Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In describing positional relationships, unless otherwise specified, when an element such as a layer, film or display substrate is referred to as being "on" another layer, it can be directly on the other layer or intervening layers may also be present. Further, when a layer is referred to as being "under" another layer, it can be directly under, or one or more intervening layers may also be present. It will also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or one or more intervening layers may also be present.

Where the terms "comprising," "having," and "including" are used herein, another element may be added unless an explicit limitation is used, such as "only," "consisting of … …," etc. Unless mentioned to the contrary, terms in the singular may include the plural and are not to be construed as being one in number.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention.

Fig. 1 shows a schematic structure diagram of a conventional Real pixel structure. The rectangular structures located inside in fig. 1 are a sub-pixel R, a sub-pixel G, and a sub-pixel B, and for convenience of description, the sides of the rectangular structures are referred to as the sides of the sub-pixels. The rectangular sides located outside the rectangular structure of the sub-pixels R, G, and B are referred to as reserved sides (i.e., Mask edges in the formation of a Mask process). The area between the pixel edge and the reserved edge constitutes the spacing area between the pixel openings. These large spacing regions, in turn, compress the display area of the pixel, resulting in a lower aperture ratio of the pixel.

As shown in fig. 1, the Real pixel structure is arranged with the pixels juxtaposed, and its PPI is always low.

In addition, as the flexible screen has the advantages of being bendable, light and thin, along with the development of the flexible screen, in order to enable the corners of the flexible screen to display soft feeling, prevent the corners of the screen from being damaged and improve the effects of holding and vision, the chamfer design of the flexible screen has become the future trend. However, the design of the chamfer is affected by the arrangement of the step pixels, and a jagged display effect generally appears at the chamfer, thereby reducing the picture quality.

In view of the above problems, the present invention provides a display panel and a pixel arrangement structure thereof to improve the PPI of the pixels of the display panel, thereby prolonging the service life of the display panel. In addition, the display effect of the display panel at the chamfer can be improved.

Fig. 2 is a schematic structural diagram illustrating a pixel arrangement structure of the display panel 10 according to an embodiment of the present invention.

Referring to fig. 2, a pixel arrangement structure of a display panel 10 according to an embodiment of the present invention includes a plurality of sub-pixel rows.

The respective sub-pixels in each sub-pixel row are arranged in a first direction 01, and the plurality of sub-pixel rows are arranged in a second direction 02 perpendicular to the first direction 01. Each sub-pixel is quadrilateral in shape, each sub-pixel comprises a first side and a second side which are adjacent, the first side of each sub-pixel is parallel to the first direction 01, the second side of each sub-pixel is obliquely arranged relative to the second direction 02, and the second direction 01 is perpendicular to the first direction 02.

In the plurality of sub-pixel rows, each adjacent two sub-pixel rows constitute one pixel group 10 a. In each pixel group 10a, the first subpixels 11 and the second subpixels 12 are arranged in one row in the first direction 01, and the third subpixels 13 are arranged in the other adjacent row in the first direction 01.

The sub-pixels adopted by the pixel arrangement structure are quadrilateral, for example, a rhombic structure is preferred, then the first sub-pixels 11 and the second sub-pixels 12 are arranged in one row in the first direction 01, the third sub-pixels 13 are arranged in the other adjacent row in the first direction 01, the first edges of the sub-pixels are parallel to the first direction, and the second edges are obliquely arranged relative to the second direction, so that the formed pixel arrangement structure avoids the problem that the PPI arranged in a pixel juxtaposition mode in the Real pixel structure is low, the step feeling and the sawtooth effect at the chamfer can be eliminated to a certain extent, the PPI of the display panel 10 is improved, and meanwhile, a good display effect can be obtained at the oblique and chamfer positions. In addition, the third sub-pixels 13 are separately arranged in a row, which is beneficial to the routing of the third sub-pixels 13.

