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. 

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.

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 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.

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.

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.
