Abstract
An optical engine module including a display panel, a transflective layer, a polarizing reflective layer, a first bifocal lens, a first and second electrically controlled half waveplate is provided. The transflective layer is disposed between the display panel and the polarizing reflective layer. The polarizing reflective layer is configured to allow the light beam having a first polarization state to pass through, and reflect the light beam having a second polarization state. The first and second electrically controlled half waveplate are disposed between the transflective layer and the polarizing reflective layer. The first bifocal lens disposed between the first and second electrically controlled half waveplate has a first focal length for the light beam with the first polarization state, and has a second focal length for the light beam with the second polarization state.
