Abstract
Description
[Technical Field]
[0001] This invention relates to a display device, and more particularly to a display device that can be fitted with components having specific functions (e.g., an induction antenna with signal transmission and reception capabilities). [Previous Technology]
[0002] Japanese Patent Publication No. 2007-257483 discloses a conventional display device that, in addition to display function, also has contactless IC card read / write function, and includes a frame, a liquid crystal display unit housed in the frame, and a read / write unit composed of elements such as an antenna, wherein the read / write unit is disposed on the back side of the liquid crystal display unit opposite to its display area.
[0003] However, the frame of the conventional display device does not have a structure that allows the read / write unit to be directly installed or removed from the outside. Therefore, when it is necessary to install or remove the read / write unit, the frame and the liquid crystal display unit must be separated before the relevant work can be carried out, which is extremely inconvenient for operators. In addition, frequent disassembly of the frame can easily lead to deformation or damage to the frame, which will not only affect the appearance of the display device, but also reduce the protective effect of the frame on the read / write unit and the liquid crystal display unit. Thus, the reliability and durability of the conventional display device will be reduced. [Summary of the Invention]
[0004] Therefore, the object of the present invention is to provide a display device that can overcome at least one disadvantage of the prior art.
[0005] The present invention provides a display device, comprising a display module and a frame disposed on the rear side of the display module. The frame and the rear side of the display module together define an accommodating space, and the frame forms an opening communicating with the outside and the accommodating space.
[0006] By having the opening in the frame, components with specific functions (e.g., induction antennas) can be directly installed from the outside of the frame into the receiving space of the frame through the opening, or the components can be removed from the receiving space through the opening, without separating the frame and the display module. Thus, the display device of the present invention not only ensures its reliability and durability, but also greatly improves the convenience of replacing different functional components, thereby meeting consumers' customization needs.
[0007] The present invention also provides a display device, comprising a display module, a frame, a sensing antenna, and a ferrite sheet. The frame is disposed on the back side of the display module, defining an accommodating space together with the back side of the display module, and forming an opening communicating with the outside and the accommodating space. The sensing antenna comprises a first portion and a second portion connected together, the first portion being located within the accommodating space, and the second portion extending from the first portion through the opening of the frame to the outside of the frame. The ferrite sheet is located within the accommodating space and disposed between the sensing antenna and the frame.
[0008] By having the opening in the frame, the sensing antenna can be directly installed from the outside of the frame into the receiving space of the frame through the opening, or the sensing antenna can be directly removed from the receiving space through the opening, without separating the frame and the display module. Thus, the display device of the present invention can ensure its reliability and durability.
Implementation Method
[0010] Before the present invention is described in detail, it should be noted that the drawings mentioned in the following description are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed, and the layout may also be more complex.
[0011] Referring to Figures 1 to 3, a first embodiment of the display device of the present invention includes a display module 1 and a frame 2, wherein the display module 1 has opposite front and back sides, the front side is used for display, and the frame 2 is disposed on the back side of the display module 1.
[0012] In the first embodiment, the display module 1 is a liquid crystal display (LCD) and includes a liquid crystal panel 11, a backlight unit 12 disposed on the back side of the liquid crystal panel 11, a scratch-resistant sheet 14 disposed on the back side of the backlight unit 12, and a control unit 13, but the present invention is not limited thereto. In other embodiments, the display module 1 may also be an organic light-emitting diode (OLED) display or a light-emitting diode (LED) display, etc.
[0013] The liquid crystal panel 11 can be a different type of liquid crystal panel, such as a twisted nematic (TN) liquid crystal panel, a multi-domain vertical alignment (MVA) liquid crystal panel, an in-plane switching (IPS) liquid crystal panel, or a fringe field switching (FFS) liquid crystal panel.
[0014] The backlight unit 12 includes a light source, a light guide mechanism, and a reflective sheet. The light source is disposed on one side of the light guide mechanism. The light guide mechanism may include an optical film and a light guide plate to guide the light emitted by the light source toward the liquid crystal panel 11 and to homogenize the light emitted by the light source to form a surface light source. The reflective sheet is disposed on the back side of the light guide plate opposite to the back side of the liquid crystal panel 11, and reflects the light emitted from the back side of the light guide plate toward the liquid crystal panel 11 to improve the luminous efficiency of the backlight unit 12. The scratch-resistant sheet 14 covers the reflective sheet of the backlight unit 12. Here, the scratch-resistant sheet 14 may cover the entire reflective sheet or only a part of the reflective sheet. It should be noted that when the display module 1 is a self-emissive organic light-emitting diode display or a light-emitting diode display, the display module 1 does not have the backlight unit 12.
