jvc_dila_beamer_roadmapWie bereits aus der alten Roadmap zu erkennen ist, war das (vorläufige) Ziel von JVC ein 2x4=8K-LCOS-Beamer.

Jetzt erfahren wir, dass JVC die Technik für eine Beamer mit 35 Megapixeln entwickelt.

JVC entwickelt einen Chip mit LCoS-Technik, welcher es auf eine Auflösung von rund 35 Megapixeln bringen soll. Der LCOS-Chip (Liquid Crystal on Silicon) misst nur 1,75 Zoll im Durchmesser. Super Hi-Vision 8K4K erreicht 17fach höhere Auflösung als Full-HD.

jvc_8k4k_chipDie Auflösung von 8.192 x 4.320 Pixel ergibt ein Seitenverhältnis von 17:9. Der Abstand zwischen den Pixeln liegt bei 0,24 Mikrometern, die Füllrate der Sensoroberfläche damit bei über 90 Prozent. Das Kontrastverhältnis beziffert JVC mit 20.000:1 und die Reaktionszeit mit 4,5 Millisekunden.

JVC hat mit der LCoS-Technik, die das Unternehmen unter dem Namen "D-ILA" (Direct-Drive Image Light Amplifier) vermarktet, bereits 2003 ein Microdisplay vorgestellt, das es auf eine Auflösung von 4K2K (3.840 x 2.048 Pixel) bringt. Im Juni 2007 konnte JVC ein 1,27 Zoll großes D-ILA mit 4K2K vorstellen, das im Februar 2008 in Form des Projektors DLA-SH4K auf den Markt kam.

Hier die Seiten des japanischen Fernsehens NHK, welcher sich schon länger sich über den HDTV-Standard Gedanken macht. www.HDAV-News.de vom 17.April 2007

For Immediate Release: May 2, 2008
World’s highest*1 35 megapixel pixel count:

More than 17 times Full High-Definition, JVC Develops 1.75-inch 8K4K D-ILA Device

~ World's first*1 single display device achieving Super Hi-Vision*2 (33 megapixels)~
Victor Company of Japan, Ltd. (JVC) announces a new addition to its lineup of proprietary
D-ILA (Direct-Drive Image Light Amplifier) high-definition reflective liquid crystal devices for
projectors. The newly developed 1.75-inch 8K4K D-ILA device has the world's largest number of
pixels*1 and is able to display images of approximately 35 megapixels (8192 x 4320 pixels), the
equivalent of more than 17 times the level of Full High-Definition. This means that a single
display device can now produce Super Hi-Vision images and can display images with the highest
number of pixels currently defined under international standards.
*1 As a projection-type display device, as of May 2, 2008.
*2 Super Hi-Vision is a TV broadcasting service currently under development at NHK; a single image has
approximately 33 megapixels (7680 x 4320 pixels), with 60 frame/second sequential scanning and 22.2
multichannel sound. Image format is international standard ITU-R BT.1769, SMPTE 2036. Diagonal size is
1.67 inches at Super Hi-Vision standard pixel dimensions of 7680 x 4320.
After JVC developed the initial 7.86-megapixel (3840 x 2048 pixels) 4K2K D-ILA device in the
summer of 2003, it subsequently further evolved the technology for highly realistic, high-definition
images through a range of test viewings and verification testing, resulting in the development of
JVC’s first commercial 4K2K D-ILA device (1.7-inch device size, 5,000:1 device contrast ratio)
and the 4K2K D-ILA projector incorporating that device in September 2004.
In June 2007 JVC developed a 1.27-inch 4K2K D-ILA device that was the world's smallest
device of its kind, having a 6.8μm pixel pitch and 4096 x 2400 pixels, and in February 2008 it
began marketing a newly commercialized professional D-ILA projector, DLA-SH4K, incorporating
that device.
Through the development of a new production process and new pixel structure for even finer
pixels, JVC has now succeeded in developing the 1.75-inch 8K4K D-ILA device, the world's first
device to achieve real Super Hi-Vision definition level. The new device has approximately 50%
higher density in its ratio of area per pixel as compared to the 1.27-inch 4K2K D-ILA device,
which was originally the world's smallest 4K device. Furthermore, the new device has achieved a
video display of approximately 35 megapixels, the world's highest pixel counts*1, while continuing
to provide the D-ILA series' characteristics such as “high-quality images without a distracting
pixel structure”, “high light availability”, and “high contrast ratio”.

