1. Field of the Invention
The present invention relates to a multi-three-dimensional (3-D) display device.
2. Discussion of the Related Art
In general, a 3-D display device is an apparatus for enabling a viewer to visually recognize a 2-D image as a 3-D image by enabling the viewer to recognize a left eye image in his or her left eye and to recognize a the right eye image in his or her right eye.
Referring to
The display panel 10Q may display a specific image on its screen.
The 3-D glasses 20Q may include a left eye lens corresponding to a left eye image and a right eye lens corresponding to a right eye image.
A method of implementing a 3-D image is described in brief below. As illustrated in
Furthermore, in the right eye frame R, a right eye lens 302 may be turned on and a left eye lens 301 may be turned off. In the left eye frame L, the left eye lens 301 may be turned on and the right eye lens 302 may be turned off.
In this case, an image according to the left eye frame L is recognized by the left eye of a viewer and an image according to the right eye frame R is recognized by the right eye of the viewer, so the viewer may recognize a 3-D image due to the point of view between both eyes.
However, the known 3-D display device is problematic in that only a viewer who wears the 3-D glasses 20Q may recognize a 3-D image.
An object of the present invention is to provide a multiple 3-D display device that enables a viewer who does not wear 3-D glasses to watch a 3-D image.
A multiple 3-D display device in accordance with an embodiment of the present invention may include a first panel, a first 3-D filter in front of the first panel, a second panel disposed adjacent to the first panel in a first direction, and a second 3-D filter disposed in front of the second panel. The interval between the first 3-D filter and the second 3-D filter in the first direction may be smaller than an interval between the first panel and the second panel.
Furthermore, each of the first and the second 3-D filters may include a pixel area for transmitting light generated by a left eye pixel or right eye pixel of each of the first and the second panels without changing the phase of the light.
Furthermore, the direction in which the pixel area extends may be an oblique direction on the basis of the side of the first and the second 3-D filters.

Furthermore, each of the first and the second 3-D filters may include a pixel area for transmitting light generated by a left eye pixel or right eye pixel of each of the first and the second panels without changing a phase of the light. The first panel and the second panel may include a first area and a second area opposite the first area. The first area of the first panel and the second area of the second panel may be disposed adjacent to each other. Assuming that an interval between the center of a first pixel group placed in the first area of the first panel and the center of the first pixel area of the first 3-D filter, corresponding to the first pixel group, in the first direction is a first interval, an interval between the center of the second pixel group placed in the second area of the first panel and the center of the second pixel area of the first 3-D filter, corresponding to the second pixel group, in the first direction is a second interval, an interval between the center of a third pixel group placed in the second area of the second panel and the center of the third pixel area of the second 3-D filter, corresponding to the third pixel group, in the first direction, is a third interval, and an interval between the center of a fourth pixel group placed in the first area of the second panel and the center of the fourth pixel area of the first 3-D filter, corresponding to the fourth pixel group, in the first direction, is a fourth interval, the first interval may be smaller than the second interval and the third interval may be smaller than the fourth interval.
Furthermore, the pixel area may include lens units protruded from each of the first and the second panels so that the lens units become distant from the first and the second panels.
Furthermore, the direction in which the lens units are extended may be an oblique direction based on the sides of the first and the second 3-D filters.
Furthermore, each of the first and the second 3-D filters may include blocking units configured to partitioning adjacent pixel area.

A (1-1)-th driving unit 101 and a (1-2)-th driving unit 102 may supply driving signals to the first panel 100 of the plurality of PDPs 100 to 130. In this case, the (1-1)-th driving unit 101 and the (1-2)-th driving unit 102 may be merged into a single integrated driving unit.

