<p>A driving circuit includes an array of driving elements that selectively supply current from a power supply to an array of driven elements at a rate responsive to the difference between a control voltage and the power supply voltage. The control voltage is furnished to the driving elements through a conductive member that extends parallel to the array of driving elements. The driving circuit includes means for adjusting the control voltage independently at each end of the conductive member, to reduce variations in the current supplied by different driving elements.</p> |
