[0063] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0064] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0065] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0066] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0067] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.
[0068] With the continuous development of display technology, the demand for display resolution continues to increase, and the design of high resolution increases the difficulty and cost of mask plates and processes. At the same time, the market demand for narrow bezels and full screens is gradually increasing, which also increases the difficulty and cost of mask plate processes. In addition, in the current pixel arrangement, there is a problem of strong jaggedness in oblique displays.
[0069] In order to solve the above problems, the present application provides a pixel arrangement, which arranges sub-pixels of the same color in rows along a first direction, and alternately arranges pixel rows of different colors along a second direction that intersects the first direction and has an acute angle, so that the oblique display jaggedness of the display panel is reduced, which is more conducive to the display of oblique stripes and more consistent with the chamfer and groove design of full-screen display products. On this basis, some sub-pixels in the same pixel row are further provided with shared pixel openings, which increases the pixel density, thereby further improving the display effect and reducing the process difficulty and cost of the mask plate.
[0070] See also Figure 1-Figure 4 , a pixel arrangement provided by an embodiment of the present application includes a plurality of pixel rows 10, and the pixel row 10 includes a plurality of sub-pixels 12 arranged along a first direction X. For example, in the same pixel row 10, all sub-pixels 12 are arranged along the first direction X. For another example, in the same pixel row 10, some sub-pixels 12 are arranged along the first direction X, and another part of the sub-pixels 12 are arranged along other directions.
[0071] The luminous colors of the multiple sub-pixels 12 in the same pixel row 10 are the same, and the multiple pixel rows 10 with different luminous colors are alternately arranged along the second direction Y, and the angle between the first direction X and the second direction Y is an acute angle. Specifically, the angle between the first direction X and the second direction Y can be 30°, 45°, or 60°, etc. When the second direction Y is a horizontal direction, the first direction X is inclined relative to the horizontal direction. Since a plurality of sub-pixels 12 of the same color are continuously arranged along the first direction X in a pixel row 10, the jagged feeling of the oblique stripes along the first direction X is reduced.
[0072] Among the plurality of pixel rows 10 arranged along the second direction Y, at least part of the pixel rows 10 include a plurality of pixel groups 11 arranged along the first direction X (see Figure 5 and Figure 6 ), the pixel group 11 includes at least two sub-pixels 12. The sub-pixels 12 can be set independently of each other, or they can share a pixel opening, that is, they are regarded as one pixel. In this way, the overall pixel opening ratio is improved, the pixel density is increased, and the display effect is further improved, and the process difficulty and cost of the mask are reduced.
[0073] In some embodiments, the pixel group 11 includes at least two sub-pixels 12 arranged along the first direction X. Thus, two adjacent sub-pixels 10 in the pixel group 11 along the first direction X are arranged more closely, thereby improving the overall pixel aperture ratio.
[0074] Combination Figure 1 and Figure 5 Optionally, the pixel group 11 includes three sub-pixels 12, and the centers of the three sub-pixels 12 coincide with the three vertices of the first virtual triangle T1, that is, the pixel group 11 includes three sub-pixels 12 arranged in a triangle, so that the arrangement of the three sub-pixels 12 in the pixel group 11 is more compact, further improving the pixel aperture ratio.
[0075] Optionally, one side of the first virtual triangle T1 is parallel to the first direction X, that is, the arrangement direction of two adjacent sub-pixels 12 in the pixel group 11 is parallel to the first direction X, that is, the arrangement direction of two adjacent sub-pixels 12 in the pixel group 11 is parallel to the arrangement direction of multiple pixel groups 11 in the pixel row 10. In this way, the aliasing effect of the oblique stripes along the first direction X is further reduced.
[0076] Optionally, one side of the first virtual triangle T1 is parallel to the second direction Y, that is, the arrangement direction of two adjacent sub-pixels 12 in the pixel group 11 is parallel to the arrangement direction of the multiple pixel rows 10. In other words, along the arrangement direction of the multiple pixel rows 10, there are multiple sub-pixels 12 with different luminous colors, wherein the number of sub-pixels 12 of some colors may be greater than the number of sub-pixels 12 of other colors. In this way, when performing white light synthesis, more sub-pixels 12 with lower luminous efficiency may be set, so that the desired white light synthesis effect can be obtained without differentially adjusting the luminous brightness of sub-pixels 12 with different luminous efficiencies, thereby simplifying the luminous control process.
