Retinal Projection
Embedded Files
Retinal projection technology is a display technology that generates images by scanning RGB laser beams two-dimensionally with a MEMS mirror and directing the reflected light from a mirror positioned in front of the eye through the pupil (a few millimeters in diameter) to project it directly onto the retina.
■ Key Features
■ Key Features
Low Power Consumption:
Since only a small amount of light is delivered directly to the retina, the optical efficiency is high, making the technology suitable for long-duration operation.Focus-Free Display:
The image is largely unaffected by the user's vision or focal distance, enabling a natural and comfortable viewing experience.Augmented Reality (AR):
Digital information, such as text, images, and 3D content, can be overlaid onto the real-world scene.
These advantages make retinal projection technology a promising key technology for enabling next-generation XR glasses.
■ Competing Technology
■ Competing Technology
Waveguide-Based Displays:
Due to significant optical losses, waveguide-based displays are inherently less power-efficient, making low-power operation difficult to achieve.
