CROSS-REFERENCE TO RELATED APPLICATION  
       [0001]     This application claims priority to and the benefit of Korean Patent Application No. 10-2005-0045187 filed in the Korean Intellectual Property Office on May 27, 2005, the entire content of which is incorporated herein by reference.  
       BACKGROUND OF THE INVENTION  
       [0002]     (a) Field of the Invention  
         [0003]     The present invention relates to a plasma display panel (PDP). More particularly, the present invention relates to a PDP having an enhanced arrangement of pixels and electrodes that enables higher integration of pixels.  
         [0004]     (b) Description of the Related Art  
         [0005]     Generally, a PDP is a display device which excites phosphors with vacuum ultraviolet rays radiated from plasma obtained through gas discharging, and displays desired images by visible light such as red (R), green (G), and blue (B) colors generated by the excited phosphors. The PDP has been spotlighted as a flat panel display for television and industrial purposes with several advantages. The PDP can realize a very large screen size of 60″ or more with a thickness of 10 cm or less, and involves excellent color representation, without image distortion due to viewing angles, since it is a self emissive display, such as a cathode ray tube (CRT). The PDP further involves high productivity and low production cost as it is made in a more simplified manner as compared to a liquid crystal display (LCD).  
         [0006]     A three-electrode surface-discharge type of PDP may be considered as an example of a typical PDP. The three-electrode surface-discharge type of PDP includes a first substrate having sustain electrodes and scan electrodes on the same surface, and a second substrate disposed apart from the first substrate by a predetermined distance and having address electrodes elongated perpendicular to the direction of the sustain and scan electrodes. A discharge gas is filled between the two substrates of the PDP. For each discharge cell of the PDP, whether the discharge cell will be discharged is determined by a discharge between the scan electrode and address electrode corresponding thereto, and a sustain discharge that actually displays a required image occurs between the sustain electrode and scan electrode formed on the same plane.  
         [0007]      FIG. 5  and  FIG. 6  are top plan views illustrating exemplary arrangements of pixels and electrodes in conventional PDPs.  FIG. 5  shows a stripe structure of barrier ribs of a PDP, and  FIG. 6  shows a delta structure of barrier ribs of a PDP.  FIG. 5  and  FIG. 6  respectively illustrate only partial views of display areas of PDPs, and thus it should be understood that the indices n and m in  FIGS. 5 and 6  may respectively indicate arbitrary integers.  
         [0008]     As shown in  FIG. 5 , in the PDP with the stripe structure of barrier ribs, discharge cells are respectively formed between sustain electrodes Xn to Xn+3 and scan electrodes Yn to Yn+3 that are disposed opposing each other, forming a discharge gap therebetween. Each pixel  61  of such a PDP includes three adjacent discharge cells  61 R,  61 G,  61 B of respectively red, green, and blue colors. Address electrodes  65  are formed to cross corresponding discharge cells among the discharge cells  61 R,  61 G,  61 B forming the pixels  61 .  
         [0009]     Therefore, regarding sixteen pixels  61  shown in the drawing, twelve address electrodes  65  (that is, Am, Am+1, . . . , Am+11) are required in total since four pixels are arranged in respective rows and each pixel requires three address electrodes. Further, as the resolution of PDPs becomes higher, discharge cells are required to be arranged more densely. Accordingly, adjacent address electrodes  65  are required to be disposed closer together, and in this case, capacitance C between the adjacent address electrodes increases resulting in an increase of energy consumption (which is calculated as CV 2 f) of the PDP.  
         [0010]     In addition, as shown in  FIG. 6 , in the PDP with the delta-shaped rib structure, discharge cells form separate spaces partitioned by barrier ribs. Each pixel  71  of such a PDP includes three adjacent discharge cells  71 R,  71 G,  71 B of respectively red, green, and blue colors that are arranged in a triangular pattern. Address electrodes  75  are formed to cross corresponding discharge cells among the discharge cells  71 R,  71 G,  71 B forming the pixels  71 .  
         [0011]     In this case also, regarding sixteen pixels  71  shown in the drawing, twelve address electrodes  75  (that is, Am, Am+1, . . . , Am+11) are required in total since four pixels are arranged in respective rows and each pixel requires three address electrodes. In this case also, discharge cells are required to be arranged more densely as the resolution of PDPs becomes higher. Consequently, adjacent address electrodes  75  are required to be disposed closer together, and in this case, capacitance C between the adjacent address electrodes increases resulting in an increase of energy consumption (which is calculated as CV 2 f) of the PDP.  
