Stunning pure colors in NanoCell TV's Real 4K. At approximately 8 million pixels, a 4K TV delivers an image that is noticeably sharper and more detailed than your standard HD TV. In NanoCell TV, the 4K resolution is complemented by NanoCell technology for a 4K experience that exceeds international standards. LG NanoCell TV uses nanoparticles. This is our proprietary Nanotechnology to filter and refine images and color by removing impurities from RGB color mixing. This means that only pure, accurate colors are displayed on the screen. The result is a more vivid, more realistic image. LG NanoCell TV is not afraid of a dark room. With Full Array Dimming, NanoCell accurately controls individual LED backlight units. This results in deeper blacks and minimal backlight bleeding for greater contrast and a more detailed image.
