D-ILA device is the heart of projectors that plays an impor tant role in projecting beautiful images. Device improvement continues to date – the third generation 0.69-inch native 4K D-ILA device improved the alignment control of liquid crystals and enhanced the flatness of image pixels to offer 1.5-times* the native contrast ratio compared to the Gen2 device. Additionally, improvements in the device manufacturing process have resulted in improved screen uniformity and enhanced image quality. *:DLA-NZ800 and DLA-RS3200 are 1.25-times.
Another essential aspect of projectors lies in their light source. The DLA-NZ series adopts JVC’s original laser light source “BLU-Escent Laser” to achieve exceptional peak brightness of 3,300 lumens on the DLA-NZ900 and 2,700 lumens on the DLA-NZ800, both with longevity of 20,000 hours. When compared to the first-generation laser projector*, the projectors’ brightness per effective wattage has improved 1.9-fold, which, as a result, also contributes to saving power through improved power efficiency.

The new Deep Black function has been added to Frame Adapt HDR, with a new algorithm to further subdue tones in dark areas to achieve more realistic darkness. This function maximizes the dynamic range of the new-generation 4K D-ILA devices and delivers images with more contrast than ever before. Scenes with light and dark shades such as nightscapes can be projected with greater realism.
The new D-ILA projector boasts the industry’s highest native contrast with the Gen3 0.69-inch 4K D-ILA device and wire-grid optical engine, however in combination with the dynamic laser light control, which analyzes the incoming video signal to automatically control the amount of outgoing laser light, a dynamic contrast level of ∞:1 (infinity to 1) can be achieved in scenes with pitch blackness by completely shutting off the light source. As a result, images brimming with reality that are closer to human perception can be produced. Likewise, the new algorithm enables laser control with greater precision to meet the user’s preferences.
The Frame Adapt HDR function, which uses a proprietary algorithm to instantaneously analyze the maximum brightness of any HDR10 content per scene or per frame and perform real-time tone mapping to optimal dynamic range for video projection, has evolved into the second generation (Gen2). The algorithm for tone mapping has been fully reexamined to achieve HDR images with higher definition. Furthermore, the proprietary algorithm for tone curve selection has also been improved to reproduce HDR images that are brighter, more colorful and have a wider dynamic range.
This D-ILA models support a variety of inputs including full 48Gbps 8K60p. By adopting LSIs developed with the latest technology, it is now possible to process four times the amount of information from input to D-ILA device instantly and correctly display 8K signals. As a result, users can enjoy stable high-quality 8K images at all times. Also, using 4K120p input with the Low Latency Mode further improves response to the player’s rapid operations, making it effective for displaying high frame-rate gaming content on large screens.
JVC’s proprietary 8K/e-shiftX, which is a combination of “e-shift technology” – a high-resolution display technology that doubles the resolution by shifting a pixel by 0.5 pixels in four directions up, down, left, and right – and “0.69-inch native 4K D-ILA devices” has made significant progress as the second generation 8K/e-shiftX. The latest version features JVC's newest 8K scaling engine that drastically improves the projector’s sharpness and detail across a wide range of content, including 8K (8192 x 4320 pixels) sources.
When it comes to reproducing the rich video information of HDR content, including the extended brightness range, BT.2020 wide color gamut and 10-bit gradation, rely on the new D-ILA projectors. Both models support all HDR formats including HDR10 for Blu-ray and streaming, HLG for broadcasting, and the HDR10+ with dynamic metadata compatibility. The projectors’ improvements for higher brightness and contrast have helped to achieve a wider dynamic range, allowing users to enjoy an immersive experience with HDR images full of reality.
The high-end DLA-NZ900 is equipped with an 18-element, 16-group all-glass lens featuring a full aluminium lens barrel. To project highresolution 8K images to every corner of the screen, the projector incorporates five ED lenses calibrated for differences in the R/G/B refractive index to reduce chromatic aberration and colour fringing when lens shift kicks in to deliver precise reproduction of 4K- or 8K-resolution projection.
