Optical Filters TRIZ Cases
- Stepped Metal Sensing Structures for Analyte Detection
A stepped metal layer and controlled gap improve wavelength-shift detection for more sensitive analyte sensing in SPR structures.
- Dynamic Extraocular Filtering for Color Contrast Without Restriction
Rapidly switching an active filter selectively removes wavelengths for contrast, then restores full-spectrum transmission so all colors remain visible.
- Six-Primary Color Display Architecture for Wide-Gamut Reproduction
Six independently controlled RGB-CMY channels expand gamut, reduce viewer metameric errors, and lower power use.
- Fluorine-Free Cu-Mo Phosphate Optical Filter Glass for Visible/NIR Filtering
Fluorine-free Cu-Mo phosphate glass preserves blue-light transmittance while absorbing near-infrared light for imaging filters.
- Thermal-Isolative Optical Lens With Near-Infrared Filtering
Segmented absorbent regions block violet, UV, red, and near-infrared light while preserving visible transmission and reducing IR-heat energy.
- Photosensitive resin composition, photosensitive resin film, photosensitive dry film, pattern forming method, and light-emitting element
Silane coupling agents anchor quantum dots in cured photosensitive resin, supporting fine micro-LED patterns while preserving luminous properties.
- Metal-Dielectric Phase Shifter for Chromatic Aberration Reduction
Alternating metal and dielectric layers give the phase-shifting device a substantially constant refractive index, reducing chromatic aberration across broad optical bands.
- Removable Microscope Light Shielding for Fluorescence Contrast
Ambient light can lower fluorescence image contrast; a removable condenser-mounted shield blocks it while enabling easy bright-field switching.
- Color Conversion Panel Alignment Patterns for Stitch Error Control
Alignment patterns and openings monitor boundary stitch errors, reducing gray-scale differences and visible stitch stains.
- Light-Emitting Device With Shifted Microlenses for Optical Efficiency
Shifted microlenses refract light from each emission region toward front and oblique directions, improving optical-system utilization and reducing power consumption.
- Solvent-Free Quantum Dot Composition for Stable Ink-Jetting
Specific monomer linking groups keep quantum dots dispersed without excessive viscosity, supporting stable ink ejection and reducing nozzle clogging.
- Color Conversion Panel With Multilayer SiON Capping for Stain Control
Multilayer SiON capping addresses stain generation while supporting color conversion efficiency in the display panel.
- Neutral-Black Optical Glass Composition for LiDAR Windows
A balanced glass composition limits visible transmission while preserving NIR passage and a neutral black appearance for LiDAR optics.
- Folded-Optics Camera Module for Telephoto Imaging in Compact Devices
Prisms redirect light through a folded path, fitting telephoto imaging and optical stabilization into space-limited devices.
- Electron-Withdrawing Purple Dye Photoresist for Eyesafe Displays
Electron-withdrawing purple dye in a blue color resist helps protect the retina while maintaining display color gamut and transmittance.
- AlN–SiO2–Si:H Optical Interference Filters for Singulation Durability
A SiO2 layer between AlN and Si:H protects interfaces during singulation, limiting chipping and delamination in optical filters.
