[0004] The technical solutions provided by the embodiments of the present disclosure are as follows:

[0005] An embodiment of the present disclosure provides a pixel arrangement structure, comprising a first pixel repeating unit and a second pixel repeating unit alternately arranged along a row direction, wherein the first pixel repeating unit and the second pixel repeating unit each include a first sub-pixel, a second sub-pixel, and a third sub-pixel displaying different colors;

[0006] In the first pixel repeating unit, centers of the first sub-pixel, the second sub-pixel, and the third sub-pixel are connected as vertices to form a first virtual triangle, and a first side of the first virtual triangle forms a preset angle with the row direction, the first side of the first virtual triangle is formed by connecting the centers of the first sub-pixel and the second sub-pixel, and the vertex opposite to the first side of the first virtual triangle is the center of the third sub-pixel;

[0007] In the second pixel repetition unit, the centers of the first sub-pixel, the second sub-pixel and the third sub-pixel are connected as vertices to form a second virtual triangle, and the first side of the second virtual triangle is perpendicular to the first side of the first virtual triangle. The first side of the second virtual triangle is formed by connecting the centers of the first sub-pixel and the second sub-pixel, and the vertex opposite to the first side of the second virtual triangle is the center of the third sub-pixel.

[0008] Exemplarily, the pixel pattern of the second pixel repeating unit is the same as the pixel pattern of the first pixel repeating unit that is rotated 90° clockwise or counterclockwise.

[0009] Exemplarily, in the same pixel row, the first pixel repeating unit and the first sub-pixel in the second pixel repeating unit adjacent to the first pixel repeating unit are adjacent, and the first sub-pixel in the first pixel repeating unit and the first sub-pixel in the second pixel repeating unit have the same width in the column direction, so that the light-emitting material layer of the first sub-pixel in the first pixel repeating unit and the first sub-pixel in the second pixel repeating unit can be formed by evaporation through the same pixel opening on the mask.

[0010] Illustratively, in the first pixel repeating unit and the second pixel repeating unit adjacently arranged in the row direction, a spacing in the row direction between two first sub-pixels of the same color is smaller than a spacing between any two adjacent sub-pixels of different colors.

[0016] Among them, in the first pixel column, at least two adjacent rows of first pixel repeating units are a group, and the third sub-pixels in the same group of pixel repeating units are adjacent and have the same width in the row direction, so that the light-emitting material layer of the third sub-pixels in the same group of pixel repeating units can be formed by evaporation through the same pixel opening on the mask.

[0017] Illustratively, the spacing between third sub-pixels in the same group of pixel repeating units in the column direction is smaller than the spacing between any two adjacent sub-pixels of different colors in the first pixel repeating unit and the second pixel repeating unit adjacently arranged in the row direction.

[0020] The opening areas of the red sub-pixel and the green sub-pixel are both smaller than the opening area of ​​the blue sub-pixel.

[0021] Exemplarily, the first virtual triangle and the second virtual triangle are both isosceles triangles, the line connecting the centers of the first sub-pixel and the third sub-pixel is one waist of the isosceles triangle, and the line connecting the centers of the second sub-pixel and the third sub-pixel is the other waist of the isosceles triangle.

The first side formed by the center lines of the first sub-pixel and the second sub-pixel in the first virtual triangle is at a predetermined angle (for example, 90°) to the row direction, and the first side formed by the center lines of the first sub-pixel and the second sub-pixel in the second virtual triangle is perpendicular to the first side of the first virtual triangle, and the first pixel repeating unit and the second pixel repeating unit are alternately arranged in the row direction.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0033] Before describing in detail the pixel arrangement structure and display device provided by the embodiments of the present disclosure, it is necessary to describe the related technologies as follows:

[0034] In related technologies, pixel arrangements for display products are primarily categorized into two types: the standard RGB arrangement, also known as Real RGB, and the Pentile arrangement, which uses pixel substitution to achieve white light display. While the Pentile arrangement can also achieve high PPI displays, it reduces the number of sub-pixels by sharing sub-pixels between adjacent pixels. This inevitably leads to issues such as "grids," "dark spots," "color fringing," and jagged edges. The standard RGB arrangement design, on the other hand, imposes technical barriers and limitations on the shape of each sub-pixel, the pixel arrangement and shape, and even the spacing between sub-pixels.

