New Glasses Free 3D Display Does Not Compromise Resolution
Posted on: 05/18/2012 10:03 PM

NLT Technologies has prototyped a new naked-eye low-temperature polycrystalline silicon TFT LCD display that has six viewpoints and does not compromise 2D resolution.

Traditional LCD displays have three (red, green and blue) sub-pixels arranged in a stripe pattern, which make up one pixel. So, to display a 3D image on a 'normal' LCD display, a manufacture must use at least two pixels for displaying one pixel of the 3D image; thus reducing resolution by half or more. This sucks!

The screen size of NLT's new display is 3.1 inches, and has 427 x 240 pixels. While using the HDDP (horizontally double-density pixel) pixel alignment technology which NLD Technologies developed, NLT Technologies also applied the HxDP (horizontally x times-density pixels) technology. This is a new technology that realizes multiple viewpoints. By combining these two innovations, NLT made a very, very important product.

With HDDP, two horizontally-arranged sets of RGB sub-pixels constitute one pixel. The density of horizontally-arranged pixels is twice as high as that of vertically-arranged pixels. As a result, it becomes possible to display a 3D image having the same resolution as that of a 2D image.
While HDDP displays a 3D image with two viewpoints, the HxDP displays a 3D image with two or more viewpoints. This is caused by using as many sub-pixel sets as the number of viewpoints for each pixel. In other words, the density of sub-pixels triples for three viewpoints and increases six times for six viewpoints. I know this is a lot of information, but just keep reading!

My favorite part? The HxDP can not only display a 3D image having the same resolution as that of a 2D image, but can also display 2D and 3D images at the same time on the same screen. On top of that, it is possible to choose the number of viewpoints for a 3D image and display a 3D image with the given number of viewpoints anywhere on the screen (the viewable angle of the screen widens as the number of viewpoints increases).

NLT Technologies used kinematic parallax so images being viewed are different depending on the angle from which a 3D image is viewed. As a result, the stereoscopic effect of 3D images was increased, the company said.

NLT Technologies will exhibit the prototyped display at SID Display Week 2012, which will take place from June 5 to 7, 2012, in Boston, Massachusetts. The company aims to commercialize it by 2013. Interestingly, The company expects that the display will be employed for high-end industrial instruments. And you all thought it was for a phone
