A new internal compensation method for OLED display with high mobility oxide TFT is presented. The differential offset method was devised to make an offset voltage adapted for each pixel utilizing the behavior of the source follower type circuit. It can preemptively eliminate not only the sensing error but also V_th dependent voltage errors including after-sensing steps. Fabricated 5.5-in. QHD OLED displays have showed improved uniformity.
