Paper Abstract

Organic Light Emitting Diode (OLED) based displays are viable alternative to Liquid Crystal Display (LCD) displays. However, OLED displays are still costlier due to the low yield of production which is due to the visual defects in the displays. A defect-free display is a prime requisite for a flat panel display application. Hence it becomes important to understand the possible defects and their root causes. Here, we have created defects intentionally in a small OLED matrix and studied the possible visual manifestations in a Passive Matrix Light Emitting Diode (PMOLED) display by electrically probing and visualizing waveforms on a Cathode-Ray Oscilloscope (CRO).
