A range of large LG TVsĪfter the industry's odd foray with 3D, it's good to see that display and TV makers are back to focusing on image quality, color reproduction, and resolution. Pricing on LG's 8K TV is unknown - but its 4K TVs, which went on sale this year, are surprisingly cheap. LG will reportedly start selling an 8K TV sometime this year - meanwhile, despite a year's head start, Sharp and Samsung don't yet have an 8K TV on the market.

55 inches is definitely on the large side, but I suspect it's just the right size for enthusiasts who want to enjoy movies or sports (or PC games?) at extremely high resolutions. While we saw some 8K TVs at CES 2014 from Sharp and Samsung, they were much too large for a normal home (85 inches and 98 inches respectively). With a resolution of 7680x4320, the TV touts around 33.2 million pixels - or 16 times the pixel count of your 1920x1080 TV. Read: No, TV makers, 4K and UHD are not the same thingĪnd then there's that 55-inch 8K TV. If the quantum dots help produce a whiter light, or a specific frequency of white that plays very well with LG's IPS LCD tech, then that could explain why this new 4K monitor has such exceptional color reproduction. LG doesn't say exactly how the quantum dots achieve this, but we do know from previous testing that the overall quality of a display is significantly affected by the quality of the light produced by the backlight (and the various other films and waveguides that sit between the backlight and the display).
In the case of LG, a film of quantum dots is placed in front of the backlight and behind the display, resulting in "picture color reproduction rate and overall brightness are significantly improved." Quantum dots, depending on their size, emit light at different frequencies Depending on the size of the dot, and also the material, you can tune these dots to emit very specific frequencies (colors) of light.
In short, quantum dots are just small specks of semiconducting material that emit light when they're excited. Quantum dots, despite sounding thoroughly futuristic, are actually fairly simple things that are easy to mass-produce. The 8K display is also notable because it's small - with a diagonal of 55 inches, this thing not only has an incredibly high resolution for a TV (160 PPI), but it will actually fit in most households, unlike the 85- and 98-inch 8K TVs that we've seen previously. In both cases, we are talking about IPS LCD panels, rather than OLED technology, which should mean that both the 4K and 8K displays are reasonably priced. At CES 2015 - now less than a month away! - LG says it will show off a 55-inch 8K TV, and a 4K TV that uses quantum dots to improve image quality and color saturation.
