We propose a new 2D/3D switching method using the lens effect solely caused by LC director distribution under controlled non‐uniform electric field distribution. By optimizing electrodes structure and applying this lens cell to LCD of 17.1 inches size in diagonal, we successfully verified the lens on/off effect of LC lens and the switching between an auto‐stereoscopic 9‐view 3D mode and a clear 2D mode. Comparing with previously reported structures of other switching lens, our proposed structure is the most competitive in respect of structure simplicity and process compatibility.
