Abstract
An electrical device containing pixel circuits, where at least one resistor is present within one pixel circuit to mask systematic luminance variation in organic light emitting diodes. The resistor can be located at one or more locations between electrodes. Each resistor has a defined resistor density, with distinct resistor values among pixel circuits to produce random variations in pixel luminance across a display containing plurality of pixel circuits.
