JVC has announced a new Home Theatre Projector using JVC original developed native 4K D-ILA device, "DLA-Z1" which is available from Invision UK.
The demand for 4K home theatre projector is increasing in accordance to the increase of 4K contents like UHD Blu-ray or OTT distribution. Since 2011, JVC has been popular for developing projectors with “e-shift” technology to realize 4K resolution images. In 2016, for the customers to enjoy the new 4K and HDR images (which could be said to be a visual revolution), new contents, new source equipment, new transmission standards (HDMI/HDCP) has become available at once, and many requests are heard from the customers for a product which can fully project the 4K/HDR images. Therefore, in the pursuit of realising further high quality images, JVC will introduce the new High-end Flagship model “DLA-Z1” loaded with the newly developed 4K ”D-ILA” devices and Laser light source “Blu-Escent”. “DLA-Z1”, gathering the High definition, high quality technologies which has been developed over many years by JVC, will promise an unforgettable Home Theatre experience.
This new projector includes a Laser light source “Blu-Escent”, realising a brightness of 3,000lm which also has dynamic light source control, unique for laser, plus 20,000 hours operational life time. Additionally a high brightness, high quality, and vivid 4K picture can be produced thanks to the new lens dedicated for 4K and the new Cinema Filter with wide colour gamut.
1. Newly developed Native 4K “D-ILA “ device
JVC first developed its Native 4K D-ILA device in the year 2000. Since then JVC has continuously developed this technology, 1.7inch device in 2004, 1.27inch device in 2007, being one of the leading companies in the high definition video field.
The new D-ILA device developed this time has narrowed the pixel gap by 31% against former devices to 3.8㎛, realising high quality 4K (4096x2160 pixel) picture with the World’s smallest 0.69inch device. Further, by using both vertical orientation technology and planarisation technique, unnecessary scattering and diffraction of light has been decreased to realise high contrast ratio. DLA-Z1 uses three of these 4K D-ILA devices, each device dedicated for the colours Red, Green and Blue.
As a result a smooth, detailed picture without the lattice being seen, can be produced even when using large screen sizes.
2. High brightness and Long life brought by Laser light source “Blu-Escent”
The light source will be JVC original Laser technology “Blu-Escent” using a Blue Laser diode. This will mean high brightness of 3,000lm and 20,000 hours long life can coexist. The improvement of brightness will make compatibility to large size screens over 200inches, and raise the peak brightness on HDR picture, which will bring depth to the picture like you have never experienced on home theatres before.
3. High definition, ∞:1 contrast ratio realised by Dynamic Light Source Control
Using the Laser Diode as the light source, light output can be controlled instantly. This means brightness control can be made without delays compared to the conventional mechanical adjustment (lens aperture). DLA-Z1 can control the laser output accordingly to the scene’s brightness, which creates picture that is close to the human perception. Also by controlling the laser output when switching scenes or during signal identifications, contrast ratio of ∞:1 has been realised.
4. Vivid Images created from wide Colour Gamut
The combination of Laser light source and new Cinema Filter can obtain wide colour gamut of 100% DCI P3 and over 80% coverage of BT.2020. The gradation of sky or sea, the crimson red of a rose, the fresh green of trees can be reproduced vividly like never before. It can realize a beautiful picture even when compared to movie theatres for UHD Blu-ray contents, by expressing the various colours contained in the content utilising the wide colour gamut.
5. New High Resolution Lens dedicated for 4K
Together with the “4K D-ILA” devices, a new 16 group 18 sheets all glass lens and full aluminium lens barrel has been developed. The diameter of the lens is 100mm compared to conventional 65mm, in order to project the 4K resolution to every corner of the screen whilst keeping a wide shift range of 100% vertical, 43% horizontal shift. In addition, adopting five anomalous dispersion lenses in accordance to the different refractive index of R/G/B light, the chromatic aberration and colour fringing when shifted can be minimised, resulting in precise projection of 4K resolution graphics.
6. HDR (High Dynamic Range) Compatibility
HDR contents like UHD Blu-ray, are contents with extended brightness range, 10bit gradation, wide BT.2020 colour gamut, which demand high specifications to the display equipment. The DLA-Z1, having high contrast ratio with 80% BT.2020 coverage, and dynamic light source control together with high brightness, can let you enjoy the full merit of HDR images.
7. New Design intended for Top-end model
Symmetrical design body with high quality, hairline finished aluminium centre part to put accent. Matt black paint is applied to reduce reflections in pitch black theatre rooms. Inside the lens ring, that accentuates the large diameter lens, is a gold alumite ring which adds casual luxury to the model. Not only that, the rear intake/front exhaust can flexibly adapt to the various environments of installations, and further to ensure long term usages, it employs professional level air filter which can withstand sever conditions.
