Samsung Claims Its New QLED TVs Are Better Than OLED TVs (theverge.com) 190

Posted by BeauHD from the he-said-she-said dept.
Samsung recently unveiled its latest flagship televisions at CES 2017, the QLED series. The company is challenging the notion that OLED TVs represent the pinnacle of picture quality in the living room. According to Samsung, the QLED TV represents its best achievement in image quality and viewing experience yet. The Verge reports: Of course Samsung would say that at an event meant to showcase said product. But the company insists it's made very real improvements compared to the flagship TVs it unveiled only a year ago. One of those upgrades pertains to brightness. The QLED TVs reach a peak brightness between 1,500 and 2,000 nits -- up from the 1,000 peak from 2016's lineup. Color reproduction has also been improved. The QLED sets handle DCI-P3 "accurately" and are capable of reproducing "100 percent color volume" -- something Samsung claims to be a world first. "This means they can express all colors at any level of brightness -- with even the subtlest differences visible at the QLED's peak luminance -- between 1,500 and 2,000 nits." Samsung says all of this is possible because it's using a new metal material along with the quantum dot nanocrystals. On the software end, Samsung's 2017 TVs are still powered by Tizen and feature basically the same user interface as last year. But there are some new additions like a sports mode that aggregates scores and other content from your favorite teams and an expanded Music section that lets you Shazam music as it's playing in a TV show and immediately launch that track in Spotify another streaming services. Samsung is also looking to clean up how its TVs look in your living room. New this year is a clear-colored "Invisible Connection cable" that runs from the TV to an external breakout box where you'll find all the HDMI ports and other critical connections (besides power, which is a separate input).

      The director has a properly calibrated high end display. To match that on your screen, it also needs to be calibrated and capable of displaying a wide colour gamut. But your environment is probably very different to the director's, likely much brighter. So the TV has to compensate with very high contrast levels.

                  You have 3 color receptors in your eyes, each of which has a bell curve [wikipedia.org] of responsiveness to frequency. These bell curves overlap, allowing you to tease out quite a bit of information about color from the strength of these 3 signals. Most colors we see are themselves bell curves of emitted frequency, because most light sources are.

                  You could fake all this exactly with 3 colors, if you could chose the specific 3 colors emitted on the fly for each pixel (three variables, three unknowns). But since you have t

    Maybe Samsung can claim and does have higher brightness (not sure if it's relevant since most people have their TVs at apartments/houses and usually watch them in the evening/at night) and a wider gamut, but when it comes to darkness/dim lights, OLEDs are miles better. I'd have deeper blacks over higher brightness/wider gamut any time, please.

    The claim is "they can express all colors at any level of brightness".

    Currently every shipping consumer television (inorganic LED or OLED) can only display the DCI-P3 [wikipedia.org] color primaries, making the entire color gamut a triangle substantially smaller than "all colors".

    Newer sets are able to receive color information in a container based on ITU-R Rec. 2020 [wikipedia.org] color primaries, however no sets can actually display the colors outside of DCI-P3 but inside ITU-R Rec. 2020. Moreover, even the gamut of Rec. 2020 is not "all colors."

    To have a container for all colors with three primaries, you have to have color primaries that are not realizable, such as the CIE 1931 XYZ [wikipedia.org] space or the ACES [wikipedia.org] color space.

    However no one has yet invented a display system that can display colors that are not realizable, because they are not realizable.

    No system can display "all colors" additively, unless you use a system with color primaries based on all of the monochromatic colors (i.e. much more than three primaries - thousands). Four or five color primaries added together can get close. Allowing subtraction as well as addition of color primaries can help, but that is difficult to realize.
