[0039] Figure 2 to Figure 7 The large-screen electro-optical device 1 of the first embodiment is shown. Such as figure 2 As shown, the large-screen electro-optical device 1 is configured by combining a plurality of display tiles T for displaying a predetermined area. In this example, the row (horizontal) direction and the column (vertical) direction in which the brick T is two-dimensionally arrange|positioned on the base structure 20 are shown. as described below ( Figure 7 ), showing that brick T can combine different shapes. The foundation structure 20 is fixed to the wall surface by embedding, bolting, lamination, or the like. The base structure 20 can be produced in a workshop, for example. The basic structure 20 is designed when the data of the architectural structure of the installation site is input into the computer system. And there, in figure 2 In , for convenience, the base structure 20 is shown to be slightly larger than the display area (set of T), but bo...

[0059] Figure 8 to Figure 11 It is an explanatory drawing explaining the second embodiment of the present invention.

[0060] In the second embodiment, display tiles are laid on the wall surface without using the foundation structure 20 . Therefore, a signal bus line is built in each display tile, and the signal bus lines of each display tile are connected to each other.

[0061] Such as Figure 8 As shown, in the second embodiment, the display tiles T are arranged in rows and columns, and the display tiles T are connected to form an electro-optical display device 1 with a large screen. An interface unit 61 is provided at one end (short side) of the horizontally wide screen, and transmits image data signals supplied from the outside to the array of display tiles. The signal buses of the individual tiles are connected within the array of display tiles to form one signal bus. At the other end (end side) of the horizontally wide screen, a termination device 71 is provided to...

[0077] Figure 13 and Figure 14 Indicates the third embodiment. In both figures, for and Figure 9 Corresponding parts are assigned the same symbols and descriptions of related parts are omitted.

[0078] In this example, if Figure 13 As shown, the electro-optical device 1 is installed in a structure such as a cylindrical post. The electro-optical device 1 is configured by combining flexible sheet-shaped display tiles T or already bent display tiles T into a cylindrical shape surrounding the outer wall of the structure. In this embodiment, in order to form a display surface without borders and display images, the interface unit 61 and terminal device 71 described above are not provided as a single unit (refer to Figure 8 ), but the same function is built into the specified display tile T.

[0079] Figure 14 A predetermined row (vertical direction) of a plurality of display tiles T assembled in a cylindrical shape will be described, and the second connecting portion ...

Abstract

An electro-optical device that facilitates assembly of the electro-optical device composed of a plurality of display tiles on a wall surface, and its assembly method are provided. It includes a plurality of display tiles, and a foundation structure having a plurality of regions, wherein the foundation structure is equipped with a signal bus for transmitting an image data signal to a first display tile among the plurality of display tiles, and a first connection section that electrically connects the signal bus with the first display tile, and the first display tile is equipped with pixel elements, a signal processing section that generates signals for driving the pixel elements based on the image data signal, and a second connection section that is electrically connected to the first connection section.

Description

technical field [0001] The present invention relates to an electro-optical device, for example, an electro-optical device suitable for large-screen display that is installed along so-called moving walkways in train stations or airports, or installed in theaters or arenas. Background technique [0002] In a direct-view display device with a large screen, for example, in a display device arranged along the passage on the width of the wall of the passage, the number of pixels in the screen is very large, and the number of image data to be processed is huge. Extremely high data processing capabilities are required in the device. For example, video signals are input in dot-sequential or pixel-sequential display based on the premise of a row-sequential display method using a serial-to-parallel converter for one line (1 RAW). Next, as the size of the display screen increases, that is, the amount of frames and data increases, the clock frequency of the input signal also increases s...