Referring to
Furthermore, driving boards 1010 to 1320 configured to supply driving signals to the first, the second, the third, and the fourth panels 100 to 130 may be disposed on the rears of the first, the second, the third, and the fourth plates 300 to 330. For example, as illustrated in
In this case, the (1-1)-th, the (2-1)-th, the (3-1)-th, and the (4-1)-th driving units 101, 111, 121, and 131 may supply driving signals to the address electrodes of the first, the second, the third, and the fourth panels 300 to 330. Furthermore, the (1-2)-th, the (2-2)-th, the (3-2)-th, and the (4-2)-th driving units 102, 112, 122, and 132 may supply driving signals to the scan electrodes and sustain electrodes of the first, the second, the third, and the fourth panels 300 to 330. Furthermore, the first, the second, the third, and the fourth control units 301, 311, 321, and 331 may control the (1-1)-th, the (2-1)-th, the (3-1)-th, and the (4-1)-th driving units 101, 111, 121, and 131 and the (1-2)-th, the (2-2)-th, the (3-2)-th, and the (4-2)-th driving units 102, 112, 122, and 132.
In this case, the first control unit 301, the (1-1)-th driving unit 101, and the (1-2)-th driving unit 102 may be collectively called a first driving unit. The first driving unit may be considered to supply driving signals to the first PDP 100. Furthermore, the first driving unit may compute the Average Power Level (APL) of image data corresponding to the first PDP 100.
In this case, the second control unit 311, the (2-1)-th driving unit 111, and the (2-2)-th driving unit 112 may be collectively called a second driving unit. The second driving unit may be considered to supply driving signals to the second PDP 110. Furthermore, the second driving unit may compute the APL of image data corresponding to the second PDP 110.
In this case, the third control unit 321, the (3-1)-th driving unit 121, and the (3-2)-th driving unit 122 may be collectively called a third driving unit. The third driving unit may be considered to supply driving signals to the third PDP 120. Furthermore, the third driving unit may compute the APL of image data corresponding to the third PDP 120.
In this case, the fourth control unit 331, the (4-1)-th driving unit 131, and the (4-2)-th driving unit 132 may be collectively called a fourth driving unit. The fourth driving unit may be considered to supply driving signals to the fourth PDP 130. Furthermore, the second driving unit may compute the APL of image data corresponding to the fourth PDP 140.
Each of the PDPs 100 to 130 may implement an image using a frame including a plurality of subfields.
As illustrated in
In this case, the first electrodes 202 and 203 may include scan electrodes 202 Y parallel to each other and sustain electrodes 203 Z parallel to each other. The second electrode 213 may be called an address electrode.
An upper dielectric layer 204 configured to limit the discharge currents of the scan electrodes 202 Y and the sustain electrodes 203 Z and to provide insulation between the scan electrodes 202 Y and the sustain electrodes 203 Z may be disposed in a front substrate 201 in which the scan electrodes 202 Y and the sustain electrodes 203 Z are formed.
A protection layer 205 configured to facilitate discharge conditions may be formed in the front substrate 201 in which the upper dielectric layer 204 is formed. Such a protection layer 205 may include materials having a high secondary electron emission coefficient, for example, magnesium oxide (MgO).
The address electrodes 213 X may be formed on the rear substrate 211. A lower dielectric layer 215 configured to cover the address electrodes 213 X and insulate the address electrodes 213 X may be formed on the rear substrate 211 in which such address electrodes 213 X are formed.
Barrier ribs 212 configured to partition discharge spaces, that is, discharge cells and to have a stripe type, a well type, a delta type, or a beehive type may be formed on the lower dielectric layer 215. Accordingly, first discharge cells configured to emit red (R) light, second discharge cells configured to emit blue (B) light, and third discharge cells configured to emit green (G) light may be formed between the front substrate 201 and the rear substrate 211. The first, the second, and the third discharge cells R, G, and B may collectively form a pixel.
In the discharge cell, the address electrode 213 may intersect the scan electrodes 202 and the sustain electrodes 203. That is, in the discharge cell, the address electrode 213 is formed at a point where it intersects the scan electrodes 202 and the sustain electrodes 203.
The discharge cell partitioned by the barrier ribs 212 may be filled with a specific discharge gas.
Furthermore, a fluorescent layer 214 configured to display an image when an address discharge is generated may be formed in the discharge cell partitioned by the barrier ribs 212. For example, a first fluorescent layer configured to generate red (R) light, a second fluorescent layer configured to generate blue (B) light, and a third fluorescent layer configured to generate green (G) light may be formed in the discharge cell partitioned by the barrier ribs 212.
Furthermore, the address electrodes 213 formed on the rear substrate 211 may have substantially the same width or thickness, but the width or thickness of the address electrode 213 within the discharge cell may be different from that of the address electrode 213 outside the discharge cell. For example, the width or thickness of the address electrode 213 within the discharge cell may be wider or thicker than that of the address electrode 213 outside the discharge cell.
When a specific signal is applied to at least one of the scan electrode 202, the sustain electrode 203, and the address electrode 213, a discharge may be generated in the discharge cell. When a discharge is generated in the discharge cell as described above, ultraviolet rays may be generated by a discharge gas that fills the discharge cell. Such ultraviolet rays may be radiated to the fluorescent particles of the fluorescent layer 214. As a result, the fluorescent particles to which the ultraviolet rays have been radiated emit a visible ray, and thus a specific image may be displayed on a screen of the PDP 100.
