Samsung Group, which includes Samsung Electronics Co, said on Tuesday it is raising its 2012 investment to a record $41.4 billion (26.9 billion pounds), underscoring the widening gulf between the dominant South Korean conglomerate and its faltering competitors. Best known for making massive investments in new technologies ahead of rivals, Samsung is now banking on logic chips and OLED displays to repeat its roaring success in flash chips, computer memory chips and LCD flat-screens, even as a gloomy global economic and IT spending outlook forces its peers to be conservative in spending. Samsung Group, South Korea's biggest business group, did not provide a breakdown of the 47.8 trillion won investment. But analysts have widely expected it to raise investment in mobile chips and next-generation OLED (organic light emitting diode) flat-screen displays.
