第 1図は、 本発明の力ラーディスプレー装置を説明するため の図で、 マ ト リ ッ ク ス構造の 1画素を示している。  FIG. 1 is a view for explaining the force display device of the present invention, and shows one pixel having a matrix structure.

この例における発光体 l a、 l b、 一 m nは、 発光波長の異なる複 数個の発光ダイ オー ドである。 光の 3原色、 即ち赤、 黄緑、 青 を合成する こ とにより、 任意の色を作り出すこ とができる。 従 つて、 これら 3色の発光ダイ オー ドを集中して並べ、 各々の発 光強度を変える こ とによ り、 任意の色を合成できる。  The light emitters l a, l b, and 1 mn in this example are a plurality of light emitting diodes having different light emission wavelengths. Arbitrary colors can be created by combining the three primary colors of light, red, yellow-green, and blue. Therefore, by arranging these three light emitting diodes in a concentrated manner and changing the light emission intensity of each, an arbitrary color can be synthesized.
発光ダイ オー ドの場合、 発光スぺク トルの半値幅は数 l O n mと 狭く 、 3色では中間色の色捕正が十分に出来ない場合もある。 その場合には、 他に発光波長の異なる発光ダイ オー ドを追加し、 可視光の任意の色は、 これらの発光ダイ オー ドからの発光の合 成と して得る こ とができ る。  In the case of a light-emitting diode, the half-width of the light-emitting spectrum is as narrow as several l Onm, and there are cases where three colors cannot sufficiently correct the intermediate color. In that case, other light-emitting diodes having different emission wavelengths are added, and an arbitrary color of visible light can be obtained as a combination of light emitted from these light-emitting diodes.

Mn corresponds to one pixel in a color display device. As for the structure, a plurality of light emitting diodes may be molded at once, or separately molded ones may be concentrated. Since the light emitting diode element (chip) can be as small as about 300 μm x 300 μm or smaller, it is possible to mold multiple (for example, 3 or 5) devices at once. The image resolution of the color display device is not reduced.
第 2図（a ) は、 任意の可視光をし作る場合の所要の発光体に 対する時系列バルスのタ イ ムチャー トの一例を説明するための 図である。 図中横軸は時間 t 、 縦軸は光出力 Pであり、 R、 G、 B は赤、 黄緑、 青の信号である。 Tはパルスの周期で、 走査周 波数により決ま り、 パルス幅 t。は発光体の数 （全画素数） によ り決められる時間である。 発光体から出る光の色は、 赤 R、 黄 録 G、 青 Φ 流値 率で镧御する。，ち、 ^ ¾光;体 流す 電流値の比率を変えることによって色を作り出す。 例えば橙色 の場合には、 青 Bは点灯せず、 赤 Rと黄緑 Gにある比率で電流 を流して作る。 この比率は各発光体の効率、 人間の目の視感度 等により決められる。 FIG. 2 (a) is a diagram for explaining an example of a time-series pulse chart for a required luminous body when producing arbitrary visible light. In the figure, the horizontal axis is time t, the vertical axis is optical output P, and R, G and B are red, yellow-green and blue signals. T is the pulse period, which is determined by the scanning frequency, and the pulse width t. Depends on the number of illuminants (the total number of pixels) It is a time that can be decided. The color of light emitted from the illuminant is controlled by red R, yellow recording G, and blue Φ flow rate. , Chi, ^ ¾light; body flow Color is created by changing the ratio of the current value. For example, in the case of orange, blue B is not lit, and current is made to flow at a certain ratio between red R and yellow-green G. This ratio is determined by the efficiency of each light emitter, the visibility of the human eye, and the like.

又、 第 3図（b) のように、 軟質铯緣体基板 3 中に、 周期的に 薄い層を設ける こ とにより、 より曲がり易いものとなる。  Further, as shown in FIG. 3 (b), by providing a thin layer periodically in the soft magnetic substrate 3, it becomes easier to bend.
電源配線及び信号配線は、 各発光素子に結合し格子状に配線 されている。 配線網の簡略化及び、 配線ィ ンビーダンスの影響 による相互干渉の防止及び信号伝送の高速化の為には、 配線の 少な く とも片方を共通配線する こ とにより その効果を高める こ とができる。 カ ラ ーディ スプレー装置の用途により、 例えば色 別にま とめる こ とも出来る しあるいは列、 行ごとに共通配線に する こ とも出来る。  The power supply wiring and the signal wiring are connected to the respective light emitting elements and wired in a grid pattern. In order to simplify the wiring network, prevent mutual interference due to the influence of the wiring impedance, and increase the speed of signal transmission, the effect can be enhanced by wiring at least one of the wirings in common. Depending on the application of the color display device, for example, it can be grouped by color, or can be shared by columns and rows.
このように、 格子状に究光素子を複数個配列する ときには、 共通配線を二次元的に行なう こ とによ り、 簡素化および信号処 理の高速化等の利点が生ずる。  As described above, when a plurality of photodetectors are arranged in a grid, by arranging the common wiring two-dimensionally, advantages such as simplification and speeding up of signal processing are brought about.
