Connecting device

The priority of the present application is back to the Korean Patent No. 2011-0077983 filed on August 5, 2011, to the Korean Patent Office, and the Korean Patent No. 2012-0083052 filed on Jan. 30, 2012, to the Korean Patent Office. The contents disclosed in this case are all incorporated into this case for reference.

The present invention relates to a connecting device and a method of manufacturing a laminate using the same.

In the manufacturing process of a display device, such as a liquid crystal display or other electronic product, it is often necessary to perform a connection process of two or more components. An example of such a process may be for connecting an LCD panel and an optical film to each other, such as a polarizing film or a retardation film. For example, as schematically shown in FIG. 1, in order to construct a 3D image display device, regions (1001, 1002) of right eye signals and left eye signals are generated on the liquid crystal panel 100 (hereinafter referred to as "R signals" and "L signals". The pattern (2001, 2002) for differentially adjusting the polarization states of the R signal and the L signal is formed on the optical filter 200, and the liquid crystal panel 100 and the optical filter 200 should be connected to each other. In the 3D video display device, the signal transmitted from the region 1001 (hereinafter referred to as "UR region") in which the R signal is generated from the liquid crystal panel 100 is adjusted by the optical filter to adjust the polarization state of the R signal 2001 (hereinafter referred to as "FR region"). . Similarly, the signal transmitted from the region 1002 (hereinafter referred to as "UL region") in which the L signal is generated from the liquid crystal panel 100 is adjusted by the optical filter to adjust the polarization state of the L signal 2002 (hereinafter referred to as "FL region"), and the R signal and L signals will be separated from each other Open and then reach the observer. Therefore, it is required that the liquid crystal panel and the optical filter are connected to each other such that the UR region and the filter FR region are matched to each other, and the UL region is highly accurately matched with the FL region of the optical filter. If a portion of the UR area of the liquid crystal panel is connected to the FL area of the optical filter, the R signal cannot enter the right eye but enters the left eye. Therefore, crosstalk means that in the 3D video device, the percentage of the R signal entering the left eye relative to the signal entering the left eye L is increased, making it difficult for the viewer to view the 3D image. Therefore, in the process of manufacturing a 3D display device, it is necessary to utilize a connecting device that can highly accurately connect the liquid crystal panel and the optical film to each other.

The present invention provides a connection device and a method of manufacturing a laminate using the same.

An embodiment of the present invention provides a connecting device including a first supporting portion for fixing a first component, and a second supporting portion including a pressure sensitive adhesive pad for fixing a second component; The transmitting portion is configured to control the relative positions of the first supporting portion and the second supporting portion such that the first member fixed to the first supporting portion and the second member fixed to the second supporting portion are stacked on each other.

In the present specification, it is meant that "the mounting enables the first member to be fixed" means that the first member can be fixed to the first support portion when the connecting device performs a connecting process. The connecting device that is not in operation may not include the first component. Further, it means that "the pressure-sensitive adhesive pad can fix the second member" can have the same meaning.

The terms "first element", "second element", "first support portion" and "second support portion" used in the present specification are arbitrarily set to describe two elements and two support portions. . Thus, the first element can be placed on the second support and the second element can be placed on the first support.

In one embodiment, one of the first and second support portions is permeable to the pressure sensitive adhesive pad securing member. For example, in the present specification, the "second support portion" may mean that the support portion utilizes a pressure-sensitive adhesive pad.

In one embodiment, the pressure sensitive adhesive pad can include a substrate layer and a pressure sensitive adhesive layer formed on a surface of the substrate layer. The first or second component can be loaded onto the surface of the pressure sensitive adhesive layer.

For example, the substrate layer may be a substrate on which a pressure-sensitive adhesive layer is formed. In one embodiment, a transparent polymer substrate, an opaque polymer substrate, and glass may be utilized as the substrate. Further, in the above substrate, in order to observe the arrangement of the elements through a multi-vision system which will be described later, a transparent polymer substrate can be utilized. As an example of the above substrate, a polyester substrate such as polyurethane or polyethylene terephthalate (PET), and an acrylic substrate and the like can also be used.

The first element or the second element is in contact with the pressure sensitive adhesive layer and pressure is applied to the first or second element such that the element can be attached to the pressure sensitive adhesive layer. Conventional ingredients known in the art of pressure sensitive adhesive layers can be used. For example, a porous polymer layer or a cured product of a pressure-sensitive adhesive composition can be used as the pressure-sensitive adhesive layer.

