Jan 9, 2017: With Samsung promoting QLED as the next popular TV technology, many companies have started considering it for their TV models. Samsung is reportly working on QLED TVs, and is investing resources into the technology, ignoring OLED technology altogether. It has showcased its QLED TV at CES 2017, and is expected to launch in the market in the next two to five years.
It is reported that LG is also researching QLED technology, and working with Nanoco, Nanosys and QD Vision on the technology.
However, industry experts say that QLED TVs will still take some time to be produced as the manufacturing technologies are still not in place, and the process still contains cadmium materials, which are extremely toxic.
Currently, QLED is being used for some entertainment and architectural lighting. But if Samsung and LG bring QLED TV sets in the market, then many other TV manufacturers will follow suit as the technology sound to be good.
How is the QLED technology?
QLED or quantum dot LED, delivers superior picture quality compared to LCD. QLED uses quantum dots in a new and interesting way.
When quantum dots—microscopic molecules—are hit by light, they emit their own colored light, and this color depends on their size. The larger molecules give off red light, and the smaller ones give of blue light.
While current TVs use photoluminescent quantum dots, QLED TVs will use electroluminescent quantum dots. Electroluminescent ones use electrons to generate light, instead of the light from an LED. This lets the TV light up and turn off individual pixels, just like an OLED TV.
While OLED TVs are still very expensive, quantum dot technology is more cost-effective than OLED. QLED screens also have about 30-40% more luminance efficiency, which makes pictures more brighter with more vivid colours. It will also cost less to manufacture QLED sets. QLED TVs also just half as much power as OLED TVs, making them cheaper to run as well.
