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.
Claims8
An electronic analog display device for displaying a display pattern having a predetermined configuration, the position of said predetermined configuration in said display being variable in accordance with an input signal, said device comprising:
- a display unit including a two-dimensional array of a plurality of electro-optical display elements each energizable in accordance with signals applied to its two inputs;
- coupling means for coupling one input of each element in a row to a corresponding row conductor extending in a row direction, and for coupling another input of each element in a column to a corresponding column conductor extending in a column direction;
- and
- control means for applying to each row and column conductor one of a predetermined number of control signals selected in accordance with the value of said input signal, said predetermined number being less than the number of said row and column conductors, to select a group of said elements defining said predetermined configuration at a position along said row direction which varies in accordance with the value of said input signal.