For example, the porous polymer layer can be a material used in glass factories for fixing glass. A plurality of holes may be formed in the above material, and the holes may exist On the surface, the binder can be attached to the above materials. Once a binder is attached, for example, a plate-like member disposed on such a material under appropriate pressure, a vacuum is created by the formation of a hole in the material, so that the element can be fixed to the material although the inhalation procedure is not performed. Such a porous polymer layer, which has been conventionally used in the art, can be used without limitation. For example, a foamed polyester can be used as the porous polymer layer. Foamed polyesters can be made by a variety of methods known in the art. For example, first, a polyester resin to which tetracarboxylic dianhydride is added is introduced into an extruder and melted at a temperature of about 200 °C. The blowing agent is then supplied to the molten mixture through an opening formed at the inlet of the extruder to produce a foamed polyester. For example, a resin obtained by condensation-polymerization of an aromatic dicarboxylic acid and a diol compound can also be used as the polyester resin. Specifically, terephthalic acid, isophthalic acid, naphthoic acid, and diphenyl ether dicarboxylic acid may be examples of aromatic dicarboxylic acids. As the diol compound, ethylene glycol, tetraethylene glycol, cyclohexane dimethanol, and 1,4-butanediol can be used.

In addition, liquids that are easily vaporized, or thermally decomposable compounds, can also act as blowing agents. For example, an inert gas such as carbon dioxide can also be used as a blowing agent. An extruder which can be used in the art to produce a foamed polyester using a polyester resin and a foaming agent can be used without limitation in the present invention. For example, a single-blade propeller, a two-bladed propeller, or a composite propeller can be used as the extruder.

For example, the cured layer of the pressure sensitive adhesive composition may be a viscoelastic material. The above materials can basically have a permanent viscosity at room temperature. Viscoelastic material means that it can be adhered by low pressure and only by applying pressure without using heat, water or solvent to cause adhesion. Applied at appropriate pressure In the state, once the adhesive is adhered to the cured layer, the cured layer exhibits strong retention, cohesion and elasticity. In addition, once the cured layer is separated, the cured layer can be eliminated without residue. If a cured layer is used as the pressure-sensitive adhesive layer, the component can be fixed only by placing the component on the cured layer and applying appropriate pressure. A cured layer comprising a pressure-sensitive adhesive composition known in the field of pressure-sensitive adhesives in a cured state can also be used as the above-mentioned cured layer. To obtain a pressure-sensitive adhesive composition, a curing agent such as isocyanate may be added to, for example, natural rubber, synthetic rubber, vinyl chloride/vinyl acetate copolymer, polyvinyl alkyl ether, polyacrylate or modified polyolefin. In polymers such as pressure sensitive adhesives.

If the pressure-sensitive adhesive layer as described above is used, the indentation process is not required during the fixing process, so that the component can be fixed while the component is kept flat.

Due to the above, it is possible to prevent the component from being curled or waved and to ensure tolerance to warpage of the component. In one embodiment, the member that is secured by the pressure sensitive adhesive pad can be a member that is susceptible to curling or waves, such as a plate or sheet.

In one embodiment, if the components are secured by a pressure sensitive adhesive pad, components of various sizes can also be effectively secured. Therefore, the working efficiency of the connecting device can be improved.

In an embodiment, the first support portion may also utilize the suction of the suction method to fix the first component to the first support portion. For example, the first support portion may include a support piece for holding the first member thereon and having at least one hole formed thereon; and fixing means for fixing the first member while being held on the support piece The first component is used to fix the first component to the support sheet through the suction process.

In an embodiment, in order to prevent the first element from being deflected toward the first support portion due to the suction of the first support portion, the suction at the center of the first support portion can be adjusted to be smaller than the suction at the edge.

In an embodiment, in order to adjust the suction at the center of the first support portion to be smaller than the suction at the edge, the support piece includes a plurality of holes, and the density of the holes formed on the edge of the support piece may be greater than the hole formed at the center of the support piece. density. Here, the density of a pore refers to a surface area ratio of a plurality of pores per unit surface area. For example, it will be understood that if the holes formed on the edge of the support sheet and the center of the support sheet have the same surface area, the high density of the holes means that a plurality of holes are formed in the unit area. Further, referring to FIG. 2, when the entire area of the support piece is divided into three areas having the same area in the transverse direction and is divided into three areas having the same area in the longitudinal direction, the edge 1111 of the support piece Can refer to an area on the edge. Thus, the center 1112 of the support sheet can refer to the area at the center of the support sheet in addition to the edge of the support sheet.

