Apple OLED Hopes Hinge on Rural Japan Manufacturer

Apple Inc.'s quest to adopt advanced displays for its next-generation iPhone hinges on a single supplier in the Japanese countryside.

Canon Tokki Corp., surrounded by rice fields in the city of Mitsuke in Niigata prefecture, has a near monopoly on the machines capable of making screens with organic light-emitting diodes, which enable sharp, vibrant displays that use less energy.
