According to a talk by a South Korean professor, reported by The Elec (opens in a new tab). Specifically. Samsung is developing a new kind of blue OLED pixel which could be the catalyst that the technology needs to start lower prices and compete directly with the standard (and less expensive) OLED panels used in the top OLED televisions available today.
The background is that Green and red OLED pixels are constructed of phosphorescent substances that offer 100% brightness internally. However, blue OLED pixels are made of fluorescent materials, providing only 25 percent effectiveness.
In contrast to traditional OLED screens that use red, blue, and green pixels to produce colors, QD-OLED screens utilize green and blue pixels (with the quantum dots which convert the light to different colors). The Elec states that at present QD-OLED screens use three blue pixels (because their effectiveness is restricted) and only one layer of green pixels.
Samsung Display’s study was to develop the phosphorescent blue pixel hoping to bring the blue’s efficiency up to the other colors. The company has already released the results of the research. However, according to Prof. Kwon Jang-hyuk from Kyung Hee University, Samsung ” prioritizes applying phosphorescent blue OLED material on its advanced TV panel,” The Elec reports. The Elec.
Professor Kwon stated that “Samsung Display likely had made a process on developing phosphorescent blue OLED material” in actual practice, not just in theory. He declared that Samsung plans to showcase something with the new technology “within the year.”
The advantage is that Samsung will not need to utilize four layers. It could reduce the number of layers to two: one layer of blue and one layer of Green. This would decrease both the material required and the complexity of making OLED panels. This will make them more efficient in producing and more efficient at producing luminescence.
More efficient production means less production. And with QD-OLED TVs currently ranked at the top of the market for 4K TVs, dropping prices is what they require to bring them to the mainstream.
Analyzing: A factual assertion, which could be required
In addition, as noted from The Elec, Samsung Display isn’t the only one focusing on developing viable OLED pixels that are phosphorescent. UDC is based in the US and has stated that it intends to launch the technology by 2024. If this is the case, it isn’t a stretch to think that Samsung Display would be able to do it at approximately the same time or perhaps a bit earlier.
The first QD-OLED TVs -are the Sony A95K and Samsung S95B and are extremely expensive. With some standard OLED TVs currently sold for less than $1,000 or PS1,000 or lower, QD-OLED seems to be a long way from competing with the price. However, as the cost of living continues to rise and the demand for high-end TVs may be squeezed, consumers opt to save money and buy the same TV better than the cost.
The faster Samsung Display can reduce the cost of producing QD-OLED displays, the better since it’s an exciting technology, and we’d be a bit disappointed to see it neglected. In between Samsung Display generally being able to boost the yield of its production (reducing cost) and the potential of this revolutionary technology, it appears that Samsung Display is set for an exciting future.
