DDS® Directional Display Screen - Rear Projection

POC’s DDS rear projection screens feature fully randomized (non-periodic) micron structures that are very suitable for the high-resolution and directional requirements of LCD projection, digital projection, high definition systems, LCD workstations and LED displays. The patented holographic master recording process enables a wide range of viewing angles and the precise placement of photons in the viewing area. These surface relief patterns maximize the light availability for bright, high-resolution viewing.

DDS® Advantages:

  • High-resolution/high-gain screens
  • Custom viewing angles (0.2º to 100º)
  • Low back-scattering for high transmission
  • Randomized (non-periodic) structures eliminate moiré fringes and chromatic aberration.
  • Minimal effects to polarization. Acrylic substrate offers low birefringence.
  • Can be combined with polarizer, Fresnel, prismatic structures, lenses and contrast correcting material.
  • A second front surface diffusing angle reduces glare, scintillation and specular reflection.
