Planar/Plate-Like Light Guides TRIZ Cases
- Blind-Spot Optical Member With Rough Prism Light Shielding
A roughened prism light-shielding surface scatters and absorbs stray light, improving blind-spot visibility through the optical member.
- Holographic Waveguide Rear-Seat Display for Comfortable Viewing Distance
A holographic optical waveguide projects a larger virtual image farther away, easing rear-seat eye strain without adding display bulk.
- Slotted Waveguide Photodetector for Bandwidth-Responsivity Tradeoff
Segmented slot waveguides adjoined to a photodetector improve coupling and responsivity while preserving bandwidth in a compact chip structure.
- Light Guide Panel Incident Surface Geometry for Higher Light Extraction
A concave incident surface and inclined bottom faces redirect and reflect light to raise output luminance without thickening the light guide panel.
- Light Guide Deadfront Structure for Seamless Curved Vehicle Displays
A light guide and extraction layer create hidden off-state display graphics while preserving high-contrast visibility on curved vehicle surfaces.
- Light Guide Exit Structure for Moire-Suppressed Optical Members
Step-shaped reflective surfaces and prism parts alter reflected light pitch to suppress moire while preserving blind spot scene visibility.
- Vehicle Roof Glass Panel With Integrated Light-Coupling Prisms
Rectangular prism light couplers bonded to laminated roof glass improve cabin illumination without adding extra glass layers, weight, or assembly complexity.
- Switchable Optical Element for Display Privacy Without Light Loss
Alternating refractive-index regions and switchable opaque layers narrow display viewing angles for privacy mode while preserving brightness.
- Silicone Lens Array and Lightguide for Solar Power Concentration
Silicone lens arrays and shaped lightguides replace glass concentrators to cut cost and complexity while maintaining high solar transmittance.
- Vehicle Mirror Light Guide With Scattering Particles for Uniform Luminance
Embedded scattering particles in a vehicle mirror light guide improve luminance uniformity and reduce reliance on prisms or multiple light sources.
- Rearview Mirror Bezel HMI With Hidden Icons and ToF Gesture Sensing
A reflective mirror bezel hides touch icons until lit, using ToF sensing and guided light to keep gesture control visible and precise.
- Light Guide Deadfront Structure for Hidden Display Edges
A light guide and extraction layer hide display edges when off, then reveal clear graphics through curved cover glass when illuminated.
- HOE Wide-Angle Camera Optics With One Sensor and Low Distortion
Holographic optical elements split and deflect incident light so one image sensor can capture a wide field of view with lower distortion and cost.