It is understood that the pixel arrangement structure may be applied to the entire display area of the display panel 10, or may be disposed in a partial display area of the display panel 10, such as a chamfered area or an edge area. Specifically, the pixel arrangement structure favorable for oblique display is arranged in the chamfering area, and other different pixel arrangement structures are arranged in the middle area, so that a better display effect is achieved in the middle area, and the overall display effect of the display panel 10 is better.

Specifically, in the example shown in fig. 2, the second edge of each sub-pixel is inclined downward from the upper left to the lower right with respect to the second direction 02, and the pixel arrangement structure is particularly suitable for a chamfered region disposed at the upper right corner and/or the lower left corner of the display panel, which is beneficial to improving the oblique display effect of the chamfered region.

It is understood that in other examples, the second side of each sub-pixel is inclined from the lower left to the upper right with respect to the second direction 02, and the pixel arrangement structure is particularly suitable for the chamfered region disposed at the upper left corner and/or the lower right corner of the display panel, so as to improve the oblique display effect of the chamfered region. Namely: the edge extension direction of the chamfered region coincides with the inclination direction of the second edge of each sub-pixel.

In some embodiments, each third sub-pixel 13 is arranged to be offset from the adjacent first sub-pixel 11 and second sub-pixel 12 of the adjacent row. The first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 adjacent to each other form a pixel unit, each virtual light emitting center of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 forms a virtual triangle, when the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 emit white light together, the white light center is close to the center of the virtual triangle, and the white light emission is relatively uniform.

It is understood that, in other examples, each third sub-pixel 13 and the adjacent first sub-pixel 11 and second sub-pixel 12 of the adjacent row may also be arranged without being staggered, for example, each third sub-pixel 13 and the adjacent first sub-pixel 11 or second sub-pixel 12 of the adjacent row are located on the same row (or aligned) in the second direction 02.

In the example shown in fig. 2, within each pixel group 10, one first sub-pixel 11 and one second sub-pixel 12 are alternately arranged in a row in the first direction 01, and any adjacent one first sub-pixel 11 and one second sub-pixel 12 are misaligned and adjacent to one third sub-pixel 13. Thus, a first sub-pixel 11 and a second sub-pixel 12 in the same row and a third sub-pixel 13 adjacent to the offset can form a pixel unit (as shown by the dashed triangle in fig. 2), that is, each first sub-pixel 11 and each second sub-pixel 12 are shared for 2 times, and the third sub-pixel 13 is a real pixel, so that a higher resolution display effect can be simulated through pixel sharing, and the visual brightness is higher and the cost is lower under the same brightness. Further, the number ratio of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 is 1:1: 2.

With continued reference to fig. 2, each sub-pixel is shaped as a parallelogram, preferably, each sub-pixel is shaped as a diamond. The second sides of the sub-pixels in the same sub-pixel row are inclined in the same direction with respect to the second direction 02. Further, the second sides of the sub-pixels located in the same pixel group 10a are inclined in the same direction with respect to the second direction 02.

It is understood that, in some examples, the inclination directions of the second sides of the sub-pixels in the same pixel group 10a with respect to the second direction 02 may also be different, for example, the inclination directions of the second sides of the sub-pixels in two adjacent sub-pixel rows in the same pixel group 10a with respect to the second direction 02 are opposite. It is understood that, in some examples, the two rows of sub-pixels in the same pixel group 10 are not limited, and the second sides of the sub-pixels in any two adjacent rows of sub-pixels may be inclined in opposite directions with respect to the second direction 02.

It can be understood that each adjacent n sub-pixel rows in the plurality of sub-pixel rows may also be divided into a pixel group, the inclination directions of the second sides of the sub-pixels in each pixel group are the same, and the inclination directions of the second sides of the sub-pixels in two adjacent pixel groups are opposite; wherein n is any integer from 2 to 6.

The inclined arrangement means that the second edge forms an included angle with the second direction 02, and the included angle is not 90 degrees. The oblique direction means that if the first direction 01 and the second direction 02 form first to fourth quadrants and the second edge of each sub-pixel passes through the origin, the second edge is positioned at the same second edge of the first and third quadrants or at the same second edge of the second and fourth quadrants, and the oblique direction of the second edge with respect to the second direction 02 is the same. The tilt angle is the angle of the second edge with the second direction 02.

