Embodiment Construction

[0025] Reference will now be made in detail to the exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0026] figure 1 is a perspective view showing an organic light emitting display device with a touch sensor according to the present invention.

[0027] figure 1 The illustrated organic light emitting display device with a touch sensor includes: a plurality of sub-pixels arranged in a matrix on the substrate 111, a packaging unit 140 disposed on the sub-pixels, and a mutual capacitance disposed on the packaging unit 140 Cm.

[0028] The organic light emitting display device with a touch sensor such as figure 2 Shown are: an active area AA disposed on the substrate 111 , and a non-active area NA disposed adjacent to the active area AA. The substrate 111 is formed of a flexible material such as plastic ...

Abstract

An organic light-emitting display device having a touch sensor is discussed. The organic light-emitting display device includes a touch sensor formed in a single-layer structure and disposed on an encapsulation unit disposed on a light-emitting element. First and second bridges and first and second touch electrodes included in the touch sensor having a single-layer structure are formed of the samematerial as each other in the same plane, e.g., on the uppermost layer of the encapsulation unit, thereby simplifying the structure thereof and reducing costs.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2018-0044949 filed on April 18, 2018, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to a display device, and more particularly, to an organic light-emitting display device with a touch sensor capable of achieving structural simplification and cost reduction. Background technique [0004] A touch screen is an input device through which a user can input a command by selecting an instruction displayed on a screen of a display device using a hand or an object. That is, the touch screen converts a contact position directly touching a human hand or an object into an electrical signal, and receives a selected instruction from the contact position as an input signal. Such a touch screen can replace a separate input device (such as a keyboard or a mouse) connected to a display...
