Description

3D stereoscopic image display system

The present invention relates to a 3D image implementation system, and more particularly, to an image display device having a patterned retarder and a 3D image implementation system having glasses.

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, recently, liquid crystal display devices capable of expressing 3D images have been developed in response to increasing user demand for liquid crystal display devices capable of realizing a 3D image.

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 image implementation, the left and right eyes looking at the liquid crystal display see different 2D images, and when these two images are transmitted to the brain through the retina, the brain accurately fuses each other and the original 3D image. It is to reproduce the sense of depth and the real sense of this phenomenon is commonly called stereography (stereography).

Techniques for displaying 3D stereoscopic images in a device having a 2D image 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 system.

The three-dimensional image display method by the special glasses transmits the polarized glasses method using the vibration direction or the rotation direction of the polarized light, the time-divided glasses method alternately presenting while switching the left and right images, and the light of different brightness in the left and right. It can be divided into concentration difference method.

In addition, the autostereoscopic 3D display method has a parallax barrier method that allows the user to separate and observe the image through a vertical grid-shaped aperture in front of each image corresponding to the left and right eyes, and a semi-cylindrical type. The lens may be divided into a lenticular method using a lenticular plate having a stripe arrangement of a cylindrical lens and an integral photography method using a lens plate shaped like a fly's eye.

Among them, a 3D image display device using special glasses is most commonly used.

1 is a view showing a 3D image implementation system using a conventional special glasses.

As shown in the drawing, the 3D image realization system using the conventional special glasses has a liquid crystal display device 10 displaying a large image and a lambda / 4 patterned retarder attached to an outer surface of the liquid crystal display device 10 ( 40 and spectacles 45 which selectively transmit images passing through the λ / 4 patterned retarder 40 from the liquid crystal display device 10.

First, the liquid crystal display device 10 includes an array substrate 15, a color filter substrate 20, a liquid crystal layer interposed between the two substrates 15 and 20, and the two substrates 15, 20) The first and second polarizing plates 25 and 30 attached to the outer side surfaces of the first and second polarizing plates 25 and 30 are not shown in the figure, but the outer side surfaces of the first polarizing plate 25 include a backlight unit (not shown). In this case, the first and second polarizing plates 25 and 30 are configured such that their transmission axes perpendicularly cross each other.

On the other hand, the λ / 4 patterned retarder 40 provided on the outer surface of the second polarizing plate 30 attached to the outer surface of the color filter substrate 20 is located at an odd pixel line in the horizontal direction. Corresponding to the region P, the light emitted from the pixel region P through the second polarizing plate 30 is in a right circularly polarized state, and left circularly polarized light corresponding to the pixel region P positioned in even-numbered pixel lines. The birefringent material whose phase is internally changed so as to be in a state is patterned so as to alternate with each other for each pixel region P line. The lambda / 4 patterned retarder 40 for causing light to be left circularly polarized or right circularly polarized is characterized in that it has a lambda / 4 phase difference.

In the λ / 4 patterned retarder 40 in which the phase difference of λ / 4 is generated, the optical axis is +45 degrees with respect to the transmission axis of the second polarizing plate 30 provided in the liquid crystal display device 10, respectively. -45 degrees.

Therefore, according to the configuration of the conventional 3D image realization system 1 described above, the liquid crystal display device 10 is positioned in an odd pixel line after passing through the λ / 4 patterned retarder 40. Light in the right circularly polarized state is emitted from the region, and light in the left circularly polarized state is emitted from the pixel region located in the even-numbered pixel line. In this case, the left eye image signal incident to the left eye of the user is applied to the pixel area positioned in the odd pixel line of the liquid crystal display device 10, and the right eye of the pixel area P located to the even pixel line of the liquid crystal display device 10. By applying an incident right eye image signal, a display device for realizing a 3D image is realized.

On the other hand, the glasses 45 for viewing the 3D image as one set with the liquid crystal display device 10 including the lambda / 4 patterned retarder 40 having the above-described configuration, the conventional glasses made of a transparent glass material Polarizing films 50a and 50b and? / 4 retardation film (not shown).

At this time, when wearing the glasses for viewing 3D images, the left eye glasses 45a corresponding to the left eye of the user have a λ / 4 phase film (not shown) and a first polarizing film 50a which serve to convert circularly polarized light into linearly polarized light. Is attached to the eyeglasses 45b for the right eye, and a λ / 4 phase film (not shown) and a second polarizing film 50b are attached to the circularly polarized light selectively.

Accordingly, the liquid crystal display device 10 in which a user wears the 3D image glasses 45 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 the image through the left eye eyeglasses 45a, the left eye image through the right eyeglasses 45b, the right eye image is incident, so the user can view the 3D image by combining these two images. It becomes possible.

