AR optical display module and augmented reality equipment

Abstract

The invention discloses an AR optical display module and augmented reality display equipment. The AR optical display module comprises a polarization assembly and a first transflective part which are sequentially arranged along an optical path, wherein the polarization assembly is used for reflecting incident image light to the first transflective component, and the first transflective component isused for reflecting the image light and transmitting external effective light; the image light reflected by the first transflective part and the transmitted external effective light reach the polarization assembly, and enter human eyes after being transmitted by the polarization assembly; the polarization assembly is also used for absorbing incident external stray light. According to the invention, the polarization assembly is used for eliminating external stray light, thereby improving the contrast ratio of light (image light and external effective light) needed by a user and external straylight, and improving the watching experience of the user when the user uses the AR optical display module.

Description

technical field [0001] The present invention relates to a display device, in particular to an AR optical display module and an augmented reality device. Background technique [0002] Augmented reality (Augmented Reality, referred to as AR) technology is a new technology that "seamlessly" integrates real world information and virtual world information. Information (visual information, sound, taste, touch, etc.) is simulated and superimposed through computer and other science and technology, and the virtual information is applied to the real world and perceived by human senses, thereby achieving a sensory experience beyond reality. That is to say, the real environment and virtual objects are superimposed on the same picture or space in real time. [0003] like figure 1 A schematic structural diagram of an AR optical display module in an existing AR glasses or an AR display device is shown. The optical system of an existing AR display device includes an image source 11 , a b...
