Ultra-high Contrast Optical Technology
Technical Overview
Our proprietary optical engine for D-ILA devices achieves an unparalleled level of native contrast, delivering exceptionally realistic image reproduction with D-ILA projectors.
D-ILA projectors are designed with a relentless focus on enhancing the native contrast inherent in the original image.
Through continuous refinement, we have succeeded in maximizing this capability to its limit.
When combined with dynamic contrast—which adjusts the light-source brightness for each scene—the result is extraordinary contrast performance.
From deep blacks to dazzling highlights, every element of the image emerges with exceptional realism and depth.
Technical Details
This technology integrates a proprietary D-ILA device with high-precision optical components, supported by advanced simulation and implementation technologies.
Its design thoroughly eliminates stray light from the optical system, achieving high native contrast.
• Wire-Grid Optical System
The optical system incorporates our proprietary high-performance wire-grid polarizer.
Its nanoscale metallic microstructure transmits only linear polarization in a specific direction, effectively blocking unwanted polarization components.
This suppresses elevated black levels caused by stray light within the optical system and dramatically enhances native contrast.
To maintain precise alignment of the wire-grid polarizer, we employ extremely accurate mechanical design and assembly technologies, along with high stability against heat and vibration.

• Polarization Compensation Technology
To suppress light leakage caused by the phase difference unique to D-ILA devices, we have developed a specially designed polarization compensation plate.
By optimizing polarization characteristics through advanced optical simulation, this technology precisely corrects the polarization state of light passing through the liquid-crystal layer, significantly reducing elevated black levels.
The integration of these sophisticated optical design and implementation technologies maximizes the native contrast of D-ILA devices, greatly enhancing gradation expression and image realism.
Polarization Compensation Technology
• Comprehensive Stray-Light Control through Optical Simulation
To maximize image purity, we perform detailed analysis of all light paths that could degrade image quality—such as minute scattered light generated at the edges of optical components or multiple reflections within the projection lens. Based on this analysis, we then implement thorough countermeasures against stray light across every optical element.
This meticulous attention to detail contributes to improved native contrast, deeper blacks, and an overwhelming sense of visual depth and realism.
