摘要： In a method of interference avoidance for a capacitive sensor device, a transmitter signal is transmitted with a transmitter electrode of the capacitive sensor device. A resulting signal is received with a receiver electrode of the capacitive sensor device. The resulting signal corresponds to the transmitter signal. A first demodulated output is acquired by demodulating the resulting signal in a first way. A second demodulated output is acquired by demodulating the resulting signal in a second way, where the second way and the first way differ. A shift is made from using the first demodulated output for determining positional information to using the second demodulated output for determining positional information. The shift is based at least in part upon an amount of interference.

摘要： A processing system for a capacitive touch screen comprises sensor circuitry and control logic. The sensor circuitry is configured to be communicatively coupled with sensor electrodes of the capacitive touch screen. The control logic is configured to operate the capacitive touch screen in a first mode comprising interference sensing at a first level and input object sensing. The control logic is also configured to operate the capacitive touch screen in a second mode instead of in the first mode in response to: interference measured in the first mode meeting an interference condition; and a determination that input is in a sensing region of the capacitive touch screen. While operating in the first mode, interference sensing is performed during a non-display update time. While operating in the second mode, interference sensing with the capacitive touch screen is either not performed or else is performed at a second level that is lower in fidelity than the first level.

摘要： The various embodiments described herein provide input devices configured to selectively operate in two different sensing regimes. The first sensing regime is configured to determine positional information for ungloved fingers in the sensing region. The second sensing regime is configured to determine positional information for gloved fingers in the sensing region. The input devices are further configured to switch from operating in the first sensing regime to the second sensing regime responsive to detecting an input gesture that meets each of a set of criteria, where the set of criteria includes a measure of sensor value stability corresponding to the input gesture being beyond a sensor value stability threshold level. So implemented, the input device allows a user to easily switch between two different sensing regimes, and thus can facilitate the use of the device with both gloved and ungloved fingers providing input.

摘要： 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.

摘要： Devices and methods are provided that utilize a first electrode disposed on a first substrate and a second electrode disposed on a second substrate, where the first electrode and the second electrode define at least part of a variable capacitance. A third substrate is arranged between the first substrate and the second substrate, the third substrate having an opening arranged such that at least a portion of the first electrode and the second electrode overlap the opening. A transmission element is provided that partially overlaps the opening. The transmission element is physically coupled to the second electrode such that a force biasing the transmission element causes the second electrode to deflect relative to the first electrode, thus changing the variable capacitance. A measurement of the variable capacitance may then be used to determine force information

摘要： In an example, a processing system for a capacitive sensing device includes a sensor module and a determination module. The sensor module comprises a receiver, coupled to a sensor electrode, configured to receive a capacitive sensing signal. The receiver includes an in-phase channel and a quadrature channel. The in-phase channel is configured to mix the capacitive sensing signal with a local oscillator signal substantially in phase with the capacitive sensing signal. The quadrature channel is configured to mix the capacitive sensing signal with a phase-shifted signal near ninety degrees out of phase with the capacitive sensing signal. The determination module is configured to measure a change in capacitance in response to a demodulated signal of the in-phase channel concurrently with measuring a non-coherent signal in response to a demodulated signal of the quadrature channel.

摘要： The embodiments described herein thus provide devices and methods that facilitate improved input devices. Specifically, the devices, systems and methods provide the ability to accurately determine user input using multiple different sensing regimes. The different sensing regimes can be used to facilitate accurate position determination of objects both at the surface and away from the surface. For example, the different sensing regimes can be used to determine position information for both ungloved and gloved fingers. In one embodiment the first sensing regime uses a first duty cycle of absolute capacitive sensing and a first duty cycle of transcapacitive sensing. The second sensing regime uses a second duty cycle of absolute capacitive sensing and a second duty cycle of transcapacitive sensing, where the second duty cycle of absolute capacitive sensing is greater than the first duty cycle of absolute capacitive sensing.
