Description

Glasses for viewing stereoscopic images and methods of viewing stereoscopic images using the same {GLASSES FOR WATCHING 3D IMAGE AND METHOD FOR WATCHING OF 3D IMAGE USING THE SAME}

The present invention relates to glasses for viewing stereoscopic images and a method of viewing stereoscopic images using the same.

3D display is simply defined as "the whole system of artificially reproducing 3D screens."

Here, the system includes both software technology that can be viewed in 3D and hardware that actually implements the content created by the software technology in 3D. The reason for including the software domain is that the 3D display hardware requires a separate software content for each stereoscopic implementation.

In addition, the virtual 3D display allows a user to literally feel a three-dimensional effect on a flat display hardware by using a binocular disparity, which appears when the human eye is about 65 mm apart in a horizontal direction, among other factors. The totality of the system. In other words, even though our eyes look at the same thing because of binocular parallax, each one sees a slightly different image (exactly, it shares some of the left and right spatial information), and when these two images are passed through the retina to the brain, the brain sees them. By fusion of each other precisely, we can feel a three-dimensional feeling, and it is a virtual 3D display that creates a virtual three-dimensional effect through a design that displays two left and right images simultaneously and sends them to each eye using a 2D display device.

In order to display two-channel images on one screen in such a virtual 3D display hardware device, for example, one channel is output one by one by changing a line in one direction of a horizontal or vertical direction. At the same time, when two channels of images are output from one display device, in the case of the autostereoscopic method, the right image enters the right eye and the left image only enters the left eye. In addition, in the case of wearing glasses, the right image is hidden from the left eye and the left image is hidden from the right eye through special glasses for each type.

Even if we print it out one by one like this, the thickness and spacing of the lines are very fine, about 0.1mm ~ 0.5mm, so our eyes don't notice the gap and the two images of each channel are displayed one by one. However, since the amount of information that enters the eye is divided into half for each channel, the resolution and the sensory brightness are reduced by about half compared to the 2D screen.

The display method of such a stereoscopic image includes a method of wearing glasses and a glasses-free method of not wearing glasses.

The method of wearing the glasses periodically repeats an anaglyph method using blue and red sunglasses on left and right, and a polarization method using polarized glasses with different left and right polarization directions and a time-divided screen. There is a liquid crystal shutter method using glasses equipped with a liquid crystal shutter to match the polarization method and the liquid crystal shutter method is mainly used. For reference, the polarization method and the liquid crystal shutter method have a difference in a method of separating left and right images, and the left and right images are separated through spatial division and time division, respectively.

In this case, the glasses for viewing stereoscopic images in the conventional method of wearing glasses have a disadvantage in that only one driving method can be viewed because they lack mutual compatibility due to the difference between the two types of driving methods. As a result, a problem arises that viewers can view only a single 3D image of the two methods.

Accordingly, the necessity of developing glasses for viewing stereoscopic images that can view both types of stereoscopic image display apparatuses with one pair of glasses is emerging.

Glasses for viewing stereoscopic images of the present invention having such a feature can watch 3D images in both the liquid crystal shutter method and the polarization type stereoscopic image display device, which will be described in detail with reference to the accompanying drawings.

4 is an exemplary view for explaining a stereoscopic image viewing method using a stereoscopic image display glasses according to the present invention with respect to the polarization type stereoscopic image display device.

Referring to FIG. 4, a polarization method uses a polarization phenomenon to spatially separate left and right images by arranging a patterned retarder 132 on the front of the screen of the display panel 130.

For reference, the pattern retarder 132 of the polarization type stereoscopic image display device refers to a film in which a predetermined pattern is formed according to a position so that left and right images can implement a polarization state having a direction perpendicular to each other.

In this case, the display panel 130 may include a liquid crystal display (LCD), a field emission display (FED), a plasma display panel (PDP), and an electroluminescent display (Electroluminescent). Display; EL). When the display panel 130 is configured as a liquid crystal display device, a polarizing film 131 having a light absorption axis in a horizontal direction is disposed between the display panel 130 and the pattern retarder 132. .

Currently widely used is a method of disposing the left and right images by line. That is, as shown, the left (L) image on the odd lines and the right (R) image on the even lines are arranged in the vertical direction. When the left and right (L, R) image is displayed on the display panel 130 as described above, the viewer wears the glasses 100 for viewing 3D images according to the present invention and separates the left and right (L, R) images to view the 3D image. You can enjoy it.

