An the human eye can only distinguish so much of resolution. Similar to
camera megapixels. For average size photos, the human eye can't view
beyond 6 megapixels, some can see 8. The difference is during enlarging
when they become noticeable.
Only some of those, the more expensive organic LED ones, are that.
The full array LED TVs just use LEDs for backlighting, not for generating
No more Sony crap for me. I had one of their $2000 LCD TVs, it lasted abou
4 years, then the cable that's bonded to the panel started to separate,
resulting in first just a bad line or two, then progressive picture loss.
I googled, found it was a common problem, lots of pissed off customers.
I took it apart, managed to do so gluing and retrofitting to try to push
against it, keep it in contact. That worked for about 3 months.
Sony offered a couple hundred bucks
off one of their new TVs as their idea of how to make up for it. I said
screw you, Thanksgiving Black Friday I picked up a Westinghouse 55" at
target. Four years later, it's still perfect and the picture is perfectly
fine, I don't miss the Sony baloney.
I also had one of their home theater systems that failed after just a
few years too. That was weird too. The inputs went, one at a time.
When it first stopped working I switched from electrical to optical and
that worked for another year or so. Then that input went, I think I
switched again and then none worked.
You must have missed my followup post where I specified over the air stations.
I don't think TV stations are in any hurry to spend the big bucks to go to the
ATSC 3.0 standard.
It took forever to go to digital.
I seem to recall that there was a problem with overheating and differing
efficiencies and light vs current curves of the colours. Also the colours
may look right but often were not.
I don't know what the likes of Sony are doing but I guess it depends on
I would not say they are any worse or better than others, but sadly in
today's market the makers do tend to cut corners, and depending on which
corners get cut it affects life.
Samsung tend to suffer with cheap capacitors, Sony often don't test
enough, this particularly shows in mechanical rigidity, and firmware cock
ups. Panasonic expensive gear seems very good, but it looks like the cheaper
end are badge engineered off the shelf products.
Large TV sets are on offer with OLED technology. 55 inch, 65 inch, prices to match.
There are a limited number of OLED substrate suppliers. It appears
the materials are modular enough, to scale up the design.
There are different types as well. QD is Quantum Dot.
"Quantum dots have properties intermediate between bulk semiconductors and
discrete atoms or molecules. Their optoelectronic properties change as a
function of both size and shape"
"Another pain-point for LG will be that Samsung's QD-OLED will
actually use the "problematic" blue pixel as its light source and
use red and green QD colour filters that in theory, decrease the
chance of burn-in. If Samsung's QD-OLED is able to achieve this,
and avoid burn-in, the panels will actually be able to show
"true colours" as it will not use white pixel filters."
It appears the writers of these articles have taken a few
too many "drama classes" in school.