An image frame for implementing the gray level of an image in the PDP is described below.
Referring to
Furthermore, each of the plurality of subfields may include an address period in which a discharge cell from which a discharge will not be generated is selected or a discharge cell from which a discharge is generated is selected and a sustain period in which a gray level is implemented depending on the number of times of discharges.
For example, if an image is to be displayed using 256 gray levels, for example, a single frame may be divided into 8 subfields SF1 to SF8 as illustrated in
Alternatively, at least one of the plurality of subfields of the frame may further include a reset period for resetting.
Furthermore, at least one of the plurality of subfields of the frame may not include the sustain period.
The weight of a corresponding subfield may be set by controlling the number of sustain signals supplied in the sustain period. That is, a specific weight may be applied to each of the subfields using the sustain period. For example, the weight of each of the subfields may be set so that it is increased in the ratio of 2n (where n=0, 1, 2, 3, 4, 5, 6, 7) in such a manner that the weight of the first subfield is set to 20 and the weight of the second subfield is set to 21. As described above, various gray levels of an image may be implemented by controlling the number of sustain signals supplied in the sustain period of each of the subfields depending on the weight of each of the subfields.
In this case,
Furthermore, in
A driving waveform for driving each of the PDPs 100 to 130 is described below.
Referring to
For example, in the set-up period SU of the reset period RP, the ramp-up signal RU may be supplied to the scan electrode Y. In a set-down period SD subsequent to the set-up period SU, the ramp-down signal RD may be supplied to the scan electrode Y.
When the ramp-up signal RU is supplied to the scan electrode Y, a weak dark discharge, that is, a set-up discharge, is generated in a corresponding discharge cell due to the ramp-up signal RU. A distribution of wall charges within the discharge cell may become regular by the set-up discharge.
After the ramp-up signal RU is supplied, when the ramp-down signal RD is supplied to the scan electrode Y, a weak erase discharge, that is, a set-down discharge, is generated within the discharge cell. Wall charges of the degree that an address discharge may be stably generated may remain in the discharge cell due to the set-down discharge.
In an address period AP after the reset period RP, a scan reference signal Ybias having voltage higher than the lowest voltage of the ramp-down signal RD may be supplied to the scan electrode Y.
Furthermore, in the address period AP, a scan signal Sc that falls from the voltage of the scan reference signal Ybias may be supplied to the scan electrode Y.
The pulse width of the scan signal Sc supplied to the scan electrode Y in the address period AP of at least one subfield may be different from that of the scan signal Sc of another subfield. For example, the width of a scan signal in a subfield that is placed behind in time may be smaller than that of a scan signal in a subfield that is placed ahead in time. Furthermore, the width of a scan signal according to order of arranged subfields may be gradually reduced as in 2.6 microsecond (μs), 2.3 μs, 2.1 μs, 1.9 μs or may be reduced as in 2.6 μs, 2.3 μs, 2.3 μs, 2.1 μs, . . . , 1.9 μs.
As described above, when the scan signal Sc is supplied to the scan electrode Y, a data signal Dt may be supplied to an address electrode X in response to the scan signal Sc.
When such a scan signal and such a data signal are supplied, a voltage difference between the scan signal Sc and the data signal Dt and a wall voltage attributable to wall charges generated in the reset period RP are added together. As a result, an address discharge may be generated in a discharge cell to which the data signal Dt is supplied.
Furthermore, in the address period AP in which the address discharge is generated, a sustain reference signal Zbias may be supplied to a sustain electrode Z so that the address discharge is effectively generated between the scan electrode Y and the address electrode X.
In a sustain period SP after the address period AP, sustain signals SUS may be supplied to at least one of the scan electrode Y and the sustain electrode Z. For example, the sustain signals may be alternately supplied to the scan electrode Y and the sustain electrode Z.
When the sustain signal SUS is supplied, a sustain discharge, that is, a display discharge, may be generated between the scan electrode Y and the sustain electrode Z of a discharge cell selected by the address discharge because a wall voltage within the discharge cell and the sustain voltage Vs of the sustain signal SUS are added together.
A method of manufacturing the multi-plasma display device in accordance with an embodiment of the present invention is described in brief below.
Referring to
As illustrated in (c), an exhaust tip 250 may be connected to the exhaust hole 240, and an exhaust pump 230 may be connected to the exhaust tip 250.
Furthermore, impurity gases remaining in the discharge space between the front substrate 201 and the rear substrate 211 may be externally discharged using the exhaust pump 230. Furthermore, a discharge gas, such as argon (Ar), neon (Ne), or xenon (Xe), may be injected into the discharge space.
The discharge space between the front substrate 201 and the rear substrate 211 may be seamed using such a method.
Thereafter, as illustrated in (a) of
Accordingly, as illustrated in (b) and (c) of
The seal portion 50 may also be cut in the process of cutting part of the front substrate 201 and the rear substrate 211, as illustrated in (b) and (c) of

