Description

Technical Field [0001] The present invention relates to a digital information display device capable of simultaneously implementing 2D and 3D,

The present invention relates to a digital information display device capable of simultaneously implementing 2D and 3D, and more particularly, to a digital information display device capable of providing various information simultaneously as a 2D image and a 3D image, To a digital information display device capable of simultaneously realizing 2D and 3D in which visibility is improved by minimizing a dead zone by using a barrier.

Digital Information Display (DID) is used to advertise and advertise products at branch offices such as department stores, or to provide various information such as location information and related explanations in public buildings.

However, the conventional digital information display device only provides the information through the two-dimensional image, so that the specific information can not be provided more efficiently and accurately through the three-dimensional image.

Meanwhile, in recent years, a technology for disposing a barrier in an image display device has been used so as to provide a spectacle-free 3D image display device in a general display device field other than the DID.

For example, as shown in FIG. 1, the stereoscopic image display apparatus includes a display panel 10 and a parallax barrier 20.

The parallax barrier 20 is disposed in such a manner that the light intercepting portion 21 and the light transmitting portion 22 are alternately arranged and the parallax barrier 20 is disposed on the front surface of the display panel 10.

The display panel 10 includes a right eye image pixel 11 for providing an image on the right eye and a left eye image pixel 12 for providing an image on the left eye.

Therefore, the viewer sees the image displayed on the display panel 10 through the light transmitting portion 22 of the barrier 20. Even though the left and right eyes pass through the same light transmitting portion 22, .

That is, the viewer can see a different image displayed on the left eye image pixel and the right eye image pixel through the light transmission part 22 by the left eye and the right eye, respectively.

On the other hand, in the case of two views in which the light shielding portion 21 and the light transmission portion 22 of the parallax barrier 20 are alternately arranged in a stripe form as shown in FIG. 2, The widths of the light transmitting portions 22 are equal to each other.

When the ratio of the width of the light transmitting portion 22 to the width of the light blocking portion 21 is 1: N-1, N means the time point. When the time is 2, the width of the light blocking portion 21, The ratio of the width of the first electrode 22 to the width of the second electrode 22 becomes 1: 1.

However, if the ratio of the width of the light transmitting portion 22 to the width of the light blocking portion 21 is increased to three or more points exceeding 1: 2, the total area of the light transmitting portion 22 is relatively more than the light blocking portion 21 And the resolution is rapidly lowered.

In addition, if the light transmitting portion 22 corresponding to the slit is vertically formed, there is a problem that the stereoscopic image is rapidly changed when the viewer moves to the left and right, resulting in eye sickness or anger.

3 and 4, a display panel driving unit 200, a 2D display panel 300, and a 3D barrier 400 are provided, and a 3D barrier 400, The light transmitting portion 410 of the light blocking portion 420 and the light transmitting portion 410 of the light blocking portion 420 are formed in diagonal directions.

However, when the light transmitting portion 410 is formed in the obliquely extended oblique direction as in the prior art, only one red pixel R, green pixel G and blue pixel B are exposed, there is a problem that the degree of suppression of generation of a dead zone is insufficient.

The dead zone causes the eyes to sick or dizziness when the viewer moves to the left or right and the right image enters the left eye and the left image enters the right eye, which causes the visibility of the dead zone to deteriorate.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide various information in a 2D image and a 3D image at the same time so that information can be effectively transmitted in 2D and 3D, respectively, And to provide a digital information display device capable of simultaneously realizing 2D and 3D with improved visibility by minimizing a dead zone using a 3D barrier.

To this end, a digital information display device capable of simultaneously implementing 2D and 3D according to the present invention includes a video panel in which a 2D image is displayed, in which red pixels, green pixels, and blue pixels are arranged in the vertical direction; And a 3D barrier disposed on a portion of the image panel, the 3D barrier comprising a slit through which light is transmitted and the pixels are exposed, and a light blocking portion excluding the slit, wherein the slit of the 3D barrier includes a red pixel, And a blue pixel are sequentially exposed. The inclination of the slit formed in the oblique direction is such that the red pixel constituting the three primary colors and the red pixel constituting the three primary colors are formed in the diagonal line direction, And the remaining pixels are each formed at an angle at which one is exposed.

