Detailed implementation manners

[0027] In order to better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] It should be clear that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "the" and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0030] It should be understood that the term " / and" used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0031] It should be understood that although the terms first, second, third, etc. may be used to describe sub-pixels in the embodiments of the present invention, these sub-pixels should not be limited to these terms. These terms are only used to distinguish sub-pixels that emit light of different colors from each other. For example, without departing from the scope of the embodiments of the present invention, the first sub-pixel may also be referred to as the second sub-pixel, and similarly, the second sub-pixel may also be referred to as the first sub-pixel.

[0032] The embodiments of the present invention provide a display panel, as Figure 1 shown Figure 1Schematic diagram of a display panel provided by an embodiment of the present invention. The display panel includes a first display area AA1 and a second display area AA2. Exemplarily, the second display area AA2 can partially surround the first display area AA1. The first display area AA1 is an optical device setting area where an optical device is correspondingly arranged. The orthographic projection of the optical device on the plane where the display panel is located is located in the first display area AA1. With such a setting, there is no need to additionally set space for the optical device in the display panel. As Figure 1 shown, the first display area AA1 includes a plurality of first pixel units 1 arranged in an array, and the second display area AA2 includes a plurality of second pixel units 2 arranged in an array. When the display panel is displaying, both the first display area AA1 and the second display area AA2 are used for display, which can enable the display panel to achieve a full-screen display effect during display. Exemplarily, the optical device includes a camera, a fingerprint sensor, etc. The optical device can be arranged on the side of the display panel away from the light-emitting side. In the embodiment of the present invention, the light transmittance of the first display area AA1 is greater than or equal to the light transmittance of the second display area AA2.

[0033] As Figure 2 shown, Figure 2 Magnified schematic diagram of the first display area of a display panel provided by an embodiment of the present invention. The first pixel unit 1 includes at least two sub-pixels 10. Figure 2 Taking the first pixel unit 1 including three sub-pixels 10 as an example. In the embodiment of the present invention, at least part of the edges of at least part of the sub-pixels 10 in the first pixel unit 1 are non-linear. Wherein, the shape of the edge of the sub-pixel 10 refers to the shape of the edge of the orthographic projection of the sub-pixel 10 on the plane where the display panel is located.

[0034] The optical device correspondingly arranged in the first display area AA1 needs to collect the light incident from the outside for imaging during operation. During the process of the outside light entering the optical device through the display panel, it will pass through various film layers in the display panel. In the related art, due to the blocking of light by the sub-pixels 10 and the array pattern formed by the periodic arrangement of the sub-pixels 10, the light will diffract after passing through the multiple sub-pixels 10 in the first display area AA1, resulting in the light obtained by the optical device correspondingly arranged in the first display area AA1 being affected, and then affecting the imaging effect of the optical device.

[0035] For the display panel provided by the embodiment of the present invention, by setting the shape of at least part of the edges of at least part of the sub-pixels 10 in the first display area AA1 to be non-linear, the non-linear edges can serve as diffraction suppression components to destroy the diffraction conditions. During the process of the outside light passing through the display panel and reaching the optical device, it is possible to avoid the formation of an obvious diffraction pattern after the light passes through the first display area AA1, so that the light received by the optical device correspondingly arranged in the first display area AA1 is more conducive to imaging, thereby improving the imaging effect of the optical device.

[0036] Exemplarily, as Figure 1 shown, the density of the first pixel unit 1 is less than that of the second pixel unit 2. With such a setting, the light transmittance of the first display area AA1 can be greater than that of the second display area AA2, which is beneficial to the imaging effect of the optical device subsequently provided corresponding to the first display area AA1.

[0037] Optionally, the above non-linear shape includes a broken line shape and / or an arc shape. Exemplarily, the number of broken lines or arcs included in the edge of the sub-pixel 10 can be multiple segments. When the edge of the sub-pixel 10 is set to include multiple segments of broken lines, as Figure 3 shown, Figure 3 is a schematic diagram of the sub-pixel of the first display area of another display panel provided by an embodiment of the present invention. The embodiment of the present invention can make the edge of the sub-pixel 10 form a serrated shape. When the edge of the sub-pixel 10 is set to include multiple segments of arcs, as Figure 4 shown, Figure 4 is a schematic diagram of the sub-pixel of the first display area of yet another display panel provided by an embodiment of the present invention. The embodiment of the present invention can make the edge of the sub-pixel 10 form a wavy shape.

