2T1C digital drive has been investigated with stable white OLEDs. A 2.5″ QVGA digital drive AMOLED prototype exhibited quite stable lifetime under constant voltage stress. The lifetime (T50) of an OLED device with 40% aperture ratio was over 5,000 h at an initial condition of 442 cd/m 2 while the T50 at an initial condition of 175 cd/m 2 is estimated to be over 20,000 h even under constant voltage stress. Motion artifacts are also improved with an automatic refresh rate conversion with less impact on power consumption.
