Hopefully this all works.]]>May 26th 2009 10:48AMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/
It's a shame because the demo model I saw was awesome. Basically a 1mm sheet of glass with a bright clear display on it. 180 degree viewing angle too.]]>May 26th 2009 5:53PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 10:54AMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/

I have, however been reading about how circuit printing tech is going to bring affordable large OLED panels into the home for 5 or 6 years.

So to reiterate, it's about fucking time.]]>May 26th 2009 2:14PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 3:04PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 5:14PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/
Epson will exhibit a 14-inch OLED display having resolution equivalent to a 37-inch full-HD display. The prototype display was trial-manufactured using Epson's inkjet process.

So, does this mean an actual 14" 1080 display, or that it just looks like 1080 because it's only 14".

If the former, and they can maintain that pixel density on larger screens, say hello to semi-affordable 8k home displays. ]]>May 26th 2009 11:22AMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 1:19PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 3:23PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/I wonder how much power a single dot on an OLED display uses, I assume a LCD dot requires several factors less since they don't give off light themselves (the dots themselves I mean, not the whole display including backlighting).

So anybody know what the voltage/amperage is per pixel?

Google doesn't help much, although I did see on a samsung site a mention of disadvantage of PM-OLED listed as 'higher power inappropriate for wide displays" and "Lower brightness with increased number of lines"

The last two lines are most important, but I wanted to include the whole thing.

The background current, however, is comprised of the leakage current through all the TFTs T2 and Cs capacitors in the OLED display, because all the sub-pixels are tied to the supply voltages VDD and VSS through the column power lines in a conventional OLED display. For example, a VGA resolution (NTSC-monochromatic) display has 640×480 pixels (m=640, n=480). In the case of a full color display, each pixel is made up of three sub-pixels, red (R), green (G), and blue (B). Therefore, the total number of columns in a VGA full color display is 640×3=1920 columns (m=1920). Thus, the total number of sub-pixels in a full color VGA display is 1920×480=921,600 sub-pixels, or almost a million sub-pixels. Typically, the leakage in a single TFT T2 can be 10 picoamperes. Therefore, the total background (leakage) current of a VGA full color OLED display can be approximately 10 microamperes (1 million sub-pixels×10 pA). Since the background current (10 microamperes) is very large compared to the current increase resulting from a single turned-on sub-pixel (between a few nanoamperes and one microampere), it is extremely difficult to measure the sub-pixel current accurately.

If I'm reading this correctly, it looks like the per pixel use is closer to 1 microamp than 1 milliamp.

@elbravo

2 years ago who would have guessed that we'd see affordable Full HD image processors on handheld devices, with a little luck we'll see one launched at e3 next week. Who knows what's next.
If Red-ray has half the specs claimed storage and decoding won't be a problem either, and considering how many pixels worth of 3d graphics the newest video cards can spit out, I'm not real concerned about running out of pre-rendered 2d pixels.
For cabling, I buy my hdmi cables from monoprice for $10, I plan on getting whatever replaces it for $12 or $13.]]>May 26th 2009 5:48PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/But there must be a reason why not even sony, and not even for all the money, can muster a large OLED display.
Still I hope fixes will be found, I'm just not sure that the author's statement that the subject of this article fixes 'the last remaining excuse" is completely true, and I don't get my hopes up too much at this point, although I'm convinced eventually something will be available that beats LCD massively.

I'm guessing we're still 24+ months away from a OLED panel of any size for $1500.

However, unless 24fps playback is a big issue for you you can't really go wrong with the new panny PDPs.]]>May 26th 2009 2:11PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 12:08PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 1:26PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/May 26th 2009 12:26PMhttp://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/http://www.engadget.com/2009/05/26/seiko-epsons-inkjet-tech-brings-big-screen-oled-tvs-inches-clos/
