Abstract

The application provides an augmented reality display device comprising a projection source module (10) and an optical path module, wherein the projection source module (10) comprises a projection source (12), the projection source (12) has a curved light outgoing surface (12a), virtual image light (VL) is projected out of the projection source (12) via the curved light outgoing surface (12a), and the optical path module comprises a beamsplitter (20) and a reflector (60), wherein the virtual image light (VL) projected out of the projection source module (10) is incident on the beamsplitter (20), reflected by the beamsplitter (20) onto the reflector (60), reflected by the reflector (60), and then transmitted through the beamsplitter (20), entering a human eye (E) eventually. The application also provides a wearable augmented reality system comprising the augmented reality display device and a projection source module for the augmented reality display device.
