Diffusing Elements TRIZ Cases
- Light Flux Controlling Member for LED Light Leakage Prevention
A light flux controlling member with segmented incidence surfaces directs emitted light laterally to prevent vertical leakage.
- Biomass Polyester Optical Film Minimized Rainbow Effects
Optical film incorporates biomass-derived polyester to minimize rainbow interference patterns while maintaining mechanical strength.
- Light Diffusion Film Using Ultra-Fine High Refractive Index Particles
Ultra-fine inorganic particles with a refractive index of 2.00 or more improve light diffusibility and shape-hiding in thin films.
- Transmissive Display Depolarization for Polarized Outside Light
A depolarization member cancels outside light polarization, preventing luminance deterioration and coloring in transmissive displays.
- Light Control Member with Enlarged Shielding Layer for Adhesiveness
An enlarged shielding layer extends into the thickness direction to increase bonding area, resolving the trade-off between coverage and adhesiveness.
- Semi-cylindrical Illuminator for 180-Degree Uniform Light Distribution
A semi-cylindrical illuminator uses a conical internal structure to internally reflect light beams across a wide angle.
- Symmetric Diffusion Film for Touchscreen Luminance Mura
A symmetric diffusion film with mixed refractive indices diffuses light to eliminate off-axis luminance mura caused by sensing electrode interference.
- Salt Optic Moisture Barrier Coatings for Infrared
Multilayer coatings on salt optics prevent humidity erosion, maintaining optical performance in high-moisture environments.
- Projector Polarization Conversion for Illuminance Uniformity
A projector uses a birefringence element to convert linearly polarized light into circular or elliptical polarization before diffusion.
- Optical Sheet Composite Structure Eliminates Newton's Rings
Superimposed convex shapes eliminate reflective Newton's rings while maintaining brightness by optimizing surface roughness and diffusion area.
- Anisotropic Diffusion Sheet for Laser Illumination Uniformity
A two-dimensional anisotropic diffusion sheet adjusts laser beam divergence to create a circular light spot.
- Optical Stack With Embedded Diffuse Surface for IR Sensor Protection
An optical stack embeds a bumpy diffuse surface between index-matched layers to hide sensors while maintaining high light transmission.
- Optical Assembly Adhesive Hydrophilic-Hydrophobic Balance
Hydrophilic and hydrophobic adhesive parameters bond optical film microstructures, resolving the trade-off between high adhesive force and optical gain.
- Wavelength-Converting Element Inorganic Binder Thermal Management
An inorganic binder cures at lower temperatures to reduce pores in the diffuse reflection layer, improving reflectivity and brightness.
- Viewing Angle Diffusion Film Staggered Refractive Protrusions
Staggered refractive protrusions disrupt periodic superposition to eliminate Moire patterns while maintaining high light transmittance.