In one embodiment, the second edges of the sub-pixels in the same pixel group 10a are inclined at the same angle.

In the example shown in fig. 2, the arrangement of the respective sub-pixels of any two adjacent pixel groups 10a is the same. That is, the first sides of the sub-pixels of any two adjacent pixel groups 10a have the same inclination direction and inclination angle, and the first sub-pixels 11 and the second sub-pixels 12 in the odd-numbered or even-numbered rows have the same arrangement as the third sub-pixels 13 in the odd-numbered or even-numbered rows. Therefore, the step feeling and the sawtooth effect at the chamfer A can be further eliminated, and a better display effect can be obtained at the oblique direction and the chamfer A.

It is understood that, in some examples, there may be at least two adjacent pixel groups 10a with the same arrangement of the sub-pixels. That is, it is within the scope of the present invention that the arrangement of the sub-pixels including the two adjacent pixel groups 10a is the same.

In one embodiment, each third sub-pixel 13 in each pixel group 10a is located in an odd or even row. For example, the first sub-pixel 11 and the second sub-pixel 12 occupy even rows, and the third sub-pixel 13 occupies odd rows alone, which is equivalent to the two rows of sub-pixels being alternately arranged, so that a more uniform display effect can be obtained.

It is understood that in other embodiments, the two rows of the third sub-pixels 13 of the adjacent pixel group 10a may be adjacently disposed, as shown in fig. 5, and described in detail below. Further, since the third sub-pixels 13 are arranged in one row, a plurality of third sub-pixels 13 arranged in the same row can share one Mask opening during vapor deposition, thereby improving the aperture ratio. For example, two adjacent third sub-pixels share a Mask opening (as shown in fig. 6). It can be understood that the distance between the center points of the two adjacent third sub-pixels 13 sharing the Mask opening may be set to be smaller than the distance between the center points of the two adjacent third sub-pixels 13 not sharing the Mask opening in the same row, so that the design margin may be further reduced, and a higher aperture ratio may be obtained.

In one embodiment, the light emitting color of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 is selected from one of red, green and blue.

Preferably, in the first sub-pixel 11 and the second sub-pixel 12, one light emission color is red, one light emission color is blue, and the light emission color of the third sub-pixel 13 is green. Specifically, in this example, the emission color of the first sub-pixel 11 is red, and the emission color of the second sub-pixel 12 is blue. Specifically, in the present example, the area of the second sub-pixel 12 is larger than the area of the first sub-pixel 11, and is larger than the area of the third sub-pixel 13. Further, the area of the first sub-pixel 11 is larger than the area of the third sub-pixel 13. Therefore, the method can better adapt to pixels with different service lives and reduce the problem of color cast in vision.

It should be noted that: first, the first direction 01 and the second direction 02 are not limited to the first direction 01 being a column direction and the second direction 02 being a row direction as shown in fig. 2, but in other embodiments, the first direction 01 may be a row direction and the second direction 02 may be a column direction; second, the row described herein may be a column or a row that may be aligned with the first direction 01 and/or the second direction 02.

Fig. 3 is a schematic structural diagram illustrating a pixel arrangement structure of a display panel according to still another embodiment of the present invention. Referring to fig. 3, a pixel arrangement structure of the display panel 20 according to the first embodiment of the present invention is substantially the same as the pixel arrangement structure of the display panel 10 shown in fig. 2, except that: the arrangement of the sub-pixels of two adjacent pixel groups 20a is the same, but not exactly the same, and the specific difference is that the first sub-pixels 21 of any two adjacent pixel groups 20a are arranged in a staggered manner in the second direction 02, and the second sub-pixels 22 of the two adjacent pixel groups 20a are arranged in a staggered manner in the second direction 02; that is, in the second direction 02, the first sub-pixels 21 and the second sub-pixels 22 are also alternately disposed with each other. The arrangement of the third sub-pixels 23 remains the same as in fig. 2.

