Abstract
Description
本発明は、同一表示面に異なる表示を切り換えて表示させる可変表示構造の技術分野に属する。 The present invention belongs to the technical field of a variable display structure for switching and displaying different displays on the same display surface.
従来においては、第１波長領域の青色光を通過させる第１領域、第２波長領域の緑色光を通過させる第２領域、背景を形成するその他の領域を箔シート後面にプリント印刷し、後方から、青色光の第１光源と緑色光の第２光源で照明している（例えば、特許文献１参照。）。
しかしながら、従来にあっては、色度の差により表示にばらつきが生じていた。また、光源の位置によって全体的に輝度ムラが生じていた。 However, conventionally, the display has been varied due to the difference in chromaticity. Moreover, the brightness nonuniformity has arisen on the whole with the position of the light source.
本発明は、上記問題点に着目してなされたもので、その目的とするところは、第１の課題として、色度による表示のばらつきがない表示にでき、第２の課題として、光源の位置による輝度ムラがない表示にできる可変表示構造を提供することにある。 The present invention has been made paying attention to the above-mentioned problems. The object of the present invention is to provide a display with no display variation due to chromaticity as a first problem, and as a second problem, the position of a light source. It is an object of the present invention to provide a variable display structure that can achieve a display without uneven brightness.
上記目的を達成するため、本発明では、透光性のあるシートに波長の異なる第１光源の光と第２光源の光を切り換えて投光させ、第１表示と第２表示を行わせる可変表示構造であって、前記シートの片面に施された、第１光源の波長のみを透過させる第１印刷部分と、前記シートの前記第１印刷部分を設けた面に施された、第２光源の波長のみを透過させる第２印刷部分と、前記シートの前記第１印刷部分を設けた面に施された、第１光源の波長と第２光源の波長を透過させない第３印刷部分と、前記第１表示と前記第２表示の重複する部分と重なる部分で、第１光源及び第２光源の光を抑制して輝度及び色度を調整する調光印刷部を備えたことを特徴とする。
なお、請求項４における「インキの量」は、特定色のインキの量でも、全体のインキの量であっても含まれるものとする。
In order to achieve the above object, according to the present invention, a light-transmitting sheet is switched so that the light of the first light source and the light of the second light source having different wavelengths are projected, and the first display and the second display are performed. A second light source, which is a display structure, applied to one side of the sheet, the first printed part transmitting only the wavelength of the first light source, and the surface of the sheet provided with the first printed part. A second printed part that transmits only the wavelength of the first printed part, a third printed part that is applied to the surface of the sheet on which the first printed part is provided, and that does not transmit the wavelength of the first light source and the wavelength of the second light source, A dimming printing unit is provided that adjusts luminance and chromaticity by suppressing light from the first light source and the second light source in a portion that overlaps the overlapping portion of the first display and the second display.
Note that the “ink amount” in claim 4 includes both the amount of ink of a specific color and the total amount of ink.
よって、本発明にあっては、第１の効果として、色度による表示のばらつきがない表示にでき、第２の効果として、光源の位置による輝度ムラがない表示にできる。 Therefore, in the present invention, the first effect can be a display with no display variation due to chromaticity, and the second effect is a display without luminance unevenness due to the position of the light source.
以下、本発明の可変表示構造を実現する実施の形態を、実施例１〜実施例４に基づいて説明する。 Hereinafter, embodiments for realizing the variable display structure of the present invention will be described based on Examples 1 to 4.

First, the configuration will be described.
FIG. 1 is a cross-sectional view showing the variable display structure of the first embodiment. FIG. 2 is a front view and a rear view of the color filter having a variable display structure according to the first embodiment. FIG. 3 is a cross-sectional view taken along the line AA in FIG. FIG. 4 is a cross-sectional view of the variable display structure of the first embodiment. FIG. 5 is an explanatory view showing a first display and a second display of the variable display structure of the first embodiment. FIG. 6 is an explanatory diagram showing the relationship between the characteristics of the first printed portion and the second printed portion of the variable display structure of Example 1 and the wavelengths of the first light source and the second light source.
スイッチ１は、まず、矩形枠状のスイッチフィニッシャ２の内部に矩形枠状のガイドハウジング７を設ける（図１参照）。
ガイドハウジング７には、矩形枠状のスイッチフィニッシャ２の開口面から開口面へ向かう方向、つまり、前後面に摺動可能なレール部分を設ける。
スイッチフィニッシャ２及びガイドハウジング７の背面側には、開口を塞ぐ板状の基板６を設ける。
基板６の前面側、つまりスイッチフィニッシャ２の内部側には、波長が約５００nmをピークとする第１光源３と、波長が約６００nmをピークとする第２光源４、押されることによりON/OFFの操作入力を行うタクトスイッチ５を設ける。
First, the switch 1 is provided with a rectangular frame-shaped guide housing 7 inside a rectangular frame-shaped switch finisher 2 (see FIG. 1).
The guide housing 7 is provided with a slidable rail portion in the direction from the opening surface of the rectangular frame-shaped switch finisher 2 to the opening surface, that is, the front and rear surfaces.
A plate-like substrate 6 that closes the opening is provided on the back side of the switch finisher 2 and the guide housing 7.
On the front side of the substrate 6, that is, on the inner side of the switch finisher 2, the first light source 3 having a peak of about 500 nm and the second light source 4 having a peak of about 600 nm are turned ON / OFF by being pushed. A tact switch 5 for performing the operation input is provided.
