STEREOSCOPIC DISPLAY APPARATUS HAVING SPACE BETWEEN THIN LENTICULAR LENS AND INTERLACED IMAGE}

The present invention relates to the production of a three-dimensional image using a thin lenticular lens, the conventional technique is to combine a transparent plate of glass and acrylic for securing the focal length of the lens to a thin lenticular lens on the flat surface of the transparent plate By producing the three-dimensional image by laminating the output image, not only the price but also the weight increases, so it is difficult to sell, transport, and install, but instead of using the transparent plate, a frame is applied to the edge to form a space apart. The present invention relates to a technology for manufacturing a stereoscopic display at a light and low cost.

A typical integrated lenticular lens is a transparent lens forming a thickness corresponding to a focal length (a distance between FIGS. 1 and 2) and a lens surface (5 in FIG. 2) consisting of a repetitive array of one-way convex lenses of horizontal or constant tilt. Produced in the form of a combination of regions (the spacing between 3 and 4 in FIG. 1), the smaller the LPI-Lines Per Inch, the greater the thickness of the lens, and this thicker lens has a very uniform cooling across the front of the lens after extrusion. The thin lenticular lens developed to solve the problem of the cooling process has been difficult to affect the quality of the lens only in the thin portion of the lens (5 in FIG. 2) except the transparent region (6 in FIG. 2). It is produced and distributed under the UltraLenz brand of MicroLens Corp., which also provides a uniform focal length of the lens suitable for the player (LPI) like the existing integrated lens. There is a limit to obtain a commercial three-dimensional quality only when used in combination with a certain thickness of transparent acrylic and glass plate for beams. In addition, the sharpness of the image is reduced by the influence of the transparent adhesive component used in the bonding process by the above-mentioned paper, and the stereoscopic image may be distorted due to the refraction of the transparent plate, which may cause the stereoscopic image to be dizzy.

 The present invention, in the manufacture of a three-dimensional display using a thin lenticular lens (in Fig. 2) and the output image (in Fig. 2) and instead of combining the transparent plate (6 in Fig. 2) As shown in FIG. 4, the thin film type lenticular lens 12 and the output image 14 are sandwiched between the frames 13 so as to replace the transparent region with a transparent space instead of a solid. And image to secure the separation space (9 in FIG. 3) to replace the transparent plate by applying the frame of the right, right and up, down bidirectional or left, right, top, bottom, or polygonal structure (11 in FIG. 3).

In order to implement the present invention, a commercially supplied thin film lenticular lens and an interlaced image output by mixing multiple angle images equal to the pitch of the lens are required. This part relates to general lenticular manufacturing. Since the contents are excluded from the description of the present invention.
The present invention provides a focal length that is a distance between the lens (20 of FIG. 6) and the output image (22 of FIG. 6) when manufacturing a stereoscopic display using a thin lenticular lens between the lens and the output image. Instead of the conventional method of using a transparent material such as glass or transparent acrylic having a thickness corresponding to the focal length, the image frame is provided with a frame or frame frame made of wood or resin material (frame 21 in Fig. 6) as the focal length thickness. .
The present invention is a method of making a three-dimensional display to secure the separation space corresponding to the focal length by using a frame instead of a heavy solid transparent material, having a lens on the side of the frame in the direction of the observer and the output image on the opposite side of the frame And the lens and the output image are stretched by pulling in the outward direction of the frame, and then a fixing pin composed of a stapler or a tacker for wood or resin is driven and fixed as shown in 18 of FIG. Creating a display is the basic way.
Hereinafter, a configuration for fixing the lens and the output image will be described.
Here, the lens and the output image may be crying or crumpled between the portion where the fixing pin is stuck and the portion that is not nailed, which may prevent securing a uniform space. In order to solve this problem, a fixing bar (19 in FIG. 6) is padded. The fixing pin (18 in FIG. 6) is configured to fix the lens and the output image in a more taut state. Accordingly, the flatness of the lens and the output image and the uniformity of the separation space generated between the two objects can be improved to create a three-dimensional display of higher quality. At this time, the fixing bar (19 of FIG. 6) has a narrower width than the frame width and the lens and output image using a material such as Formax or wood of a thickness that can be passed through the fixing pin (18 of FIG. 6) used. It can be configured with a length that fits each side of the edge.
Pulling the lens and the output image in the frame in the outward direction can be done by the operator's power, but a tensioning tool, which is a pulling mechanism, can be used to facilitate the work.
Hereinafter, a three-dimensional display in the form of a banner capable of displaying a variable size of a lens and an output image with reference to FIGS. 8 to 9 will be described.
By modifying the fixed three-dimensional display using the frame, which is the basic structure of the present invention described above, it is possible to make a three-dimensional display in the form of a banner (banner) that can replace the three-dimensional image, for which a three-dimensional banner holder is required.

