    Before SED or OLED are even out they might be obsolete, with the development of diffraction gratings using artifical muscles:

    Interesting to say the least, although consumes a fair bit of power:

    "Initial experiments required thousands of volts to flex the muscle, but the team have now reduced that to 300" :eek:

    Very interesting. Although different, I was only thinking today that someone should create a display which uses reflected light from the front surface of the display rather than transmissive light (as is used in all displays at the moment).

    A buttefly does not have any pigment in it's wings, the colours are created by interference to light reflected from the surface of the scales on it's wings. If someone could make a pixel which has a patten on it which can change the pitch of that pattern, in theory it would be possible to produce colours from the reflected light hitting the surface, in the same way that we view a printed picture (colours are created by absorbtion and reflection of different frequencies of the light spectrum).

    This too should be able to produce the full range of colours visible in the natural world. I wonder if anyone has thought of this :)