第１光源３及び第２光源４としては、異なる色を発光するLEDがコスト抑制、メンテナンス性から好ましいが、別のものであってもよい。
次に内外で２重の枠部分を有するスライダ８を設ける。スライダ８の内部の枠部分は、第１光源３及び第２光源４側に行くに従って角錐状に内側が狭くなる形状にする。また、スライダ８の内側の枠形状部分は後方に延長し、第１光源３及び第２光源４の側方を覆うようにする。
さらに、スライダ８の内側の枠形状部分の下方傾斜面には、下方に突出する形状の係合部８ａを設ける。係合部８ａの位置は、下方に移動するとタクトスイッチ５と係合する位置にする。
スライダ８の内側枠部分の前面部分には、カラーフィルタ１０を設ける。
カラーフィルタ１０の前面部分には、消灯時に外光によって印刷パターンが見えてしまうのを防ぐために全体的に透光性が低くされたスモークレンズ１１を設ける。
As the 1st light source 3 and the 2nd light source 4, although LED which light-emits a different color is preferable from a cost control and maintainability, another thing may be used.
Next, a slider 8 having double frame portions inside and outside is provided. The inner frame portion of the slider 8 is formed in a pyramid shape such that the inner side becomes narrower toward the first light source 3 and the second light source 4 side. Further, the frame-shaped portion inside the slider 8 extends rearward so as to cover the sides of the first light source 3 and the second light source 4.
Furthermore, an engaging portion 8 a that protrudes downward is provided on the downwardly inclined surface of the frame-shaped portion inside the slider 8. The position of the engaging portion 8a is set to a position where it engages with the tact switch 5 when moved downward.
A color filter 10 is provided on the front surface portion of the inner frame portion of the slider 8.
A smoke lens 11 having a generally low translucency is provided on the front surface of the color filter 10 in order to prevent the printed pattern from being seen by external light when the light is turned off.
ここで、スモークレンズ１１、カラーフィルタ１０を取り付けたスライダ８を、ガイドハウジング７のレール部分に係合させて前後に摺動自在にする。
これにより、スライダ８をタクトスイッチ５に向かって押すと、スライダ８が摺動して傾斜面から下方に突出する形状の係合部８ａがタクトスイッチ５を押す構造にする。
また、押された後に、自由状態にすると、タクトスイッチの反力で戻る構造にする。
Here, the slider 8 to which the smoke lens 11 and the color filter 10 are attached is engaged with the rail portion of the guide housing 7 so as to be slidable back and forth.
Thus, when the slider 8 is pushed toward the tact switch 5, the slider 8 slides and the engaging portion 8a having a shape protruding downward from the inclined surface pushes the tact switch 5.
Moreover, when it is set in a free state after being pushed, it is structured to return by the reaction force of the tact switch.
カラーフィルタ１０は、透明なシート１０ｇ前面に、第１印刷部分１０ｂ、第２印刷部分１０ｃ、重なり部分１０ｄ（無印刷部分）、背景印刷部分１０ｅを設け、シート後面に拡散印刷部１０ａ、調光印刷部分１０ｆを設ける。
ここで、第１表示１２を図５(a)に示すように文字の「Ａ」、第２表示１３を図５(b)に示すように文字の「Ｅ」とする。
第１印刷部分１０ｂは、第１表示１２である「Ａ」の第２表示１３「Ｅ」と重ならない図２(a)の部分であり、赤色光を通過させる赤い色の印刷である。この第１印刷部分１０ｂの波長に対する透過効率の特性は、図６の線２１で示す特性となる。
The color filter 10 is provided with a first printed portion 10b, a second printed portion 10c, an overlapping portion 10d (non-printed portion), and a background printed portion 10e on the front surface of the transparent sheet 10g. A printing portion 10f is provided.
Here, the first display 12 is the character “A” as shown in FIG. 5A, and the second display 13 is the character “E” as shown in FIG. 5B.
The first print portion 10b is a portion shown in FIG. 2A that does not overlap with the second display 13 “E” of “A” that is the first display 12, and is a red color print that allows red light to pass therethrough. The characteristic of the transmission efficiency with respect to the wavelength of the first printed portion 10b is the characteristic indicated by the line 21 in FIG.
第２印刷部分１０ｃは、第２表示１３である「Ｅ」の第１表示１２「Ａ」と重ならない図２(a)の部分であり、青色光を通過させる青い色の印刷である。この第２印刷部分１０ｃの波長に対する透過効率の特性は、図６の線２３で示す特性となる。
重なり部分１０ｄは、第１表示１２の「Ａ」と第２表示１３の「Ｅ」とが重なった部分である。実施例１では、第１印刷部分１０ｂ、第２印刷部分１０ｃを施すシートの前面には、何も印刷しない。つまり、前面の重なり部分１０ｄには何も印刷せず、印刷は後面に行う。
The second print portion 10c is a portion of FIG. 2A that does not overlap the first display 12 “A” of “E” that is the second display 13, and is a blue print that allows blue light to pass through. The characteristic of the transmission efficiency with respect to the wavelength of the second printed portion 10c is the characteristic indicated by the line 23 in FIG.
The overlapping portion 10d is a portion where “A” in the first display 12 and “E” in the second display 13 overlap. In Example 1, nothing is printed on the front surface of the sheet on which the first printing portion 10b and the second printing portion 10c are applied. That is, nothing is printed on the overlapping portion 10d on the front surface, and printing is performed on the rear surface.
第１印刷部分１０ｂと第２印刷部分１０ｃは、実際に表示する第１表示１２及び第２表示１３よりやや幅広く印刷しておく。つまり、印刷精度をやや緩和したものでよい。その上から黒い印刷である背景印刷部分１０ｅを印刷することにより、第１印刷部分１０ｂと第２印刷部分１０ｃの外周縁位置が決まるようにする。
さらに、第１印刷部分１０ｂや第２印刷部分１０ｃを設けた前面と反対側の後面には、拡散印刷部１０ａを設ける。拡散印刷部１０ａは、入光を拡散して出光させるものである。
この第１印刷部分１０ｂ等と反対側の後面の拡散印刷部１０ａ上に、調光印刷部１０ｆを設ける。調光印刷部１０ｆを設ける位置は、重なり部分１０ｄの印刷の無い前面部分と重なる位置である。
調光印刷部１０ｆは、波長に対する透過効率の特性として、図６に示す特性を有することによって、輝度と色みの両方において、調光を行う。
The first print portion 10b and the second print portion 10c are printed slightly wider than the first display 12 and the second display 13 that are actually displayed. That is, the printing accuracy may be slightly relaxed. The background printing portion 10e, which is black printing, is printed from above, so that the outer peripheral edge positions of the first printing portion 10b and the second printing portion 10c are determined.
