DEFINITION

Classification: 345/30

PLURAL PHYSICAL DISPLAY ELEMENT CONTROL SYSTEM (E.G., NON-CRT):

(under the class definition) Subject matter wherein the light-generating or light-controlling display elements* are provided as an arrangement of plural segmented and matrix display elements* or as a flat panel array with selective electrical control.