If the support sheet has a hole formed therein, the structure used in the art can be employed without any limitation. For example, a mesh plate can be used as the support sheet.

In an embodiment, like the second support portion, the first support portion may include a pressure sensitive adhesive pad to secure the first member. Here, as the pressure-sensitive adhesive pad included in the first support portion, a pressure-sensitive adhesive pad having the above structure may be employed.

In an embodiment, the attachment device can provide a multi-vision system that can identify the position of the first and second components. For example, the multiple vision system may include a first vision system for observing the state of the first component through the optical signal; and a second vision system for observing the second component through the optical signal The state of the piece; and the total reflection lens. Here, the meaning of "observing the state of the component" can be interpreted as "identifying the position of the component".

A multiple vision system in accordance with an embodiment may construct a visual structure in which the first component and the second component are disposed in a substantially closed configuration. In the closed structure, for example, the distance between the first element and the second element may be 10 mm or less, 9 mm or less, 8 mm or less, 7 mm or less, 6 mm or less, 5 mm or less 4 mm or less, 3 mm or less, 2 mm or less, or 1 mm or less. Furthermore, if the first element and the second element are placed closely together, the degree of precise connection of the first and second elements can be enhanced such that the lower limit of the distance between the first and second elements in the closed structure is not limited. For example, the distance between the first and second elements can be 0 (zero) or more.

The total reflection lens may be a lens through which light passes, or a lens that is completely reflected by light, depending on the angle of incidence. In particular, light input to the total reflection lens may pass through the total reflection lens without refraction, or may be refracted first and then passed through the total reflection lens, or may be totally reflected by the total reflection lens.

In an embodiment, the total reflection lens may be arranged to allow an optical signal emitted from the first visual camera or an optical signal emitted from the second visual camera to pass through the total reflection lens and then to the first element or the second element.

For example, the total reflection lens can be arranged such that one of the optical signals can pass through the total reflection lens and reach one of the first and second elements, while the other signal is completely reflected or refracted by the total reflection lens and then reaches the first and second elements. The other one. The signal passing through the total reflection lens and reaching the first element or the second element may be transmitted without refraction transmission or refraction.

A total reflection lens can be provided such that the optical signal passes through the total reflection lens and reaches one of the first and second elements, and the optical signal is totally reflected or refracted by the total reflection lens and then reaches the other of the first and second elements, The same position of the first and second elements can be reached.

Here, with respect to the same position of the first and second elements, in a state in which the first element and the second element are overlapped, the position of the second element is a hypothesis that penetrates the first element and is perpendicular to the through surface of the first element. The line contact can be interpreted as the same position as the position of the first element. However, in view of actual errors, the same position may be included in the center of the point where the imaginary line is in contact with the second element, to a radius of 5 mm, 3 mm, 1 mm or 0.5 mm.

The first element and the second element can be stacked in a desired configuration by observing the same position of the first and second elements by a multi-vision system.

In an embodiment, in order to allow the same position of the first and second components to be viewed through the multi-vision system, a total reflection lens may be provided such that one of the signals passes through the same position as the other signal is totally reflected or refracted. .

In addition, the total reflection lens can also be arranged to allow the optical signal passing through the total reflection lens to be in the same direction as the optical signal that is totally reflected or refracted on the total reflection lens.

Therefore, the same position of the first and second elements can be observed by setting the total reflection lens such that the position at which one of the signals passes is the same as the position and the direction of the total reflection or refraction of the other signal.

In an embodiment, the first vision camera, the second vision camera, and the total reflection lens may be provided to the first support portion or the second support portion. In this case, the first or second support portion may be provided such that the first or second support portion may be photographed by a visual camera.

