The present invention relates to a three-dimensional image display device having a pivot function, and more particularly, has a pivot function that operates in a landscape mode and a portrait display mode by rotation of the display device. The present invention relates to a display device capable of realizing a stable three-dimensional image in both display modes.

The technology of realizing 3D image that allows you to feel 3D depth and 3D feeling from 2D image is widely used in aerospace, art industry, automobile business as well as home appliance and communication industry as well as direct related fields such as display. The technical ripple effect is expected to be higher than the current high definition television (HDTV).

The most important factor for the human sense of depth and three-dimensionality is binocular disparity due to the distance between the two eyes, but there is also a deep relationship between psychological and memory factors. On the basis of whether a 3D image can be provided to a user, it is generally classified into a volumetric type (volumetric type), a 3D type (holographic type), and a stereoscopic type (stereoscopic type).

The volume expression method is a way to feel the perspective of the depth direction due to psychological factors and inhalation effects. The viewing angle is calculated by a 3D computer graphic or an observer who displays perspective, superposition, shadow, contrast, and movement by calculation. It is applied to so-called IMAX movies, which provide a large large screen and cause optical illusions to be sucked into the space.

The three-dimensional representation method known as the most complete stereoscopic image implementation technology can be represented by laser light reproduction holography to white light reproduction holography.

In addition, the stereoscopic expression method uses a physiological factor of both eyes to make a stereoscopic feeling. Specifically, a plane-related image of parallax information is included in left and right eyes of a human being approximately 65 mm apart. In this case, the brain generates spatial information before and after the display surface in the process of fusing them, and uses stereographic ability (stereoography). This stereoscopic expression method is called a multi-eye display method, and the spectacle method using the special glasses on the observer's side or the parallax barrier, lenticular or integral on the display side depending on the actual stereoscopic generation position. It can be divided into an autostereoscopic method using a lens array of the back.

In detail, the principle of realizing a three-dimensional image of an autostereoscopic three-dimensional image display apparatus using a parallax barrier or a lens array includes a stripe between a display panel and a user that simultaneously display stereo images for left and right eyes. As an example, an image display apparatus using a barrier is described as an example in which a slit and a barrier are formed or a plurality of semi-cylindrical lenticular lenses are arranged so that an observer feels a three-dimensional effect. do.

1 is a plan view for explaining an operation of a parallax barrier type image display apparatus.

As shown in FIG. 1, the parallax barrier type video display device 10 includes a display panel 20 and a parallax barrier 30 that simultaneously display left and right images.

The display panel 20 alternately defines a left eye pixel L displaying a left eye image and a right eye pixel R displaying a right eye image, and the parallax barrier 30 includes a display panel 20 and a user ( 40) is placed between. In the parallax barrier 30, the slit 32 and the barrier 34 selectively passing light from the left and right pixels L and R, respectively, are repeatedly arranged in a stripe shape facing the user 40 in the vertical direction. It is.

Accordingly, the left eye image I _L displayed on the left eye pixel L of the display panel 20 reaches the left eye of the user 40 via the slit 32 of the parallax barrier 30 and the display panel 20. Right eye image (I _R ) displayed on right eye pixel (R) of) reaches the right eye of user 40 via slit 32 of parallax barrier 30, at which time left / right eye images I _L , I _R ) contains separate images considering a parallax that can be detected by a human, and the user 40 combines the two images to recognize a three-dimensional image.

At this time, the width P of the left and right eye pixels L and R formed in the display panel 20, the width P1 of the slit 32 of the parallax barrier 30, and the barrier of the parallax barrier 30 The following relation holds between the width P2 of (34) and the width E of the left and right eyes.

P1 + P2 = 2 / (1 / E + 1 / P)

As mentioned above, the left / right eye spacing E is about 65 mm, and thus, the width P of the left / right eye pixels L and R using the value of the left / right eye spacing E and the above relational expression. By designing the width P1 of the slit 32 and the width P2 of the barrier 34, a parallax barrier type 3D image display device and a 3D image may be realized.

Meanwhile, in line with the rapidly evolving informatization era, the utilization of the display device also appears in various ways. As an example, one screen can be rotated vertically or horizontally so that it can be appropriately used for each purpose. One product was introduced, which is currently used for display screens and monitors for mobile phones.

