AUGMENTED REALITY DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18097861 titled 'AUGMENTED REALITY DISPLAY DEVICE
Simplified Explanation
The abstract describes an augmented reality (AR) display device that uses a display engine and a waveguide to project and output light. The display engine consists of a light source unit, a reflective display panel, and a projection optical system with an iris and a projection lens group.
- The light source unit is positioned near the iris, away from the optical axis of the projection optical system.
- This positioning ensures that the incident angle range of light entering the display panel does not overlap with the reflection angle range of light reflected from the display panel.
- The iris has an effective opening through which the reflected light from the display panel passes.
Potential applications of this technology:
- Augmented reality (AR) devices and headsets
- Gaming and entertainment industry
- Industrial training and simulations
- Medical and healthcare applications
- Navigation and mapping systems
Problems solved by this technology:
- Overlapping incident and reflection angles can cause interference and reduce image quality in AR displays.
- By positioning the light source away from the optical axis, the device ensures that the incident and reflection angles do not overlap, resulting in improved image clarity.
Benefits of this technology:
- Enhanced image quality and clarity in AR displays
- Reduced interference and artifacts
- Improved user experience and immersion in augmented reality environments
- Potential for more compact and lightweight AR devices.
Original Abstract Submitted
An augmented reality (AR) display device includes a display engine configured to project light of an image, and a waveguide configured to receive and output the projected light. The display engine includes a light source unit, a reflective display panel, and a projection optical system. The projection optical system includes an iris and a projection lens group arranged between the iris and the reflective display panel. The light source unit includes a light source or a light exit end positioned near the iris in a position deviating from an optical axis of the projection optical system, such that an incident angle range of light incident to the display panel does not overlap with a reflection angle range of light reflected from the display panel. The iris includes an effective opening through which light reflected from the display panel passes.