[0038] Exemplarily, the embodiment of the present invention can set the shape of the sub-pixel 10 to include an ellipse.

[0039] Specifically, the above sub-pixel 10 includes a light-emitting element. As Figure 5 shown, Figure 5 is a schematic cross-sectional view of the first display area of a display panel provided by an embodiment of the present invention. The light-emitting element 30 includes a first electrode 101, a light-emitting layer 100, and a second electrode 102 which are stacked. Among them, the light-emitting layer 100 is located between the first electrode 101 and the second electrode 102. Exemplarily, the first electrode 101 is located on the side of the light-emitting layer 100 close to the substrate 20, and the second electrode 102 is located on the side of the light-emitting layer 100 away from the substrate 20. When the display panel is displaying, the driving circuit applies voltages to the first electrode 101 and the second electrode 102 respectively, so that holes and electrons move from the first electrode 101 and the second electrode 102 to the light-emitting layer 100 respectively. The holes and electrons recombine in the light-emitting layer 100 to generate excitons, and the excitons transition from the excited state to the ground state to radiate energy, causing the light-emitting layer 100 to emit light of a corresponding color. Optionally, the material of the above light-emitting layer 100 includes any one of organic light-emitting materials, inorganic light-emitting materials, and quantum dot light-emitting materials.

[0040] In an embodiment of the present invention, the light transmittance of the first electrode 101 is different from that of the second electrode 102, so that the light emitted by the light-emitting layer 100 is reflected multiple times between the first electrode 101 and the second electrode 102 to produce a microcavity effect. Exemplarily, the light transmittance of the first electrode 101 is less than or equal to that of the second electrode 102.

[0041] In an embodiment of the present invention, at least part of the edges of at least part of the first electrodes 101 in the first pixel unit 1 are non-linear in shape. In the embodiment of the present invention, by setting the shape of at least part of the edges of the first electrodes 101 with lower light transmittance in the first display area AA1 to be non-linear, when external light irradiates the optical device located on the side of the display panel away from the light-emitting side through the display panel, when the light passes through the first electrode 101, the non-linear edges of the first electrode 101 can serve as diffraction suppression components, which can prevent obvious diffraction patterns from being formed after the light passes through the first electrode 101, and is beneficial to improving the imaging effect of the optical device.

[0042] Exemplarily, as Figure 5 shown, the sub-pixel 10 further includes a pixel driving circuit 3, and the pixel driving circuit 3 is electrically connected to the light-emitting element 30. The pixel driving circuit 3 includes a thin-film transistor and a storage capacitor ( Figure 5 not shown). Figure 5 In the cross-sectional view shown, one thin-film transistor directly connected to the light-emitting element 30 is used as an illustration.

[0043] It should be noted that Figure 5 the position of the pixel driving circuit 3 shown is only an illustration. In the design of the display panel, the position of the pixel driving circuit 3 can be adjusted according to the requirements of the light transmittance of the first display area AA1. For example, the pixel driving circuit 3 can be arranged in the second display area AA2 to further improve the light transmittance of the first display area AA1.

[0044] Optionally, as Figure 5 shown, the sub-pixel 10 further includes a color filter 200; the color filter 200 is located on the side of the light-emitting layer 100 close to the light-emitting side of the display panel. Exemplarily, the orthographic projection of the color filter 200 on the plane of the display panel covers the light-emitting layer 100. For the overlapping light-emitting layer 100 and color filter 200, the colors of the two can be the same. Or, the colors of the two can also be different. For example, if the light emitted by the light-emitting layer 100 is white light, the color filter 200 can be set as any one of a red color filter, a green color filter, and a blue color filter according to the required color of the sub-pixel 10.