[0077] Optionally, the first virtual triangle T1 is an equilateral triangle. In this way, the shapes of the multiple sub-pixels 12 in a pixel group 11 are regular, so that the multiple sub-pixels 12 in the pixel group 11 can be evenly distributed, which improves the uniformity of the display effect on the one hand and simplifies the pixel manufacturing process on the other hand.
[0078] Combination Figure 1 and Figure 5In some embodiments, the pixel group 11 includes three sub-pixels 12, and among the three sub-pixels 12 of a pixel group 11, any sub-pixel 12 is arranged adjacent to the other two sub-pixels 12, so that the three sub-pixels 12 in the pixel group 11 are arranged sufficiently closely, thereby making the pixel density higher.
[0079] Optionally, the pixel group 11 includes three hexagonal sub-pixels 12, and the shape of the pixel group 11 is centrally symmetrical. In this way, the multiple sub-pixels 12 are evenly and closely arranged.
[0080] Optionally, the angle between one side of the hexagonal sub-pixel 12 and the second direction Y is an acute angle. In this way, along the extension direction of the pixel row 10, the edge jaggedness of the plurality of sub-pixels 12 is weakened, thereby improving the problem of strong jaggedness in oblique display.
[0081] Optionally, the three sub-pixels 12 in the pixel group 11 are all in the shape of regular hexagons, thereby improving the uniformity of pixel arrangement.
[0082] See also Fig. 9 Optionally, the pixel group 11 includes three sub-pixels 12 in a triangular shape, and the shape of the pixel group 11 is centrally symmetrical. In this way, a uniform and compact pixel arrangement effect can also be obtained. Specifically, the sub-pixel 12 can be an isosceles triangle.
[0083] Combination Figure 1-Figure 4 In some embodiments, the plurality of pixel rows 10 include a plurality of first pixel rows 10a, a plurality of second pixel rows 10b, and a plurality of third pixel rows 10c, and the first pixel rows 10a, the second pixel rows 10b, and the third pixel rows 10c emit different colors of light and alternate in sequence along the second direction Y. Exemplarily, the light-emitting colors of the first pixel row 10a, the second pixel row 10b, and the third pixel row 10c are blue, green, and red, respectively.
[0084] The first pixel row 10a has a plurality of first recesses 10a1 arranged at intervals along the first direction X on one side facing the third pixel row 10c, and the third pixel row 10c has a plurality of second recesses 10c1 arranged at intervals along the first direction X on one side facing the first pixel row 10a, and the plurality of first recesses 10a1 correspond to the plurality of second recesses 10c1 one by one, and the first recesses 10a1 and the corresponding second recesses 10c1 are opposite to each other and are combined into a spacing area. The plurality of sub-pixels 12 of the second pixel row 10b located between the first pixel row 10a and the third pixel row 10c are located in the plurality of spacing areas one by one. In this way, the sub-pixels 12 of the first pixel row 10a, the second pixel row 10b, and the third pixel row 10c are closely arranged, thereby improving the pixel density.
[0085] Optionally, the shape of the sub-pixel 12 located in the corresponding spacing area is the same as the shape of the spacing area, so that the space in the spacing area can be more fully utilized and the pixel density can be improved.
[0086] Optionally, the shape of the spacer is a hexagon. Based on this, when the shapes of the sub-pixels 12 of the first pixel row 10a and the third pixel row 10c are also hexagonal, the shapes of all the sub-pixels 12 are hexagonal, so that all the sub-pixels 12 can be arranged in an orderly and dense manner, for example, in a honeycomb arrangement. In addition, this arrangement method helps to reduce the jagged feeling of the display of oblique lines, arcs and circles, thereby improving the display effect of the display product.
