Description

3D display device {THREE-DIMENSIONAL DISPLAY}

The present invention relates to a three-dimensional display device, and more particularly, to a three-dimensional display device for generating a three-dimensional stereoscopic image by separating the image information input to the left and right eyes of the viewer.

Three-dimensional display by binocular parallax, starting with a perspective painting of perspective in ancient Greek frescoes from about 100 BC, and by about 1,600 AD, the GB Della Porta of Italy seeing the picture with both eyes. Since the introduction of the first postcard, early researchers have been able to reproduce and enhance three-dimensional effects by Charles Wheatstone, England, David Brewster, Scotland, and Whendell Holmse, USA. It began in earnest, and in 1903, the FE Ives used parallax barriers to create stereoscopic stereograms, and in 1918, CW Kanolt began. A parallax panoramagram that secures this fixed defect so that continuous three-dimensional images can be seen. panoramagram).

The development of three-dimensional image media is not only the image field, but also related industrial effects affecting various fields from the home appliance and telecommunications industries, to the aerospace, arts, and automation industries. The ripple effect is expected to be far greater than HDTV (High Definition Television).

Thanks to the initial basic research as described above, not only the viewing of stereoscopic movies using polarized glasses is common today, but also various stereoscopic image generating techniques, which are largely represented by glasses and auto glasses, are known.

Some have actually been produced beyond the lab stage to include three-dimensional applied images, three-dimensional advertising production, three-dimensional television and video for cultural property preservation and display, computer vision, virtual world experience, simulation training and work, three-dimensional video conferencing, 3 It is partially applied to various fields such as dimensional graphics, 3D entertainment, and 3D movies.

The factors in which humans feel a sense of depth and depth include the physiological factors of vision coming from the characteristics of the eyes, as well as psychological / memory factors obtained from the retina and non-visual factors (hearing, smell, touch, etc.). The three-dimensional display technology can be classified according to the method of using, and the display capability by the degree of three-dimensional image information to the observer can be classified into a depth image system, a three-dimensional image system, and a three-dimensional image system. The display image is classified into a still image and a moving image according to whether there is motion.

First, the "depth image method" is a method in which a two-dimensional image has a three-dimensional effect in the space in the depth direction than the display surface due to psychological factors and suction effects.

The former is commonly used in three-dimensional computer graphics for displaying computationally displaying perspective, superposition, shading and contrast, motion, etc., while the latter is sucked into the space of the image by presenting the viewer with a large viewing angle. It is applied to a so-called IMAX film or the like which induces a three-dimensional effect by a wide-field stimulus by generating an illusion.

Next, the 'stereoscopic image method' represents spatial information before and after the display surface by separately observing an object observed from a direction corresponding to the left and right eyes, that is, two images with parallax, instead of confusing the left and right eyes. It's a way to make you feel three-dimensional.

This type of glasses uses special glasses with different characteristics with respect to the wavelength of light and polarization plane, and when images with parallax are presented on the same plane, each image is separated from side to side by putting a highly directional display plane on the plane. There is a display surface method, that is, a glasses-free method, which makes a person feel a three-dimensional feeling by entering the left and right eyes.

The spectacle glasses include a wavelength-selective sunglasses (color modulation) scheme, a polarization glasses scheme using a polarization difference shading effect, and a time-division glasses scheme alternately presenting left and right images within an afterimage time of an eye.

In addition, there is a method in which a filter having different transmittances in the left and right eyes is attached to obtain a three-dimensional effect on the movement in the left and right directions according to the time difference of the visual system coming from the difference in the transmittance.

They are not widely used due to the inconvenience of wearing special glasses, problems of hygiene, adverse effects on the human body, and the like.

In addition, there is a parallax stereogram method, a lenticular method, a corne cube mirror, and a holographic type in the autostereoscopic method, which generates a three-dimensional effect on the display surface rather than the observer side. There is a directional screen method using a holographic method or the like.

Depth and stereoscopic images reproduce only the information before and after (depth) of the object, so that the object cannot be observed in various directions that the observer observes or the object cannot be focused even if some observation is made. There is a problem with the way it is reproduced.

In order to solve this problem, the three-dimensional image method is representative of depth multi-eye, sampling method, and holographic display method, and the three-dimensional image method limits the viewing direction by reproducing a three-dimensional stereoscopic image in space. And some problems such as being unable to focus.

There are parallax barriers, lenticulars, and integrals.

