Abstract

The invention relates to a touch sensor integrated with OLED and an OLED display device comprising the same, in particular to the touch sensor integrated with OLED and the OLED display device comprising the same which demonstrate excellent bending features, optical characteristics and electric characteristics. The touch sensor integrated with OLED includes an organic light emitting diode (OLED) device, a touch electrode having a mesh type and a self-capacitance type structure. The touch electrode is attached to a surface of the OLED device and included at least a double-layered structure thatincludes a metal layer and a metal oxide.

Description

technical field [0001] The invention relates to an OLED integrated touch sensor and an OLED image display device including the touch sensor. Background technique [0002] At present, with the development of the information society, the requirements for the display field are also increasing in various forms. Correspondingly, many flat panel display devices (Flat Panel Display device), such as Liquid Crystal Display device, Plasma Display Panel device, Electro Luminescent Display device, Organic Light-Emitting Diode Display device ) and so on. [0003] Among them, an organic light emitting diode (OLED) display device has recently attracted attention as a next-generation display device due to its advantages of fast response, high image quality, wide viewing angle, and low power consumption. [0004] On the one hand, a touch panel is favored as an input device attached to the display device and capable of inputting a user's command using a human hand or an instruction content ...
