もコスト高となり不都合である。 Conventionally, in a light emitting diode display device that displays characters, numbers, etc. by surrounding the light emitting diodes 12, 12 with a reflective frame 14 as shown in FIG.
A light diffusion sheet 16 for making the display uniform above the screen and a mask plate 19 for adjusting the outline of the display
However, since light leaks through the light diffusion sheet 16, if the opening (zero) is displayed with a Japanese character-shaped display, for example, At times, it can be mistaken for the real day 8. In order to eliminate this problem, a light diffusing plate may be prepared for each reflective window 15, 15, using a plate-shaped resin molded product, but this is inconvenient as it has poor workability and high cost.
本案はこのような欠点を改めるためになされた

している。 FIG. 2 is a sectional view (a) of a light emitting diode display device according to an embodiment of the present invention, and a plan view (b) of a light diffusion sheet used therein. In the figure, 1 is a printed circuit board made of resin such as paper epoxy or glass epoxy.
Reference numerals 2 and 2 indicate light emitting diodes such as GaP, which are mounted and fixed on printed patterns 3, 3, . . . of the printed circuit board 1. Reference numeral 4 denotes a reflective frame such as a white resin molded product having reflective windows 5, 5 surrounding the light emitting diodes 2, 2, and the upper opening ends of the reflective windows 5, 5 are approximately rectangular, so as to form two diagonal shapes. It is located. 6 is a reflective frame 4 so as to cover at least the upper part of the reflective windows 5, 5.
The light diffusion sheet laid on the surface of the second
As shown in FIG. b, through holes 7, 7, . . . are provided at locations corresponding to the locations where the reflective windows 5, 5 of the reflective frame are adjacent to each other. Reference numeral 8 denotes a colored and transparent outer case, which has a regular outer shape and includes at least a light diffusion sheet 6.

又はこれを十字状に組合せた形状である。 In the above example, if the height of the displayed characters is 15 mm, the reflective windows 5, 5
The size of the opening on the display side is 1.2 mm wide and 7 mm long.
The area where the reflective windows 5, 5, . . . are adjacent to each other has a width of 0.25 to 0.4 mm and a length of 1.5 mm. On the other hand, the light diffusing sheet is made of a polyester resin molded product mixed with a light diffusing agent, etc., and has a thickness of 0.075 to 0.11 mm, and the through holes 7, 7... are rectangular or cross-shaped with a width of 0.2 to 0.3 mm and a length of 3 mm. The shape is a combination of
尚、上述の例において、従来のようにマスク板
を光拡散シート６と外被ケース８の間に挿入して
もよい。 In the above example, a mask plate may be inserted between the light diffusion sheet 6 and the outer case 8 as in the conventional case.

とはない。 As described above, the present invention includes a substrate, a plurality of light emitting diodes placed and fixed on the substrate, a reflective frame having a plurality of reflective windows surrounding the light emitting diodes, and a reflective frame that covers the upper part of the reflective frame. Since it is equipped with a light diffusion sheet having through-holes at the locations corresponding to the areas where the reflection windows are adjacent to each other, and an outer case containing at least the light diffusion sheet, there is no possibility of leakage through the light diffusion sheet. The light propagation is stopped because the transparent holes act as light reservoirs, and it does not illuminate unlit reflective windows to the extent that it may cause misunderstandings.Also, the light diffusion sheet is only one sheet, and the outer cover is Since it is positioned and fixed by the case, manufacturing does not become complicated.