It is understood that in other examples, at least the first sub-pixels 21 of the two adjacent pixel groups 10a may be arranged in the second direction 02 in a staggered manner, and the second sub-pixels 22 of the two adjacent pixel groups 20a may be arranged in the second direction 02 in a staggered manner. That is, it is within the scope of the present invention that the second sub-pixels 22 of the two adjacent pixel groups 20a are arranged in the second direction 02, as long as the first sub-pixels 21 of the two adjacent pixel groups 10a are arranged in the second direction 02 in a staggered manner.

Fig. 4 is a schematic structural diagram illustrating a pixel arrangement structure of a display panel according to still another embodiment of the present invention. Referring to fig. 4, a pixel arrangement structure of a display panel 30 according to a first embodiment of the present invention is substantially the same as the pixel arrangement structure of the display panel 10 shown in fig. 2, except that: the second sides of the sub-pixels in two adjacent pixel groups 30a are inclined in opposite directions. Therefore, better display effects are obtained at the oblique positions and the chamfers, the display effects are better symmetrical relative to the first direction 01, and the sawtooth effect and the color edge effect can be reduced at the chamfers positioned at the two sides of the first direction 01, so that the better display effects are obtained; in addition, the stereoscopic display effect can be further improved.

Specifically, in two adjacent pixel groups 30a, the inclination direction of the second edge of the first sub-pixel 31, the second sub-pixel 32 and the third sub-pixel 33 of one pixel group 30a is opposite to the inclination direction of the second edge of the first sub-pixel 31, the second sub-pixel 32 and the third sub-pixel 33 of the other pixel group 30 a.

Further, although the second sides of the sub-pixels in the two adjacent pixel groups 30a are inclined in opposite directions, the inclination angles may be the same. Fig. 5 is a schematic structural diagram illustrating a pixel arrangement structure of a display panel according to still another embodiment of the present invention. Referring to fig. 5, a pixel arrangement structure of a display panel 40 according to a first embodiment of the present invention is substantially the same as the pixel arrangement structure of the display panel 10 shown in fig. 4, except that: two rows of the third sub-pixels 43 of every two adjacent pixel groups 40a are adjacently disposed. Thus, a higher pixel aperture ratio can be obtained for the third sub-pixel 43.

Specifically, with reference to one of the pixel groups 40a located at the middle position, two of the pixel groups 40a adjacent thereto are provided, which are disposed adjacent to the two rows of third sub-pixels 43 of one of the adjacent pixel groups 40a, and two sub-pixel rows formed by arranging the plurality of first sub-pixels and the plurality of second sub-pixels in the first direction are disposed between the two rows of third sub-pixels 43 of the other adjacent pixel group 40 a.

Further, the sub-pixels of each two adjacent pixel groups 40a are distributed in mirror symmetry with each other along the straight line where the first direction 01 is located. It is understood that in other embodiments, the two rows of the third sub-pixels 43 of each adjacent two pixel groups 40a are disposed adjacently, but the first sub-pixel 41, the second sub-pixel 42 and the third sub-pixel 43 of each adjacent two pixel groups 40a are not mirror symmetric but slightly shifted.

Fig. 6 is a schematic structural diagram illustrating a pixel arrangement structure of a display panel according to still another embodiment of the present invention. Referring to fig. 6, a pixel arrangement structure of a display panel 50 according to a first embodiment of the present invention is substantially the same as the pixel arrangement structure of the display panel 10 shown in fig. 2, except that: the differences as in fig. 3 and fig. 4 are combined. Namely, the difference is that:

the first sub-pixels 51 of two adjacent pixel groups 50a are arranged in a staggered manner in the second direction 02, and the second sub-pixels 52 of two adjacent pixel groups 50a are arranged in a staggered manner in the second direction 02, so that the first sub-pixels 51 and the second sub-pixels 52 are alternately arranged in the second direction 02; and the inclination directions of the second sides of the sub-pixels in the two adjacent pixel groups 50a are opposite. The arrangement of the third sub-pixel 53 remains the same as in fig. 2.

