LG to show 55in, 4mm-thick OLED TV at CES
Four-colour pixel tech on display
LG will be showing off its largest OLED TV at the Consumer Electronics Show (CES) next week having taken the telly tech to 55 inches.
Once heralded as the successor to the LCD panel, OLED has struggled to achieve the screen sizes other display technologies can manage. For a long time it seem OLED TVs wouldn't get any bigger than the early 15in and 22in offerings.
Even they were incredibly expensive, and no doubt LG's 55-incher will be too.
The set is just 4mm thick, mind, and each pixel's hue is formed from four colours rather than the customary three. Don't forget, OLED doesn't require a backlight: the pixels themselves generate the light. In addition to red, green and blue, the OLED TV has a white sub-pixel.
The upshot: an "infinite" contrast ratio, LG claimed. ®

"anything distracting immediately next to the screen." - like a girl in a mini-skirt?
Still not infinite.
It's only perfectly black if it doesn't reflect any incident light. Even in a completely darkened room with black walls there will be some incident light from other parts of the screen, even if it's only very small. Once manufacturers start using terms like "infinite" smell marketing hype.
aye thats the acid test of a good screen
When you notice the tech first and the pretty lady second; Then and only then do you know it is good tech.
OLED and it's derivatives do have perfect blacks, as there is no back light. Try reading the article.
