Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in so-called electrical display devices using electro-optic materials such as liquid crystals and elements utilizing electro-optic effects such as PLZT.

□Electrical display devices have been widely used in computer display boards, clock faces, etc.

However, this type of display device had a low decorative effect.

The present invention provides a three-dimensional display of displayed images in this type of display device to enhance the decorative effect and to make the display clearer.

The present invention will be explained in detail with reference to an example below.

As shown in FIG. 1, the lenticular screen 10 is formed by molding a vinyl chloride material into a continuous semi-cylindrical shape.

A three-dimensional pixel image A is projected by the electric display mechanism 20 almost at the focal point on the back surface of the lenticular screen 10.

The stereoscopic pixel image A is formed by arranging a plurality of images with left and right parallax in a stripe pattern.

As the electrical display mechanism 20, a liquid crystal display element, PLZT
Display elements utilizing electro-optic effects, electromic display elements, light emitting elements such as light emitting diodes, etc. can be used. In this embodiment, a transmissive liquid crystal display element is adopted as the electrical display mechanism 20, and the pixel Among the electrodes 22 and 22' displaying the image A, one electrode 22 is formed into pixels.

In the figure, 21 is a sealed liquid crystal, 2 is a display electrode, and 2E' is a display electrode.
23.23' is a glass substrate, 24.24' is a polarizing plate arranged so that the polarization directions thereof are perpendicular to each other, 25 is a diffuser plate, 2
6 is an illumination light source.

The images displayed by this electrical display mechanism 20 are characters, symbols, figures, etc., and for example, change images in which the displayed characters are changed by turning on and off the application of voltage to the electrodes 22, 22', such as digital character display. It is.

As described above, since the image displayed by the electric display mechanism 20 is pixelated, the lenticular screen 10
By looking through it, it appears to be floating or sinking from the display surface.

A transmission type two-dimensional image 30 is placed in a superimposed manner on the thus formed display surface.

In this embodiment, the two-dimensional image 30 is a reversal type photographic film, and the displayed image is a general image B that is not pixelated, such as a landscape.

The two-dimensional image 30 is preferably placed on the back or one surface of the lenticular screen 20 as shown in the figure.

In the display of the present invention, as shown in FIGS. 1 and 2, since the pixel image A formed by the electric display mechanism 20 is pixelized, it appears three-dimensionally when viewed through the lenticule screen 10. If it is a floating pixel image A, it will appear floating at the position of image A1.

Further, if the pixel image A is sunken, it appears sunken at the position of image A2.

On the other hand, the two-dimensional image 30 is visible at the position of the actual image B.

Since the present invention has the above configuration, it has the following effects.

Since the displayed image of the present invention is a three-dimensional image, the decorative effect is extremely high and the displayed image is extremely clear.

When performing a three-dimensional display, even if a three-dimensional image is displayed, the ups and downs will not be clearly visible unless the image is clearly visible at the reference position of the ups and downs.

In this invention, a two-dimensional image is superimposed on a three-dimensional image, and this image is clearly visible as an image of the reference position, so that the ups and downs of the image caused by the electric display mechanism become clear.

Therefore, the three-dimensional image display device of the present invention exhibits an excellent practical effect when used for a clock face or the like where a decorative effect is required.