It is understood that, in the second direction 02, the center point of the first sub-pixel 51 and the center point of the second sub-pixel 52 may be located on the same straight line or not.

Further, the pixel arrangement of the display panel 50 shown in fig. 6 is also different from the pixel arrangement of the display panel 10 shown in fig. 2 in that Mask openings are shared: two adjacent third sub-pixels 13 in the same row share one Mask opening, so that the pixel aperture ratio is improved.

Fig. 7 is a schematic structural diagram illustrating a pixel arrangement structure of a display panel according to still another embodiment of the present invention. Referring to fig. 7, a pixel arrangement structure of a display panel 60 according to a first embodiment of the present invention is substantially the same as the pixel arrangement structure of the display panel 10 shown in fig. 6, except that: in each pixel group 60a, every two first sub-pixels 61 and every two second sub-pixels 62 are alternately arranged in a row in the first direction 01, and every adjacent one of the first sub-pixels 61 and one of the second sub-pixels 62 is offset and adjacent to one of the third sub-pixels 63.

Thus, each of the first sub-pixel 61, the second sub-pixel 62 and the third sub-pixel 63 is a real pixel, and one adjacent first sub-pixel 61 and one adjacent second sub-pixel 62 and one staggered adjacent third sub-pixel 63 form a pixel unit (as shown by a dotted triangle in fig. 7), so that a better display effect can be obtained on the basis of fig. 2 or fig. 5, the unreality caused by rendering due to pixel sharing is avoided, and the reality of display is improved. In the example shown in fig. 7, the number ratio of the first sub-pixel 61, the second sub-pixel 62 and the third sub-pixel 63 is 1:1: 1.

Specifically, in the examples shown in fig. 4 to 7, the pixel arrangement structure is applicable to the chamfered region of the display panel to meet the oblique display requirement of the chamfered region, and is also applicable to the entire display region disposed on the display panel, so that the uniform display effect of the display region including the chamfered region can be realized.

In the example shown in fig. 2, each sub-pixel is shaped as a non-rectangular parallelogram.

It is understood that in other examples, as shown in FIGS. 8-12, at least some of the sub-pixels may be trapezoidal in shape, such as right-angled trapezoids or isosceles trapezoids. Specifically, the first side of the sub-pixel is one of two bottom sides of the trapezoid, and the second side is a slant waist side of the trapezoid.

As shown in fig. 8 to 12, the sub-pixels in the same pixel group have a parallelogram shape and a trapezoid shape.

As shown in FIGS. 8-11, each sub-pixel has at least one second side having the same inclination direction relative to the second direction. As shown in fig. 12, each sub-pixel in the same pixel group has at least one second side with the same inclination direction relative to the second direction, and the inclination directions of the second sides of each sub-pixel in two adjacent pixel groups are opposite.

Referring to fig. 8, in particular, each of the first sub-pixels 71, the second sub-pixels 72, and the third sub-pixels 73 of the display panel 70 has a right trapezoid shape, one waist side of the right trapezoid is a straight waist side, and the other waist side is a slanted waist side. Wherein, the second limit is right trapezoid's oblique waist limit, and right trapezoid's straight waist limit is parallel with the second direction. Further, the inclination directions of the second sides of two adjacent sub-pixels in the same sub-pixel row are the same, and further, the inclination angles of the second sides of two adjacent sub-pixels in the same sub-pixel row are also the same, that is, the second sides of the two sub-pixels are parallel to each other.

Two straight waist edges or two oblique waist edges of two adjacent sub-pixels in the same sub-pixel row are adjacent to each other. Further, two oblique sides adjacent to each other of two adjacent sub-pixels in the same sub-pixel row are parallel to each other.

In the example shown in fig. 8, each sub-pixel has a second side (a waist side) with the same inclination direction relative to the second direction 02, so that when the second side of each sub-pixel is inclined from the upper left to the lower right relative to the second direction 02, the pixel arrangement structure is distributed in the chamfered region at the upper right corner and/or the lower left corner of the display region; the second side of each sub-pixel is inclined from the lower left side to the upper right side relative to the second direction 02, and the pixel arrangement structure is distributed in the chamfered area at the upper left corner and/or the lower right corner of the display area.