In other words, conventional display devices have generally been fixed to display only one of a landscape image having a width in a horizontal direction greater than a height in a vertical direction or a portrait image on the contrary. A video display device having a pivot function for displaying a horizontal image or a vertical image as needed by rotating the image is being researched. In the case of a movie, such a video display device has a landscape display mode. In the case of the operation of displaying a large amount of information, for example, in the case of working by opening a large number of text files, it is utilized to operate in a portrait display mode.

However, the method of providing the horizontal image and the vertical image by the rotation of the display device is not considered to be suitable for the three-dimensional image display of the Pararex barrier or the lens array method, which will be described with reference to the drawings.

2 is a view showing an image display state during rotation of an autostereoscopic 3D image display device having a pivot function.

As shown in FIG. 2, the image display device 50 has a pivot function that is operated in a landscape display mode and a portrait display mode by rotating 90 °.

When the image display device 50 operates in the horizontal display mode, the display panel provides a left eye image I _L and a right eye image I _R to the user to display a three-dimensional image. The two images are synthesized to recognize the 3D image.

However, when the image display device 50 operates in the vertical display mode, the left eye image I _L and the right eye image I _R are not provided at the left and right views, but are provided at the time divided up and down. Accordingly, the same image is provided in the left and right eyes of the user so that the 3D image cannot be recognized.

That is, in the parallax barrier method or the lens array method due to the binocular disparity of the left and right eyes spaced apart in the horizontal direction, the slit, the barrier or the lens is formed long along the vertical direction. Since a long line is arranged along the direction, and thus the viewpoint is formed up and down, a problem in that a correct 3D image cannot be realized.

Accordingly, the present invention has been made to solve the above problems, to provide a video display device that can realize a stable three-dimensional image in both the horizontal display mode and the vertical display mode by the rotation of the user or display device. There is this.

In order to achieve the above object, the present invention provides a display panel including a plurality of pixels to which a plurality of image data are input; And a viewpoint generating unit which separates the plurality of image data from each other and displays the images from a plurality of viewpoints, and includes a plurality of transmission portions inclined with respect to a horizontal direction defined in a horizontal direction when viewed from the front of the display panel.

Provide a device.

Each of the plurality of pixels may have a square shape, and four adjacent pixels among the plurality of pixels form one unit pixel displaying red, green, blue, and white colors.

The distance E between the plurality of viewpoints is greater than 0 mm and less than or equal to 65 mm in both the horizontal display mode and the vertical display mode. Horizontal image data is input to the plurality of pixels in the horizontal display mode, and the vertical display is performed. In the mode, the vertical image data different from the horizontal image data is input.

The plurality of pixels are divided into the first to ninth pixels, and the plurality of viewpoints are first to ninth viewpoints, and the first to third viewpoints are respectively displayed in the horizontal display mode. And image data input to the fifth, seventh, ninth, second, fourth, sixth, and eighth pixels, and the first to ninth views in the vertical display mode, respectively.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the drawings.

3 is a view for explaining a three-dimensional image display state in the image display apparatus according to an embodiment of the present invention.

As shown in FIG. 3, the 3D image display apparatus 110 according to an exemplary embodiment of the present invention has a pivot function operable in a landscape display mode or a portrait display mode. Has

First, when operating in a horizontal display mode for displaying a long horizontal image, the 3D image display device 110 displays a horizontal left eye image IL _L and a horizontal right eye image IL _{R separated} accordingly. The user recognizes the 3D horizontal image by synthesizing the horizontal left eye image IL _L and the horizontal right eye image IL _{R which} are respectively introduced into the left and right eyes.

When the 3D image display device 110 operates in a vertical display mode in which a long image is displayed by rotating the 3D image display device 110 by 90 °, the 3D image display device 110 may include a vertical left eye image IP _L separated from left and right. The vertical right image (IP _R ) is displayed, and the user recognizes the 3D vertical image by synthesizing the vertical left image (IP _L ) and the vertical right image (IP _R ) coming into the left and right eyes, respectively.

That is, the 3D image display apparatus 110 according to the present invention displays left and right eye images separated left and right in both the horizontal display mode and the vertical display mode, thereby making the 3D image comfortable in both the horizontal display mode and the vertical display mode. Can be displayed.