[0045] When the display panel is displaying, the light emitted by the light-emitting layer 100 can be emitted through the color filter 200, improving the light emission color purity of the sub-pixel 10. In addition, in the embodiments of the present invention, after the ambient light is incident on the color filter 200, the color filter 200 can filter the light in the ambient light that is different from its own color, thereby reducing the amount of ambient light incident into the display panel, and further reducing the amount of ambient light reflected by the film layers with reflection characteristics in the display panel, such as metal electrodes, to the human eye, achieving the effect of reducing the reflectivity of the display panel. Moreover, compared with the conventional display panel that uses a polarizer assembly to achieve the anti-reflection function, the color filter has a small thickness and low cost, which is beneficial to thinning the thickness of the display panel and reducing the cost of the display panel.

[0046] The color filter 200 only allows light of a specific wavelength band to pass through, and has a low transmittance for the remaining light. The ambient light is a composite light including multiple wavelength bands. After the ambient light is incident on the color filter 200, the intensity of the light passing through the color filter 200 will also become lower. In the embodiments of the present invention, by setting the shape of at least part of the edge of the color filter 200 to be non-linear, when the light passes through the color filter 200, the non-linear edge of the color filter 200 can serve as a diffraction suppression component, which can avoid the formation of obvious diffraction patterns after the light passes through the color filter 200, and is beneficial to improving the imaging effect of the optical device.

[0047] Exemplarily, when the first electrode 101 and the color filter 200 are simultaneously provided in the sub-pixel 10, the embodiments of the present invention can make the shape of part of the edge of the first electrode 101 or part of the edge of the color filter 200 non-linear. Or, the embodiments of the present invention can also simultaneously adjust the shapes of the first electrode 101 and the color filter 200 so that the shapes of part of the edge of the first electrode 101 and part of the edge of the color filter 200 are both non-linear.

[0048] Such as Figure 6 and Figure 7 shown, Figure 6 and Figure 7 are top view schematic diagrams of the sub-pixels in the first display area of two other display panels provided by the embodiments of the present invention. Among them, it is shown by taking the shape of part of the edge of the first electrode 101 and all the edges of the color filter 200 as non-linear.

[0049] Exemplarily, when the first electrode 101 and the color filter 200 are simultaneously provided in the sub-pixel 10, for the same sub-pixel 10, the embodiments of the present invention can make the shapes of the first electrode 101 and the color filter 200 different.

[0050] Such as Figure 6As shown, the edge of the first electrode 101 includes a straight edge S1 and an arc edge S2, and two adjacent straight edges S1 are connected by an arc edge S2. The shape of the color resistor 200 is oval. In the process of external light irradiating the optical device located on the back side of the display panel, the external light first passes through the color resistor 200 and then passes through the first electrode 101. Since the shapes of the color resistor 200 and the first electrode 101 are different, the color resistor 200 and the first electrode 101 will have two different effects on the light successively, which can further avoid the formation of obvious diffraction patterns after the light passes through the sub-pixel 10, and is beneficial to ensuring the imaging effect of the optical device.

[0051] In another implementable manner, the embodiments of the present invention can also set the shapes of the first electrode 101 and the color resistor 200 in the sub-pixel 10 to be the same. For example, as Figure 7 shown, the embodiments of the present invention can set the shapes of both to be oval. Among them, the area of the first electrode 101 is smaller than the area of the color resistor 200, and along the direction perpendicular to the plane where the display panel is located, the color resistor 200 covers the first color resistor 101.

[0052] Alternatively, the embodiments of the present invention can set the shape of one of the first electrode 101 and the color resistor 200 to be circular and the shape of the other to be quadrilateral. As Figure 8 and Figure 9 shown, Figure 8 and Figure 9 are schematic diagrams of the first electrode and the color resistor of the first sub-pixel provided by the embodiments of the present invention. In Figure 8 , the shape of the first electrode 101 is quadrilateral and the shape of the color resistor 200 is oval. In Figure 9 , the shape of the first electrode 101 is oval and the shape of the color resistor 200 is quadrilateral. In the process of external light irradiating the optical device located on the back side of the display panel, the color resistor 200 and the first electrode 101 will have two different effects on the light successively. The differential setting of the shapes of the first electrode 101 and the color resistor 200 can further avoid the formation of obvious diffraction patterns after the light passes through the sub-pixel 10, and is beneficial to ensuring the imaging effect of the optical device.

