【0009】 [0009]

【実施例】以下、本発明の実施例を図面を参照しながら詳細に説明する。 EXAMPLES Hereinafter, an embodiment of the present invention in detail with reference to the drawings. 図1は、本発明にかかる表示装置を前面から見た場合の一部を示す外観図である。 Figure 1 is an external view showing a part of a case of viewing the display device according to the present invention from the front. 図1に示すように、この表示装置1は独立した円形状の素子2を多数縦横に配置された構成となっている。 As shown in FIG. 1, the display device 1 has a arranged a circular element 2 independent multiple aspect configuration. この素子2の1 1 of the element 2
つ1つが画素を構成することになるが、通常のCRTディスプレイと異なって1つの画素2から種々の色が光干渉現象によって出力されるようになっている。 One one but it constitutes the pixel, various colors from one pixel 2 is different from the conventional CRT display are outputted by optical interference phenomena.

【0010】この各画素2を構成する機構の一例は図2 [0010] One example of a mechanism constituting the respective pixels 2 2
に示してある。 It is shown in. 表示装置1の前面側には光干渉形成部材として機能するガラス3が取り付けられている。 The front side of the display device 1 glass 3 which functions as an optical interference form member is mounted. このガラス3の後面側には、透明の導電膜4が形成されている。 This rear side of the glass 3, the conductive film 4 of the transparent are formed. そして、このガラス3の後面側には、所定の寸法で形成されている圧電素子5の一方側を導電膜4に接触させ、かつ印加される電圧に応じてガラス面に対して前後方向に歪むような方向に取り付ける。 Then, the rear surface side of the glass 3, distorted in the longitudinal direction relative to the glass surface in accordance with the one side is brought into contact with the conductive film 4, and the voltage applied to the piezoelectric element 5 are formed in a predetermined dimension attached in a direction such that. そして、ガラス8 Then, glass 8
の一方の面には上記と同様の透明の導電膜7を形成し、 On one surface of a conductive film 7 similar to the above transparent,
これにたとえばシリコン等が表面に形成されている反射部材として機能する部材9を取り付ける。 This example silicon or the like attaches the member 9 which functions as a reflecting member formed on the surface. さらに、このガラス8の導電膜7形成側に圧電素子5の他端側を導電膜7を接触させるようにして取り付ける。 Furthermore, attaching the other end of the piezoelectric element 5 so as to contact the conductive film 7 on the conductive film 7 formed side of the glass 8. このときには、部材9が圧電素子5に接触しないようにする。 In this case, member 9 does not contact the piezoelectric element 5. 導電膜4はアースに接続し、導電膜7は画素毎にこの圧電素子5のそれぞれに対して独立して電圧を印加する後述の圧電素子群電圧制御部に接続する。 The conductive film 4 is connected to ground, the conductive film 7 is connected to the piezoelectric element group voltage control unit described later to apply a voltage independently for each of the piezoelectric element 5 for each pixel.

【0011】このような構成によって干渉色が発生するのは次のような理由による。 [0011] by as follows reason why the interference color produced by such a configuration. 鏡面仕上げが施されたシリコンとガラスとの間隙を非常に小さく設定(数百nmオーダー)した場合には、ガラスを介して入射した光とシリコンに反射した光とによって干渉が生じ、これによってガラスとシリコンとの間に干渉色が発生する。 If the mirror finish was very small set (several hundred nm order) the gap between the silicon and the glass has been subjected, interference occurs by the light reflected to the light and silicon incident through the glass, whereby the glass interference color is generated between the silicon and. つまり、この色の感じは、入射光と反射光との間で打ち消し合う干渉で消える部分を引いたもので作られることになる。 That is, the feeling of the color will be made minus the portion disappear destructive interference between the incident light and the reflected light.