[0087] Continue reading Figure 1-Figure 4 , combined with Figure 7 and Figure 8 As shown, optionally, the first pixel row 10a includes a plurality of first pixel groups 11a arranged along the first direction X, and the first pixel group 11a includes a plurality of first sub-pixels 12a; the second pixel row 10b includes a plurality of second sub-pixels 12b arranged at intervals along the first direction X; the third pixel row 10c includes a plurality of second pixel groups 11b arranged along the first direction X, and the second pixel group 11b includes a plurality of third sub-pixels 12c. Each first pixel group 11a has a first concave portion 10a1, and each second pixel group 11b has a second concave portion 10c1. In this way, the first sub-pixel 12a, the second sub-pixel 12b, and the third sub-pixel 12c are each arranged along the first direction X, so that the oblique monochrome display has a good display effect. In addition, since the second sub-pixel 12b row 10 is arranged between the first sub-pixel 12a and the second sub-pixel 12b, the oblique composite color display also has a good display effect.
[0088] Optionally, the shape of the first pixel group 11a is the same as the shape of the second pixel group 11b. Thus, the shape of the pixel opening corresponding to the first pixel group 11a is the same as the shape of the pixel opening corresponding to the second pixel group 11b, making the mask structure simpler and the pixel manufacturing process simpler.
[0089] Combination Figure 1 and Fig.10 In some embodiments, the pixel arrangement includes a plurality of repeating units, such as a plurality of first repeating units 21, wherein the first repeating unit 21 includes a first pixel group 11a, two second sub-pixels 12b, and a second pixel group 11b arranged along the second direction Y. The two second sub-pixels 12b are separated by a first pixel group 11a.
[0090] Combination Figure 1 and Fig.11In some other embodiments, the pixel arrangement includes a plurality of repeating units, such as a plurality of second repeating units 22, and the second repeating unit 22 includes a first pixel group 11a, two second sub-pixels 12b, and a second pixel group 11b arranged along the second direction Y. The two second sub-pixels 12b are separated by a second pixel group 11b.
[0091] Based on this, when the first pixel group 11a includes three first sub-pixels 12a arranged in a triangle, and the second pixel group 11b includes three third sub-pixels 12c arranged in a triangle, the number of first sub-pixels 12a and third sub-pixels 12c in each repeating unit is greater than the number of second sub-pixels 12b. In this way, a sub-pixel 12 with a higher luminous efficiency can be selected as the second sub-pixel 12b, so that when performing white light synthesis, the desired white light synthesis effect can be obtained without differentially adjusting the luminous brightness of sub-pixels 12 with different luminous efficiencies, thereby simplifying the luminous control process.
[0092] Optionally, a plurality of repeating units are arranged in a row along the second direction Y, and a plurality of rows are arranged along the third direction, wherein the third direction is perpendicular to the second direction Y. In this way, a plurality of repeating units are evenly arranged in the horizontal and vertical directions of the display panel, so that the display uniformity of the display panel is better.
[0093] Optionally, two adjacent rows of repeating units are arranged in a staggered manner, so that the arrangement of the two adjacent rows of repeating units is more compact, thereby improving the pixel density.
[0094] Optionally, multiple repeating units are arranged in rows along the second direction Y, and multiple repeating units are arranged in columns along the first direction X. Thus, the angle between the row direction and the column direction of the repeating units is an acute angle, so that the oblique display of the composite color also has a good display effect.
[0095] See also Figure 1 In some embodiments, the pixel arrangement includes a plurality of pixel units 30, the pixel unit 30 includes a first sub-pixel 12a, a second sub-pixel 12b, and a third sub-pixel 12c, and at least one of the first sub-pixel 12a, the second sub-pixel 12b, and the third sub-pixel 12c is shared by two adjacent pixel units 30. The plurality of pixel units 30 are arranged in rows along the second direction Y, and a plurality of rows are arranged along the third direction; the third direction is perpendicular to the second direction Y. In this way, by pixel borrowing, relatively fewer sub-pixels 12 are used to simulate more pixel units 30, achieve higher resolution, and reduce the process difficulty and cost of the mask.
