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.
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.
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.
BLU-Escent Laser can finely adjust the luminance according to the environment and preference using the Light Source Control by slider adjustment. There are a total of 101 (0 – 100) luminance control steps that can be used to make fine adjustments to match the target luminance in the environment and on the screen.
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.
The DLA-NZ800 is equipped with an 17-element, 15-group all-glass lens featuring a full aluminum lens barrel. To project high resolution 8K images to every corner of the screen.
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.
DML (Max Display Mastering Luminance) metadata, which represents the nit level of the professional monitor used to grade the movie to the director's standards, is used to set the dynamic range of the title for improved HDR tone mapping. On the DLA-NZ900/NZ800 series, both DML and MaxCLL values are used for the HDR levels.
The new Deep Black Tone Control 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.
Brightness of the projector screen varies depending on the screen size, gain, frequency of use, and Setting. JVC projectors intelligently adjust tone mapping so that the content can be viewed at the appropriate brightness by automatically analyzing the environment in which the projector is used, simply by entering the screen size and gain information under Theater Optimizer in the Frame Adapt HDR picture mode. This ensures reference picture quality at the appropriate brightness, suitable to each custom home theater environment.
Even when HDR content using a wide color gamut equivalent to BT.709 and DCI-P3 is projected on these projectors, the original cinema filter combined with the BLU-Escent Laser work together to reproduce rich colors, such as the gradations of the sky and ocean, the contrast of red roses, or a row of fresh green trees.
To reproduce SDR content with a narrow dynamic range in more saturated colors, conventional Natural mode has been improved to the new “Vivid” mode. This mode is excellent for projecting SDR animated works that are popular in streaming content and gaming CGs with greater vividness.
Clear Motion Drive*, which reduces afterimages, has improved its algorithm for compensation accuracy in the periphery of intersecting objects. Together with Motion Enhance technology, these projectors enable much smoother reproduction of images.
A 6-axis matrix of red, green, blue, cyan, magenta, and yellow enables the precise adjustment of hue, saturation, and intensity. Users can make adjustments suitable for the content as the projector allows precise management of colors.
Using an optical sensor and proprietary software*2, optimum calibration can be applied in just a few easy steps to match the changes in optical characteristics caused by the installation situation of the projector. Auto-Calibration optimizes all essential elements found in the image, including color balance, gamma characteristics, color space, and color tracking. In the past, multiple calibrations were required, but now it's possible to complete the calibration with a single calibration.
*2: An optical sensor and proprietary software, which is downloadable from JVC website, are required to perform auto calibration function. Refer to the JVC website for details.
Today's diversified video signals require settings that match the input signals for viewing at an appropriate picture quality. The latest projectors from JVC provide various functions and menus for easy, optimized use of the settings. To name a few, there is a menu for Content Type, a function to automatically switch Color Profile, and a function to set Auto Pic. Mode Select. Content Type menu: Use this menu to select the best "picture quality mode" for the input video without worrying about complicated manual gamma and gamut settings. Automatic Color Profile Switching function: Use this function to automatically switch to the optimal color profile according to the color gamut information of the video signal, eliminating the need for manual switching. Auto Pic. Mode Select: Use this function to set the "Picture Mode" corresponding to each input signal (SDR, 3D, HDR10, and HLG).
These projectors are equipped with Installation Mode that allows users to centrally manage settings related to installation in order to enjoy projected video optimized for each environment. As shown in the graphical interface, eight settings for Lens Control, Pixel Adjustment, Mask, Anamorphic on or off, Screen Setting, Installation Style, Keystone, and Aspect can be adjusted. Additionally, ten different mode settings can be stored in memory and named as desired. Installation modes stored in memory for various environments can be called up immediately.
Screen Adjustment Mode is one of the nine Installation Modes described above. When the user selects a setting that best suits the screen being used from the Screen Adjustment Mode settings, the projector adjusts the image with natural color balance to match the screen. The mode is compatible with the latest models offered by the world's major screen manufacturers.
A 2.35:1 aspect ratio for wide cinematic films can be enjoyed by combining the projector with a third-party anamorphic lens to create dynamic picture reproduction just as can be seen in a movie theater.
The USB Back-up function can save and write settings on the main unit menu to a third-party USB flash drive all at once. It is important to save adjustments made by an installer or specialist, or to undo unintended adjustments made by children or family members.