For example, as illustrated in
Furthermore, the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 may be disposed so that the cutting faces thereof are adjacent to one another.
For example, a cutting and grinding process may be performed on the second short side SS2 and second long side LS2 of each of the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130.
Furthermore, the first panel 100 and the second panel 110 may be disposed so that the second short side SS2 of the first panel 100 and the second short side SS2 of the second panel 110 are adjacent to each other, and the third panel 120 and the fourth panel 130 may be disposed so that the second short side SS2 of the third panel 120 and the second short side SS2 of the fourth panel 130 are adjacent to each other.
Furthermore, the first panel 100 and the third panel 120 may be disposed so that the second long side LS2 of the first panel 100 and the second long side LS2 of the third panel 120 are adjacent to each other, and the second panel 110 and the fourth panel 130 may be disposed so that the second long side LS2 of the second panel 110 and the second long side LS2 of the fourth panel 130 are adjacent to each other.
In a multi-PDP according to a comparison example different from the multi-PDP of the present invention, a viewer may recognize that an image implemented by the multi-PDP 10 is discontinuously seen through the seam areas 140 and 150.
In contrast, if the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 are disposed so that the cutting faces thereof are adjacent to one another as in the case of
An example in which the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 are disposed in a 2×2 matrix form has been illustrated. For example, the plurality of panels may be disposed in various forms, such as a 1×2 matrix form or a 2×1 matrix form.
For example, as illustrated in
If a multi-PDP is constructed using a number of panels as described above, the panels may be disposed substantially in the same pattern.
A first panel 1000, a second panel 1010, a fifth panel 1100, and a sixth panel 1110 that belong to first to sixteenth panels 1000 to 1330 arranged in a 4×4 matrix form of
Referring to
Furthermore, a cutting and grinding process may be performed on the first and the second short sides SS1 and SS2 and the first and the second long sides LS1 and LS2 of the first panel 1000, the second panel 1010, the fifth panel 1100, and the sixth panel 1110, respectively.
Furthermore, the first panel 1000 and the second panel 1010 may be disposed so that the second short side SS2 of the first panel 1000 and the first short side SS1 of the second panel 1010 are adjacent to each other. The fifth panel 1100 and the sixth panel 1110 may be disposed so that the second short side SS2 of the fifth panel 1100 and the first short side SS1 of the sixth panel 1110 adjacent to each other.
Furthermore, the first panel 1000 and the fifth panel 1100 may be disposed so that the second long side LS2 of the first panel 1000 and the first long side LS1 of the fifth panel 1100 are adjacent to each other. The second panel 1010 and the sixth panel 1110 may be disposed so that the second long side LS2 of the second panel 1010 and the first long side LS1 of the sixth panel 1110 are adjacent to each other.
Referring to
If the first, the second, the third, and the fourth 3-D filters 220 to 223 are disposed in front of the respective PDPs 100 to 130 as described above, a viewer may watch a 3-D image although the viewer does not wear 3-D glasses.
A method of implementing a 3-D image is described below. Although the first panel 100 and the first 3-D filter 220 are described below as an example, the following contents may also be identically applied to the second, the third, and the fourth panels 110 to 130 and the second to the fourth 3-D filters 221 to 223.
As illustrated in
Furthermore, a 3-D filter, for example, the first 3-D filter 220 may include pixel areas PA that transmit light generated by the first panel 100 without changing the phase of the light. In this case, a single pixel area PA may correspond to a plurality of the pixels. Accordingly, the number of pixel areas PA formed in the first 3-D filter 220 may be smaller than the number of pixels formed in the first panel 100.
Furthermore, the first 3-D filter 220 may be physically separated from the first panel 100 at a specific interval QA.
Furthermore, the width QB of the pixel area PA of the first 3-D filter 220 may be smaller than the interval QA between the first panel 100 and the first 3-D filter 220.
A viewer placed at a specific location may detect light generated by specific pixels P3 to P6 through the pixel area PA, as illustrated in
For example, light generated by the third and the fourth pixels P3 and P4 of the plurality of pixels of the first panel 100 may travel to a right eye area RA through the pixel area PA. Accordingly, the right eye RE of a viewer may detect the light generated by the third and the fourth pixels P3 and P4.
Furthermore, light generated by the fifth and the sixth pixels P5 and P6 of the plurality of pixels of the first panel 100 may travel to a left eye area LA through the pixel area PA. Accordingly, the left eye LE of the viewer may detect light generated by the fifth and the sixth pixels P5 and P6.
In this case, the pixel recognized by the right eye RE of the viewer may be called a right eye pixel, and the pixel recognized by the left eye LE of the viewer may be called a left eye pixel. An image into which the point of view between both eyes has been incorporated may be displayed on the right eye pixel and the left eye pixel. That is, an image corresponding to the right eye of a viewer may be implemented in a right eye pixel, and an image corresponding to the left eye of the viewer may be implemented in a right eye pixel.
For example, it is assumed that a viewer watches an image at a specific location {circle around (1)}, as illustrated in
In such a case, the viewer may detect an image of a first right eye pixel RP1 through the first pixel area PA1 of the first 3-D filter 220, may detect an image of a second right eye pixel RP2 through the second pixel area PA2 of the first 3-D filter 220, and may detect an image of a third right eye pixel RP3 through the third pixel area PA3 of the first 3-D filter 220, through his or her right eye.
Furthermore, the viewer may detect an image of a first left eye pixel LP1 through the first pixel area PA1 of the first 3-D filter 220, may detect an image of a second left eye pixel LP2 through the second pixel area PA2 of the first 3-D filter 220, and may detect an image of a third left eye pixel LP3 through the third pixel area PA3 of the first 3-D filter 220, through his or her left eye.
In such ways, a viewer may recognize an image displayed on the first panel 100 in a 3-D way.
Referring to
The base substrate 260 may be substantially transparent in such a way as to transmit light.
The lens unit 261 may refract externally incident light so that an image according to right eye pixels is recognized by the right eye of a viewer and an image according to left eye pixels is recognized by the left eye of a viewer. The size and shape of the lens unit 261 may be changed in various ways.
In such a case, the lens unit 261 may correspond to a pixel area.
Referring to
A viewer may recognize an image according to right eye pixels through his or her right eye and may recognize an image according to left eye pixels through his or her left eye, through the pixel area PA partitioned by the blocking units 262.
The blocking unit 262 may have a variety of types of shapes.
For example, as illustrated in (A) of
If the blocking units 271 are formed using the engraving method as described above, the thickness QC of the base substrate 270 may be thicker than the thickness of base substrate 260 illustrated in
Alternatively, as illustrated in (B) of
The pixel area may have various patterns.
For example, as illustrated in (A) and (B) of
If the pixel areas of the first 3-D filter 220 have the vertical patterns as described above, a plurality of discharge cells or unit cells arranged in parallel in the horizontal direction DH of the display panel may gather to form pixels P1, P2, and P3, as illustrated in
Alternatively, as illustrated in (A) and (B) of
If the pixel areas of the first 3-D filter 220 have the oblique patterns as described above, a plurality of discharge cells or unit cells obliquely arranged in the oblique direction of a display panel may gather to form pixels P1, P2, and P3, as illustrated in