【0012】図3は、本発明の表示装置を駆動させるための制御系の構成を示したブロック図である。 [0012] Figure 3 is a block diagram showing the configuration of a control system for driving the display device of the present invention. メモリ1 Memory 1
0には、表示装置1に静止画像を表示させる場合に使用される各画素ごとの画像情報及び画像をカラー化するための画像情報が記憶されている。 0, the image information for color of the image information and the image for each pixel to be used when displaying the still image on the display device 1 are stored. つまり、この画像情報はどの画素には何色を出させるかという情報であり、具体的には、表現すべき色に対応して各画素を構成する圧電素子に印加すべき電圧の情報である。 That is, the image information is information indicating to out what color to which the pixel, specifically, is the information of the voltage to be applied to a piezoelectric element constituting each pixel corresponding to the color to be expressed . 外部装置11 The external device 11
は、例えばテレビジョン用のチューナやVTR等であり、この外部装置11からはカラーの画像信号が出力される。 Is, for example, a like tuner or VTR for a television, an image signal of the color from the external device 11 is output. メモリ10に記憶されている画像情報に基づいて静止画像を表示する場合には、CPU12はこの画像情報とカラー化のための画像情報とに基づいてどの圧電素子にどの程度の電圧を印加すべきかを演算し、一方、動画像を表示する場合には、外部装置11から出力されたカラーの画像信号に基づいてメモリ10に記憶されているカラー化の情報を参照し、どの圧電素子にどの程度の電圧を印加すべきかを演算するものである。 Or when displaying a still image based on the image information stored in the memory 10, CPU 12 is to be applied the degree of the voltage to which the piezoelectric element based on the image information for the image information and the color of calculated, whereas, in the case of displaying a moving image, the information in the colorization stored in the memory 10 based on the color image signal output from the external device 11, how much to which the piezoelectric element it is intended for calculating whether to apply a voltage. 圧電素子群電圧制御部13は、CPU12の演算結果に基づいて圧電素子群5を構成する各圧電素子に電圧を印加する。 The piezoelectric element group voltage control unit 13 applies a voltage to the piezoelectric elements constituting the piezoelectric element group 5 according to the result of the CPU 12.

【0013】以上のように構成された本発明にかかる表示装置は、次のようにしてカラー表示を行なうことになる。 [0013] The above display device according to the present invention configured as described above, so that a color display in the following manner. まず、外部装置11からカラー画像に関する信号がCPU12に入力されたとすると、CPU12はこのカラー信号に基づいて、各圧電素子5に印加すべき電圧をメモリ10に記憶されている情報から演算する。 First, when the signal relating to color image from the external device 11 is input to the CPU 12, CPU 12, based on this color signal, it calculates a voltage to be applied to the piezoelectric element 5 from the information stored in the memory 10. 例えば、図2において、3つのそれぞれの画素A,B,Cについて、Aについては赤が、Bについては緑が、そしてCについては金属色がそれぞれ表示すべき信号が入力されたとし、メモリ10に記憶されている情報において、 For example, in FIG. 2, three of each pixel A, B, the C, red for A is, green for B is and a metallic color has been input signal to be displayed respectively for the C, the memory 10 in the information stored in,
赤を表示する場合には1.0Vが、緑を表現する場合には0.8Vが、また金属色を表現する場合には0Vがそれぞれそれぞれ割り当てられていたとすると、CPU1 When the 1.0V to display the red is, 0.8V in the case of representing the green, also in the case of expressing the metal color is set to 0V is allocated each, respectively, CPU1
2は、入力した画像信号に基づいてメモリの内容を参酌しながら、どの圧電素子には何Vの電圧を印加すべきかを演算する。 2, based on the image signal input with reference to the contents of the memory, the which the piezoelectric element calculates whether to apply a voltage of several V. この演算結果は圧電素子群電圧制御部13 The calculation result is the piezoelectric element group voltage control unit 13
に出力されることになる。 It will be output to. 圧電素子群電圧制御部13では、この入力した演算結果に基づいて、各圧電素子にこの電圧を印加する。 In the piezoelectric element group voltage control unit 13, on the basis of the inputted calculation result, and applies the voltage to the piezoelectric elements.