       SUMMARY OF THE INVENTION  
       [0012]     The present invention has been made in an effort to provide a PDP having advantages of a reduced number of address electrodes corresponding to each pixel, thereby minimizing an increase of power consumption for a PDP of higher resolution as well as reducing manufacturing cost of the PDP.  
         [0013]     An exemplary plasma display panel according to an embodiment of the present invention includes a front substrate and a rear substrate having opposing surfaces and a plurality of discharge cells partitioned in a space therebetween, a plurality of address electrodes formed along a first direction between the front and rear substrates, and a plurality of display electrodes formed along a second direction between the front and rear substrates and electrically separated from the plurality of address electrodes. Here, at least two discharge cells among a plurality of discharge cells included in respective pixels correspond to a same address electrode so as to be driven thereby.  
         [0014]     The at least two discharge cells corresponding to the same address electrode may have phosphor layers of different colors.  
         [0015]     The plurality of display electrodes may include a plurality of pairs of a sustain electrode and a scan electrode that correspond to respective discharge cells. In addition, the numbers of scan electrodes and address electrodes corresponding to each pixel may satisfy a ratio of “the number of address electrodes: the number of scan electrodes=8:3”.  
         [0016]     The plurality of display electrodes may respectively include a pair of protrusion electrodes formed at a borderline between adjacent discharge cells and protruding therefrom toward centers of the adjacent discharge cells. The plurality of scan electrodes may be formed along borderlines between pairs of adjacent discharge cells and may apply a common voltage to the pairs of adjacent discharge cells.  
         [0017]     The pixels may respectively include discharge cells of red, green, and blue colors. In this case, the pixels may respectively include three discharge cells, and centers of the three discharge cells may be arranged in a triangular pattern. The discharge cells may be respectively formed in a shape of a hexagon or a rectangle. A borderline between a pair of discharge cells adjacent along the first direction may be formed such that it may cross, when extended, centers of discharge cells adjacent along the second direction.  
         [0018]     In addition, two subpixels among a plurality of subpixels included in each pixel may be arranged adjacent to each other along the second direction.  
         [0019]     In an exemplary PDP according to another embodiment of the present invention, discharge cells of at least two different colors may correspond to a same address electrode. In this case, discharge cells of all of red, green, and blue colors may correspond to the same address electrode.  
         [0020]     Each of a pair of discharge cells corresponding to the same address electrode and adjacently formed along the first direction may have a phosphor layer of a different color.  
         [0021]     In an exemplary PDP according to yet another exemplary embodiment of the present invention, two address electrodes correspond to each pixel including a plurality of discharge cells. In this case, ¾ of a scan electrode may correspond to each pixel.  
         [0022]     As described above, in a PDP according to an exemplary embodiment of the present invention, an arrangement of pixels is enhanced such that at least two subpixels among a plurality of discharge cells included in respective pixels correspond to the same address electrode. Therefore, the number of address electrodes corresponding to each pixel is reduced and thus an increase of address power consumption for a higher resolution panel may be reduced.  
         [0023]     In addition, since the number of address electrodes required for the entire panel is reduced, the manufacturing cost of a PDP may be reduced.

     DETAILED DESCRIPTION  
       [0030]     As shown in  FIGS. 1 and 2 , a PDP according to the present exemplary embodiment is a so-called delta arrangement cell PDP in which three subpixels of red, green, and blue colors in each pixel are arranged in a triangular pattern.  
         [0031]     The PDP includes a rear substrate  10  and a front substrate  30  disposed substantially in parallel and combined together with a predetermined space therebetween.  
         [0032]     Barrier ribs  23  having a predetermined height and pattern and partitioning pixels  120  are formed between the rear substrate  10  and the front substrate  30 . Here, each pixel  120  includes three subpixels  120 R,  120 G,  120 B arranged in the above-mentioned triangular pattern.  
         [0033]     The subpixels  120 R,  120 G,  120 B are also partitioned by the barrier ribs  23 , and they respectively have corresponding discharge cells  18 .  
