To explore the practical size limits of passive-matrix polymer light emitting displays, a 4-inch diagonal monochrome QVGA display was simulated, fabricated and tested. To design this display, a simulation program was developed which takes into account the multiplex rate, aperture ratio of the pixels, parasitic capacitance in the display, series resistance of the anodes and cathodes, and the decrease in efficiency at higher applied voltages. The effects of these parameters on the power consumption will be addressed. In addition, technological aspects of introducing a shunt metal in the pixels will be presented. Finally, the measurements of the fabricated display are compared to the simulation and discussed.