【0014】この電圧が印加されると、圧電素子はその印加電圧に応じてガラス面方向に伸縮することになる。 [0014] When this voltage is applied, the piezoelectric element is to stretch the glass surface direction in accordance with the applied voltage.
本実施例では印加電圧が大きくなるほど圧電素子の縮み量が大きくなるようになっている。 In the present embodiment so that the contraction amount of the piezoelectric element as the applied voltage increases increases. したがって、1.0 Therefore, 1.0
Vの電圧が印加される画素Aにおいては、圧電素子5の変型割合が3つの画素を構成する圧電素子の中で最も大きくなり、シリコン面とガラス面との間隙がこの3つの画素の中では一番大きくなる。 In the pixel A of voltage V is applied, becomes maximum in the piezoelectric element variation rate of the piezoelectric element 5 constitutes three pixels, the gap between the silicon surface and the glass surface in the three pixels most increases. この電圧におけるシリコン面とガラス面との間隙は、予め設計段階で外部からあたかもシリコン面が赤く発光していると見えるように設定されている。 The gap between the silicon surface and the glass surface at this voltage is set to appear as though the silicon surface from the outside is emitting light red with pre-design phase. 同様に、画素Bを構成する圧電素子の変型も0.8Vの印加電圧に相当する量だけとなって、シリコン面とガラス面との間隙は、画素を外部からある角度をもって見ている人には緑に発光しているように見える距離に設定される。 Similarly, becomes only the amount corresponding to variation even 0.8V applied voltage of the piezoelectric element constituting the pixel B, the gap between the silicon surface and the glass surface, the people watching at an angle to the pixel from outside It is set to a distance that appears to have been a light-emitting in the green. さらに、画素Cについては電圧が印加されないので、シリコン面はガラス面に接触状態のままとなっていて、金属色(シリコンそのものの色)が外部からは見えることになる。 Further, since the voltage for the pixel C is not applied, the silicon surface is remains as the contact with the glass surface, metallic color (color of the silicon itself) will be visible from outside.

【0015】尚、各画素を構成するにあたって、シリコン面によって生成される色は非常にわずかなガラス面に対する平面誤差でも変化してしまうので、ガラス面とシリコン面との平行度は非常に高精度で設定する必要がある。 [0015] Incidentally, when constituting each pixel, the color produced by the silicon surface varies in the plane error for very small glass surface, parallelism between the glass surface and the silicon surface is very accurate in it it is necessary to set. また、大画面になるにしたがってこれらの画素を構成する部材を支える枠組みの強度を保つ必要がある。 Further, it is necessary to maintain the strength of the framework supporting the members constituting these pixels in accordance becomes large screen. このように本発明の表示装置においては、シリコン面とガラス面との間隙及び自然光によって生じる干渉色を利用して画像を生成するものであるから、その表示に要する電力は従来の大画面のものに比較して格段に少なくなる。 Thus, in the display device of the present invention, since by using the interference color caused by gaps and natural light between the silicon surface and the glass surface to generate image, power required for the display of conventional large-screen It becomes much less compared to. また、大画面を構成するにあたっては、この画素を構成する部材の数を増加させ、この画素を構成する圧電素子への印加電圧制御の数を増加させるだけで良いので、画面サイズに容易に対応することができることになる。 Also, when constituting a large screen, by increasing the number of members constituting the pixel, since it only increases the number of voltage application control to the piezoelectric elements constituting the pixel, easily adapted to the screen size it will be can be. さらに、液晶ディスプレイでは困難とされている中間色も圧電素子への印加電圧を微妙に調整することで容易に制御することができるようになる。 Further, even intermediate color in the liquid crystal display is difficult so that it is possible to easily control by slightly adjusting the voltage applied to the piezoelectric element.

【0016】本発明の表示装置は、自然光によるシリコン面の反射を利用して画像を生成しているから、光のない夜間では表示を行なうことができない。 The display device of the present invention, because they generate an image using the reflection of the silicon surface by natural light, at night without light can not perform display. しかしながら、表示装置の側面側から照明すれば、表示色は照明の光の特性に応じて多少変化するものの、昼間とほぼ同様の画像が得られることになる。 However, if the lighting from the side of the display device, although the display color changes slightly depending on the characteristics of the illumination light, so that substantially the same image as the daytime can be obtained.

【0017】 [0017]

【発明の効果】以上説明したように本発明によれば、表示する色を反射部材と光干渉形成部材との間隔を調整することで表現するようにしているので、表示に要する電力は非常に少なくなる。 According to the present invention as described in the foregoing, since as expressed by adjusting the distance between the reflecting member and the light interference member color to be displayed, the power required for the display is very less. また大画面に対応させるには、 In addition to adapt to the big screen,
反射部材の数を増加させることで対応することができるから、画面サイズの要求に柔軟に対応することができるようになる。 Since it is possible to cope with increasing the number of reflecting members, it is possible to flexibly cope with the request of the screen size.
