Abstract
A mobile communication apparatus, an optical assembly, and an aperture module thereof are provided. The aperture module includes a first liquid crystal (LC) aperture unit and a second LC aperture unit. The first LC aperture unit includes a first LC layer and two first transparent electrode layers disposed on two sides of the first LC layer. At least one of the first transparent electrode layers has a first opening. The second LC aperture unit includes a second LC layer and two second transparent electrode layers disposed on two sides of the second LC layer. At least one of the second transparent electrode layers has a second opening having a central axis overlapped with that of the first opening. The aperture module is configured to control each of the first switch region and the second switch region to be at a light permeable state or a light shield state.
