Description

Stereoscopic poster device that can exchange pictures {image changeable 3D steroscopic poster apparatus}

 The present invention relates to a three-dimensional poster device capable of viewing a three-dimensional image without a stereoscopic glasses in a poster posting device, such as a movie poster, and in particular, can be easily replaced the three-dimensional poster from time to time.

Movie advertisements are replaced from time to time, so posters promoting them should be replaced from time to time.

In addition, since posters are installed in many places, it must be easy to replace and can be made by anyone.

In particular, 3D movies are effective when they are promoted as 3D posters, but they are replaced by 2D posters because there is no suitable 3D poster device.

The 3D poster can be used as a 3D poster without stereoscopic glasses, but there is a structure like a stereoscopic card, but such a structure prints a stereoscopic image on the back of the lenticular plate.

 In the same manner as the three-dimensional card, the lens pitch spacing of the lenticular plate and the left and right picture intervals of the three-dimensional drawing must match, and the three-dimensional drawing should closely contact the back of the lenticular plate without being spaced apart so that the three-dimensional drawing on the lenticular plate itself. There was no other method than printing the left and right picture of.

However, the above method of printing or laminating onto the lenticular plate itself requires the waste of the lenticular itself only once and needs to be discarded.

Since it is not reusable and the lenticular itself is expensive, it is not possible to apply it to an advertising device that has a large picture, a large amount of installation like a movie poster, and frequently replaces a pro in many places.

In addition, U.S. Patent No. 7,210.257 discloses a structure in which a picture and a lenticular are brought into close contact with a vacuum by using a pump, but the device shows two pictures as the lenticular moves, and is not a stereoscopic image display device.

The structure is complicated, and the picture replacement process is complicated, so it cannot be used for structures that need to be replaced frequently, such as theater posters.

U.S. Patent No. 7.312.923 is a three-dimensional theater that moves the lens sheet left and right over the bearing structure, so that the two pictures can be viewed with a paralley effect and cannot be applied to a three-dimensional drawing device. It cannot be applied to mass replacement structures like posters.

US US Pub NO2010 / 018621 is a device that shows two pictures by moving the lens sheet left and right by a motor or an arcuate elastic element, and cannot be applied to a three-dimensional picture as in the present invention. It is not suitable for a structure that replaces only pictures such as a poster.

As described above, the conventional general techniques are both a device for moving two pictures in a poster or a structure for fixing a picture in a complex structure. There was no.
