Description

3D image display device {3D image displayable device}

The present invention relates to a three-dimensional image display device, and more particularly to a three-dimensional image display device that can implement a high-quality three-dimensional image by preventing crosstalk problems.

In general, a liquid crystal display device is composed of two opposite electrodes and a liquid crystal layer formed therebetween. The liquid crystal molecules of the liquid crystal layer are driven by an electric field generated by applying a voltage to the two electrodes. Liquid crystal molecules have polarization property and optical anisotropy. Polarization property means that when liquid crystal molecules are placed in an electric field, charges in the liquid crystal molecules are attracted to both sides of the liquid crystal molecules, and the direction of molecular arrangement changes according to the electric field. Refers to changing the path or polarization state of the emitted light differently according to the incident direction or the polarization state of the incident light due to the elongated structure of the liquid crystal molecules and the aforementioned molecular arrangement direction.

Accordingly, the liquid crystal layer may exhibit a difference in transmittance due to voltages applied to the two electrodes, and display the 2D image by changing the difference for each pixel.

Meanwhile, in recent years, liquid crystal display devices capable of three-dimensional display have been developed in response to increasing user demand for liquid crystal display devices capable of displaying a more realistic image having three-dimensional properties.

In general, stereoscopic images expressing 3D are made by the principle of stereo vision through two eyes, using the parallax of two eyes, that is, binocular disparity which appears because the eyes are about 65 mm apart. A liquid crystal display device capable of displaying a stereoscopic image has been proposed.

In more detail, 3D implementations show that the left and right eyes looking at the liquid crystal display see different 2D images, and when these two images are transmitted through the retina to the brain, the brain correctly fuses them together to produce the original 3D image. Depth and realism are reproduced. This phenomenon is commonly referred to as stereography.

Techniques for displaying 3D stereoscopic images in a device having a 2D screen display such as a liquid crystal display device include a stereoscopic image display by a special glasses, an autostereoscopic stereoscopic display, and a holographic display method.

For example, the autostereoscopic 3D display method may include a parallax barrier method that separates and observes an image through a vertical grid-shaped aperture in front of each image corresponding to the left and right eyes, A semicylindrical lens may be divided into a lenticular method using a lenticular plate having a stripe arrangement and an integral photography method using a fly's eye lens plate.

In addition, the stereoscopic image display method using the special glasses can be largely divided into a shutter glass method and a patterned retarder method. The shutter glass method separates left and right eye images by matching response speeds of the panel and glasses. Meanwhile, the patterned retarder method separates left and right eye images by using patterned retarders having different polarization states for each pixel line.

1 is a diagram illustrating a conventional three-dimensional image display device of the patterned retarder method.

As shown in the drawing, the conventional three-dimensional image display device 10 includes a liquid crystal display device 20 for displaying an image, a patterned retarder 30 attached to an outer surface of the liquid crystal display device 20, and The glasses 40 are configured to selectively transmit an image passing through the liquid crystal display device 20 through the patterned retarder 30.

First, the liquid crystal display device 20 includes an array substrate 21, a color filter substrate 22, and a liquid crystal layer interposed between the array substrate 21 and the color filter substrate 22. And first and second polarizers 23 and 24 attached to outer surfaces of the array substrate 21 and the color filter substrate 22, respectively. The said 1st and 2nd polarizing plates 23 and 24 are comprised so that the polarization axis may mutually perpendicularly cross. Although not shown in the figure, the outer surface of the first polarizing plate 23 is configured to include a backlight unit (not shown).

The array substrate 21 is connected to the gate and data lines 25 and 26 and the gate and data lines 25 and 26 that define a plurality of pixel regions P to cross each other and to each pixel region P. Correspondingly, a thin film transistor Tr is provided. In addition, the pixel electrode 27 is connected to the thin film transistor Tr.

The color filter substrate 22 includes a black matrix 28 corresponding to a boundary of each pixel region P, and a color filter layer 29 including red, green, and blue color filter patterns sequentially corresponding to each pixel region P. FIG. ) And the color filter layer 29 are provided on the front surface of the common electrode (not shown).

