Abstract
A liquid crystal display comprises multiple capacitors which apply electric fields to liquid crystal material located between the capacitor plates. In the invention, each capacitor is associated with a sensor which detects the presence of a hand-held stylus. The detection can be done optically, acoustically, by pressure, by temperature, or by other means.
