BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image realization system capable of two-dimensional and three-dimensional realization, and more particularly, to a multi-image realization system including a liquid crystal display and minimizing a crosstalk area in realizing a three-dimensional image.

Based on the high speed of information built on the high-speed information network today, it has evolved from simply 'listening and talking communication' to the present 'looking and listening multimedia communication' like the telephone of the past, and ultimately 'seeing and feeling' beyond time and space Enjoying 3D stereo communication.

In general, three-dimensional image representing three-dimensional image is based on the principle of stereo vision through two eyes, binocular disparity caused by the parallax of two eyes, that is, the distance between two eyes that are about 65mm apart is the most important It can be called a factor. In other words, when the left and right eyes of the human body see two-dimensional images associated with each other, when these two images are transmitted to the brain through the retina, the brain fuses them to reproduce the depth and the reality of the original three-dimensional image. It is called stereography.

In this regard, a technology for displaying three-dimensional stereoscopic images on a two-dimensional screen using the above-described capability has been introduced. Specifically, a stereoscopic image display, a glasses-free stereoscopic image display, and a holographic display using special glasses are introduced. Can be mentioned.

It is composed of

Accordingly, the polarization directions of the left eye image and the right eye image are different from each other by the patterned retarder 20, and the polarized glasses 30 separate and transmit the left eye image and the right eye image so that the viewer can watch a 3D stereoscopic image. .

Meanwhile, in the 3D stereoscopic image display device, a crosstalk area in which the left eye image and the right eye image overlap with each other is generated. When the viewer's eyes are located in the crosstalk area, the image is blurred and the viewer Will feel dizzy.

Accordingly, a black stripe (not shown) is formed in the patterned retarder 20 to minimize the cross talk area, but this improves the efficiency of the process and the process cost of the patterned retarder 20. , Causing the problem of increasing the thickness of the patterned retarder 20.

Alternatively, a method of widening a black matrix (not shown) between the left eye image and the right eye image of the display device 10 has been proposed, but this lowers the aperture ratio of the provided 3D stereoscopic image, and the viewer The color and brightness are changed depending on the position of the will cause problems.

Accordingly, the present invention has been made to solve the above problems, the first object of the three-dimensional image display device for displaying two-dimensional and three-dimensional stereoscopic image, to minimize the cross-talk area and at the same time improve the aperture ratio .

In this case, the liquid crystal display device has a first polarizing plate attached to one surface, and a second polarizing plate is attached to the other surface on the opposite side to which the first polarizing plate is attached, and the first and second polarizing plates have transmission axes perpendicular to each other. The third pattern has an optical axis perpendicular to the transmission axis of the second polarizing plate.

The first pattern has a transmission axis of 45 degrees, the second pattern has a transmission axis of -45 degrees, and the third pattern has a vertical or horizontal transmission axis.

In this case, the first pattern converts light emitted from the pixel area for the odd-numbered pixel lines into a first polarization state, and the second pattern converts light emitted from the pixel area for the even-numbered pixel lines into a second polarization state. Converted to a state, the patterned retarder further includes a TAC layer and a protective film for protecting the TAC layer.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

FIG. 2 illustrates a multiple image implementation system according to an embodiment of the present invention, which is a diagram of a three-dimensional stereoscopic image.

As shown, the multi-image realization system 100 according to an exemplary embodiment of the present invention includes a display device 110 displaying a large image and a patterned retarder 200 attached to an outer surface of the display device 110. The polarizing glasses 130 selectively transmit an image passing through the patterned retarder 200 from the display device 110.

 In detail, the display device 110 includes a cathode ray tube (CRT), a plasma display panel (PDP), a liquid crystal display device (LCD), and an organic light emitting display device (organic). As one of the electro-luminescence device (OLED), the liquid crystal display device which is most widely used in the present invention will be described as an example.

That is, the liquid crystal display 110 includes an array substrate 111, a color filter substrate 121, and a liquid crystal layer (not shown) interposed between the two substrates 111 and 121, and the two substrates 111 and 121. The first and second polarizing plates 129a and 129b are attached to each outer surface of the s, and a backlight unit is included outside the first polarizing plate 129a although not shown in the drawing.

