Abstract: An electronic device may have a touch sensitive display that is insensitive to the presence of moisture. An array of pixels in the display may be used to display images. A display cover layer may overlap the array of pixels. A light source may illuminate an external object such as a finger of a user when the object contacts a surface of the display cover layer.

Abstract: An active pen communicates with a sensor controller using a series of time slots, to receive uplink signals from and transmit downlink signals to the sensor controller. The series of time slots are determined based on the reception timing, by the active pen, of an uplink signal used as a reference time. The active pen determines whether or not the uplink signal is received and, if yes, the active pen transmits a first downlink signal using a time within the series of time slots. If no, the active pen transmits a second downlink signal using both a time within the series of time slots and a time outside the series of time slots. The second downlink signal is formed by repeating a unit signal that is shorter in duration than each of the series of time slots, to ensure reception by the sensor controller of at least one unit signal.
