12.1: Invited Paper: Comprehensive solution for high image quality in medium and large‐size AMOLED displays throughout display usage cycle

Abstract

AMOLED display system based on external compensation and image data correction allows for accurate compensation for initial non-uniformity, TFT instability and OLED aging and thereby maintaining high image quality throughout display usage cycle. We discuss implementation of key components of the system including pixel circuit, sensing scheme and compensation algorithm along with application examples and evaluation results.
