Description

3D Glasses and Glasses Using the Same

The present invention relates to a spectacle lens capable of viewing a three-dimensional stereoscopic image (3D image) with a sunglasses function and glasses using the same, more specifically, each polarized axis and the phase difference axis of the polarizer is different from the usual sunglasses The present invention relates to a spectacle lens configured to enable viewing of a three-dimensional stereoscopic image and glasses using the same in a screen used as a function and supporting a 3D image.

In the technological development of 3D stereoscopic image, polarization method was developed in 1920s, optical hologram method was developed in 1948, polarized glasses were developed in 1980s, and various stereoscopic broadcasting services are being studied.

With the opening of the digital era, the current three-dimensional image is showing the line to the public, as well as three-dimensional image broadcasting, is gradually expanding. In the stereoscopic image, when the user wears glasses that selectively receive two stereoscopic images through the left and right eyes of the person, the person feels the stereoscopic sense of the image through the glasses. Such glasses are glasses for stereoscopic images.

On the other hand, the left and right eyes of a real person accept different images, and by automatically analyzing these different images in the brain, the 3D sense of three-dimensional space is felt through the human eye.

In this way, the factor of recognizing a 3D space is that a different image is incident through the left and right eyes. Therefore, due to this principle, two images must be taken to realize a stereoscopic image. Therefore, at least two stereoscopic image capturing images of images observed from different angles are separated and transferred to a display to realize stereoscopic images.

In addition, in order to view stereoscopic images with the left and right eyes, viewers viewing stereoscopic images should wear glasses for stereoscopic images, and the stereoscopic glasses for each image are provided with a filter function to display the two images displayed on the display. Accordingly, by performing the signal absorption in the differential direction, the viewer can view the respective selective images with the left and right eyes, thereby feeling the stereoscopic sense of the image.

In general, stereoscopic images use two-dimensional planar images in combination with other additional tools to give a feeling and sense similar to three-dimensional reality, or manipulate the image by physical and mechanical forces to illuminate the perspective or spatiality of the image. It is a video method that makes people feel by mistake. This 3D stereoscopic image is fundamentally based on the fact that humans have two eyes, and the principle that humans perceive objects in three dimensions is that the two eyes, which are horizontally spaced apart, retina from different angles. By accepting things through, two images are made by electric signal transmission to the cerebrum and synthesized.

The visual acuity of ordinary people provides perception of space in terms of color and three-dimensional (3D) observations. A good realization of the optical requirements for a photographic system that provides an observer with three-dimensional stereoscopic images or stereo models is achieved by visual recognition of stereoscopic images or spaces.

Stimulus conditions for spatial recognition are classified into two groups.

The monocular group allows stereoscopic images with one eye and includes the relative size of the subject, interference, linear and spatial perspectives, the distribution of light and darkness, and the parallax of movement between the subject, background, and visual perception.

The binocular group uses the two coordinated mobility of both eyes, which is due to the visual convergence where the optical axis converges strongly at a convergence angle of 23 ° at a point close to 150 mm from parallel for the remote vision and two different visual viewpoints. The geometric image is stereoscopic vision that provides two different retinal images for the left and right eyes.

The bodily sensation is perceived when both eyes of the person see the real world because of the different images on the retina due to the distance between the two eyes.

The inconsistency of the image that occurs in the retina is the horizontal distance to the same target point in the image projected on the retina.

Parallax, on the other hand, refers to the horizontal distance between two points of an image projected on a monitor, which is an important factor in determining the width of the discrepancy. A positive parallax is called a positive parallax when the observation point is farther than the solid plane and occurs when the distance between the eyes is less than or equal to the distance between the eyes. .

Negative parallax refers to the case where the parallax is closer than the three-dimensional plane, and occurs when the line of sight intersects and makes a sense of the protruding three-dimensional feeling. Research into realizing three-dimensional images using the characteristics of the human eye as described above has been steadily studied for a long time.