The upper holders 29 and 30 consist of an upper front part 29 fixing an upper end of the lens 33 attached to the observer side and an upper rear part 30 fixing an upper end of the output image 34. The lower holders 31 and 32 consist of a lower front part 31 fixing the lower end of the lens 33 and a lower rear part 32 fixing the lower end of the output image 34.
The upper end of the lens 33 and the output image 34 are fixed to the upper front part 29 and the upper rear part 30 of the upper holders 29 and 30 so that the lens 33 and the output image 34 are separated from each other. The separation distance of) should be the lens focal length, and the distance 41 is determined according to the LPI of the lens. Also, the distance 41 is fixed to the lower front part 31 and the lower rear part 32 of the lower holders 31 and 32. The interval between the lens 33 and the output image 34 is also the same as the interval 41.
In other words, the pair of the first upper holder 29 and the first lower holder 31 for fixing the lens 33 on both sides of the upper and lower sides, It consists of a pair of the 2nd top holder 30 and the 2nd bottom holder 32 for fixing the image 34 in the upper and lower sides. The first upper holder 29 and the second upper holder 30 are spaced apart from each other by a focal length, and the first lower holder 31 and the second lower holder 32 are also disposed to secure the same separation space. .

The pair of upper bars 40a and 40b are provided in the upper front part 29 and the upper rear part 30 of the upper holders 29 and 30, respectively, so that they do not fall out through the respective insertion holes 29a and 30a. The upper end of the lens 33 and the output image 34 fixed to the pair of upper bars 40a and 40b are fixed to the upper holders 29 and 30.
Lower ends (not shown) of the same shape as the upper bars 40a and 40b may be fixed to the lower ends of the lens 33 and the output image 34, respectively.
The connecting parts a and b are installed to protrude from the centers of the rear surfaces of the upper holders 29 and 30 and the lower holders 31 and 32, respectively.
The upper and lower supports 35 and 36 are for fixing the upper holders 29 and 30 and the lower holders 31 and 32 up and down at the rear of the output image 34. The upper support 35 is an upper connection part. It is formed downward from (a), the lower support 36 is formed to extend from the upper connection portion (b) to the top.
Height adjustment device 37 is installed on the upper and lower support members 35 and 36. The height adjustment device 37 has a male groove of the screw dug in the opposite direction with respect to the position where the upper support 35 and the lower support 36 are engaged inside the device, and the upper and lower surfaces of the upper and lower supports 35 and 36 are inclined. It can also be configured to create a corresponding female groove of the screw. When the height adjustment cabinet 37 is rotated in the clockwise direction, the gap between the upper and lower supports 35 and 36 is opened, and the gap between the upper holders 29 and 30 and the lower holders 31 and 32 is opened so that the lens 33 ) And the height of the output image 34 is increased up and tightened, and when rotated counterclockwise, the gap is narrowed so that the height of the lens 33 and the output image 34 is lowered to be loosened.

On the other hand, the upper and lower supports 35 and 36 may be fixed to the upper and the connecting portions (a, b) respectively installed on the rear of the upper and lower holders (29, 30, 31, 32), but to facilitate transportation. In order to, as shown in FIG. 10, the upper and lower holders 35, the connecting male 45 and the lower supporting member 36 are provided with the connecting male 46, and the upper and lower holders 29, 30, 31, 32) can be fixed by plugging into the upper end 43 and the lower end 44 of the connecting female respectively attached to the center of the rear. Thus, the distance between the upper holders 29 and 30 and the lower holders 31 and 32, that is, the total length of the upper and lower supports 35 and 36 may be variable.

As the size of the image increases, the central part of the image may be stuck between the lens and the output image due to the property of the static electricity, which may cause the uniformity to be broken.In this case, the holder may be mounted not only on the upper and lower holders but also on the left and right sides. The problem can be solved by the additional pulling structure.