The first and second polarizing plates 129a and 129b are formed such that the transmission axes perpendicularly cross each other.

Under the premise that the array substrate 111 is an active matrix method, a plurality of gate lines 113 and data lines 115 intersect each other to define a pixel region P, and a thin film transistor Tr is provided at each crossing point. And one-to-one correspondence with the transparent pixel electrode 117 formed in each pixel region P. FIG.

In addition, the inner surface of the color filter substrate 121 may be a color filter (125) of red (R), green (G), and blue (B) color as an example corresponding to each pixel area P, and each of them. A black matrix 123 covering the non-display elements such as the gate line 113, the data line 115, and the thin film transistor Tr is provided. Further, transparent common electrodes (not shown) are provided to cover them.

In this case, the transparent common electrode (not shown) formed on the front surface of the color filter substrate 121 may be formed in each pixel area P of the array substrate 111 according to the mode of the liquid crystal display device 110.

In this case, the pixel electrode 117 and the common electrode (not shown) have a bar phenomenon and have a structure alternately arranged alternately.

On the other hand, the patterned retarder 200 positioned on the outer surface of the color filter substrate 121 is formed from the pixel region P corresponding to the pixel region P positioned in the odd pixel line defined in the horizontal direction. The light emitted through the second polarizing plate 129b becomes a right circularly polarized state, and serves to make the left circularly polarized state corresponding to the pixel region P positioned in the even-numbered pixel line.

To this end, the patterned retarder 200 is a combination of materials that change the phase value internally, that is, a non-refractive element each composed of a retarder, and alternately in different directions for each pixel region P line. It is patterned to have.

That is, the right circular polarization first pattern 210 is formed to correspond to the pixel region P located in the odd pixel line, and the left circular polarization second pattern to correspond to the pixel region P located in the even pixel line. The pattern 220 is formed.

The optical axes of the first and second patterns 210 and 220 are perpendicular to each other.

In this case, the patterned retarder 200 may be formed such that the odd-numbered pixel lines are left circularly polarized and the even-numbered pixel lines are right circularly polarized.

Therefore, according to the configuration of the liquid crystal display device 110 of the present invention described above, light in a right circularly polarized state is emitted from the pixel region P positioned in the odd pixel line, and the pixel positioned in the even pixel line. From the region P, light in a left circularly polarized state is emitted.

In particular, the patterned retarder 200 according to the embodiment of the present invention is characterized in that the light blocking pattern 230 is further formed between the first and second patterns 210 and 220.

That is, the pixel line between the first pattern 210 corresponding to the pixel region P located in the odd pixel line and the second pattern 220 corresponding to the pixel region P located in the even pixel line. The light blocking pattern 230 is formed corresponding to the boundary portion of the light blocking pattern 230.

The light blocking pattern 230 according to the embodiment of the present invention replaces the role of the black matrix 123 formed thickly on the existing black stripe (not shown) and the color filter substrate 121, and thus the left eye image and the left eye image. The crosstalk area in which the right eye images overlap with each other can be minimized, thereby preventing the viewer from feeling dizzy by the crosstalk area.

In addition, by separately forming a black stripe (not shown) on the existing patterned retarder 200, the problem of reducing the efficiency of the process of the patterned retarder 200 and improving the process cost can be solved.

In particular, it is possible to prevent the thickness of the patterned litter 200 from increasing, thereby providing a lightweight and thin display device which is recently required.

In addition, since the black matrix 123 is not required to be widened between the left eye image and the right eye image of the color filter substrate 121, the aperture ratio of the 3D stereoscopic image can be prevented from being lowered. Problems such as changes in brightness can also be prevented. We will discuss this in more detail later.

In this case, the left eye image signal incident to the user's left eye is included in the pixel area P positioned in the odd-numbered pixel line of the liquid crystal display device 110, and the pixel area P positioned in the even-numbered pixel line of the liquid crystal display device 110. By applying an image signal for the right eye incident to the right eye, a display device for realizing a 3D image is realized.

In addition, the polarizing glasses 130 for viewing 3D images forming one set with the liquid crystal display device 110 are characterized in that the polarizing films 131 and 133 are attached to ordinary glasses made of a transparent glass material.

