Abstract: An input device comprises a first and second pluralities of capacitive sensor electrodes. The first plurality of capacitive sensor electrodes is oriented along a first axis, disposed in a first layer, and configured to update a display screen of the input device. The second plurality of capacitive sensor electrodes is oriented along a second axis that differs from the first axis. A display region of the display screen has a first dimension along the first axis and a second dimension the second axis. At least one sensor electrode of the first plurality of capacitive sensor electrodes extends fully across the first dimension of the display region. Individual sensor electrodes of the second plurality of capacitive sensor electrodes do not extend fully across the second dimension of the display region.

Abstract: In a method of operating a touch screen, an object interaction is detected with the touch screen while in a first doze mode. It is determined if a detected object interaction with the touch screen is a valid input object interaction with the touch screen. In response to determining the object interaction is a valid input object interaction, the touch screen is transitioned from the first doze mode to a gesture recognition mode. The touch screen is transitioned from the gesture recognition mode to an active mode in response to a determination of a valid gesture interaction with the touch screen by the input object.

Abstract: A system and method for input sensing comprises a display device having at least one piezoresistive sensing transistor. During a first period, a first resulting signal is received with a first data line by driving a first piezoresistive sensing transistor of a first subpixel of the display device with a first select signal. The first resulting signal corresponds to a change in resistance of the first piezoresistive sensing transistor. Further, at least one of force information and positional information associated with an input object may be determined at least partially based on the change in resistance.

Abstract: A capacitive sensing device has a first plurality of sensor electrodes, and a second plurality of sensor electrodes overlapping the first plurality of sensor electrodes. A first sensor electrode of the second plurality of electrodes overlaps a first subset of the first plurality of electrodes and comprises apertures disposed according to first codes. The first codes comprise first and second coefficients and along one of the first plurality of sensor electrodes. Each aperture may correspond to one of the first coefficients. The capacitive sensing device further comprises a processing system coupled to the first and second plurality of sensor electrodes. The processing system may be configured to receive resulting signals with the second plurality of sensor electrodes to determine positional information for an input object within a sensing region of the capacitive sensing device.

Abstract: This disclosure generally provides an input device with a matrix sensor that includes a plurality of sensor electrodes arranged on a common surface or plane. Moreover, the input device includes routing traces that electrically couple the sensor electrodes to analog front ends (AFEs). Because of the spatial relationships between these electrical components, the sensor electrodes can be categorized into groups where each of the sensors in the group is affected by a common noise source. The capacitive measurements for the sensor electrodes in each of the groups are compared to a touch threshold to determine if an input object (e.g., finger or stylus) is proximate to the sensor electrodes. If the capacitive measurements are below the touch threshold, the input device calculates an offset value that compensates for the noise. After the offset is applied, the compensated capacitive measurements are used to generate a capacitive image.

Abstract: A display device can use clock dithering to spread the frequency spectrum of the clock signal (and the signals derived therefrom) to mitigate interference with other components or systems in a host device. However, dithering the clock signal can introduce display artifacts into the display device. For example, lines or rows in the display may flicker, the brightness of display lines may be non-uniform, or color shifts in displayed pixels. To reduce display artifacts, the embodiments herein synchronize clock dithering to a display update event. That is, the display device varies a parameter of clock dithering so that the dithering is synchronized to the display update event. In another embodiment, the clock dithering is set according to the rate at which display lines or sub-pixels are updated. In another embodiment, clock dithering is synchronized to a display frame update period.