In an embodiment, the first vision camera, the second vision camera, and the total reflection lens may be provided to the first support portion. In an embodiment, the first support portion can be used to secure the component by means of suction through the support sheet, such as the aforementioned fastening device. In this case, a mesh plate can be utilized as the support sheet, and the first vision camera, the second vision camera, and the total reflection lens can be placed under the mesh plate. As a result, the first vision camera and the second vision camera can capture the position of the first and second components through the aperture of the mesh panel. In another embodiment, the first support portion can be secured thereto using a pressure sensitive adhesive pad. In this case, the substrate layer and the pressure-sensitive adhesive layer of the pressure-sensitive adhesive pad are usually formed of a material having light transmissivity. However, the present invention is not limited to the above, and if the pressure-sensitive adhesive pad is formed of an opaque material or a translucent material, at least a portion of the pressure-sensitive adhesive pad may also be formed of a transparent material. In the present specification, a portion in which the pressure-sensitive adhesive pad is formed of a transparent material may be referred to as a "visual area". As shown in FIG. 3, in an embodiment, the visual region 1213 can be formed on a pressure sensitive adhesive pad. The method of forming the visual region on the pressure-sensitive adhesive pad is not particularly limited. For example, a transparent sheet having a similar pressure sensitive adhesive pad thickness can be placed over a pressure sensitive adhesive pad to form a visual area.

The pressure sensitive adhesive pad may involve a first support portion. In one embodiment, the pressure sensitive adhesive pad associated with the second support portion has a light transmissive or viscous area formed thereon.

In an embodiment, the connecting device may further include a connecting roller for applying pressure to the stacked body of the first member and the second member stacked on each other by the conveying portion.

In an embodiment, the first and second components may be connected by means of use in the art to which the invention pertains. For example, the first and second components can be joined by an adhesive or a pressure sensitive adhesive. Thus, in one embodiment, the attachment roller can apply pressure to the laminate of the first member and the second member in a state where the adhesive or pressure sensitive adhesive is placed between the first and second members.

In an embodiment, the first component may be a liquid crystal panel. Further, the second member in an embodiment may be an optical film. All films that can be used to connect to the liquid crystal panel can be used as an optical film without limitation. For example, the optical film may be a polarizing plate for displaying a 3D image, a retardation film, or an optical filter.

If the component is held by a pressure sensitive adhesive pad, it is possible to prevent the component from curling or fluctuating. Therefore, in the embodiment in the case where the liquid crystal panel and the optical film are connected, the optical film can be fixed by a pressure-sensitive adhesive pad. However, the invention is not limited thereto. When a liquid crystal panel is used, the liquid crystal panel can be fixed to the support portion by suction or by a pressure sensitive adhesive pad. Further, the liquid crystal panel may be fixed to the support portion by other means than the above method.

In an embodiment, the first component may be a liquid crystal panel formed with a UR region and a UL region thereon, and the second component may be an optical filter for displaying a 3D image and having an FR region and an FL region formed thereon. . Therefore, the connection device may be a manufacturing device of the 3D image display device or a part of the manufacturing device of the 3D image display device.

An embodiment of the invention relates to a method of fabricating a first component and a second component laminate, comprising placing a second component on a pressure sensitive adhesive pad; applying pressure to the second component to secure the second component to the second support And moving the relative positions of the first element and the second element to stack the fixed second element and the first element fixed to the first support to each other.

In this case, after confirming the mounting positions of the first member and the second member, the mounting process can be performed immediately to improve the connection accuracy. However, Figure 4 depicts only one embodiment, in a connection The position at which the multiple vision system is set, and the position at which the roller is mounted, can be easily changed by those skilled in the art.

Referring to Figures 7 and 8, an embodiment is shown showing a first support portion or a second support portion of the attachment device.

The first and second support portions included in the attachment device, one of which may include a pressure sensitive adhesive pad capable of securing the component. For example, the second support portion 12 can include a pressure sensitive adhesive pad 121 that can secure the second component 200. As shown in FIG. 7, in an embodiment, the pressure sensitive adhesive pad 121 may include a substrate layer 1211 and a pressure sensitive adhesive layer 1212 formed on the substrate layer. The pressure sensitive adhesive layer 1212 is a layer that the component can be connected to by contact with it under a certain pressure. For example, the cured layer of the above porous polymer layer or pressure-sensitive adhesive composition can be used as a pressure-sensitive adhesive layer.

In an embodiment, the first support portion may include a pressure sensitive adhesive pad to secure the first component. In this case, the pressure-sensitive adhesive pad of the first support portion may have the same structure as the pressure-sensitive adhesive pad included in the second support portion.

Further, in another embodiment, the first support portion may include the aforementioned support sheet and fixture. An embodiment is shown with reference to Fig. 8, showing a first support portion using a suction method. The support portion 11 may include a support piece 111 on which the first member 100 can be held. For example, the support sheet may have at least one hole 113 formed therein. In this figure, the hole 113 of the support piece 111 is exaggeratedly shown, and the actual hole 113 can be very small. For example, a mesh plate can be utilized as a support sheet.