However, in the 3D image implementing system 1 having the above-described configuration, the first phase pattern 41a and the second phase pattern 41b having optical axes orthogonal to each other on the front surface of the liquid crystal display device 10 are alternately formed. Since the λ / 4 patterned retarder 40 is provided and the λ / 4 retardation film (not shown) is provided in the glasses 45, the polarization is changed, so that the Polarization conversion proceeds differently for each wavelength. That is, by passing through the [lambda] / 4 patterned retarder 40 and the [lambda] / 4 retardation film (not shown), the characteristic difference of the polarization conversion for each wavelength is increased.

The liquid crystal display 10 has various polarization angles of the finally emitted light according to liquid crystal modes such as twist nematic (TN), in-plane switching (IPS), and vertical alignment (VA). The polarization angle of the final output light is determined by the transmission axis direction of the upper polarizing plate (light exit surface) of the liquid crystal display device, and is usually one of four angles of 0 °, 45 °, 90 °, and 135 ° with respect to the horizontal plane. .

Meanwhile, the patterned retarder type 3D image realization system 1 may include FIGS. 2A to 2D (patterned retarder according to the transmission axis angle of the emission light) according to the final emission direction of the transmission axis of the light emitted from the liquid crystal display device 10. The optical axis arrangement of the patterned retarder 40 is determined as shown in the figure showing the combination of the optical axes, thereby determining the transmission axis of the polarizing film provided in the glasses for viewing 3D images.

Therefore, the conventional patterned retarder type 3D image realization system starts with four types, and since polarization evolves into two types, 3D having a polarizing film having two types of patterned retarder array states. All you need is glasses for watching video.

However, although the glasses for viewing 3D images are reduced to two types according to the patterned retard array method, four types of patterned retards having different arrangement states are considered in consideration of the polarization change of the entire wavelength region. Uniform wavelengths are difficult to obtain because the wavelength dispersion at

 When the wavelength dispersion is minimized, the light emitted from the red, green, and blue pixel regions is uniformly transmitted and incident on the 3D glasses, so that the display quality of the stereoscopic image is good.

However, in FIG. 3 (light having different wavelength bands of a 3D image realization system having conventional two lambda / 4 phase difference films, the lambda / 4 patterned retarder 40 and lambda / 4 phase difference film 43 Referring to the diagram briefly showing the intensity of light after passing through the light, the wavelength refraction occurred.), The red, green, and blue light having passed through the liquid crystal display device 10 have different wavelengths. Although having an intensity, the λ / is designed to pass through the λ / 4 patterned retarder 40 provided on the front surface of the liquid crystal display device 10 so as to change into a left circle or right circle polarization state, and to accurately generate a phase delay according to a 550 nm wavelength. 4 The intensity of the patterned retarder 40 itself does not change for green light having a wavelength range of 550 nm, but a phase error occurs for red light having a larger wavelength band or blue light having a smaller wavelength band. As a result, the strength is reduced, respectively.

In addition, the left or right flattened light passes through the λ / 4 patterned retarder 40 to pass through the λ / 4 retardation film 43 provided in the glasses (not shown), thereby retarding as much as λ / 4. Is generated again to form a linearly polarized state, except for light having a wavelength range of 550nm, light having a wavelength band larger or smaller than this occurs again, and a phase error occurs again. By passing through the polarizing film 50 provided in the (not shown) is the light of the state polarized in a specific direction. In this case, the light passing through the polarizing film 50 has almost no change in the intensity of the light of 550nm wavelength band, the light of the wavelength band larger or smaller than this is reduced.

Therefore, the user who finally views the 3D image through the conventional 3D image realization system detects the color difference due to the change in the intensity of light in each wavelength band, thereby causing display degradation.

That is, when wavelength dispersion occurs, the light emitted from the red, green, and blue pixel areas R, G, and B of the liquid crystal display device 10 passes through the 3D glasses, and then, the red, green, and blue light is emitted. As the intensity of the light is changed, the 3D display quality is deteriorated.

Accordingly, the present invention has been made to solve the above problems, it is a 3D glasses having one type of patterned retarder array state can cope with all patterned retarder type 3D display device, the wavelength dispersion It is an object of the present invention to provide a 3D image realization system that can prevent the degradation of 3D image quality.

The 3D image implementing system 100 according to the first exemplary embodiment of the present invention includes a liquid crystal display 110 for displaying an image having first and second polarizing plates 125 and 130 on both outer surfaces thereof, and the liquid crystal display. Only the λ / 4 patterned retarder 140 provided on the outer surface of the second polarizing plate 130 of the display device 110 and the polarizing films 150a and 150b disposed so as to have transmission axes perpendicular to each other for the left eye and the right eye. Eyeglasses 145 are provided.

