In this paper, we suggest panel design schemes for large size OLED panel. With considerations on the reliability of oxide TFT, new pixel circuit is proposed to compensate threshold voltage shift of TFT and is designed in each WRGB sub‐pixel. Also, the panel design concept for improving power supplying is explained. Low resistivity Cu metal is used to allow large panel current with uniformly supplying power voltage. 55‐inch panel is successfully fabricated and demonstrated. Oxide TFT and white OLED with color layers are promising technologies for OLED TV.
