Patent
Synaptics | Date: 2015-06-25

Embodiments described herein include an input device, a display device having a capacitive sensing device, a processing system and a method for detecting presence of an input object using a capacitive sensing device. In one embodiment, an input device includes a plurality of sensor electrodes arranged in a planar matrix array. Each sensor electrode is coupled to unique routing trace and has an identical geometric plan form that is symmetrical about a center of area of the sensor electrode. The geometric plan form of each sensor electrode includes core and a plurality of protrusions extending outward from the core. The protrusions are configured to overlap with protrusions extending outward from each adjacent sensor electrode of the matrix array.

The protrusions are configured to overlap with protrusions extending outward from each adjacent sensor electrode of the matrix array.


Methods, systems and devices are described for operating an electronic system which includes a first plurality of sensor electrodes disposed in a first layer and configured to detect input objects at an input surface of the input device, the first plurality of sensor electrodes including a first subset of transmitter electrodes; a second plurality of sensor electrodes configured to detect a force imparted to the input surface and configured for capacitive coupling with the first subset of transmitter electrodes; and a compressible dielectric configured to compress in response to force applied to the input surface. The capacitive coupling between the transmitter electrodes and the second plurality of sensor electrodes is configured to vary in response to the applied force.


Methods, systems and devices implement changes in operating mode for a media player, wireless telephone, portable computer or other device having a force sensor and a proximity sensor. A force indication is received from the force sensor and a proximity indication is received from the proximity sensor responsive to user input. The device is then switched from a second operating mode to a first operating mode in response to an occurrence of user input being indicated by both the force and proximity indications. A trigger event occurring during one of the operating modes evokes a response by the device that is not evoked by the trigger event in the other of the first and the second operating modes.

Embodiments of the invention generally provide an input device with display screens that periodically update (refresh) the screen by selectively driving common electrodes corresponding to pixels in a display line. In general, the input devices drive each electrode until each display line (and each pixel) of a display frame is updated. In addition to updating the display, the input device may perform capacitive sensing using the display screen as a proximity sensing area. To do this, the input device may interleave periods of capacitive sensing between periods of updating the display based on a display frame. For example, the input device may update the first half of display lines of the display screen, pause display updating, perform capacitive sensing, and finish updating the rest of the display lines. Further still, the input device may use common electrodes for both updating the display and performing capacitive sensing.