First, the liquid crystal display 110 includes an array substrate 115, a color filter substrate 120, a liquid crystal layer (not shown) interposed between the two substrates 115 and 120, and the two substrates 115, 120. Although not shown in the drawings, the first and second polarizing plates 125 and 130 attached to the outer side surfaces of the first polarizing plate 125 include a backlight unit (not shown).

The array substrate 115 is connected to the gate and data lines 116 and 118 and the two lines 116 and 118 that define a plurality of pixel regions P and cross each other to correspond to each pixel region P. A thin film transistor Tr is provided, connected to the thin film transistor Tr, and provided with a pixel electrode 119.

The color filter substrate 120 includes a black matrix 121 corresponding to a boundary of each pixel region P, and a color filter layer 122 including red, green, and blue color filter patterns sequentially corresponding to each pixel region P. FIG. ) And a color filter layer 122 are disposed on the front surface of the common electrode (not shown).

At this time, a common electrode (not shown) provided on the front surface of the color filter substrate 120 according to the mode of the liquid crystal display device 110 is the pixel electrode 119 in each pixel region P of the array substrate 115. It may be formed alternately with).

On the other hand, the first and second polarizing plates (125, 130) is characterized in that the transmission axis is configured to perpendicularly cross each other.

In addition, the λ / 4 patterned retarder 140 provided on the outer surface of the second polarizing plate 130 corresponds to the pixel region P positioned in the odd pixel line in the horizontal direction. Its phase is internally changed so that the light emitted from the second polarizing plate 30 from the above becomes the right circularly polarized state, and the left circularly polarized state corresponding to the pixel region P positioned in the even-numbered pixel line. The birefringent material is alternately patterned for each pixel area P line to have different directions.

In this case, in the λ / 4 patterned retarder 140 such that the phase difference of λ / 4 is generated, the optical axes thereof are respectively + relative to the transmission axis of the second polarizing plate 130 provided in the liquid crystal display device 110. It features 45 degrees and -45 degrees.

On the other hand, the 3D image viewing glasses 145 forming a set with the liquid crystal display device 110 including the lambda / 4 patterned retarder 140 having the above-described configuration is for the left eye made of a transparent glass material and The eyeglasses 145a and 145b for the right eye and the eyeglasses 148 bordering each of the eyeglasses 145a and 145b and seated on a user's ear, and the polarizing films 150a and 150b are provided on the eyeglasses 145a and 145b. And λ / 4 retardation film (not shown) is attached, each of the eyeglasses (145a, 145b) is characterized in that it is configured to be rotated by the user arbitrarily without being fixed to the glasses leg 148 bordering it.

At this time, the left eye glasses 145a and the right eye glasses 145b may be configured to be rotatable separately, or λ / 4 of the left eye glasses 145a and the right eye glasses 145b as shown in the drawing. Since the optical axis angles of the retardation film (not shown) are preferably maintained at 90 degrees to each other, for the convenience of the user, the left eye and right eye glasses 145a and 145b may have the same rotation angle and rotate at the same time. And a rotation adjusting means 146 which is in contact with the right eye glasses 145a and 145b at the same time, and is configured to simultaneously rotate the left eye and right eye glasses 145a and 145b when the rotation adjusting means 146 rotates. It may be.

The rotation control means 146 is an interlocking means, the rim has a sawtooth shape, and the sawtooth-shaped auxiliary means 149 is also provided at the edges of the eyeglasses 145a and 145b, and the rotation control means 146 and Rotation aids 149 of the eyeglasses 145a and 145b are configured to engage with each other so that the left and right eyeglasses 145a and 145b can be rotated at the same time by the rotation adjusting means 146. It would be.

Meanwhile, the λ / 4 phase film (not shown) serves to change circularly polarized light into linearly polarized light on the left eye glasses 145a corresponding to the user's left eye when the 3D image viewing glasses 145 having such a configuration are worn. ) And a first polarizing film 150a, and a λ / 4 phase film (not shown) and a second polarizing film (not shown), which serve to selectively change circularly polarized light into linearly polarized light on the right eyeglasses 145b. 150b) is attached.

Therefore, the user wears the 3D image viewing glasses 145 having such a configuration, and the liquid crystal display 110 for displaying images having different circularly polarized states in which left and right eye image data are applied alternately line by line. When viewing the image through the), the left eye image through the left eye glasses 145a and the right eye image through the right eye glasses 145b, so that the user can view the 3D image by combining these two images. You can watch.