At this time, the slit formed in the oblique direction includes one red pixel, one pixel of the first color among the green pixel and the blue pixel, two pixels of the second color, one pixel of the third color, The first pixel of the second color, the second pixel of the second color, the second pixel of the third color, and the pixel of the first color.

It is preferable that the slits formed in the oblique direction are formed to be deviated from each other for each portion corresponding to each pixel, and have a concavo-convex shape.

It is preferable that the interface between the slit and the light shielding portion is formed in a slanting shape or a slanting shape inclined to one side with respect to a vertical line and inclined to the other side.

In addition, a backlight module is disposed at a rear portion of the image panel, and the backlight module is further provided with more backlight so as to provide more light to the portion where the 3D barrier is installed.

In addition, the 3D barrier is a transparent LCD type barrier, and the transparent LCD type barrier operates only when a 3D image is included in the image displayed on the image panel. In the backlight module, more It is preferable to provide light.

Hereinafter, a digital information display device capable of simultaneously implementing 2D and 3D according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

5, the digital information display device capable of simultaneously implementing 2D and 3D according to the present invention includes a video panel 110 for displaying a two-dimensional image and a part of a front portion of the video panel 110 (Not shown).

When the image panel 110 is an image display device requiring a backlight such as a liquid crystal display (LCD) or an LED display, the backlight module 130 may be disposed on the rear surface thereof.

At this time, the 3D barrier 120 has a size covering only a part of the entire area of the image panel 110, and is disposed at a specific position. A portion other than the 3D barrier 120 is used as a two-dimensional image display area or a two-dimensional text area.

Information provided through a digital information display (DID) is suitable for a three-dimensional image, two-dimensional image is suitable, and text is suitable.

In particular, when text is provided in three dimensions, a phenomenon such as eye pain occurs. Therefore, a two-dimensional area is separately provided and various information is displayed in text thereon.

The backlight driver 142 controls the driving of the backlight module 130 and the barrier driver 143 drives the 3D barrier 120. [ . The control unit 144 controls them.

6A, a 3D barrier 120 having a viewpoint of 8 is illustrated.

The number of viewpoints is defined as 'N' when the ratio of the width of the slit 121, which is the light transmitting portion, to the width of the light blocking portion 122 is 1: N-1. If the number of viewpoints is 8, the width ratio is 1: 7.

That is, when the width W of the sub-pixel 111 and the slit 121 are equal to each other, there is one slit 121 per 8 sub-pixels 111.

At this time, the image panel 110 displays various 2D images including an LCD, a PDP, an OLED, and the like by using sub pixels 111 composed of red pixels R, green pixels G and blue pixels B And constitute one dot.

The red pixel R, the green pixel G, and the blue pixel B are arranged in the vertical direction in the image panel 110. That is, the red pixels R are arranged continuously along the R column direction, and the remaining G columns and B columns are also the same.

The 3D barrier 120 is disposed on a part of the image panel 110 as shown in FIG. 5 and includes a slit 121 and a slit 121, through which light is transmitted and each sub-pixel R / G / And a light blocking portion 122 excluding the light blocking portion 122.

Accordingly, the viewer sees an image displayed on the image panel 110 through the slit 121 of the 3D barrier 120. Even if the left and right eyes pass through the same slit 121, the viewer sees another region of the image panel 110 do.

That is, the left eye and the right eye view the different images displayed on the left eye image pixel and the right eye image pixel through the slit 121, respectively, so that a three-dimensional image can be felt.

Particularly, the slit 121 of the 3D barrier 120 is formed in a diagonal line direction so that the red pixel R, the green pixel G, and the blue pixel B are sequentially exposed.

The inclination of the slit 121 is such that two red pixels R constituting the three primary colors and one green pixel G and one blue pixel B are exposed and one of the remaining pixels is exposed .

