Diffusing Elements TRIZ Cases

Irregular concave depths suppress diffraction effects while maintaining high light use efficiency in projector optical devices.

Composite resin coatings resolve adhesion trade-offs between solvent-free prism patterns and polyester films in LCD backlight units.

Controlled hard coat surface roughness parameters suppress interference fringes and curls without thick impregnated layers, reducing production costs.

Acute angle lattice structures on light flux control members suppress internal reflection and bright spots when components are positioned closely.

A compact integrating volume with a non-spherical cavity homogenizes laser beam intensity through semi-diffuse surface scattering.

A hologram recording medium diffracts coherent light beams to reproduce a scattering plate image for controlled illumination.

A light-path changing layer with optical structures redirects reflected light in display windows.

Composite antireflection films reduce ghosts and flare in optical systems by maintaining mechanical strength while achieving broadband low reflectance.

Tapered slots in the ring-shaped adhesive layer weaken stray light to prevent abnormal refraction and reflection phenomena.

Inwardly facing protrusions in the light collimator redirect scattered rays to photodetectors, restoring measurement precision lost during diffusion.
