Officials from LG say that the huge investment in OLEDs will help LG gain a competitive advantage over Samsung in a "number of markets". Obviously OLED TV is one of those markets, but I'm not sure which other markets is LG hinting at. Perhaps the mobile display market, which LG aims to tackle with flexible plastic-based OLEDs.
LG Display will be expanding its LCD production capacity due to soaring demand from mobile displays (mostly from Apple), and will also spend more on OLEDs, Oxide-TFT technology and flexible displays.
Last week LG started to accept pre-orders for its 55" OLED TV, the 55EM9700, beating Samsung to being the first commercial OLED TV producer. The focus on OLED technology is not really news. Back in September 2012 LG's Chairman said that LG will devote its main resources to develop OLED TVs and displays - which he considers to be one of its future growth engines.
