Touchscreen chipmaker Synaptics Inc Chief Executive Rick Bergman said he would be ‘thrilled’ to win back Apple Inc as a customer after agreeing to buy the sole supplier of display driver chips for the iPhone. Synaptics, which last supplied parts to Apple around eight years ago, said on Tuesday that it would pay $475 million for the remaining outstanding shares in Renesas SP Drivers Inc, a unit of Japanese chipmaker Renesas Electronics Corp. “If Apple is to become a customer of Synaptics again we’re absolutely thrilled and happy and hope we can continue the strong relationship that it appears to have had with RSP,” Bergman told media at a news conference in Tokyo on Wednesday.
