More Information
Summary:A display device comprises row ( 5 ) and column ( 6 ) electrodes and a movable element ( 3 ) and means ( 17 ) for supplying voltages to the electrodes, wherein the row electrodes are situated on the movable element. The means supply, in operation, such voltages to the electrodes that use is made of the memory effect of the movable element. More in particular, the row electrodes are, in operation, supplied with "on", "off" and "hold" voltages and the column electrodes are supplied with "hold" and 'off'-voltages. Application of "on" voltages turns on the pixels in a row, simultaneous application of "off" voltages turns a pixel off. Application of a "hold" voltage to either one of the electrodes preserves the status of the pixel.
