At TouchTurns, we offer foundry services where we manufacture capacitive touch screen modules based on a customer's designs. This involves a third party IC controller supplier which provides the IC controller, firmware, FPC design, and sensor design. In addition, the customer provides the specification and mechanical design requirements. An added benefit to this partnership is that our final design files run in volume without modification which will decrease manufacturing time.
Our manufacturing line is compatible with numerous design architectures and touch panel LCD lamination for glass- and film-based sensor solutions. |
