[0001] The present invention relates to a hybrid stereoscopic image display device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 3D image display apparatus, and more particularly to a hybrid 3D image display apparatus to which both a spectacle method and a non-spectacle method can be applied.

2. Description of the Related Art [0002] In recent years, a display device capable of 3D image display has been commercialized in response to an increase in users' demands for a display device capable of realizing a stereoscopic and more realistic image, that is, a 3D image display device.

Generally, stereoscopic images expressing 3D are made by the principle of stereoscopic vision through two eyes. By using the binocular disparity which appears because the time difference of the two eyes, that is, A display device capable of displaying stereoscopic images has been proposed.

A more detailed description of the 3D image implementation is that the left and right eyes looking at the display device each see a different 2D image and when the two images are transmitted to the brain through the retina, The depth and the sense of reality are reproduced. Such a phenomenon is usually referred to as stereography.

Technologies proposed for displaying a 3D image in a device having 2D image display such as a liquid crystal display device include a stereoscopic image display using special glasses, a non-eye stereoscopic image display, and a holographic display method.

In the 3D image display system using the special glasses, the polarizing glasses system using the vibration direction or the rotation direction of the polarized light, the time division spectacle system alternately presenting the right and left images while switching them, and the light of different brightness in the left / Which is the method of concentration difference.

In the case of various 3D image display devices for viewing various 3D images, the special glasses type 3D image display device necessarily requires polarized glasses or time-division glasses, and in the case of the non-eye glasses, it is possible to view 3D images without special glasses However, in order to increase the viewing area of the 3D image, multiple viewports must be implemented. Therefore, when the number of viewports is more than three, that is, the view area is larger than the three view areas,

Meanwhile, in recent years, some users prefer a more excellent 3D image quality due to the user's taste, and some users prefer to watch 3D images without glasses even if the 3D image quality is lowered a little.

In addition, even if the same user wants to watch a 3D image in a non-eyeglass system at some time according to a 3D image source or a state of the day, and at some times, he wants to watch a 3D image in a glasses system.

However, since the 3D image display device currently marketed as a commercial product is differentiated into the spectacles type and the non-spectacles type, the user must select only the 3D image display device adopting any one of the glasses type and the non-spectacles type, The selection of the 3D image display device considering the size of the 3D image display device is small and it is a problem to increase the consumption of the 3D image display device.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hybrid 3D image display device capable of selectively viewing a 3D image of a glasses type and a non-spectacle glasses in consideration of a user's taste.

When the voltage is applied through the first and second electrode layers, the refractive index boundary periodically disappears, And it is possible to realize a 3D image of glasses type.

At this time, the polymer material layer is formed of polymer localized liquid crystal (PLLC), which is a polymer material including liquid crystal molecules.

In addition, a black matrix is formed on the color filter substrate corresponding to the boundary of the pixel lines, and the boundary due to the refractive index difference overlaps with the black matrix located at the boundary of the pixel lines.

The patterned retarder may include a first phase pattern for changing the linearly polarized light into left or right circularly polarized light and a second phase pattern for forming a circularly polarized state opposite to the first phase pattern, And is formed alternately in units of pixel lines.

The hybrid 3D image display device may include a left eye lens and a right eye lens each having a first phase film and a second phase film having an optical axis perpendicular to the first phase film, 1 and a polarizing glass having a second polarizing film. When the hybrid 3D image display device operates in a glasses mode, power is applied to the first and second electrode layers of the variable lens layer, When the first electrode layer and the second electrode layer of the variable lens layer are operated in a non-eyeglass mode, power is not applied to the first and second electrode layers of the variable lens layer, So that the boundary due to the difference in refractive index can be maintained.

In addition, a backlight unit is provided on the outer surface of the first polarizer.

The hybrid 3D image display apparatus according to the present invention has the effect of enlarging the width of the 3D image viewing method by the user because the user can view the 3D image by selecting the polarizing glasses system or the non-glasses system according to his or her preference.

Furthermore, there is an effect of suppressing deterioration of image quality in a non-eyeglass system even when viewing a 2D image instead of viewing the 3D image.

