Back in October 2010, Ortus Technology announced that it had developed a 4.8-inch color liquid crystal display with the world's smallest size screen and a pixel density of 458 pixels per inch (ppi) in 2D. This pixel density is beyond the detection limit of the human eye.
Now, the company has released the Hyper Amorphous Silicon TFT (HAST) screen, which reduces the space in between pixels and allows light to be transmitted more efficiently to create a high aperture ratio. Just like its predecessor, the 4.8-inch LCD boasts 458ppi in 2D mode, but it can also pull off an impressive 229ppi in 3D mode. DigInfo TV has a video of the 3D screen in action:
The screen's amazing specifications make it the world's smallest 3D display with full HD resolution (1920 x 1080 pixels), according to the company. Unfortunately, 3D glasses are required to view 3D images. It can display 16.77 million colors, has a viewing angle of 160 degrees, and comes with an LED backlight.
At the Embedded Systems Expo (ESEC), the company explained that the 3D effect is achieved by using a circular polarizing film called Xpol, developed by Arisawa Manufacturing. This film is affixed to the panel with extremely precise alignment and because this system shows images for the left and right eye alternately on each line, the vertical resolution must be halved.
"We expect this technology will be utilized in the monitors of commercial 3D cameras," an Ortus Technology spokesperson said in a statement. "It could be used to check 3D images immediately after taking them. We haven't set a date for the market launch, but we could start production in the near future, depending on demand from customers."
Personally, this is the type of screen I want to see in a phone one day. The 3D part doesn't impress me much, but the resolution certainly does (even if my eyes can't tell the difference!).
