LG introduces world's first OLED TVs with a 3840 x 2160 pixels (4K) resolution. These models have a curved display and will soon be sold in South Korea in 65" and 77" sizes.
The displays use LG's Four-Colour Pixel WRGB technology and are equipped with LG's multi-channel Ultra Surround Sound System. The operating system on board of these TVs is based on webOS, which LG bought from HP in 2013.
European or US pricing and availability is unknown.