To this end, the 3D image display apparatus 110 includes a viewpoint generating unit that separates the viewpoint into left and right and up and down, and the image data and the image data input to the 3D image display apparatus 110 in the horizontal display mode and the vertical display mode. The input methods are different from each other.

That is, the 3D image display apparatus 110 divides the viewpoint into up, down, left, and right, and in the horizontal display mode, the left and right divided viewpoints are input to the left and right eyes of the user, respectively, and the 3D image display apparatus 110 is not used. On the other hand, in the vertical display mode, the left and right divided viewpoints used in the horizontal display mode are disposed up and down, and the vertically divided viewpoints, which are not used in the horizontal display mode, are arranged left and right, respectively, and are inputted into the left and right sides of the vehicle. 3D image is recognized.

Therefore, the viewpoints used in the horizontal display mode and the vertical display mode are different from each other, and in each mode, image data for a 3D image should be input at the viewpoints used.

4 is a cross-sectional view of a three-dimensional image display device according to an embodiment of the present invention.

As shown in FIG. 4, the 3D image display apparatus 110 according to an exemplary embodiment of the present invention includes a display panel 120 and a viewpoint generating unit 130, and a user displays an image displayed on the display panel 120. This is recognized through the viewpoint generating unit 130.

The display panel 120 includes a plurality of pixels for displaying a 3D image, and the images displayed on the plurality of pixels are divided into a plurality of viewpoints by the viewpoint generating unit 130 and displayed.

The user sees the separately displayed image separately from the two eyes and combines them to recognize the three-dimensional image.

In particular, the three-dimensional image display device 110 according to an embodiment of the present invention, the occurrence of the inverted three-dimensional image generated by inverting the left and right eyes of the image displayed by the horizontally separated and alternately repeated views are generated A multi-view method is used to minimize and allow a large number of users to comfortably watch 3D images.

That is, when two viewpoints are used, the left eye image must be input to the left eye and the right eye image must be input to the right eye to synthesize normal 3D images. There is an inverted stereoscopic system in which the right eye is input and the right eye image is input to the left eye. In this inverted stereoscopic, normal 3D image synthesis is impossible.

Therefore, the 3D image display device 110 according to the embodiment of the present invention minimizes the occurrence of inverted stereoscopic by generating a plurality of viewpoints.

In the multi-view three-dimensional image display device 110, the view point generation unit 130 is composed of a plurality of blocking portions and a plurality of transmission portions, and the left and right eye images are clearly separated to produce a three-dimensional image with a sense of depth. Design the width of each of the plurality of transmission parts as small as possible to express.

Therefore, instead of the width of the blocking and transmissive portions of the viewpoint generating unit 130, the intervals or pitches of the pixels of the display panel 120, the distance S between the display panel 120 and the viewpoint generating unit 130, and the viewpoint The multi-view 3D image display device 110 is formed in consideration of the distance D between the generator 130 and the user and the distance E between the viewpoints, and the relationship between them is represented by Equation (1). Is the same as

E = PD / S ------ (1)

Here, the distance between the left and right eyes of the user is approximately 65 mm, and when an adjacent viewpoint is generated below 65 mm, different images of different viewpoints may be input into the left and right eyes of the user, so that the distance E between the viewpoints in Equation (1) is 65 mm or less. The distance between the display panel 120 and the pitch P of the pixels of the display panel 120, the distance S between the display panel 120 and the view generator 130, the view generator 130, and the user The distance D can be determined.

In addition, the 3D image display apparatus 110 according to an exemplary embodiment of the present invention has a pivot function that operates in a landscape display mode and a portrait display mode so that the 3D image display apparatus 110 may operate. Displays a stable three-dimensional image even when rotated by 90 ㅀ.

That is, the 3D image display apparatus 110 generates a viewpoint divided into up, down, left, and right sides (or vertically and vertically), and for this purpose, the plurality of transmission units and the plurality of blocking units of the viewpoint generating unit 130 are horizontally and vertically viewed when viewed from the front. It is formed to be inclined with respect to this will be described with reference to the drawings.

