Abstract: An in-cell touchscreen panel includes columns of transmit electrodes and rows of sensing electrodes, wherein each row of sensing electrodes comprises a first subset of sensing electrodes coupled to control circuitry via a first subset of receiving traces and a second subset of sensing electrodes coupled to the control circuitry via a second subset of receiving traces. To enable multi-touch functionality, the in-cell touchscreen panel operates in a scanning mode where capacitance is measured at each node where the sensing electrodes intersect the transmit electrodes. During the scanning mode, the control circuitry senses the first and second subsets of receiving traces while applying drive signals to pairs of transmit electrodes. After a drive signal has been applied to each of the transmit electrodes, each of the nodes are measured to detect a capacitance. This capacitance is indicative of a user touch on the in-cell touchscreen panel.

Abstract: Accumulators that operate to fully or partially remove noise from a signal, including removing noise inserted into the signal by the accumulator itself. In some embodiments, an accumulator may be operated in a sampling phase and a transfer phase each time the accumulator samples an input signal. In some such embodiments, an op-amp of an accumulation circuit of the accumulator may be auto-zeroed during some or all of the sampling phases of an accumulation period. In some embodiments in which the op-amp is auto-zeroed during some or all of the sampling phases, the accumulation circuit may include a holding capacitor that, during an auto-zeroing process, holds a value output by the op-amp during a prior transfer phase. Including such a holding capacitor in an accumulator may reduce a voltage that the op-amp output rises following the auto-zero process, which may reduce a bandwidth and noise of the accumulation circuit.

Abstract: A directional capacitive proximity sensor circuit capable of providing directional capacitive proximity sensing includes one or more guard electrodes, a first sensor, and a second sensor. The directional capacitive proximity sensor is installed in a device such that the first sensor is positioned near a first component of the device, and the second sensor is positioned near a second component of the device. The first and second sensors measure a capacitance to detect proximity of a user relative to the respective sensor, wherein the detected proximity is interpreted to determine a direction in which the user proximity is detected relative to the directional capacitive proximity sensor circuit. The guard electrode is provided to mitigate stray capacitance to reduce error in the capacitance measurements obtained by the first and second sensors.

Abstract: A touch screen having a capacitive touch-sensitive pad overlaying a display area incorporates one or more slide features each having conductive plates. The conductive plates are located outside the display area of the touch screen and are powered via one or more connections to existing touch sensor circuitry comprising the touch-sensitive pad. The slide features of the touch screen do not obstruct a user's view of the display screen and, when compared to conventional touch screen slide features, reduce the circuitry required for detecting and/or processing a slide touch.

Abstract: A method tracks a plurality of touch points across successive frames of a touch sensitive input device to determine a trajectory. Each touch point on a frame of a touch sensitive input device is correlated with another distinct touch point on a subsequent frame of the same touch sensitive input device. The correlation is based on examining in the subsequent frame an area surrounding each touch point on the previous frame. Touch points identified within this search area are prioritized based on a projected trajectory through the prior touch point based on historical data.
