"OLED is a dead-end; QLED is the future'
Samsung opts for smarter smart TV experience
Samsung has powered-up its Smart TV experience with a 'One Remote' control and an upgraded voice recognition feature that will allow consumers to use smart features more smartly, says its development team.
Like the insatiable desire for faster connectivity and more storage, the desire for lifelike TV images will never change. Samsung's introduction of quantum dot (QD) LCD TVs in 2015 -- branded SUHD then but now QLED -- was a statement of where the future lay, said Changbae Park, senior manager at product strategy team of the VD business.
Just a few years ago, the South Korean tech giant was heavily promoting OLED (organic light-emitting diode), butting heads with compatriot LG Electronics. It seemed OLED would be the next fight between the Koreans in their half-century-long rivalry in TVs.
Until Samsung introduced QD LCD TVs, that is. Put simply, a QD film is layered on the LCD that enhances the colour accuracy and range. Samsung began researching the core technology of QD materials 10 years ago with display applications in mind. But while Sony gave up on QD LCD in 2013 due to the need to use cadmium, which is harmful to humans, Samsung managed to overcome this. (Sony also gave up on OLED in 2010 after being the first to introduce an OLED TV in 2007.)
"We concluded that OLED was a dead-end," said Park. "There were a lot of fundamental problems with OLED, such as the burn-in, especially for over 65-inch large size TVs, which is difficult to overcome, and a limited brightness that's inadequate for HDR (high dynamic range).
"The choice was neither easy nor difficult. It was just an inevitable, logical choice on our part, if you consider what the consumers would want," the senior manager said. "I can categorically say that we do not plan to shift back to OLED. As a leader, it is not a responsible choice. Not now or in the future."
OLED uses organic materials that fundamentally limit the display's lifespan and causes burn-in, Park said. "Ask any retailers about burn-ins, and they will know."
Conversely, QLED uses inorganic materials that are more stable, meaning it doesn't have this problem. "We believe, ultimately, that the so-called OLED camp will, in the end, move towards QLED, and follow our lead," Park added.
The latest curved QLED TV. Flat-panel display technology has done wonders for TV designs.
"Internally, we have a roadmap. I don't want to say when, but we are heading towards an even more sophisticated technology with self-light-emitting quantum-dot diode. It will most likely be faster than people think it will be." Backlight will be removed and the QD material will emit light on its own.
