Problems solved by technology
[0013] First, when the organic light emitting display panel and the touch screen are formed independently, and the touch screen is then attached to the organic light emitting display panel, the organic light emitting display panel and the touch screen require separate glass, thus resulting in increased hardness and thickness, and making it thin and Realization of flexible organic light-emitting displays becomes impossible
[0014] Second, organic light emitting display panels and touch screens have different panel shapes, thus complicating the process of forming these components and thus reducing yield and price competitiveness
Here, relatively small conductive balls may have contact defects due to the difference in diameter from normal conductive balls
Furthermore, the compression level of the conductive balls changes according to the pressure applied during bonding and thus contact defects may occur during bonding

Embodiment Construction
[0057] Reference will now be made in detail to the preferred embodiments of the present 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.
[0058] Hereinafter, an organic light emitting display and a method of manufacturing the organic light emitting display will be described in detail with reference to the accompanying drawings.
[0059] The organic light emitting display according to the present invention has a touch sensing function and has reduced thickness and increased flexibility. According to the present invention, the thin film transistor and the organic light emitting array are formed on the first substrate, and the touch electrode array is formed on the second substrate. The first and second substrates are bonded together, and then the hard and thick first and second substrates are removed by laser irradiation or etching to...

Disclosed are an organic light emitting display capable of achieving thin film shape and flexibility and exhibiting excellent contact characteristics in a touch pad based on an improved structure, and a method of manufacturing the same, wherein the touch pad A distance between an outermost surface of the touch pad portion and an outermost surface of the dummy pad portion in the pad portion is smaller than a distance between an outermost surface of an adjacent portion adjacent to the touch pad portion and the dummy pad portion. The distance between the outermost surfaces of the pad portions.
Description
technical field [0001] The present invention relates to an organic light emitting display capable of achieving a thin film shape and flexibility, and more particularly, an organic light emitting display capable of achieving a thin film shape and flexibility, and based on an improved structure in touch Excellent contact characteristics are exhibited in the pad. Background technique [0002] Examples of flat panel displays include liquid crystal displays (LCDs), organic light emitting displays (OLEDs), plasma panels (PDPs), quantum dot panels (QDPs), field emission displays (FEDs), electrophoretic displays (EPDs), and the like. These displays include a flat display panel that usually realizes an image as an essential component. Such a flat display panel has a configuration in which a pair of transparent insulating substrates are joined so that they face each other via a layer containing a material that emits light or polarizes light in nature or other optical materials interp...