The depth sampling method includes a display surface vibration method, a variable cylindrical mirror method, a rotating cylinder method, a display surface stacking method, and a semi-transmissive mirror synthesis method.

This method, which requires a mechanical moving part, is a display method using the afterimage time of the eye, and there is a problem in the scanning speed in order to display an image having a lot of depth information within the afterimage time.

In addition, display surface lamination and transflective mirror synthesis have a problem in that it is difficult to increase the number of depth images.

On the other hand, the holographic method is known as the most excellent method among the three-dimensional image display, which includes laser light regeneration holography and white light regeneration holography, but requires a large amount of data to display the object, and high cost to increase the spatial resolution There is a problem such as that.

Hereinafter, several methods of improving the understanding of the present invention among the three-dimensional image display methods according to the related art will be described.

1 is an exemplary view illustrating a lenticular lens array method, which is an example of a 3D image display method according to the related art.

In the lenticular lens array method, as illustrated in FIG. 1, the display surface 100 in which image information L to be input to the left eye 120 and image information R to be input to the right eye 121 are alternately arranged along the horizontal direction. ) And optical discrimination directivity of the image information L to be input to the left eye 120 and the image information R to be input to the right eye 121 interposed between the display surface 100 and the left and right eyes 120 and 121. It is composed of a semi-cylindrical lenticular lens array 110 to provide.

Images are separated into the left eye 120 and the right eye 121 according to the directivity characteristics provided by the lenticular lens array 110 so that they appear three-dimensional.

That is, the image information L to be input to the left eye 120 is observed only to the left eye 120, and the image information R to be input to the right eye 121 is only observed to the right eye 121, and thus, among the visual physiological factors. Three-dimensional effect is obtained by obtaining depth information through binocular parallax, which has a large effect of three-dimensional effect.

2 is an exemplary view showing a method using a slit, which is another example of a three-dimensional image display method according to the prior art.

The method using a slit is commonly referred to as a parallax method, and instead of using a lenticular array of semi-cylindrical lenses arranged, a parallax barrier 210 having a vertical lattice shape as shown in FIG. 2. In another method, the image information L to be input to the left eye 220 and the image information R to be input to the right eye 221 are alternately arranged along the horizontal direction. It is similar to the lenticular method in that the displayed display surface 200 is used.

At this time, the parallax barrier 210 allows the image to be separated and observed through an aperture of a vertical grid in front of the L and R images corresponding to the left and right eyes 220 and 221.

3 is an exemplary view showing a method using a variable focus mirror, which is another example of a display surface vibration rotating method according to the related art.

The method using a variable focal mirror—or a method using vibration optics—has been proposed since 1961 by T. Muirhead, which has been proposed as shown in FIG. A thin film mirror is attached to the surface of the vibrating speaker 260 to provide an observation of the cutting plane of the object formed on the monitor 270 such as a cathode ray tube (CRT) through the mirror so that the internal image can be seen. Phantom imaging effect is used.

Accordingly, the observer 250 senses a three-dimensional effect by observing the virtual image 280 of the monitor.

On the other hand, a three-dimensional stereoscopic image generating apparatus using a laminated liquid crystal display has been proposed to generate a three-dimensional image by reconstructing a two-dimensional slice image generated based on a variable focus into a three-dimensional image through a stacked liquid crystal display device. .

In order to reproduce the three-dimensional effect on the optical image, the laminated liquid crystal display device sequentially displays each two-dimensional slice image acquired sequentially according to the depth information, and the three-dimensional image is interposed between the laminated liquid crystal display device and the observer through an enlarged lens unit. It is characterized by generating an image.

The barrier plate 33 is configured to block light at the inclined surface of the barrier wall 34 so that only the eye of the side is reached and not the other eye.

The image display 30 is driven by the display driver 35 to display image information to be input to the left eye 1 in the left eye image pixel 31, and the right eye 2 in the right eye image pixel 32. Image information to be inputted is displayed, and the plurality of left eye image pixels 31 and the plurality of right eye image pixels 32 are configured to be alternately arranged along a horizontal direction (horizontal direction).

That is, the image display 30 is a display panel in which a plurality of left eye image pixels 31 and a plurality of right eye image pixels 32 are alternately arranged, and in the horizontal direction, the left eye image pixel 31 and the right eye image pixel. 32 are alternately arranged, and the same kind of pixels are arranged in the vertical direction, so that when viewed from the front of the image display 30, a plurality of vertical bands formed by two types of vertical bands, that is, the left eye image pixels 31 are formed. A plurality of vertical bands formed by the band and the right eye image pixel 32 are alternately arranged.

