Changing the structural design of the optical section from a conventional L-shape to a straight configuration helped to reduce light leakage and by combining this new structure with a highly efficient lamp, a brightness of 900 lumens was realised. What’s more, integrating JVC’s proprietary D-ILA device with the wire-grid optical engine provided very high contrast. And, by equipping the newly developed lens with a fixed aperture to help eliminate unnecessary light that reduces contrast levels, it was possible for the DLA-HD750 to achieve the industry’s highest native contrast ratio of 50,000:1*.
Thanks to enhanced brightness created by the extended white peak as well as the wider dynamic range for a deeper black, images are vivid and full of depth, making them perfectly suited for all types of content, including movies, music video as well as live concert and sports programs.
* As of September 2008; native contrast of 50,000:1 for home theatre projector class (JVC survey).
The newly developed high-performance 2x zoom lens with motorised focus features a large diameter, all-glass lens system with 17 elements in 15 groups that includes 2 ED lenses to project a full HD image with exceptional depth. And to display the deepest black possible, this new high-precision lens is also equipped with a 16-step lens aperture that allows adjustment of brightness according to user preferences and usage environment. What’s more, the high-precision lens also reduces chromatic aberration and colour bleeding significantly.
The DLA-HD750 features Colour Management that interpolates colours individually by R, G, B, C, Y, or M, in three separate axes of colour phase, chroma saturation, and brightness. Up to three customised colour settings can be stored for future use.
Manual adjustment of gamma curve is possible via an on-screen display, allowing the viewer to adjust projector luminance levels by either increasing contrast in scenes that are too dark or dimming washed-out scenes to ensure precise brightness levels suited to individual preferences. Up to three settings can be adjusted and stored for future use.
Both projectors incorporate the HQV Reon-VX video processor developed by Silicon Optix. To ensure excellent image reproduction, this processor features precision I/P conversion and scaling with full 10-bit 4:4:4 signal processing as well as an HQV noise reduction function to block mosquito noise.