         [0034]     According to the present exemplary embodiment, plan shapes of the respective subpixels  120 R,  120 G,  120 B are formed in a generally hexagonal shape, and the barrier ribs  23  partitioning them are formed in a hexagonal or honeycomb pattern. Therefore, the discharge spaces  18  of the respective subpixels  120 R,  120 G,  120 B are formed in a shape of a hexagonal prism that is open at its top.  
         [0035]     The discharge cells  18  are provided with a plasma gas including xenon Xe, neon Ne, etc, for the plasma discharge. Phosphor layers  25  of red, green, and blue colors are respectively formed in the subpixels  120 R,  120 G,  120 B of red, green, and blue colors. Here, the phosphor layers  25  are formed at bottoms of the discharge cells  18  and lateral sides of the barrier ribs  23 .  
         [0036]     In addition, on the rear substrate  10 , a plurality of address electrodes  15  are spaced along a first direction (i.e., y-axis direction in the drawing) below the discharge cells  18  (in more detail, between the rear substrate and the barrier ribs). In addition, a dielectric layer  12  covering the address electrodes  15  is formed on an entire surface of the rear substrate  10 , and it is also formed below the barrier ribs  23 .  
         [0037]     On the front substrate  30 , a plurality of display electrodes  35  are spaced along a second direction (i.e., x-axis direction in the drawing). The display electrodes  35  include pairs of a sustain electrode  32  and a scan electrode  34 , each pair of which forms a discharge gap and corresponds to respective discharge cells  18 . In addition, the sustain electrode  32  and the scan electrode  34  respectively include bus electrodes  32   a ,  34   a  and transparent electrodes  32   b ,  34   b . Here, the bus electrodes  32   a ,  34   a  are formed generally in parallel along the second direction (i.e., x-axis direction in the drawing) on the front substrate  30 , and the transparent electrodes  32   b ,  34   b  protrude from the bus electrodes  32   a ,  34   a  into the discharge cell  18  of the subpixels  120 R,  120 G,  120 B.  
         [0038]     The bus electrodes  32   a ,  34   a  may be formed of a metallic material, and each one of them is formed in a zigzag pattern along its elongated direction since they are elongated along the barrier ribs  23 . In order to minimize blocking of visible light generated in the discharge cells  18  during the operation of the PDP, the bus electrodes  32   a ,  34   a  may be formed with minimized widths and be disposed at the top of the barrier ribs  23 .  
         [0039]     The transparent electrodes  32   b ,  34   b  are formed of a transparent material such as indium-tin-oxide (ITO), and they respectively protrude from the bus electrodes  32   a ,  34   a  into a pair of discharge cells  18  adjacent to respective bus electrodes  32   a ,  34   a . Therefore, in each discharge cell  18 , a pair of transparent electrodes  32   b ,  34   b  are disposed facing each other with a predetermined gap therebetween.  
         [0040]     In addition, on the front substrate  30 , a dielectric layer (not shown) covering the display electrodes  35  may be applied to an entire surface of the front substrate  30 , and a protective layer (not shown) formed of, e.g., MgO may be further applied thereon.  
         [0041]     Hereinafter, an arrangement of pixels and electrodes of a PDP according to the first exemplary embodiment of the present invention will be described in more detail with particular reference to  FIG. 2 . According to the present exemplary embodiment, two address electrodes  15  correspond to each pixel  120 . Here, each pixel  120  includes the three subpixels  120 R,  120 G,  120 B of red, green, and blue colors, and centers of the subpixels  120 R,  120 G,  120 B are arranged in the triangular pattern. For each pixel  120 , at least two of the subpixels  120 R,  120 G,  120 B are driven by the same address electrode  15 .  
         [0042]     In addition, according to the present exemplary embodiment, plan shapes of the discharge cells  18  of the respective subpixels  120 R,  120 G,  120 B are formed in a generally hexagonal shape. A borderline between a pair of discharge cells  18  adjacent along the elongation direction (i.e., y-axis direction in the drawing) of an address electrode  15  is formed such that it may cross, when extended, centers of discharge cells adjacent along a direction (i.e., x-axis direction in the drawing) crossing the address electrode  15 .  
