Optical Filters TRIZ Cases

Microlayer reflection bands block UV and blue light on-axis while preserving colored off-axis privacy viewing without black display effects.

Core-shell indium quantum dots balance sub-490 nm blue emission with high PLQY, improving color purity and reproducibility.

A plenoptic camera captures filtered light field images across multiple pupil positions in one shot, speeding HMD calibration while preserving accuracy.

Raised black matrix partitions between color filter regions block subpixel light leakage, improving color saturation and off-axis viewing.

A recessed phosphor layer with reflective and heat-radiation layers improves heat dissipation, preventing cracking, discoloration, and brightness loss.

A patterned photosensitive resist stays on the quantum dot layer as a mask, cutting removal steps and reducing layer damage.

Uneven phosphor surfaces and metal nanoantennas reduce total internal reflection, improving fluorescence extraction while narrowing emission angle.

A urethane-isocyanate primer bonds dissimilar film layers, cutting polarizing plate thickness while preserving peel strength and low haze.

By arranging wavelength-specific cells to match diffraction and sampling limits, this filter matrix improves image reconstruction consistency.

A standby-inserted front filter attenuates concentrated sunlight to protect the lens barrel from thermal damage without changing zoom position.

A low-index SiO2 hollow-filler layer and diffraction grating improve CMOS light focusing while suppressing refractive index rise and stains.

A metal-coordinated compound builds a strong network that suppresses pigment aggregation, improving heat resistance and spectral stability in color filter films.

High-index, low-liquidus glass disperses phosphor powder to limit scattering and devitrification while improving luminous efficiency.

Nested color filter layers and selective openings improve light emission efficiency while lowering color conversion substrate manufacturing cost.

Multiple thinner infrared filters replace one thick multilayer film to keep gas sensing precision while reducing warpage, chipping, and defects.

Rod- or fiber-filled optical film boosts hardness and creep resistance for foldable display covers without sacrificing light transmission.

Adjacent microstructures create phase-shifted interference to reduce wavelength dependency and control broadband far-infrared transmittance.

A thick multilayer optical filter limits center wavelength shift at high incidence angles, reducing cross-talk and measurement noise.

Integrating the lens and aperture in one coated glass element cuts alignment error, stray reflections, and sensor noise in compact optics.

Alternating semiconductor and dielectric layers absorb visible light while transmitting infrared light to reduce reflection and improve imaging quality.

Oxetane graft polymers help color filter films resist high-temperature shrinkage and cracking while improving pigment dispersibility and storage stability.
