INTEGRATED CONTACT SWITCH AND TOUCH SENSOR ELEMENTS |
摘要 |
An input device providing integrated contact switch and touch sensor elements is disclosed. A contact switch and touch sensor can be integrated so that they share a common sensor line, achieving space, cost and manufacturing savings over input devices that utilize distinct sensor lines for each of its sensor elements. By configuring a contact switch and touch sensor to share a common sensor line, a controller can use a single pin to scan both the contact switch and touch sensor elements, rather than using distinct pins to scan distinct sensor lines associated with each sensor element. By using fewer pins to scan the same number of sensor elements, a smaller controller can be used which can reduce the size and cost of the input device, and increase manufacturing throughput time associated with the input device. |
