Abstract: An organic light emitting component, including a substrate, an intermediate structure layer disposed on the substrate. The intermediate structure layer includes a display area and a non-display area at a periphery of the display area. The intermediate structure layer further includes a planarization layer, and an anti-shrinkage stop structure disposed at the non-display area and a display structure portion disposed at the display area are both disposed on the planarization layer and spaced apart from each other. The organic light emitting component includes a thin film encapsulation structure layer disposed on the surface of the intermediate structure layer facing away from the substrate. The anti-shrinkage stop structure is disposed between the thin film encapsulation structure layer and the planarization layer, and a free end of the anti-shrinkage stop structure extends into the thin film encapsulation structure layer.

Abstract: A back-film structure may include a first back-film portion which serves as a first circle upon rolling and a second back-film portion arranged side by side with the first back-film portion in the rolling direction, wherein a thickness of the first back-film portion increases in the rolling direction. This solution can ensure that the inner surface of the tail end of the first back-film portion is located as close as possible to the inner surface of the head end of the first back-film portion after the rolling.
