  • Publication number: 20240297275
    Abstract: A display apparatus includes a display module array including a plurality of display modules that are horizontally arranged in a form of a matrix. Each display module includes a substrate including a mounting surface and a rear surface opposite to the mounting surface; a metal plate bonded to the rear surface and configured to dissipate heat from the substrate; a front cover covering the mounting surface; inorganic light emitting devices electrically connected to the mounting surface; and a color layer between the inorganic light emitting devices and the front cover. The color layer includes a scattering layer through which light emitted from a third inorganic light emitting device passes. Each display module further includes scattering particles provided in the scattering layer and configured to scatter the light emitted from the third inorganic light emitting device and passing through the scattering layer.

  • Patent number: 11205081
    Abstract: An arithmetic apparatus includes: a sensor acquisition unit that collects sensor information about the surroundings of a vehicle; a feature point extraction unit that extracts a feature point of an object; a target point detection unit that expresses the position of the feature point with spatial coordinates and detects it as a target point; a road edge presumption unit that presumes a segment between the target points, which are continuously aligned, as a road edge; and a blockade judgment unit that judges whether or not to cancel the road edge, on the basis of information about an area behind the presumed road edge, which is obtained from the sensor information, where the area behind the road edge is an area opposite the sensor at the other side of the presumed road edge.

  • Patent number: 11133431
    Abstract: An LED, a manufacturing method thereof, and a display device including an LED are provided. Specifically, the disclosure relates to a flip-chip LED with high efficiency including a current confinement structure and a manufacturing method thereof, and a display device including such an LED. In particular, a flip-chip LED according to the disclosure includes a resistive area that surrounds a light-emitting layer and restricts current flow from the light emitting layer to the sidewalls.

  • Publication number: 20090121522
    Abstract: According to a vehicle V equipped with a passenger frame having a small height from the ground level of an embodiment of the invention, the vehicle is equipped with a passenger frame F, to have a height (vehicle height) from the ground level smaller than a vehicle equipped with a common frame F? that is disposed at a distance from side sills S and side frames f of the passenger frame F of the structure are inserted in spaces formed under the side sills S that forms the sides of the bottom of vehicle V. Therefore, the length of the passenger frame F protruding to the ground level is reduced, which reduces the height (vehicle height) of vehicle V from the ground level that is determined by the passenger frame F.