On the other hand, the patterned retarder 30 provided on the outer surface of the second polarizing plate 24 attached to the outer surface of the color filter substrate 22 has a pixel area P positioned in the odd pixel line in the horizontal direction. ), The light emitted from the pixel region P through the second polarizing plate 24 is in the right circularly polarized state, and in the left circularly polarized state in the pixel region P located in the even-numbered pixel lines. Subsequently, a material that changes a phase value internally is patterned so as to have a different direction by alternately changing pixel region lines.

Therefore, according to the configuration of the liquid crystal display device 20 described above, light in a right circularly polarized state is emitted from the pixel region P positioned in the odd pixel lines, and the pixel region P positioned in the even pixel lines. ) Is emitted from the left circularly polarized state. In this case, in the liquid crystal display device 20, the left eye image signal incident to the left eye of the user is stored in the pixel area P positioned in the odd pixel line. For example, a 3D image may be realized by applying a right eye image signal incident to the right eye.

On the other hand, the glasses 40 for viewing the 3D image forming a set with the liquid crystal display device 20 having the above-described configuration, a polarizing film is attached to the conventional glasses made of a transparent glass material. In this case, a first polarizing film 42 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 for selectively transmitting only left circularly polarized light to the right eye lens. The polarizing film 44 is attached.

Accordingly, the liquid crystal display device 20 in which the user wears the 3D image glasses 40 having such a configuration, alternately line by line, and displays left and right eye image data and displays images having different circularly polarized states. When viewing an image through the left eye image through the left eye lens and the right eye image through the right eye lens, the user can watch a 3D image by combining these two images.

However, in the conventional 3D image display device, a cross-talk problem occurs in which a left eye image passes through a right eye glasses and a right eye image passes through a left eye glasses. For example, the crosstalk problem may be caused by a misalignment between the patterned retarder 30 and the pixel region P. FIG.

However, even when the patterned retarder 30 and the pixel region P are aligned correctly, crosstalk problems occur because unwanted phase differences occur in the 3D image display device. Referring to FIG. 2, which is a schematic cross-sectional view of a conventional 3D image display device, the conventional 3D image display device 10 includes a second polarizing plate 24 of a liquid crystal display device (20 of FIG. 1) including a liquid crystal layer 60. The patterned retarder 30 is positioned on the surface of the patterned retarder 30, and the surface treated TAC 50 layer 50 for protecting the patterned retarder 30 is stacked on the patterned retarder 30.

However, the surface treatment TAC layer 50 causes unwanted phase difference. The surface treated TAC layer 50 has an in-plane retardation (Rin) of about 1.5 to 2.0 nm and a thickness retardation (Rth) of about 30 to 60 nm. As described above, an unwanted phase difference is generated by the surface treated TAC layer 50 having a large thickness phase difference, thereby causing a crosstalk problem in which the right eye image passes through the left eye glasses or the left eye image passes through the right eye glasses. Doing.

An object of the present invention is to prevent an unwanted phase difference or compensate for an unwanted phase difference in a 3D image display device.

Accordingly, by solving the crosstalk problem of passing the left eye glasses or the left eye images through the right eye glasses, a high quality 3D image is provided.

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

3 is a diagram illustrating a three-dimensional image display device according to a first embodiment of the present invention.

As shown, the 3D image display device 100 according to the first embodiment of the present invention includes a liquid crystal display device 110 for displaying an image and a patterned surface attached to an outer surface of the liquid crystal display device 110. The retarder 140, the surface treatment layer 150 attached to the outside of the patterned retarder 140, the liquid crystal display device 110, and the patterned retarder 140 and the surface treatment layer 150. Eyeglasses 160, characterized in that selectively transmit the image passing through the).

First, the liquid crystal display 110 includes an array substrate 120, a color filter substrate 130, and a liquid crystal layer interposed between the array substrate 120 and the color filter substrate 130. And first and second polarizers 112 and 114 attached to outer surfaces of the array substrate 120 and the color filter substrate 130, respectively. The array substrate 120, the color filter substrate 130, and the liquid crystal layer form a liquid crystal panel. The first and second polarization axes of the first and second polarizers 112 and 114 are vertically intersected with each other. Although not shown in the drawings, a backlight unit (not shown) is included on the outer surface of the first polarizing plate 112.