         [0043]     The scan electrodes  34  among the display electrodes  35  are formed along borderlines between pairs of the adjacent discharge cells  18 , and the scan electrodes  34  apply a common voltage to the pairs of adjacent discharge cells  18 . In the same way, the sustain electrodes  32  among the display electrodes  35  are formed along borderlines between pairs of the adjacent discharge cells  18 , and the sustain electrodes  32  apply a common voltage to the pairs of adjacent discharge cells  18 . Therefore, the scan electrodes  34  and the sustain electrodes  32  are alternately disposed along the elongation direction of the address electrode  15 , and each of them controls the discharge of the pairs of discharge cells  18 . For a scan electrode  34  passing through the pixels  120 , three of four protruding transparent electrodes  34   b  lie within each pixel  120 . That is, since each pixel  120  includes three subpixels, two protruding transparent electrodes  34   b  lying on the borderline between two subpixels and one protruding transparent electrode  34   b  lying on a boundary of the other subpixel lie within the pixel  120 . Therefore, it may be regarded that ¾ of a scan electrode  34  corresponds to each pixel  120 .  
         [0044]     Since two address electrodes  15  and ¾ of a scan electrode  34  correspond to each pixel  120  in the present exemplary embodiment, the number of address electrodes  15  and scan electrodes  34  required for driving the PDP satisfies a ratio shown in the following Equation 1.  
         [0000]     (Equation 1) 
 
the number of address electrodes:the number of scan electrodes=8:3  (Equation 1) 
 
         [0045]     In the exemplary arrangement shown in  FIG. 2 , a total of sixteen pixels  120  are arranged in the partial view since four columns of pixels  120  are arranged in the horizontal direction and four rows of pixels  120  are arranged in the vertical direction. Since two address electrodes  15  correspond to each column of pixels  120 , a total of eight address electrodes  15  (that is, Am to Am+7) correspond to all columns of pixels  120  shown in the drawing. In addition, since ¾ of a scan electrode  34  corresponds to each row of pixels  120 , a total of three scan electrodes  34  (that is, Yn, Yn+1, and Yn+2) correspond to all rows of pixels  120  shown in the drawing. The same as the scan electrodes  34 , a total of three sustain electrodes  32  (that is, Xn, Xn+1, and Xn+2) correspond to all rows of pixels  120  shown in the drawing.  
         [0046]     In such an arrangement of pixels, adjacent subpixels (for example, referring to the subpixels indicated by the reference numerals  120 G,  120 B) on the same address electrode  15  have phosphor layers of different colors. In such a way, subpixels having phosphor layers of the three different colors may be alternately arranged on the same address electrode  15 .  
         [0047]     In comparison with the conventional PDPs shown in  FIG. 5  and  FIG. 6 , only eight address electrodes are required to drive sixteen pixels arranged in a matrix pattern of 4×4 according to the present exemplary embodiment, while a total of twelve address electrodes are required to drive sixteen pixels arranged in a conventional matrix pattern. Therefore, the number of address electrodes required to drive the same number of pixels may be reduced.  
         [0048]      FIG. 3  is a top plan view partially showing an arrangement of pixels and electrodes of a PDP according to a second exemplary embodiment of the present invention.  
         [0049]     According to the present exemplary embodiment, plan shapes of the discharge cells  28  of the respective subpixels  220 R,  220 G,  220 B are formed in a generally rectangular shape. A borderline between a pair of discharge cells  28  adjacent along the elongation direction (i.e., y-axis direction in the drawing) of an address electrode  15  is formed such that it may cross, when extended, centers of discharge cells adjacent along a direction (i.e., x-axis direction in the drawing) crossing the address electrode  15 .  
         [0050]     As seen in  FIG. 3 , according to the present exemplary embodiment, two address electrodes  15  correspond to each pixel  220 . Here, each pixel  220  includes the three subpixels  220 R,  220 G,  220 B of red, green, and blue colors, and centers of the subpixels  220 R,  220 G,  220 B are arranged in the triangular pattern. For each pixel  220 , at least two of the subpixels  220 R,  220 G,  220 B are driven by the same address electrode  15 .  
