OLED TVs Arriving Within the Next Three Years
Anonymous Howard writes "Toshiba and Matsushita, in a joint venture, are going to be bringing OLED TV panels to market within 3 years! Granted, the size of the panel is only 20.8 inches, but that is a huge step up from the small OLED screens used in cell phones and other portable devices. It will have a resolution of 1,280 by 768 pixels (WXGA) and handles 16.7 million colors. No specifications on contrast, brightness, or refresh rates have been released, but such specs wouldn't necessarily be indicative of OLED displays to be released in three years' time."
Woohoo! I can't wait to buy one (though I'll likely wait for 32+" versions.
I was hoping for superior LCDs like those used in the OLPC. Jepsen developed an LCD display that, instead of using a crappy high-power fluorescent backlight and filters, uses a bright-white LED and a diffraction grating to deliver a display. This results in a much wider gamut, because of the wider color gamut of the white LED. It also uses 1/7 the power of a normal LCD display, because the light comes from the LED and gets redirected out the proper pixel; the brightness of the LED is adjusted as needed (an LED switches on/off effectively instantly, you can read the network signal on gigabit ethernet by sticking an LED inline). It's also cheap because existing LCD fabrication technology can be easily modified in place to do this (retooling), rather than being completely replaced with OLED fabrication technology.

When you've got a $5000 20" OLED set, and your buddy's got a $3000 50" plasma 1080p set, who's going to win the pissing war, or host the cool SuperBowl party??
OLED displays degrade very rapidly, from day 1 on... the blue elements have a life-time of about 5000 hours, the red and green about 60000 hours. You can expec to get about 40000 out of a typical display, which of course will look like crap due to loss in color fidelity.
I've very sceptical of this claim of OLED TVs in 3 years. Remember ?
At 20 inches, it doesn't need to be 1080p. You couldn't tell the difference if it was, so it really doesn't matter.

2*2*2*2*2*2*2*2*3=768. For 4:3 screens(thats where the 3 comes from), there is some reason to presume that it increased addressing efficiency(memory wise) to use a power of two and it just got pulled along for legacy reasons. For other ratios, who knows, but probably inertia as much as anything else(and addressing that many lines is straightforward as 3 blocks of 256, which is probably as good a reason as any).
Nerd rage is the funniest rage.
yes they have; now up to 20,000 hours

In order to kill your OLED TV with a 20,000 hour life blue, you would have to leave it on the blue screen for 54.79 hours per day. A quick back of the napkin calculation reveals that you are in fact a dumbass.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
The only advantages of SED over OLED are sideways viewing angle (OLED is better than LCD, but it still mostly wants to project light in one direction) and lifetime. OLED is superior in every other way; contrast ratio, black level, power consumption, weight, flexibility (of which SED has none), cost of production once the processes are ironed out, and probably the amount of energy consumed and pollution produced in making the things.
