Abstract
A system and device for driving high resolution monitors while reducing artifacts thereon. Utilization of Z-inversion polarity driving techniques to drive pixels in a display reduces power consumption of the display but tends to generate visible horizontal line artifacts caused by capacitances present between the pixels and data lines of the display. By introducing a physical shield between the pixel and data line elements, capacitance therebetween can be reduced, thus eliminating the cause of the horizontal line artifacts. The shield may be a common voltage line (Vcom) of the display.
