Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display device that can improve display effects by controlling undesired external incident light.

[Technical background of the invention]

2. Description of the Related Art Recently, it has been known that an electronic display board equipped with a large number of light emitting elements is installed as a display device, for example, at the rear of the outfield stands of a baseball stadium, and displays an enlarged view of a television. This light-emitting element has a light-emitting body placed directly inside the medium-thick hood, and a color filter located in front of it. A large number of louver pieces are provided to prevent this.

[Problems with LR quantity technology]

However, in the case of the conventional polar display element, when sunlight has a relatively high XtC, the light incident on the mouth is cut off by the louver, and the display effect due to the light emitting body does not occur. If the temperature becomes low, each louver piece OIa1w
[Important aspect of the invention] The present invention has been made in order to eliminate the above-mentioned drawbacks. An object of the present invention is to provide a display device in which a filter located on the back side of a louver piece is arranged so as to be tilted downward, thereby eliminating unnecessary reflected light and improving visibility. .

[Overview of the invention]

That is, a light emitting body is installed inside, a louver piece is arranged in the front light emitting display opening, and a downwardly sloping 12 filter is installed between the light emitting body and the louver piece in a medium-thick 7-dore. The purpose is to reflect the light incident on the filter to the louver piece or to the Fi ground without affecting the light emission display C1.

[Embodiments of the invention]

The rules of the present invention will be explained below with reference to FIG. (〃 is a luminous body consisting of a rod-shaped rung, (
2) is an aluminum reflective coating, and (S) is a transparent portion. (Shun Hashiya Hikari 7-Card, for example, is made of steel and has a cylindrical shape, and the front facing the light-emitting body (1) has an opening for light-emitting display (5).
) and 12 This opening @ (phrase refers to a large number of louver pieces (6) in which power is distributed in a row).In the case of installation with <j> inside l#, the body (γ) is engaged with the stopper piece (8). C: Therefore, it is attached.

In addition, louver pieces (6) (6) tj upwards 11117
It is arranged with a slanted angle plate of "
4) For installation, the surface of the body (7) and louver pieces (8) (6") are all coated with black matte coating. (9
) #i For example, a colored glass filter with one of the three primary colors, at the connection between the luminous body mountain and the louver piece (a><i>, is approximately downward C-mounted with an inclination angle of lO°, i.e.
The upper part of the filter (9) is a louver piece (・) 4-97
- It fits into the upper part of the hood (4) and is spaced apart from the upper part of the lower l1ilFi in a plow-like manner. , f
may be between 5° and 15°, but preferably
It is.

Next, the functions will be described in detail. FIG. 3 is a schematic explanatory diagram of the functions showing an enlarged view of the display element section.

First, if the sunlight is at an angle of incidence of G() g2, the arrow indicates a high fC; if there is, the incident light will be cut by the louver piece (6) without any problem, but at the angle shown in (a). In the case of (b), the light is reflected to another looper piece (6) and does not interfere with the display of the light emitter ψ. Furthermore, even if the incident angle decreases, the louver piece (6) will reflect the same and will not obstruct the display, and the sunlight will be reflected as shown in (c).
It is possible to maintain a good display effect without interfering with the visibility of the spectators in the infield stands by reflecting it off the ground surface α, as shown in FIG. .

[Effects of the 'fJj proposal]

In the present invention, as described above, the filter between the light emitting body and the louver piece is arranged in a downwardly tilted shape, so that the louver piece I: Therefore, the sunlight can be cut at a low angle below the angle of incidence that can be cut. When the two people sit in front of each other, the light emitted from the filter is controlled so that it is reflected by the louver, or the light is reflected by the ground except for each seat. Good line of sight without affecting the image; has the special advantage of being able to retain the image.
