In this work, we investigate gray to gray response time degradation of AMOLED display and design AMOLED pixel to improve gray to gray response time. The pixel designed here is that compensation method is source‐follow type instead of diode connection. By using source‐follow, we proposed new AMOLED pixel structure and fabricated 31_inch OLED TV that achieved good Gray‐to‐Gray response time with 0.043 millisecond levels through improvement of bright shortage and brightness drop. Compare to the previously compensation method using diode connection, Gray‐to‐Gray response time is decreased extremely. Therefore, this pixel structure was very suitable for frame rate, large size and high resolution OLED TV application.