[0015] The control unit 13 is electrically connected to the traces in the liquid crystal panel 11, and can drive and control the display of the liquid crystal panel 11. It includes a flexible substrate 131 electrically connected to the scan lines and data lines of the liquid crystal panel 11, and a control circuit board 132 electrically connected to the traces in the flexible substrate 131. In the first embodiment, the flexible substrate 131 is a flexible printed circuit board (FPC), and the control circuit board 132 is a printed circuit board (PCB), but the present invention is not limited thereto.
[0016] It should be noted that the liquid crystal panel 11, the backlight unit 12, and the control unit 13 are existing technologies and are not within the scope of this invention. The more detailed structure and operating principle of these components will not be explained here.
[0017] Referring to FIG. 3, the frame 2 and the back of the display module 1 together define an accommodating space 20, and form an opening 23 communicating with the outside and the accommodating space 20. Furthermore, in the first embodiment, as shown in FIG. 1 and FIG. 2, the opening 23 is formed into a narrow and elongated shape that allows a sheet-like object to pass through. In the first embodiment, the frame 2 is made of a metallic material (e.g., aluminum), but the present invention is not limited thereto. In other embodiments, the frame 2 may also be made of other materials (e.g., plastic).
[0018] In the first embodiment, as shown in FIG3, the frame 2 includes an outer frame portion 21 surrounding the periphery of the liquid crystal panel 11 and the periphery of the backlight unit 12, and a protrusion portion 22 protruding from the outer frame portion 21 in a direction away from the display module 1. The outer frame portion 21 and the protrusion portion 22 are formed integrally. The outer frame portion 21 surrounds the protrusion portion 22 (see FIG1), and the inner peripheral end of the outer frame portion 21 is connected to the outer peripheral end of the protrusion portion 22. The receiving space 20 is defined by the inner wall of the protrusion portion 22, the inner peripheral wall of the outer frame portion 21, and the back surface of the display module 1, but the present invention is not limited thereto. In other variations, the frame 2 may not include the protrusion portion 22 (not shown). In other words, in the present invention, the receiving space 20 is defined between the frame 2 and the back surface of the display module 1. However, in other embodiments, the outer frame portion 21 may also be configured to surround the periphery of the backlight unit 12 but not the periphery of the liquid crystal panel 11. In the first embodiment, as shown in FIG3, the opening 23 is formed on the outer frame portion 21 and the protrusion 12, but the present invention is not limited thereto. In other embodiments, the opening 23 may be formed only on the protrusion 12 or only on the outer frame portion 21.
[0019] In the first embodiment, as shown in FIG3, the display device further includes a ferrite sheet 4 located within the receiving space 20 and attached to the inner wall of the frame 2, but the present invention is not limited thereto. In a variation shown in FIG4, the ferrite sheet 4 is not attached to the inner wall of the frame 2.
[0020] In the first embodiment, the display device further includes a sensing antenna. As shown in FIG5, the sensing antenna 3 can be inserted into the opening 23 at an appropriate angle from the outside of the frame 2, and then enter and be installed in the receiving space 20. It should be noted that in the first embodiment, the outer frame portion 21 defines the periphery of the opening 23 with a first chamfer 211, and the protrusion portion 22 defines the periphery of the opening 23 with a second chamfer 221. With the structure of the first chamfer 211 and the second chamfer 221, when the sensing antenna 3 enters the receiving space 20 through the opening 23, the sensing antenna 3 can be prevented from being scratched or abraded by the periphery of the outer frame portion 21 and the protrusion portion 22. Furthermore, there is an appropriate distance between the first chamfer 211 and the second chamfer 221 so that the sensing antenna 3 can enter the receiving space 20 at a better angle, so that the sensing antenna 3 can be smoothly installed in the receiving space 20. Furthermore, when the narrow, elongated opening 23 is formed only on the protrusion 12 or only on the outer frame 21, the opening 23 needs to have an appropriate width to ensure that the sensing antenna 3 can smoothly enter the receiving space 20 through the opening 23. After the sensing antenna 3 is installed, the ferrite sheet 4 is located between the sensing antenna 3 and the frame 2. Also, when the sensing antenna 3 is installed in the configuration shown in FIG. 4, there is no ferrite sheet 4 between the sensing antenna 3 and the frame 2. It should be noted that by configuring the anti-scratch sheet 14, the backlight unit 12 (i.e., the reflector sheet) can be prevented from being scratched, rubbed, or damaged during the process of the sensing antenna 3 entering the receiving space 20, thus enhancing the protection function of the backlight unit 12.