When the case of
A structure configured to maintain the interval between the panel and the 3-D filter may be disposed between two adjacent PDPs. The structure is described below.
If the first panel 100 and the second panel 110 are disposed adjacent to each other as illustrated in (A) of
For example, it is assumed that each of the first panel 100 and the second panel 110 includes a first area and a second area opposite the first area and the first area of the first panel 100 and the second area of the second panel 110 are disposed adjacent to each other. In other words, as illustrated in (B) of
The first area and second area of each of the first panel 100 and the second panel 110 are hereinafter defined as described above.
In such a case, the first side cover 100Q may be placed on the side of the first panel 100 and the first 3-D filter 220 in the second area of the first panel 100 and may maintain the interval QA between the first panel 100 and the first 3-D filter 220. Furthermore, the first side cover 100Q may be connected to the first 3-D filter 220.

Furthermore, the second side cover 110Q may be connected to the second 3-D filter 221.
Furthermore, as illustrated in (B) of
That is, the structure 200Q may enable the first panel 100 to be spatially separated from the first 3-D filter 220 and enable the second panel 110 to be spatially separated from the second 3-D filter 221.

To this end, the width QE of the structure 200Q in the horizontal direction DH of the first and the second panels 100 and 110 may be greater than each of an interval QE1 between adjacent 3-D filters and an interval QE2 between adjacent panels.
Furthermore, the structure 200Q may be overlapped with a dummy area placed in the outer wall of an active area on which a screen is displayed in the vertical direction DV of the first, the second panel 100, 110. In other words, the structure 200Q may be overlapped with a seam area SA between the first panel 100 and the second panel 110 in the vertical direction DV of the first and the second panels 100 and 110. More specifically, the structure 200Q may be overlapped with the seal layers 50A and 50B of the first panel 100 and the second panel 110 in the vertical direction DV of the first and the second panels 100 and 110.

In such a case, the interval between the first and the second panels 100 and 110 and the interval between the first and the second 3-D filters 220 and 221 may be regularly maintained.
Referring to
In this case, the thickness QE of the structure 200Q in an area overlapped with the air gaps 120Q and 121Q in the horizontal direction DH of the first and the second panels 100 and 110 may be greater than the thickness QF1 of the structure 200Q in an area overlapped with the first and the second panels 100 and 110. In such a case, the size of the seam area SA can be prevented from being excessively increased.
Referring to
In this case, the thickness QE of the structure 200Q in the area overlapped with the air gaps 120Q and 121Q in the horizontal direction DH of the first and the second panels 100 and 110 may be greater than the thickness QF2 of the structure 200Q in the area overlapped with the first and the second 3-D filters 220 and 221.