[0035] In order to break through such technical barriers and limitations, the embodiments of the present disclosure provide a novel pixel arrangement structure and a display device having the pixel arrangement structure, which can improve display effects and reduce production difficulty.

[0036] Figures 1 to 6 FIG. 1 is a schematic diagram of a pixel arrangement structure provided in some embodiments of the present disclosure. Figures 1 to 6 As shown, the pixel arrangement structure provided by the embodiment of the present disclosure includes: a first pixel repeating unit S1 and a second pixel repeating unit S2 alternately arranged along a row direction, wherein the first pixel repeating unit S1 and the second pixel repeating unit S2 each include a first sub-pixel 100, a second sub-pixel 200, and a third sub-pixel 300 displaying different colors; in the first pixel repeating unit S1, the centers of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 are connected as vertices to form a first virtual triangle A, and a first side of the first virtual triangle A forms a preset angle with the row direction, the first side is formed by connecting the centers of the first sub-pixel 100 and the second sub-pixel 200, and the vertex opposite to the first side is the center of the third sub-pixel 300, and the preset angle can be, for example, 90°±45°. Taking the preset angle of 90°±10 as an example, at this time, the first side of the first virtual triangle is perpendicular to the row direction;

[0037] In the second pixel repetition unit S2, the centers of the first sub-pixel 100, the second sub-pixel 200 and the third sub-pixel 300 are connected as vertices to form a second virtual triangle B, and the first side of the second virtual triangle B is perpendicular to the first side of the first virtual triangle A. The first side of the first virtual triangle is formed by connecting the centers of the first sub-pixel 100 and the second sub-pixel 200, and the vertex opposite to the first side is the center of the third sub-pixel 300.

[0038] In the above scheme, the pixel arrangement structure includes two pixel repeating units, a first pixel repeating unit S1 and a second pixel repeating unit S2. The two pixel repeating units correspond to two different sub-pixel arrangement modes, respectively. In the first pixel repeating unit S1, the center lines of the first sub-pixel 100, the second sub-pixel 200 and the third sub-pixel 300 form a first virtual triangle A. In the first pixel repeating unit S1, the center lines of the first sub-pixel 100, the second sub-pixel 200 and the third sub-pixel 300 form a second virtual triangle B. In the first virtual triangle A, the first side formed by the center line of the first sub-pixel 100 and the second sub-pixel 200 is at a preset angle to the row direction. In the second virtual triangle B, the first side formed by the center line of the first sub-pixel 100 and the second sub-pixel 200 is perpendicular to the first side of the first virtual triangle. In the row direction, the first pixel repeating unit S1 and the second pixel repeating unit S2 are alternately arranged.

[0039] It should be noted that, in the above solution, the first side of the first virtual triangle forms a preset angle with the row direction, and the preset angle may be, for example, 90°±45°. In this case, a line connecting a first position point in the first sub-pixel (the first position point includes but is not limited to the center of the first sub-pixel) and a second position point in the second sub-pixel (the second position point includes but is not limited to the center of the second sub-pixel) in the first virtual triangle is perpendicular to the row direction.

[0040] Correspondingly, the first side of the second virtual triangle is perpendicular to the first side of the first virtual triangle. The term "perpendicular" here refers to approximately perpendicular. For example, the angle between the first side of the second virtual triangle and the first side of the first virtual triangle is 90°±10°, which can be considered as approximately perpendicular. At this time, the line connecting the third position point in the first sub-pixel in the second virtual triangle (the third position point includes but is not limited to the center of the first sub-pixel) and the fourth position point in the second sub-pixel (the fourth position point includes but is not limited to the center of the second sub-pixel) is parallel to the row direction. The arrangement of the pixel arrangement structure in the embodiment of the present disclosure is a standard RGB arrangement. However, since it includes two pixel repeating units and the arrangement of the second pixel repeating unit S2 is different from that of the first pixel arrangement unit, in the pixel row direction, the arrangement of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 is both horizontal and vertical. In this way, each sub-pixel can also be shared between adjacent first pixel repeating units S1 and second pixel repeating units S2. Therefore, the pixel arrangement structure provided by the embodiment of the present disclosure combines the advantages of both the Real RBG arrangement and the Pentile arrangement, thereby effectively improving the display effect.

