Dat laatste is een algemene naam voor de gebruikte schermtechniek.
Qled en Oled zijn natuurlijk twee verschillende technieken. Samsung heeft het alleen Q led genoemd zodat mensen de fout gaan maken dat ze denken dat het O led is.
Is wel bizar weinig informatie beschikbaar ook op de eigen website van
Hisense.
Wat de techniek Uled precies inhoudt staat er niet, of het een VA of een IPS paneel betreft staat er niet, of het HDR 10, HDR 10+, Dolby Vision heeft staat er ook niet behalve: 'hdr plus', wat dat ook moge zijn?
Verder staat er dat het de codec VP9 en HEVC ondersteund, helaas dus geen VP9.2 voor HDR weergave op bijv YouTube.

So what’s ULED then? Well unlike OLED it’s not actually a single technology. ULED, or Ultra LED, is the term Hisense uses for a collection of 20 different patents around four key areas: Ultra Wide Colour Gamut, Ultra Local Dimming, Ultra 4K Resolution and Ultra Smooth Motion Rate. As the name suggests, this is an LED TV technology, but those propriety patents all work to enhance the viewing experience at home.
Colour
ULED TVs have a wide palette and are capable of reproducing a really broad array of colours for images that look brighter and more detailed. Without getting into the heavy terminology or too many numbers, the current industry requirements for the Ultra HD Premium standard require a TV to be able to display 90 percent of the colours defined by something called the DCI-P3 — the Series 7 ULED TV can display 99.98 percent.
Dimming
As mentioned before, OLED achieves blacks by simply turning off pixels. ULED uses something called local dimming instead. The panel on the Hisense Series 7 is divided into many different zones, each of which can be dimmed and brightened independently of the others. This allows for a very good contrast range as well as great detail when it comes to shadows.
Resolution
All ULED TVs are 4K Ultra High-Definition when it comes to the screen resolution. That’s a resolution of 3,840 x 2,160 (sometimes called 2160p). That’s four times the number of pixels compared to a Full HD TV. With the right 4K content, this means a sharper and more detailed image than you’ve ever seen before. OLED doesn’t have a specific resolution tied to the technology — we’ve seen both 4K and Full HD OLED TVs recently.
Motion
ULED TVs all use a system called UltraSmooth Motion, which is basically a clever algorithm for the TV to create and insert frames into a video, making for smoother transitions. This gets paired with something called Backlight Scanning and the end result is that your fast action films don’t look blurry, and brighter objects can move through dark backgrounds without getting that distracting ‘halo’ effect.
This is just scratching the surface when it comes both OLED and ULED — there’s a lot of very smart, very high-tech wizardry that goes into both. But hopefully when you’re looking for your next TV, you’ll be armed with a little bit more knowledge when it comes to the fast-moving world of TV technology.
