A prototype of the “world’s smallest 3-D full HD display” using thin film transistor (TFT) has been developed by Ortus Technology, a Japanese firm.

At 4.8 inches, the screen features glasses-free 3-D effects. It’s so dense at 546 pixels per inch (229 pixels per inch in 3-D mode) that the human eye can’t actually discern one pixel from another, creating a seamless, realistic image, claims Ortus.

The display uses a polarizing film called Xpol. The film enables the panel to alternately show images for the right and left eye on each line. Its viewing angle (160 degrees) and color capabilities (up to 16.77 million hues) should be particularly useful in commercial 3-D cameras, says Ortus.

Ortus says it has yet to set a market launch date, but it could start production “in the near future.”