The image display 30 may be various displays such as LCD, OLED, PDP, CRT.

The display driving device 35 includes an image input unit 36 which provides an image signal to be input to the left eye 1 and an image signal to be input to the right eye 2 according to the pixel to the image display 30, and the image input unit. And a display driving control unit 37 for controlling the driving of the image display 30 so that each pixel displays the image signal provided by 36. FIG.

The barrier plate 33 has a structure in which a plurality of blocking walls 34 are arranged side by side on the front surface.

The blocking wall 34 may be implemented in a structure in which a V-shaped groove that blocks light by a light blocking material is formed side by side, and a rear surface of the barrier wall 34 is bonded to a front surface of the image display 30. Has a structure laminated on the image display 30.

In more detail, the barrier plate 33 has a structure in which a plurality of blocking walls 34 formed long in a vertical direction on a front surface thereof are formed side by side at a predetermined interval, and the plurality of blocking walls have a structure in which a V-shaped groove is formed side by side. (Hereinafter, referred to as a V-shaped barrier wall) 34 is implemented, a plurality of V-shaped grooves are formed at regular intervals as shown in FIG. 8 so that when viewed in a cross section, a trapezoid is formed in front of the image display 30. The shape becomes a structure which repeats along a horizontal direction (horizontal direction).

In the barrier plate 33, each of the V-shaped grooves is formed on the basis of each boundary of the image display pixel composed of the left eye image pixel 31 and the right eye image pixel 32. The light-blocking coating is coated to form a V-shaped blocking wall 34 that blocks the light of the image display 30, wherein the material of the barrier plate 33 is made of a transparent material and the two adjacent V The part between the magnetic shield walls 34 becomes a part through which light passes.

The barrier plate 33 may be manufactured by first forming V-shaped grooves in a vertical direction side by side at a predetermined interval on the surface of a substrate made of a transparent material, and then coating a light-blocking paint on each inclined surface that is a side of each V-shaped groove. Can be.

Referring to FIG. 8, when two neighboring pixels, that is, the left eye image pixel 31 and the right eye image pixel 32 are paired, one trapezoid in which a V-shaped barrier wall 34 is formed in front of each pair is positioned. It is structured.

In the display device of the present invention in which the barrier plate 33 having the above-described structure is used, as shown in FIG. 9, the image information displayed on the left eye image pixel 31 has a barrier plate between adjacent V-shaped blocking walls 34. 33) The light is blocked by the inclined surface of the V-shaped blocking wall 34 through the inside and reaches only the left eye 1, and the left eye 1 image information reaches the right eye 2. It doesn't work.

Also, the image information displayed on the right eye image pixel 32 passes through the barrier play between the V-shaped blocking walls 34 and reaches only the right eye 2, and the left eye 1 has the V-shaped blocking wall 34. While the light is blocked by the inclined surface of the right eye 2, the image information does not reach the left eye 1.

As shown in FIG. 9, the angle and height of the inclined plane of the V-shaped barrier wall should be set in consideration of the angle of the display, the angle of the left or right eye, the pixel size, and the like.

In other words, the angle and height of the inclined plane of the V-shaped barrier wall should consider the position of both eyes, the position of the pixel, and the pixel size, and obtain optimal results when considering the distance between the display and the eye and the distance between the left and right eyes. Can be.

* In the end, according to the barrier plate 33 as described above, the left and right eye images displayed on the rear image display 30 reach only the corresponding eye of the viewer and not the opposite eye, From the viewer's point of view, the images of the left and right eyes are separated so that the user can feel a three-dimensional effect.

In the above-described embodiment of FIG. 8, the barrier plate 33, that is, the barrier for allowing the left and right eye images to be distinguished and visible in the viewer's eyes is very easy to install.

In addition, when the pixel size of the image display 30 is reduced, the height (barrier plate thickness) of the V-shaped barrier wall 34 may be adjusted. FIG. 10 is a left eye image pixel 31 of the image display 30. ) And the size of the right-eye image pixel 32 is reduced to reduce the height of the V-shaped blocking wall 34.

