    Abstract: Displays such as organic light-emitting diode displays may be provided with touch sensing capabilities. A touch sensor (14) may be formed from electrodes (44) located on a thin-film encapsulation layer (84) or one or more sides of a polarizer. A single-sided or double-sided touch sensor panel may be attached to the upper or lower surface of a polarizer. Control circuitry (36) may be used to provide control signals to light-emitting diodes (50) in the display using a grid of control lines. The control lines and transparent electrode structures such as indium tin oxide structures formed on a thin-film encapsulation layer (84) or polarizer may be used as electrodes for a touch sensor. Displays (14) may have active regions (A) and inactive peripheral portions (IR). The displays (14) may have edge portions that are bent along a bend axis (122) that is within the active region (A) to form a borderless display. Virtual buttons (VB) may be formed on the bent edge portions.

    Abstract: A capacitive fingerprint sensor that may be formed of an array of sensing elements. Each capacitive sensing element of the array may register a voltage that varies with the capacitance of a capacitive coupling. A finger may capacitively couple to the individual capacitive sensing elements of the sensor, such that the sensor may sense a capacitance between each capacitive sensing element and the flesh of the fingerprint. The capacitance signal may be detected by sensing the change in voltage on the capacitive sensing element as the relative voltage between the finger and the sensing chip is changed. Alternately, the capacitance signal may be detected by sensing the change in charge received by the capacitive sensing elements as the relative voltage between the finger and the sensing chip is changed.
