The only downside of OLEDs is impurities in the inks.....which is what the canandians should of been working on improving.
LCD average span = 60,000
Some inks used in OLEDs have an aveage lifespan of 150000.
Instead of using transistors, you have leds.
Leds are used to give hdr effect........
So why get LCD Hdr ?
Nothing to get stuck during the lifespan of an OLED and failure means total matrix failure with is an oled downside.......
Technology is improving........
OLED\PHOLEDS will lead to
Paper thin\flexible monitors\displays\tvs
The applications are limitless, especially if the developement technology is inkjet\bubble jet printers.
Organic Transistors
For example a multifunction device with is a pen and a laptop.......the laptop is rolled into the pen......just unroll
Example...
John Doe: My laptops is 3.6 pounds....what about your's
Jane Doe: My laptop weighs .5 ounces
Also, flying cars are not to far off either.......they have to work out problem in which some objects implode when the high frequency electricity interferes with radio waves......
Cold fusion is also not far off.....just a few composition problems......
The only things that are not even visible on the horizion is warp\hyperspace travel and time travel......
