Display Technology Coating Architecture

ULR polarizer coating replaces Japanese imports

Transmission 97.0%, haze 0.41% (vs 0.68% incumbent Japanese 3-layer AR supplier), 4H hardness, zero curl.

500M m²/yr Chinese polarizer market

Enables domestic production independence.

Anti-static hardcoat on bottom polarizer

Surface resistivity below 10⁹ ohm/sq, combined HC+AS in single layer, prevents dust attraction during assembly.

Single supplier for full AR+AF+HC stack

HRI (n=1.65-1.95) + LRI (n=1.16-1.40) multi-layer AR achieving R<0.5% broadband. Anti-smudge topcoat with WCA >100° survives 2,000 steel wool cycles.

PFAS-free anti-smudge performance

Functionalized hollow silica nanoparticles replace fluorinated treatments. Compliant with EU REACH universal PFAS restriction proposal.

Foldable: 20x better fold endurance than sputtered

Wet-coated AR on flexible CPI survives >200k folds where sputtered coatings crack at <10k cycles.

Only wet-coated solution surviving >200k folds

Validated at 1.5R radius. Sputtered AR cracks at <10k cycles. This is a 20x durability advantage that enables next-gen foldable form factors.

Single-layer multi-function: AS + AF + HC

107-series hardcoat combines anti-smudge (WCA >95° after 2,000 steel wool), anti-static, and 4H+ hardness in one coating step.

R2R compatible formulation

UV-curable at 35 wt% solids, compatible with continuous roll-to-roll manufacturing on CPI and TPI substrates.

Graded RI from n=1.40 to n=2.00

Solves the GaN-to-air light extraction problem. Sequence of thin coatings creates a gradual RI transition rather than an abrupt interface.

30-40% efficiency gain

Validated improvement in external quantum efficiency. Translates directly to lower power consumption or higher brightness at same power.

No other single supplier covers this full RI range

Nanoparticle dispersions tunable from 1.16 to 2.00+, compatible with pixel-level deposition. One qualification process instead of multiple vendors.

Uniform light distribution per zone

Local dimming zones need uniform extraction without hot spots. Kriya coatings on diffuser plates optimize angular light distribution across each zone.

Combined with LCD top coatings

Full LCD stack (see Section 01 above) sits on top. Kriya coatings appear in both the backlight diffuser and the LCD panel layers, providing integrated optical design.

HRI outcoupling layer (n=1.7-1.9)

Positioned between OLED emissive layers and substrate. Bridges the refractive index gap to increase external quantum efficiency. HRI nanoparticles provide the required optical density.

Cover glass AR at 93.8%+ transmission

Multi-layer AR on the viewing surface maximizes the photons that reach the viewer. PFAS-free anti-smudge topcoat maintains optical clarity.

Both internal and external efficiency

Unique positioning: Kriya addresses both the internal extraction (outcoupling) and external viewing (AR) efficiency from one materials platform.

Anti-ghosting AR eliminates double-image

Tuned to suppress the secondary reflection from the inner windshield surface that causes the ghost image offset from the primary HUD projection.

Tunable to HUD projection wavelength

AR stack thickness and RI optimized for specific projector wavelengths (typically green 520-560 nm for maximum eye sensitivity).

Wet-coated for automotive scale

Compatible with existing automotive glass coating lines. No vacuum deposition required. HUD market projected at $9B* by 2030.

Complete waveguide materials system from one supplier

HRI core (n=1.65-1.85), LRI cladding (n=1.16-1.40), 100% solids for nanostructure replication, and AR coatings for both surfaces. Single qualification process.

R2R compatible

UV-curable formulations at 100% solids enable nanoimprint lithography on continuous roll stock. Eliminates the wafer-level processing bottleneck that limits current production scale.

NIL-compatible 100% solids (zero shrinkage)

Critical for nanostructure fidelity in diffraction gratings. No solvent evaporation means no feature distortion during cure. Viscosity 10-1,000 cP for process flexibility.