That is, when the viewer views the polarization type stereoscopic image display device, a voltage is applied to the liquid crystal layer 114 of the liquid crystal shutter panel 116 by turning off the power switch of the glasses 100 for stereoscopic image viewing. In this state, the quarter wave plate 112L of the left eye lens 110L and the quarter wave plate 112R of the right eye lens 110R of the glasses 100 for stereoscopic-vision viewing are in this state. For example, left and right (L, R) images polarized in different directions, for example, each consisting of a +1/4 wave plate and a -1/4 wave plate, for example, left-handed circularly. Polarized images and right-handed circularly polarized images are separated and transmitted. The light passing through the quarter wave plates 112L and 112R of the left and right lenses 110L and 110R having the ± 1/4 wave plate is in the same direction as the first linear polarizer 113 on the rear surface of the substrate 111. That is, the light is linearly polarized in the horizontal direction to transmit the first linear polarizer 113.

At this time, as the voltage is not applied to the liquid crystal layer 114 of the liquid crystal shutter panel 116 as described above, the light passing through the first linear polarizing plate 113 is a twisted nematic (TN) liquid crystal. The polarization direction is changed by 90 degrees through the first linear polarizer 113 and the second linear polarizer 115 perpendicular to the light absorption axis.

In this case, the circular polarization method is shown as the polarization method, for example, but the present invention is not limited thereto, and the linear polarization method may be used as the polarization method.

5A and 5B are exemplary views for explaining a stereoscopic image viewing method using the stereoscopic image viewing glasses according to the present invention with respect to the liquid crystal shutter type stereoscopic image display device.

5A illustrates that the left (L) image is driven in an even frame (N frame) so that the left (L) image is shown through the left eye lens 110L of the glasses 100 for viewing stereoscopic images. 5B illustrates that the right (R) image is driven in an odd frame (N + 1 frame), so that the right (R) image is shown through the right eye lens (110R) of the glasses 100 for viewing 3D images.

5A and 5B, the liquid crystal shutter method divides the left and right (L, R) images in time, and crosses the left and right (L, R) images on the screen of the display panel 140 for a short time. The 3D image is displayed by synchronizing the liquid crystal shutters to the display and the screen.

That is, the left and right lens 110L of the glasses 100 for viewing stereoscopic images in this state in a time division manner so that the left and right (L, R) image data are changed in units of frames (N frame, N + 1 frame). The right eye lens 110R is synchronized with the frames N frames and N + 1 frames to alternately turn on / off signal power, thereby enabling viewing of 3D images.

In this case, the display panel 140 is driven at 240 Hz higher than 120 Hz. Referring to FIG. 5A, for example, when the left (L) image is addressed for 4.2 ms, the liquid crystal moves according to an electric field. When the movement of the liquid crystal under the liquid crystal layer 114 ends, the left (L) image is viewed by opening only the left eye lens 110L of the glasses 100 for viewing 3D images. That is, the image output from the screen of the display panel 140 enters the two left and right lenses 110L and 110R. The liquid crystal shutter panel 116L for the left eye, to which no voltage is applied, rotates the incident polarization by 90 degrees to be orthogonal. As the second linear polarizer 115 passes through, the image signal enters the left eye. On the other hand, since the right eye liquid crystal shutter panel 116R to which the voltage is applied does not change the polarization direction, the image signal is blocked by the second linear polarizer 115 and thus cannot enter the right eye.

In addition, referring to FIG. 5B, in accordance with the synchronization of the display panel 140 and the glasses 100 for viewing 3D images, the right eye R 110R of the glasses 100 for viewing 3D images may be used in the same manner. By viewing the video, you can enjoy binocular disparity and enjoy 3D video. In other words, while changing the process of left and right alternately by providing parallax to the left and right (L, R) image to provide a three-dimensional effect.

At this time, the quarter wave plates 112L and 112R formed on the front surface of the substrate do not affect the left and right (L, R) image signals driven in the liquid crystal shutter type stereoscopic image display device.

For reference, in the liquid crystal shutter panels 116L and 116R of the glasses 100 for viewing 3D images, two linear polarizers 113 and 114 are disposed perpendicular to each other, and a transparent electrode (not shown) is attached therebetween. The glass substrate (not shown) is positioned, and the liquid crystal layer 114 is formed between the glass substrates to which the transparent electrode is attached.

Many details are set forth in the foregoing description but should be construed as illustrative of preferred embodiments rather than to limit the scope of the invention. Therefore, the invention should not be defined by the described embodiments, but should be defined by the claims and their equivalents.