In another preferred embodiment, when the front surface of the barrier plate, which is the front surface of the display device, is formed with V-shaped grooves (when each V-shaped blocking wall is formed by thinly coating a light blocking coating on the side of each V-shaped groove), In order to solve this problem, as shown in the accompanying FIG. 11, the transparent coating layer 34a, which fills the inside of each V-shaped groove, is coated with a light shielding paint. It may be further formed on the front surface of the barrier plate 33 including the portion, so that the entire front surface of the barrier plate 33 may be a flat and smooth surface.

As another method for configuring the barrier wall 34 of the barrier plate 33, the angle inclined at a V-shaped angle in cross section with respect to the barrier plate 33 with respect to the boundary of each pixel 11 of the image display 30. In order to form the barrier wall 34, grooves parallel to the surface of the transparent substrate, which is the material of the barrier plate 33, are formed long in the vertical direction, and two adjacent grooves are formed in the inclined direction to form a V-shaped angle in cross section. Then, by filling the light-blocking material in each of the grooves, it is possible to form the blocking wall 34 inclined at the V-shaped angle in cross section. However, since the height of the blocking wall changes according to the position of the pixel, the height of the transparent substrate should be determined in consideration of this point.

Here, a groove is not formed in a predetermined portion of the upper end portion and the lower portion of the substrate, and thus a groove is formed leaving the upper portion and the lower portion portion as described above, and then the light blocking material is filled only in a section in which the groove is formed.

In this case, when viewed from the front of the barrier plate 33, the light blocking materials filled in two rows form an angle blocking wall (34 in FIG. 12) inclined at a V-shape, and eventually at a V-shape. Each of the inclined blocking walls 34 is formed by coating a light blocking material on two inclined surfaces corresponding to the side surfaces of the V-shaped grooves as in the example of FIG. 11.

In addition, as shown in FIG. 12, a transparent coating layer 34a is further formed on the front surface of the barrier plate 33 in a state where the light blocking material is filled in the respective V-shaped grooves, thereby forming the barrier plate 33. It can also be configured so that the entire front face is flat and smooth.

Further, as another method for configuring the barrier wall 34 of the barrier plate 33, as shown in the cross-sectional view of FIG. 14 and the front view of FIG. 15, a plurality of V-shaped grooves parallel to the transparent plane are elongated vertically. After the formation, by filling the light blocking material in each V-shaped groove, the entire front surface of the barrier plate 33 may be configured to be a flat and smooth surface. In this case, the same effect may be obtained. However, the height of the barrier wall varies depending on the pixel position, so this should be considered.

In this case, in order to prevent contamination due to dust, the surface coating layer 34a may be further formed by using a transparent material on the front surface of the barrier plate 33 including the portion filled with the light blocking material.

In this manner, in the present invention, the three-dimensional display can be configured with a simpler configuration than in the related art.

In the above description of each embodiment of the present invention, the inclination angle and height of the blocking means such as the blocking display 15 and the blocking wall 34, and the inclination angle and height of the serrated image display 21 are determined by It is determined by the position, the distance between the two eyes (1, 2) (the distance between the left eye and the right eye), and the distance between the display and the user's eyes, where the user's eyes (1, 2) are located at the center of the display. Assumed

In real situations, there may be a difference in distance between the eyes of each person and a difference in the distance between the display and the user's eyes. In this case, the amount of light reaching both eyes decreases, and the light to be blocked reaches the left or right eye. This may cause problems.

Therefore, finding the optimal viewing position is a very important issue for maximizing the stereoscopic feeling of the 3D image, so that the user selects the optimal position while displaying the left eye image and the right eye image alternately by finding the optimal viewing position. It can be done.

That is, when the user presses the viewing position selection button (reference numeral 19a in FIG. 16), the 3D display apparatus of the present invention may alternately display the left eye image and the right eye image that the user can distinguish.

In this case, the image for the left eye and the image for the right eye may be distinguished from each other or images including specific text that may be distinguished from each other (eg, 'this is the image for the left eye', 'this is the image for the right eye', etc.). Colors may be represented by the corresponding pixels.

The viewing position selection button 19a may be installed on the display as shown in FIG. 16 when the distance between the user and the display (a display device such as a monitor or a mobile terminal of a PC) is close to each other. If the distance is farther than the arm's length, it can be installed on the remote control.

Referring to each embodiment, as shown in Figs. 4 and 16, when the viewing position selection button 19a is installed, the viewing position selection button 19a is for blocking the image display driving device 12. The display driving device 18 is provided to enable a signal input, and when the user presses the viewing position selection button 19a, the image display driving device 12 and the blocking display driving device 18 respectively receive signals. The driving of the display 10 and the blocking display 15 is controlled as follows.

