by 1 million hours.
If this new self-illuminating QLED technology is commercially available, consumers can enjoy a bright, animated, but more responsive alternative to OLED. Unfortunately, Samsung did not comment on QLED’s future course.
