【考案の詳細な説明】
本考案は薄型で明るく広い表示面を有する発光
ダイオード表示器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light emitting diode display having a thin, bright and wide display surface.
従来カセツトテープの背面照明等、厚みがうす
くしかも比較的広い面積を明るく均一に照射する
発光ダイオード表示器に於ては、、第１図に示す
ように発光ダイオード１８を反射枠１４で囲み、
その中に透明樹脂１９を注入したあと突出した表
示面１２を有する着色透明カバー１３を設けてい
た。ところがこのような構造では単に部品点数が
多く組立てが煩雑であるばかりでなく、透明樹脂
１９が反射枠１４と発光ダイオード１８の載置台
１６とのすき間等から樹脂漏れを生じ、外形がく
ずれたり樹脂を伝つて光漏れを生じるため歩留ま
りが著しく悪かつた。 Conventionally, in light emitting diode displays that are thin and illuminate a relatively wide area brightly and uniformly, such as backlighting of cassette tapes, the light emitting diode 18 is surrounded by a reflective frame 14 as shown in FIG.
After a transparent resin 19 was injected into it, a colored transparent cover 13 having a protruding display surface 12 was provided. However, in such a structure, not only is there a large number of parts and assembly is complicated, but also the transparent resin 19 leaks from the gap between the reflective frame 14 and the mounting table 16 of the light emitting diode 18, causing the outer shape to collapse and the resin to deteriorate. The yield was extremely poor due to light leakage.
これを改めるため、透明樹脂１９と着色透明カ
バー１３等を成型品とすればよいが、反射枠１４
に相当する部品が困難であつた。即ち白色塗料等
を塗布しようとすると表示面１２をマスクしても
表示面１２に塗料がしみ出したり塗料が成型品の
一部、とりわけ表示面１２周縁の段部にたまるの
で好ましくない。また上記成型品にそのまま反射
枠相当の樹脂を２色成型しようとすると上記成型
品の周囲を金型のすき間に沿つて反射枠樹脂がし
み込むので発光ダイオードの光が成型品の中に入
るのを阻害する事になる。 In order to correct this, the transparent resin 19, the colored transparent cover 13, etc. may be made of molded products, but the reflective frame 14
It was difficult to find parts corresponding to the above. That is, if a white paint or the like is to be applied, even if the display surface 12 is masked, the paint may seep onto the display surface 12 or accumulate on a part of the molded product, particularly on the stepped portion of the periphery of the display surface 12, which is undesirable. Also, if you try to mold two colors of resin equivalent to the reflective frame onto the above molded product, the reflective frame resin will seep around the molded product along the gaps in the mold, preventing the light from the light emitting diode from entering the molded product. It will hinder it.
また、表示面１２を突出させないで、透明樹脂
１９の側面を直接表示面とすると全体が直方体と
なり、外形のくずれや樹脂のしみこみもほとんど
なくすることができる。しかし発光ダイオード１
８の素子は一辺0.2〜0.4mmと小さいので、表示面
では中央部分が高輝度になり、端部が低輝度と輝
度ばらつきが大きくなる。言いかえると、表示面
を突出させると、光路長を長くすること。及び表
示面の裏側に光溜めを設けることという作用を有
するので、これを取り除くと大きい表示面になれ
ばなるほど輝度むらが大きくなり不都合である。 Further, if the display surface 12 is not protruded and the side surface of the transparent resin 19 is directly used as the display surface, the entire display becomes a rectangular parallelepiped, and distortion of the outer shape and seepage of the resin can be almost eliminated. However, light emitting diode 1
Since the element No. 8 is small with a side of 0.2 to 0.4 mm, the central part of the display screen has high brightness and the edge parts have low brightness, resulting in large brightness variations. In other words, protruding the display surface lengthens the optical path length. It also has the effect of providing a light reservoir on the back side of the display surface, so if this is removed, the larger the display surface becomes, the more uneven brightness will become, which is inconvenient.
本考案はこのような点を考慮してなされたもの
で、以下本考案を実施例に基づいて詳細に説明す
る。 The present invention has been devised in consideration of these points, and will be described in detail below based on examples.

まれた透明樹脂である。 FIG. 2 is a perspective view of a light emitting diode display according to an embodiment of the present invention. 1 is a display surface 2 that protrudes from the side
It is a translucent resin having a notch 3 at the bottom, and is lightly colored or kneaded with a light scattering agent as required. 4 is an opaque resin integrally molded to cover the display surface 2 of the translucent resin 1 except for the display surface 2, and is made white by kneading pigments etc. so that it has good light reflectivity especially for the inside. An insertion port 5 is provided to communicate with the notch 3. Reference numerals 6 and 7 designate lead tongues, on the top of which a light emitting diode 8 made of gallium phosphorous or the like is placed and wired. It is inserted into the insertion port 5. Reference numeral 9 denotes a transparent resin embedded in the insertion opening 5 for fixing the lead tongues 6, 7, etc.

３の略中央に位置させた発光ダイオード８の光は
極めて効率よく表示面に誘導できる。 Since the present invention has the structure described above,
In particular, when integrally molding the opaque resin 4, a mold 10 with a roughened tip is applied to the notch 3 of the translucent resin 1 as shown in FIG. By pulling it out, the opaque resin that has adhered and hardened to the inner wall of the notch 3 can be scraped off. Furthermore, by making the bottom of the translucent resin 1 arch-shaped, light can be directed toward the display surface 2, so that the light from the light emitting diode 8 located approximately at the center of the notch 3 can be guided to the display surface extremely efficiently.

留まりの良い表示器となりしかも表示は明るい。 As described above, the present invention includes a translucent resin having a display surface protruding from the side and a notch at the bottom, and an insertion opening that covers the periphery of the translucent resin and communicates with the notch. Since it is a light emitting diode display comprising an opaque resin integrally molded with a resin and a light emitting diode inserted into the insertion slot, it is a thin display with high yield and a bright display.
