Problems solved by technology
[0011] When a parasitic capacitance is generated between the bridge portion and the metal mesh electrode, the time constant increases and RC delay occurs, thereby causing a delay in transmitting the touch sensing signal
In addition, due to the parasitic capacitance between the bridge part and the metal mesh electrode, the overall capacitance of the touch electrode also increases, thereby deteriorating the touch sensitivity

Disclosed is a touch organic light emitting display device capable of stably connecting metal mesh electrodes to each other using a plurality of bridges and minimizing generation of parasitic capacitance. The display device includes: an organic light emitting array including a plurality of pixel openings and a bank insulating film disposed at regions between the pixel openings; a touch electrode array bonded to the organic light emitting array, the touch electrode array including: a plurality of first mesh electrodes , arranged along the first direction and have a multi-grid structure; a plurality of second mesh electrodes, arranged in the same layer as the first mesh electrodes, electrically insulated from the first mesh electrodes, and arranged in a direction crossing the first direction in the second direction and have a multi-grid structure; the bridge part is disposed in a layer different from the first mesh electrode and connects the first mesh electrodes arranged adjacent to each other along the first direction to each other through a contact hole; the connection patterns to connect the second mesh electrodes arranged adjacent to each other in the second direction to each other, and the bridging portion only overlaps and crosses the connection patterns.
Description
[0001] This application claims the benefit of Korean Patent Application No. 10-2016-0184382 filed on December 30, 2016, which is hereby incorporated by reference as if fully set forth herein. technical field [0002] The present invention relates to a touch organic light emitting display device, and more particularly, to a touch organic light emitting display device capable of preventing an increase of a time constant and generation of parasitic capacitance in an electrode provided at a touch sensor. Background technique [0003] An image display device that realizes various information on a screen is a core technology of the information and communication age, and is developing toward being thinner, lighter, more portable, and having higher performance. As a flat panel display device capable of overcoming disadvantageous weight and volume problems of a cathode ray tube (CRT), for example, an organic light emitting display device that displays an image by controlling luminous ...