The array substrate 120 is connected to the gate and data lines 122 and 124 and the gate and data lines 122 and 124 that define a plurality of pixel regions P to cross each other and to each pixel region P. Correspondingly, a thin film transistor Tr is provided. In addition, the pixel electrode 126 is connected to the thin film transistor Tr.

The color filter substrate 130 includes a black matrix 132 corresponding to the boundary of each pixel region P, and a color filter layer 134 including red, green, and blue color filter patterns sequentially corresponding to each pixel region P. FIG. ) And a color filter layer 134 and a common electrode (not shown) are provided on the front surface.

In this case, the common electrode (not shown) provided on the front surface of the color filter substrate 130 may be alternately arranged with the pixel electrode 126 in each pixel region P according to the mode of the liquid crystal display device 110. It may be formed on the array substrate 120.

On the other hand, the patterned retarder 140 provided on the outer surface of the second polarizing plate 114 attached to the outer surface of the color filter substrate 130 is a pixel area (P) located in the odd pixel line in the horizontal direction. In this case, the light emitted from the pixel region P through the second polarizing plate 114 is in the right circular polarization state, and in the left pixel polarization state in the pixel region P positioned in the even-numbered pixel line. Subsequently, a material that changes a phase value internally is patterned so as to have a different direction by alternately changing pixel region lines. In this case, the patterned retarder 140 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, due to the configuration of the liquid crystal display device 110 described above, light in a right circularly polarized state is emitted from the pixel region P positioned in the odd pixel lines, and the pixel region P positioned in the even pixel lines. ) Is emitted from the left circularly polarized state. In this case, the pixel area P in the odd-numbered pixel line of the liquid crystal display device 110 receives a left-eye image signal incident to the left eye of the user to the pixel region P in the even-numbered pixel line. For example, a 3D image may be realized by applying a right eye image signal incident to the right eye.

The three-dimensional image display device 100 of the present invention includes a surface treatment layer 150, the surface treatment layer 150 is made of a material having a very small phase difference. In particular, by using a material having a very small thickness retardation (Rth), it is intended to prevent unwanted retardation caused by the surface treatment layer.

Specifically, the surface treatment layer 150 is made of a polymer material having both in-plane retardation (Rin) and thickness retardation (Rth) values of about 10 nm or less. That is, instead of the conventional surface treated TAC layer (50 in FIG. 2), a polymer material having a small thickness retardation value is used. For example, a cyclo-olefin polymer (COP), a cyclo-olefin copolymer (COC), polyethylene naphtalate (PEN), or the like may be used. These materials have a transmittance of 90% or more and a coefficient of thermal expansion of 80% or less, which is suitable for surface treatment layers.

On the other hand, the glasses 160 for viewing 3D image forming one set with the liquid crystal display device 110 having the above-described configuration, a polarizing film is attached to the conventional glasses made of a transparent glass material. In this case, a first polarizing film 162 selectively attaching 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 second lens selectively transmitting only left circularly polarized light to the right eye lens. The polarizing film 164 is attached.

Therefore, the user wears the 3D image glasses 160 having such a configuration, and the liquid crystal display 110 for displaying images having different circularly polarized states with different left and right eye image data applied alternately line by line. When viewing an image through the left eye image through the left eye lens and the right eye image through the right eye lens, the user can watch a 3D image by combining these two images.

In the above 3D image display device, the light incident from the backlight unit (not shown) includes a liquid crystal display device 110 including a first polarizing plate 112 and a second polarizing plate 114, and a patterned retarder ( 140 and the surface treatment layer 150, and finally through the glasses 160 to reach the user's eyes. At this time, in the conventional display device, since the surface-treated TAC layer (50 in FIG. 2) has a relatively large thickness retardation, crosstalk problems occur in which the right eye image passes through the left eye glasses or the left eye image passes through the right eye glasses. In the 3D image display device of the present invention, since the surface treatment layer 150 is made of a polymer material having a relatively small thickness retardation, an unwanted retardation may be minimized to prevent a crosstalk problem.

4 is a schematic cross-sectional view of a 3D image display device according to a first embodiment of the present invention.

