As of now, Samsung owns three plants that produce OLED displays. At least two of them are in the vicinity of South Korean capital Seoul. 85% of the display business is owned by Samsung Electronics, while the other 15% is held by Samsung Display. In addition to the displays, Samsung makes the chipsets, memory modules, and modems for its mobile products in-house. The Galaxy S6 edge's estimated bill of materials is $290 per unit, which makes it the most expensive smartphone Samsung has produced.
