OLED keyboard solution?

    interesting idea:-
    OLED / LCD keyboard, but using optical fibre technology to send the
    signals and power to each key instead of wires.

    this removes the need for any moving parts apart from the keys
    themselves.

    its possible to use infrared instead of visible light and individually
    address each OLED (continuous power to non

    active cells) with capacitor keep-alive on each key.

    perhaps this might be useful?

    iirc optimus keyboard's main headache was that each key needed multi-
    lead flexis that then caused reliability

    problems.

    a budget version of this could be done using white LEDs to "backlight"
    each LCD panel and infrared to address them.

  2. Optimus now uses fixed OLEDs under a moving transparent keycap. Problem
    solved.