Further, a diffusion printing unit 10a is provided on the rear surface opposite to the front surface on which the first printing portion 10b and the second printing portion 10c are provided. The diffusion printing unit 10a diffuses incident light to emit light.
A light control printing unit 10f is provided on the diffusion printing unit 10a on the rear surface opposite to the first printing portion 10b. The position where the light control printing unit 10f is provided is a position where it overlaps the front portion of the overlapping portion 10d where no printing is performed.
The light control printing unit 10f performs light control in both luminance and color by having the characteristics shown in FIG. 6 as the characteristics of the transmission efficiency with respect to the wavelength.
次に作用を説明する。
[表示作用]
(a)第１表示
実施例１において、第１表示１２を表示させるには、第１光源３を点灯させ、第２光源を消灯する。
第１光源３から発せられる光は、スライダ８の内側枠で、第１光源３の側方に発散する光を前方に反射する。
このスライダ８の内側枠の内部空間を通るようにして、前面部分からカラーフィルタ１０に光が入光する。
Next, the operation will be described.
[Display effect]
(a) First Display In Example 1, in order to display the first display 12, the first light source 3 is turned on and the second light source is turned off.
The light emitted from the first light source 3 reflects the light diverging to the side of the first light source 3 forward by the inner frame of the slider 8.
Light enters the color filter 10 from the front surface portion through the internal space of the inner frame of the slider 8.
カラーフィルタを構成する拡散印刷部１０ａの背面の一部には、調光印刷部１０ｆを設けているため、この部分において、輝度及び色みの調整がされて、光が拡散印刷部１０ａに入光することになる。
また、調光印刷部１０ｆ以外の部分では、輝度を損なうことなく拡散印刷部１０ａに入光する。
拡散印刷部１０ａでは、光が拡散され前面に向かうことになる。
この拡散により、第１印刷部分１０ｂ及び第２印刷部分１０ｃと、調光印刷部１０ｆの輝度及び色みの格差がなくなる。
Since a part of the back surface of the diffusion printing unit 10a constituting the color filter is provided with a light control printing unit 10f, brightness and color are adjusted in this part, and light enters the diffusion printing unit 10a. Will light up.
Further, in parts other than the light control printing unit 10f, the light enters the diffusion printing unit 10a without impairing the luminance.
In the diffusion printing unit 10a, the light is diffused toward the front surface.
Due to this diffusion, the difference in luminance and color between the first printed portion 10b and the second printed portion 10c and the dimming printing portion 10f is eliminated.
シート１０ｇの前面における、第１印刷部分１０ｂでは、図６に示すように第１光源３の光を通過させる（線２１と線２２で示す関係）ため、第１印刷部分１０ｂが明るく表示する。
この表示は、拡散印刷部１０ａにより光が拡散するため、光源の位置に重なる部分の輝度が最も高くなりすぎることなく、均一した表示になる。
In the first printed portion 10b on the front surface of the sheet 10g, the light from the first light source 3 is allowed to pass as shown in FIG. 6 (the relationship indicated by the lines 21 and 22), so the first printed portion 10b is displayed brightly.
Since the light is diffused by the diffusion printing unit 10a, the display is uniform without the luminance of the portion overlapping the position of the light source being excessively high.
さらに、重なり部分１０ｄ、つまり調光印刷部１０ｆでは、図６の波長に対する透過効率の関係において、第１光源３の光（線２２）で示される特定波長域の透過特性が、第１印刷部分１０ｂ（線２１）と調光印刷部１０ｆ（線２５）で近似している。
この図６の線２１と線２５における近似の状態において、透過効率が近似していることにより、輝度が第１印刷部分１０ｂと調光印刷部１０ｆで近似し、特定波長域が近似していることにより、色みが第１印刷部分１０ｂと調光印刷部１０ｆで近似する。
Furthermore, in the overlapping portion 10d, that is, the dimming printing unit 10f, the transmission characteristics in the specific wavelength region indicated by the light (line 22) of the first light source 3 in the relationship of the transmission efficiency with respect to the wavelength in FIG. 10b (line 21) and the light control printing unit 10f (line 25) are approximated.
In the approximate states of the line 21 and the line 25 in FIG. 6, the transmission efficiency is approximated, so that the luminance is approximated by the first printing portion 10b and the light control printing unit 10f, and the specific wavelength range is approximated. Thus, the color tone is approximated between the first printing portion 10b and the light control printing portion 10f.
一方、第２印刷部分１０ｃは、図６において、第１光源３の特性（線２２）に対して線２３で示す特性になるため、第１光源３の光は通過できない。
また、背景印刷部分１０ｅは、第１光源３の光、第２光源４の光のいずれも通過させない。
これにより、第１表示１２、つまり図５(a)に示す「Ａ」が表示されることになる。
On the other hand, since the second printed portion 10c has the characteristics indicated by the line 23 with respect to the characteristics (line 22) of the first light source 3 in FIG. 6, the light of the first light source 3 cannot pass therethrough.
Further, the background printing portion 10e does not allow the light from the first light source 3 or the light from the second light source 4 to pass through.
As a result, the first display 12, that is, “A” shown in FIG. 5A is displayed.
(b)第２表示
実施例１において、第２表示１３を表示させるには、第２光源４を点灯させ、第１光源３を消灯する。
すると、第２印刷部分１０ｃと第２光源４との関係は、図６の線２３と線２４の関係となるため、第２印刷部分１０ｃが明るく表示される。
さらに、重なり部分１０ｄ、つまり調光印刷部１０ｆでは、図６の波長に対する透過効率の関係において、第２光源４の光（線２４）で示される特定波長域の透過特性が、第２印刷部分１０ｃ（線２３）と調光印刷部１０ｆで近似している。
(b) Second Display In Example 1, in order to display the second display 13, the second light source 4 is turned on and the first light source 3 is turned off.
