PinMR™ (”Pin Mirror™) Technology
Numerous AR global leaders have been diversely attempting to endeavor to develop AR devices using the Half-Mirror Combiner, Diffractive/Holographic Waveguide or Geometrical Waveguide, yet they have not met end-users’ needs and expectations. This is mainly owing to bulky form factors, narrow FoV, poor color expression, high prices, and costly and complex manufacturing mainly caused by the complex structure of the optical system. All these issues vitiate the widespread commercialization of AR devices.
PinMR™ technology LetinAR invented was inspired by the pinhole effect, the process of placing a pinhole before the human retina resulting in clearer images of the object. By switching pinholes with tiny mirrors, the light from a micro-display can be reflected and guided into the pupils. The mirrors are invisible to the human eye – seamlessly along with real-world images. PinMR™ with its incomparable performance resolves the issues identified by consumers and AR companies so far, establishing itself as the frontrunner of the field.
LetinAR’s proprietary PinTILT™ technology focuses on reducing the form factor of reflective-based waveguides based on the process of folding the optical structure of traditional reflective optics. While maintaining the great image quality of reflective-based solutions, LetinAR could even achieve the superiority of having a compact form factor of diffractive-based systems.
Simple : PinTILT™ Structure Enabled
Plastic-based PinMR™ lenses with PinTILT™ structure, made by cost-effective injection-molding processing, are up to 60% lighter, ten times more efficient, and a lot safer than competing AR optical systems, including DOE, HOE, and other reflective-based waveguides.
Compact : Structure
Combined with OLED microdisplays, without any bulky extra optics, LCoS panels, or light sources inside, LetinAR optical system has a best-in-class form factor for enabling a pair of truly natural-looking AR smartglasses.
Efficient : Longer Battery Use
The beauty of the PinTILT™ structure is its simplicity. Utilizing only two TIRs inside, while other competing structures use tons of them, enables much higher power/light efficiency up to ten times higher.
