Nice...
Especially with the apparent demise of SED etc. Question is, how long does this realistically _now_ mean we've got to put off buying a new telly?
LG is to co-operate in the development of quantum dot-derived LED TV displays capable of generating "brighter, richer colours" while consuming a fraction of the energy of today's LEDs. The South Korean giant said it will work with QD Vision, the US developer of the electroluminescent quantum dot LED - aka QLEDs. The two will …
Another technology that we wont see (or will only see on smartphones or iPod Nanos) for a decade or more.
Didn't they say the same thing about being able to print OLED TVs on substrates cheaply and easily without changing the LCD production process significantly five years back now? We're still waiting on cheap OLED tellies.
At least we can now drool over the tech as it emerges, and we have a cool new acronym. yay.
They havn't paid the mortgage off yet.. they invested a lot of money in LCD plants based on a 20 year life for the technology.. but OLED appeared at year 5.. so what to do? write it off? make a loss? it'll never happen. Instead they'll tinker with LCD, move from CFD to LED backlight and pretend its the new OLED Tech as its got LED in the name... oh they have already.
unfortunatly progress is not driven by science, technology or education, its driven by capitalism.
The only reason a plant will do this is if someone ELSE does it first and starts affecting the number of TVs that they sell. THEN they'll retool with the same, or newer, tech and market it as "better" or sell it as "the same" but at a slightly lower cost.... Needless to say, NO ONE makes the jump until "someone else" steps first. Look at how Intel's [lack of] support for USB3/SATA3 has hampered rollout of USB3/SATA3 devices until someone released a certain SATA3-capabable SSD... Of course, if you're running Intel, your mobo has an addon chip allowing for SATA3/USB3 (if at all), but quite a few AMD boards now support it natively on the southbridge.
No , as the tools are what are mortgaged, the shed in which they are kept is the cheap bit. the money is in the equipment and the staff designed/trained to make lcds. the cost of any production line and ancillary supply lines, usually far outways the cost of the building in which it is housed, so yes re-tooling is how they will change over but when each of the 30 tools costs you $30million.. its no small job.
...modifying the existing tools to produce a slightly different product. Like what happened in auto plants during World War II. The equipment was basically the same; they just started building different things. Are you saying that OLEDs cannot be made at existing LCD facilities without making more than minor adjustments to existing equipment?
see my post above, just as sony said there is no future for the OLED this QLED will not arrive untill someone has paid for the LCD plants, so go buy an LCD TV and when the capitalists have enough money they'll buy/build a new plant. (more LCD's sold = quicker next tech)
Poorlumpypony, the confinement is at the nanoscale, i.e. the excitons are sort of 'trapped' in a box a few tens of nm wide , long and high . That forces them to occupy only a discrete set of energy levels, and hence emit narrow band light. Most other device structures only confine particles in two dimensions, sort of like being stuck inside a very large football stadium, you can roam around it but simply not jump out.
"the upshot is that you apply a voltage to the things and they emit light. Crucially, the voltage is very low, and the light is of a very tight frequency band, resulting in very specific, accurate colours."
more to the point this sounds like a VERY Good thing for future Lightpeak and related multi micro fibre channels of light for the massive giga shadow SMB/SOHO network of the near future... too
the question is, how long before they can produce Something of value in even smaller lower commercial quantities to start with!
... because it sucks to recharge my cell phone every (pick one - day, week, month. ). Why can't they come up with cell phones where the battery charge lasts 2 years or more, just like my, uh, FREAKING WRISTWATCH?
How about never recharging at all, shove an automatic mechanism in it, or solar cells. BTW, some watches have those, and the battery lasts 2 years IN THE FREAKING DARK. Give it enough sunshine, and you could pass it on as family heirloom, still working.
(Speaking of that, pub o'clock.)
On the other hand, with color-specific lighting, the screens build on that could get really impressive.
Drop the coat, it is 39ºC outside.
"Why can't they come up with cell phones where the battery charge lasts 2 years or more, just like my, uh, FREAKING WRISTWATCH?"
Last I checked, a wristwatch didn't need to send active signals to a tower X meters away. Put NTP in your wristwatch and see how long that battery lasts. Oh, and try making the backlight on your watch stay on for at least an hour each day. And give it a color screen rather than B&W.
BTW, solar cells for phones do exist. It takes ~3 DAYS in full light (during the summer even!) to charge an iPhone. I'm sure use will outstripe that. Oh, and the logistics of having to leave your phone (or in my example, a battery with solar cells on it) in the sun for that time....yeah.
