A display device that both displays visual information and that serves as
a mechanical actuator to generate input signals is disclosed (i.e.,
display device is not only an output device, but also a mechanically
actuated input device). By way of example, the display device, which
displays visual information such as text, characters and graphics, may
also act like a push or clickable button(s), a sliding toggle button or
switch, a rotating dial or knob, a motion controlling device such as a
joystick or navigation pad, and/or the like. The display actuator may be
incorporated into any electronic device to control various aspects of the
electronic device. Alternatively, the display actuator may be a stand
alone device that operatively couples to an electronic devices through
wired or wireless connections. In either case, the display actuator can
be configured to generate commands, make selections and/or control
movements in a display.
