It's easy to forget that Samsung is a multi-tentacled company that builds much more than TVs and phones. For instance, it manufactures CPUs for arch-foe Apple and makes small-to-medium OLED panels for various companies, not just its own mobile division. According to Reuters, Samsung will invest another $3.6 billion into its OLED business to offset flagging smartphone sales. Most of that cash will go into a new production line producing curved panels for the Galaxy Note edge and third-party devices. And Samsung's not the only South Korean manufacturer dumping more money into OLEDs. LG will also stake nearly $1 billion on new OLED capacity for large-panel items like TVs, as well. The takeaway? Given the display dominance of the two companies, many more OLED devices -- both big and small -- should be hitting the market soon.
