[Prior Art] Conventional stereoscopic color image The device for obtaining
No. 4928, JP-A-58-184929, t# Kai-Sho 5
As described in publications such as JP-A No. 8-118292, JP-A-60-48691, and JP-A-60-265594, an optical shutter or a polarizing plate is used.
光シヤツターを用いる方式は、表示装置上に左眼用画像

用シャッターと右眼用シャッターを交互に開閉すること
で、立体画像を得ている。The method using an optical shutter alternately displays images for the left eye and images for the right eye on the display device, and in synchronization with the display, alternately opens and closes the left eye shutter and the right eye shutter, thereby creating a three-dimensional image. I am getting .
一方、偏光板を用いる方式は、左眼用画像と右眼用画像
をそれぞれ直交する偏光で表示し、左眼用と右眼用に対
応した偏光板を通して見ることで立体画像を得ている。On the other hand, in the method using polarizing plates, a left-eye image and a right-eye image are displayed with orthogonal polarized light, and a three-dimensional image is obtained by viewing through the polarizing plates corresponding to the left-eye and right-eye images.
上記従来の光シヤツタ一方式は、左眼用と右眼用画像を

イールド（１／６０秒）ごとに左眼用と右眼用画像信号
を交互に送るため、片眼に対するフィールド周波数がｓ
ｏＨｚ法なりフリッカが生じる。The above-mentioned conventional optical shutter system displays images for the left eye and right eye alternately in a time-sharing manner, so for one eye, the display period and non-display period are repeated alternately, causing flickering on the screen. There are problems that can easily occur. Special K, current television system (NT
In the signal format of 3D television using the SC system, left-eye and right-eye image signals are sent alternately every field (1/60 second), so the field frequency for one eye is s.
Flicker occurs with the oHz method.

、正常な立体画像が得られない。On the other hand, the conventional polarizing plate method is capable of displaying images for the left eye and the right eye at the same time, and therefore has an advantage over the upper H-polar shutter method in terms of flicker. However, since polarized light is used, it is necessary to maintain the polarization direction of the polarized light emitted from the display device and the polarization direction of the polarizing plate of the glasses parallel or perpendicular, and if the direction of rotation of the glasses is tilted, the normal There is a problem with not being able to obtain 3D images. 1. The following problems arise when applying the polarizing plate method to ordinary cathode ray tubes. It is very difficult to align the polarizing filter and raster. The light from the phosphor must pass only through a predetermined polarizing filter, and because the faceplate is thick, a normal stereoscopic image cannot be obtained by simply placing a polarizing filter outside the faceplate.
本発明の目的は、フリッカのない高品質な立体画像が得
られる立体カラー画像表示装置を提供することにある。An object of the present invention is to provide a stereoscopic color image display device that can provide high-quality stereoscopic images without flicker.
〔課題を解決するだめの手段〕
上記目的は、左眼用と右眼用画像を形成する３原色の分
光スペクトルが異なるようにし、カラーフィルタめがね
で左眼用と右眼用の画像を分離する構成とすることによ
り達成される。[Failure to solve the problem] The above purpose is to make the spectral spectra of the three primary colors that form the left-eye and right-eye images different, and to separate the left-eye and right-eye images using color filter glasses. This is achieved by configuring the structure.
上記した構成においては、左眼用と右眼用画像を同時に
表示できるので、７９ツカは生じない。In the above-described configuration, the left-eye and right-eye images can be displayed simultaneously, so 79 images do not occur.
さらに、カラーフィルタめがねを使用するのでめがねに
方向性がなく、多少めがねが傾いても正常な立体画像が
得られる。Furthermore, since color filter glasses are used, the glasses have no directionality, and even if the glasses are slightly tilted, a normal stereoscopic image can be obtained.
また、陰極線管の螢光体の種類を適当に選択することで
、本発明を陰極線管に容易に適用できる。Furthermore, the present invention can be easily applied to cathode ray tubes by appropriately selecting the type of phosphor in the cathode ray tube.
以下、本発明の一冥施例を図面を用いて説明する。第１

光特性１０．１１を持っている。Reference numeral 1 indicates an image display device such as a cathode ray tube, liquid crystal panel, plasma display panel, or fluorescent display tube, and reference numeral 2 indicates color filter glasses. The screen of the image display device 1 is composed of pixels 3 forming an image for the left eye and pixels 4 forming an image for the right eye. In FIG. 1, left-eye pixels 3 and right-eye pixels 4 are alternately arranged in horizontal stripes. The operation of this pixel arrangement is the same whether it is in the form of vertical stripes or diagonal stripes, but the horizontal stripe arrangement is easier to drive. 9 (solid line) is the spectral spectrum of 50 pixels and 40 images for the right eye. On the other hand, the color filter glasses 2 are composed of a left eye color filter 5 and a right eye color filter 6 corresponding to the left eye and right eye, respectively. The color filters 5.6 for left eye and right eye are for left eye and
It has a spectral characteristic 10.11 that matches the spectral characteristic 8.9 of the right eye pixel 5.4.

