  • Publication number: 20240099053
    Abstract: A display substrate, a manufacturing method thereof, and a display device are provided. A pixel region is provided with a light emission function layer on a base substrate of the display substrate, and a separation region is provided with at least one first barrier structure. The first barrier structure includes a stopper pattern and a first separation component. A side surface of the first separation component has a recess, and a portion of the light emission function layer extending to the separation region is disconnected on the side of the first separation component. The separation region is provided with an inorganic layer structure on the base substrate. The inorganic layer structure includes multiple stacked inorganic film layers, the stopper pattern is located between two adjacent inorganic film layers and the first separation component is located on a side of the inorganic layer structure away from the base substrate.

  • Publication number: 20210277500
    Abstract: In the method for preparing single crystal superalloy test bars by using a Ni—W heterogeneous seed crystal, on the premise of ensuring that the single crystal superalloy has the required orientation, by reusing the seed crystal, it is achieved that the trouble caused by the need of preparing a new seed crystal when a single crystal superalloy is produced by the seed crystal method every time is avoided, and the production cost is significantly reduced. In the present disclosure, the formation of the stray grains in mushy zone could be avoided by using a Ni—W heterogeneous seed crystal without mushy zone and a built-in corundum tube.
