At the FPD International show currently being held in Japan, Samsung's display division demonstrated its 63-inch plasma display panel with a resolution of 4096x2160 pixels, more commonly referred to as 4K in the industry. The company was able to accomplish this feat by shrinking the size of each pixel, now at 0.339mmx0.363mm (0.13x0.14 inches), by slimming down the barrier rib structure and revising the transparent electrode and bus electrode. These pixels are less than half the size of a typical pixel found in a modern 63-inch, 1920x1080 HDTV.
Little other specifics are known about the Samsung display, including the panel thickness, but it is the largest display with a superfine pixel pitch among other prototypes using similar technology, including those from Pioneer, Sharp and Japan Broadcasting Corp (NHK), which have built 20-inch or smaller displays.
Many believe 4K is the future of HD, as it offers about four times the definition of a modern 1080p HDTV set, also equivalent to about 9 megapixels. [viaTech-On]