[0053] Exemplarily, in the embodiments of the present invention, as Figure 2 shown, multiple sub-pixels 10 in the first display area AA1 at least include a first sub-pixel 11 and a second sub-pixel 12, and the light emitting colors of the first sub-pixel 11 and the second sub-pixel 12 are different. In the embodiments of the present invention, the area of the second sub-pixel 12 is greater than or equal to the area of the first sub-pixel 11. For example, the first sub-pixel 11 includes a red sub-pixel that emits red light or a green sub-pixel that emits green light. The second sub-pixel 12 includes a blue sub-pixel that emits blue light.

[0054] AsFigure 10 As shown Figure 10 This is a top view schematic diagram of color filters of a first pixel unit provided by an embodiment of the present invention. The color filter 200 of the second sub-pixel 12 at least includes a first pattern 201 and a second pattern 202. Along the direction perpendicular to the plane where the display panel is located, the geometric centers of the first pattern 201 and the second pattern 202 are staggered from each other.

[0055] When setting the first pattern 201 and the second pattern 202, as Figure 10 shown, the embodiment of the present invention can make the first pattern 201 and the second pattern 202 have a certain distance therebetween. Or, as Figure 11 shown Figure 11 This is another top view schematic diagram of color filters of a first pixel unit provided by an embodiment of the present invention. The embodiment of the present invention can also make there be no gap between the first pattern 201 and the second pattern 202, that is, make the first pattern 201 and the second pattern 202 contact each other.

[0056] Compared with the case where the color filter 200 of the second sub-pixel 12 is set as one pattern, by setting the color filter 200 of the second sub-pixel 12 to at least include the first pattern 201 and the second pattern 202 and making the geometric centers of the first pattern 201 and the second pattern 202 stagger from each other, the embodiment of the present invention can make the color filter 200 of the second sub-pixel 12 form more patterns with smaller areas. Correspondingly, the number of edges of the color filter 200 of the second sub-pixel 12 can be set to be more. With such a setting, it is more conducive to making the shape of the color filter 200 in the second sub-pixel 12 irregular. After the external ambient light passes through the color filter 200, it is conducive to further weakening the formation of diffraction patterns so as to improve the imaging effect of the optical device.

[0057] And / or, as Figure 12 shown Figure 12 This is a top view schematic diagram of first electrodes of a first pixel unit provided by an embodiment of the present invention. The first electrode 101 in the second sub-pixel 12 at least includes a third pattern 203 and a fourth pattern 204. Along the direction perpendicular to the plane where the display panel is located, the geometric centers of the third pattern 203 and the fourth pattern 204 are staggered from each other.

[0058] When setting the third pattern 203 and the fourth pattern 204, as Figure 12 shown, the embodiment of the present invention can make the third pattern 203 and the fourth pattern 204 have a certain distance therebetween. Or, as Figure 13 shown Figure 13 This is another top view schematic diagram of first electrodes of a first pixel unit provided by an embodiment of the present invention. The embodiment of the present invention can also make the third pattern 203 and the fourth pattern 204 contact each other.

[0059] Compared with the case where the first electrode 101 of the second sub-pixel 12 is set to a single pattern, in the embodiments of the present invention, by setting the first electrode 101 of the second sub-pixel 12 to include at least a third pattern 203 and a fourth pattern 204, and staggering the geometric centers of the third pattern 203 and the fourth pattern 204 from each other, the first electrode 101 of the second sub-pixel 12 can form a larger number of patterns with smaller areas. Correspondingly, the number of edges of the first electrode 101 of the second sub-pixel 12 can be set to be larger. With such a setting, it is more conducive to making the shape of the first electrode 101 in the second sub-pixel 12 irregular. After the external ambient light passes through the first electrode 101, it is beneficial to further weaken the formation of diffraction patterns, so as to improve the imaging effect of the optical device.

[0060] As Figure 12 shown, when the third pattern 203 and the fourth pattern 204 are spaced apart by a certain distance, that is, when the third pattern 203 and the fourth pattern 204 do not touch each other, in the embodiments of the present invention, the two can be connected to the same pixel driving circuit. When the second display area AA2 is used for display, the third pattern 203 and the fourth pattern 204 receive the same signal and jointly drive the light-emitting elements located in the second display area AA2 to light up.