Due to a long period of research, recently, it has been realized that the glasses and imaging devices that are formed in the same way as general glasses are worn through the human eye. Looking at the product having a three-dimensional function as described above,

Application No. '10 -2003-0059794 'relates to a polarizing glasses device, wherein image information corresponding to parallax is disposed in an opposite relationship to an image display screen on which the image information corresponding to the parallax is separately displayed in the first area and the second area, and the image display screen. Polarizing glasses for viewing an image displayed on the image display screen of a three-dimensional image display device having a polarizing plate and a phase difference plate bonded to a position corresponding to the first area or the second area of the front surface of the polarizing plate to change the polarization direction. An apparatus comprising: a polarization separating means comprising a first coronal region for correlating with one eye of a left eye and a right eye and a second coronal region for correlating with a second eye while separating a specific polarization and a first polarization separating means First polarization direction converting means adhered to the first surface of the tubular region and a second side opposite to the first surface of the second tubular region of the polarization separating means; The second polarization direction converting means adhered to the surface is shown.

The general 3D glasses lens as described above has a problem that when the user wears, the dizziness may be felt when the reflection of the glass or mirror is seen as the direction of the phase difference axis and the polarization axis on the left and right sides are different. In addition, the 3D eyeglass lens had an uncomfortable point to be used as sunglasses because the polarization axes did not cross each other.

The present invention has been made to solve the above problems, the first polarizing plate and the second polarizing plate is formed continuously when forming the spectacle lens, wherein the polarization axis, the phase difference axis and the polarization axis of the second polarizing plate In order to make the phase difference axis orthogonal to each other, the color of the spectacle lens naturally occurs due to the diffraction of the light. It is an object of the present invention to provide glasses using the spectacle lens.

In the three-dimensional lens and glasses using the same to achieve the above object,

In the spectacle lens, a first coating paper made of polymethyl methacrylate (PMMA) and a first coating paper continuously formed after the first coating paper, and comprising a polarization axis of the polarizing plate and a phase difference axis formed at an angle with the polarization axis. A second polarizing plate and a second polarizing plate which are continuously formed after the first polarizing plate and have a polarization axis and a phase difference axis like the first polarizing plate, and have a polarization axis and a phase difference axis rotated by 90 ° with respect to the polarization axis and the phase difference axis of the first polarizing plate. A second coated paper which is continuously formed after the polarizing plate and the second polarizing plate and composed of polymethyl methacrylate (PMMA) is configured to be integrated. An optically transparent adhesive, which is an adhesive, is attached between the first coated paper, the first polarizing plate, the second polarizing plate, and the second coated paper. The first polarizing plate and the second polarizing plate may be configured as circular polarized light, respectively.

In addition, the angle between the polarization axis and the phase difference axis at the binding points of the first polarizing plate and the second polarizing plate may be formed between 75 ° and 105 °, respectively.

In the spectacles using the spectacle lens, it is configured to be perpendicular to each other when the phase difference axis of the 3D spectacle lenses respectively configured on both sides is extended.

According to the present invention, when the three-dimensional spectacle lens and the glasses using the same are used, the first polarizing plate and the second polarizing plate are continuously formed when the spectacle lens is formed, wherein the polarization axis, the phase difference axis and the second polarizing plate of the first polarizing plate The polarization axis and the retardation axis are orthogonal to each other, so that the color of the spectacle lens naturally occurs due to the diffraction of the light.It is usually used as a sunglasses function to filter out the glare of the light passing through the spectacle lens. When you wear a normal 3D glasses lens, you can feel dizziness when you see the reflection on the glass or mirror as the direction of the retardation axis and the polarization axis on the left and right sides are different, but can solve the dizziness due to the present invention, On the screen that supports 3D image, the spectacle lens and the spectacle lens for viewing in 3D stereoscopic image To provide yonghan glasses as it will invention is that high economy and efficiency.

When described in detail with reference to the drawings,

As shown in FIGS. 1 and 2, polarization axes 200 and retardation axes 300 are respectively provided on both sides of the 3D glasses lens 100 of the three-dimensional (3D) glasses 10 which are widely used. The phase difference axis 300 is formed at a predetermined angle on the polarization axis 200 but is orthogonal to the symmetry of the 3D glasses lens 100 configured to both sides, so that the image emitted from the stereoscopic image display device 400 is formed. It is common to see through eyes.

In explaining the principle of this, taking an example of watching stereoscopic images,

The 3D glasses 10 have a polarization axis 200 and a phase difference axis 300 of the 3D glasses lens 100. In the lens 410 of the stereoscopic image display device 400 that emits a stereoscopic image, the polarization axis 420 is attached to the horizontal polarization axis 421 and the vertical polarization axis 422, respectively.

