A driving method has been developed for a 2D‐3D switchable AMOLED using progressive emission PE or simultaneous emission SE. The proposed method is implemented by selecting PE mode for 2D to improve light emission ratio and SE mode for 3D to reduce left‐right crosstalk without sacrificing luminance. This method also improves the contrast ratio by removing unnecessary light emission and can offer better uniformity by increasing the threshold voltage compensation time. A 240Hz‐driven 30″ 3D AMOLED display was built and it was confirmed that there is no ELVDD surge current in the SE mode.