[0061] Exemplarily, as Figure 14 shown, Figure 14 is a schematic diagram of another first pixel unit provided by the embodiments of the present invention. The color resist in the second sub-pixel 12 includes a first pattern 201 and a second pattern 202, and at least one of the first pattern 201 and the second pattern 202 has a circular shape; Figure 14 For the sake of illustration, let the shapes of both the first pattern 201 and the second pattern 202 be circular, and their radii are both r. The shape of the first electrode 101 of the second sub-pixel 12 is quadrilateral. Along the direction perpendicular to the plane of the display panel, the center O1 of the circle corresponding to the first pattern 201 of the second sub-pixel 12 is located within the quadrilateral of the first electrode 101 of the second sub-pixel 12, and the center O2 of the circle corresponding to the second pattern 202 of the second sub-pixel 12 is located within the quadrilateral of the first electrode 101 of the second sub-pixel 12.

[0062] In an embodiment of the present invention, the radius of the circle of the first pattern 201 corresponding to the first sub-pixel 11 is r, the radius of the circle of the second pattern 202 corresponding to the second sub-pixel 12 is r, and the quadrilateral of the first electrode 101 corresponding to the second sub-pixel 12 has two intersecting sides, and the side lengths of the two intersecting sides are a and b respectively. The distance from the center O1 of the circle of the first pattern 201 corresponding to the first sub-pixel 11 to at least two corners of the quadrilateral of the first electrode 101 corresponding to the second sub-pixel 12 is equal. The distance from the center O2 of the circle of the second pattern 202 corresponding to the second sub-pixel 12 to at least two corners of the quadrilateral of the first electrode 101 corresponding to the second sub-pixel 12 is equal. As Figure 14 shown, the quadrilateral includes a first angle A and a second angle B. The distance from the center O1 to the first angle A and the second angle B is equal. The distance from the center O2 to the first angle A and the second angle B is equal. In an embodiment of the present invention, a < 2r < b < 4r. With such a setting, while weakening the diffraction pattern generated by the external ambient light passing through the second sub-pixel 12, the area coverage rate of the color resistor 200 of the second sub-pixel 12 on the first electrode 101 can also be increased. Correspondingly, the area coverage rate of the color resistor 200 of the second sub-pixel 12 on the light-emitting layer 100 can be increased, and the situation where the light emitted by the light-emitting layer 100 directly exits without passing through the color resistor 200 can be avoided.

[0063] Exemplarily, as Figure 2 shown, the plurality of sub-pixels 10 further includes at least a third sub-pixel 13, and the area of the second sub-pixel 12 is greater than or equal to the area of the third sub-pixel 13. Combining Figure 15 shown, Figure 15 is a schematic diagram of another first pixel unit provided by an embodiment of the present invention. The color resistor 200 in the second sub-pixel 12 includes a first pattern 201 and a second pattern 202, and the first electrode 101 in the second sub-pixel 12 includes a third pattern 203 and a fourth pattern 204. Along the direction perpendicular to the plane of the display panel, the geometric centers of the first pattern 201 and the third pattern 203 coincide, and the geometric centers of the second pattern 202 and the fourth pattern 204 coincide. Among them, the first pattern 201 and the second pattern 202 are arranged along a first direction h1; the first sub-pixel 11 and the third sub-pixel 13 are arranged along a second direction h2, and the first direction h1 and the second direction h2 intersect. With such a setting, the first pattern 201 and the second pattern 202 included in the color resistor 200 of the second sub-pixel 12 can be arranged as scattered as possible, and the third pattern 203 and the fourth pattern 204 included in the first electrode 101 of the second sub-pixel 12 can be arranged as scattered as possible. By adopting this setting method, on the one hand, the light emitted by the second sub-pixel 12 can be more evenly distributed in the area where the pixel unit 1 is located, and on the other hand, the second sub-pixel 12 can have a larger design space, which is beneficial to increasing the aperture ratio of the second sub-pixel 12.