The lenticular lens is formed directly on the inner side or the outer side of the liquid crystal panel instead of using a separate substrate, thereby realizing a light and shade tolerance compared to a conventional non-eye-tightening 3D image display device in which a separate lenticular plate is attached, The 3D image quality of the non-eyeglass system can be improved.

At this time, the polarizing glasses 145 are required when viewing a 3D image by a spectacle method, and are not required when the hybrid 3D image display device 101 is driven in a non-spectacle mode.

The liquid crystal display device 110 includes a liquid crystal panel 112 including an array substrate 115 and a color filter substrate 120 and a liquid crystal layer 170 interposed between the two substrates 115 and 120, First and second polarizers 125 and 130 attached to the outer surface of the liquid crystal panel 112 and a backlight unit (not shown) on the outer surface of the first polarizer 125 .

In this case, the pixel electrode and the common electrode alternating in each pixel region P form a bar shape, and the liquid crystal panel 112 having such a structure is formed between the adjacent pixel electrodes and the common electrode As shown in Fig.

In another modification, the common electrode may be formed in a form having a bar-shaped opening corresponding to each pixel region P on the entire display region of the array substrate 115. In this case, The liquid crystal panel having such a configuration is driven by a fringe field generated by a common electrode having a plurality of bar-shaped openings and pixel electrodes positioned on upper and lower sides.

For convenience of explanation, a plurality of pixel regions P connected to the same gate line 116 among a plurality of pixel regions P included in the liquid crystal panel 112 are defined as pixel lines OL and EL In an embodiment of the present invention, a video signal applied to the left eye of the user for realizing a 3D image among the plurality of pixel lines OL and EL is represented through an odd-numbered pixel line OL, And the video signal is expressed through the even-numbered pixel line EL.

At this time, a black matrix 121 is provided between neighboring pixel lines OL and EL to form a boundary between the pixel lines OL and EL.

On the other hand, in the hybrid 3D image display apparatus according to the embodiment of the present invention, the odd-numbered pixel line OL describes the left eye image, the even-numbered pixel line EL displays the right eye image, It is obvious that the OL pixel OL can display the right eye image and the even pixel line EL can display the left eye image.

The first and second polarizers 125 and 130 are arranged on the outer surface of the liquid crystal panel 112 so that the transmissive axes of the liquid crystal panels 112 are perpendicular to each other. A backlight unit (not shown) is provided on the outer surface of the polarizer 125 to form a liquid crystal display device 110. The first polarizer plate 125 is attached to the outer surface of the array substrate 115 with a first transmission axis and the second polarizer plate 130 is attached to the outer surface of the color filter substrate 120, 1 with a second transmission axis perpendicular to the transmission axis.

The patterned retarder 140 is provided on the outer surface of the second polarizer 130 of the liquid crystal display device 110.

The pattern reliader 140 provided on the outer surface of the second polarizer 125 may be arranged in the horizontal direction from the pixel regions P corresponding to the pixel regions P located in the odd- In order to make the light emitted through the second polarizer 130 to be a right circularly polarized light state and to have a left circularly polarized state corresponding to the pixel region P located in the even-numbered pixel line EL, And a first and a second phase patterns (hereinafter, referred to as " first and second phase patterns ") having different orientations alternately for each pixel line OL and EL provided on the liquid crystal panel, (141a, 141b) are provided.

In this case, the pattern reliader 140 that causes incident light to be a left circularly polarized light or a right circularly polarized light is characterized by, for example, developing a? / 4 phase difference, and further, And the optical axis of the retarder 140 is +45 degrees and -45 degrees with respect to the second transmission axis of the second polarizer 130 provided in the liquid crystal display device 110, respectively.

On the other hand, the outer surface of the pattern reliader 140 is provided with a variable lens layer 260, which is most characteristic of the hybrid 3D image display apparatus 101 according to the embodiment of the present invention.

