World’s highest*
1 35 megapixel pixel count:
More than 17 times Full High-Definition
[FONT=Arial,Bold][FONT=Arial,Bold]JVC Develops 1.75-inch 8K4K D-ILA Device[/FONT][/FONT]
~ 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”.