5A and 5B are plan views in a landscape display mode and a portrait display mode, respectively, of a three-dimensional image display device according to an embodiment of the present invention, and FIG. 6 is an embodiment of the present invention. It is a perspective view for explaining the multi-view of the three-dimensional image display device.

5A and 5B, the 3D image display apparatus 110 according to an exemplary embodiment of the present invention includes a display panel 120 and a viewpoint generating unit 130, and the display panel 120 includes a plurality of display panels 120. The viewpoint generating unit 130 includes a plurality of transmission units 130a and a plurality of blocking units 130b.

5A and 5B, a plurality of transmissive portions 130a are shown by solid lines. The plurality of transmissive portions 130a actually have a predetermined width and pass image data displayed on a plurality of pixels.

On the other hand, the plurality of blocking units 130b represent the remaining areas outside the solid line, and block the image data displayed on the plurality of pixels.

A flat panel display (FPD) may be used as the display panel 120. Specifically, a liquid crystal display (LCD), a field emission display (FED), a plasma image display apparatus may be used. (PDP: Plasma Display Panel), EL (Electroluminescent Display) and the like can be used.

In addition, the viewpoint generating unit 130 may use a parallax barrier or a lens array. In particular, when the display panel 120 is a transmissive flat panel display panel including a backlight assembly and a liquid crystal display panel, the viewpoint generating unit 130 may include a liquid crystal. The display panel 120 may be disposed between the front surface of the display panel or between the backlight assembly and the liquid crystal display panel, and the display panel 120 is a light emitting flat panel display panel such as an electroluminescent display, a plasma image display, or an electroluminescent display. The viewpoint generating unit 130 is disposed on the front surface of the light emitting flat panel display panel.

For example, the plurality of pixels of the display panel 120 may be classified into nine types, and different image data may be input to the first to ninth pixels P1 to P9, respectively, as shown in FIG. 6. The images displayed by the plurality of pixels P1 to P9 are displayed at the first to ninth views (views 1 to 9) which are different views by the viewpoint generating unit 130.

The number of types of pixels into which different image data is input and the number of generated viewpoints may be variously determined according to the use of the 3D image display device according to an exemplary embodiment of the present invention. Here, for convenience, nine pixel types and nine The viewpoint will be described as an example.

Each of the first to ninth pixels P1 to P9 of the display panel 120 has a square shape having substantially the same widths as the first and second widths W1 and W2 in the horizontal and vertical directions, and four adjacent pixels It may be arranged to form one unit pixel indicating red, green, blue, and white (R, G, B, W).

For example, the first, third, second, and ninth pixels P1, P3, P2, and P9 adjacent to each other may display red, green, blue, and white (R, G, B, W) Green, blue, and white (R, G, B, and W) of the fifth, seventh, sixth, and fourth pixels P5, P7, P6, One unit pixel can be formed.

In the horizontal display mode, since the first width W1 is parallel to the horizontal direction, the first width W1 becomes the pitch P of the pixel in Equation (1), whereas in the vertical display mode, the first width W1 is parallel to the horizontal direction. Since W2 is parallel to the horizontal direction, the second width W2 becomes the pitch P of the pixel in equation (1).

However, since the first width and the second width W1 and W2 are substantially the same, the remaining design elements are displayed such that the distance E between the viewpoints of Equation (1) is greater than 0 mm and less than 65 mm regardless of the display mode. Pitch P of the pixel of the panel 120 (in this case, the first width W1 or the second width W2), the distance S between the display panel 120 and the viewpoint generating unit 130, and the viewpoint generating unit ( The 3D image display apparatus may be formed by determining the distance D between the 130 and the user.

Although not shown in the drawings, in another embodiment of the present invention, the pixels of the display panel may have a rectangular shape having a long side. In this case, the pitch of the pixel of the rectangular long side or short side of the formula (1) may vary depending on the display mode. P) will play a role.

In this case, the pitch P of the pixel is changed in the horizontal display mode and the vertical display mode, and the distance E between the viewpoints is proportional to the pitch P of the pixel according to Equation (1).

That is, when the distance E between the viewpoints when the long side of the pixel serves as the pitch P of the pixel of the equation (1) serves as the pitch P of the pixel of the short side expression (1) of the pixel It has a value larger than the distance E between the viewpoints.