Then, since the relationship between the second printed portion 10c and the second light source 4 is the relationship between the line 23 and the line 24 in FIG. 6, the second printed portion 10c is displayed brightly.
Furthermore, in the overlapping portion 10d, that is, the dimming printing unit 10f, the transmission characteristics in the specific wavelength region indicated by the light (line 24) of the second light source 4 in the relationship of the transmission efficiency with respect to the wavelength in FIG. 10c (line 23) and the light control printing unit 10f are approximated.
この図６の線２３と線２５における近似の状態において、透過効率が近似していることにより、輝度が第２印刷部分１０ｃと調光印刷部１０ｆで近似し、特定波長が近似していることにより、色みが第２印刷部分１０ｃと重なり部分１０ｆで近似する。
一方、第１印刷部分１０ｂと第２光源４との関係は、図６において、線２１と線２４の関係となるため、第２光源４の光は通過できない。
また、背景印刷部分１０ｅは第１光源３及び第２光源の光をいずれも通過させない。
これにより、第２表示１３つまり、図５(b)に示す「Ｅ」が表示されることになる。
In the approximate states of the line 23 and the line 25 in FIG. 6, the transmission efficiency is approximated, so that the luminance is approximated by the second printing portion 10c and the light control printing unit 10f, and the specific wavelength is approximated. Thus, the color tone approximates the second printed portion 10c and the overlapping portion 10f.
On the other hand, since the relationship between the first printed portion 10b and the second light source 4 is the relationship between the line 21 and the line 24 in FIG. 6, the light from the second light source 4 cannot pass therethrough.
In addition, the background printing portion 10e does not pass the light of the first light source 3 and the second light source.
As a result, the second display 13, that is, “E” shown in FIG. 5B is displayed.
[スイッチ作用]
実施例１では、操作する人がスモークレンズ１１を押すと、一体化したスライダ８が摺動し、スライダ８の一部がタクトスイッチ５を押す。
スイッチ１としては、基板６に設けられる図示しない回路によって、どちらの表示状態において、タクトスイッチ５に入力があったかを判断し、２つの操作入力として使用する。これにより、１つのスイッチにおいて、異なるモードでの操作入力が可能となる。
[Switch action]
In the first embodiment, when the operator pushes the smoke lens 11, the integrated slider 8 slides and a part of the slider 8 pushes the tact switch 5.
As the switch 1, a display circuit (not shown) provided on the substrate 6 determines in which display state an input is made to the tact switch 5, and is used as two operation inputs. Thereby, operation input in different modes can be performed with one switch.
[コスト抑制作用及び光漏れ防止作用]
実施例１では、印刷を設けない重なり部分１０ｄを前面に設け、調光印刷部分１０ｆを後面に設ける。
そのため、前面における印刷精度の緩和となり、また、光漏れが防止される。
また、第１表示１２、第２表示１３は、黒色の背景印刷部分１０ｅにより所定の寸法形状で意匠部分を抜くポジ印刷ができるため、高精度の印刷を行うことなく精度のよい表示が行える。
また、印刷位置ズレによる光漏れは生じない。
さらに、調光印刷部分１０ｆは、重なり部分１０ｄより面積を広くしているので、精度を必要とせずに設けることができ、コストが抑制される。
[Cost control and light leakage prevention]
In the first embodiment, the overlapping portion 10d where printing is not provided is provided on the front surface, and the light control printing portion 10f is provided on the rear surface.
For this reason, the printing accuracy on the front surface is reduced, and light leakage is prevented.
Further, the first display 12 and the second display 13 can perform positive printing in which the design portion is extracted with a predetermined size and shape by the black background printing portion 10e, so that accurate display can be performed without performing high-precision printing.
In addition, light leakage due to printing position misalignment does not occur.
Furthermore, since the area of the light control printing portion 10f is larger than that of the overlapping portion 10d, the light control printing portion 10f can be provided without requiring accuracy, and the cost is suppressed.
[表示品質の向上作用]
(a)重なり部分１０ｄに印刷を施さない作用
重なり部分には、印刷を設けないため、印刷部分と印刷部分との印刷ずれが生じることがないため、表示品質が向上する。
[Improvement of display quality]
(a) Action of not printing the overlapping portion 10d Since the overlapping portion is not provided with printing, a printing shift between the printed portion and the printed portion does not occur, so that the display quality is improved.
(b)スライダの集光作用
スライダ８の枠状部分は、光源の側方への光を集めて前方に向かわせる。よって、全体的により明るい表示にすることができ、表示品質が向上する。
(b) Condensing action of the slider The frame-like portion of the slider 8 collects light toward the side of the light source and directs it forward. Therefore, overall brighter display can be achieved and display quality is improved.
(c)調光印刷部における調光作用
実施例１では、調光印刷部１０ｆにより、輝度と色みの調整が行われる。まず、輝度が調整されると、第１表示１２及び第２表示１３において、調光印刷部１０ｆとの差が目立たなくなり、その光の形状と色から第１表示１２、第２表示１３が認識される。輝度が調整されることにより、調光印刷部１０ｆを特に目立たなくし、良好に表示が認識される。
この輝度による作用は、調光印刷部１０ｆの形状を光で認識させながらも、目立たせないようにする。目立つと第１印刷部分１０ｂ又は第２印刷部分１０ｃと、調光印刷部１０ｆの差が目立つからである。
(c) Dimming Function in Light Control Printing Unit In the first embodiment, the brightness and color are adjusted by the light control printing unit 10f. First, when the brightness is adjusted, the difference between the first display 12 and the second display 13 and the light control printing unit 10f becomes inconspicuous, and the first display 12 and the second display 13 are recognized from the shape and color of the light. Is done. By adjusting the luminance, the light control printing unit 10f is not particularly noticeable, and the display is recognized well.
