[0002] 従来から、発光機能を搭載した表示パネル (以下、発光表示パネルとする。 )として 種々のものが存在しており、例えば、特許文献 1には、光反射凹凸部が裏面に設けら れたアクリルなどよりなる透明榭脂板の側面力 光を入射させ、透明榭脂板の内面反 射作用を利用することにより奥方まで導光し、入射光を光反射凹凸部で表面側に反 射させ、表面の表示部 (表示層）をその反射光が照明する側面照明式表示パネルが 開示されており、このような表示パネルに光源を配置することにより発光機能を搭載し た表示パネルとなる。  Conventionally, there are various types of display panels having a light emitting function (hereinafter referred to as “light emitting display panels”). For example, in Patent Document 1, a light reflection uneven portion is provided on the back surface. The side force of the transparent resin plate made of acrylic or the like is incident and guided to the back by using the inner surface reflection action of the transparent resin plate, and the incident light is reflected to the surface side by the light reflection uneven part.

In the figure, 1 is a light guide, 2 is a light emitting means, 3 is a light source, 3A is a red LED, 3B is a green LED, 3C is a blue LED, 4 is a display layer, 4A is a red light emitting display pattern, 4B is green The light emission display pattern, 4C shows a blue light emission display pattern.
[0019] 導光体 1は、アクリルやポリカーボネート、 ABS、ポリスチレン、アクリルスチレン、ポ リ塩ィ匕ビュルなどの透明榭脂による成形品を用いるとよい。なお、本発明において板 状とは、平板に限定されるものではなぐ 3次元形状を有する薄型の成形品を含むも のであり、例えば家電、音響機器、携帯電話などの小型電子機器の筐体であっても よい。 [0019] The light guide 1 may be a molded product made of a transparent resin such as acrylic, polycarbonate, ABS, polystyrene, acrylic styrene, or polysilicic resin. In the present invention, the plate shape includes a thin molded product having a three-dimensional shape that is not limited to a flat plate. For example, it is a housing of a small electronic device such as a home appliance, an acoustic device, or a mobile phone. There may be.
[0020] 光出射手段 2は、導光体 1の内面反射 (全反射）により奥方まで導びかれた光を表 示層（表示部) 4を形成した面から出光可能に反射させるための手段であり、例えば 図 1に示すように光反射機能をもつ微細な凹凸形状を形成させる。微細な凹凸形状 は、光源力 距離が遠くなるにつれて、疎力 密に変化させることより均等な発光を 得ることができる。  [0020] The light emitting means 2 is a means for reflecting the light guided to the back by the internal reflection (total reflection) of the light guide 1 from the surface on which the display layer (display section) 4 is formed so that the light can be emitted. For example, as shown in FIG. 1, a fine uneven shape having a light reflecting function is formed. The fine uneven shape can obtain uniform light emission by changing the light source power as the distance from the light source increases.
[0021] また、微細凹凸形状はマット調のシボ面を使用したり、微細なマイクロレンズ形状を 使用してもよい。マイクロレンズなどの形状を制御した凹凸形状を用いることにより、 光線の反射特性を高めることができ、より効果的な発光を得ることができる。この微細 凹凸形状は、導光体 1の成形金型にあらかじめ形状を付与しておき、成形時に転写 させるのが一般的である。また、成形金型に直接形状を付与する代わりに、基体シー ト上に微細凹凸形状を設けた形状転写箔を使用し、導光体 1の成形時に金型に前 述の転写箔を挿入し金型面に配置することによって、成形と同時に微細凹凸形状を 成形品に転写してもよい。  [0021] The fine uneven shape may be a matte textured surface or a fine microlens shape. By using a concave / convex shape in which the shape of a microlens or the like is controlled, the light reflection characteristics can be improved, and more effective light emission can be obtained. This fine uneven shape is generally imparted to the molding die of the light guide 1 in advance and transferred during molding. In addition, instead of giving the shape directly to the molding die, a shape transfer foil having fine irregularities on the base sheet is used, and the above-mentioned transfer foil is inserted into the die when the light guide 1 is molded. By arranging it on the mold surface, the fine uneven shape may be transferred to the molded product simultaneously with the molding.
