  • Patent number: 10860277
    Abstract: A coupled display device includes a first display unit and a second display unit arranged adjacent to each other and coupled. The first display unit includes a first display portion and a first frame portion including two first linear sections and two second linear sections perpendicular to the first linear sections. The second display unit includes a second display portion and a second frame portion including two third linear sections and two fourth linear sections. The first display unit is set in a first position. The second display unit is set in a second position that is inverted from the first position. The first linear sections and the third linear sections extend in an arrangement direction in which the first display unit and the second display unit are arranged. The second linear sections and the fourth linear sections extend in a direction perpendicular to the arrangement direction.

  • Patent number: 10732920
    Abstract: A coupled display device includes display units, and a coupling component, retaining components. The display units are arranged adjacent to each other. The display units include fixers. The coupling component is disposed astride the display units to couple the display units together. The retaining components are fixed to the fixers to retain the display units and the coupling component. In the coupled display device, the fixers are point symmetric to each other with a point of symmetry at a center of a corresponding one of the display units.

  • Publication number: 20130278650
    Abstract: In the present display device, LEDs are controlled to be lit up in an alternating manner where BG-LEDs (34) and BR-LEDs (35) are controlled to be lit up alternatingly every half of one frame period, such that only G display elements are used for display in a first subframe where the BG-LEDs (34) are lit up, and only B and R display elements are used for display in a second subframe where the BR-LEDs (35) are lit up. As a result, even in the case where crosstalk occurs (with respect to color filters of a certain color), display elements of colors for which such crosstalk can be inhibited or eliminated are simply used for display so that a reduction in color reproducibility can be inhibited or eliminated.