[0021] In the first embodiment, the accommodating space 20 is used to accommodate the sensing antenna 3 with signal transmission and reception function, so that the display device of the present invention can be used to sense signals emitted by mobile devices (e.g., smartphones, electronic watches and other wearable devices, tablet computers, IC cards, etc.).
[0022] It should be noted that in the first embodiment, the example described is that the sensing antenna 3 is inserted into the receiving space 20 of the frame 2, but the present invention is not limited thereto. In other embodiments, according to the consumer's needs, components with other functions (e.g., a Global Positioning System (GPS) component, etc.) can be inserted into the receiving space 20 from the outside of the frame 2 through the opening 23 and installed in the receiving space 20, so that the display device of the present invention has the required functions.
[0023] The sensing antenna 3 can receive signals emitted by the mobile device. The sensing antenna 3 can communicate with the mobile device, for example, via Near-field communication (NFC), WiFi, or Bluetooth. The mobile device can be, for example, a smartphone with NFC functionality, a tablet computer with NFC functionality, or an IC card using Radio-frequency identification (RFID) technology.
[0024] As shown in FIG. 5, the sensing antenna 3 includes a sensing part 31 and a reading part 32 electrically connected to the sensing part 31. When the sensing antenna 3 is installed in the receiving space 20 of the frame 2, the reading part 32 and the sensing part 31 are respectively disposed on opposite sides of the frame 2 (i.e., the reading part 32 is disposed on the back side of the frame 2, outside the receiving space 20). The reading part 32 includes a reader circuit substrate capable of reading the signal received by the sensing part 31. In the first embodiment, as shown in FIG. 5, the reading part 32 and the sensing part 31 are formed on the same flexible printed circuit board and electrically connected to each other. One part of the flexible circuit board (i.e., the sensing part 31) is located inside the receiving space 20, and the other part (i.e., the reading part 32) extends to the outside of the frame 2 through the opening 23 of the frame 2. In other embodiments, the reading unit 32 is formed on a printed circuit board and electrically connected to the sensing unit 31 (e.g., via wire bonding or a connector). In another embodiment, the sensing unit 31 is formed on a flexible printed circuit board, the reading unit 32 is formed on a printed circuit board, and the printed circuit board and the flexible printed circuit board are electrically connected via a connection line passing through the opening 23 of the frame 2. This connection line is a signal transmission line, such as a coaxial cable. In yet another embodiment, the reading unit 32 may have the function of writing information into the mobile device.
[0025] It should be noted that, in the first embodiment, both the display module 1 and the sensing antenna 3 can be connected to a device (e.g., a computer) with signal transmission and processing functions. Specifically, the device can receive the signal read by the reading unit 32 of the sensing antenna 3, process it, and then transmit the processed signal to the display module 1, and display relevant information through the display module 1. However, the present invention is not limited thereto.
[0026] It should be noted that the protrusion 22 can be appropriately modified as needed, changing its projected shape or projected area size in the top-view direction (the vertical direction facing the front of the display module 1, i.e., the direction from bottom to top in Figure 3) on a reference plane perpendicular to the top-view direction. For example, when the sensing antenna 3 is installed in the receiving space 20, the projected area of the protrusion 22 can be equal to, greater than, or even much greater than the projected area of the sensing part 31 of the sensing antenna 3 (see Figure 5). When its proportion of the projected area relative to the frame 2 is increased, a larger receiving space 20 can be provided, thereby providing the degree of freedom in the setting of the sensing antenna 3, and also providing enough space to accommodate multiple sensing antennas 3. In the first embodiment, the length and width of the sensing part 31 of the sensing antenna 3 are 60mm and 40mm respectively, and the projected area of the protrusion 22 is much larger than the projected area of the sensing part 31 (see Figure 8), but the present invention is not limited thereto.
