D-ILA device ensures remarkably smooth picture reproduction
The D-ILA panel originally developed by JVC has a high aperture ratio as it is designed with exceptionally narrow gaps between the pixel elements. This design effectively eliminates the “screen-door” effect as the pixel elements do not stand out, resulting in reproduced images that are smooth and silky.
Exceptionally high contrast ratio of 70,000:1*
“Native contrast” refers to the contrast ratio figure of a projector that is not dependent on iris control. The DLA-HD990 boasts an exceptionally high native contrast ratio of 70,000:1 to achieve both extended white peak and deeper blacks within scenes simultaneously, ensuring image reproduction that is vivid and full of depth. This performance helps to make the DLA-HD990 perfectly suited for viewing diverse content, such as movies and music videos as well as live concert performances and sports programmes.

The true potential of the native contrast ratio
D-ILA method realises an exceptionally high contrast ratio
JVC's proprietary D-ILA device achieves an exceptionally high native contrast ratio by combining extreme planarization technology, which reduces stray light to an absolute minimum, and an optical engine with wire-grid polarisers.
Extreme planarization technology
The D-ILA device features high-planarization technology that reduces stray light caused by diffraction to an absolute minimum, helping to decrease light leakage and loss from the liquid crystal layer itself to ensure an exceptionally high contrast ratio.
Optical engine with wire-grid polarisers
The wire-grid design employed by JVC’s optical engine uses an inorganic reflective polarising plate made from a glass substrate on the surface of which are formed an array of ultra-fine aluminium ribs. Because the polarising plate is ideally set at the optimum angle to reflect polarised light, it reduces the amount of stray light reaching the lens to an absolute minimum. The combination of this polariser with the 0.7-inch full HD D-ILA device allows an exceptionally high native contrast ratio to be achieved.
Clear Motion Drive for clear reproduction of scenes with rapid movement
Clear Motion Drive technology successfully generates an accurate intermediate frame even for scenes with rapid movement by employing JVC’s original high-precision interpolation algorithm that strengthens the precision of picture-character detection. When the video signal source is 50/60 fps broadcasting, viewers can enjoy smoother and clearer images with reduced motion blurring thanks to this unique interpolation technique that optimises the number of frames.
Advanced video processor
At the core of its video circuitry, the projector incorporates the HQV Reon-VX video processor developed by Silicon Optix, which features precision I/P conversion and scaling to achieve exquisite video reproduction of the highest quality.
High-performance 2x motorised zoom lens
In order to reproduce high-definition images more faithfully, the high-performance 2x zoom lens with motorised focus features a large-diameter, all-glass lens system with 17 elements in 15 groups that includes ED lenses. This lens system also reduces chromatic aberration and colour bleeding significantly to project images with precise details and exceptional depth. What’s more, the lens aperture enables adjustment of brightness in 16 steps* to display the deepest black possible.
