A new approach has been developed to improve AMOLED's image quality. F ast T ransient C ompensation M echanism (FTCM) provides a good ability on Vth compensation, based on sub‐pixel circuit structure consisting of 6 TFTs and 1 capacitor. Furthermore, the P‐type GOA in AMOLED panel is designed for pixel driving and enhances displaying quality at low gray scale.
