Samsung shows off state-of-the-art 40in OLED TV Samsung has demo'd a 40in OLED full HD TV, but the company admitted that the screen is at the very limit of what it can manufacture today. "This 40in TFT panel is the largest size that can be made on our pilot line, and it cannot be mass-produced right away," a company spokesman admitted, Japanese newspaper Nikkei reports. " …
>Thats pretty frigging dim, your average panel has 500, you'd have to watch that in a dark room.
Old CRT TVs are around 100cd/m², LCD's are commonly around 300cd/m², so it's not as bright not unusual for LCD to be 200cd/m², the contrast ratio on OLED is much better, you wouldn't have to watch it in a dark room, I'm not sure where this "average 500cd/m²" comes from, given the typical range is 200cd/m² to 600cd/m² and in most lab tests the manufacturers exagerate anyway (I've never found a screen that meets it's quoted brightness), besides very bright screens can be horrible to use, it depends so much more on distance, viewing angle and contrast, 40" full HD with that contrast ratio is probably lovely.
Reminds me of the classic... "Yea, but these go to 11" bigger numbers don't always mean better.
Has anyone ever watched LCD screens set at full brightness? They're bloody awful. I keep mine set to about 100cd! To expand on what Frank Bough rightly said: manufactures have settings to make their screens super bright so they can inflate the 'dynamic' contrast figure to well above the level of the more crucial static pixel to pixel contrast figure, but they looks crap when the dark pixels are bright too.
200cd with truly dark adjacent pixels? f*** yeah!
I should also point out the colour claim is "can show *more* colours", which is not the same as equal to. Granted NTSC isn't a great standard to compare against but it doesn't mean it's a bad thing.
"This 40in TFT panel is the...."
Thin Film Transistor? I would have thought they'd want to drop that acronym, as to me, its closely associated with LCD tech, something they would not want to peddle cool new OLED tech as - as if its just a new form of LCD, which it clearly isn't.
I'm not sure even if OLEDs require a thin film transistor arrangement, but I suppose they do.
Well I cant wait to see these babies in the shops too, imagine having the deepest blacks imaginable!
Even my new Samsung Series 6 TV, although very impressive, cant manage this. It made watching Blade Runner somewhat dissapointing cos its such a dark film, esp. towards the end.
Now OLED on the other hand better be totally black when I see one in person, seeing as all it has to do is switch OFF the pixel!
No suppose about it. OLED does. Essentially OLED has a fairly short finite life. It's why many handheld devices using OLED resort to powering off the display frequently to keep the lifetime up. This does mean even a screensaver cannot be used, because that requires the OLED to be powered and eat into its lifespan.
But they may have improved this in big screen displays. I don't know.
Thing is though, LCDs also have a limited life in a way. The backlights will only last a few years before they can go. My Samsung LCD has hidden away a counter on the number of hours the light has been running. Presumably to ensure they can wriggle out of any warranty claims on it.
Had a Dell monitor backlight die a year after purchase, just out of warranty and Dell effectively said "bin it, buy a new one", and wouldn't even take money to repair it! Likewise my Acer laptop backlight died in just under 3 years.
Look in the small print on many LCD warranties and you may find the backlight is limited to a year, even if it's a 3 year warranty.
They should be easy to replace, but frequently they charge more than the LCD's worth to replace them. So if OLEDs can manage to outlast an LCD backlight, they're doing good.
"This does mean even a screensaver cannot be used, because that requires the OLED to be powered and eat into its lifespan."
You confused two things. OLEDs do have finite life time due to oxidation, and the way around it is by researching tighter membranes. OLED screens are powered off to extend battery life, because (opposite to LCD screens) OLED only draws power for lit pixels.
I am using AMOLED screen (Clix2), which is actual technology used for full-colour screens, more than a year now. Colours and contrast are absolutely briliant, no trace of fading, could be brighter though (it certainly does not have 200cd/m2, more like 20cd)