[0041] Therefore, the embodiments of the present disclosure provide a novel pixel arrangement structure that can overcome display problems caused by technical barriers of related pixel arrangement structures.

[0042] The following is a more detailed description of the embodiments of the present disclosure.

[0043] In some exemplary embodiments, Figures 1 to 3 As shown, the pixel pattern of the second pixel repeating unit S2 is the same as the pixel pattern of the first pixel repeating unit S1 which is rotated 90° clockwise or counterclockwise.

[0044] For example, Figure 1 As an example, the pixel pattern in the first pixel repeating unit S1 rotated 90° counterclockwise to obtain a pixel pattern that is completely consistent with the second pixel repeating unit S2; in other embodiments, such as Figure 2 As shown, the pixel pattern in the first pixel repeating unit S1 is rotated 90° clockwise to obtain a pixel pattern that is completely consistent with the pixel pattern in the second pixel repeating unit S2.

[0045] That is, in this exemplary embodiment, the sub-pixel arrangement structure of the first pixel repeating unit S1 rotated 90° as a whole is the same as the pixel arrangement pattern of the second pixel repeating unit S2. The size, shape and arrangement spacing between the sub-pixels in the first pixel repeating unit S1 and the second pixel repeating unit S2 are the same, and only the arrangement direction and arrangement position are different.

[0046] In addition, in this exemplary embodiment, the size, shape, and spacing of the first sub-pixel 100 , the second sub-pixel 200 , and the third sub-pixel 300 are not limited.

[0047] In this exemplary embodiment, the display colors of the first sub-pixel 100, the second sub-pixel 200 and the third sub-pixel 300 can be mixed into white light. For example, the first sub-pixel 100 is a red sub-pixel (R), the second sub-pixel 200 is a green sub-pixel (G), and the third sub-pixel 300 is a blue sub-pixel (B); or, the first sub-pixel 100 is a green sub-pixel (G), the second sub-pixel 200 is a red sub-pixel (R), and the third sub-pixel 300 is a blue sub-pixel (B).

[0048] The specific shapes of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 are not limited, and may be, for example, rectangular, triangular, pentagonal, or other shapes. Furthermore, the aperture areas of the red sub-pixel and the green sub-pixel are both smaller than the aperture area of ​​the blue sub-pixel.

[0049] In the following embodiments, the pixel arrangement structure provided by the present disclosure is illustrated by taking the shape of each sub-pixel as a rectangle, the first sub-pixel 100 as a red sub-pixel (R), the second sub-pixel 200 as a green sub-pixel (G), and the third sub-pixel 300 as a blue sub-pixel (B).

[0050] Furthermore, in this exemplary embodiment, Figure 3 As shown, the pixel arrangement structure includes a plurality of pixel columns arranged along a row direction, and in each pixel column, the first pixel repeating unit S1 and the second pixel repeating unit S2 are alternately arranged; or as shown Figure 1 and Figure 2 As shown, the pixel arrangement structure includes a first pixel column and a second pixel column alternately arranged along the row direction, the first pixel column includes a plurality of first pixel repeating units S1 arranged in sequence along the column direction, and the second pixel column includes a plurality of second pixel repeating units S2 arranged in sequence along the column direction.

[0051] That is, in the column direction, the sub-pixels in each pixel unit on the same pixel column are arranged in the same manner, that is, they are all first pixel repeating units S1 or they are all second pixel repeating units S2; alternatively, in the column direction, the first pixel repeating units S1 and the second pixel repeating units S2 may be arranged alternately on the same pixel column.