At this time, the variable lens layer 260 has a plate shape corresponding to the entire display area of the liquid crystal display device 110 and is formed of a transparent conductive material such as indium-tin-oxide (ITO) or indium-zinc- A polymeric material such as PLLC (Polymerized Polymerized Polymer (PLLC)), which is capable of imparting an orientation to the first electrode layer 213 under specific conditions and capable of changing the position of the liquid crystal molecules by voltage application, a second electrode layer made of a transparent conductive material such as indium-tin-oxide (ITO) or indium-zinc-oxide (IZO) is formed on the polymer material layer 220, 225).

At this time, the polymeric material layer 220 is in the form of a plate having no difference in thickness according to the plane position of the liquid crystal display device 110, but when the voltage is not applied to the polymeric material layer 220, 260) itself has a boundary with a difference in refractive index, and the boundary having the refractive index difference periodically repeats the shape of a lenticular lens, and serves as a lenticular plate composed of a plurality of substantially lenticular lenses Feature.

When a voltage is applied to the polymeric material layer 220, the liquid crystal molecules located inside the polymeric material layer 220 are all arranged in the same direction, so that the polymeric material layer 220 can not function as a lenticular lens. It forms a layer that does not affect the light.

Accordingly, the hybrid 3D image display device 101 according to the embodiment of the present invention includes the polymer material layer 220 having the above-described characteristics and the transparent first and second electrode layers 213 and 225 provided on the lower and upper portions thereof The hybrid 3D display device is optionally a non-eye-tight type or a glasses type depending on whether a voltage is applied or applied to the variable lens layer.

Each of the lens units 250 serving as a plurality of lenticular lenses generated by the difference in refractive index when the voltage is not applied to the polymer material layer 220 in the variable lens layer 260, (OL, EL).

At this time, the boundary of each lens unit 250 is arranged so as to overlap with the black matrix 121 formed on the color filter substrate 120 of the liquid crystal panel 112.

Hereinafter, a method of forming the variable lens layer, which is the most characteristic configuration of the hybrid 3D image display device according to the embodiment of the present invention, will be described in detail.

4A to 4F are cross-sectional views illustrating a method of forming a variable lens layer on the outer surface of a patterned retarder in a hybrid 3D image display device according to an embodiment of the present invention. In this case, in the case of the liquid crystal display device, internal components are omitted, and only the color filter substrate and the second polarizer are shown.

4A, a transparent conductive material such as indium-tin-oxide (ITO) is deposited on a pattern drift layer 140 provided on the outer surface of a second polarizer 130 attached to a liquid crystal panel ITO) or indium-zinc-oxide (IZO) on the entire surface to form a first electrode layer 213.

4B, a polymer material such as PLLC (polymer localized liquid crystal) may be coated on the first electrode layer 213 using a coating device such as a bar coating device, a spin coating device, A polymer material layer 220 is formed by coating using any one of slit coating apparatuses.

4C, a transparent conductive material such as indium-tin-oxide (ITO) or indium-zinc-oxide (IZO) is deposited on the polymeric material layer 220, The second electrode layer 225 is formed.

4D, the polymeric material layer 220 is formed on the second electrode layer 225 in order to align the liquid crystal molecules in the polymeric material layer 220, A voltage is applied to the electrode layer 213 and the second electrode layer 225 so that a voltage difference is applied to the polymer material layer 220 interposed between the first and second electrode layers 213 and 225, .

The first voltage may be about 200V to about 400V so that the liquid crystal molecules in the polymer material layer 220 can be aligned in an initial direction in a short period of time.

Next, as shown in FIGS. 4E and 4F, with respect to the polymer material layer 220 in which the liquid crystal molecules therein are arranged in one direction by applying a first voltage to the polymer material layer 220, A scan type slit mask 290 having a light transmission area TA and a blocking area BA on the second electrode layer 225 and capable of moving in the one direction with the transmission area TA being a slit shape, .

Thereafter, UV light is irradiated on the slit mask 290 and the energy density of the UV light is changed, and the slit mask 290 is moved in one direction to increase the energy density of the polymer material layer 220 A UV slit scanning exposure with a difference is performed.

