Abstract: A method of forming a thin film includes preparing a mixture including a light emitting layer material that forms a light emitting layer and a material that forms a layer adjacent to the light emitting layer, and sequentially laminating the light emitting layer and the layer adjacent to the light emitting layer onto a substrate inside a chamber by heating the mixture to a process temperature of the light emitting layer material and a process temperature of the additional material. The light emitting layer material and the additional material have process temperatures that are different from each other. The light emitting layer material and the additional material are laminated onto the substrate sequentially from one of the light emitting layer material and the additional material having a lower process temperature to one of the light emitting layer material and the additional material having a higher process temperature.

Abstract: A method for aging an organic light emitting display includes estimating a lifespan curve of a display panel based on at least one initial aging profile of the display panel, correcting at least one of a target luminance or a target white color coordinates of the display panel such that the estimated lifespan curve corresponds to a target lifespan curve, and setting a lifespan look up table by storing at least one of the correction value of the target luminance or the correction value of the target white color coordinates.
