Hisense ULED XD is real TVs revolution
  • Hisense uses Dual-cell ULED XD panel layer that puts a 1080p module displaying a grayscale image between a full array LED backlight and a 4K module. Panel has 2,900 nits peak brightness.

    Also they have 512 direct led backlight zones.

    Prototype used 65-inch VA panel. With peak brightness as we told above at 2900 cd/m² and a black at 0.0018 cd/m² we have real contrast ratio greater than 200 000:1. In EU and US most probably it'll be only in 2020.

    Actually this guys matched top reference monitors approach - check our interview about such http://www.personal-view.com/talks/discussion/20797/nab-ny-2018-flanders-scientific-xm311k-hdr-reference-monitor#Item_1

    Such layer has 3000:1 to 5000:1 contrast, so combined it is staggering numbers, as in real room black level will reach OLED, and not in the large zones as usual, with brightness reading top Samsung sets.

    Check our interview below.

    Image retention is BIG problem for monitor used, all leading manufacturers and press made long time tests.

  • Do you have a specific link to a product from Flanders Scientific using two LCDs? (I saw many different kinds of monitors on their web page, but no obvious hints to the use of two LCDs.)

    Generally I'm not sold on the idea that "two LCDs" will outcompete OLEDs for consumer displays. I'm happily running a LG 4k OLED TV since 2015, both for movies and as a computer monitor, and "image retention" hasn't ever been a problem for me. The early model near-black uniformity issues have been sorted out in contemporary OLED TVs.

    I'm curious to see a Hisense ULED XD tested e.g. at https://www.rtings.com/tv/reviews/hisense - until then, I remain skeptic about this approach.

  • If you do account for reflections of ambient light at the display surface, then the achievable contrast ratio mainly depends on your surface coating/structure, and that is independent from the display technology behind it.

    Well, no. It depends on display tech a lot.

    Also, I am still missing a plausible description of how they manage to combine the filtering effects of two LCDs in front of the light source. After all, LCDs are based on modulating polarization, and if you put two similar polarization filters in the path of your light, their effect does not simply add up (or better: multiply).

    You can check how Flanders Scientific are doing the same thing.

    Their top reference monitors are made exactly such.

    And unfortunately for OLED, due to it's unsolvable problems, it will be mainstream way for consumer TVs also.

    Progress with backlight brightness and processors solve all the issues cheap.

    Poor manufacturers now have their main enemy - government who in their stupidity made wrong consumption limits on TVs, especially EU is known for this.

  • "A contrast ratio of over 150,000, exceeding OLEDs" is clearly a marketing lie. If you do not account for reflections of ambient light at the display surface, then contrast ratios of OLEDs are infinite, because black is black with them. If you do account for reflections of ambient light at the display surface, then the achievable contrast ratio mainly depends on your surface coating/structure, and that is independent from the display technology behind it.

    I think we need to wait for independent lab reviews before concluding that this is a real revolution :-)

  • Thing is launching finally.

    Display technology was manufactured in partnership with BOE and is called BD Cell. Hisense says it is proud the technology is fully Chinese.

    The display consists of two panels – a color panel which focuses on color control and the black and white panel which handles dimming, contrast, and details. There are also five chips inside the TV that efficiently control the backlight and images. Combined with the dual panels, the U9E has a contrast ratio of over 150,000, exceeding OLEDs; and a picture quality is outstanding.

    The Hisense U9e is also said to exceed the peak brightness, color gamut, color accuracy and HDR certification requirements of OLED TVs.

    The U9e will come in 55-inch, 65-inch, and 75-inch models. Only the 65-inch model is available this year at a price of ¥17,999 (~$2616), making it even more expensive than Sony’s 65-inch LCD TV for 2019. The 55-inch and 75-inch models will be available next year. Hisense didn’t reveal when the 55-inch model will be available for purchase.

    One strange thing is that 75 U9E at some expos had been mentioned as having 5376 Local Dimming zones, that is really small for such tech.

    Too thick, plus OLED is more energy efficient.

  • Works for cell phones too? Or too much energy?