Therefore, in order for the 3D image display device according to another embodiment of the present invention to display a 3D image normally in both the horizontal display mode and the vertical display mode, the long side of the pixel serves as the pitch P of the pixel of Equation (1). In this case, the long side serving as the pitch P of the pixels of the display panel, the remaining design elements, and the distance S between the display panel and the viewpoint generating unit such that the distance E between the viewpoints is greater than 0 mm and less than about 65 mm. The distance D between the viewpoint generator and the user may be determined.

In this case, it will be understood that the distance E between the viewpoints when the short side of the pixel serves as the pitch P of the pixel of Equation (1) is also larger than 0 mm and about 65 mm or less.

On the other hand, the plurality of transmission unit 130a of the viewpoint generating unit 130 is formed to be inclined with respect to the horizontal direction when viewed from the front, so that the viewpoint in the horizontal display mode and the vertical display mode in both the vertical and horizontal (vertical and vertical) direction Create separate.

5A and 5B illustrate an example in which the inclination angles of the plurality of transmission parts 130a are arctan (1/2) with respect to the horizontal line in the vertical display mode. The inclination angles of the plurality of transmission parts 130a are three-dimensional images. It may be variously determined according to the use of the display device.

In the horizontal display mode, the first, third, fifth, seventh, ninth, second, fourth, sixth, and eighth pixels are sequentially disposed at the first to ninth viewpoints (view1 to view9) separated from right to left. Images of (P1, P3, P5, P7, P9, P2, P4, P6, and P8) are displayed, and the first, second, third, fourth, Images of the fifth, sixth, seventh, eighth, and ninth pixels P1, P2, P3, P4, P5, P6, P7, P8, and P9 are displayed.

The user recognizes the three-dimensional image by synthesizing the different images displayed at these points separately from the left and right sides.

FIG. 6 illustrates the arrangement of the first to ninth viewpoints (views 1 to 9) and the image displayed at the corresponding viewpoints in the horizontal display mode, which the 3D image display apparatus 110 (FIGS. 5A and 5B) is intended to display. If the image is a cube and a sphere placed in front of it, the image displayed at the first and ninth views (view1 and view9) is the same as the image recognized when viewed from different angles when the actual cube and sphere are arranged. .

That is, each of the first to ninth views (views 1 to 9) may be referred to as nine different camera views. In this case, the user may recognize the image as a 3D image by receiving images from various angles.

On the other hand, as mentioned above, the arrangement order of the pixels corresponding to the images displayed at a plurality of viewpoints in the horizontal display mode and the vertical display mode is different, and according to the arrangement order of the pixels corresponding to the viewpoints, The input can display a normal 3D image.

That is, in order to display the 3D image in the horizontal display mode, the first, third, fifth, seventh, ninth, second, fourth, sixth, and eighth pixels (P1, P3, P5, P7, P9, P2, P4, P6, and P8) must be sequentially inputted in sequence. If the image data is applied to the vertical display mode as it is, non-contiguous image data is input at a plurality of points of time, and a normal three-dimensional image is inputted. It is not displayed.

Therefore, in the horizontal display mode, the first, third, fifth, seventh, ninth, second, fourth, sixth, and eighth pixels P1, P3, P5, P7, P9, P2, P4, P6, and P8 Consecutive horizontal image data is input to the 3D image in order, and in the vertical display mode, the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth pixels are displayed. Continuous vertical image data is input to (P1, P2, P3, P4, P5, P6, P7, P8, P9) in order to display a three-dimensional image. And a data converting unit converting the data and the vertical image data into the first through ninth pixels P1 through P9.

For example, in the horizontal display mode, the first, third, fifth, seventh, ninth, second, fourth, sixth, and eighth pixels P1, P3, P5, P7, P9, P2, P4, If data1, data2, data3, data4, data5, data6, data7, data8, data9 are sequentially input to P6, P8) to display a three-dimensional image corresponding to the horizontal image data, the first, second, Third, fourth, fifth, sixth, seventh, eighth, and ninth pixels (P1, P2, P3, P4, P5, P6, P7, P8, P9) in sequence data1, data2, data3, data4 , data5, data6, data7, data8, and data9 may be input to display a 3D image corresponding to the vertical image data.
