Optical Filters TRIZ Cases
- High-Refractive-Index Light Collection Layer for Blue QE Improvement
A high-refractive-index light collection layer concentrates incident photons into underlying color filters to boost quantum efficiency.
- Transparent Photoresist Planarization for Display Resolution
A display panel uses transparent photoresist for both filters and planarization layers to ensure uniform thickness.
- Yellowish Photoresist Color Filter for LCD Brightness
A yellowish photoresist color filter increases optical transmittance through fluorescence.
- Indium Aluminum Quantum Dot Core-Shell Structure for Blue Light Emission
Replacing cadmium with indium and aluminum in the core reduces toxicity while maintaining high luminescence efficiency through precise shell thickness control.
- Quantum Dot Dispersion in Photosensitive Compositions
An acid group-containing copolymer stabilizes quantum dot dispersion in photoresists, preventing agglomeration during heat treatment.
- Four-Piece Infrared Lens for 3D Depth Detection
A four-piece infrared lens system uses specific refractive power distribution to achieve wide field of view and high resolution.
- Imaging Lens Protective Film Design for Compact Devices
Segmenting the lens system and adding a replaceable protective film resolves the contradiction between miniaturization and wide-angle performance reliability.
- Color Filter Transparent Electrode via Through Hole for Voltage Stability
A transparent metal layer connects to a substrate metal layer through a patterned through hole in the black matrix.
- Glazing Unit Optical Element with Perforated Shading
Perforated optical element between glass panes transmits light by angle of incidence while blocking direct solar radiation.
- Generic Stamp Fabrication for Structural Color Display Devices
A prefabricated generic stamp with micro-grating arrays creates structural color pixels through selective imprinting.
- Optical Filter with Near-Infrared Absorbing Dye for Incident Angle Stability
A composite optical filter combines dielectric multilayer films with a resin substrate containing a near-infrared absorbing dye to control spectral transmittance.
- Photonic Crystal Blue Light Filtering via Dielectric Stacking
Segmented dielectric layers selectively absorb harmful 420-470 nm blue radiation to protect eyes without reducing display brightness.
- Cyanine Dye Photosensitive Resin for Color Filter Luminance
A cyanine dye-based photosensitive resin composition achieves high luminance and contrast ratios through photopolymerization.