When the stereoscopic image emitted from the stereoscopic image display device 400 reaches the 3D glasses lens 100 through the horizontal polarization axis 421 and the vertical polarization axis 422 of the stereoscopic image display device 400, the 3D glasses Since the phase difference axis 300 of the lens 100 is orthogonal, the wearer can check a stereoscopic image.

As described above, when the user wears the general 3D glasses lens 100, the direction of the polarization axis 200 and the phase difference axis 300 on the left and right sides are different, so the user may feel dizzy when they see the reflection on the glass or mirror. There is a problem that can be felt.

Referring to the present invention developed to solve the above problems based on the bar shown in Figures 3 to 5, in the spectacle lens 20, the agent consisting of polymethyl methacrylate (PMMA: Polymethyl Methacrylate) The first polarizing plate 30 is formed successively after the first coated paper 50 and the first coated paper 50 and comprises a polarization axis 31 of the polarizing plate and a phase difference axis 32 formed at an angle with the polarization axis 31. ) And the first polarizing plate 30 are continuously formed, and have a polarization axis 41 and a retardation axis 42, like the first polarizing plate 30, but have a polarization axis 31 of the first polarizing plate 30. ), The second polarizing plate 40 having the polarization axis 41 and the phase difference axis 42 rotated by 90 ° with respect to the phase difference axis 32 and the second polarizing plate 40 are continuously formed, and the polymethyl meta The second coated paper 60 composed of acrylate (PMMA) is integrated. In this case, the optically transparent adhesive 70, which is an adhesive, is attached to the first coating paper 50, the first polarizing plate 30, the second polarizing plate 40, and the second coating paper 60.

Polymethyl methacrylate (PMMA) used for the first coated paper 50 and the second coated paper 60 is commonly referred to as an “acrylic resin”, and researched and developed in the 1930s and started industrialization. It is the kind of resin that has the oldest history among the existing resins, and is the most transparent and weather resistant. Therefore, it is widely used in organic glass, electric parts and building materials.

The PMMA material is colorless and can transmit ultraviolet rays up to 270 nm without absorbing the full wave of visible light. In addition, the colorability is very good, it is possible to obtain a wide range of shades from pale to dark. In addition, there is a characteristic that does not discolor or fade even in heat or sunlight, the surface is glossy, light, and good chemical resistance is not eroded by strong alkalis and salts thereof.

It is also resistant to salts, fats and oils, and aliphatic hydrocarbons of organic sand, and has the best weatherability among plastics, and is widely used in windshields, optical lenses, glasses, and the like because of its good formability and processability.

The first polarizing plate 30 and the second polarizing plate 40 should be composed of circularly polarized light, respectively.

Here, circularly polarized light is light whose electromagnetic vibration of light waves is the original vibration. One component of the magnetic field or the electric field has a constant amplitude, but the vibration direction is rotated perpendicular to the traveling direction of the light. The angle of inclination of 45 ° to the main surface of the wave plate is sufficient. Conversely, when circularly polarized light passes through it, it becomes linearly polarized light.

In the case of linear polarized lenses, the angle of the lens is limited, so tilting your face while watching 3D images will damage the 3D image effect. For example, you can create a more natural viewing environment and watch a lot of people at the same time.

The angles between the polarization axes 31 and 41 and the angles between the phase difference axes 32 and 42 at the mutually binding points of the first polarizing plate 30 and the second polarizing plate 40 are between 75 ° and 105 °, respectively. It should be configured to be able to make the angle of.

In addition, in the glasses 10 using the spectacle lens 20 as shown in FIG. 5, when the phase difference axes 32 and 42 of the 3D spectacle lenses 20 and 20 'respectively configured on both sides are extended. It should be configured to be orthogonal to each other.

Referring to the operation according to the present invention sunglasses combined three-dimensional glasses lens configured as described above are as follows.

In the spectacle lens 20 as shown in Fig. 3 or 4,

An optical clear adhesive (OCA) 70 is attached to one surface of the first coated paper 50 made of PMMA, and is continuously formed after the optical clear adhesive 70, and the polarization axis of the polarizing plate is And a first polarizing plate 30 composed of a phase difference axis 32 formed at an angle with the polarization axis 31, and then attaching the optical transparent adhesive 70 to the optical transparent adhesive. It is continuously formed after the adhesive 70 and has a polarization axis 41 and a retardation axis 42, like the first polarizing plate 30, but has a polarization axis 31 and a retardation axis of the first polarizing plate 30. 32 is attached to the second polarizing plate 40 having a polarization axis 41 and a phase difference axis 42 rotated by 90 °, and the optical transparent adhesive 70 is attached again and then formed continuously. The second coating paper 60 made of a material is integrated to form the lens 20. In this case, the first polarizing plate 30 and the second polarizing plate 40 should each be composed of circularly polarized light.