[0022] また、光出射手段 2は、導光体 1の反射面に微細な凹凸形状を形成させるものに限 定されず、導光体 1に光拡散を行なうドット印刷を施したものでもよい。さらに、光出射 手段 2は、上記微細凹凸形状やドット印刷により直接反射させるのではなぐ一旦透 過した後に下部の白色シート等の反射板により表示層（表示部) 4を形成した面から 出光させるものでもよい。 [0022] Further, the light emitting means 2 is limited to one that forms a fine uneven shape on the reflecting surface of the light guide 1. The light guide 1 may be subjected to dot printing that performs light diffusion. Further, the light emitting means 2 emits light from the surface on which the display layer (display part) 4 is formed by a reflecting plate such as a white sheet below after passing through the fine uneven shape and not directly reflecting by dot printing. It may be a thing.
[0023] また、導光体 1の出光面を全面を発光させるのではなく部分的に発光させたい場合 は、発光させるエリアの位置に応じて光出射手段 2を設け、発光させないエリアの位 置に対応した箇所には光出射手段 2を設けない方がよい。これにより光源力 の光を 無駄に発光させることなく有効に使用することができる。  [0023] In addition, in the case where it is desired to emit light partially rather than to emit light entirely on the light guide surface of the light guide 1, the light emitting means 2 is provided according to the position of the area to emit light, and the position of the area where light is not emitted. It is better not to provide the light emitting means 2 at the locations corresponding to. As a result, the light of the light source power can be used effectively without wasting light.
[0024] 光源 3は、発光色の異なる 2以上の LEDを用いることができ、発光色毎に独立して 駆動可能である。なお、ここで「2以上の」とは発光色の数を示すものではなく LEDの 総数である。例えば、 R (赤色）素子及び G (緑色）素子を 1個ずつ配置し、 B (青色） 素子のみ 2個配置して合計 4個の LEDを配置することもできる。使用できる光源 3の 発光色は、 R, G, Bのほかに黄色、オレンジなど多彩である。  [0024] The light source 3 can use two or more LEDs having different emission colors, and can be driven independently for each emission color. Here, “2 or more” does not indicate the number of emitted colors, but the total number of LEDs. For example, one R (red) element and one G (green) element can be arranged, and only two B (blue) elements can be arranged, for a total of four LEDs. In addition to R, G, and B, the light source 3 can be used in various colors such as yellow and orange.
[0025] また、光源 3となる LEDは発光色毎にそれぞれ異なるノ ッケージを導光体 1の入光 部に並べて配置させてもよいが、 LEDパッケージには発光色の異なる R, G, Bなど の素子を一つのパッケージに搭載した製品もある。このような複数の素子をまとめた L EDパッケージを使用することによって、より省スペースな設計ができる。  [0025] In addition, the LED used as the light source 3 may be arranged with different types of light emitting colors arranged in the light incident part of the light guide 1, but the LED package has different light emitting colors R, G, B There are also products that incorporate these elements in one package. A space-saving design can be achieved by using an LED package that integrates such multiple elements.
[0026] さらに、図 1に記載の実施形態においては、光源 3として LEDを使用した力 光源 3 は LEDに限るものではなぐ蛍光灯等を使用してもよい。また、導光体 1の端部にお いては、光源 3を導光体 1の側面又は下部に配置する。  Furthermore, in the embodiment shown in FIG. 1, a force using an LED as the light source 3 The light source 3 may be a fluorescent lamp or the like that is not limited to the LED. Further, at the end of the light guide 1, the light source 3 is disposed on the side surface or the lower part of the light guide 1.
[0027] 表示層 4は、光源 3からの光のうち透過可能な波長の異なる材料力もなる 2以上の 発光表示パターンを有するものである。なお、ここで「2以上の」とは透過可能な波長 の異なる材料の数を示すものではなく発光表示パターンの総数である。例えば、 R( 赤色)光のみ透過する材料及び G (緑色)光のみ透過する材料からなる発光表示バタ ーンをそれぞれ 1個ずつ配置し、 B (青色)色のみ透過する材料からなる発光表示パ ターンを 2個配置して合計 4個の発光表示パターンを配置することもできる。  [0027] The display layer 4 has two or more light-emitting display patterns that also have material forces with different wavelengths that can be transmitted among the light from the light source 3. Here, “2 or more” does not indicate the number of materials having different wavelengths that can be transmitted, but the total number of light-emitting display patterns. For example, one light emitting display pattern made of a material that transmits only R (red) light and one material that transmits only G (green) light is disposed, and a light emitting display pattern made of a material that transmits only B (blue) light. A total of four light-emitting display patterns can be arranged by arranging two turns.
