We futurists are still waiting for our roll-up TVs and cellphones. The concepts have looked pretty spectacular – who wouldn’t want to fold his laptop up like a napkin or roll her TV into a pen for their pocket protector? So… why don’t we have this ability yet? What advances in technology need to happen to make it happen? And, even so, will it happen within our lifetime? A recent study from a… → Read More
So far, I’ve avoided the CFL and LED light bulb revolution. The savings, it seems, come around in the second year, which means that whoever has my apartment next will have a reduced power bill. I could always take my light bulbs with me, but that seems a bit miserly. Besides, my power bill is like $5 a month and 90% of that is my fridge and my desktop.
But these Orbeos OLED lights are as bright… → Read More
The march towards an OLED future continues. As usual, the transition to yet another display technology is eagerly anticipated but fraught with obstacles. So exciting! One of the things they’ve been working out is the materials to be used for tinting the light red, green, or blue in various amounts. They’ve got good materials for red and green, but until some scientists at Pusan… → Read More
It seems that one of the limiting factors in miniaturizing OLED screens is the substrate. This isn’t surprising, considering the OLEDs themselves are microscopically thin, but I’m kind of surprised they haven’t moved on from glass substrates already since the benefits are so manifest. I guess cost must have been an issue, or else maybe there just was never a friendship like that… → Read More
[Image credit: University of Utah] The LEDs you see in use all over these days — in traffic lights, flashlights, and all over your computer — are able to convert somewhere between 50 and 70 percent of the energy passed to them into light. This high efficiency makes them ideal for those purposes mentioned, but high costs have prevented them from replacing other types of lighting… → Read More
