Unfortunately, the options are somewhat limited on how to make LCDs better suited for certain uses. They're actually fine for the majority of users. I think because of certain inherent limitations of LCDs, at some point in time we'll probably end up with something radically different.
Unfortunately, one of the most promising technology
SED has been abandoned, partly due to some unnecessary litigation, partly due to the recession, and partly due to the competitive pressure from the ever better LCDs. A somewhat similar technology,
FED is on life support.
So for all practical purposes, right now it's either LCD, plasma, or a leftover CRT. (of which there are still plenty)
