New flagship 4K home theater projector wide color gamut, HDR compatible

JVC unveiled at CEDIA a new flagship home-theater projector driven by a laser light source and delivering wide color gamut and high dynamic range (HDR) content.

The DLA-RS4500 features a new JVC-developed native 4K D-ILA device and a laser light source with dynamic light control to deliver high brightness and high contrast images. The 4,096 by 2,160 4K D-ILA device is driven by the company’s proprietary Blu-Escent laser phosphor light source, achieving a brightness level of 3,000 lumens with more than 20,000 hours of operational life, the company said. It narrows the pixel gap by 31 percent from JVC's previous models.

By using both vertical orientation technology and planarization technique, scattering and light diffraction have been decreased, which enhances contrast. The result, JVC said, is a smooth, detailed image with no visible pixel structure, even when using large screens. The projector uses three 4K D-ILA devices, one each for red, green and blue.

The Blu-Escent laser light source employs six banks of eight laser diodes to achieve its high brightness levels, and a stationary emissive phosphor, which reduces mechanical noise and enhances reliability. The light source also allows the projector to control laser output dynamically, adjusting output to achieve brighter whites, deep darks and brilliant colors, JVC said.

Developed in conjunction with the new 4K D-ILA device was a new 18-element, 16-group all-glass lens with full aluminum lens barrel. A new 100mm diameter lens is used for best light efficiency and to project 4K resolution to the corners of the screen. This compares with 65mm diameter designs used in other JVC projectors. By adopting five anomalous dispersion lenses the projector is said to be able to reduce chromatic aberration and color fringing.

When the projector detects an HDR signal, it automatically selects the correct picture mode preset based on HDR10. The DLA-RS4500 also offers Hybrid Log-Gamma, a new HDR standard for broadcasts and streaming services.

The DLA-RS4500 features an all-new cosmetic design, with a symmetrical cabinet that combines aluminum and matte black paint, meant to reduce reflections. The center-mounted lens is set off from the black body by a gold alumite ring.

For cooling, the rear intake/front exhaust fan adapts to the installation environment to maximize its effectiveness and it employs a professional level air filter.

JVC’s Multiple Pixel Control employs a new algorithm optimized to produce detailed images even when converted from FullHD images.

It also features JVC’s blur-reduction technology, Clear Motion Drive, which is compatible with 4K60p (4:4:4), and Motion Enhance, which is engineered to minimize motion blur by optimizing the D-ILA driver.

The JVC DLA-RS4500 Reference-series projector will be available in December for $35,000.
