Sony builds a 1,000,000:1 contrast ratio OLED (Organic Light Emiting Diode)

What is contrast ratio? The higher = higher resolution?

On every TV you have top white and bottom black. The number of shades of grey the TV can make in between black and white is the contrast ratio. Bear in mind that a shade of grey is a combination of RGB. So the contrast ratio gives you an idea of the number of possible colors a TV is capable of reproducing.

That said... there is no specific standard way of calculating CR so it's hard to compare exactly between brands. What's more the TV manufacturers have now created another stat called "peak contrast ratio" which is akin to "dynamic power" in an amplifier's power ratings. (It's made up or totally unrealistic in normal viewing conditions)
 
I love CES...I should call up my friend who's working the show and have him snoop around for me. *sigh*

Any word on when the iRiver Clix 2 will hit market?
 
in regards to display units (tvs, monitors), i stopped paying attention to specs in 1998 after seemingly every pc monitor advertised a .21 dotpitch....

One Million to One, finaly a ratio that can best a CRT.

*cough*

CRT in its heyday was about 50:1

Now, if you're thinking black levels... that's something different.

I have read some of the best CRT's have 20,000:1 or more.

.21 was usualy an exagerated claim.

Maybe on some of the commercial/profesional monitors. But even that sounds incredibly high.

I should dig around the store and look for an old brochure from 3-4 years ago. The best direct view sets were 35:1 and the best RPTVs were 50:1. (Mitsubishi Diamond, Sony XBR)

That sounds a little like 4bit grayscale to me.

hence my ignoring specs. as long as i stick to dell, panasonic, mitsubishi, etc... ill feel satisfied with my purchase :thumbsup:
 
Yeah when I sold Mitsubishi RPTV's the contrast ratio was 65:1 on their best sets. Look up the specs on the WD-55813 if you'd like proof.

There is no real "standard" in place on how contrast ratio is measured, and thus you'll see everything from 30:1 up to 1000+:1.

I'm not sure what they mean by 1,000,000:1 but the picture (judging from the photo) looks excellent.

I sold CRT TVs for 15 years. When the first plasmas came out with 500:1 contrast ratios we were WTF. CR is the most abused brochure stat there is. It's the modern day equivilant to lines of resolution. 😉

OLED usualy has a very fast responce time. The issue is weather or not they have fixed the blue rot, I know it has gotten better but I don't know if the problem is solved.

How long till they package it up with a rootkit, sell it for twice what it's worth and tell the buyer "Tough Sh!t" when it dies a few weeks after purchase?

It's called blue rot and is gradual phenominon and does not happen over night or over a few weeks. Yhey have made some progress in the area of stopping it, but I do not know how far they have gotten in completely eliminating the problem.