In this case, a first polarizing film 131 for selectively transmitting only right circularly polarized light is attached to the left eye lens corresponding to the left eye of the user when worn, and a second polarizing film for selectively transmitting only left circularly polarized light to the right eye lens. 133 is attached.

Therefore, the user wears the polarizing glasses 130 having such a configuration, and the left eye image and the right eye image data are alternately applied for each pixel line of the liquid crystal display device 110 to pass light having different circularly polarized states. When viewing an image through the patterned retarder 200, the left eye image is incident through the left eye lens of the polarizing glasses 130, and the right eye image is incident through the right eye lens. The three-dimensional stereoscopic image can be viewed.

As an example, in the polarizing glasses 130, the first polarizing film 131 selectively transmits only the right circularly polarized light to the left eye lens, and the second polarizing film 133 selectively transmitting only the left circularly polarized light to the right eye lens. Although it is shown that this is attached, the first and second polarizing films 131 and 133 may be attached to be replaced with each other.

The multi-image realization system 100 according to an embodiment of the present invention may also implement a 2D image in addition to the full size 3D stereoscopic image.

3 is a cross-sectional view schematically showing the structure of a patterned retarder according to an embodiment of the present invention.

As shown, the patterned retarder 200 is substantially attached to the left eye image and the right eye image in order to attach the liquid crystal display (110 of FIG. 2), that is, the second polarizing plate (129b of FIG. 2). The retarder pattern layer 200a for changing the polarization direction is attached to the first adhesive layer 240a.

In this case, the retarder pattern layer 200a is formed by patterning the retarder on the first adhesive layer 240a, and the patterned retarder 200 is formed through the first adhesive layer 240a. 2 is attached to the outside of the second polarizing plate (129b of FIG. 2).

The first protective film 250a for protecting the first adhesive layer 240a is attached to the other surface of the first adhesive layer 240a adhered to the retarder pattern layer 200a, and the first protective film 250a is attached to the retarder pattern layer 200a. Subsequently, the patterned retarder 200 is removed in the step of attaching the patterned retarder 200 to the liquid crystal display (110 of FIG. 2).

In this case, the retarder pattern layer 200a corresponds to the pixel line defined in the horizontal direction of the liquid crystal display device 110 (in FIG. 2), and corresponds to the pixel area (P in FIG. 2) positioned in the odd pixel line. The first pattern 210 for polarization is formed, and the second pattern 220 for left circularly polarized light is formed to correspond to the pixel region (P in FIG. 2) positioned in the even-numbered pixel line.

The optical axes of the first and second patterns 210 and 220 are orthogonal to each other such that the light passing through the patterned retarder 200 is in a right circular polarization state through the first pattern 210 and the second pattern 220. ) To be left circularly polarized.

In particular, the patterned retarder 200 of the present invention forms a light blocking pattern 230 between the first and second patterns 210 and 220, thereby minimizing cross-talk area. Can be.

In addition, a triacetylcellulose (TAC) layer 260 is attached to the upper part of the retarder pattern layer 200a through the second adhesive layer 240b in order to prevent scattering of light emitted from the liquid crystal display device 110 (see FIG. 2). The second protective film 250b for protecting the TAC layer 260 is attached to the upper portion of the TAC layer 260.

Therefore, the light that has been linearly polarized after passing through the liquid crystal display (110 of FIG. 2) and the second polarizing plate (129b of FIG. 2) passes through the patterned litter 200, and then passes through the patterned litter 200. The light finally exiting the patterned retarder 200 by the second pattern 220 may have different circularly polarized states.

Each circularly polarized light is separated into two left and right eyes through polarized glasses (130 of FIG. 2), which are then synthesized in the brain and perceived as a three-dimensional image.

Through this, the user can watch a three-dimensional stereoscopic image.

In particular, the patterned retarder 200 according to the present invention forms a black stripe (not shown) separately on the existing patterned retarder, thereby lowering the efficiency of the patterned retarder process and improving the process cost. I can eliminate it.

In particular, it is possible to prevent the thickness of the patterned litter 200 from increasing, thereby providing a lightweight and thin display device which is recently required.

