Abstract

A display device provided with a plurality of display panels, wherein the display device is characterized in that: the display device is provided with a single control unit for controlling the drive of the plurality of display panels, and a rigid substrate extending along one direction, in which a wiring for conveying an output signal from the control unit is formed; the rigid substrate and the plurality of display panels constitute panel groups connected in series via a flexible substrate along a direction perpendicular to the longitudinal direction of the rigid substrate; and the flexible substrate that connects the rigid substrate and the display panel disposed next to the rigid substrate is provided with a source driver.

First claim

1 . A display apparatus comprising:
a plurality of display panels; a single controller configured to control driving of the display panels; and a rigid board elongated in one direction and provided with lines for conveying an output signal from the controller, the rigid board and the display panels being connected in series via flexible boards along a direction orthogonal to a longitudinal direction of the rigid board and thus forming a panel group, the flexible boards including at least one flexible board connecting the rigid board with at least one of the plurality of display panels that is located next to the rigid board, the at least one flexible board having a source driver mounted thereon.

2 . The display apparatus according to claim 1 , wherein
the rigid board is disposed between two display panels among the plurality of display panels.

3 . The display apparatus according to claim 1 , wherein
the plurality of display panels and the rigid board are connected in series via the flexible boards along a thickness direction of the rigid board.

4 . The display apparatus according to claim 1 , wherein
the controller generates signals for displaying a single image in a single screen consisting of the panel group as a whole.

5 . The display apparatus according to claim 1 , further comprising
a connection section configured to connect two ends of the panel group in a connection direction of the rigid board and the display panels.
