Embodiment Construction

[0043] Display devices providing touch input have been widely used in the field of portable electronic devices today. By measuring changes in physical characteristics of a touch sensor close to the screen, touch input is converted into touch information, such as whether an object is approaching or touching the screen and the location of the touch input. When a user approaches or touches the screen with a finger or a stylus, the touch sensor measures changes in pressure applied to the screen, stored charge, received light, and the like. The display device may receive different image signals based on the touch information and display an image based on the received image signal.

[0044] Touch input can be achieved by using a touch sensor. Touch sensors can be classified based on measured physical properties, such as resistance, capacitance, or electromagnetic (EM) radiation.

[0045] For example, a resistive touch sensor includes two electrodes that face each other and are spa...

Abstract

A flexible display device including a touch sensor is disclosed. In one aspect, the display device includes a flexible substrate, a light emission layer formed over the flexible substrate, and an encapsulation layer formed over the light emission layer and comprising a plurality of encapsulating thin films and a touch detecting layer configured to detect a touch input. The encapsulating thin films include at least one inorganic film and at least one organic film and the touch detecting layer is interposed between a selected one of the at least one inorganic film and a selected one of the at least one organic film that are adjacent to each other.

Description

technical field [0001] The technology described generally relates to flexible display devices that include touch sensors. Background technique [0002] Display devices such as liquid crystal displays (LCD), organic light emitting diode (OLED) displays, and electrophoretic displays (EPD) include field generating electrodes and electro-optical active layers. For example, OLED displays include an organic light-emitting layer as an electro-optical active layer. The field generating electrodes are connected to switching elements such as thin film transistors (TFTs) to receive data signals. The electro-optical active layer displays images by converting data signals into optical signals. [0003] When a heavy and fragile glass substrate is used in a display panel of a display device, there are limitations on its portability and screen size. In recent years, flexible display devices using light plastic substrates as substrates of display panels have been developed because these s...
