NLT shows 3.1-inch HxDP prototype for advanced, glasses-free 3D
NEC LCD Technologies (NLT) has demonstrated a new prototype display that has six viewpoints and creates a 3D image to the naked eye. It uses low-temperature polycrystalline silicon and new HxDP (Horizontally times Density Pixels) technology to retain full resolution, however, unlike LCD displays that achieve a glasses-free 3D effect, Tech-On reported. It has six viewpoints and is just 3.1 inches in size, sporting a 427x240 resolution.
Based on the current Horizontally Double-Density Pixels (HDDP) technology, the display uses two horizontally-arranged sets of RGB sub-pixels to make one pixel, allowing for a density that is twice that of vertically-arranged pixels. This allows a 3D image with the same resolution as a 2D image. The density of sub-pixels triples for three viewpoints and increases six times for six viewpoints.
The prototype can also display 2D and 3D images simultaneously on the same screen. The viewing angle also grows as the number of viewpoints increases from two.
A kinematic parallax was used, bumping up the stereoscopic effect of 3D images.
The display will be shown off at SID Display Week scheduled for June 5-7 in Boston, Massachusetts. NLT aims to have the display tech go into production late in 2013 or later in high-end industrial instruments, though it needs to find a buyer first.
