Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic display device installed in stadiums, streets, etc., which displays images, characters, etc. by controlling a large number of light emitting elements. be.

[Prior art] Prior patent application published after the filing date of the present application
The display device disclosed in No. 161519 (Japanese Unexamined Patent Publication No. 59-50425) has a unit display unit in which a large number of light emitting elements are arranged in the front part, which is fixed to a horizontal arm part extending forward from a frame body behind it. It has been done.

Next, according to Japanese Utility Model Application Publication No. 54-158588, a lead terminal piece is provided in the narrow rear part of the light emitting body in an L-shape projecting from the side surface thereof, and the rear end of the lead terminal piece is Fixing to a substrate is disclosed. Further, according to this publication, it is disclosed that a plurality of light emitters are connected to each other by passing a rod through a hole penetrating both sides of the narrow rear part of the light emitter or a groove provided on the back surface of the narrow rear part. ing.

[Problems to be Solved by the Invention] In all of the above conventional techniques, since the frame or the substrate is behind the unit display or the light emitting body,
It is obvious that there are problems in that it is difficult to fix the unit display bodies or the light emitters in a well-balanced manner, that a considerable amount of back space is required, and that the overall depth of the apparatus becomes longer and the apparatus becomes larger.

Furthermore, the connection of the light-emitting bodies using the bar in Japanese Utility Model Application Publication No. 54-158588 has nothing to do with the structure of the narrow rear part of the light-emitting body, and by making the narrow rear part, the adjacent light-emitting bodies This is not an attempt to advantageously fix the light emitting body by utilizing the space between the narrow rear side surfaces.

The present invention provides an electric display device that can effectively utilize the space between the side surfaces of the narrow rear part of the unit display to fix the unit display in a well-balanced manner and shorten the overall depth of the device, and in particular, The purpose is to adapt it to large-sized electronic display devices in which the back space needs to be as small as possible.

[Means for Solving the Problems] The present invention provides a plurality of unit display bodies in which a large number of light emitting elements are arranged in the front part and has a rear part narrower than the front part, and the adjacent unit display bodies are The electronic display device is characterized in that the unit display body is fixed to a vertical support installed through a space between the side surfaces of the rear part.

[Function] According to the present invention, the space between the rear side surfaces of adjacent unit display bodies can be effectively utilized, and the unit display bodies can be effectively fixed using the vertical support installed through this space. In particular, since the control circuit section of the light emitting element is housed in the unit display body, the unit display body, which is quite long in depth, can be fixed in a well-balanced manner, and the depth of the entire device can be shortened, contributing to miniaturization. In particular, the construction conditions for large-sized electronic display devices in which the back space must be made as small as possible can be significantly relaxed.

[Example] Embodiments of the present invention will be described with reference to the drawings.

In the drawing, a is a unit display body, the outer shell of which is made of synthetic resin, a large number of light emitting elements 2 are arranged in the front part through sockets 1, and the light emitting elements 2 are arranged in the rear part narrower than the front part. A control circuit section 3 is housed therein. More specifically, the light emitting element 2 is R
The three primary colors of light (red), G (green), and B (blue) are arranged in two rows, and the pixels are arranged in an equilateral triangle. Both side edges of the front part of the unit display bodies a are obliquely shaped so that the light emitting elements 2 can be densely mounted when a plurality of unit display bodies a are arranged adjacent to each other. Further, an L-shaped fixing plate 4 is attached to the rear part. Reference numerals 5 and 5' designate a pair of storage plates, which are made of metal plates, and have guide pieces 6 and 6' bent inwardly at the upper and lower edges, respectively, and a bent part 7 whose rear end edge is bent inwardly. , 7', and guide tools 8, 8' having a U-shaped cross section fixed to the inner surface by welding or the like, and storage plates 5, 5' are provided on both sides of the rear part of the unit display a. The rear part thereof is slid into a guide section consisting of guide pieces 6, 6' or guide tools 8, 8', and is then screwed onto the fixing plate 4 through the bent parts 7, 7', respectively. It has a fixing means 9 consisting of a fixing screw. 10 is a vertical support, which is installed through the space between the rear side surfaces of adjacent unit display bodies a;
When a plurality of unit displays A consisting of a unit display a and storage plates 5 and 5' are installed to configure an electronic display device, the unit display A is installed between the storage plates 5 and 5' of adjacent unit displays A, and the storage plates 5 and 5' are installed. The fixing screws 12 leading from the inner surface are screwed into the holes 11 of the plates 5 and 5', and the unit display A
is fixed to the support column 10. In addition, the storage plates 5, 5'
It may be box-shaped with the top and bottom sides closed and only the front and back sides open. Further, although the unit display a has light emitting elements 2 arranged in two rows, the number of rows may be increased, or in the case of a multi-stage arrangement, a single unit display a is mounted on the storage plates 5 and 5. ’ may be stored and fixed. When actually carrying out construction work, first, the storage plates 5, 5' are fixed to the support column 10, and then the unit display a is stored and fixed on the storage plates 5, 5'. In such a case, the storage plates 5, 5' and the unit display body a can be assembled into the unit display A, which can be shipped as a whole, which is advantageous for intermediate handling. Note that air is blown from the rear of the unit display A by an air blower (not shown) and is passed between the unit displays A, so that the cooling of the socket 1 and the light emitting element 2 is promoted, and especially the side edges of the socket 1 are Display body a
The socket 1 protrudes upwardly and downwardly from the upper and lower edges of the socket 1, respectively, and can significantly reduce the temperature rise of the socket 1. Also, if the height of the storage plates 5, 5' is equivalent to the height of the entire electronic display device,
The unit display A only needs to be installed in one stage in the vertical direction.

It goes without saying that light-emitting elements include not only self-emitting incandescent lamps, fluorescent tubes, light-emitting diodes, and cathode ray tubes, but also liquid crystal elements that become equivalent to light-emitting elements when combined with a backlight.

[Effects of the Invention] According to the present invention, the rear part of the unit display body is configured to be narrower than the front part, and the space between the side surfaces of the rear part of adjacent unit display bodies is effectively utilized. ,
The unit display can be effectively fixed by using the vertical support installed through this space, especially when the unit display has a considerably long depth because the control circuit of the light emitting element is housed in the unit display. The device can be fixed well in a well-balanced manner, and the depth of the entire device can be shortened, contributing to miniaturization. In particular, it is effective in significantly easing the construction conditions of a large-sized electronic display device in which the back space needs to be made as small as possible.
