Rocket Fuel Speeds Transistors
Mick Ohrberg writes "The rocket fuel hydrazine has been proven to increase the speed of thin-film transistors, which are used in LCD displays. It's also much cheaper to produce these transistors in a new "wet" manufacturing technique, based on creating the thin layers by using the centrifugal force caused by spinning the substrate. The result? Well, if the manufacturing cost plummets, maybe that 42" LCD monitor for my PC will be within (financial) reach soon."
Refresh rates are related to how fast the actual liquid crystal material can reorient itself in response to the applied voltage. So, unfortunately, unless they also use a new type of liquid crystal, the answer is probably not.
From the EPA and CDC. Perhaps Outsourcing LCD production is a good thing, after all?
Laugh while you can, monkey-boy!
Hydrazine doesn't play nicely with organics, and there's no tin sulphide in an OLED, so no.
CRT won't die until the price of LCD's go down (which this could help) and maybe more importantly, when the quality of LCD's (color depth/range, "refresh rates" etc) matches CRTs.
WWJD.... for a Klondike bar?
This article (in German) says that you can make cheap, flexible electronics with this stuff.

The hydrazine is only used while fabricating the LCD, it doesn't stay in it.
It's used as a solvent to put a layer of TnS2 on the substrate.
I'm no expert on this, so go read online for more info.

The ultimate goal of science is to unify all forces of nature to a single law that can be silk-screened onto a T-shirt.
Refresh rate, pixel decay rates, attainable colour space, non-native resolution pixel interpolation, RGB vs BGR for sub-pixel antialiasing, mean time to failure and fade, (semi) standard interfaces, etc...
As far as I am concerned, with no ego/space/power consumption restrictions, a CRT is far and away superior for most applications.
Re: the text performance on LCD, I assume you are using subpixel interpolation to get a usable display? Or are you just referring to DOS style low res character screens?
If subpixel, shame it is a work around to try and achieve much of the same readability of a CRT. It's even more of a shame that the technique will not work on portrait orientation LCD screens (think PDA) unless they have been manufactured specifically for this purpose (I expect they will soon). Then there is the RGB/BGR problem requiring user intervention and/or confusion.
You should NEVER have visible flicker on a decent CRT (unless you are comparing your new 2003 LCD to your old 14" running @60Hz). As for "sharper pixels" you are technically correct - unfortunately sharper rectangular pixels does not a smooth diagonal line make...
I use LCD's and CRT's extensively at work and always prefer the CRT.
