Patent ID: 11372244

Abstract:
The present disclosure provide a laser beam scanning display device and augmented reality (AR) glasses, comprising a focusing lens, a laser emitter located at a focal point of the focusing lens, a beam combiner, a micro-electromechanical assembly and a projection lens. The laser emitter emits trichromatic laser signals, which are irradiated into the beam combiner via the focusing lens. The beam combiner converges the trichromatic laser signals into a convergent laser signal and emits it to the micro-electromechanical assembly. The micro-electromechanical assembly scans the received convergent laser signal to generate a content to be displayed. In the above laser beam scanning display device, the content to be displayed, which is generated by the micro-electromechanical assembly, is displayed on the screen via the projection lens, which dispenses with any laser signal reflecting or transmitting means, thus reducing the volume of the device.
