LG Gets Innovative Again, with upcoming Quantum Dot 4K TV and an 8K 55 inch Television
by Stephan Jukic – December 16, 2014
LG, the same innovator who brought the first (and so far only) OLED 4K TVs to market in late 2014, is now pushing TV display technology for the market further still with the upcoming unveiling of two new highly interesting products.
Both are going to apparently be revealed at the CES 2015 conference in Las Vegas, Nevada this January and the first of these is a new 4K television that uses quantum dots to improve image quality and color instead of the much more expensive OLED system. The second item is a new 55 inch 8K TV that will actually be going on sale in 2015.
In the case of both new TV types, LG will be using IPS LCD panels instead of OLED display technology. This could mean two things: First, that both TVs will be relatively reasonably priced despite their highly advanced new technologies and second, that LG itself is now moving temporarily away from OLED once again despite the releases of its 4K TVs with the display technology in this year. Given the prices at which the company’s existing OLED sets are selling ($3,500 for just the 55 inch model) it’s not farfetched to assume that LG has decided to shelve new OLED developments for the time being.
In any case, the 8K TV is particularly interesting in that it features a relatively small 55 inch display. This is in sharp contrast to previous prototype 8K models that all seem to hover around the 85 to 100 inch size range and are thus too huge for anything but a very large, spacious living room.
Furthermore, at 55 inches and with a whopping 33 million pixels that comes with 8K resolution, this new TV is going to have one absolutely spectacular resolution given its 160 ppi density. That’s close to the kind of pixel density you more often see on the high end 2K and retina screens found in the latest smart phone models! 8K means a total resolution of 7680 x 4320 pixels, so you can imagine the leap upward this represents from “conventional” 4K resolutions.
However, given the still notable lack of truly diverse 4K content and the still common problem of actually delivering the heavy data load of 4K video to any 4K TV, the difficulties that 8K will represent are heavy indeed. More than anything, the new 8K model is going to be a novelty item instead of a practical enhancement in resolution, even if LG actually starts selling it in 2015 as is being rumored.
As for the Quantum dot TV, despite the seemingly futuristic name of the technology, what it represents is something that’s not only quite simple but also fairly easy to produce, which is probably why Samsung is interested in them too. The dots consist of tiny particles of semiconducting material which emit light when they get excited. By introducing a film of these dots between a TVs backlight and display screen, the company claims that they can considerably improve image color reproduction and overall brightness.
Whether they really create an improvement that’s comparable to OLED display is something that we’ll have to see at CES 2015.