[0027] In the first embodiment, as shown in FIG5, the display device further includes a fixing unit 5 for fixing the sensing antenna 3 and a sealing member 6 for sealing the receiving space 20. The fixing unit 5 includes a double-sided adhesive for attaching the sensing antenna 3 to the frame 2 (see FIG5). Specifically, the double-sided adhesive is used to attach the reading part 32 of the sensing antenna 3 to the outside of the frame 2, thereby fixing the sensing antenna 3. After the sensing antenna 3 is fixed, the receiving space 20 is sealed with the sealing member 6, thereby preventing external dust or particles from entering the receiving space 20 through the opening 23 and contaminating the sensing part 31. In other embodiments, the fixing unit 5 may also include, for example, a locking fastener for locking the sensing antenna 3 to the frame 2.
[0028] In another embodiment, as shown in FIG7, the fixing unit 5 includes an adhesive patch for fixing the sensing antenna 3 to the frame 2. Specifically, the adhesive patch is attached across the outer side of the protrusion 22, the reading part 32 of the sensing antenna 3, and the outer side of the outer frame 21. This not only fixes the reading part 32 of the sensing antenna 3 to the outside of the frame 2, but also seals the opening 23 to prevent external dust or particles from entering the receiving space 20 through the opening 23.
[0029] In the variation shown in FIG. 6, the display device further includes an inductive antenna 3 to which the ferrite sheet 4 is attached; that is, the ferrite sheet 4 is pre-attached to the inductive antenna 3. The inductive antenna 3 can enter the receiving space 20 from the outside of the frame 2 at an appropriate angle through the opening 23, and is installed in the receiving space 20 with the ferrite sheet 4 facing the inner wall of the frame 2. Thus, after the inductive antenna 3 is installed, the ferrite sheet 4 is located between the inductive antenna 3 and the frame 2.
[0030] In the first embodiment, as shown in FIG8, the projected area of the ferrite sheet 4 is equal to or greater than the projected area of the sensing part 31 of the inductive antenna 3. This can more effectively suppress signal interference from the metal frame 2 or other external components to the sensing part 31. Therefore, by ensuring that the projected area of the ferrite sheet 4 is equal to or greater than the projected area of the sensing part 31, the communication quality of the inductive antenna 3 can be effectively improved, but the present invention is not limited thereto.
[0031] In a variation shown in FIG. 9, the display device further includes a support member 8 disposed within the receiving space 20, and the length of the narrow and elongated opening 23 is designed to allow the sensing antenna 3 to pass through. In the first embodiment, the support member 8 is made of insulating material, but the present invention is not limited thereto. Specifically, the support member 8 is pre-installed within the receiving space 20. The support member 8 has a cutout portion 81 that can accommodate the sensing portion 31 of the sensing antenna 3. The cutout portion 81 is formed on the side edge of the support member 8 and communicates with the opening 23. The sensing antenna 3 can enter the cutout portion 81 of the support member 8 through the opening 23 and be properly accommodated therein. After the sensing antenna 3 is installed, the support member 8 substantially fills the portion of the receiving space 20 not occupied by the sensing antenna 3 and the ferrite sheet 4. By configuring the support member 8, the sensing part 31 located in the receiving space 20 can be effectively supported. In this way, the sensing part 31 can be prevented from being displaced in the frame 2, thereby causing the sensing position to shift. Also, friction between the sensing part 31 and the frame 2 can be prevented from generating debris or particles.
[0032] The difference between the variation shown in Figure 10 and the variation shown in Figure 9 is that the length of the opening 23 is designed to allow the support member 8 to pass through. The inductive antenna 3 can be pre-installed in the hollow portion 81 of the support member 8 and enter the receiving space 20 through the opening 23 together with the support member 8 to complete the installation, but the present invention is not limited thereto. In another embodiment, the support member 8 can be placed in the receiving space 20 through the opening 23 first, and then the inductive antenna 3 can enter the receiving space 20 through the opening 23 and be installed in the hollow portion 81.
