Wearable display using circularly polarized light

The present invention relates to a transparent, small-sized, and wide-viewing-angle wearable display which is characterized by having a circularly polarized light maintaining and reflecting unit and a circularly polarized light reversing and reflecting unit, and by reflecting light twice by using a reflective circularly polarized film, the curvature radius of a concave half mirror is large, the circular polarization maintaining and reflecting unit enables specific circular polarized light to pass through and keeps other circular polarized light as circular polarized light and reflects the specific circular polarized light at the same time. And the circular polarization transmitting and reflecting unit reflects the light of the display, which passes through the circular polarization maintaining and reflecting unit, to the circular polarization maintaining and reflecting unit, and the rotating direction of the circular polarization light is reversed in the reflecting process. 本发明涉及一种透明、体积小、且视角广的可穿戴显示器，其特征在于，具有圆