Alternatively, as illustrated in (A) and (B) of
Alternatively, as illustrated in
In this case, the seventh and the eighth extension portions 208Q and 209Q may include portions extended from the body portion 201Q and configured to travel in the horizontal direction of the first and the second panels 100 and 110 and portions configured to travel in the vertical direction of the first and the second panels 100 and 110.

Furthermore, the adhesive layer 300Q may be disposed between the first body portion 201Qa and the second body portion 201Qb.
In such a case, a portion disposed between the first panel 100 and the second panel 110 in the horizontal direction DH of the first and the second panels 100 and 110 may be omitted from the first, the second body portion 201Qa, 201Qb.
In order to maintain the interval between the first and the second panels 100 and 110 and the interval between the first and the second 3-D filters 220 and 221, a transparent substrate may be disposed between the first and the second panels 100 and 110 and between the first and the second 3-D filters 220 and 221. This is described below.
Referring to
In such a case, the interval between the panels and the 3-D filters can be regularly maintained over the entire multiple 3-D display device.
Such a transparent substrate 400Q, 410Q may be a substrate made of glass materials or a substrate made of resin materials.
Although the transparent substrate is disposed between the panel and the 3-D filter as described above, a structure may be added.
For example, as illustrated in
Referring to
In other words, the fifth extension portion 206Q of the structure 200Q may be placed between the first panel 100 and the first transparent substrate 400Q, and the sixth extension portion 207Q may be placed between the second panel 110 and the second transparent substrate 410Q.