Features of New 1.75-inch 8K4K D-ILA Device
1. The 4.8μm pixel pitch fine pixel technology makes possible a device that is just 1.75 inches
on the diagonal while achieving ultra-high-definition images of 35 megapixels (8192 x 4320
pixels), the highest pixel count in the world.
2. The device resolution of 8192 horizontal x 4320 vertical dots is fully compatible with the
Super Hi-Vision standard (7680 x 4320 pixels) being promoted by NHK as next-generation
broadcast technology. Able to display ultra-high-definition images that are 17 times Full
High-Definition and 4 times conventional 4K2K (the DCI 4K digital cinema standard), the
new device can be used for a wide range of leading-edge ultra-high-definition imaging
3. The 0.24μm gap between pixels achieves a high aperture of 90% or higher surface devoted
to image, while maintaining ultra-high resolution. In addition, technology adopted to reduce
disorder caused by liquid crystal orientation has made it possible to limit extraneous light
such as scattered and diffracted light from reflective surfaces, with the end result being a
high contrast ratio of 20,000:1 for device contrast.
4. By applying the same inorganic alignment layer used on previous D-ILA devices, the
tradition of long life and high durability is successfully maintained.
5. JVC's extensive production experience and technology made it possible to achieve both
reduced liquid crystal cell gaps and high image uniformity, with the goal being to achieve
quick liquid crystal response.
6. It is possible to create a device driver for the ultra-high-bandwidth signal of 8K4K resolution
by adopting a new package structure that accommodates the optimized internal driver
design and the increased number of drive signal line inputs.jvc_dila_lcos-groese

Development Background
In 1996, JVC embarked on the development of ultra-high-definition image systems to
surpass High-Vision definition. The company developed the first 7.86-megapixel (3840 X 2048
pixels) 4K2K D-ILA device in summer 2003 and began supplying projectors containing this
device for research applications in March 2001.
In June 2007, JVC developed a 1.27-inch 4K2K D-ILA device having a 6.8μm pixel pitch and
4096 x 2400 pixels, and in February 2008 it began marketing a newly commercialized
professional D-ILA projector, DLA-SH4K, incorporating that device.
While pursuing these development activities, JVC has also been contributing to research
and development of ultra-high-definition image systems domestically and internationally
through cooperation with the standardization of the Digital Cinema Initiative (DCI) 4K2K
specifications and by providing projectors for the Super Hi-Vision 8K4K system being
developed by NHK.
In recent years, the use of Full HD has continued to spread among households worldwide.
At the same time, however, proposals are being made vigorously for new television
broadcasting standards that go beyond HD, and great efforts are also being made proactively
to satisfy the growing need for next-generation, high-definition images that surpass HD in fields
such as digital cinema, presentations, monitoring/control, and medical applications.
JVC's new 1.75-inch 8K4K D-ILA device is a display device that satisfies expanding ultrahigh-
definition imaging requirements by providing the world's highest level*1 of resolution. In
addition to the contribution that the device will make to progress in next-generation ultra-highdefinition
imaging technology such as Super Hi-Vision, JVC also plans to utilize it in
development of the ultimate in imaging technology: ultra-realistic 3D display technology.

What are D-ILA Reflective Liquid Crystal Devices?
D-ILA is the name given to JVC’s proprietary high-performance reflective liquid crystal
devices for projectors. These are typical LCOS (Liquid Crystal on Silicon) devices that provide
both high brightness and high definition.
JVC successfully developed the 1.3-megapixel SXGA type device in October 1997 and
launched the D-ILA projector the same year. Since that time, the company has accumulated
many years of production experience with devices for high-end projectors and continually
released new products: in May 2004, the company launched the world’s first domestic Full HD
front-projection system and then launched rear-projection systems into the US market in the
July the same year.
The D-ILA Full High-Definition home theater projector DLA-HD1 launched in January 2007
utilized a newly developed 0.7-inch Full High-Definition D-ILA device and a new optical engine
to achieve 15,000:1 native contrast ratio and "true black" expression without using an iris
mechanism. Furthermore, the successor model DLA-HD100 introduced in December 2007
achieved the industry’s highest*4 30,000:1 native contrast ratio. Both models were well
reviewed and proved great hit products in the global market.
The professional D-ILA projector, DLA-SH4K, which went on sale in 2008, achieves both
10,000:1 high contrast ratio and about 10-megapixel resolution more than four times the Full
High-Definition level. This overwhelming image quality has received high praise, particularly in
the presentation field.

