TOUCH SENSITIVE DISPLAYS

摘要

Displays such as organic light-emitting diode displays may be provided with touch sensing capabilities. A touch sensor may be formed from electrodes located on a thin-film encapsulation layer 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 may be used to provide control signals to light-emitting diodes 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 or polarizer may be used as electrodes for a touch sensor. Displays may have active regions and inactive peripheral portions. The displays may have edge portions that are bent along a bend axis that is within the active region to form a borderless display. Virtual buttons may be formed on the bent edge portions.
