    Abstract: In a method of measuring a life time of a display panel, pixels each including a first sub-pixel emitting light of a first color are disposed in the display panel. The display panel includes a first region in which at least one pixel including a first sub-pixel emitting light of the first color is located and a second region not overlapping with the first region and having at least one pixel located therein. The method includes a first step in which a first sub-pixel in the first region emits light and a first sub-pixel in the second region does not emit light while the first sub-pixel emits light, and a second step in which a data voltage for displaying an image of the same grayscale is applied to the first sub-pixel located in the first region and the first sub-pixel located in the second region.

    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.