As shown, the 3D image display device 100 according to the first embodiment of the present invention includes an array substrate 120 and a color filter substrate 130 facing each other through the liquid crystal layer 170, and the array. A liquid crystal display including a substrate 120 and first and second polarizers 112 and 114 attached to the outside of the color filter substrate 130 and a backlight unit (not shown) under the first polarizer 112. The device 110, the patterned retarder 140 positioned on the second polarizing plate 114, the surface treated TAC layer 150 and the surface treated layer positioned on the patterned retarder 140. 150 consists of glasses 160 located in front of.

Of the light incident from the backlight unit, only light parallel to the first polarization axis passes through the first polarizing plate 112, and after passing through the liquid crystal layer 170, only light parallel to the second polarization axis is passed through the second polarizing plate. It passes through 114 to reach the patterned retarder 140.

The light passing through the patterned retarder 140 passes through the odd-numbered pixel lines of the patterned retarder 140 to become a right-circular polarization state and passes through the even-numbered pixel lines of the patterned retarder 140. The left circularly polarized state is obtained. Thereafter, the surface-treated TAC layer 150 passes through, and the surface-treated TAC layer 150 of the present invention has an in-plane retardation (Rin) and a thickness retardation (Rth) of about 10 nm or less. Characterized by being made of a polymeric material, the phase difference generation is minimized. Accordingly, the light in the right circularly polarized state passing through the odd-numbered pixel lines of the patterned retarder 140 and the light in the left circularly polarized state passing through the even-numbered pixel lines of the patterned retarder 140 may reflect the polarization state. The glasses 160 are reached as they are.

Thereafter, the light in the right circularly polarized state passes through the first polarizing film 162 of the glasses 160 to reach the left eye, and the light in the left circularly polarized light forms the second polarizing film 164 of the glasses 160. Pass through to reach the right eye.

In the present invention, since the phase difference change is minimized by the surface treatment layer 150, the crosstalk problem in which the right eye image passes through the left eye glasses or the left eye image passes through the right eye glasses by the phase difference change is prevented and high quality 3 It is possible to provide a dimensional image.

5 is a diagram illustrating a 3D image display device according to a second embodiment of the present invention, and FIG. 6 is a schematic cross-sectional view of the 3D image display device according to a second embodiment of the present invention.

As shown, the 3D image display device 200 according to the first embodiment of the present invention includes a liquid crystal display 210 for displaying an image and a patterned surface attached to an outer surface of the liquid crystal display 210. The retarder 240, the surface treated TAC layer 250 attached to the outside of the patterned retarder 240, the liquid crystal display device 210, and the patterned retarder 240 and the surface treated TAC layer. The spectacles 260 are configured to compensate for the phase difference caused by the 250 and selectively transmit an image passing through the surface treatment TAC layer 250.

First, the liquid crystal display device 210 includes an array substrate 220, a color filter substrate 230, and a liquid crystal layer interposed between the array substrate 220 and the color filter substrate 230. And first and second polarizers 212 and 214 attached to outer surfaces of the array substrate 220 and the color filter substrate 230, respectively. The first and second polarization axes of the first and second polarizers 212 and 214 are perpendicularly intersected with each other. Although not shown in the figure, the outer surface of the first polarizing plate 212 is configured to include a backlight unit (not shown).

The array substrate 220 is connected to the gate and data lines 222 and 224 and the gate and data lines 222 and 224 that define a plurality of pixel regions P to cross each other and to each pixel region P. Correspondingly, a thin film transistor Tr is provided. In addition, the pixel electrode 226 is connected to the thin film transistor Tr.

The color filter substrate 230 includes a black matrix 232 corresponding to a boundary of each pixel region P, and a color filter layer 234 formed of red, green, and blue color filter patterns sequentially corresponding to each pixel region P. FIG. ) And the color filter layer 234, and a common electrode (not shown) is provided on the entire surface.

In this case, the common electrode (not shown) provided on the front surface of the color filter substrate 230 may be alternately arranged with the pixel electrode 226 in each pixel region P according to the mode of the liquid crystal display device 210. It may be formed on the array substrate 220.