The effect of the brightness is made inconspicuous while the shape of the light control printing unit 10f is recognized by light. This is because the difference between the first printed portion 10b or the second printed portion 10c and the light control printing unit 10f is noticeable.
輝度による作用に色みの調整作用が加わることによって、第１印刷部分１０ｂと第２印刷部分１０ｃとの色差が小さくなる。すると、光の形状による認識、色による認識が相まって、より表示がはっきりと認識されることになる。
例えば、輝度のみの調整の場合、第１光源３、第２光源４の色、第１印刷部分１０ｂの色、第２印刷部分１０ｃの色のバラツキが大きいと、色差により、ある部分が目立って表示が認識しにくくなり表示品質が低下してしまう。
色みが調整されることにより、それぞれの色差が目立たなくなり、ばらつきがあっても、表示が充分に認識される。よって、より、はっきりと、表示の文字や形状が認識されるよう表示品質が向上する。
By adding the color adjustment effect to the luminance effect, the color difference between the first print portion 10b and the second print portion 10c is reduced. Then, the recognition by the shape of the light and the recognition by the color are combined, and the display is recognized more clearly.
For example, in the case of adjusting only the brightness, if there is a large variation in the colors of the first light source 3 and the second light source 4, the color of the first print portion 10b, and the color of the second print portion 10c, a certain portion becomes conspicuous due to the color difference. The display is difficult to recognize and the display quality is degraded.
By adjusting the color, each color difference becomes inconspicuous, and even if there is a variation, the display is sufficiently recognized. Therefore, the display quality is improved so that the character and shape of the display can be recognized more clearly.
次に効果を説明する。実施例１の可変表示構造にあっては、下記に列挙する効果を得ることができる。 Next, the effect will be described. In the variable display structure of the first embodiment, the effects listed below can be obtained.
(1)透光性のあるシート１０ｇに波長の異なる第１光源３の光と第２光源４の光を切り換えて投光させ、第１表示１２と第２表示１３を行わせる可変表示構造であって、シート１０ｇの片面に施された、第１光源３の波長のみを透過させる第１印刷部分１０ｂと、シート１０ｇの第１印刷部分１０ｂを設けた面に施された、第２光源４の波長のみを透過させる第２印刷部分１０ｃと、シート１０ｇの第１印刷部分１０ｂを設けた面に施された、第１光源３の波長と第２光源４の波長を透過させない背景印刷部分１０ｅと、第１表示１２と第２表示１３の重複する部分と重なる部分で、第１光源３及び第２光源４の光を抑制して輝度及び色度を調整する調光印刷部１０ｆを備えるため、高品質な２種類の表示ができる。
(2)調光印刷部１０ｆは、第１表示１２と第２表示１３の重複する部分より面積を大きくして、シート１０ｇの第１印刷部分１０ｂを設けた面と反対側の面に施されたため、第１印刷部分１０ｂを設けた面における印刷精度の緩和となり、また、光漏れが防止される。さらに、調光印刷部分１０ｆは、重なり部分１０ｄより面積を広くしているので、精度を必要とせずに設けることができ、コストが抑制される。
(1) A variable display structure in which the light of the first light source 3 and the light of the second light source 4 having different wavelengths are switched and projected on the translucent sheet 10g to perform the first display 12 and the second display 13. The second light source 4 is applied to one side of the sheet 10g, which is provided on the surface of the sheet 10g where the first printed portion 10b that transmits only the wavelength of the first light source 3 and the first printed portion 10b of the sheet 10g is provided. The second printed portion 10c that transmits only the first wavelength and the background printed portion 10e that is applied to the surface of the sheet 10g on which the first printed portion 10b is provided and does not transmit the wavelength of the first light source 3 and the wavelength of the second light source 4. And a dimming printing unit 10f that adjusts brightness and chromaticity by suppressing light from the first light source 3 and the second light source 4 in a portion that overlaps the overlapping portion of the first display 12 and the second display 13. High-quality two types of display can be performed.
(2) The light control printing unit 10f is applied to the surface of the sheet 10g opposite to the surface on which the first printing portion 10b is provided, with an area larger than the overlapping portion of the first display 12 and the second display 13. Therefore, the printing accuracy on the surface provided with the first printing portion 10b is eased, and light leakage is prevented. Furthermore, since the area of the light control printing portion 10f is larger than that of the overlapping portion 10d, the light control printing portion 10f can be provided without requiring accuracy, and the cost is suppressed.
(3)調光印刷部１０ｆは、第１光源３が点灯した際に、第１印刷部分１０ｂを通過した光と、調光印刷部１０ｆを通過した光の色みが同じになるよう調光印刷部１０ｆの色度を調整し、第２光源４が点灯した際に、第２印刷部分１０ｃを通過した光と、調光印刷部１０ｆを通過した光の色みが同じになるよう調光印刷部１０ｆの色度を調整したため、第１印刷部分１０ｂと調光印刷部１０ｆ、第２印刷部分１０ｃと調光印刷部１０ｆを通過する光の色差を小さくして、高品質な２種類の表示を行うことができる。 (3) The dimming printing unit 10f performs dimming so that when the first light source 3 is turned on, the color of the light that has passed through the first printing portion 10b and the color of the light that has passed through the dimming printing unit 10f are the same. When the chromaticity of the printing unit 10f is adjusted and the second light source 4 is turned on, the dimming is performed so that the light that has passed through the second printing portion 10c and the light that has passed through the dimming printing unit 10f have the same color. Since the chromaticity of the printing unit 10f is adjusted, the color difference of light passing through the first printing part 10b and the light control printing part 10f, the second printing part 10c and the light control printing part 10f is reduced, and two types of high quality Display can be made.