Furthermore, an air gap 122Q may be formed between the first 3-D filter 220 and the first transparent substrate 400Q, and an air gap 123Q may also be formed between the second 3-D filter 221 and the second transparent substrate 410Q.
An example in which the multiple 3-D display device in accordance with an embodiment of the present invention includes three or more PDPs is described below.
For example, a case where the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 are arranged in a 2×2 matrix form as illustrated in
In such a case, as illustrated in (A) of
Alternatively, as illustrated in (B) of
The structures 200QA and 200QD preferably may be disposed between two adjacent panels in the horizontal direction because image characteristics according to the horizontal direction of a display panel have a great influence on picture quality on the nature of the visual characteristics of a human eye, as illustrated in (B) of
Alternatively, as illustrated in
In such a case, as illustrated in
The transparent substrate may be attached to the panel.
For example, as illustrated in
In such a case, a first adhesive layer 310Q may be formed between the first transparent substrate 400Q and the first panel 100, and a second adhesive layer 320Q may be formed between the second transparent substrate 410Q and the second panel 110.
Alternatively, as illustrated in
If the transparent substrate is attached to the panel using adhesives as described above, the interval between the panel and the 3-D filter can be regularly maintained even without a separate structure.
The 3-D filter may be attached using adhesives.
For example, as illustrated in (A) of
Alternatively, as illustrated in (B) of
This may be possible when the thickness of the base substrate 260a, 260b is sufficiently thick.
The interval between two adjacent 3-D filters may be smaller than the interval between two adjacent panels. This is described below, but a description of portions described in detail above is omitted for simplicity.
Referring to (A) of
In this case, the first 3-D filter 220 and the second 3-D filter 221 may be spaced apart from each other at a specific interval QG1 in the horizontal direction of the first and the second panels 100 and 110. Furthermore, the first panel 100 and the second panel 110 may be spaced apart from each other at a specific interval QG2. The interval QG1 between the first 3-D filter 220 and the second 3-D filter 221 may be smaller than the interval QG2 between the first panel 100 and the second panel 110.
That is, the first 3-D filter 220 and the second 3-D filter 221 may be disposed relatively closely.
In such a case, as illustrated in
Furthermore, the length QJ1 of the first 3-D filter 220 may be longer than the length QH1 of the first panel 100 in the horizontal direction of the first and the second panels 100 and 110.
Furthermore, the length QJ2 of the second 3-D filter 221 may be longer than the length QH2 of the second panel 110 in the horizontal direction of the first and the second panels 100 and 110.
In such a case, the air gaps 120Q and 121Q may be formed between the first 3-D filter 220 and the first panel 100 and between the second 3-D filter 221 and the second panel 110.
Furthermore, the structure 200Q may be disposed in an area between the first panel 100 and the second panel 110.
For example, as illustrated in
In such a case, the first, the second transparent substrate 400Q, 410Q may be disposed between the first, the second panel 100, 110 and the first, the second 3-D filter 220, 221. Furthermore, the first 3-D filter 220 may be further extended by a specific length QK3 compared to the first transparent substrate 400Q, and the second 3-D filter 221 may be further extended by a specific length QK4 compared to the second transparent substrate 410Q.
Alternatively, as illustrated in
If the interval QG1 between the first 3-D filter 220 and the second 3-D filter 221 is smaller than the interval QG2 between the first panel 100 and the second panel 110 as described above, at least one of the first 3-D filter 200 and the second 3-D filter 221 may be overlapped with the area between the first panel 100 and the second panel 110 in the vertical direction of the first and the second panels 100 and 110.
For example, if the 3-D filter 220, 221 includes the base substrate 260a, 260b and the lens units 261a, 261b as illustrated in (A) of
Alternatively, if the 3-D filter 220, 221 includes the base substrate 260a, 260b and the blocking units 262a, 262b as illustrated in (B) of
If the interval between two adjacent 3-D filters in the area between two adjacent panels is smaller than the interval between the two adjacent panels as described above, the size of the seam area SA between the two adjacent panels may be made so that it is seen to be small.
For example, if the interval between two adjacent 3-D filters in the area between two adjacent panels is greater than or the same as the interval between the two adjacent panels, the seam area SA may be significantly seen, as illustrated in (A) of
In contrast, if the interval between two adjacent 3-D filters in the area between two adjacent panels is made smaller than the interval between the two adjacent panels as in an embodiment of the present invention, an optical effect that enables the seam area SA to be seen to be dim or small can be obtained, as illustrated in (B) of
The reason for this is that light is refracted so that the size of the seam area SA is seen to be small in the seam area SA between the first and the second 3-D filters 220 and 221.
Accordingly, picture quality of a 3-D image implemented on a screen of the multiple 3-D display device can be improved.
It is assumed that the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 are arranged in a 2×2 matrix form as illustrated in
In such a case, as illustrated in (A) of
In contrast, as illustrated in (B) of
The size of at least one 3-D filter may be made greater than that of a display panel. This is described below, and redundant descriptions are omitted.
As illustrated in (A) of
Furthermore, as illustrated in (B) of
Furthermore, the length QL1 of the first 3-D filter 220 and the length QL2 of the second 3-D filter 221 in the horizontal direction of the first and the second panels 100 and 110 may be different. In this case, the length QL1 of the first 3-D filter 220 is illustrated as being longer than the length QL2 of the second 3-D filter 221, and vice versa.
Furthermore, the first 3-D filter 220 may be overlapped with part of the second panel 110 in addition to the first panel 100 in the vertical direction of the first and the second panels 100 and 110.
In such a case, the first 3-D filter 220 may be overlapped with pixels of the second panel 110 in addition to pixels of the first panel 100 in the vertical direction of the first and the second panels 100 and 110. At least one pixel area PA of the first 3-D filter 220 may correspond to or may be overlapped with pixels of the second panel 110 in the vertical direction of the first and the second panels 100 and 110.
Accordingly, a viewer may watch some images of the second panel 110 through the first 3-D filter 220, and a structure opposite the aforementioned structure may be possible.
In the aforementioned structure, as described with reference to
Referring to
In such a case, the first adhesive layer 310Q may be formed between the first transparent substrate 400Q and the first panel 100, and the second adhesive layer 320Q may be formed between the first transparent substrate 400Q and the second panel 110 and between the second transparent substrate 410Q and the second panel 110.
It is assumed that the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 are arranged in a 2×2 matrix form as illustrated in
In such a case, the first 3-D filter 220 may be overlapped with the second, the third, and the fourth panels 110, 120, and 130 in addition to the first panel 100.
Furthermore, the second 3-D filter 221 may be overlapped with the second panel 110 and the fourth panel 130, and the third 3-D filter 222 may be overlapped with the third panel 120 and the fourth panel 130.
In contrast, the fourth 3-D filter 223 may be overlapped with the fourth panel 130.
In such a case, a visual effect that enables the size of the seam area SA between two adjacent panels to be seen to be small or dim can be obtained.
Such a case corresponds to a structure in which the size of the seam area SA in the vertical direction and the horizontal direction is seen to be small or dim.
Alternatively, as illustrated in
Furthermore, the third 3-D filter 222 may be overlapped with the third panel 120 and the fourth panel 130.
In contrast, the second 3-D filter 221 may be overlapped with the second panel 130, and the fourth 3-D filter 223 may be overlapped with the fourth panel 130.
In such a case, a visual effect that enables the size of the seam area SA between two panels adjacent to each other in the horizontal direction to be seen to be small or dim can be obtained.
In a multiple 3-D display device in accordance with an embodiment of the present invention, the center view of each of PDPs preferably may be moved to the area of two adjacent panels.
For example, if the first panel 100 and the second panel 110 are adjacent to each other in a multiple 3-D display device in accordance with an embodiment of the present invention, a center view may be placed in the boundary area of the first panel 100 and the second panel 110, as illustrated in
If the center view of the first panel 100 is formed at a location {circle around (1)} and the center view of the second panel 110 is formed at a location {circle around (2)} as illustrated in
In contrast, in a multiple 3-D display device in accordance with an embodiment of the present invention, if the center view is moved to an area between two adjacent panels as in the case of

