LG Electronics says that they sold 200 OLED TVs in Korea. Two months ago, when they started shipping the TVs, they reported 100 pre-orders. So this means they are currently selling about 50 sets a month. This is in Korea only, LG have yet to bring their OLED TV to other markets (it will arrive in the UK in July, and the US probably in H2 2013).
But LG is optimistic, and they expect to sell "substantial numbers of OLED and 4K TVs over the next 24 months. They hope that OLED TVs will cost about the same as high-end LED LCDs in two or three years. LG also reported that they continue to develop curved OLED TVs that will bring a "cinema-like feel to the home".
LG's 55" 55EM9700 is a Full-HD OLED TV that features 100,000,000:1 contrast ratio and fast response time (1,000 times faster than LCD according to LG). The panel is only 4mm thick and weighs only 3.5Kg. The OLED panel is based on LG Display's Oxide-TFT white-OLED with color filters (WRGB) OLED panel.
