Image display device, panel and panel manufacturing method

摘要

Provided are an image display device in which a desired number of panels are combined so that a large light-emitting surface is realized, a panel provided in the image display device, and a method for manufacturing the panel. For this purpose, a panel (11) of the present invention includes a rectangular light-emitting section (13); a substrate (12) having a flat surface (12a′) on which the rectangular light-emitting section (13) is provided and a curved adjacent surface (12b′) that is adjacent to one of edge portions of the flat surface which extend along long sides of the rectangular light-emitting section (13); and a terminal group that is drawn out from a long side of the rectangular light-emitting section (13) and that is disposed in the adjacent surface. The panels (11) are connected to each other by linking edge portions of the flat surfaces (12a′) of the respective substrates (12) so that longitudinal directions of the respective rectangular display sections (13) are parallel to each other and so that the adjacent surface (12b′) is located on the back side of the substrate (12). In an image display section, pixels (50) are arranged in a matrix, and sub-pixels in each of the pixels (50) are aligned in a column direction of the matrix.

主权项

1. An image display device comprising a plurality of panels,
the plurality of panels each including: a rectangular light-emitting section in which a plurality of pixels each including a plurality of light-emitting elements are provided, the plurality of light-emitting elements having a first electrode and a second electrode and emitting light as a result of electric current supply or voltage application; a base member having a flat surface on which the rectangular light-emitting section is provided and an adjacent surface that is adjacent to one of edge portions of the flat surface which extend along a pair of long sides of the rectangular light-emitting section, the base member being curved or bent in the adjacent surface in a direction in which the flat surface is warped outwards; a first terminal group drawn out from the first electrode of the rectangular light-emitting section, the first terminal group being formed in the adjacent surface; and a second terminal group drawn out from the second electrode of the plurality of light-emitting elements, the second terminal group being formed on the flat surface along one of a pair of short sides of the rectangular light-emitting section, the plurality of panels including a first panel and a second panel that is different from the first panel, the first panel and the second panel being connected to each other by linking one of the edge portions of the flat surface of the first panel and one of the edge portions of the flat surface of the second panel so that (i) the light-emitting section of the first panel and the light-emitting section of the second panel are disposed in a same direction and (ii) a longitudinal direction of the light-emitting section of the first panel is parallel to that of the light-emitting section of the second panel, the light-emitting sections of the plurality of panels being combined to constitute an image display section in which the plurality of pixels are arranged in a matrix, the plurality of light-emitting elements included in each of the plurality of pixels being aligned in a column direction of the matrix, the image display device further comprising: a scan driving circuit connected to one of the first terminal group and the second terminal group which one is drawn out in a row direction of the matrix, the scan driving circuit outputting a scanning signal which sets the plurality of light-emitting elements to a selection state; and a data driving circuit connected to one of the first terminal group and the second terminal group which one is drawn out in the column direction of the matrix, the data driving circuit supplying a data signal to the plurality of light-emitting elements set to the selection state by the scanning signal.
