Abstract
A liquid crystal display is provided with elements arranged in matrix form and addressed by timing scanning and signal pulses so as to select particular display elements. According to input data, the display is made to move while maintaining its shape so that an analog of a mechanical system such as a dial or gauge having a movable pointer may be obtained.
