プのＬＥＤ表示器が開発されている。2. Description of the Related Art In recent years, an LED display has come to be used as a display plate used as an information transmission means. The conventional LED display was mainly used indoors in many cases, but recently, a high brightness type LED display that can be used outdoors has been developed.

FIG. 2 is a front view of a conventional unitized LED display, in which 256 LEDs 2 are arranged in 16 rows and 16 columns in a grid pattern of rows and columns, and any of these LEDs can be selectively selected. The letters and figures are displayed by turning on.

In the LED display, a partition plate 1 for preventing light leakage to adjacent dots is provided for each display point (dot), and the partition plate 1 has a hole 3 for inserting the LED 2. At the same time as the opening, an eaves 4 is provided above the hole 3 for the purpose of preventing sunlight from directly hitting the LED 2 and obscuring the display due to sunlight. As the material for the eaves, a resin such as polycarbonate having excellent outdoor weather resistance is used. Receiving a signal from an electric circuit, each LED emits light of red, green, and orange (simultaneous lighting of red and green), and can display characters and figures.

には透明パネル６が太陽光を反射するため、特定の方向
では、かえって、視認性が妨げられる。However, in the conventional LED display device, when the eaves 4 is made of polycarbonate resin, rainwater collects on the eaves 4 as water drops 5 due to surface tension when the eaves 4 is made of polycarbonate resin. The light emitted from is disturbed by the refracting action of the water droplets 5 and becomes difficult to see from below (arrow), which hinders its visibility. Therefore, as shown in FIG. 4, a transparent panel 6 is provided on the front surface of the eaves 4 to prevent rainwater from directly hitting the eaves 4 of the LED display and ensure visibility in rainy weather. I am trying. In the case of such a conventional LED display device, when a large number of the LED display devices are arranged side by side to form a large screen, a large transparent panel 6 that is seamless is required to ensure clear visibility, and the manufacturing cost is high. It was something. Further, since the transparent panel 6 reflects sunlight during fine weather, the visibility is rather hindered in a specific direction.

A hole through which the LED 2 is inserted is formed in the partition plate 1, and an eaves 4 is provided above the hole for the purpose of blocking sunlight and preventing the light emitted from the LED 2 from being offset and weakened. ing.

なお、実施例では、太陽光の反射を防止して明瞭なコン
トラストを得るために、黒色の合成繊維７を使用した。On the surface of the eaves 4, fine synthetic fibers 7 having a length of about 0.5 mm and a thickness of about 1.5 denier and excellent in weather resistance are adhered by electrodeposition processing on the adhesive surface. . The adhesion of the fibers 7 is called flocking (flocking) and makes the surface of the eaves 4 hydrophilic or water-absorbent. As a result, in rainy weather, rainwater does not infiltrate between the fibers 7 and does not become polka dots, and the visibility from below (arrow) is not impaired.
In the examples, black synthetic fibers 7 were used to prevent sunlight reflection and obtain clear contrast.

用いられる。For coloring synthetic fibers, sulfur dyeing is preferred for the purpose of ensuring weather resistance. In addition, the surface of the eaves 4 was previously coated with a metallic material, and static electricity was applied to the surface of the eaves 4 to facilitate the electrodeposition of the synthetic fiber 7. Further, as the adhesive for adhering the fine synthetic fibers 7 to the surface of the eaves 4, a two-component mixed type polyurethane resin is used.

器前方からの視認性がそこなわれることがない。In the above embodiments, the description has been made on the premise that water drops are formed on the upper surface of the eaves. However, this is the same as the fact that the visibility of the LED on the lower side of the eaves is obstructed even if water drops are attached to the lower surface of the eaves. Is. In the present invention, the water is impregnated between the fibers due to the flocking process even for the water droplets on the lower surface of the eaves, and the visibility from the front of the LED display is not impaired.
