3D stereoscopic image technology, which is the focal point of next-generation 3D information terminal technology, is expected to have a wide range of added value as it is expected to have a wide range of influences in almost all industries such as entertainment, aerospace, military, medical, and film. This is expected. 3D stereoscopic technology has been actively researched in domestic and overseas research institutes and educational institutions since Charles Wheatstone, UK, announced stereoscope in 1838.

3D stereoscopic technology is classified into a stereoscopic stereoscopic method using two left and right two-dimensional images and a holographic three-dimensional method using scattering information of an object. The holographic method is the ultimate 3D input / output method that reproduces natural stereoscopic images using scattered light from an object, but due to the limitation of the vast amount of 3D information and related devices, it has limitations that cannot be realized in real time with current transmission system. have.

In general, the three-dimensional sense perceived by a person is caused by the degree of change in the thickness of the lens depending on the position of the object to be observed, the difference in angle between the two eyes and the object, the difference in the position and shape of the visible object in the left and right eyes, and the movement of the object. Lag and other effects such as various psychological and memory effects are produced in combination. Among them, binocular parallax, which appears as two eyes of a person are located about 6 ~ 7cm apart in the horizontal direction, can be said to be the most important factor of three-dimensional effect. In other words, the binocular parallax makes us look at the angle with respect to the object, and because of this difference, the images coming into each eye have different images, and when these two images are transmitted to the brain through the retina, the brain receives these two pieces of information. You can feel the original 3D stereoscopic image by fusion with each other exactly. Using this method is a stereoscopic stereoscopic method.

The stereoscopic stereoscopic image method mainly uses specially manufactured glasses, and the spectacle type uses a color filter method that separates and selects an image using a color filter having a complementary color relationship, and a light blocking effect by a combination of polarizing elements. Polarization filter method that separates the image of the left and right eyes, and shutter glass method to feel the three-dimensional effect by alternately blocking the left and right eyes in response to the synchronization signal projecting the left and right eye signals to the screen. do.

In particular, the polarizing filter method is a method adopted by a general 3D movie theater, and can provide 3D glasses at a lower cost than a shutter glass method, and shows an advantage in use, such as no flickering. However, such polarized filter type 3D glasses also have a problem in that a user who needs vision correction needs to wear glasses for correcting vision twice.

Accordingly, an object of the present invention is to provide a 3D glasses lens and a 3D glasses having the same polarization filter method that can correct the vision.

In order to solve the above problems, the present invention is a curved 3D film; And a lens for correcting vision of a curved shape attached to both surfaces of the 3D film.

In a preferred embodiment of the present invention, the 3D film may include a polarizing film, a polarizing protective film and a compensation film, it may be used that these films are laminated.

Although the kind is not specifically limited as such a polarizing film, Polyvinyl alcohol etc. can be used. In addition, although the kind is not specifically limited as said polarizing protective film, Triacetyl cellulose etc. can be used. The compensation film used in the present invention may use polycarbonate or norbornene copolymer resin, but is not particularly limited thereto.

In addition, in order to solve the above problems, the present invention is a curved 3D film; And a lens for correcting vision of a curved shape attached to both surfaces of the 3D film.

In a preferred embodiment of the present invention, the 3D film may include a polarizing film, a polarizing protective film and a compensation film, it may be used that these films are laminated.

3D stereoscopic technology is classified into stereoscopic stereoscopic method using two left and right two-dimensional images and holographic three-dimensional method using scattering information of an object, and stereoscopic stereoscopic methods generally generate binocular disparity. You will use 3D glasses to make it work. The stereoscopic stereoscopic image system has a polarization filter method and a shutter glass method, and can provide 3D glasses at a low cost, and there are advantages in using such flickering. However, polarized 3D glasses also have a problem in that a user who needs vision correction needs to wear double vision glasses. Since the lens for 3D glasses of the present invention uses a vision correcting lens, the vision correction can be performed simultaneously with the function of the 3D lens. Therefore, in the case of using the lens for 3D glasses of the present invention, a user who needs to wear the glasses for correcting vision does not need to wear the 3D glasses in order to consume 3D content.

Although not limited, a polyvinyl alcohol film or the like can be used. The polyvinyl alcohol film (Poly Vinyl Alcohol, PVA) is uniaxially stretched to cultivate the polymer chain in the stretching direction, and the iodine molecules or dichroic dye molecules having dichroic dyes on the stretched polyvinyl alcohol film side by side in the stretching direction By arranging the function is obtained. The dichroic iodine molecule and the dye molecule are arranged in parallel with the stretching direction to transmit light oscillating in the stretching direction.

The polarizing protective film 21 serves as a protective member of the polarizing film 22, but the type thereof is not particularly limited, and a triacetyl cellulose (TAC) film may be used. The polarizing protective film 21 may be used in the form bonded to one or both sides of the polarizing film 22, the surface of the polarizing protective film 21, scattering, hardness enhancement, antireflection, low reflection, etc. according to the required characteristics Surface coating treatment having the characteristic of may be added.

The compensation film 23 serves to correct or correct polarization characteristics by changing a phase difference of light polarized from 3D content displayed by polarizing images of left and right eyes, but the type of polycarbonate is not particularly limited. Or a film containing a norbornene copolymer resin or the like can be used. For example, the compensation film 23 may convert circularly polarized light into linearly polarized light.