[0028] また、上記発光表示パターンを構成する材料としては、榭脂バインダー中に顔料や 染料などの着色材を含有したものを使用できる。 赤色顔料はブリリアントカーミン 6Bやレーキレッド Cなどのァゾレーキ顔料、バリウム レッド 2B、トルイジンレッド、ブリリアントファーストスカーレット、ナフトールレッド、キナ クリドン顔料、ローダミン 6Gなどがある。 [0028] Further, as a material constituting the light-emitting display pattern, a resin binder containing a coloring material such as a pigment or a dye can be used. Red pigments include azo lake pigments such as brilliant carmine 6B and lake red C, barium red 2B, toluidine red, brilliant first scarlet, naphthol red, quinacridone pigment and rhodamine 6G.
緑色顔料はフタロシアニングリーン、ブリリアントグリーンレーキ、ダイヤモンドダリー ンレーキ、青色顔料はフタロシアニンブルー系顔料、ビクトリアピュアブルー BOトー ナーなどが挙げられる。  Examples of green pigments include phthalocyanine green, brilliant green lake, diamond Darine lake, and blue pigments include phthalocyanine blue pigment and Victoria pure blue BO toner.

[0029] また、上記発光表示パターンを構成する材料として、複数積層された光学薄膜を用 いることもできる。例えば、酸化チタン、酸ィ匕珪素などの無機物をコーティング、デイツ ビング、蒸着法やスパッタリング法などにより複数積層させた光干渉膜をパターンィ匕し て用いる。なお、本発明において光源 3からの光のうち透過可能な波長とは、表示パ ネルに対して垂直な方向に透過可能な波長という意味であり、光学薄膜を透過する ことに屈折した波長につ 、て材料の同異を述べて 、るわけではな!/、。  [0029] Further, as a material constituting the light emitting display pattern, a plurality of laminated optical thin films can be used. For example, an optical interference film in which a plurality of inorganic materials such as titanium oxide and silicon oxide are laminated by coating, dubbing, vapor deposition, sputtering, or the like is used as a pattern. In the present invention, the wavelength that can be transmitted among the light from the light source 3 means a wavelength that can be transmitted in a direction perpendicular to the display panel, and is a wavelength that is refracted by being transmitted through the optical thin film. I'm not talking about the material differences!
[0030] また、表示層 4は、導光体 1の片面に直接印刷や塗装などの方法で設けることがで きる。また、表示層 4は、転写箔ゃインサートフィルムを用いて導光体 1の成形時に金 型に挿入することにより、導光体 1の成形と同時に導光体 1の片面に形成することが できる。また、透明フィルムに表示層 4を形成したものを導光体 1の片面にラミネートし てもよい。  In addition, the display layer 4 can be provided on one surface of the light guide 1 by a method such as direct printing or painting. Further, the display layer 4 can be formed on one side of the light guide 1 simultaneously with the formation of the light guide 1 by inserting it into the mold when the light guide 1 is formed using a transfer foil insert film. . Alternatively, a transparent film in which the display layer 4 is formed may be laminated on one side of the light guide 1.
[0031] なお、上記表示層 4における透過可能な波長の異なる材料の数は、前記光源 3の 発光色の数に対応している必要はない。例えば、赤色 LED力 の光のみを透過する 発光表示パターン、緑色 LEDからの光のみを透過する発光表示パターン、青色 LE Dからの光のみを透過する発光表示パターンのほかに、赤色 LEDからの光と青色 L EDからの光の両方を透過する発光表示パターンを設けてもよい。 [0032] さらに、上記表示層 4における透過可能な波長とは、前記光源 3から発光される波 長領域にまるごと対応している必要はない。例えば、赤色 LEDからの発光される波 長領域の中で緑色に近い側のより狭い領域の波長だけであってもよぐこの場合、発 光表示パターンで表示される発光色は赤色 LEDの発光色とは異なったものになる。 Note that the number of materials having different wavelengths that can be transmitted through the display layer 4 does not need to correspond to the number of emission colors of the light source 3. For example, a light emitting display pattern that transmits only light of red LED power, a light emitting display pattern that transmits only light from green LED, a light emitting display pattern that transmits only light from blue LED, and light from red LED. And a light emitting display pattern that transmits both light from the blue LED may be provided. Furthermore, the wavelength that can be transmitted through the display layer 4 does not have to correspond to the entire wavelength region emitted from the light source 3. For example, in the wavelength range emitted from the red LED, only the wavelength in the narrower region closer to the green may be used. In this case, the emission color displayed in the emission display pattern is the emission of the red LED. It will be different from the color.
