  • Patent number: 12645116
    Abstract: A backlight assembly and a display device. The backlight assembly includes: a substrate; a plurality of light-emitting elements for emitting light, wherein the plurality of light-emitting elements are disposed on the substrate; and an isolation wall disposed on the substrate, wherein, the light-emitting elements and the isolation wall are spaced apart from each other on the substrate; a height of the isolation wall is greater than a height of the light-emitting element in a first direction which is a direction of thickness of the substrate. The present disclosure does not require the process of adding molding parts on the substrate by disposing the isolation wall on the substrate. The isolation wall and the light-emitting elements are spaced apart from each other to facilitate subsequent replacement and maintenance. The height of the isolation wall is greater than the height of the light-emitting element.
