  • Publication number: 20240098091
    Abstract: Provided is a method performed by a least one computing device for a message service. The method comprises receiving a transmission request for a compound message which is a bundled message comprising a parent message and a plurality of child messages, obtaining permission information for a sender of the compound message, determining whether to allow each of the child messages to be sent based on the permission information and controlling transmission of the compound message based on the determination result.

  • Patent number: 11295972
    Abstract: The present disclosure provides a method for transfer and assembly of RGB micro-light-emitting diodes using vacuum suction force whereby the vacuum state of micrometer-sized adsorption holes to which micro-light-emitting diodes formed on a mother substrate or a temporary substrate are bonded is controlled selectively, so that only the micro-light-emitting diode devices desired to be detached from the mother substrate or the temporary substrate are detached from the mother substrate or the temporary substrate using vacuum suction force and then transferred to a target substrate.
    Type: Grant
