ABSTRACT:
A method of providing balanced currents at locations in devices requiring accurate, matched and repeatable current sources, for example visual display devices having arrays of light-emitting sources. In one embodiment, the method provides closely balanced currents flowing through column drivers located at or near end regions of a display area portion of a visual display device. An additional embodiment of the method allows for balancing currents at adjacent columns or regions throughout the display areas of a visual display device.