For example, if there is only one red pixel R in one dot consisting of a red pixel R and a green pixel G and a blue pixel B, there are two green pixels G, Becomes one.

As described above, according to the present invention, the slit 121 is formed in a straight line shape to provide a natural stereoscopic image even when the viewer moves left and right.

In addition, by setting any one of the RGB primary colors to two, the pixel is emphasized and the dead zone in which the left and right images are reversed with high resolution is reduced to increase the visibility.

The slit 121 further includes a red pixel R, one pixel of the first color among the green pixel G and the blue pixel B, two pixels of the second color, and one pixel of the third color Pixel, a second pixel of the first color, one pixel of the second color, two pixels of the third color, and one pixel of the first color.

For example, if we look at the subpixels 111 sequentially represented by the number '1' in the first slit 121 of FIG. 6A, one green pixel G, two red pixels R, ), Two green pixels (G), one red pixel (R), and two blue pixels (B) are exposed along the oblique direction.

That is, the subpixel 111 is exposed in the order of GRRBGGRBB and the like, and the first four are GRRB, so that R of R / G / B is two, and the fourth to sixth are BGGR, . At this time, the fourth B is used to overlap the R / G / B three primary colors before and after the B color.

Accordingly, any one of the green pixel (G), the red pixel (R) and the blue pixel (B) is emphasized for each dot of the three primary colors to give a rich color feeling, .

Hereinafter, the 3D barrier according to the second embodiment of the present invention will be described.

6B, in the 3D barrier 120 according to the second embodiment of the present invention, the first slit 121a is formed in an oblique direction, and the interface between the second slit 121a and the light blocking portion 122 is diagonal And thirdly, a step is formed between the slits corresponding to each subpixel 111. In this case,

That is, in FIG. 6A, the boundary between the slit 121 and the light intercepting portion 122 is linear, whereas the boundary between the slit 121a and the light intercepting portion 122 is diagonal in FIG. 6B have.

According to this structure, the slit 121a itself is formed in an oblique direction as a whole, and the interface between the slit 121a and the light blocking portion 122 is also oblique. Therefore, even if the viewer moves left and right and views the 3D stereoscopic image, the change of the visible subpixel 111 is smoothly performed and more subpixels 111 are seen.

Therefore, since the stereoscopic image does not change abruptly but is dullly changed, it is possible to provide a stereoscopic image having high resolution and low occurrence of dead zones as well as prevention of eye pain, and good stereoscopic effect.

Hereinafter, a 3D barrier according to a third embodiment of the present invention will be described.

As shown in FIG. 7A, the third embodiment of the present invention is applied to the image panel 110 in which the subpixel 111a has a gull shape (also referred to as a zigzag shape). The gull-shaped sub-pixel 111a can further enhance the image visibility as is known.

The reason for the gull shape in this field is that one sub-pixel 111a is inclined to one side with respect to the vertical line and then tilted to the other side.

At this time, the slit 121a of the 3D barrier 120 is formed in the oblique direction as a whole, and the slit 121a of the oblique line is formed to be a combination of one green pixel (G), two red pixels (R) Tilt and the like are adjusted (usually adjusted according to pixels of the image panel manufactured).

In particular, the subpixel 111a is exposed in the order of GRRBGGRBB and the like. The first four are GRRBs, and two of R / G / B are R, and the fourth to sixth are BGGR, resulting in two of R / G / B. The fourth B is used over and over the R / G / B three primary colors before and after.

Accordingly, any one of the green pixel (G), the red pixel (R) and the blue pixel (B) is emphasized for each dot of the three primary colors to give a rich color feeling, .

Second, the interface between the slit 121a and the light blocking portion 122 also has an oblique shape. If the slit itself is formed in an oblique direction and the boundary surface between the slit 121a and the light intercepting portion 122 is also formed in an oblique shape, even if the viewer moves to the left or right, the change of the visible subpixel is gentle, The exposure area of the sub-pixel 111a becomes larger.

Therefore, since the stereoscopic image does not change suddenly and changes dynamically when moving to the left and right, eye pain is prevented, and a stereoscopic image having high resolution and low occurrence of dead zones is provided.

