  • Patent number: 10761372
    Abstract: An image display apparatus includes: a display panel; a back frame including a flat portion and a side wall; light sources arranged in rows and columns at substantially equal intervals in the flat portion; support pins arranged in rows and columns at substantially equal intervals in the flat portion and away from the light sources; a diffuser panel diffusely emitting light from the light sources toward the display panel; and a luminance-equalizing sheet that is supported on the support pins, between the diffuser panel and the back frame, has an outer edge substantially overlapping an outer edge of an active area of the display panel, and transmits part of the light from the light sources toward the diffuser panel. The luminance-equalizing sheet protrudes in a curved manner toward the side wall between the diffuser panel and the side wall such that distance to the back frame gradually decreases outward.

  • Patent number: 10580346
    Abstract: A display device includes: a display panel that displays an image; a plurality of mount boards having long-length shaped disposed along the display panel; and light emitting elements arrayed on each of the plurality of mount boards in a longitudinal direction of each of the plurality of mount boards. The light emitting elements emit light toward the display panel from behind the display panel, and are arranged in a matrix shape along the display panel. The display device further includes: a back surface board on which the plurality of mount boards is stuck by an adhesive member; and a reflective sheet mounted to the back surface board. The reflective sheet has holes that allow the light emitting elements to pass through at positions corresponding to the light emitting elements, and reflects the light emitted from the light emitting elements toward the display panel. Each of the plurality of mount boards is constituted of a flexible wiring board.

  • Publication number: 20170351145
    Abstract: A display device includes a display panel that displays an image, a plurality of light-emitting sources, a back plate to which the light-emitting sources are mounted, and a reflection sheet. The plurality of light-emitting sources radiates light toward the display panel from a back surface side of the display panel, and is arranged in a matrix along the display panel. The reflection sheet is attached to the back plate, provided with insertion holes into which the light-emitting sources are inserted, and reflects light radiated from the light-emitting sources. The back plate has a plurality of protrusions that causes portions of the reflection sheet to bulge out toward the display panel with the reflection sheet being attached to the back plate.
