Description

Stereoscopic image display device {3D display apparatus}

The present invention relates to a stereoscopic image display apparatus, and more particularly, to a stereoscopic image display apparatus capable of widening the viewing range of an observer or a user by adjusting the arrangement position and width of barriers and slits constituting the barrier panel. will be.

In general, three-dimensional images that represent three-dimensional image is made by the principle of stereo vision through two eyes. The parallax of two eyes, that is, binocular disparity that appears because two eyes are about 65mm apart, is the most important factor of three-dimensional effect. This can be called. In other words, the left and right eyes each see different two-dimensional images, and when these two images are delivered to the brain through the retina, the brain accurately fuses them with each other to reproduce the depth and reality of the original three-dimensional image.

Currently, technologies proposed for displaying 3D stereoscopic images include a stereoscopic image display, a glassesless stereoscopic image display, and a holographic display method using special glasses. The three-dimensional image display method using the special glasses is a polarized glasses method using the vibration direction or rotation direction of the polarized light, time-division glasses method alternately presented while switching the left and right images and a method of delivering light of different brightness in the left and right Phosphorus concentration difference can be divided. In addition, the autostereoscopic 3D display method includes a parallax method and a semi-cylindrical lens arranged in front of each image corresponding to the left and right eyes to separate and observe the image through a vertical aperture. It can be divided into a lenticular method using a lenticular plate and an integral photography method using a lens plate shaped like a fly's eye.

In addition, the holographic display method can obtain a three-dimensional stereoscopic image having all factors such as focus adjustment, confinement angle, binocular disparity, and motion parallax that cause three-dimensional effect. Are classified.

The three-dimensional image display method by the special glasses, many people can enjoy the three-dimensional image, but has the disadvantage that you must wear a separate polarized glasses or liquid crystal shutter glasses. That is, the observer must wear special glasses, causing discomfort and unnaturalness.

The autostereoscopic 3D display method has a fixed observation range and is limited to a small number of people, but has a feature of not wearing a separate eyeglass.

Thus, there is an increasing tendency to adopt a parallax barrier, which is a method of realizing a three-dimensional image virtually through deception using stereo images.

The parallax barrier is a vertical or horizontal shape (slit) placed in front of an image corresponding to the left and right eyes so as to separate and observe a stereoscopic image synthesized through the slit to feel a three-dimensional effect. .

Here, the three-dimensional image display apparatus by the parallax barrier method will be described briefly as follows.

1 is a view showing that a three-dimensional image is implemented by a conventional barrier-type 3D display device.

As shown in FIG. 1, the conventional parallax barrier method includes an image panel 30 and a barrier panel 20, and the barrier panel 20 blocks slit through which light passes and blocks the light. The barriers are arranged in front of the image panel 30 in a structure arranged repeatedly.

The observer sees an image generated by the image panel 30 through the slit of the barrier panel 20. The observer's left and right eyes see different regions of the image panel 30, even though they pass through the same slit. The parallax barrier method uses this principle, so that the left eye and the right eye view images corresponding to pixels in different areas through the slit, so that a 3D feeling can be felt.

That is, in FIG. 1, the left eye LE sees the left eye corresponding pixel L in the image panel 30, and the right eye RE sees the right eye corresponding pixel R in the image panel 30.

However, the barrier panel 20 applied to the conventional stereoscopic display has a problem in that the left and right viewing ranges in which an observer can see a stereoscopic image are very narrow.

The method introduced to improve this is to make the gap between the barrier and the slit different. That is, as shown in FIG. 2, when the width of the barrier constituting the barrier panel 20 is larger than the width of the slit, it can be seen that the viewing range 50 in which an observer can view a stereoscopic image is considerably wider than in FIG. 1. Can be. However, in this case, a problem arises in that the image becomes dark instead of widening the field of view. Therefore, there is a need for improvement.

Accordingly, an object of the present invention is to provide a stereoscopic image display device that can overcome the above-mentioned conventional problems.

Another object of the present invention is to provide a three-dimensional image display device that widens the viewing range of the user (observer), but does not darken the image.

Still another object of the present invention is to provide a stereoscopic image display apparatus which can solve a problem of darkening an image while simultaneously widening a field of view by refracting an image.

And a barrier panel for converting the image emitted from the image into a stereoscopic image, wherein each of the slits constituting the barrier panel is formed of a convex lens having a predetermined curvature to deflect and transmit the image emitted from the image panel. .

The width of each of the plurality of barriers constituting the barrier panel may be equal to or larger than the width of each of the plurality of slits.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings without intending to intend to provide a thorough understanding of the present invention to a person having ordinary skill in the art to which the present invention belongs.

3 is a diagram illustrating that a 3D image is implemented by a stereoscopic image display apparatus according to a first embodiment of the present invention.

