A touchscreen liquid crystal display that includes a liquid crystal
display including a viewing surface, a liquid crystal area containing
liquid crystal located behind the viewing surface, a plurality of spaced
apart elongate first electrodes located on a viewing surface side of the
liquid crystal area and a plurality of spaced apart elongate second
electrodes located on an opposite side of the liquid crystal area, the
first and second electrodes overlapping to form an array of liquid
crystal pixel elements, at least some of the first electrodes being
displaceable towards the second electrodes in response to external
pressure applied to the viewing surface. A control circuit is connected
to the first and second electrodes for controlling the operation of the
liquid crystal display. The control circuit includes (i) a driver circuit
for driving the electrodes for selectively controlling a display state of
the pixel elements; and (ii) a measurement circuit for detecting
displacement of the at least some of the first electrodes in response to
external pressure applied to the viewing surface.