Third, a step is provided between the slits of the portion corresponding to each sub-pixel 111a to form a concave-convex shape. 7B, a step is formed between the first slit part P1 and the second slit part P2, and a step is provided such that the second slit part P2 protrudes to the left. The third slit portion P3 is stepped to the right between the second slit portion P2 and the third slit portion P3. Further, the fourth slit part P4 is stepped between the third slit part P3 and the fourth slit part P4 so as to protrude to the left again.

That is, according to the present invention, the slit portions are formed to have a shape of 'convex-concave' by giving a step so that the slits alternately protrude left and right. By forming the slits in such a concavo-convex shape, the exposure area of each sub-pixel 111a through the slit 121a can be significantly increased when the sub-pixel 111a is exposed by the RGGB arrangement. As the subpixel exposure area increases, the resolution also increases.

Hereinafter, a 3D barrier according to a fourth embodiment of the present invention will be described.

As shown in FIG. 8, the fourth embodiment of the present invention uses a video panel 110 in which the subpixel 111a has a gull shape.

In the 3D barrier 120, the slit 121b is arranged in the first oblique direction, the second slit in the portion corresponding to each subpixel 111a is stepped, and the third slit 121b and the light blocking portion 122 Has a gull shape corresponding to the gull-shaped sub-pixel 111a.

If the interface between the slit 121a and the light intercepting portion 122 has a gull shape similar to that of the sub-pixel 111a, there is a problem that the degree of continuity between sub-pixels is somewhat lowered, There is an advantage that the exposure area of the sub-pixel 111a through the sub-pixel 111a is maximized.

Hereinafter, a digital information display device capable of simultaneously implementing 2D and 3D with the above configuration will be described.

5, the backlight module 130 is disposed at the rear of the image panel 110 when the image panel 110 is a backlight driving type other than an internal light emission type such as an LCD. A greater number of backlights are disposed so that the backlight module 130 provides more light to the portion where the 3D barrier 120 is installed.

That is, the portion to which the 3D barrier 120 is attached is provided with more backlight than other 2D regions or 2D text regions. Further, the backlight driver 142 controls the backlight of the 2D image portion and the 3D image portion, respectively, by separately controlling these areas. And also controls a plurality of backlights of the 3D image portion.

In addition, the 3D barrier 120 is a transparent LCD type barrier 120, and the transparent LCD type barrier 120 operates only when a 3D image is included in the image displayed on the image panel 110. [ At this time, more light is provided to the portion where the 3D barrier 120 is installed in the backlight module 130.

The control unit 144 analyzes the header file of the inputted image to see if there is a 3D image, and when there is no 3D image, it blocks the gate and base electrode of the transparent LCD type barrier 120 and functions as a simple transparent glass substrate .

In this case, the 2D image is displayed through the entire image panel 110, and not only the backlights of the portion where the 3D barrier 120 is installed are turned on, but only a specific number of backlights are turned on so as to have the same brightness as the other 2D regions.

On the other hand, if it is confirmed that the 3D image exists, the barrier driver 143 drives the 3D barrier 120 to display the 3D image through the 3D barrier 120. At this time, the backlight driver 142 lights up all of the backlights of the portion where the 3D barrier 120 is present, so that the brightness is maximized.

As described above, as the viewpoint increases to 3 or more, the amount of light is greatly blocked by the light intercepting portion 122, so that the quality of the 3D image becomes dark. Therefore, when the 3D image is displayed, the backlight is turned on more than the normal case.

The specific embodiments of the present invention have been described above. It is to be understood, however, that the scope and spirit of the present invention is not limited to these specific embodiments, and that various modifications and changes may be made without departing from the spirit of the present invention. If you have, you will understand.

Therefore, it should be understood that the above-described embodiments are provided so that those skilled in the art can fully understand the scope of the present invention. Therefore, it should be understood that the embodiments are to be considered in all respects as illustrative and not restrictive, The invention is only defined by the scope of the claims.
