Touch sensitive displays

摘要

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.
