South Korea’s LG Display said on Monday that it will change its investment priority to advanced displays called OLEDs as Chinese manufacturers quickly catch up with their South Korean rivals in the LCD market. LG Display Co, a supplier to Apple Inc, said that over the next three years it plans to spend 10 trillion won ($8.4 billion) on future displays including OLED, flexible displays and high-end LCD screens. It did not give breakdown figures, saying the size for each type of display will hinge on market situations. LG Display and LG Electronics are the lone manufacturers of OLED TVs, which are still more expensive and more difficult to produce than LCD TVs. LG Display’s OLED business has been losing money. OLEDs, or organic light-emitting diodes, require no backlight and can be made into a flexible display. Rival Samsung Electronics uses OLEDs only for small-size devices such as smartphones, saying that big-size OLED TVs face challenges in prices and productions. But LG vowed to continue its high-stake bet.