The UV slit scanning exposure is performed and power is applied to the first and second electrode layers 213 and 225 to have a voltage difference so that the polymeric material layer 220 has a size smaller than the first voltage And a second voltage is applied. At this time, it is preferable that the second voltage has a size within a range of 0V to 180V.

When the UV light and the second voltage having a predetermined energy density are applied to the polymer material layer 220, the positional state of the liquid crystal molecules, which are initially arranged in one direction located in the polymer material layer 220, The tilt angle of the liquid crystal molecules can be changed. When the arrangement position of the liquid crystal molecules is changed according to the position on the plane of the polymer material layer 220, the optical phase of the light passing through the polymer material layer 220 and serves as a lens for refracting the incident light by changing the optical phase.

On the other hand, in order to make the boundary of the refractive index difference form a lenticular shape, a UV light is irradiated at a constant speed from the first first point to the second point located on the straight line at the portion irradiated with the UV light through the slit during the UV slit scanning exposure, When the second voltage applied to the polymer material layer 220 is gradually changed from OV to 150 V in the process of moving the slit mask 290, the arrangement position of the liquid crystal molecules is more precisely tilted The refractive index in the polymer material layer 220 is finally changed.

Therefore, when it is assumed that the portion to which the OV is applied has a first refractive index, the first refractive index is symmetric with respect to the portion to which 0V is applied, and gradually increases or decreases with reference to the first refractive index. So that the change of the refractive index in the cross-sectional shape forms a lenticular lens shape (semi-elliptical shape).

That is, while a slit scan exposure is performed, a voltage of a large magnitude is gradually applied at a voltage of a small magnitude gradually with reference to the boundary of each lens, and then a voltage of a small magnitude is gradually applied again, A voltage of a small magnitude is gradually applied to a large-sized voltage on the basis of a boundary, and then a voltage of a large magnitude is gradually applied to the polymeric material layer 220 to arrange liquid crystal molecules inside the polymeric material layer 220, The change of the refractive index to the phase is to form a lenticular lens shape (semi-elliptical shape) periodically.

When the power is not applied to the first and second electrode layers 213 and 225, the refractive index of the variable lens layer 260 formed in this manufacturing method maintains a semi-elliptical shape at the boundaries of the refractive indexes so that a plurality of lenticular lenses And serves as a lenticular plate provided.

When the voltage is applied to the polymeric material layer 220 by applying power through the first and second electrode layers 213 and 225, the tilt angle of the liquid crystal molecules is changed, The semi-elliptical shape of the refractive index boundary, which causes the change in the index of refraction, is eliminated by virtue of the arrangement, so that the refractive index of the light passing through it is hardly changed.

Therefore, the variable lens layer 260 does not serve as a lenticular plate, so that the light incident on the variable lens layer 260 is transmitted without changing the refractive index.

A description will be given of the behavior of light at the time of viewing a 3D image by a spectacle method and a non-spectacle method of a hybrid 3D image display device according to an embodiment of the present invention having a variable lens layer in more detail.

First, referring to Fig. 2, transmission of light at the time of viewing a 3D image by the spectacles system will be described.

The light emitted from the backlight unit (not shown) of the liquid crystal display device 110 normally passes through the first polarizing plate 125, the liquid crystal panel 112, and the second polarizing plate 130 to be linearly polarized. The linearly polarized light passes through the patterned retarder 140, that is, passes through the first phase pattern 141a of the patterned retarder 140 and forms a left circularly polarized state while the second phase pattern 141b ), It becomes a right circularly polarized state.

Then, the light passes through the pattern reliader 140 and passes through the variable lens layer 260 in the state where the left and right circularly polarized light passes through the variable lens layer 260. At this time, A predetermined voltage is applied to the polymeric material layer 220 through the first and second electrode layers 213 and 225 so that the boundary due to the difference in refractive index disappears in the polymeric material layer 220, Has a refractive index of the same level and thus does not serve as a lenticular plate having a partially different refractive index.

Therefore, the left or right circularly polarized light having passed through the pattern drifter 140 is still left or right circularly polarized and passes through the variable lens layer 260. In the case of the glasses type, The polarizing glasses 145 are used.

