  • Publication number: 20210217993
    Abstract: A display device includes a substrate including a plastic layer, a barrier layer, and a display area in which an image is displayed. The display device further includes a light-emitting diode disposed in the display area, a planarization layer, and a pixel definition layer. The planarization layer and the pixel definition layer overlap the light-emitting diode. The display device further includes a thin film encapsulation layer disposed on the pixel definition layer. The thin film encapsulation layer includes at least one inorganic layer. The display device further includes an opening disposed in the display area and penetrating the substrate. The opening includes a protruded portion and a depressed portion, and the barrier layer overlaps at least one of the pixel definition layer and the planarization layer at the protruded portion.

  • Publication number: 20210212956
    Abstract: Biodegradable polymer microparticles bearing a steroid drug and a preparation method therefor. In the method, a steroid drug and a biodegradable polyester-based polymer are dissolved in an organic solvent and sprayed into a low-temperature hydrocarbon solution to form frozen microparticles that are then immersed in a low-temperature, aqueous salt solution to deprive the microparticles of the organic solvent, thereby preparing biodegradable polymer microparticles bearing a steroid drug. The steroid drug or steroid sex hormone drug-bearing biodegradable polymer microparticles were found to have excellent biocompatibility, biodegradability, porosity, and mechanical strength and to release the steroid drug or steroid sex hormone drug for a long period of time.