[0052] In the pixel arrangement structure of the embodiment of the present disclosure, since the pixel pattern of the second pixel repeating unit S2 is the same as the pattern obtained by rotating the first pixel repeating unit S1 90° clockwise or counterclockwise, taking the third sub-pixel 300 as a blue sub-pixel and the third sub-pixel 300 as an example, in the pixel row direction, the third sub-pixel 300 is arranged both horizontally and vertically. In this way, the first sub-pixel 100 and the second sub-pixel 200 in the first pixel repeating unit S1 can also borrow the third sub-pixel 300 in the second pixel repeating unit S2. Therefore, the pixel arrangement structure provided by the embodiment of the present disclosure combines the advantages of both the Real RBG arrangement and the Pentile arrangement, thereby effectively improving the display effect.

[0053] Figure 4 Shown are structural schematic diagrams of other embodiments of the present disclosure.

[0054] like Figure 4As shown, in some other embodiments of the present disclosure, in the same pixel row, the first pixel repeating unit S1 and the first sub-pixel 100 in the second pixel repeating unit S2 adjacent to the first pixel repeating unit S1 are adjacent, and the first sub-pixel 100 in the first pixel repeating unit S1 and the first sub-pixel 100 in the second pixel repeating unit S2 have the same width in the column direction, so that the light-emitting material layer of the first sub-pixel 100 in the first pixel repeating unit S1 and the first sub-pixel 100 in the second pixel repeating unit S2 can be formed by evaporation through the same pixel opening on the mask.

[0055] above Figure 4 The embodiment shown, with Figure 1 Compared with the embodiment shown in the figure, the difference is that the first sub-pixel 100 in the first pixel repeating unit S1 and the first sub-pixel 100 in the second pixel repeating unit S2 have the same width in the column direction, both of which are x. For example, the arrangement direction of the second sub-pixel 200 and the third sub-pixel 300 in the first pixel repeating unit S1 is perpendicular to the arrangement direction of the second sub-pixel 200 and the third sub-pixel 300 in the second pixel repeating unit S2, and the arrangement direction of the first sub-pixel 100 in the first pixel repeating unit S1 is the same as the arrangement direction of the first sub-pixel 100 in the second pixel repeating unit S2.

[0056] because Figure 4 In the embodiment shown, when the distance between two adjacent first sub-pixels 100 in the first pixel repeating unit S1 and the second pixel repeating unit S2 is small, it affects the difficulty and yield of manufacturing the evaporation mask. Figure 4 In the embodiment shown, two adjacent first sub-pixels 100 can be designed to have the same width in the column direction, that is, the edges of the two adjacent first sub-pixels 100 in the row direction are flush. In this way, the two adjacent first sub-pixels 100 can be designed as a 2 in 1 arrangement, that is, the two adjacent first sub-pixels 100 are integrated into the same opening on the evaporation mask.

[0057] Since a pixel definition layer (PDL) is provided on a display substrate, such as an OLED display substrate, and a groove (gap) is opened on the pixel definition layer to define each sub-pixel, the two adjacent first sub-pixels 100 are integrated into the same opening on the evaporation mask. When the light-emitting material layer on the first sub-pixel 100 is evaporated, the light-emitting material layer in the two sub-pixels will still be formed in different sub-pixel grooves, which will not affect the display function of the first sub-pixel 100. Therefore, the above scheme can improve the aperture ratio of the first sub-pixel 100 under the same PDL gap, thereby bringing better picture quality display effect and display performance, while reducing the difficulty of mask production of the first sub-pixel 100, improving the yield, and improving the aperture ratio of the first sub-pixel 100.

[0058] In some embodiments, as Figure 4 As shown, in the first pixel repeating unit and the second pixel repeating unit arranged adjacent to each other in the row direction, the row-wise spacing between two first sub-pixels 100 of the same color is smaller than the spacing between any two adjacent sub-pixels of different colors. In other words, the spacing between adjacent first sub-pixels 100 is designed to be smaller than the spacing between conventional sub-pixels. This facilitates the implementation of a 2-in-1 design for the first sub-pixels 100, i.e., facilitates integrating two adjacent first sub-pixels 100 into the same opening on the evaporation mask.

