Tech Ping!........................
What?
“Our work demonstrates that meticulous control over nanorod composition and interface engineering can lead to disruptive advances in optoelectronic performance.”
What?
"We made a new computer screen. It's really cool."
Oh. That's nice.
After designing their new QRLEDs, the team tested their performance and efficiency. According to their study, the new designs turned electricity into light with 24% external quantum efficiency compared to 22% for older models.
LED bulbs are the best light bulbs for your home. Generally, LED bulbs are 90% efficient, CFL bulbs are 85% efficient, and incandescent bulbs are only 10% efficient. So, if your home is packed with incandescent bulbs – then you’re going to have higher electric bills.
Now I am little confused here, we are told leds are 90% efficient.
QueerLEDS?
What’s next, TransLEDs that swap polarity on command?
I bought a 4K OLED TV two years ago to replace my 1080P TV.
The difference was striking in clarity and brightness. Growing up in the CRT era of TVs I am really impressed with OLED. I waited for the prices to become reasonable.
At the time the 8K TV’s were just hitting the stores but why buy a TV that has almost no media available the takes advantage of it’s capabilities and will cost you an extra $100 a month in cable TV charges to get access to the little that is available?
The new TV’s are very thin and light in weight. This bothers me a bit as they are very fragile. I do wish they would armor them a bit. I have a teenager and a pre-teen in the house and they have already destroyed a couple of cheaper TV’s.
BiLEDs: worth with either AC or DC.
IOW, they found it by accident................
Oh, great. I turn on the phone and my face melts.
Oh boy! A seven segment display that I can use to serialize bronze castings.
That brings crappy programs and movies right into your home with breathtaking clarity.
You'll note they don't say "useful life." I don't like buying another TV every few years.
Are there any movies you’d recommend?
OLEDs and QLEDs were nice improvements, this sounds like another giant step in quality.
What network supports this?
Since I only have a couple of lamps with incandescent bulbs, and they are only on for a few hours in the evening, how much of a monthly or annual cost savings is there?
No thanks, let me have a citizens choice of incandescent bulbs, not a govt. mandated LED.
And while we're at it, give me back my high volume flush toilet. The govt. mandated toilets aren't worth shit.....(no pun intended)
I still get a kick out of turning on a LED with my PLCs and arduino.
As an aside. I watched a very enjoyable documentary about the guy who made the first blue LED.
