摘要： A touch sensor panel configured to detect objects touching the panel as well as objects that are at a varying proximity to the touch sensor panel. The touch sensor panel includes circuitry that can configure the panel in a mutual capacitance (near field) architecture or a self-capacitance (far field and super far field) architecture. The touch sensor panel can also include circuitry that works to minimize an effect that a parasitic capacitance can have on the ability of the touch sensor panel to reliably detect touch and proximity events.

摘要： A system for data communication between a plurality of touch devices is disclosed. The system can include a first touch device having a first touch surface, and at least one other touch device having at least one other touch surface. The first touch device and the at least one other touch device can include a touch controller detecting communications coupling between the first touch surface and the least one other touch surface. The first touch device and the at least one other touch device can include a communication unit communicating data between the first touch device and the at least one other touch device, via the first touch surface and the at least one other touch surface, when the communications coupling is detected. The communications coupling can be detected when a coupling conduit contacts, or is proximate to, the first touch surface and at least one other touch surface.

摘要： A display having data lines that can be configured between a display mode and a touch mode is disclosed. The display can have sense regions for sensing a touch or near touch on the display during the touch mode. These same regions can display graphics or data on the display during the display mode. During display mode, the data lines in the sense regions can be configured to couple to display circuitry in order to receive data signals from the circuitry for displaying. During touch mode, the data lines in the sense regions can be configured to couple to corresponding sense lines in the regions, which in turn can couple to touch circuitry, in order to transmit touch signals to the circuitry for sensing a touch or near touch. Alternatively, during touch mode, the data lines in the sense regions can be configured to couple to ground in order to transmit residual data signals to ground for discarding.

摘要： 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.

摘要： A gate driver circuit for switching gate line voltage supplies between display and touch modes is disclosed. The circuit can include one or more switches configured to switch one or more gate lines of an integrated touch sensitive display between a display mode and a touch mode. During touch mode, the circuit can be configured to switch the gate lines to connect to a more stable voltage supply. The circuit can also be configured to reduce or eliminate interference from the display circuitry to the touch circuitry that could affect touch sensing. During display mode, the circuit can be configured to switch the gate lines to connect to a fluctuating voltage supply.