As shown in FIG. 3, the stereoscopic image display apparatus according to the first embodiment of the present invention includes an image panel 130 and a barrier panel 120, and the barrier panel 120 includes a slit through which light is transmitted.

That is, the barrier panel 120 is arranged in a structure in which a plurality of slits 120b and a plurality of barriers 120a are alternately arranged to convert an image emitted from the image panel 230 into a stereoscopic image.

The width of each of the barriers 120a constituting the barrier panel 120 may be equal to or larger than the width of each of the slits 120b.

Each of the slits 120b constituting the barrier panel 120 is provided as a convex lens having a predetermined curvature so as to refract and transmit an image emitted from the image panel 130. That is, each of the plurality of slits 120b may have a convex lens configuration. Accordingly, the plurality of slits 120b not only transmit an image (light) of the image panel 130 but also perform a role of refraction. In other words, the image passing through the slit 120b is refracted and collected.

In general, as shown in FIG. 4, when light emitted from a specific point A passes through the convex lens C, there is a property of gathering while forming one focal point f. For example, light emitted from a specific point A and passing through the upper end of the lens C, light passing through the center point of the lens C, and light passing through the lower part of the lens C are refracted to one. At the focal point (F).

If it passes through a transparent plate or glass, the light that passes through the top of the glass, the light that passes through the center of the glass, and the light that passes through the bottom of the glass are in focus at either focal point by the principle of light straightness. I can't gather.

After all, when using a convex lens, it is possible to brighten the image (light) in a specific area than when using a transparent body such as glass.

 By applying this principle, when the image emitted from the image panel 130 passes through the convex lens, it is possible to minimize the darkening of the image while widening the viewing range of the user and the observer.

That is, as shown in FIG. 3, when the slit 120b constituting the barrier panel 120 is formed of a convex lens, the darkening of the image can be minimized while widening the viewing range of the user and the observer. That is, the field of view 150 of FIG. 3 may be the same or wider than that of FIG. 2, and the image may be brighter.

 Here, the convex lens constituting the slit 120b has a shape of various convex lenses such that both sides of the image are convex with a constant curvature, or one side is flat or concave and the other is convex with a constant curvature. Can have And, the curvature or the refraction angle of the convex lens can be configured in various ways, if necessary,

The barrier panel 220 is disposed in front of the image panel 230 in a structure in which a slit 220b through which light is transmitted and a barrier 220a that blocks the light are repeatedly arranged. That is, the barrier panel 220 is arranged in a structure in which a plurality of slits 220b and a plurality of barriers 220a are alternately arranged to convert an image emitted from the image panel 230 into a stereoscopic image. The width of each of the barriers 220a constituting the barrier panel 220 may be equal to or larger than the width of each of the plurality of slits 220b.

The refracting panel 240 is disposed in front of the barrier panel 220 and is intended to refraction and transmit an image transmitted through the barrier panel 220.

The refractive panel 240 includes a plurality of convex lenses 240a corresponding to the number of slits 220b constituting the barrier panel 220. The plurality of convex lenses 240a may be arranged in a line to correspond to the plurality of slits 220b. For example, the plurality of convex lenses 240a are disposed such that an image transmitted through the plurality of slits 220b is refracted by the convex lenses 240a and transmitted.

The refractive panel 240 may have a structure in which the transparent plate and the transparent convex lens 240a are alternately arranged alternately. Of course, the convex lens 240a not only transmits an image (light) that has passed through the barrier panel 220 but also performs a role of refraction. In other words, the image is deflected and collected.

The principle of the convex lens and the image emitted from the image panel 230 by using the convex lens can brighten the image while widening the viewing range of the user and the observer, as described above with reference to FIGS. 3 and 4.

The darkening of the image can be minimized. That is, the field of view 250 of FIG. 5 may be the same or wider than that of FIG. 2, and the image may be brighter.

The refractive panel 240 may be disposed in front of the barrier panel 220, may be disposed to contact the barrier panel 220, or may be spaced apart from the barrier panel 220 by a predetermined interval. A distance between the refractive panel 240 and the barrier panel 220 may be variously changed.

In addition, the refractive panel 240 may be manufactured separately and configured to be detachable from the outside of the stereoscopic image display apparatus. For example, the stereoscopic image may be separately configured to be detachably attached to an external surface of the display screen on which the stereoscopic image of the stereoscopic image display device is output.

Here, the convex lens 240a constituting the refractive panel 240 may have a shape in which both sides of the image are convex with a certain curvature, or one side may be flat or concave, and the other may be convex with a certain curvature. It may have a shape of a convex lens. And, the curvature or the refraction angle of the convex lens can be configured in various ways, if necessary,