[0033] The difference between the variation shown in Figure 11 and the variation shown in Figure 10 is that the cutout portion 81 is formed at the center of the support member 8. The sensing element 31 of the induction antenna 3 is pre-installed in the cutout portion 81 of the support member 8, and together with the support member 8, enters the receiving space 20 through the opening 23 to complete the installation. After the induction antenna 3 and the support member 8 are installed, the induction antenna 3 and the support member 8 substantially fill the receiving space 20, thus fixing the sensing element 31 within the receiving space 20. This variation not only fixes the sensing element 31 but also prevents external dust or particles from contaminating the sensing element 31. To simplify the illustration, the reading part 32 of the sensing antenna 3 is omitted from Figure 11. In actual implementation, the reading part 32 can be disposed together with the sensing part 31 in the hollow part 81 of the support member 8, or it can be disposed outside the frame 2 and electrically connected to the sensing part 31 located in the receiving space 20 through a connecting line.
[0034] It should be noted that in Figures 9 to 11, the hollow part 81 of the support member 8 is drawn with a gap between it and the sensing part 31 of the induction antenna 3. This is only to illustrate the positional relationship between the sensing part 31 and the hollow part 81, and does not represent the size ratio between the sensing part 31 and the hollow part 81.
[0035] Referring to Figures 12 and 13, the second embodiment of the display device of the present invention is similar to the first embodiment, except that: the opening 23 is formed in the outer frame portion 21 of the frame 2, and is formed to have an appropriate length and width. The receiving space 20 is defined by the inner peripheral wall of the outer frame portion 21 and the back surface of the display module 1. The protrusion 22 is a separable component from the outer frame portion 21. The protrusion 22 removably covers the opening 23. The display device further includes a positioning unit 9 for positioning the protrusion 22. In the second embodiment, the positioning unit 9 includes four generally L-shaped engaging members 91 disposed on the outer side wall of the outer frame portion 21 (the outer side being the side away from the display module 1). Each engaging member 91 includes a connecting end connected to one of the outer frame portions 21 and a free end opposite to it. The engaging members 91 are paired opposite each other, and the free ends of each pair of engaging members 91 face each other (see FIG. 12). The engaging members 91 and the outer wall of the outer frame portion 21 together define an engaging space. However, in this invention, the structure and configuration of the positioning unit 9 are not limited to the above description.
[0036] As shown in FIG12, the sensing part 31 and the support member 8 of the sensing antenna 3 can be inserted into the receiving space 20 in a flat manner through the opening 23 in the direction from top to bottom in FIG12. Then, the protrusion 22 can slide into the engaging space in the horizontal direction in FIG12 (that is, the horizontal direction perpendicular to the imaginary line connecting the free ends of each pair of engaging members facing each other), thereby covering the opening 23 to fix the sensing part 31 and the support member 8 in the receiving space 20. Here, as shown in FIG13, the protrusion 22 is fixed to the outer frame part 21 by engaging with the engaging members 91, that is, the protrusion 22 is engaged and fixed by the engaging members 91 and the outer wall of the outer frame part 21. It should be noted that in this embodiment, the ferrite sheet 4 (see Figure 13) can be placed on the sensing part 31 after the sensing part 31 is placed, and then the protrusion 22 can be installed. Alternatively, it can be pre-installed on the inner wall of the protrusion 22 and installed and positioned together with the protrusion 22 by sliding in.
[0037] In a variation of the second embodiment shown in Figures 14 and 15, the positioning unit 9 includes four locking fasteners 92, such as, but not limited to, four screws with external threads (not shown); the outer frame portion 21 has four locking holes 212, such as, but not limited to, four screw holes with internal threads (not shown) that can engage with the external threads of the screws; and the protrusion 22 has four through holes 222, the positions of which correspond to the screw holes of the outer frame portion 21. Here, after the sensing portion 31 and the support member 8 are placed in the receiving space 20, the protrusion 22 can cover the opening 23 in the downward direction shown in Figure 14, and align the through holes 222 of the protrusion 22 with the screw holes of the outer frame portion 21. Then, the screws are screwed into the screw holes through the through holes 222. This secures the protrusion 22 to the outer frame 21, simultaneously fixing the sensing part 31 and the support member 8 within the receiving space 20. It should be noted that, here, the locking devices 92 are described using a screw as an example, but the invention is not limited thereto. In other embodiments, the locking devices 92 can also be, for example, pins or rivets. Those skilled in the art will understand that the shape of the locking holes 212 needs to be adjusted accordingly.
