wow 8k and glassless 3D technologies.

Quantum Dots looks interesting, I wonder what these new sets will look like on the inside!

I want to get one, and dig into it to see how its built

Re: Look at what we will be fixing in the future

It's quite interesting but a few things to mull over...

OLED TV is like plasma: excellent contrast, excellent colour, not quite as bright as LED TV, and uses more power than LED TV. In theory the "one true successor" for people who enjoy picture quality over raw brightness. It is more power efficient than plasma and potentially cheaper to make. Most of the power electronics are on the panel itself making repair difficult if not impossible, power supply requirements for 55" 1080p OLED from LG are 20V @ 11A (panel VCOM, OLED matrix), and 15V @ 1.5A (same as LCD AVDD, for TFT drive), and +22V/-8V VGH/VGL (~50mA each)

Quantum dot takes normal LED backlight in LED-LCD BLU and replaces it with QD surface, that emits yellow light when blue light hits it. Sort of like how a white LED works but in bigger format. Not a new technology, has slightly higher energy efficiency and will be cheaper to make. Any claims to better PQ are nonsense.

4K/8K is a waste of time for any screen <70". Maybe works for Americans with their big living rooms. 50" is far too big for my room. At 6 foot, my 50" Kuro has maximum resolved detail at 1080p. Moving to 4K would provide no benefit. 4K content is also currently vapourware... buying a 4K TV now is a bad idea as the standard for 4K Bluray has not yet been set in stone, it may require a different HDCP which will make current 4K TVs useless.

oh hell,there goes me 20 meg analog scope then for diagnostics! ,wow.

id love to have a glimpse of the SCH on these wouldnt you?lets hope we arnt looking for vestal training manuals a year down the line though,it looks lovely on the outside ,but we all know the score?

brill tech though,possibly all SMD PSU?,the questions are endless,but all the same exciting

this post needs to be a sticky,the next gen repairers like us will look at this forum and see that we told them so.....,gem tom.

Re: Look at what we will be fixing in the future

and looking beyond 4k reso,sharp are looking to increase reso by 168%,whats the point????,greater reso more power draw,the eye can only take so much color ,personally i would be worried from eye damage ,people having a 70"4k screen in a bedsit ,it would be like having yer eyes flame throwerd!

"and looking beyond 4k reso,sharp are looking to increase reso by 168%,whats the point???" Bragging right.

Exactly. A local supermarket near me has 42" 4K TVs. Seriously overkill; you'd have to sit closer than about 3 foot to get benefit of that!

I bet with broadcast 4K they'll cut bit rate right down so it'll look worse than 1080i. 4K progressive bandwidth is ~3x as much as 1080i for any given broadcast, with no major changes in picture quality. But I'm sure they'll try making it 1:1 on bandwidth...

Re: Look at what we will be fixing in the future

OLED will be my next replacement when the time comes. I really like the small OLED display on my Vita and I am sure the panel displays will be even better.

I do think 4k/8K is a sales market gag imo.

yep,4k to 8k is just like you wont notice the difference,they will bring out contact lenses next, that project in 3D to watch these tv's,but make them harder to see through so going full circle you end up with 720p again,money for old rope :
