ABSTRACT:
Image quality is improved in an rms-responding, passive matrix display system (10) by correcting for voltages induced onto row addressing electrodes (22) by voltage transitions on column electrodes (24). Net crosstalk voltages sensed at nodes (88N and 88P) between a row driver (72) and voltage sources (70N and 70P) correspond to the voltage induced on a row electrode plane (136). A correction voltage corresponding to the net crosstalk voltage on the row plane is applied to the voltage sources to correct the rms pixel voltages for the crosstalk.