         [0051]     The scan electrodes  34  among the display electrodes  35  are formed along borderlines between pairs of adjacent discharge cells  28 , and the scan electrodes  34  apply a common voltage to the pairs of adjacent discharge cells  28 . In the same way, the sustain electrodes  32  among the display electrodes  35  are formed along borderlines between pairs of adjacent discharge cells  28 , and the sustain electrodes  32  apply a common voltage to the pairs of adjacent discharge cells  28 . Therefore, the scan electrodes  34  and the sustain electrodes  32  are alternately disposed along the elongation direction of the address electrode  15 , and each of them controls the discharge of the pairs of discharge cells  28 .  
         [0052]     For a scan electrode passing through the pixels  220 , three of four protruding transparent electrodes  34   b  lie within each pixel  220 . That is, since each pixel  120  includes three subpixels, two protruding transparent electrodes  34   b  lying on the borderline between two subpixels and one protruding transparent electrode  34   b  lying on a boundary of the other subpixel lie within the pixel  220 . Therefore, it may be regarded that ¾ of a scan electrode  34  corresponds to each pixel  220 . Therefore, according to the present exemplary embodiment, the number of address electrodes  15  and scan electrodes  34  required for driving the PDP satisfies a ratio shown in the above Equation 1, the same as in the first exemplary embodiment.  
         [0053]     In the exemplary arrangement shown in  FIG. 3 , a total of sixteen pixels  220  are arranged in the partial view since four columns of pixels  220  are arranged in the horizontal direction and four rows of pixels  220  are arranged in the vertical direction. Since two address electrodes  15  correspond to each column of pixels  220 , a total of eight address electrodes  15  (that is, Am to Am+7) correspond to all columns of pixels  220  shown in the drawing. In addition, since ¾ of a scan electrode  34  corresponds to each row of pixels  220 , a total of three scan electrodes  34  (that is, Yn, Yn+1, and Yn+2) correspond to all rows of pixels  220  shown in the drawing. The same as the scan electrodes  34 , a total of three sustain electrodes  32  (that is, Xn, Xn+1, and Xn+2) correspond to all rows of pixels  220  shown in the drawing.  
         [0054]     In such an arrangement of pixels, adjacent subpixels (for example, referring to the subpixels indicated by the reference numerals  220 G,  220 B) on the same address electrode  15  have phosphor layers of different colors. In such a way, subpixels having phosphor layers of the three different colors may be alternately arranged on the same address electrode  15 .  
         [0055]     In comparison with the conventional PDPs shown in  FIG. 5  and  FIG. 6 , only eight address electrodes are required to drive sixteen pixels arranged in a matrix pattern of 4×4 according to the present exemplary embodiment, while a total of twelve address electrodes are required to drive sixteen pixels arranged in a conventional matrix pattern. Therefore, the number of address electrodes required to drive the same number of pixels may be reduced.  
         [0056]      FIG. 4  is a top plan view partially showing an arrangement of pixels and electrodes of a PDP according to a third exemplary embodiment of the present invention.  
         [0057]     As shown in the drawing, according to the present exemplary embodiment, plan shapes of discharge cells  38  of the respective subpixels  320 R,  320 G,  320 B are formed in a generally rectangular shape. In addition, centers of the subpixels  320 R,  320 G,  320 B are arranged in a right triangular pattern. Therefore, two subpixels among the three subpixels  320 R,  320 G,  320 B are adjacently arranged along the elongation direction of an address electrode  15 , and two subpixels thereamong are adjacently arranged along the direction crossing the address electrode  15 .  
         [0058]     As seen in  FIG. 4 , according to the present exemplary embodiment, two address electrodes  15  correspond to each pixel  320 . Here, each pixel  320  includes the three subpixels  320 R,  320 G,  320 B of red, green, and blue colors. For each pixel  320 , at least two of the subpixels  320 R,  320 G,  320 B are driven by the same address electrode  15 .  
         [0059]     Scan electrodes  134  among display electrodes  135  are formed along borderlines between pairs of adjacent discharge cells  38 , and the scan electrodes  134  apply a common voltage to the pairs of adjacent discharge cells  38 . In the same way, sustain electrodes  132  among the display electrodes  135  are formed along borderlines between pairs of adjacent discharge cells  38 , and the sustain electrodes  132  apply a common voltage to the pairs of adjacent discharge cells  38 . Therefore, the scan electrodes  134  and the sustain electrodes  132  are alternately disposed along the elongation direction of the address electrode  15 , and each of them controls the discharge of the pairs of discharge cells  38 .  
