Wallpaper for my laptop

Well.. I asked and he basically said that it depends on the type of LCD but it does require a tiny amount of power to change to a white state from black but it's negligible and the real savings would be made in turning off/dimming the backlight.

For a man that has his name on an LCD patent I was surprised at how straight forward his answer was.

Cheers !

Good to hear it conformed by a LCDologist. :)
