Description

[Detailed description of the invention] Industrial application field The present invention relates to a unit display that constitutes one section of an electronic display device installed in stadiums, streets, etc. etc. are displayed.

Conventional configuration and problems The unit display of a conventional electronic display device consists of a plurality of bar-shaped unit displays in which a large number of light emitting elements are arranged through sockets on the front side, and a column fixed at right angles to the back side. However, it is difficult to position the unit display body and the column relative to each other before fixing them, and since the unit display body does not include the control circuit for the light emitting element, it must be distributed externally. There were problems such as the large number of cables and the troublesome handling of them.

Purpose of the invention This invention fundamentally solves these problems,
The object of the present invention is to provide a unit display for an electronic display device that is extremely easy to assemble as a unit display device, easy to install as an electronic display device, and can drastically reduce the number of cables. be.

Composition of the Invention In order to achieve these objects, the present invention provides a unit display body in which a large number of light emitting elements are arranged in the front part, and a control circuit section of the light emitting elements is housed in the rear part narrower than the front part. A unit display for an electronic display device is constituted, wherein the rear part is slid and stored in the guide portions of storage plates provided on both sides, and fixed by fixing means provided on the storage plates, further comprising: The fixing means is a fixing screw screwed onto the rear end of the unit display through a bent portion formed by bending the rear edge of the storage plate inward.

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. A is a unit display body, the outer part 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 a control circuit section for the light emitting elements 2 is arranged in the rear part, which is narrower than the front part. 3 is stored. More specifically, the light emitting elements 2 are R (red), G (green), and B
The three primary colors of light (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 in the horizontal direction. Further, an L-shaped fixing plate 4 is attached to the rear part. 5 and 5' are paired storage plates,
It is formed of a metal plate, and has guide pieces 6, 6' bent inwardly at the upper and lower edges, and bent parts 7, 7' whose rear end edges are bent inwardly, and is welded to the inner surface. Guide tool 8 with a U-shaped cross section fixed with etc.
8', and the storage plates 5, 5' are unit display units a.
The rear part is provided on both sides of the rear part of the guide piece 6, 6' or the guide tool 8,
It is made up of a fixing screw that is slid into the guide part 8' and stored, and is screwed to the rear end of the unit display a by passing through the bent parts 7 and 7' and screwing it to the fixing plate 4. It has fixing means 9. Reference numeral 10 denotes a column, and when an electric display device is constructed by arranging unit displays A consisting of a unit display body a and storage plates 5 and 5' vertically and horizontally, the storage plate 5- of the unit display A adjacent in the horizontal direction 5', and the holes 11 in the storage plates 5 and 5'
A fixing screw 12 passing from the inner surface is screwed into the
A unit display A is fixed to a support 10. The storage plates 5, 5' may be box-shaped, with the top and bottom sides closed and only the front and back sides open. In addition, when actually carrying out construction work, the storage plates 5 and 5' are first fixed to the support column 10, and then the unit display body a is stored and fixed to the storage plates 5 and 5'. This is advantageous for intermediate handling because it can be shipped as a unit display A in which the storage plates 5, 5' and the unit display body a are assembled together.

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 They protrude upward and downward from the upper and lower edges of the display body a, respectively, and can significantly reduce the rise in temperature of the socket 1.
Furthermore, if the height of the storage plates 5, 5' corresponds to the height of the entire electronic display device, the unit display A can be installed in one stage in the vertical direction. Furthermore, although the unit display body a is equipped with the light emitting elements 2 arranged in two rows, the number of rows may be increased, or in the case of a multi-stage arrangement, the storage plate 5 of the single unit display body a, It may be stored and fixed at 5'. In that case, the guide tools 8, 8' become unnecessary.

Effects of the invention The present invention configured as described above has the following excellent effects.

(1) Since the control circuit for the light-emitting elements is housed inside the unit display, multiple wirings to the light-emitting elements can be done within the unit display, and there is no need to route many cables to the outside, making it easier to handle cables. Handling becomes extremely advantageous.

(2) Since the storage plate is provided with a guide portion, the unit display can be easily slid and stored, and the unit display and the storage plate can be advantageously positioned relative to each other prior to subsequent fixation.

(3) Since the rear part of the unit display is narrower than the front part, leave a space between the storage plates fixed on both sides of the rear part and the storage plates of the horizontally adjacent unit display. This is advantageous when fixing to a supporting means such as a column, and since there is no storage plate in the front part, horizontally adjacent unit displays can be directly and closely abutted against each other, and the light emitting elements can be High-density mounting contributes to improved screen quality.
