Those messages didn't show up when I did a google search. I like it. The thing to do is make the lcd reflective though in my opinion and come up with a way of being able to turn the backlight when it isn't needed. That way it can be used in full sunlight plus save power. The color of a elctroluminesant backlight (which is what they were talking about) isn't pure enough to keep the LCD's good color plus they are bulky and need really high voltages. There are two ways of doing this that I know of. Either add a reflective layer onto the back of the LCD so it will reflect part of the ambient light and also transmit the backlight when needed. I don't know what's availible for color screens though- basically you need something that won't mess up the color. The 3M RDF-C reflective is pretty good on mono displays and might work. Then the backlighting wouldn't have to be changed except to be able to turn it off. Or a person could pull out the FL backlight and add something like a series of white LEDs using a fiber optic backlighting panel. The fiber optic panel will work as a reflective surface so a reflective film isn't needed and will turn the transmissive display into a reflective one (at least according to claims made by a manufacturerers rep) http://www.poly- optical.com/ProductApplications/H2.HTM. I would think if about 5 high brightness white leds would be equivant brightness to the FL.
