can still continue to output a significant amount of light (Figure 4).
During its long service life, in the unlikely event that the laser itself suffers an outage, our
professional service team can simply swap out the entire LD (Laser Diode) engine for a new one,
without major adjustment or recalibration. Overall, Wolf Cinema guarantees that the illumination
system – the BLU-Escent laser modules and phosphor wheel – will last over 20,000 hours [to 50%
brightness] in the most demanding home theater environments.
V4K™ 3840 x 2160 Resolution
Resolution is also an important factor in today’s projector choices. The DLD-380FD boasts the
remarkable V4K™ on screen imaging technology [also known as “e-shift”]. Originally co-developed
by Japan's NHK Engineering and the Victor Company of Japan [JVC], this technology implementation
by Wolf Cinema delivers an image with 4 times the pixel density of standard 1920 x 1080 sources.
The original SD or HD signal is first processed with an advanced imaging algorithm to improve
edge transitions, eliminates aliasing and stair-stepping, and increase contrast level performance
within each video frame. Each frame is then temporally separated into two sub-frames [at 1920 x
1080 pixels each] and projected through the D-ILA engine and the separate V4K™processing panel.
This panel utilizes a property of liquid crystals called birefringence and can rapidly switch between
straight light and refracted light by 0.5 pixel, shifted both vertically and horizontally. New “sub
pixels” are thus generated based on this process and a true 3840 x 2160 video frame is created.
Amazingly this process has no moving parts and results in a smooth, film-like image with minimal
visible pixel structure. [Figure 5]
