  • Patent number: 11869871
    Abstract: Discussed is an apparatus for self-assembling semiconductor light-emitting devices, the apparatus including a fluid chamber to accommodate the semiconductor light-emitting devices, each semiconductor light-emitting device having a magnetic body; a magnet to apply a magnetic force to the semiconductor light-emitting devices while an assembly substrate is disposed at an assembly position of the self-assembly apparatus; a power supply to induce formation of an electric field on the assembly substrate to allow the semiconductor light-emitting devices to be seated at a preset positions on the assembly substrate in a process of moving the semiconductor light-emitting devices due to a change in a position of the magnet; and a fluid injector to shoot a fluid to some of the semiconductor light-emitting devices to allow the some of the semiconductor light-emitting devices seated on the assembly substrate to be separated from the assembly substrate.
    Type: Grant
    Filed: October 8, 2019
    Date of Patent: January 9, 2024
    Assignee: LG ELECTRONICS INC.
    Inventors: Juchan Choi, Jideok Kim, Bongchu Shim, Seulbitna Lee, Kiseong Jeon, Hyunwoo Cho

  • Patent number: 9001507
    Abstract: A mobile terminal is provided. The mobile terminal may include a window that at least partially covers the terminal body and is made of a light transmitting material, a non-transparent portion covering a portion of a surface of the window, a transparent portion provided within the non-transparent portion on the window to form a front image, and a front pattern plate mounted on a case of the mobile terminal to at least partially expose the pattern through the transparent portion.
