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: Disclosed are a method for driving display panel, and a display device. The display panel includes a plurality of pixels arranged in an array, and each pixel includes sub-pixels of at least three colors. The method includes: acquiring a viewing distance between a user and the display panel; determining the number of pixels to be lightened in the display panel based on the viewing distance; wherein, the larger the viewing distance is, the smaller the number of pixels to be lightened in the display panel is; and displaying based on the determined number of pixels to be lightened.
