  • Publication number: 20240113272
    Abstract: A method of mounting light emitting devices on a mounting board including steps of forming the light emitting devices spaced apart from one another on a first surface of a substrate, forming a mask pattern on a second surface of the substrate opposite to the first surface, the mask pattern exposing regions of the second surface of the substrate that overlap the light emitting devices to be separated from the substrate, and performing a selective laser lift-off process using the mask pattern to mount the light emitting devices to the mounting board.

  • Patent number: 11935912
    Abstract: A display apparatus including a thin film transistor (TFT) substrate; a first LED sub-unit, a second LED sub-unit, and a third LED sub-unit; first, second, third, and fourth electrode pads disposed between the TFT substrate and the first LED sub-unit; and connectors connecting the first, second, and third LED sub-units to a respective one of the electrode pads, in which the first, second, and third sub-units are configured to be independently driven; light generated from the first LED sub-unit is emitted to the outside of the display apparatus by passing through the second and third LED sub-units; light generated from the second LED sub-unit is emitted to the outside of the display apparatus by passing through the third LED sub-unit; and at least one of the connectors includes a first portion electrically connecting a first surface of the first LED sub-unit to the second electrode pad.

  • Patent number: 11923348
    Abstract: A light emitting diode pixel for a display includes a first subpixel including a first LED sub-unit, a second subpixel including a second LED sub-unit, a third subpixel including a third LED sub-unit, and a bonding layer overlapping the first, second, and third subpixels, in which each of the first, second, and third LED sub-units includes a first type of semiconductor layer and a second type of semiconductor layer, each of the first, second, and third LED sub-units is disposed on a different plane, and light generated from the second subpixel is configured to be emitted to an outside of the light emitting diode pixel by passing through a lesser number of LED sub-units than light generated from the first subpixel and emitted to the outside.

  • Patent number: 7573681
    Abstract: An HGA protecting method and member and method of implementing the protecting method and member in a hard disk drive. The HGA includes an actuator, at least one pair of suspensions coupled to the actuator, a flexure having a stationary end fixed to each of the suspensions and a free end, and a slider attached between the stationary end and the free end of the flexure. The HGA protecting member may include a finger restricting excessive movement of the suspension. The finger may further have a flexure supporting portion supporting the free end of the flexure. The HGA protecting member may also be a removable assembly that may be removed after the HGA after assembly of the hard disk drive is complete.

  • Patent number: 5696648
    Abstract: A sealing device for a hard disk drive for easily assembling a base and a cover to be sealed to each other. The sealing device of the hard disk drive including a base and a cover assembled with the base includes a side wall extending upwardly from the edge of the base. A step is recessed by a constant width and length from an upper portion of the side wall. A side surface extends downwards from the edge of the cover in order to be positioned in the step of the side wall of the base. A gasket is installed between the inside of the side surface of the cover and upper portion of the side wall of the base upon assembling the base and the cover.