Referring to fig. 9, in particular, the first sub-pixel 81, the second sub-pixel 82 and the third sub-pixel 83 of the display panel 80 are shaped as isosceles trapezoids, and two oblique sides of two adjacent sub-pixels in the same sub-pixel row are adjacent to each other. Further, two oblique sides adjacent to each other of two adjacent sub-pixels in the same sub-pixel row are parallel to each other.

In the example shown in fig. 9, each sub-pixel has two second sides with the same inclination direction with respect to the second direction 02, so that the pixel arrangement structure is distributed in any one of the chamfered regions of the display region, and is also applicable to the whole display region.

Fig. 10 and fig. 11 respectively show a schematic structural diagram of a pixel arrangement structure of a display panel according to still another embodiment of the present invention, which is different from fig. 8 in that a sub-pixel portion of the display panel is a trapezoid, and a portion of the sub-pixel is a parallelogram.

Specifically, in the display panel 90 shown in fig. 10, each of the first sub-pixels 91 and each of the second sub-pixels 92 has a right-angled trapezoid shape; and each third sub-pixel 93 has a rhomboid-like parallelogram shape.

Specifically, in the display panel 100 shown in fig. 11, each of the first sub-pixels 101 and each of the second sub-pixels 102 has an isosceles trapezoid shape; and each third sub-pixel 93 has a rhomboid-like parallelogram shape.

In the example shown in fig. 10 or 11, part of the sub-pixels are in a shape of a parallelogram, and part of the sub-pixels are in a shape of a right trapezoid or an isosceles trapezoid. The sub-pixel in the shape of a parallelogram has two sides which are obliquely arranged relative to the second direction, wherein one side is the second side.

The right trapezoid or the isosceles trapezoid is provided with a first side and a second side which are adjacent, the first side is parallel to the first direction, and the second side is obliquely arranged relative to the second direction. And each sub-pixel has a second side inclined in the same direction relative to the second direction.

Please refer to fig. 12, which is substantially the same as fig. 11, for example: the first subpixel 111 and the second subpixel 112 have an isosceles trapezoid shape, and the third subpixel 113 has a parallelogram shape. Each sub-pixel in the same pixel group 110a has at least one second side having the same inclination direction with respect to the second direction 02.

The difference from fig. 11 is that: the second sides 02 of the sub-pixels in two adjacent pixel groups 110a are inclined in opposite directions. The pixel arrangement structure is distributed in any chamfer area of the display area; preferably, the pixel arrangement is distributed over the entire display area.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

For example, in the example shown in fig. 7, the third sub-pixels 63 within each pixel group 60a are each located in an odd-numbered row or are each located in an even-numbered row; it can be understood that it can also be combined with the above technical feature "two rows of third sub-pixels adjacent in two adjacent pixel groups" to obtain a new technical solution. For another example, in the example shown in fig. 7, the arrangement of the sub-pixels in each pixel group 60a is the same or not the same, that is, the first sub-pixels 61 of two adjacent pixel groups 60a are arranged in a staggered manner in the second direction 02, and the second sub-pixels 62 of two adjacent pixel groups 60a are arranged in a staggered manner in the second direction 02; it is understood that the new technical solution can also be obtained by combining the above technical features "the same arrangement of the sub-pixels of the two adjacent pixel groups". For example, in the examples shown in fig. 8 or fig. 9, the new technical solution can be obtained by combining the above other technical features. Others are not to be taken as an example.

Based on the same inventive concept, the embodiment of the invention also provides a display device, which comprises the display panel in the embodiment.

The display device can be any product or component with a fingerprint identification function, such as a mobile phone, a tablet personal computer, a television, a display, a notebook computer, a digital photo frame, a vehicle-mounted device, a wearable device or an internet of things device.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
