JVC create 35-megapixel 8k x 4k projector LCD

This is one of those situations where a diagram helps to describe far more than words could manage.  JVC have unveiled a 1.75-inch 8K4K D-ILA (Direct-Drive Image Light Amplifier) - in other words, the panel found in LCD projectors that creates the picture - capable of 17x full, 1080p high-definition.  That works out to a roughly 35-megapixel image, or 8,192 x 4,320 resolution.  In this diagram, the little green box in the lower left-hand corner is your beautiful new HDTV; the big blue oblong, together with the yellow section at the side, is the new JVC projection.

It's not only size, but pixel density.  JVC have managed to increase the ratio of area per pixel by 50-percent over its previous 4,096 x 2,400 LCD panel (which was developed in June 2007).  That gives the company the title of World's first real Super Hi-Vision definition device.

All very well, but what about a commercial release?  Well, the 8K4K D-ILA's predecessor, the 1.27-inch 4K2K D-ILA, made it from development to inclusion in the JVC DLA-SH4K projector (shown below) in less than nine months.  That could mean an available projector using the new, 35-megapixel panel by January 2009.

Press Release:

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 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.

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, 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”.
