I recently found myself musing about display technology for informational purposes. I've been randomly exploring the various options out there. People seem much more inclined to use displays that were traditionally classed as a televisions to run all day displaying small amounts of information, on the basis that they're backlit. I've been watching the development of network power, and the idea that you can now drive lighting and speakers from a network system, leads me to believe that as "television" power requirements drop, there will be network screens. I'm inclined to go in a different direction personally. I think ultra low power e-ink style panels with a tiny microcontroller is far more effective, for infrequently adjusted informational displays. It seems far more reasonable to use e-ink for something like a building directory that does change, but on the scale of weeks or months.
