Blue Phase LCDs Yield Triple Panel Resolution – Better Grab a 12K Camera
Researchers have developed a new LCD technology that they claim could “triple the sharpness” of traditional LCD displays. It is called “blue-phase LCD” and it will let panel makers pack more pixels in and require less power.
If you know me, I’m obsessed with VR, and this is something that could prove to be perfect for HMD panels as that is a big bottleneck in the experience. I believe I’ve read we need around 4K per eye to get a good quality image. That and a beefy gaming PC to drive it.
On the film side of things this gives pixel peepers like me even more reason to shoot at 6K & 8K as the technology accelerates the increasing resolution of displays that will eventually make it into the home. DIT’s excitement intensifies.
“Today’s Apple Retina displays have a resolution density of about 500 pixels per inch,” said Shin-Tson Wu, who led the research team at the University of Central Florida’s College of Optics and Photonics (CREOL). “With our new technology, a resolution density of 1500 pixels per inch could be achieved on the same sized screen. This is especially attractive for virtual reality headsets or augmented reality technology, which must achieve high resolution in a small screen to look sharp when placed close to our eyes.”
Even though the science of it is complicated, the concept is simple: Standard panels of today contain subpixels that contain RGB filters that are combined to create different colored pixels. See image above.
With blue phase LCD, they can be switched ten times faster (sub millisecond). At this speed, our eyes cannot see the separate colors switching, but how they blend into one singular color. This eliminates the filter altogether resulting in saved space. What used to fit a 4K panel could be used to create a 12K panel of the same size. As I mentioned above, this tech could be a boon for VR. For reference, the Oculus is 2160 x 1200 spread over two OLED displays.
Blue phase potentially could deliver a HMD running at 6480 x 3600.
(let’s not go crazy here though, I think we’ll get some years between us before we’re doing video production at 12K)