That is, when the user presses the viewing position selection button 19a, the pixels 11 of the image display 10 alternately display the left eye image and the right eye image, and the blocking display 15 also uses the image. In synchronization with the display, the left eye blocking pixels 16 and the right eye blocking pixels 17 are alternately driven.

As another method, a stereo image (ie, a stereoscopic image having a clear sense of distance, etc.) that can be easily positioned can be displayed to allow a viewer to select an optimal position.

In this case, when the pixels 11 of the image display 10 display a specific image including a distinguishable text or an image of a distinguishable color (eg, red) as a left eye image, the right eye blocking of the blocking display 15 is performed. All the pixels 17 are driven to be displayed in black to block light, and the image is transmitted only to the left eye through the left eye blocking pixels 16.

On the contrary, when the pixels 11 of the image display 10 display a specific image including a distinguishable text or an image of a distinguishable color (eg, blue) as a right eye image, the left eye of the blocking display 15 All of the blocking pixels 16 are driven to display black to block light, and the image is transmitted only to the right eye through the right eye blocking pixels 17.

In this way, the user presses the viewing position selection button 19a and adjusts his / her eye position from the display back, front, left, and right to check whether the left eye image is seen only in the left eye and the right eye image is seen only in the right eye. In the state where the image for the right eye and the image for the right eye are found only in the left eye and the right eye, respectively, the 3D stereoscopic image provided by the 3D display device can be optimally viewed. The display can be moved in the front, rear, left, and right directions in the same manner, and a joystick and a driving motor can be used for this purpose.

At this time, as the user presses the viewing position selection button 19a, the corresponding display driving devices 12 and 18 control the driving of the image display 10 and the blocking display 15 as described above.

In addition, when the viewing position selection button 19a is installed in the embodiment of FIG. 6, the viewing position selection button 19a is provided to enable a signal input to the display driving device 24, and the user views the viewing position selecting button 19a. When pressing the display driving device 24 receives a signal to control the drive of the sawtooth image display 21 as follows.

That is, when the user presses the viewing position selection button 19a, the left eye image pixels 22 and the right eye image pixels 23 of the sawtooth image display 21 are alternately driven to drive the left eye image and the right eye image. The image is alternately displayed, and the user presses the viewing position selection button 19a in the same manner as in the embodiment of FIG. 4, and adjusts his eye position back and forth from the display while the left eye image is only visible to the left eye. You will see if the image is visible only in your right eye.

The 3D stereoscopic image provided by the 3D display device can be viewed in a state where the left eye image and the right eye image are found only in the left eye and the right eye, respectively.

In addition, when the viewing position selection button 19a is installed in the embodiment of FIG. 8, the viewing position selection button 19a is provided to enable a signal input to the display driving device 35, and the user selects the viewing position selecting button 19a. When pressing the display driving device 35 receives a signal to control the driving of the image display 30 as follows.

That is, when the user presses the viewing position selection button 19a, the left eye image pixels 31 and the right eye image pixels 32 of the image display 30 are alternately driven to alternate between the left eye image and the right eye image. In the same manner as in the previous embodiment, the user finds a position where the 3D stereoscopic image can be viewed and views the image.

On the other hand, the inclination angle and height of the blocking means such as the blocking display and the blocking wall, and the distance between the two eyes of the user (the distance between the left and right eyes) and the display and The amount of light reaching both eyes decreases due to the distance and relative position between the user's eyes (see FIG. 17), and the light to be blocked reaches the left or right eye.

Referring to FIG. 17, this illustrates a light quantity problem that may occur in the embodiment of FIG. 4 to which the blocking display 15 is applied, wherein an image displayed on each pixel of the image display 10 is displayed on the blocking display 15. The left eye blocking pixel 16 may cause a problem that some of the user's right eye 2 located closer to the display does not reach all but is partially hidden.

In FIG. 17, it can be seen that the dotted line continues from the front right eye 2 ′ to the respective pixels of the image display 10 instead of to the boundary of each pixel of the image display 10.

This means that a part of the image (area outside the dashed line) displayed by the pixels of the image display 10 is blocked by the left eye blocking pixels 16 without reaching the right eye 2 ′ of the user.