That is, the patterned retarder 200 of the present invention includes a first protective film 250a and a first adhesive layer 240a, a retarder pattern layer 200a, a TAC layer 260 and a second protective film 250b. The retarder pattern layer 200a and the TAC layer 260 may be formed of a second adhesive layer 240b for adhering to each other, but the patterned retarder including the existing black stripe (not shown) may be the first protective film. And a third adhesive layer for attaching the black stripe layer and the black stripe layer to the retarder pattern layer on the first adhesive layer, the retarder pattern layer, the TAC layer, the second protective film, and the second adhesive layer. .

Accordingly, the patterned retarder 200 of the present invention can significantly reduce the thickness of the patterned retarder 200 compared to the conventional patterned retarder including the black stripe (not shown).

In addition, since the black matrix (121 of FIG. 2) does not have to be formed wide between the left eye image and the right eye image of the color filter substrate (121 of FIG. 2), the aperture ratio of the 3D stereoscopic image can be prevented from being lowered. Problems such as color and brightness may vary depending on the position of.

As described above, the above-described effect is possible by forming the light blocking pattern 230 between the first and second patterns 210 and 220, and the light blocking pattern 230 may be used to form the first and second patterns 210 and 220. The first and second patterns 210 and 220 may be overlapped with each other, or may be formed by patterning a third pattern having a different optical axis from the first and second patterns 210 and 220. This will be described in more detail with reference to the drawings below.

4A to 4C are plan views schematically showing a method of forming a patterned retarder according to the first embodiment of the present invention, and FIG. 5 is a schematic view of FIG.

As illustrated, the light blocking pattern 230 overlaps the first and second patterns 210 and 220 so that the region in which the first and second patterns 210 and 220 overlap each other is the light blocking pattern 230. ) Can be used.

That is, as shown in FIG. 4A, the first pattern region 210a on which the first pattern 210 is to be formed is formed on the other surface of the adhesive layer (240a of FIG. 3) to which the first protective film 250a of FIG. 3 is attached. After defining the second pattern region 220a on which the second pattern 220 is to be formed and the light blocking region 230a on which the light blocking pattern 230 is to be formed, the first pattern region 210a is illustrated in FIG. 4B. ) And the first pattern 210 in the light blocking region 230a.

In this case, the first pattern area 210a is an area corresponding to the pixel area (P in FIG. 2) positioned in the odd-numbered pixel line defined in the horizontal direction of the liquid crystal display (110 in FIG. 2). 230a is an area corresponding to the boundary of each pixel line, and the first pattern 210 has a transmission axis having an angle of 45 degrees.

Next, as shown in FIG. 4C, the second pattern 220 is patterned on the adhesive layer (240a of FIG. 3) on which the first pattern 210 is patterned, and the second pattern 220 is the first pattern. It is formed in the second pattern region 220a and the light blocking region 230a, which are regions other than the first pattern region 210a in which the 210 is formed.

In this case, the second pattern area 220a is an area corresponding to the pixel area (P in FIG. 2) positioned in the even-numbered pixel line defined in the horizontal direction of the liquid crystal display device 110 (in FIG. 2). 220 is a transmission axis having an angle of −45 degrees perpendicular to the transmission axis of the first pattern 210.

At this time, since the first pattern 210 and the second pattern 220 are formed to overlap each other in the light blocking region 230a, the region where the first and second patterns 210 and 220 overlap each other is 45 degrees. The transmission axis having the angle of transmission and the transmission axis having the angle of −45 degrees are formed to overlap each other, and the pattern formed by overlapping the first and second patterns 210 and 220 in the region 230a thereof is the light blocking pattern 230. It will be.

That is, as shown in FIG. 5, the patterned first pattern 210 except for the second pattern region 220a and the patterned second pattern 220 except for the first pattern region 210a overlap each other. In addition, the patterned retarder 200 having the light blocking pattern 230 formed between the first and second patterns 210 and 220 is completed.

6 is a plan view schematically showing a patterned retarder according to a second embodiment of the present invention.

As shown in the drawing, the patterned retarder 200 has a first region in a region corresponding to the pixel region (P in FIG. 2) positioned in an odd-numbered pixel line defined in the horizontal direction of the liquid crystal display (110 in FIG. 2). The pattern 210 is formed, and the second pattern 220 is formed in a region corresponding to the pixel region (P in FIG. 2) positioned in the even-numbered pixel line.