First, it is assumed that as illustrated in
In such a case, as illustrated in (A) of
Furthermore, as illustrated in (B) of
In such a case, the first interval may be smaller than the second interval.
In other words, assuming that the first panel 100 and the second panel 110 include a first area and a second area opposite the first area, respectively, and the first area of the first panel 100 and the second area of the second panel 110 are disposed adjacent to each other, the center view of the first panel 100 may be disposed close to the first area of the first panel 100.
Furthermore, as illustrated in
In such a case, as illustrated in (A) of
Furthermore, as illustrated in (B) of

Assuming that a straight line CL1a vertical to the center of a first pixel area PA1 is a first straight line as illustrated in (A) of
Assuming that a straight line CL1b vertical to the center of a second pixel area PA2 is a third straight line as illustrated in (B) of
In such a case, the tenth interval may be smaller than the eleventh interval.
The reason for this is that the center view of each panel has moved from the central area of the panel to the boundary area of two adjacent panels.
It is assumed that the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 are arranged in a 2×2 matrix form, as illustrated in
In such a case, as illustrated in (A) of
For example, the center views of the first panel 100 and the second panel 110 adjacent to each other in the horizontal direction may be moved to the boundary area of the first panel 100 and the second panel 110.
Such a case may correspond to a case where the center views of the panels have been moved in the horizontal direction.
Alternatively, as illustrated in (B) of
Such a case may correspond to a case where the center views of the respective panels have been moved in the horizontal direction and the vertical direction.
In order to arrange a plurality of display panels in an N×M matrix form, a cradle may be required. This is described below, and redundant descriptions are omitted.
A multiple 3-D display device in accordance with an embodiment of the present invention may include a plurality of main frames, one or more cradles disposed in each of the main frames, a display panel connected to the panel cradle, a 3-D filter disposed in front of the display panel, a filter cradle connected to the edge of the 3-D filter, and a filter connection unit configured to connect the filter cradle to the main frame. This is described in detail below.

Furthermore, rollers 600 may be installed at the ends on both sides of the panel cradle 500.
The rollers 600 installed at the ends of the panel cradle 500 may be inserted into the groove 410 formed in the main frame 400. Accordingly, the display panel cradled in the panel cradle 500 may be freely moved within the main frame 400 left and right.
Referring to (a), (b), and (c) of
The diameter of the guide rollers 620 may be smaller than that of the main roller 610, and the axis of the guide rollers 620 may be the same as that of the main roller 610.
The main roller 610 and the guide rollers 620 may be separately formed and combined, thus forming a single roller 600. Alternatively, in order to maintain the strength of the roller 600 to a sufficiently high level, the main roller 610 and the guide rollers 620 may be integrated and formed.
As illustrated in
The main roller 610 may be freely moved along the groove 410 in accordance with the guide of the guide rollers 620.
Referring to
Furthermore, as illustrated in
In this case, the first buffer portion 420 and/or the second buffer portions 520 may include rubber materials for reducing a shock. Alternatively, if a case where the first buffer portion 420 and/or the second buffer portions 520 are capable of separating the panel cradle 500 and/or the roller 600 and the main frame 400 at a specific interval is taken into consideration, the amount of shock occurring when the panel cradle 500 and/or the roller 600 and the main frame 400 collide against each other can be reduced although the first buffer portion 420 and/or the second buffer portions 520 include metallic materials.
For example, the first buffer portion 420 may include rubber materials.
Although a user strongly moves the display panel cradled in the panel cradle 500 in the direction of an arrow indicated in
Referring to
Furthermore, the size of the second buffer portion 520 does not need to be large only if the second buffer portion 520 has only to prevent the panel cradle 500 and/or the roller 600 from colliding against the main frame 400 and/or the first buffer portion 420.
For example, as illustrated in

To this end, holes 531 may be formed in the sides of the support 530, holes 501 may be formed in the sides of the panel cradle 500, and the support 530 and the panel cradle 500 may be fixed using specific clamping means 530 through the holes 531 of the support 530 and the holes 501 of the panel cradle 500.
A display panel may be cradled in the panel cradle 500. In order for the display panel to be cradled in the panel cradle 500 as described above, fixing portions 700 may be disposed at the back of the plate 300 disposed at the back of the display panel 100, as illustrated in
