Abstract
A system for 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 system provides closely balanced currents flowing through column drivers located at or near end regions of a display area. The system 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 system additionally allows for balancing currents at adjacent columns or regions throughout the device.
