A:Answer Hi Cecile. As the name implies, the Nano Cell Technology on the LG Nano 8 Series 4K 55 inch Class Smart UHD NanoCell TV w/ AI ThinQ® (54.6'' Diag), Model # 55SM8600PUA uses nanoparticles that absorb unwanted light wavelengths and enhances the purity of the red and green colors displayed on the screen. The result is dramatic, enhanced picture quality to give you an incredible cinematic experience. The other benefit for the use of Nona Cell Technology in an LG IPS panel is that it enables this broad spectrum of color to be seen at much wider viewing angles (even as far as 60-degrees), so you don't have to battle it out for the best seat in the house...^IFV