Furthermore, the first support portion 11 can include a securing device 112 through which the first element 100 can be secured using a suction process. Figure 8, fixed installation The flow direction in which the gas is sucked through the hole 113 of the support piece 111 is indicated by an arrow. The first supporting portion 11 shown in FIG. 8 includes a supporting piece 111 and a fixing device 112, and the optical element 134 is disposed on a region of the supporting piece 111 where no hole is formed to construct the same structure as the first supporting portion of FIG. First support portion.

Although the transmission portion is not shown in FIGS. 4 to 6, the transmission portion may be used to change the relative positions of the first support portion and the second support portion, and the transmission portion commonly used in the technical field of the present invention may be used without limitation. Structure.

The multiple vision system allows the connecting device to connect the first and second components with a high degree of precision.

In an embodiment, the highly precise connection of the first and second elements may mean that the pattern formed thereon includes the first element 100 having different characteristics and the second element and the pattern formed thereon includes a third region of different characteristics and a second member 200 of the fourth region, which are joined to form a laminated body 300, and overlap between the first and third regions of the first and second component laminates with the second and the third There is almost no error in the overlap between the four regions. The above-mentioned errors include manufacturing errors generated in practice, and may include, for example, tolerances of 100 μm or less, 50 μm or less, 30 μm or less, or 10 μm or less.

In an embodiment as shown in FIG. 9, a multiple vision system can be disposed under the first component 100 and the second component 200. As described above, the multi-vision system 13 can include a first vision camera 131, a second vision camera 132, and a total reflection lens 133. For example, as described above, depending on the angle of incidence of the light entering the total reflection lens, The total reflection lens can transmit light without refraction or can be refracted to transmit light first, or can totally reflect light.

In an embodiment shown in FIG. 9, the total reflection lens 133 can be used to refract the optical signal of the first vision camera 131 by the total reflection lens 133 and reach one of the first and second components, and the second vision. The optical signal of camera 132 can pass through the total reflection lens and reach the other of the first and second components. Further, as shown in FIG. 9, the total reflection lens is also used to refract and penetrate the optical signals at the same position on the total reflection lens in the same direction, so that the same positions of the first and second elements can be observed. The above "same position" can be understood as shown in the figure.

If the structure of the first and second component configurations is recognized by the multiple vision system to be similar to the structure for identifying the first and second component laminate configurations, the first component and the second component can be connected with high precision. This is why if the configuration of the first and second elements is identifiable in a state in which the first and second elements are closely arranged, and the first and second elements can be minimized in a state in which the first and second elements remain in a configuration. The reason for the connection. If the structure identifiable by the first and second component configurations is that the first component is spaced apart from the second component by a particular distance, although the configuration of the first and second components is precisely adjusted, when the relative positions of the first and second components are Upon change, the first or second component is offset from the initial configuration to connect the first and second components. Therefore, the connection accuracy of the first and second components may be lowered.

The multi-vision system 13 is configured as in the embodiment shown in Fig. 9, and the position can be recognized on the running link device in a state where the first member 100 and the second member 200 are disposed in a substantially closed configuration. For example, at this time, first The distance between the element and the second element forming the closed structure may be 10 mm or less, 9 mm or less, 8 mm or less, 7 mm or less, 6 mm or less, 5 mm or less, 4 mm or less, 3 mm or less, 2 mm or less, or 1 mm or less. Thus, by utilizing multiple vision systems, the degree of sophistication of the first and second components can be increased.

In an embodiment, the multiple vision system can further include an optical component. For example, light element 134 can function in a process that utilizes a visual camera to identify the position of the component. Additionally, for example, as shown in FIG. 4, light element 134 can be configured to face the first and second vision cameras.

In an embodiment, the attachment roller 14 can be used to apply pressure to the laminate of the first component 100 and the second component 200. At this time, in a state where the relative positions of the first member and the second member are changed by the transport portion, the first member and the second member may be allowed to be stacked on each other.

For example, as shown in FIGS. 4 and 6, the connecting roller 14 may be disposed in the second support portion 12. In an embodiment, the connecting roller 14 can be spaced a distance from the support piece when the connecting device is not in operation. Further, although the connecting device is in operation, the connecting roller 14 may be spaced apart from the pressure sensitive adhesive pad except when the first member and the second member are connected. However, when pressure is applied to the first and second members, the connecting roller 14 is moved and brought into contact with the rear surface of the pressure-sensitive adhesive pad to be applied in a state where the connecting roller is in contact with the rear surface of the pressure-sensitive adhesive pad. Pressure to the first and second components.