The first and second patterns 210 and 220 have transmission axes that are perpendicular to each other, and are alternately positioned. That is, the first pattern 210 is formed of a transmission axis having an angle of 45 degrees, and the second pattern 220 is formed of a transmission axis having an angle of −45 degrees orthogonal to the transmission axis of the first pattern 210.

In particular, a light blocking pattern is formed between the first and second patterns 210 and 220. The light blocking pattern according to the second embodiment of the present invention is different from the first and second patterns 210 and 220. A third pattern 230 having an optical axis is formed.

In this case, the optical axis of the third pattern 230 is formed to have a transmission axis perpendicular to the transmission axis of the second polarizing plate (129b of FIG. 2) of the liquid crystal display (110 of FIG. 2) to which the patterned retarder 200 is to be attached. do.

That is, when the transmission axis of the second polarizing plate (129b of FIG. 2) attached to the outside of the color filter substrate (121 of FIG. 2) of the liquid crystal display device 110 of FIG. 2 is vertically formed, the patterned retarder ( The optical axis of the third pattern 230 of 200 is formed to be perpendicular to the transmission axis of the second polarizing plate (129b of FIG. 2).

Accordingly, the linearly polarized light that has passed through the second polarizing plate (129b of FIG. 2) is blocked and absorbed by the third pattern 230 so that light is blocked through the region where the third pattern 230 is formed.

That is, in the patterned retarder 200 according to the second embodiment of the present invention, the third pattern 230 becomes a light blocking pattern.

7A to 7C are plan views schematically illustrating a method of forming a patterned retarder according to a second embodiment of the present invention.

As shown in FIG. 7A, the second pattern area 220a on which the second pattern 220 (FIG. 6) is to be formed on the other surface of the adhesive layer (240a of FIG. 3) to which the first protective film 250a of FIG. 3 is attached. After defining the third pattern region 230a in which the third pattern (230 of FIG. 6) is to be formed, the first pattern 210 is patterned in an area except for the second and third pattern regions 220a and 230a. .

In this case, the first pattern area 210a is an area corresponding to the pixel area (P in FIG. 2) positioned in the odd pixel line defined in the horizontal direction of the liquid crystal display device 110 (in FIG. 2). 210 consists of a transmission axis with an angle of 45 degrees.

Next, as shown in FIG. 7B, the second pattern 220 is patterned on the adhesive layer (240a of FIG. 3) on which the first pattern 210 is patterned, and the second pattern 220 is the first pattern. It is formed in the second pattern region 220a except for the region where the 210 is formed and the region where the third pattern 230 (in FIG. 6) is to be formed.

In this case, the second pattern area 220a is an area corresponding to the pixel area (P in FIG. 2) positioned in the even-numbered pixel line defined in the horizontal direction of the liquid crystal display device 110 (in FIG. 2). 220 is a transmission axis having an angle of −45 degrees perpendicular to the transmission axis of the first pattern 210.

Next, as shown in FIG. 7C, the third pattern 230 is formed in the third pattern region 230a except for the region in which the first and second patterns 210 and 220 are formed.

In this case, the third pattern 230 is positioned between the first and second pattern regions 210a and 220a, and the third pattern 230 is a liquid crystal display device to which the patterned retarder 200 is to be attached. It is formed to have a transmission axis perpendicular to the transmission axis of the second polarizing plate (129b of FIG. 2).

Therefore, since the third pattern 230 blocks the light passing through the second polarizing plate (129b of FIG. 2), and becomes the light blocking pattern, the light blocking pattern between the first and second patterns 210 and 220 may be reduced. The patterned retarder 200 in which the 230 is formed is completed.

Meanwhile, the light blocking pattern 230 of the present invention is equal to or smaller than the width of the black matrix (123 of FIG. 2) formed on the color filter substrate (121 of FIG. 2) of the liquid crystal display (110 of FIG. 2). It is preferable to form to have.

If the width of the light blocking pattern 230 is formed to be wider than that of the black matrix (123 in FIG. 2), the aperture ratio of the 3D stereoscopic image is lowered as pointed out in the problem of the prior art, and the color is varied depending on the position of the viewer. This is because it causes problems such as a change in brightness and brightness.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.