[0064] Exemplarily, as Figure 2 shown, among the multiple sub-pixels 10 in the first pixel unit 1, there is at least a third sub-pixel 13, and the area of the second sub-pixel 12 is greater than or equal to the area of the third sub-pixel 13. As Figure 2 shown, along the third direction h3, the first sub-pixel 11 and the second sub-pixel 12 at least partially overlap, and the third sub-pixel 13 and the second sub-pixel 12 at least partially overlap. The first sub-pixel 11 and the third sub-pixel 13 are arranged along the fourth direction h4; the third direction h3 and the fourth direction h4 intersect.

[0065] Optionally, in the embodiments of the present invention, the shape and area of the first pattern 201 of the color resistor 200 of the second sub-pixel 12 can be made the same as the shape and area of the color resistor 200 of the first sub-pixel 11; and / or, the shape and area of the second pattern 202 of the color resistor 200 of the second sub-pixel 12 can be made the same as the shape and area of the color resistor 200 of the third sub-pixel 13; and / or, the shape and area of the third pattern 203 of the first electrode 101 of the second sub-pixel 12 can be made the same as the shape and area of the first electrode 101 of the first sub-pixel 11; and / or, the shape and area of the fourth pattern 204 of the first electrode 101 of the second sub-pixel 12 can be made the same as the shape and area of the first electrode 101 of the third sub-pixel 13. As Figure 16 and Figure 17 shown, Figure 16 and Figure 17 are schematic diagrams of two other first pixel units provided by the embodiments of the present invention. Among them, taking the area of the first pattern 201 included in the color resistor 200 of the second sub-pixel 12 being smaller than the area of the second pattern 202 as an illustration, in Figure 16 and Figure 17 the shape and area of the first pattern 201 of the color resistor 200 of the second sub-pixel 12 are the same as the shape and area of the color resistor 200 of the first sub-pixel 11; the shape and area of the second pattern 202 of the color resistor 200 of the second sub-pixel 12 are the same as the shape and area of the color resistor 200 of the third sub-pixel 13; the shape and area of the third pattern 203 of the first electrode 101 of the second sub-pixel 12 are the same as the shape and area of the first electrode 101 of the first sub-pixel 11; the shape and area of the fourth pattern 204 of the first electrode 101 of the second sub-pixel 12 are the same as the shape and area of the first electrode 101 of the third sub-pixel 13. With such a setting, the size difference between the color resistor 200 and the first electrode 101 of the second sub-pixel 12 and the color resistor or the first electrode of the first sub-pixel 11 or the third sub-pixel 13 can be reduced, which is beneficial to weakening the diffraction phenomenon.

[0066] It should be noted that the embodiments of the present invention do not limit the relative positional relationship between the first pattern 201 and the second pattern 202. For example, in Figure 16In [description], the arrangement directions of the first pattern 201 and the third sub-pixel 13 intersect with the arrangement directions of the second pattern 202 and the first sub-pixel 11. In Figure 17 In [description], the arrangement directions of the first pattern 201 and the third sub-pixel 13 are parallel to the arrangement directions of the second pattern 202 and the first sub-pixel 11.

[0067] An embodiment of the present invention further provides a display device, such as Figure 18 shown in Figure 18 is a schematic diagram of a display device provided by an embodiment of the present invention. The display device includes an optical device 300 and the above-mentioned display panel 1000; the orthographic projection of the optical device 300 on the plane where the display panel is located is located within the first display area AA1. Among them, the specific structure of the display panel 1000 has been described in detail in the above embodiments and will not be elaborated here. Of course, Figure 18 the display device shown is only for illustrative purposes, and the display device can be any electronic device with a display function, such as a mobile phone, a tablet computer, a notebook computer, an e-reader, or a television.

[0068] For the display device provided by the embodiment of the present invention, by setting the shape of at least part of the edges of some sub-pixels in the first display area of the display panel to be non-linear, the non-linear edges can serve as diffraction suppression components to destroy the diffraction conditions. During the process that external light is incident on the optical device through the display panel, it is possible to avoid the formation of obvious diffraction patterns after the light passes through the first display area, so that the light received by the optical device corresponding to the first display area is more conducive to imaging, thereby improving the imaging effect of the optical device.

[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
