    摘要： Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal. The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.

    摘要： The use of one or more proximity sensors in combination with one or more touch sensors in a multi-touch panel to detect the presence of a finger, body part or other object and control or trigger one or more functions in accordance with an “image” of touch provided by the sensor outputs is disclosed. In some embodiments, one or more infrared (IR) proximity sensors can be driven with a specific stimulation frequency and emit IR light from one or more areas, which can in some embodiments correspond to one or more multi-touch sensor “pixel” locations. The reflected IR signal, if any, can be demodulated using synchronous demodulation. In some embodiments, both physical interfaces (touch and proximity sensors) can be connected to analog channels in the same electrical core.

    摘要： Touch sensor configurations for reducing electrostatic discharge events in the border area of a touch sensor panel is disclosed. Touch sensors (e.g., electrodes formed on the cover material and/or the opaque mask) can be susceptible to certain events such as arcing and discharge/joule heating, which may negatively affect touch sensor performance. Examples of the disclosure can include increasing the trace width, spacing, and/or thickness in the border area relative to the trace width, spacing, and/or thickness in the visible/active area along one or more sides of the touch sensor panel. In some examples, touch electrodes can be located exclusively in the visible/active areas along one or more sides of the touch sensor panel, while dummy sections can be included in both the border and visible/active areas. Additionally or alternatively, one or more gaps between adjacent touch electrodes in the border area or serpentine routing can be included.

    摘要： Measuring an effect of body capacitance in a touch sensitive device is disclosed. This effect can be caused by poor grounding of a user or other objects touching the device or of the device itself. The device can operate in a stray capacitance mode to measure a body capacitance effect and in a normal mode to detect a touch on the device. During the stray capacitance mode, the device can obtain a body capacitance measurement from the device. During the normal mode, the device can obtain a touch measurement from the device. The device can calculate a body capacitance factor based on a ratio between the body capacitance measurement and the touch measurement and use the body capacitance factor to compensate for erroneous or distorted touch output values from the device. Various components of the device can be switchably configured according to the particular mode.

    摘要： A space-efficient substantially transparent mutual capacitance touch sensor panel can be created by forming columns made of a substantially transparent conductive material on one side of a first substantially transparent substrate, forming rows made of the substantially transparent conductive material on one side of a second substantially transparent substrate and bringing column connections down to the second substrate. The columns can be routed off-panel at an edge of the second substrate. In some examples, the first and second transparent substrates formed from polyethylene terephthalate (PET). In some examples, the substantially transparent conductive material formed from Indium Tin Oxide (ITO).

    摘要： A method for receiving data from an input device to a computing device through a touch interface. The method includes detecting an input device, synchronizing with the input device by receiving a position signal and activating an input device scan of the touch interface, receiving a data signal from the input device through at least one of a sense line or a drive line of the touch interface, and scanning the touch interface for a touch input by applying a stimulation signal to the at least one drive line and analyzing the at least one sense line.
