Abstract: The use of multiple stimulation frequencies and phases to generate an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have multiple mixers. Each mixer in the sense channel can utilize a circuit capable generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the multiple mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the selected frequencies. After all steps have been completed, the demodulated signals from the multiple mixers can be used in calculations to determine an image of touch for the touch sensor panel at each frequency.

Abstract: A low power can for device wake up and unlock is disclosed. The low power scan can include one or more algorithms used to detect a sequence and/or one or more gestures to wake up a processor and unlock the device for user interaction. A sequence and/or one or more gestures can be determined by a microcontroller and/or by a separate hardware component. The microcontroller can send a notification or a wake signal to the processor and/or switch the device from an idle to an active state. By detecting a sequence and one or more gestures in the microcontroller before powering on or waking up the processor, the amount of power consumed can be reduced and the battery life extended.

Abstract: Negative pixel compensation in a touch sensor panel is disclosed. The panel can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the panel. To do so, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and compute a composite image from the captured image and the reconstructed image to replace the captured image. In addition or alternatively, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and replace the captured image with the reconstructed image.

Abstract: A touch sensitive device that detects the occurrence of an electrostatic discharge event on the device by analyzing an acquired touch image for characteristics associated with the occurrence of an ESD event is provided. An acquired touch image is analyzed for characteristics that differentiate it from a touch image generated by a user input and are correlated with an expected touch image generated by an ESD event.

Abstract: A low power can for device wake up and unlock is disclosed. The low power scan can include one or more algorithms used to detect a sequence and/or one or more gestures to wake up a processor and unlock the device. A sequence and/or one or more gestures can be determined by a microcontroller and/or by a separate hardware component. The microcontroller can send a notification to the processor and/or switch the device from an idle to an active state. By detecting the sequence and gestures in the microcontroller before waking up the processor, the battery life can be extended. In some examples, the microcontroller can determine if the sequence and gestures are due to water splashes, water film, and/or noise. In such examples, the microcontroller can reject the touch without waking up the processor, and further extending the battery life of the device.