The polarizing glasses 145 include a left eye lens 145a and a right eye lens 145b. The left eye lens 145a is provided with a first phase film 152a for generating a phase change of? / 4, A second phase film 152b having a polarizing film 150a and a phase shift of? / 4 and having an optical axis perpendicular to the first phase film 152a is provided in the right eye lens 145b, And a second polarizing film 150b having the same transmission axis as that of the first polarizing film 150a.

Accordingly, the light passing through the patterned retarder 140 and being in a state of left-handed or right-handed circularly polarized light is incident on the left eye or right eye lenses 145a and 145b of the polarizing glasses 145. At this time, (Hereinafter, referred to as a first linearly polarized light state) in the left and right direction, and in this case, coincides with the transmission axis of the first polarizing film 150a, Passes through the left eye lens 145a, and enters the left eye of the user.

However, when the right circularly polarized light is incident on the left circularly polarized light 145a, the second linearly polarized light perpendicular to the first linearly polarized light state becomes perpendicular to the transmission axis of the first polarizing film 150a Is blocked by the first polarizing film 150a, and finally does not pass through the left eye lens 145a, so that it is not incident on the left eye of the user.

On the contrary, the right circularly polarized light of the light passing through the pendant retarder 140 passes through the second phase film 152b for the right eye lens 145b of the polarizing glasses 145, And is incident on the right eye of the user through the right eye lens 145b. However, the left circularly polarized light is incident on the second phase film 152b And is in a state of being perpendicular to the transmission axis of the second polarizing film 150b. Thus, the second polarizing film 150b can not transmit, and therefore, it does not pass through the right eye lens 145b can not do it.

Accordingly, when the hybrid 3D image display apparatus 101 according to the embodiment of the present invention operates in a spectacle mode, the variable lens layer 260 does not cause a change in the refractive index of the lenticular shape, It is possible to view a 3D image that is realized by the polarizing glasses and the pattern drifter 140 like the general glasses type 3D image display device.

3, when a hybrid 3D image display apparatus according to an embodiment of the present invention operates in a non-eyeglass mode without polarizing glasses, light passing through the liquid crystal display device 110 is linearly polarized in one direction And passes through the pattern-driven retarder 140.

At this time, the light having passed through the first and second phase patterns 141a and 141b provided in the patterned retarder 140 is left-circularly polarized or right-circularly polarized.

The left or right circularly polarized light is incident on the variable lens layer 260. Since power is not applied to the first and second electrode layers 213 and 225 in the variable lens layer 260, The material layer 220 has a plurality of periodic lens portions 250 formed by a boundary due to a difference in refractive index.

Therefore, the light incident by the plurality of lens units 250 embodied in the polymer material layer 220 is refracted in a specific direction, and the light is directed to a plurality of view areas determined by the arrangement of the lens unit 250 In this case, the user can view the 3D image by looking at the light emitted through the LCD 110, the patterned retarder 140, and the variable lens layer 260 in the viewable area for 3D viewing.

On the other hand, in the case of the non-spectacle method, when a predetermined voltage is applied to the variable lens layer 260, the variable lens layer 260 does not implement a plurality of periodic lens units (not shown) that cause a change in the refractive index In this case, it is optimized for 2D video viewing, and 2D viewing with excellent 2D quality is also possible compared to a conventional 3D video display device with a fixed lenticular lens.

The hybrid 3D image display apparatus 101 according to the embodiment of the present invention having the above-described configuration includes a polymeric material layer 220 made of PLLC and first and second electrode layers 213 and 225 on the lower and upper portions thereof Since the variable lens layer 260 selectively operates in the spectacles mode or the non-spectacles mode, it is possible to enjoy the 3D viewing preference according to the user's preference, Further, in the case where a lenticular lens is directly formed on the outer surface of the pattern reliader 140 provided on the outer surface of the liquid crystal display device 110 without using a separate substrate, It is possible to improve the 3D image quality of the non-eyeglass type by suppressing the attachment error and the like.