[0033] 以上のように構成することにより、上記光源 3が発光色毎に独立して駆動可能であ るので、この光源 3の駆動を選択的に行なうことで随時、導光体 1の出光面における 発光色を変えることができる。本発明において、光源 3の駆動とは、発光、消光、発光 の光量を変化させることなどを意味する。光源 3の駆動は、光源 3へ供給する電気量 を変化させることにより行ってもよぐまた、遮光板やスリットなどを用いる機械的手段 で行ってもよい。この導光体 1の出光面上には透過可能な波長の異なる材料力もな る 2以上の発光表示パターンを有する表示層 4が形成されて 、るので、上記導光体 1 の出光面における発光色によって発光表示させるパターンを選択することができる。 図 1に示す実施形態で赤色 LED3Aのみを点灯させた場合、異なるエリアにそれぞ れ配置された発光表示パターンのうち赤色発光表示パターン 4Aでは R (赤色)光の 波長を吸収しな!ヽので光を透過し赤色発光することができ、その他の緑色発光表示 パターン 4B、青色発光表示パターン 4Cでは R (赤色)光の波長を吸収するため光を 透過しない（図 la参照）。緑色 LED3Bのみを点灯させた場合（図 lb参照）、または 青色 LED3Cのみを点灯させた場合（図 lb参照）〖こも、それぞれ対応した色の発光 表示パターンのみ力も光を透過し、その他の対応しな 、色では光を吸収し透過しな い。つまり、この実施形態では、希望するエリアの発光表示パターンのみを随時選択 して発光表示させることができる。  [0033] With the configuration described above, the light source 3 can be driven independently for each emission color. Therefore, by selectively driving the light source 3, the light output from the light guide 1 can be performed at any time. The emission color on the surface can be changed. In the present invention, the driving of the light source 3 means light emission, quenching, changing the light emission amount, and the like. The light source 3 may be driven by changing the amount of electricity supplied to the light source 3, or may be performed by mechanical means using a light shielding plate or a slit. On the light exit surface of the light guide 1, the display layer 4 having two or more light emitting display patterns having a material force with different wavelengths that can be transmitted is formed. Therefore, the light emission on the light exit surface of the light guide 1 is performed. A pattern to be lit and displayed can be selected depending on the color. When only the red LED 3A is turned on in the embodiment shown in FIG. 1, the red light emission display pattern 4A among the light emission display patterns arranged in different areas does not absorb the wavelength of the R (red) light! It can transmit light and emit red light, and the other green light-emitting display pattern 4B and blue light-emitting display pattern 4C absorb the wavelength of R (red) light and do not transmit light (see Fig. La). When only the green LED3B is lit (see Fig. Lb), or when only the blue LED3C is lit (see Fig. Lb), only the light emission display pattern of the corresponding color also transmits light and other The color absorbs light and does not transmit. That is, in this embodiment, only the light emission display pattern of the desired area can be selected and displayed at any time.
[0034] 図 2は本発明に係る発光機能を搭載した表示パネルの発光表示の別の実施例を 示す模式図である。図 2— 5中、発光表示パターン 4A〜4Cおよびその他の表示部 4 は 100 μ m以下、好ましくは 50 μ m以下の網点を強調して表現している。  FIG. 2 is a schematic view showing another embodiment of the light emitting display of the display panel equipped with the light emitting function according to the present invention. In Fig. 2-5, the light emission display patterns 4A to 4C and other display parts 4 are expressed by emphasizing dots of 100 µm or less, preferably 50 µm or less.
