    ... a little bit anal to be sure, but which uses more power - having your screen on positive or negative?

    This was discussed before. The answer was, negative uses slightly more but it is such a tiny amount it would make no practical difference. Its the backlight that uses all the power.

    me too. Surely positive (BOW) settings mean that there are more white pixels, therefore using more power...

    dosent the neg use less becasue on the lcd the defalt(when you turn it off) is dark so it would take power to align the crystals to allow light through

    and no they are not little light bulbs thats OLED

    I'm pretty sure the display acts like most similar lcds. The panel is clear, and black pixels are formed by a very tiny application of charge (almost zilcho current) to change the polarity of the pixel area and make it dark, thus blocking the backlight from coming through. It doesn't work like little lights that use power for light pixels. The backlight is on behind the entire screen when lit. Only the polarity of individual pixels is changed to block the light. Doesn't use any noticeable amount of current.
