Problems solved by technology

[0006] Including a touch panel in a display is desirable to provide a display with touch sensing capability, but may add undesired bulk to the display
Touch panel substrates can also reduce light transmission and thus interfere with the display's ability to display an image to the user

Embodiment Construction

[0047] exist figure 1 An electronic device of the type that may be provided with a display is shown in . Such as figure 1 As shown in , the electronic device 10 may have a housing 12 . Buttons, input and output ports, and other components 16 may be provided in the housing 12 . Display 14 may be mounted on the front surface of device 10 in housing 12 (eg figure 1 shown in ) or may be installed in other suitable locations within the housing 12. If desired, housing 12 may have multiple parts, such as a first part and a second part connected with a hinge (ie, housing 12 may be associated with a portable computer or other hinged device.)

[0048] Electronic device 10 may be a computer monitor for a desktop computer, a kiosk, a desk-based computer, a portable computer such as a laptop or tablet computer, a media player, a television, a gaming device, a cell phone, or other handheld computing device, or may are somewhat smaller portable devices. Examples of smaller portable ele...

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.

Description

[0001] This application claims US Patent Application No. filed July 19, 2011. 13 / 186,238, which application is hereby incorporated by reference in its entirety. Background technique [0002] This application relates to displays, and more particularly, to displays that include touch sensors. [0003] Displays are widely used in electronic devices to display images. Displays such as organic light emitting diode (OLED) displays use organic light emitting materials to generate light. [0004] In many electronic devices it is desirable to incorporate touch screen functionality into the display. Touch screens can be used to provide devices with a touch interface. A touch interface may allow a user to interact with the device through on-screen touch commands such as finger taps and swipes. [0005] A typical touch screen includes a touch sensor panel having an array of touch sensor electrodes. The touch sensor processing circuitry is capable of measuring changes in capacitance a...