In addition, when the first polarizing plate 30 and the second polarizing plate 40 are continuously attached, the polarization axes 32 and 42 are orthogonal to each other, and the color is applied to the spectacle lens 20 by diffraction of light. This is a natural color generated when natural light passes through each circular circular polarization in the 90 ° direction, and it can represent a natural and eye-free color even when no color is added to the spectacle lens 20. Naturally, you will also have sunglasses.

When the first polarizing plate 30 and the second polarizing plate 40 are bound to each other, the angle between the polarization axes 31 and 41 and the angle between the phase difference axes 32 and 42 are respectively between 75 ° and 105 °. 3D video can be viewed even if the angle is made, it is also possible to configure by applying this.

As described with reference to FIGS. 5 to 6, in the case of using the spectacle lens 20, the phase difference axes 32 and 42 of the 3D spectacle lenses 20 respectively configured on both sides are described. It is preferable to be configured to be orthogonal to each other when extending, but as described above, the angle and phase difference axis between the polarization axes 31 and 41 at the intersection point when the first polarizing plate 30 and the second polarizing plate 40 are mutually bound. The angle between 32 and 42 may be configured in this way because viewing of the 3D image is possible even when the angle is between 75 ° and 105 °, respectively.

The lens 20 configured to orthogonally cross the polarization axis 31 and the phase difference axis 42 formed in the first polarizing plate 30 and the phase difference axis 32 and the second polarization plate 40. The lens 20 'is configured to be symmetrical with the lens 20, but the polarization axis 31' and the phase difference axis 32 'of the first polarizing plate 30' and the polarization axis of the second polarizing plate 40 ' The 41 'and the phase difference axis 42' are orthogonal to each other so as to be a 3D glasses 10 capable of viewing 3D images.

The polarization axis of the general polarized sunglass is composed of 90 °, the 3D glasses lens 100 is composed of 0 ° and 90 °, respectively, it was inconvenient to use as sunglasses.

However, according to the present invention, the polarization axis 31 of the first polarizing plate 30 and the polarization axis 41 of the second polarizing plate 40 intersect each other to have a natural color and simultaneously transmit to the spectacle lens 20. Due to the light, the glare is further filtered out, eliminating direct fatigue in the eyes and providing comfort.

In addition, when wearing the conventional 3D glasses lens 100, the directionality of the phase difference axis 300 and the polarization axis 200 on the left and right side is different, the problem that could feel dizziness when seeing the reflection on the glass or mirror As shown in the present invention, dizziness is eliminated by allowing the polarization axes 31 and 41 of the first polarizing plate 30 and the second polarizing plate 40 to be 90 degrees apart.

In addition, according to the same principle as the spectacle lens 20 of the present invention to see another embodiment possible, depending on the angle of the polarization axis (31, 41) for TV, theater (0 °), monitor, notebook , Theater use (-45 °, + 45 °, 90 °), etc. In this case, the phase difference axes 32 and 42 should have a predetermined angle from the polarization axes 31 and 41.

According to the present invention, when the three-dimensional spectacle lens and the glasses using the same are used, the first polarizing plate 30 and the second polarizing plate 40 are continuously formed when the spectacle lens 20 is formed, wherein the first polarizing plate 30 The polarization axis 31, the phase difference axis 32 and the polarization axis 41 and the phase difference axis 42 of the second polarizing plate 40 are orthogonal to each other, so that color is naturally generated in the spectacle lens by diffraction of light. It is usually used as a sunglasses function, to further filter the glare for the light penetrating through the eyeglass lens 20 can have comfort for the eyes, the phase difference between the left and right sides when wearing the normal 3D glasses lens 100 As the direction of the axis 300 and the polarization axis 200 are different, the dizziness may be felt when looking at the reflection on the glass or the mirror, but the dizziness may be resolved due to the present invention, and the 3D image is supported on a 3D screen. Can watch in 3D Glasses may provide glasses with the lens and the spectacle lens so that it will as the invention their high economy and efficiency.