         [0060]     For a scan electrode passing through the pixels  320 , three of four protruding transparent electrodes  134   b  lie within each pixel  320 . That is, since each pixel  320  includes three subpixels, two protruding transparent electrodes  134   b  lying on the borderline between two subpixels and one protruding transparent electrode  134   b  lying on a boundary of the other subpixel lie within the pixel  320 . Therefore, it may be regarded that ¾ of a scan electrode  134  corresponds to each pixel  320 . Therefore, according to the present exemplary embodiment, the number of address electrodes  15  and scan electrodes  134  required for driving the PDP satisfies a ratio shown in the above Equation 1, the same as in the first exemplary embodiment.  
         [0061]     In the exemplary arrangement shown in  FIG. 4 , a total of sixteen pixels  320  are arranged in the partial view, since four columns of pixels  320  are arranged in the horizontal direction and four rows of pixels  320  are arranged in the vertical direction. Since two address electrodes  15  correspond to each column of pixels  320 , a total of eight address electrodes  15  (that is, Am to Am+7) correspond to all columns of pixels  320  shown in the drawing. In addition, since ¾ of a scan electrode  134  corresponds to each row of pixels  320 , a total of three scan electrodes  134  (that is, Yn, Yn+1, and Yn+2) correspond to all rows of pixels  320  shown in the drawing. The same as the scan electrodes  134 , a total of three sustain electrodes  132  (that is, Xn, Xn+1, and Xn+2) correspond to all rows of pixels  320  shown in the drawing.  
         [0062]     In such an arrangement of pixels, adjacent subpixels (for example, refer to the subpixels indicated by the reference numerals  320 G,  320 B) on the same address electrode  15  have phosphor layers of different colors. In such a way, subpixels having phosphor layers of the three different colors may be alternately arranged on the same address electrode  15 .  
         [0063]     In comparison with the conventional PDPs shown in  FIG. 5  and  FIG. 6 , only eight address electrodes are required to drive sixteen pixels arranged in a matrix pattern of 4×4 according to the present exemplary embodiment, while a total of twelve address electrodes are required to drive sixteen pixels arranged in a conventional matrix pattern. Therefore, the number of address electrodes required to drive the same number of pixels may be reduced.  
         [0064]     In the following Table 1, the number of required address electrode terminals, power consumption, etc., are compared between a PDP according to an exemplary embodiment of the present invention and a PDP according to several comparative examples.  
         [0065]     Exemplary Embodiment 1 denotes a PDP of a dual driving scheme having a resolution of 1920×1080 (FHD resolution) according to an exemplary embodiment of the present invention. Comparative Example 1 denotes a PDP of a dual driving scheme having a stripe arrangement of subpixels and achieving the resolution of 1920×1080 (FHD resolution). Comparative Example 2 denotes a PDP of a dual driving scheme having a delta arrangement of subpixels and achieving the resolution of 1920×1080 (FHD resolution). Comparative Example 3 denotes a PDP of a dual driving scheme having a stripe (or delta) arrangement of subpixels and achieving the resolution of 1920×1080 (FHD resolution). Comparative Example 4 denotes a PDP of a dual driving scheme having a stripe (or delta) arrangement of subpixels and achieving a resolution of 1366×768. Comparative Example 5 denotes a PDP of a dual driving scheme having a stripe (or delta) arrangement of subpixels and achieving a resolution of 1280×720.  
         [0066]     In the following Table 1, address electrode power consumption, heat per address electrode circuit, and peak power per address electrode circuit are shown in relative values in comparison with values of Comparative Example 4.

         [0067]     As shown in Table 1, when a PDP has the resolution of 1920×1080 (refer to Comparative Examples 1 to 3), the number of address electrodes is required to be 5760. When the numbers of address electrode terminals and scan lines increase, address power consumption accordingly increases. In addition, power consumption also increases since crosstalk and stray capacitance increases due to a shortening of the distance between adjacent discharge cells.  
         [0068]     However, referring to Exemplary Embodiment 1 having the resolution of 1920×1080, the number of address electrode terminals thereof is substantially reduced to 3840. Therefore, as shown in Table 1, the PDP of Exemplary Embodiment 1 consumes less address power, generates less heat per address circuit, and has less peak power per address circuit than the PDPs of comparative examples having the same resolution.  
         [0069]     While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