[0035] 図 2に示す実施形態では、透過可能な波長の異なる材料からなる 3つの発光表示 パターン、すなわち晴れマークを表示する赤色発光表示パターン 4Aと、曇りマークを 表示する緑色発光表示パターン 4Bと、雨マークを表示する青色発光表示パターン 4 Cとが同一エリアに混在して配置されている（図 2参照)。この実施形態で赤色 LED3 Aのみを点灯させた場合、同一エリアに混在して配置された発光表示パターンのうち 赤色発光表示パターン 4Aでは R (赤色)光の波長を吸収しな ヽので光を透過し、そ の他の緑色発光表示パターン 4B、青色発光表示パターン 4Cでは R (赤色）光の波 長を吸収するため光を透過しないので晴れマークのみを表示することができる（図 3 参照）。緑色 LED3Bのみを点灯させた場合、または青色 LED3Cのみを点灯させた 場合にも、それぞれ対応した色の発光表示パターンのみ力ゝら光を透過し、その他の 対応しない色では光を吸収し透過しないので、曇りマークのみを表示（図 4参照）、又 は雨マークのみを表示することができる（図 5参照)。 In the embodiment shown in FIG. 2, three light emitting display patterns made of materials having different wavelengths that can be transmitted, that is, a red light emitting display pattern 4A for displaying a clear mark, and a green light emitting display pattern 4B for displaying a cloudy mark, The blue light emitting display pattern 4 C for displaying the rain mark is mixedly arranged in the same area (see FIG. 2). In this embodiment red LED3 When only A is lit, among the light emitting display patterns arranged in the same area, the red light emitting display pattern 4A does not absorb the wavelength of R (red) light, so it transmits light and other Green light emission display pattern 4B and blue light emission display pattern 4C absorb the wavelength of R (red) light and do not transmit light, so only clear marks can be displayed (see Fig. 3). Even when only the green LED 3B is lit or only the blue LED 3C is lit, only the light emission display pattern of the corresponding color transmits light, and the other non-corresponding colors absorb light and do not transmit Therefore, only the cloudy mark can be displayed (see Fig. 4), or only the rain mark can be displayed (see Fig. 5).
[0036] このように発光させる光源 3を変えることで同一エリアにおいて異なった文字や絵を 表示させることができる力 この異なった文字や絵を少しづつ相違するものとすること によりさらに面白い表現も可能となる。すなわち、各色発光表示パターンを位相をず らして連続的に描写したり、連続的に大きさを変えることによって、光源 3の発光色を 強弱をつけて連続的に変化させて発光させた時に、意匠が動いて見えるような効果 をあたえることもできる（図 6参照)。なお、図 6中の矢印は発光表示パターンではなく 、発光表示パターンの移動方向を示している。  [0036] The ability to display different characters and pictures in the same area by changing the light source 3 that emits light in this way allows even more interesting expressions to be made by making these different characters and pictures slightly different It becomes. In other words, when each light emission display pattern is drawn continuously with a phase shift, or by continuously changing the size, the light emission color of the light source 3 is continuously changed with intensity, and the light is emitted. It is also possible to provide an effect that makes the design appear to move (see Figure 6). Note that the arrows in FIG. 6 indicate not the light emission display pattern but the moving direction of the light emission display pattern.
[0037] また、透過可能な波長の異なる材料力もなる発光表示パターンの全てが、異なるェ リアにそれぞれ配置されたりあるいは同一エリアに混在して配置されたりする必要は ない。例えば、両方が組み合わさっていてもよい。  [0037] In addition, it is not necessary that all of the light emitting display patterns that have material forces with different wavelengths that can be transmitted are arranged in different areas or mixedly arranged in the same area. For example, both may be combined.
[0038] また、本発明の発光表示パネルにおいては、導光体 1の表示層 4が形成された面 の発光を必要としない部分に遮光層を形成してもよい。遮光層を形成することにより、 発光表示パターンのコントラストが向上する。遮光層として黒色インキまたは白色イン キなどが挙げられる。また、インキ層を複数重ね合わせることで遮光効果を上げること ができる。  In the light emitting display panel of the present invention, a light shielding layer may be formed on a portion of the light guide 1 on which the display layer 4 is formed that does not require light emission. By forming the light shielding layer, the contrast of the light emitting display pattern is improved. Examples of the light shielding layer include black ink or white ink. Moreover, the light shielding effect can be improved by overlapping a plurality of ink layers.
また、遮光層として金属蒸着などの反射層を形成すれば、発光を必要としない部分 に照射された光線を導光体 1に戻すことができ、これにより光源からの光を無駄に発 光させることなく有効に使用することができる。また、発光表示パネルの最表面にハ ードコート層 5を形成してもよ ヽ（図 1参照)。  In addition, if a reflective layer such as metal vapor deposition is formed as the light shielding layer, the light irradiated to the portion that does not require light emission can be returned to the light guide 1, thereby causing unnecessary light from the light source to be emitted. It can be used effectively without any problems. In addition, a hard coat layer 5 may be formed on the outermost surface of the light emitting display panel (see FIG. 1).
