Abstract: A hanger hanging multiple display modules is provided. Each display module has at least one rolling receiving portion. The hanger includes a hanger base and a first hanging structure disposed on the hanger base and including at least one first hanging slot corresponding to the rolling receiving portion of the display module. A rolling receiving portion of a first display module passes through the first hanging slot to hang the first display module on the first hanging structure. The first hanging slot includes a first guide section extending along a first direction and a second guide section extending along a second direction. The second guide section is connected to the first guide section. The rolling receiving portion reaches a first position by guidance of the first guide section and a second position by guidance of the second guide section. A display device using the hanger is further provided.

Abstract: An assembly-disassembly tool is adapted for assembling and disassembling a lamp board. The assembly-disassembly tool includes a magnetic conductive member and a sliding module. The magnetic conductive member includes a through hole. When the disassembly tool is positioned on the lamp board, the through hole of the magnetic conductive member is aligned with an iron sheet of the light board. The sliding module including a magnet is slidably disposed above the magnetic conductive member along a direction parallel to a top surface of the magnetic conductive member. When the sliding module is located at a first position relative to the magnetic conductive member, the magnet is staggered with the through hole. When the sliding module slides to a second position relative to the magnetic conductive member, the magnet is aligned with the through hole and is configured to magnetically attract the iron sheet of the lamp board.

Abstract: A light-emitting module including multiple light-emitting units and a display device are provided. Each of the light-emitting units includes multiple light-emitting elements. Each of the light-emitting elements includes a first end and a second end. The first ends of the light-emitting elements of a first light-emitting unit and a second light-emitting unit among the light-emitting units are electrically interconnected. The first ends of the light-emitting elements of a third light-emitting unit and a fourth light-emitting unit among the light-emitting units are electrically interconnected. The second end of one of the light-emitting elements of the first light-emitting unit and the second end of one of the light-emitting elements of the corresponding third light-emitting unit are electrically interconnected.

Abstract: Provided is a light emitting module, including multiple light emitting units and a multi-layer board. Each light emitting unit includes multiple light emitting elements and side connectors. Each light emitting element includes first and second ends. The light emitting units are disposed on the multi-layer board. The first and second ends of each light emitting element are connected to the side connectors through multiple through holes of the multi-layer board. The first ends of the light emitting elements of first and second light emitting units are electrically connected to each other. The first ends of the light emitting elements of third and fourth light emitting units are electrically connected to each other. The display device using the light emitting module of the disclosure may conduct the adjacent light emitting units to each other through the side connectors, increasing repair possibility and reducing the scrap uncontrolled rate of the display device.