And, according to the distance between both eyes of the user and the distance between the display and the user's eyes, the image to be input to the left eye should be blocked for the right eye by the blocking means, and the image to be input to the right eye should be blocked for the left eye by the blocking means. In addition, a problem may occur in which an image to be input to the left eye reaches the right eye and an image to be input to the right eye respectively.

As such, when the user's eye position is too close or too far from the display, and when the distance between both eyes of the user is too close or too far from the current position, light arrival problems may occur. As a method of solving the problem of reaching, a method of reducing the pixel size or increasing the height of the blocking means may be used.

In this case, however, the amount of light reaching both eyes decreases.

Therefore, it is possible to select a method of adjusting the pixel size and the height of the blocking means according to the use conditions.

For example, in the embodiment of FIG. 4 using the blocking display as shown in FIG. 18, two or more blocking means different in angle and height may be installed on the assumption that the distance between the user and the display is two or more.

That is, as shown in FIG. 18, the left eye blocking pixels 16a and 16b and the right eye blocking pixels 17a and 17b are classified into two types according to the inclination angle and the height.

Referring to FIG. 18, two blocking displays 15a and 15b are stacked on a front surface of an image display 10 such that pixels 16a and 16b having different inclination angles and heights inward and outward from each pixel position are illustrated. , 17a, 17b are provided.

That is, for each pixel, the left eye blocking pixels 16a having a relatively small inclination angle and a low height inside the left eye blocking pixels 16b having a high inclination angle and a high height block the right eye having a high inclination angle and a high height. The right eye blocking pixels 17a, which have a relatively high inclination angle and a high height, are provided inside the dragon pixels 17b.

As a result, in the state where both eyes 1 'and 2' of the user are located closer to the display, the left eye blocking pixels 16a and the right eye blocking pixels 17a having a small inclination angle and a low height are used. In the state where both eyes 1 and 2 are located farther back from the display, the left eye blocking pixels 16b and the right eye blocking pixels 17b having a high inclination angle and high height are used.

Thus, by selectively driving left and right blocking pixels 16a and 16b and right and right blocking pixels 17a and 17b having different inclination angles and heights, the two eyes are positioned at a position near the user's binocular position and a position far from the display. All three-dimensional images can be viewed in an optimal state.

In order to select and drive one of the two blocking displays 15a and 15b, a selection button 19b can be installed on the display (in the case of a PC monitor) as shown in Fig. 16, and the distance between the user and the display The select button 19b may be installed in the remote control for cases longer than the arm length.

As shown in FIG. 17, the select button 19b is provided to enable a signal input to the display driving device 18 for blocking, and the user wants to drive according to his / her eye position using the select button 19b. When the displays 15a and 15b are selected, the blocking display driving device 18 drives the blocking display selected by the selection button 19b.

Attached FIG. 19 shows a state of using the outer blocking display 15b that is suitable when the user is located at a long distance, and FIG. 20 is attached to the inside blocking display according to the user when the user is located at a short distance. It shows the state using 15a).

Of course, in order to select the blocking display (15a, 15b) for the eye position, the user adjusts his eye position using the viewing position selection button (19a) and the selection button (19b) for the left eye image and right eye The position where the image is divided and the blocking displays 15a and 15b should be selected.

As described above, two or more blocking means having different angles may be installed on the assumption that the distance between the user and the display is two or more, and as shown in FIG. 21, the angle between the two eyes of the user may be two or more. Alternatively, two or more blocking displays 15a and 15b may be installed.

4 and 8, each pixel of the blocking display serving as a blocking means by reducing the size of the pixels (left eye blocking pixels and right eye blocking pixels in the embodiment of FIG. 4). It is also possible to adjust the size of the blocking wall (the embodiment of FIG. 8).

In addition, as an example of modifying the embodiment of FIG. 4 using a blocking display, the accompanying FIGS. 22 and 23 may adjust the length of each pixel of the blocking display to adjust a three-dimensional stereoscopic image even if the user's position and conditions are somewhat changed. An example (an example when limiting the distance between the two eyes to two cases) is shown that makes it possible to effectively provide a.

22 and 23 are additional blocking devices disposed in a V-shape at respective jagged vertices formed by adjacent left eye blocking pixels 16c and right eye blocking pixels 17c in the blocking display 15. The pixels 16d and 17d are provided, and each additional blocking pixel 16d and 17d is installed on an extension line of the existing blocking pixels 16c and 17c to further block the existing blocking pixels 16c and 17c. The pixels 16d and 17d may serve as one blocking pixel.