(4)調光印刷部１０ｆは、透過率の波長特性が、第１光源３の波長帯域においては、第１印刷部分１０ｂの透過率の波長特性と近似させ、第２光源４の波長帯域においては、第２印刷部分の透過率の波長特性と近似させたため、透過率特性の近似により輝度を調整し、波長特性の近似により色みを調整して、色みの調整により表示の色差を小さくし、輝度の調整でさらに調光印刷部１０ｆによる表示を目立たせないようにして、さらに高品質な２種類の表示を行うことができる。 (4) The dimming printing unit 10f approximates the wavelength characteristic of the transmittance in the wavelength band of the first light source 3 to the wavelength characteristic of the transmittance of the first printed portion 10b in the wavelength band of the second light source 4. Is approximated to the wavelength characteristic of the transmittance of the second printed portion, so the brightness is adjusted by approximating the transmittance characteristic, the color is adjusted by approximating the wavelength characteristic, and the color difference of the display is reduced by adjusting the color. In addition, it is possible to perform two types of higher-quality displays by making the display by the light control printing unit 10f inconspicuous by adjusting the luminance.
実施例２は、拡散シートを用いる例である。すなわち、実施例２では、シート１０ｇ、拡散印刷部１０ａを設けず、図７，図８に示すように拡散シート１０ｈを設ける。拡散シート１０ｈは、半透明であり、これにより光を拡散させて通過させるものである。このように拡散シートを用いてもよい。

FIG. 9 is an explanatory diagram showing a first display in the third embodiment. 10 is a cross-sectional view taken along line BB in FIG.
In the third embodiment, the dimming print portion 10f is provided on the front surface of the sheet 10g, that is, the surface on which the first print portion 10b and the second print portion 10c are provided, without providing the overlapping portion 10d.
Furthermore, as shown in FIG. 10, the first printing portion 10b is provided with a gradation portion 31 that reduces the amount of ink for printing as the distance from the first light source 3 increases, and the second printing portion 10c has a second printing portion 10c. A gradation portion 32 is provided that reduces the amount of printing ink as the distance from the second light source 4 increases.
シート１０ｇ後面に設けた拡散印刷部１０ａには、第１光源３からの距離が遠くなるにつれて、印刷のインキの量を少なくするグラデーション部３３と、第２光源４からの距離が遠くなるにつれて、印刷のインキの量を少なくするグラデーション部３４とを設ける。
その他構成は、実施例１と同様であるので説明を省略する。

A gradation portion 34 for reducing the amount of printing ink is provided.
Since other configurations are the same as those of the first embodiment, description thereof is omitted.
次に作用を説明する。
[輝度ムラについて]
図１３は第１光源３、第２光源４を点灯させた状態を示す説明図である。図１４は図１３のＣ−Ｃ断面図である。
第１光源３又は第２光源４を点灯させた場合において、その光を通過させて表示を行う場合に、第１印刷部分１０ｂ、第２印刷部分１０ｃ、調光印刷部１０ｆは、拡散印刷部１０ａ（又は拡散シート１０ｈ）で拡散処理が行なわれるが、第１光源３または、第２光源４に近い位置のほうが、輝度が高くなる輝度ムラを生じてしまう。
Next, the operation will be described.
[About uneven brightness]
FIG. 13 is an explanatory diagram showing a state in which the first light source 3 and the second light source 4 are turned on. 14 is a cross-sectional view taken along the line CC of FIG.
When the first light source 3 or the second light source 4 is turned on and the display is performed by passing the light, the first print portion 10b, the second print portion 10c, and the dimming print portion 10f are the diffusion print portion. Although the diffusion process is performed with 10a (or the diffusion sheet 10h), the unevenness of brightness in which the brightness is higher occurs at the position closer to the first light source 3 or the second light source 4.
輝度ムラが大きい場合には、調光の効果が失われることになり、調光印刷部１０ｆと第１印刷部分１０ｂ又は第２印刷部分１０ｃの違いが顕著に認識されてしまうことになる。このような場合には、表示品質が低下してしまうことになる。
これに対し本実施例３では、グラデーション部３１，３２，３３，３４を設けて、課題を解決している。
When the luminance unevenness is large, the dimming effect is lost, and the difference between the dimming printing unit 10f and the first printing portion 10b or the second printing portion 10c is remarkably recognized. In such a case, the display quality is degraded.
On the other hand, in the third embodiment, gradation portions 31, 32, 33, and 34 are provided to solve the problem.
[表示品質の向上作用]
実施例３においては、第１印刷部分１０ｂと第２印刷部分１０ｃにインキの量を段階的に変化させたグラデーション部３１，３２を設けている。もちろん、このグラデーション部は、調光印刷部１０ｆに設けてもよく、段階的な変化は、本実施例３のように無段階なものでも、ステップ的に段階的なものであってもよい。
このグラデーション部３１，３２においては、インキの量の違いにより、通過できる光の量が抑制されるため、輝度が調整される。そのため、第１光源３又は第２光源４の光源に対する距離による輝度の差が調整される。よって、第１表示１２又は第２表示１３において、輝度ムラがなくなり、第１印刷部分１０ｂ，第２印刷部分１０ｃと調光印刷部１０ｆを一体の表示として認識させることをより確実にし、表示品質を向上させる。
[Improvement of display quality]
In the third embodiment, gradation portions 31 and 32 in which the amount of ink is changed stepwise are provided in the first print portion 10b and the second print portion 10c. Of course, this gradation portion may be provided in the light control printing portion 10f, and the stepwise change may be stepless as in the third embodiment or stepwise stepwise.
In the gradation portions 31 and 32, the amount of light that can be passed is suppressed due to the difference in the amount of ink, so that the luminance is adjusted. Therefore, the difference in luminance depending on the distance of the first light source 3 or the second light source 4 to the light source is adjusted. Therefore, in the first display 12 or the second display 13, luminance unevenness is eliminated, and the first printing portion 10 b, the second printing portion 10 c, and the dimming printing unit 10 f are more reliably recognized as an integral display, and display quality is improved. To improve.
