Flexible organic light emitting display and method in an in-cell structure having a touch electrode array for manufacturing the same

摘要

Disclosed are an organic light emitting display that enables realization of a thin film shape and flexibility, and exhibits superior contact properties in touch pads based on an improved structure, and a method for manufacturing the same, wherein a distance between the outermost surface of the touch pad portion and the outermost surface of the dummy pad portion in the touch pad portion is smaller than the distance in a neighboring portion adjacent to the touch pad portion.

主权项

1. An organic light emitting display comprising:
a first buffer layer and a second buffer layer, each having an active region and a dead region and facing each other; a thin film transistor array including a thin film transistor in each of a plurality of pixels defined in a matrix form on the active region of the first buffer layer; an organic light emitting diode connected to each thin film transistor at each pixel; a touch electrode array formed on the active region of the second buffer layer; a touch pad portion formed on a part of the dead region of the second buffer layer; a dummy pad portion facing the touch pad portion on the dead region of the first buffer layer; and a sealant including a plurality of conductive balls between the touch pad portion and the dummy pad portion, wherein a distance between the outermost surface of the touch pad portion and the outermost surface of the dummy pad portion is smaller than a distance between outermost surfaces of neighboring portions adjacent to the touch pad portion and the dummy pad portion.
