56.3: Performance Improvement of Compensation Circuit Using p-Type SPC TFT for AMOLED Driving

A new AMOLED compensation pixel circuit is proposed to improve the short term image sticking problem due to the hysteresis characteristics of p‐Type ASPC TFTs. A 3.9‐inch AMOLED display was developed based on proposed compensation circuit. The experimental and SPICE simulation results show the high...

Zusammenfassung:	A new AMOLED compensation pixel circuit is proposed to improve the short term image sticking problem due to the hysteresis characteristics of p‐Type ASPC TFTs. A 3.9‐inch AMOLED display was developed based on proposed compensation circuit. The experimental and SPICE simulation results show the high performance of the hysteresis compensation.