[0059] In this exemplary embodiment, the sizes of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 may be defined as follows:

[0060] The width of the first sub-pixel 100 in the first pixel repeating unit S1 in the column direction is the same as the width of the second sub-pixel 200 in the second pixel repeating unit S2 in the column direction, both are x; the width of the second sub-pixel 200 in the first pixel repeating unit S1 in the column direction is the same as the width of the third sub-pixel 300 in the second pixel repeating unit S2 in the column direction, both are y.

[0061] by Figure 4As shown in the example, assuming each sub-pixel is rectangular, the sub-pixel length and width refer to the width of the sub-pixel in the row direction and the length in the column direction within the first pixel repeating unit S1. Therefore, within each pixel repeating unit, the width of the first sub-pixel 100 is the same as the width of the second sub-pixel 200; the length of the second sub-pixel 200 is the same as the width of the third sub-pixel 300; and there are no restrictions on the length of the first sub-pixel 100 or the width of the second sub-pixel 200. Furthermore, the second sub-pixel 200 within the first pixel repeating unit S1 and the second sub-pixel 200 within the second pixel repeating unit S2, as well as the third sub-pixel 300 within the first pixel repeating unit S1 and the third sub-pixel 300 within the second pixel repeating unit S2, are relatively far apart and can be designed in a 1-in-1 configuration (i.e., each sub-pixel has a separate mask opening).

[0062] In addition, in this exemplary embodiment, the pixel arrangement structure includes a first pixel column and a second pixel column alternately arranged along the row direction, the first pixel column includes a plurality of first pixel repeating units S1 arranged in sequence along the column direction, and the second pixel column includes a plurality of second pixel repeating units S2 arranged in sequence along the column direction.

[0063] That is, in the row direction, the first pixel repeating unit S1 and the second pixel repeating unit S2 are alternately arranged in the same row; in the column direction, the sub-pixels in each pixel unit on the same pixel column are arranged in the same manner.

[0064] In some other embodiments, the pixel arrangement structure may include a plurality of pixel columns arranged along a row direction, and in each pixel column, the first pixel repeating unit S1 and the second pixel repeating unit S2 are alternately arranged.

[0065] Figure 5 Shown are schematic diagrams of pixel arrangement structures according to other embodiments of the present disclosure.

[0066] like Figure 5 As shown, in other exemplary embodiments, the pixel arrangement structure includes a first pixel column and a second pixel column alternately arranged along the row direction, the first pixel column includes a plurality of first pixel repeating units S1 arranged in sequence along the column direction, and the second pixel column includes a plurality of second pixel repeating units S2 arranged in sequence along the column direction; wherein, in the first pixel column, at least two adjacent rows of first pixel repeating units S1 form a group, and the third sub-pixels 300 in the same group of pixel repeating units are adjacent and have the same width in the row direction, so that the light-emitting material layer of the third sub-pixels 300 in the same group of pixel repeating units can be formed by evaporation through the same pixel opening on the mask.

[0067] above Figure 5The embodiment shown, with Figure 1 Compared with the embodiment shown, the only difference is that

[0068] The pixel repeating units in the same pixel column are identical, and in the first pixel column where the first pixel repeating unit S1 is located, the spacing between two adjacent third sub-pixels 300 can be made very small, and their widths in the row direction can be the same, so that the light-emitting material layer of the third sub-pixels 300 in the same group of pixel repeating units can be formed by vapor deposition through the same pixel opening on the mask. In this way, two adjacent third sub-pixels 300 can be designed in a 2-in-1 arrangement, that is, the two adjacent third sub-pixels 300 are integrated into the same opening on the vapor deposition mask.

[0069] The above solution can improve the aperture ratio of the third sub-pixel 300 under the same PDL gap, thereby bringing better picture quality display effect and display performance. At the same time, when the first pixel column where the first pixel unit is located is evaporated with light-emitting material, since the first pixel column and the second pixel column are arranged alternately, the evaporation mask template can be designed as an evaporation strip (slit strip), thereby improving the aperture ratio of the third sub-pixel 300, reducing the production difficulty of the evaporation strip of the third sub-pixel 300, and improving the yield.