That is, the existing left eye blocking pixel 16c and the left eye blocking pixel 16d on the extension line are one left eye blocking pixel 16, and the existing right eye blocking pixel 17c and the right eye blocking line on the extension line. The pixel 17d may be driven by one right eye blocking pixel 17. The pixel 17d may include a left eye blocking pixel 16 including an additional blocking pixel 16d and an additional blocking pixel 17d. The end of the right eye blocking pixel 17 intersects.

In the blocking display structure, the existing blocking pixels 16c and 17c and the additional blocking pixels 16d and 17d are independently driven by the blocking display driver 18, for example, the left eye blocking pixel 16c. Alternatively, only the existing right eye blocking pixel 17c is driven to block an image displayed on each pixel 11 of the image display 10, or the existing left eye blocking pixel 16c and the additional left eye blocking pixel 16d are blocked. Drive together to block the right eye image of the image display 10, or the existing right eye blocking pixel 17c and the additional right eye blocking pixel 17d are driven together to block the left eye image of the image display 10. Can be.

Referring to FIG. 22, when the distance between both eyes 2 ′ of the user is relatively far, only the left eye blocking pixel 16c and the right right eye blocking pixel 17c are alternately driven. While the image to be input to the left eye is displayed on each pixel 11, the existing right eye blocking pixel 17c is driven to block light, and an image to be input to the right eye to each pixel 11 of the image display 10 is displayed. While being displayed, the existing left eye blocking pixel 16c is driven to block light.

On the other hand, if the distance between both eyes 2 'of the user is relatively close, the existing left eye blocking pixel 16c and the additional left eye blocking pixel 16d on the extension line are driven together to block light at the same time, and block the existing right eye. The pixel 17c and the additional right eye blocking pixel 17d on the extension line are driven together to block light at the same time.

That is, the existing left eye blocking pixel 16c and the additional left eye blocking pixel 16d on the extension line are driven by one left eye blocking pixel 16, and the existing right eye blocking pixel 17c and the additional right eye on the extension line are driven. The blocking pixel 17d is driven by one right eye blocking pixel 17, and at this time, the left eye blocking pixel (the existing left eye blocking pixel + an additional left eye blocking pixel on its extension line) 16 and the right eye blocking pixel The pixels (an existing right eye blocking pixel + an additional right eye blocking pixel on its extension line) 17 are alternately driven.

At this time, while the image to be input to the left eye is displayed on each pixel 11 of the image display 10, the existing right eye blocking pixel 17c and the additional right eye blocking pixel 17d on the extension line are driven together to simultaneously display the light. While the image to be input to the right eye is displayed on each pixel 11 of the image display 10, the existing left eye blocking pixel 16c and the additional left eye blocking pixel 16d on the extension line are driven together. At the same time it blocks the light.

By increasing the length of each pixel of the blocking display 15 as described above, it is possible to effectively provide a three-dimensional stereoscopic image even if the relative positions of both eyes change slightly.

FIG. 23 is a diagram showing an example in which the length of the blocking means can be reduced when the distance between both eyes is limited to two cases.

Next, FIG. 24 is a view showing an embodiment in which the size of each pixel of the blocking display is further reduced, and shows an example of reducing the length of the blocking means.

Referring to FIG. 24, in response to a decrease in the size of each pixel 11 of the image display 10 in which an image to be input to the left eye and an image to be input to the right eye are alternately displayed, the blocking display 15 may be disposed on an inclined surface. It can be seen that the size of the positioned left eye blocking pixel 16 and right eye blocking pixel 17 are reduced.

It can also be seen that the barrier wall does not have to be adjacent to the image display as shown. However, in this case, there is a disadvantage in that the screen becomes dark due to the decrease in the amount of light.

As described above, the various types of three-dimensional display apparatuses proposed by the present invention have been described. When the blocking means on the front surface is removed, the display apparatus can be used as a general display.

To this end, the blocking displays 15, 15a and 15b disposed in front of the image display 10, and the barrier plate 21 disposed in front of the sawtooth image display 20 are provided for the image display 10,. It can also be installed in a structure detachable from 20).

In addition, after manufacturing and providing a plurality of blocking displays or barrier plates that vary the blocking angle (such as the blocking pixel and the inclined angle and height of the blocking wall) in consideration of the distance between the user and the display and the distance between the eyes of the user. It is possible to attach and use an appropriate blocking display or barrier plate depending on the conditions.
