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.