On the other hand, the patterned retarder 240 provided on the outer surface of the second polarizing plate 214 attached to the outer surface of the color filter substrate 230 is a pixel area (P) positioned in the odd pixel line in the horizontal direction. ), The light emitted from the pixel region P through the second polarizing plate 214 is in the right circularly polarized state, and in the left circularly polarized state in correspondence to the pixel region P located in the even-numbered pixel lines. Subsequently, a material that changes a phase value internally is patterned so as to have a different direction by alternately changing pixel region lines. In this case, it is apparent that the patterned retarder 240 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 210 described above, light in a right circularly polarized state is emitted from the pixel region P positioned in the odd pixel lines, and the pixel region P positioned in the even pixel lines. ) Is emitted from the left circularly polarized state. At this time, in the liquid crystal display device 210, the left eye image signal incident to the left eye of the user is stored in the pixel area P positioned in the odd pixel line. For example, a 3D image may be realized by applying a right eye image signal incident to the right eye.

On the other hand, the surface treatment TAC layer 250 generates an unwanted phase difference. That is, the surface-treated TAC layer 250 has an in-plane retardation (Rin) of about 1.5 to 2.0 nm and a thickness retardation (Rth) value of about 30 to 50 nm, thereby causing an unwanted phase. Change will occur.

In order to solve the problem, according to the present invention, the glasses 260 are attached to the first polarizing film 262 and the first polarizing film 262 to selectively transmit only the right polarized light to the left eye lens. The first phase compensating film 263 includes a second polarizing film 264 for selectively transmitting only left circularly polarized light and a second phase compensating film attached to the second piece of film 264. 265 is configured.

The first phase compensation film 263 and the second phase compensation film 265 have the same phase difference value as that generated in the surface treatment TAC layer 250 and have opposite phase directions. That is, the unwanted phase change generated by the surface treated TAC layer 250 is canceled by the first and second phase compensation films 265 to reach the first and second polarizing films 262 and 164. The light may have a polarization state immediately after passing through the patterned retarder 240.

In the 3D image display device 200 as described above, only light parallel to the first polarization axis among light incident from a backlight unit (not shown) positioned under the first polarizing plate 212 is applied to the first polarizing plate 212. After passing through the liquid crystal layer 270, only light parallel to the second polarization axis passes through the second polarizing plate 214 to reach the patterned retarder 240.

The light passing through the patterned retarder 240 passes through the odd-numbered pixel lines of the patterned retarder 240 and becomes a right-circular polarization state, and passes through the even-numbered pixel lines of the patterned retarder 240. The left circularly polarized state is obtained. Thereafter, the surface treated TAC layer 250 passes, and since the surface treated TAC layer 250 of the present invention has a large retardation value, light having a left circularly polarized light or a right circularly polarized state is transferred to the surface treated TAC layer 250. While passing through, a phase change by the first magnitude occurs in the first direction.

However, in the present invention, the first light which can compensate for the phase change before the light passing through the surface treatment TAC layer 250 reaches the first and second polarizing films 262 and 264 of the glasses 260. And the second phase compensation films 263 and 265, the phase change caused by the surface treatment TAC layer 250 is canceled out. That is, each of the first and second phase compensation films 263 and 265 generates a phase change by a first magnitude in a second direction opposite to the first direction, thereby allowing the surface treated TAC layer 250 to be used. Cancel the phase change that has occurred.

Therefore, the right and left polarized light immediately after passing through the patterned retarder 240 reaches each of the first and second polarizing films 262 and 264, so that the problem of cross talk does not occur. do.

7 is a simulation result showing crosstalk generation according to a phase difference.

As shown in the figure, when the phase difference value is large, a large number of cross-talks (C / T) are generated. That is, crosstalk occurs in the graphs A, B, and C having a large phase difference value, but crosstalk rarely occurs in the graph D having a small phase difference value.

In the conventional three-dimensional image display device, a large phase difference occurs due to the surface treated TAC layer (50 in FIG. 2), thereby causing a problem of crosstalk. However, in the first embodiment of the present invention, the crosstalk problem caused by the phase difference can be prevented by using the surface treatment layer 150 made of a polymer material having a small phase difference, in particular, a thickness phase difference value. Further, in the second embodiment of the present invention, by attaching the first and second phase compensation films 263 and 265 to the glasses 26 to compensate for the phase change caused by the surface treatment TAC layer 250, This prevents crosstalk problems. Therefore, according to the 3D image display apparatus of the present invention, it is possible to provide a high quality 3D image without a cross talk problem.