[0038] It should be noted that in this second embodiment, the protrusion 22 completely covers the opening 23 after installation, but the present invention is not limited thereto; in other embodiments, a gap (not shown) may be left at the opening 23 after the protrusion 22 is installed, and the reading part 32 of the sensing antenna 3 may extend to the outside of the frame 2 through the gap. The sensing antenna 3 may also be installed into the receiving space 20 by insertion through the gap. In this way, the freedom of installation method of the sensing antenna 3 and the support member 8 can be improved.
[0039] Furthermore, for the sake of simplicity, Figures 12 to 15 do not show the reading section 32 of the sensing antenna 3. In fact, the reading section 32 can be disposed on the outer side of the outer frame 21 or the protrusion 22 and electrically connected to the sensing section 31 located in the receiving space 20 through a connecting line (not shown), or it can be disposed together with the sensing section 31 in the hollowed-out portion 81 of the support member 8. When the reading section 32 is disposed on the outer side of the outer frame 21 or the protrusion 22, the connecting line can be electrically connected to the sensing section 31 through a through hole (not shown) formed in the protrusion 22 or the aforementioned gap.
[0040] It is worth noting that when the liquid crystal panel 11 of the display module 1 is an inversely coupled plasma (IPS) liquid crystal panel or a free-frontal coupled plasma (FFS) liquid crystal panel, the pixel electrode and common electrode, which are made of transparent conductive materials such as indium tin oxide (ITO), are located on the thin-film transistor array substrate and there are slits between these electrodes. Therefore, the transmission signal between the sensing antenna 3 and the mobile device can be partially transmitted to the sensing antenna 3 or the mobile device through the display module 1 via these slits.
[0041] Therefore, when the liquid crystal panel 11 is a lateral electric field conversion type liquid crystal panel or a boundary electric field conversion type liquid crystal panel, the display device of the present invention can not only have a better viewing angle and better color reproduction, but also better communication quality. Furthermore, when the common electrode impedance of the liquid crystal panel 11 is in the range of 50Ω to 200Ω, the shielding of the common electrode on the transmitted signal can be reduced, thus further improving the signal transmission efficiency of the display device of the present invention.
[0042] Based on the above description, the advantages of the display device of the present invention can be summarized as follows:
[0043] First, by means of the structure of the frame 2 having the opening 23, components with specific functions (e.g., induction antennas) can be directly installed from the outside of the frame 2 through the opening 23 into the receiving space 20 of the frame 2 without separating the frame 2 and the display module 1, or the components can be removed from the receiving space 20 through the opening 23. Thus, the display device of the present invention not only ensures its reliability and durability, but also greatly improves the convenience of replacing different functional components, thereby meeting consumers' needs for customization.
[0044] Second, by fixing the sensing antenna 3 with the fixing unit 5, displacement of the sensing antenna 3 within the frame 2 can be avoided, which would lead to a shift in the sensing position. In this way, the display device of the present invention can be ensured to have good sensing or communication quality.
[0045] Third, by means of the chamfered corners 211 and 221 of the frame 2 and the anti-scratch plate 14 of the display module 1, the induction antenna 3 or the backlight unit 12 can be prevented from being scratched, rubbed or scratched during the installation of the induction antenna 3.
[0046] Fourth, by configuring the ferrite sheet 4 such that its projected area on the reference plane in the top view direction is equal to or greater than the projected area of the sensing part 31 of the induction antenna 3, the signal interference of the metal frame 2 or other external components to the sensing part 31 can be effectively suppressed.
[0047] Fifth, by sealing the containment space 20 with the sealing element 6 or the fixing unit 5, external dust or particles can be prevented from entering the containment space 20.
[0048] Sixth, by maximizing the accommodation space 20, the freedom of setting the induction antenna 3 can be ensured.
[0049] 7. By supporting the sensing part 31 of the sensing antenna 3 with the support member 8, it is possible to prevent the sensing part 31 from shifting within the frame 2, and also to prevent friction between the sensing part 31 and the frame 2, which would generate debris or particles. In this way, the display device of the present invention can be ensured to have good durability.
[0050] However, the above description is only an embodiment of the present invention and should not be construed as limiting the scope of the present invention.