The connecting means is a means for connecting the first element and the second element to each other, for example, the connected first element and the second element may be elements of an optical device requiring precise connection. In an embodiment, the first component and the second component One of the components may be a liquid crystal panel, and the other may be an optical film. In addition, the optical film may be a polarizing plate, a retardation film, a protective film or an optical filter for displaying a 3D image.

In an embodiment, the connecting device may be a device for manufacturing a 3D image display device or a device for manufacturing a 3D image display device.

Referring to Fig. 10, there is shown a method of manufacturing the first and second element laminates using the above-described connecting device.

Referring to Figure 10, an embodiment is shown in which the first component 100 can be placed on the first support portion 11. In an embodiment, the first component 100 can be fixed to the first support portion 11 through a suction process or using a pressure sensitive adhesive pad. Further, the second member 200 may be fixed to the second support portion 12. For example, a method of using a pressure-sensitive adhesive pad to fix the second member 200 to the second support portion 12 can be used. The relative position of the first member 100 fixed to the first support portion 11 and the second member 200 fixed to the second support portion 12 is moved by a transport portion (not shown), thereby causing the first member 100 and the second member The elements 200 can be stacked on one another to provide a laminate.

At this time, in order to make the laminated body highly accurately connected, the arrangement of the first and second elements can be adjusted by means of a multi-vision system. Further, in order to connect the first and second members well, pressure may be applied to the laminated body of the first and second members by the connecting rollers.

In an embodiment, the first component may be an element having a different characteristic pattern formed thereon, the pattern comprising the first region 1001 and the second region 1002, and the second component may be formed with a pattern having different characteristics thereon. An element comprising a third region 2001 and a fourth region 2002. As indicated above, for example, the first component may be a liquid crystal panel having a pattern formed thereon, The pattern includes a UR area and a UL area, and the second element may be an optical filter for displaying a 3D image, the pattern including an FR area and an FL area. In other words, the first region and the second region of the liquid crystal panel may be the UR region and the UL region, respectively, and the third region and the fourth region of the optical filter for displaying the 3D image may be the FR region and the FL region, respectively. Therefore, in a state in which the liquid crystal panel for displaying the 3D image and the optical filter are stacked on each other, the multi-vision system can recognize whether the UR region matches the FR region, and whether the UL region matches the FL region. The above matching means that the UR does not overlap with the FL area, but overlaps exactly with the FR area. However, the matching in the above may include manufacturing errors actually produced; as described above, the manufacturing error may be in the range of 100 μm or less, 50 μm or less, 30 μm or less, or 10 μm or less.

If the above match is wrong, the relative position of the first element and the second element can be adjusted to obtain an exact match. Through the above process, the first and second components can be highly accurately connected. In an embodiment, in the case where the laminate is a 3D image display device, the UR region of the liquid crystal panel for displaying the 3D image and the FR region of the optical filter can be accurately matched to each other, and the UL region and the FL region can be accurately The grounds match each other. Therefore, the 3D image display device manufactured by the above manufacturing method rarely has a chance of generating crosstalk interference to generate high quality 3D images.

In one embodiment, the identification of the phase of the first and second components is obtained through a multi-vision system, as described above, in a closed configuration. Therefore, in a state where the first and second elements are configured to match the two elements, the first and second elements can be stacked with only minimal action.

The first and second elements configured by the multiple vision system can be stacked on each other in a state in which the two-element configuration is maintained. If the closed structure of the multiple vision system operates in a state where the first and second elements are in contact with each other, the operation of adjusting the relative positions of the first and second elements for stacking the first and second elements may be omitted.

The first and second element laminates can be formed by providing a conventional adhesive or pressure sensitive adhesive between the first member and the second member. At this time, the first and second members are connected by applying pressure to the first and second element laminates through the connection roller.

The first and second component laminates produced through the above process are unloaded and shipped as a product, or delivered to a subsequent process.

The exemplary connecting device of the present invention can connect various components with high precision. For example, the connection device can connect a liquid crystal panel and an optical filter for displaying 3D images with high precision to provide a 3D image that produces minimal crosstalk interference.
