A method of providing balanced currents at locations in devices requiring accurate,
matched and repeatable current sources, for example visual displays 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. The method allows for more closely matching currents at adjacent columns
in a device such as a visual display, wherein the currents are driven by separate
driver circuits, thereby eliminating discontinuity in brightness across the entire
display area and providing higher quality visual display devices. Another embodiment
provides closely balanced currents flowing through column drivers located at or
near end regions of a display area. The method additionally allows for balancing
currents at adjacent columns or regions throughout the device.
