<p>A method and 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 method and system provide closely balanced currents flowing through column drivers located at or near end regions of a display area. The method and system allow 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 and system additionally allow for balancing currents at adjacent columns or regions throughout the device.</p> |
