Mutual capacitance touch sensing device
Abstract:
A mutual capacitive touch sensing device is disclosed. The device can include nodes for sensing a touch at the device and for sensing a force applied to the device. Some nodes can perform both touch and force sensing; while other nodes can perform touch sensing. The device can include distinct individual drive lines for driving the nodes and separate distinct individual sense lines for transmitting touch or force signals from the nodes. The nodes can form groups, where the nodes in each group can be coupled to the same drive line and to different sense lines and where each node in a group can be coupled to a node in a different group by the same sense line. Each node can be set up with a different combination of drive and sense lines coupled thereto. An example device can be a click wheel.
