JVC 8192×4320 Projectors
The Japanese got tired of the 1080p resolution and they decided it was time to raise the standard once again for the masses. Maybe you’ve heard about the upcoming Super-Hi Vision technology developed by NHK Japan. This technology enables TV broadcasting resolutions of nearly 33 megapixels. That translates into 7680 x 4320 pixels resolutions, with 60 frame/second sequential scanning plus 22.2 multichannel sound. Quite impressive, but I wonder what they will use for the actual infrastructure, as wireless systems can’t yet deliver Gb/s speeds properly. Anyhow, JVC took NHK’s idea and implemented into small chips in order to bring Super Hi-Vision quality to projectors.
The new D-ILA (Direct-Drive Image Light Amplifier) chips from JVC are specifically built for projectors. Improved 8K4K D-ILA chips now measure only 1.75-inch and provide world's largest number of pixels, being able to display images of approximately 35 megapixels or 8192 x 4320 resolutions. That is the equivalent of more than 17 times the level of Full High-Definition coming from current 1080p screens.
The 8K4K chips have approximately 50% higher density in their ratio of area per pixel as compared to the previous 1.27-inch 4K2K device. JVC also claims that the future projectors will provide "high-quality images without a distracting pixel structure", plus they will sport "high light availability" and "higher contrast ratios".
Here are some more details on the 84K4 chips:
1. 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.
2. By applying the same inorganic alignment layer used on previous D-ILA devices, the tradition of long life and high durability is successfully maintained.
3. 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.
4. 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.
What JVC is implying with the release of their new 84K4 chips is that display makers won’t dare build large enough Super Hi-Vision displays for the masses. Imagine buying and installing a 110” screen into your small home. All JVC is suggesting is that projectors will get more popular in the future, especially if people want larger resolutions.