Barco und JVC arbeiten zusammen DLA-SH4K ! jvc_barco_lx5-l

ich hatte den 4K Beamer von JVC ja bereits im Otober 2007 angekündigt (siehe hier) aber die Zusammenarbeit mit Barco hat anscheinend nochmals zu 1000ASNI Lumen mehr geführt. Die Zusammenarbeit bedeutet, dass unsere D-ILA Technologie in die Lichtkanonen von Barco intergriert wird. Wenn schon denn schon, dann den größten 10MB-LCOS CHIP mit einer Auflösung von 4096x2400 . Den neuen LX-5 Projektor konnte man auf der ISE in Amsterdam sehen. Zu der 10 Megapixel Auflösung kommt noch eine extreme Farbengenauigkeit und der JVC typische Kontrast von 10,000:1 bei reichlichen 4500 ANSI Lumen Mit dem LX-5 Barcos kann man auch bis vier WUXGA (Pixel 1920x1200) Bilder gleichzeitig anzeigen, auch sind PIP (Bild im Bild-Projektionen möglich. Leider hat sich der Preis von ca 80.000,-Euro noch nicht bestätigt. www.barco.com 

Barco and JVC to announce cooperation on LCoS display technology

Barco, a global innovator and industry leader in digital visualization, is pleased to announce its cooperation with professional electronics company JVC on the implementation of JVC’s D-ILA technology.

The LX-5 is bound to become the projector of choice for ultra high-resolution applications.”

“We were very pleased to team up with Barco,” adds Keiichiro Doi, JVC’s chief technology officer, “because we knew that Barco is a historically established top performance projector manufacturer with the right know-how to leverage our 10 megapixel D-ILA technology, and the right savvy to make this high resolution concept a success. The time is now for LCoS technology to conquer the market, and thanks to the partnership with Barco, we can make it happen.”

Visitors to Integrated Systems Europe, which is Europe’s largest professional AV exhibition, will be able to see Barco’s LX-5 at Barco booth J73. ISE takes place from January 29 until January 31, 2008, in Amsterdam’s RAI exhibition halls. It will be shown connected to Barco’s award-winning XDS-1000 display management system, to demonstrate its advanced ultra-high brightness collaboration capabilities.
10 megapixel, 4,500 lumens LCoS projector
 LX-5 pushes revolutionary LCoS technology to its limits by being the world’s first projector to offer an incredible 10 million pixel resolution – more than four times HD. With a bright light output of up to 4,500 lumens and a high contrast ratio of 10,000:1, the LX-5 delivers an image detail and color quality on par with human eyesight.Ultra-high resolution for demanding applications

The LX-5’s high pixel density offers the ideal solution for presentation or collaboration environments that need the ultra-high resolution and the best image quality. It’s ideally suited for high-end boardrooms for the oil and gas industry, automotive companies, banking and insurance multinationals and other companies that need to display large quantities of information at the same time.

With Barco’s LX-5, you can display up to four WUXGA (1920x1200 pixels) images for design and CAD applications without compromising their original image quality.

Ultimate single-projector solution

The Barco LX-5 is the ideal solution for presentation or collaboration environments that need the best resolution and the best image quality, without resorting to multi-channel setups. No longer will you have to invest in multiple projectors, and staff need only operate and maintain a single piece of equipment.

Ergonomic design

You can freely adapt the color temperature of the LX-5 to match the lighting circumstances of its surroundings. Together with its 10,000:1 contrast ratio, this makes it a suitable choice for venues with different types of illumination.

d-ila_chipsUngeachtet der stürmischen Zeiten, die JVC (Japan Victor Company) gerade mit dem Verkauf an Kenwood durchmacht (siehe unsere alte Blog-News 14.06.07), geht die Entwicklung (Gott sei Dank) weiter. Ein neuer D-ILA (Direct Image Light Amplifier) hat das Licht der Welt erblickt. Dieser hat eine Auflösung von 4K2K mit genau 4096x2400Pixel. Der Kontrast ist mit 20.000:1 sehr hoch und auch die Response-Zeit mit 4.5ms ausreichend niedrig. Jetzt fehlt nur noch der bezahlbaren Beamer mit mindestens 4000 ANSI-Lumen dazu. Hier die Daten des Chips (siehe auch Beitrag zum neuen anorganischen Sony SXRD-Chip)dila_4k2k

  • Device size 1.27-inch diagonal
  • No. of pixels (H x V) 4096 x 2400 pixels
  • Pixel pitch 6.8 μm
  • Gap between pixels 0.25 μm
  • Aperture ratio 93%
  • Device contrast 20,000:1
  • Response time (tr+tf) 4.5 ms
  • LC mode Vertical Aligned LC
  • LC alignment film Light stabilized inorganic alignment film

Doch das wird noch ein Weilchen dauern, wobei wir ja schon letztes Jahr im August 2006, hier in den Technik-News berichtet hatten, dass JVC daran arbeitet und wir fest im Herbst mit einem 1920x1080 HDAV-Beamer und dann mit einem 4000 ANSI-Lumen Beamer rechnen. Der Preis steht allerdings noch in den Sternen und der Name " JVC HD 100 " ist auch nur eine Vermutung. d-ila_roudmap
