Embodiment Construction

[0015] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

[0016] Various embodiments provide a capacitive sensing device configured for capacitive sensing of an input object comprising traces for coupling to sensor electrodes disposed at least partially within a protruding area of ​​the sensor device. In one example, the input device includes a plurality of sensor electrodes disposed within the region of the sensor electrodes. A protruding area within but not extending to the center of the sensor electrode area contains traces coupled to the sensor electrode. The highlighted area does not contain the display of the electronic system. Accordingly, the highlighted area may contain opaqu...

Abstract

An input device for capacitive sensing. The input device includes a plurality of sensor electrodes for capacitive sensing disposed in a first layer and within a sensor electrode region comprising an areal extent of the plurality of sensor electrodes. The input device also includes a plurality of routings disposed in a second layer and within a border region of the sensor electrode region, the plurality of routings layered with a first set of two or more of the plurality of sensor electrodes in the border region and electrically coupled to a second set of two or more of the plurality of sensor electrodes, wherein the second set of two or more of the plurality of sensor electrodes includes zero, one, or two of the sensor electrodes included in the first set of two or more of the plurality of sensor electrodes.

Description

technical field [0001] Embodiments relate generally to input sensing and, in particular, to improved wiring for touch sensor electrodes. Background technique [0002] Input devices including proximity sensor devices (also commonly referred to as touchpads or touch sensor devices) are widely used in a wide variety of electronic systems. A proximity sensor device typically includes a sensing area, often bounded by a surface, in which the proximity sensor device determines the presence, location and / or movement of one or more input objects. Proximity sensor devices may be used to provide an interface to electronic systems. For example, proximity sensor devices are often used as input devices in larger computing systems (such as opaque touchpads integrated in or external to notebook or desktop computers). Proximity sensor devices are also often used in smaller computing systems such as touch screens integrated in cellular telephones. [0003] Proximity sensor devices typicall...
