Abstract
An apparatus to determine and apply a voltage to precharge current-driven elements in a matrix. During ordinary scan cycles, a conduction voltage is sensed while the elements conduct a selected current. While not conducting the selected current, the sensed conduction voltage is averaged with other conduction voltages, and based on the averaged voltage a precharge voltage is provided during a precharge period of the scan cycle.
