OMIS White 2.2 Screen
Gain-2.2 White Screen for Reduced RGB Speckling
Nearly 3× the Viewing Angle of Conventional Silver Screens
Overview
Ultra-Low Speckle
3.5% ultra-low speckle contrast maximizes the brightness, contrast, and image uniformity of RGB lasers, ensuring accurate color reproduction
Wide Viewing Angle
Supports 160° viewing and wide-angle projection
Cleanable Surface
Anti-oil and Anti-stain: Resists permanent markers with an easy-to-clean finish. Resistant to common spills and fruit juice
High Brightness Uniformity
Reduces hotspots to ensure highly uniform light distribution
High Screen Gain
2.2-gain optical-grade white screen
Anti-Ambient Light Interference
Ambient occlusion rate of 55%, effectively minimizing stray light interference
Stable Performance
Exceptionally long service life with zero yellowing over time
Technical Principles
Utilizing Stacked Multi-layer Microlens Array (MLA) technology and multi-stage particle reflection pathways, the screen effectively destabilizes laser coherence to suppress speckle at its source.
It achieves a precision-engineered synergy between high gain, speckle mitigation, luminance uniformity, and color fidelity.
Optical Micro-Mirror Array: Core Technology
1. Professional Optical Design:
Features micrometer-scale optical micro-mirror structures, engineered with precision optical modeling and ray-tracing simulations to accurately control beam shape and propagation paths. Widely applied in imaging and beam-shaping applications.
2. Precise Light-Field Control:
Utilizes a microlens array randomly distributed across a spherical reflective structure to enable controlled, continuous, uniform, and high-gain diffuse reflection, optimizing image quality and brightness consistency.
3. Complex Light-Field Manipulation:
Employs parallel micro-optical modulation to homogenize light beams for improved illumination uniformity and simultaneously enhances imaging performance through extended depth of field and higher resolution.
4. Mass-Scale Micro-Mirror Industrialization:
Mastered the design and mass production of large-format optical films embedded with ultra-high-density microlens arrays. A proprietary manufacturing ecosystem, supported by in-house developed equipment, ensures a closed-loop, end-to-end production capability.
