    Abstract: The present disclosure provides an organic light emitting component. The organic light emitting component includes 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: The present disclosure provides an OLED display motherboard and a method for manufacturing the same, a method for manufacturing the OLED display panel, and an OLED display device thereof. The OLED display motherboard includes a base substrate having a display region and a non-display region surrounding the display region, a TFT and an OLED device located within the display region of the base substrate, at least two crack stop slits located within the non-display region of the base substrate, an extending direction of the crack stop slit being the same as an extending direction of an edge of the display region of the base substrate, and adjacent crack stop slits being separated by a crack stop slit step, and an encapsulation layer covering the crack stop slit and the OLED device. A portion of the encapsulation layer has a non-uniform thickness.

    Abstract: Disclosed is a display substrate including a base substrate, and a power signal line and an electrode block that are disposed on the base substrate, the electrode block covering at least one side of the power signal line. The base substrate has an encapsulation area. An orthographic projection of the power signal line on the base substrate extends out of the encapsulation area from an interior of the encapsulation area, and an orthographic projection of the electrode block on the base substrate overlaps the encapsulation area. By covering a side of the power signal line in the encapsulation area with the electrode block, the present disclosure can prevent the side of the power signal line covered with the electrode block from being drill-etched, thereby improving the encapsulation reliability of the display substrate.
