Design of system-on-glass for poly-Si TFT OLEDs using mixed-signals simulation

Abstract AMOLEDs (active-matrix organic light emitting diodes) employing poly-Si TFT have been used to integrate peripheral circuits on a glass to reduce the cost through the use of dead space on the glass. The system-on-glass (SOG) development provides enormous challenges to the developers, usually verifying the SOG by transistor-level simulation. IR-drop modeling is needed to reduce the uniformity degradation in the OLED image quality. This paper presents a full panel simulation technique for OLED driver and pixels that is integrated on a glass using the mixed-signals circuit design and the proposed process shows excellent capabilities relating to the capacity and the speed.