また、実施例３においては、拡散印刷部１０ａにおいても、グラデーション部３３，３４を設けている。光源に近づくにつれてインキ量を多くすることにより、光源に近い位置では、通過する光の量が強く制限されるとともに、より拡散が進むことになる。よって、さらに、輝度ムラがなくなるとともに、光源の位置での光が表示に見えてしまうようなことがなくなる。
よって、さらに表示品質が向上する。
In the third embodiment, gradation portions 33 and 34 are also provided in the diffusion printing portion 10a. By increasing the amount of ink as it approaches the light source, the amount of light passing therethrough is strongly limited at a position close to the light source, and diffusion further proceeds. Therefore, luminance unevenness is further eliminated and light at the position of the light source does not appear to be displayed.
Therefore, the display quality is further improved.

(5)透過性のあるシート１０ｇに波長の異なる第１光源３の光と第２光源４の光を切り換えて投光させ、第１表示１２と第２表示１３を行なわせる可変表示構造であって、シート１０ｇの片面に施された、第１光源３の波長のみを透過させる第１印刷部分１０ｂと、シート１０ｇの第１印刷部分１０ｂを設けた面に施された、第２光源４の波長のみを透過させる第２印刷部分１０ｃと、シート１０ｇに施された、第１光源３の波長と第２光源４の波長を透過させない背景印刷部分１０ｅと、シート１０ｇに施された、第１表示１２と第２表示１３の重複する部分と重なる部分で、第１光源３及び第２光源４の光を抑制する調光印刷部分１０ｆとを備え、第１印刷部分１０ｂ、第２印刷部分１０ｃに、インキの量を段階的に変化させたグラデーション部を設けたため、輝度ムラをなくし、表示品質を向上させることができる。

Of the second light source 4 applied to the surface of the sheet 10g provided with the first printed portion 10b that transmits only the wavelength of the first light source 3 and the first printed portion 10b of the sheet 10g. A second printed portion 10c that transmits only the wavelength, a background printed portion 10e that is applied to the sheet 10g and that does not transmit the wavelength of the first light source 3 and the wavelength of the second light source 4, and the first printed portion that is applied to the sheet 10g. A portion that overlaps the overlapping portion of the display 12 and the second display 13, and includes a dimming print portion 10 f that suppresses light from the first light source 3 and the second light source 4, and includes a first print portion 10 b and a second print portion 10 c. In addition, a gradation that gradually changes the amount of ink Due to the provision of the emission unit, eliminating luminance unevenness, thereby improving the display quality.
(6)背景印刷部分１０ｅと調光印刷部分１０ｆをシート１０ｇの第１印刷部分１０ｂに設けた面に施すようにし、シート１０ｇの第１印刷部分１０ｂを設けた面と反対側の面に、第１光源３及び第２光源４の光を拡散させる拡散印刷部１０ａを設け、拡散印刷部１０ａに、インキの量を段階的に変化させたグラデーション部２３，２４を設けたため、光源に近い位置の光の通過の制限と拡散を進め、光源の位置での光が表示に見えないようにでき、さらに表示品質を向上させることができる。
その他作用、効果は実施例１と同様であるので説明を省略する。
(6) The background printing portion 10e and the dimming printing portion 10f are applied to the surface provided on the first printing portion 10b of the sheet 10g, and on the surface opposite to the surface provided with the first printing portion 10b of the sheet 10g, Since the diffusion printing unit 10a that diffuses the light of the first light source 3 and the second light source 4 is provided, and the gradation units 23 and 24 in which the amount of ink is changed in stages are provided in the diffusion printing unit 10a, the position close to the light source The light can be restricted and diffused so that the light at the position of the light source cannot be seen in the display, and the display quality can be further improved.
Since other operations and effects are the same as those of the first embodiment, description thereof is omitted.
実施例４は、インキの量の変化を、光源の光と同色系のインキの量の変化とした例である。
図１１は、実施例４における可変表示構造の説明図であり、図１２は、実施例４におけるインキの量の説明図である。
実施例４では、例えば、第１光源３が赤い発光を行い、第２光源４が青い発光を行なうとする。
図１１は、説明上、第１表示１２が赤い「Ｉ」の表示、第２表示１３が青い「Ｅ」の表示を行なうものとする。この状態で、調光印刷部１０ｆを、図１１(b)に示すように、赤い第１光源３の近くでは青系のインキ量を増やし、赤い第１光源３の遠くでは青系のインキ量を少なくする。青い第２光源４の近くでは赤系のインキ量を増やし、青い第２光源の遠くでは赤系のインキ量を少なくする。よって、実施例４では、調光印刷部１０ｆ全体がグラデーション部に相当する。なお、このグラデーション部に相当する部分は一部に設けるものであってもよい。
Example 4 is an example in which the change in the amount of ink is a change in the amount of ink of the same color as the light from the light source.
FIG. 11 is an explanatory diagram of the variable display structure in the fourth embodiment, and FIG. 12 is an explanatory diagram of the amount of ink in the fourth embodiment.
In Example 4, for example, it is assumed that the first light source 3 emits red light and the second light source 4 emits blue light.
In FIG. 11, for the sake of explanation, it is assumed that the first display 12 displays red “I” and the second display 13 displays blue “E”. In this state, as shown in FIG. 11B, the dimming printing unit 10f increases the blue ink amount near the red first light source 3, and the blue ink amount far from the red first light source 3. Reduce. The red ink amount is increased near the blue second light source 4, and the red ink amount is decreased near the blue second light source. Therefore, in Example 4, the entire light control printing unit 10f corresponds to a gradation unit. Note that a portion corresponding to the gradation portion may be provided in part.
作用を説明する。
[輝度ムラについて]
表示の輝度ムラについて、図１３を参照して説明する。図１３に示すように、変化のない印刷が行われ、第１光源３を赤い発光、第２光源４を青い発光とした場合、調光印刷部１０ｆでは、赤い発光と青い発光のいずれにおいても、光を通過させ、かつ、赤い発光の場合に赤色と一体の意匠「Ｉ」と認識させる色での光の透過を行い、青い発光の場合に青色と一体の意匠「Ｅ」と認識させる色での光の透過を行なう。
この調光印刷部１０ｆにおいても、輝度ムラが発生し、光源の近くが明るすぎ、光源から離れると暗くなる表示となる。この変化が大きい場合には、調光の効果が失われることになり、調光印刷部１０ｆと第１印刷部分１０ｂ又は第２印刷部分１０ｃの違い（色差）が顕著に認識されてしまうことになる。このような場合には、表示品質が低下してしまうことになる。
これに対し本実施例４では、調光印刷部１０ｆにおいて、赤系インキ量と青系インキ量を段階的に変化させることで課題を解決している。
The operation will be described.
