A method for initiating fingerprint capture in an electronic device is described. The device includes a touch screen with a sensing region, a touch controller, a fingerprint controller, and a host. The device is placed in a low power doze mode where the fingerprint controller is in a low power state and the device scans for an object proximate to the sensing region. When an object is proximate to the sensing region, the device executes a validation mode to determine whether the object is a fingerprint. When a fingerprint is detected, the device sends a wake up signal to the fingerprint controller and places the fingerprint controller in a high power mode. One or more fingerprint images are then captured.

A method. The method may include obtaining force information regarding an input force applied by an input object to a sensing region of an input device. The method may include determining, using the force information, that the input force exceeds a first force threshold. The method may include determining, using the force information, whether the input force exceeds a second force threshold. The method may include obtaining positional information for an input object in the sensing region of the input device. The method may include determining, using the positional information, that a change in position of the input object is less than a distance threshold when the input force exceeds the second force threshold. The method may include performing an interface action within a graphical user interface in response to determining that the input force decreases below at least the second force threshold.

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.