[0070] In some embodiments, as Figure 5 As shown, the spacing between the third sub-pixels 300 in the same group of pixel repeating units in the column direction is smaller than the spacing between any two adjacent sub-pixels of different colors in the first pixel repeating unit and the second pixel repeating unit arranged adjacently in the row direction.

[0071] In other words, the spacing between adjacent third sub-pixels 300 is designed to be smaller than the spacing between conventional sub-pixels. This facilitates achieving a 2-in-1 design for the third sub-pixels 300, i.e., facilitating the integration of two adjacent third sub-pixels 300 into the same opening on the evaporation mask. Furthermore, in this exemplary embodiment, the sub-pixel arrangement structure of the first pixel repeating unit S1, rotated 90°, is identical to the pixel arrangement pattern of the second pixel repeating unit S2. The size, shape, and spacing of the sub-pixels in the first and second pixel repeating units S1 and S2 are identical; only the arrangement direction and position differ.

[0072] In addition, in this exemplary embodiment, the size, shape, and spacing of the first sub-pixel 100 , the second sub-pixel 200 , and the third sub-pixel 300 are not limited.

[0073] In addition, it should be noted that, in this embodiment, the third sub-pixels 300 are arranged in the same direction in the same pixel column, but are not arranged in the same direction in all pixel column directions. That is to say, taking the figure as an example, on adjacent pixel columns, the third sub-pixels 300 are arranged vertically in one column and horizontally in one column, and the vertically arranged third sub-pixels 300 and the horizontally arranged third sub-pixels 300 are spaced apart in the row direction.

[0074] Figure 6 Shown are schematic diagrams of pixel arrangement structures in some other exemplary embodiments of the present disclosure.

[0075] like Figure 6 As shown, in this exemplary embodiment, two adjacent first sub-pixels 100 in the same pixel row and two adjacent third sub-pixels 300 in the same pixel column are designed to be arranged in a 2-in-1 manner. Based on the above scheme, it is possible to simultaneously improve the aperture ratio of the first sub-pixel 100 and the third sub-pixel 300 under the same PDL gap, thereby improving the display effect and performance of the display panel; and at the same time, reduce the production difficulty of the evaporation mask templates of the first sub-pixel 100 and the third sub-pixel 300, thereby improving the yield.

[0076] Furthermore, in the pixel arrangement structure provided by the present disclosure, as shown in the figure, the first virtual triangle A and the second virtual triangle B are both isosceles triangles. The line connecting the centers of the first sub-pixel 100 and the third sub-pixel 300 is one side of the isosceles triangle, and the line connecting the centers of the second sub-pixel 200 and the third sub-pixel 300 is the other side of the isosceles triangle. In other words, the third sub-pixel 300 is located midway between the line connecting the centers of the first sub-pixel 100 and the second sub-pixel 200.

[0077] Of course, it is understandable that, in actual applications, the shapes, sizes, spacings, and specific locations of the first sub-pixel 100 , the second sub-pixel 200 , and the third sub-pixel 300 are not limited thereto.

[0078] It should be understood that, based on the same inventive concept as the embodiment of the present disclosure, any variation on the basis of the embodiment of the present disclosure should also fall within the protection scope of the embodiment of the present disclosure, for example, a pixel arrangement structure including four sub-pixels in each pixel repetition unit.

[0079] In addition, an embodiment of the present disclosure further provides a display device, including the pixel arrangement structure provided by an embodiment of the present disclosure.

[0080] There are a few points to note:

[0081] (1) The drawings of the embodiments of the present disclosure only relate to the structures related to the embodiments of the present disclosure. Other structures may refer to conventional designs.

[0082] (2) For the sake of clarity, the thickness of layers or regions in the drawings used to describe the embodiments of the present disclosure are exaggerated or reduced, i.e., these drawings are not drawn to scale. It is understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "under" another element, the element may be "directly" "on" or "under" the other element or intervening elements may be present.

[0083] (3) In the absence of conflict, the embodiments of the present disclosure and the features therein may be combined with each other to form new embodiments.

[0084] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure should be based on the protection scope of the claims.