[About uneven brightness]
The display luminance unevenness will be described with reference to FIG. As shown in FIG. 13, when printing is performed without change, and the first light source 3 is set to emit red light and the second light source 4 is set to emit blue light, the dimming printing unit 10f performs either red light emission or blue light emission. , A color that allows light to pass through and transmits light in a color that recognizes the design “I” integrated with red in the case of red light emission, and recognizes a design “E” that is integrated with blue in the case of blue light emission. Transmits light at.
Even in the light control printing unit 10f, luminance unevenness is generated, the display near the light source is too bright, and the display becomes dark when the light source is separated from the light source. When this change is large, the dimming effect is lost, and the difference (color difference) between the dimming printing portion 10f and the first printing portion 10b or the second printing portion 10c is remarkably recognized. Become. In such a case, the display quality is degraded.
On the other hand, in the fourth embodiment, the problem is solved by changing the red ink amount and the blue ink amount stepwise in the light control printing unit 10f.
[表示品質の向上作用]
本実施例４では、第１光源３が赤い発光を行なうと、まず、第１印刷部分１０ｂがこの赤い発光を通過させることで、赤い透過光を通過させる。言い換えれば、第１印刷部分１０ｂは赤い発光を行なう。調光印刷部１０ｆでは、赤い光に対して赤に近く、例えばピンクに近い色で発光するよう赤色光を透過させる。
この調光印刷部１０ｆは、赤色系のインキ量が第１光源３からの距離に対し、一定であるならば、光源から遠い位置が暗くなり、全体として赤い「Ｉ」の文字が「Ｉ」かどうかわかりにくくなり、又は認識できなくなる。
本実施例４では、赤色光を発する第１光源３からの距離が近くなるほど、青色系のインキ量が多くなるため、透光量が調整され、光源からの遠近に対しても、輝度が一定な調光印刷部１０ｆとなり、全体として赤い「Ｉ」であるとはっきり見て取れる。つまり認識性が向上する。
[Improvement of display quality]
In the fourth embodiment, when the first light source 3 emits red light, the first printed portion 10b first passes the red light, thereby allowing red transmitted light to pass. In other words, the first printed portion 10b emits red light. The light control printing unit 10f transmits red light so that red light is emitted in a color close to red, for example, close to pink.
If the red ink amount is constant with respect to the distance from the first light source 3, the light control printing unit 10f becomes darker at a position far from the light source, and the letter “I” as a whole becomes “I”. Whether it becomes difficult to understand or unrecognizable.
In the fourth embodiment, the closer the distance from the first light source 3 that emits red light, the greater the amount of blue-based ink. Therefore, the light transmission amount is adjusted, and the brightness is constant with respect to the distance from the light source. The dimming print section 10f becomes clear and can be clearly seen as a red “I” as a whole. That is, the recognizability is improved.
第２光源４が青い発光を行なう場合には、第２印刷部分１０ｃが青い光を通過させることで、青い発光を行なう。調光印刷部１０ｆでは、青い光に対しては、青に近く、例えば紫色に近い色で発光するよう青色光を透過させる。
この青色光の場合においても、青色光を発する第２光源４からの距離が近くなるほど、赤色系のインキ量が多くなるため、光源からの遠近に対しても、輝度が一定な調光印刷部１０ｆとなり、全体として青い「Ｅ」であるとはっきり認識できる。
When the second light source 4 emits blue light, the second printed portion 10c transmits blue light, thereby emitting blue light. In the light control printing unit 10f, blue light is transmitted so as to emit light with a color close to blue, for example, near purple, for blue light.
Even in the case of blue light, the closer the distance from the second light source 4 that emits blue light, the greater the amount of red-based ink. 10f, and it can be clearly recognized as blue “E” as a whole.
効果を説明する。実施例４の可変表示構造では、以下の効果を有する。
(7)調光印刷部分１０ｆをグラデーション部とし、赤色系のインキ量を、赤色光を発する第１光源３から距離が遠くなるにつれて徐々に多くするようにし、青色系のインキ量を、青色光を発する第２光源４から距離が遠くなるにつれて徐々に多くするようにしたため、距離による色度の差をなくし、表示品質を向上できる。また、言い換えれば高品質の２種類の表示を同じ部位で切り換えて行うことができる。
また、実施例４では、調整印刷部分１０ｆにおいて、青系、赤系のインキ量について、光源からの距離に応じて段階的に変化させたが、全体のインキ量を光源からの距離に応じて段階的に変化させるようにしてもよい。全体のインキ量を変化させた場合の効果を以下に示す。
(8)調光印刷部分１０ｆは、全体のインキ量を光源との距離に応じて段階的に変化させたため、容易に光源との距離に関する輝度の調整を行うことができる。
Explain the effect. The variable display structure according to the fourth embodiment has the following effects.
(7) The light control printing portion 10f is a gradation portion, and the amount of red ink is gradually increased as the distance from the first light source 3 that emits red light is increased. As the distance from the second light source 4 emitting light increases, the difference in chromaticity due to the distance is eliminated, and the display quality can be improved. In other words, two types of high-quality displays can be switched at the same site.
Further, in Example 4, the blue and red ink amounts in the adjusted printing portion 10f are changed stepwise according to the distance from the light source, but the total ink amount is changed according to the distance from the light source. You may make it change in steps. The effect of changing the total ink amount is shown below.
(8) Since the light control printing portion 10f changes the entire ink amount stepwise according to the distance to the light source, the brightness relating to the distance to the light source can be easily adjusted.
