Samsung is both a creator of consumer electronics (TVs, dishwashers, smartphones, notebooks, etc) and a supplier to other consumer electronics companies. They're massive. Hence my bringing up their notebooks, as I was initially confused that they'd be introducing this in their own lineup.
When you have unique access to technology, one strategic opportunity is to use that to move up the value chain from being a supplier to being a retail brand and create a differentiated product, winning market share. Samsung right now pretty much has a lock on non-TV OLED production, but is choosing not to go the path of using those in their own computer brand, and instead are selling to other computer makers. It's an option they have but have chosen not to pursue... so thats interesting.
Samsung is a big supplier of electronic parts.