を同時に表示でき、７リツカを防止することができる。In a general color image display device, the three primary colors of light (red, green, and blue CB) are used, and the mixing ratio is changed to produce various colors to obtain a color image. It is well known that there are. In the present invention, as shown in spectral characteristic 7, three
The peak wavelengths of the primary colors are shifted. As a result, even if the left eye pixel 5 and the right eye pixel 4 are illuminated at the same time, by using the color filters 5 and 6 corresponding to their respective spectral characteristics, the right eye pixel 5 can be used only for the left eye, and the right eye pixel 5 can be used only for the left eye. Pixel 4 is visible only to the right eye. Therefore, the image for the left eye and the image for the right eye can be displayed at the same time, and it is possible to prevent the image from appearing.

置１に対して傾いても正常な立体画像が得られる。Furthermore, since the color filters 5.6 do not have directionality like polarizing plates, a normal stereoscopic image can be obtained even if the color filter glasses 2 are tilted with respect to the image display device 1.

用い几ば間単に分光特性７を実現することができる。Next, a method of making the image display device 1 have the characteristics shown in the spectral characteristics 7 will be explained. First, in an image display device such as a color liquid crystal panel that uses color filters to achieve colorization, it is clear that a color filter having the characteristic M shown in spectral characteristic 7 may be used. In addition, in devices that use phosphors such as cathode ray tubes and plasma display panels, if two types of phosphors for each color are used, with the emission spectra of the R, G, and H phosphors slightly shifted, Spectral characteristic 7 can be realized, and in addition, efficiency is improved compared to the filter method. Note that even in a projection image display device using projection tubes, the spectral characteristic 7 can be easily achieved by using a total of six projection tubes for each of R, G, and B.
以下、画像表示装ｆ１として、陰極線管を用いた場合に

る。18 is a shadow mask, 19 is a fluorescent surface, and 20 is a face plate. Here, the difference from the well-known shadow mask type color cathode ray tube is that there are six electron guns in total, three for the left eye pixels and five for the right eye pixels. , left-eye and right-eye pixels 3 and 4, each of which has a fluorescent surface 19 composed of 2m type R, G, and B phosphors with shifted emission spectra.
It is formed by With such a configuration,
The left-eye and right-eye pixels 6 and 4 corresponding to each electron gun can be made to emit light at the same time, and flicker can be prevented.
次に、発光スペクトルのずれた２種類のＲ、Ｇ。Next, two types of R and G with shifted emission spectra.

る。Examples of B phosphors and the chromaticity range reproduced by these phosphors are shown in FIG. In the figure, the range of 21 triangles (dotted line) is the current TV system (NTSC system), the range of 22 triangles (actual) is the phosphor for the left eye, and the range of 26 triangles (dashed line) is for the right eye. Indicates the reproduction chromaticity range of the phosphor. In the figure, in order to make the color range of the left eye image and the right eye image the same, the color change of each image must be changed by 22 and 25. It is necessary to limit the area to the shaded area where the triangles overlap, but as you can see from the figure, it almost overlaps with the 21 triangles of the NTSC system, so the color reproduction range will be narrower than the current television receiver. There isn't. However, since the phosphors for the left eye and the right eye are different, if the same video signal is applied, the displayed colors will differ. Therefore, errors due to the difference in phosphors are corrected by a chromaticity correction circuit (described later).

In short, it is only necessary to determine the spectral characteristics 10.11 of the color filter glasses 20 corresponding to the image display device rIt and the 10 spectroscopic special 7, and the operation is exactly the same. 1 figure 10
．． 11 will be explained. It is difficult to obtain the characteristics shown in Figures 10 and 11 with a single color filter, so as shown in Figure 4, a single-spectrum transmission filter is used in a mosaic pattern (horizontal stripes) finer than the resolution of a doll's eye. If it is formed into a shape (or a vertical stripe shape),
Desired characteristics can be obtained. In Figure 4, 24
~26 and 27-29. are transmission filters having almost the same transmission spectrum characteristics as the emission spectra of the left-eye and right-eye phosphors, respectively. Alternatively, as shown in FIG. 5, if three single-spectrum absorption filters are stacked one on top of the other, desired characteristics can be obtained. In FIG. 5, 30 to 32 and 53 to 55 are for the right eye, respectively;
This is an absorption filter that has almost the same absorption spectrum characteristics as the emission spectrum of the phosphor for the left eye (note that the left and right sides are reversed from the above-mentioned transmission filter).

Write. Since the field memories 59 and 40 can be written and read at the same time, reading is performed while writing signals, and while signals are being written to the memory on the opposite side, the same data as before is being read again. As a result, as shown in FIG. 7(2), <5), a video signal is output from the field memory without interruption. The output signal from this memory is the aforementioned left eye #jt
