Techniques for implementing and/or operating an electronic device including a display pixel layer, which writes a display image during an active period and continues displaying the display image during a blanking period, and a touch sense layer, which generates a first touch image during the active period and a second touch image during the blanking period. The electronic device further includes a controller that determines a first noise metric indicative of display-to-touch noise resulting during the active period based on the first touch image, determines a second noise metric indicative of display-to-touch noise resulting during the blanking period based on the second touch image, and instructs the touch sense layer to not generate a third touch image during a subsequent active period in response to the first noise metric being greater than a noise threshold and the second noise metric not being greater than the noise threshold.

Electronic display adaptive touch interference scheme systems and methods

Systems and methods reduce likelihood of hysteresis that reduces perceived image quality of a subsequent image frame by toggling the display pixels to relax the display pixels by overwriting previous image frame data. During non-emission periods of the pixels, the pixels may be pre-toggled or exercised to improve response time and accuracy of the pixel. Data for pixels being programmed may also be used to pre-toggle other pixels reducing overhead but increasing cross-talk. Since the amount of cross-talk is related to content of the pixels being pre-toggled, a line buffer may be used to store image data for the pixels being pre-toggled. This stored image data may be used to determine how much pre-compensation is to be applied to data for the pixels being programmed. In other words, an amount of compensation applied is based at least in part on the content (e.g., greyscale levels) of the image data.

Pre-compensation for pre-toggling-induced artifacts in electronic displays

An apparatus includes a first squelch circuit and a second squelch circuit. The first squelch circuit is configured to detect possible squelch signals in a communication signal. The second squelch circuit is configured to selectively detect the possible squelch signals in the same communication signal. The second squelch circuit is further configured to operate in a low-power state responsive to the first squelch circuit detecting none of the possible squelch signals in the communication signal. The second squelch circuit is further configured to operate in a high-power state responsive to the first squelch circuit detecting one of the possible squelch signals in the communication signal.
