An optical system for displaying 3D images includes a pixel array having a plurality of pixel elements, a lens module and a control unit. The lens module has a plurality of tunable lens elements and is disposed on the pixel array, where each tunable lens element has a light incident surface that faces a pixel element of the pixel array, and receives light emitted from the pixel element. The control unit is coupled to the lens module, and is utilized for controlling focal lengths of the tunable lens elements. |