In this case, since the glasses 145 for viewing the 3D image having the above-described configuration may rotate the left and right eyeglasses 145a and 145b, the user may change the eyeglasses according to the mode of the liquid crystal display 110. Since the transmission axis of the polarizing film 150 of the incident surface of 145a and 145b can be aligned, TN (Twist Nematic), IPS (In-Plane Switching), and VA (Vertical) which change the transmission axis arrangement of the second polarizing plate 130 Even if the liquid crystal display 110 having any liquid crystal mode is provided during alignment, the left and right eyeglasses provided with the polarizing film 150 and the λ / 4 phase film (not shown) are rotated to have an appropriate rotation angle. For example, the transmission axis of the second polarizing plate 130 provided in the liquid crystal display device 110 and the transmission axis of the polarizing film 150 provided in each of the eyeglasses 145a and 145b match the wavelength according to the liquid crystal mode characteristic. By minimizing dispersibility, degradation of 3D image quality can be suppressed. The.

 Meanwhile, in the case of the glasses 145 for viewing 3D images according to the first embodiment of the present invention, both the polarizing film 150 and the λ / 4 phase film (not shown) are fixed to the respective eyeglasses 145a and 145b so that each eyeglass ( While the polarizing film 150 and the λ / 4 phase film (not shown) are all rotated at the same time when the 145a, 145b is rotated as an example, as a modification, the polarizing film for each of the eyeglasses (145a, 145b) The polarizing film 150 and the λ / 4 phase film (not shown) may be configured to be rotatable separately by allowing only one component of the 150 or λ / 4 phase film (not shown) to be fixed. That is, the polarizing film 150 and the λ / 4 phase film (not shown) may be configured to not be fixed to each other in the eyeglasses 145a and 145b.

Meanwhile, in the conventional case of the 3D viewing glasses, since the eyeglasses provided with the polarizing film and the λ / 4 phase film are fixed, the 3D image coincides with the transmission axis of the second polarizing plate provided in the liquid crystal display when viewing in a normal attitude. Although the user can lie down, the position of the 3D glasses is rotated 90 degrees in the sitting position, so that the transmission axis of the second polarizing plate provided in the liquid crystal display device and the transmission axis of the polarizing film provided in the 3D viewing glasses are Since they were perpendicular to each other, viewing 3D images was impossible.

However, in the case of the 3D image implementation system 100 having the λ / 4 phase film (not shown) having the above-described configuration and the polarizing film 150 is rotated, the glasses 145 for viewing 3D images, 6A to 6C (showing positions of transmission axes of 3D glasses for each posture of a user wearing 3D viewing glasses capable of rotating the polarizing film λ / 4 phase film provided in the 3D image realization system according to the present invention). For reference, after the user wears the 3D image viewing glasses 145, the 3D image and the transmission axis of the second polarizing plate (not shown) of the liquid crystal display (not shown) may be viewed regardless of any posture. It is another advantage that the 3D image can be viewed by rotating the λ / 4 phase film and the polarizing film more accurately so that the transmission axis of the polarizing film provided in the eyeglasses 145 matches.

FIG. 7 is a diagram illustrating a 3D image implementation system according to a second embodiment of the present invention, and FIG. 8 is a view illustrating glasses for viewing 3D images provided in a 3D image implementation system according to a second embodiment of the present invention. .

It is configured to include a backlight unit provided.

On the other hand, the 3D viewing glasses 245 is made of a pair of eyeglasses 315 which is surrounded by the shutter lens 310 and the shutter lens 310 and seated on both ears of the user. In this case, the shutter lens 310 includes a second liquid crystal panel including third and fourth substrates 322 and 324 facing each other and a second liquid crystal layer 330 interposed between the two substrates 322 and 324.

In this case, a first electrode 326 is formed on an inner side surface of the third substrate 322, and a second electrode 328 is formed on an inner side surface of the fourth substrate 324, and the first and second electrodes are formed. By changing the state of the liquid crystal molecules in the second liquid crystal layer 330 by the voltage difference applied to 326 and 328, the light emitted from the liquid crystal display device 210 is selectively transmitted or blocked.

Accordingly, the time division 3D image realization system 200 according to the second embodiment of the present invention having the above-described configuration may use the left eye only through the left eye shutter lens 250a of the glasses 245 for implementing the 3D image during odd-numbered frames. Only the image is incident, the image is not incident on the right eye shutter lens 250b, and only the right eye image is incident through the right eye shutter lens 250b of the glasses 245 for implementing the 3D image during the even-numbered frames. No image is incident on the lens 250a. In this case, since the unit frame time is several milliseconds (ms), the user feels as if the image information is simultaneously input to the left eye and the right eye without any time difference, and the image information received by the left and right eyes is synthesized to view the 3D image. Done.
