Abstract
A planar matrix of display picture elements is operated by supplying power to the picture elements by a high current planar drive electrode connected to the picture elements, and a planar counter electrode slightly separated from the picture elements' display dots, and by addressing the picture elements with low current leads parallel to the plane of the matrix. The planes of the electrodes are parallel to the plane of the matrix. The elimination of high current power leads improves response time and resolution. The separation of the counter electrode from the display dots eliminates the need to refresh the picture elements. An isolation transistor in series with the drive transistor allows simultaneous color change of the entire matrix by simultaneous turning on and off of all isolation transistors.