[0096] Optionally, two adjacent rows of pixel units 30 are arranged in a staggered manner, thereby increasing the arrangement density of the plurality of pixel units 30 .
[0097] Optionally, a plurality of pixel units 30 are arranged in rows along the second direction Y, and a plurality of pixel units 30 are arranged in columns along the first direction X. The angle between the row direction and the column direction of the pixel units 30 is an acute angle, so that the oblique display has a good display effect.
[0098] Combination Figure 1 and Fig.12 , further, the plurality of pixel units 30 include a plurality of first pixel units 31, and the first pixel unit 31 includes a first pixel group 11a, a second sub-pixel 12b, and a second pixel group 11b arranged in sequence along the second direction Y. When the first pixel group 11a and the second pixel group 11b have the same shape and both include three sub-pixels 12 arranged in a triangle, a first pixel unit 31 includes three first sub-pixels 12a, a second sub-pixel 12b, and three third sub-pixels 12c. Based on this, a sub-pixel 12 with higher luminous efficiency can be selected as the second sub-pixel 12b, so that when performing white light synthesis, the desired white light synthesis effect can be obtained without differentially adjusting the luminous brightness of sub-pixels 12 with different luminous efficiencies, thereby simplifying the luminous control process.
[0099] Optionally, in a first pixel unit 31, the center of the first pixel group 11a, the center of the second sub-pixel 12b, and the center of the second pixel group 11b respectively coincide with the three vertices of the second virtual triangle T2. In this way, the arrangement of the three sub-pixels 12 in the first pixel unit 31 is more compact, which is conducive to improving the pixel density.
[0100] Optionally, the second virtual triangle T2 is an isosceles triangle, so that the shape of the first pixel unit 31 is more regular, which is more conducive to the close arrangement of the plurality of first pixel units 31 .
[0101] Optionally, two first pixel units 31 adjacent to each other along the second direction Y share a second pixel group 11b, wherein one first pixel unit 31 is mirrored and can overlap with another first pixel unit 31 after translation along the second direction Y. In this way, a higher resolution is obtained with fewer sub-pixels 12 through pixel borrowing.
[0102] Optionally, two adjacent first pixel units 31 along the third direction are staggered, so as to further improve the arrangement density of the plurality of first pixel units 31 .
[0103] Optionally, the first sub-pixel 12a is a blue sub-pixel 12, the second sub-pixel 12b is a green sub-pixel 12, and the third sub-pixel 12c is a red sub-pixel 12. In this way, one first pixel unit 31 includes three blue sub-pixels 12, one green sub-pixel 12, and three red sub-pixels 12. Based on this, in the first pixel unit 31, the number of green sub-pixels 12 with higher luminous efficiency is relatively small, which reduces the total number of sub-pixels 12 in the first pixel unit 31 while ensuring a good white light synthesis effect.
[0104] See also Figure 1 Further, the plurality of pixel units 30 include a plurality of second pixel units 32 and a plurality of third pixel units 33. The second pixel unit 32 and the third pixel unit 33 have different structures. The second pixel unit 32 and the third pixel unit 33 both include a plurality of first sub-pixels 12a, a second sub-pixel 12b, and a plurality of third sub-pixels 12c. In the second pixel unit 32 and the third pixel unit 33, the plurality of first sub-pixels 12a and the plurality of third sub-pixels 12c surround the second sub-pixel 12b, the plurality of first pixels are arranged adjacently, and the plurality of third sub-pixels 12c are arranged adjacently. For example, the second pixel unit 32 includes two first sub-pixels 12a, one second sub-pixel 12b, and four third sub-pixels 12c, and the two first sub-pixels 12a and the four third sub-pixels 12c surround the second sub-pixel 12b. The third pixel unit 33 includes four first sub-pixels 12 a , one second sub-pixel 12 b , and two third sub-pixels 12 c . The four first sub-pixels 12 a and the two third sub-pixels 12 c surround the second sub-pixel 12 b .
[0105] Based on this, a sub-pixel 12 with higher luminous efficiency can be selected as the second sub-pixel 12b, so that when white light synthesis is performed, the desired white light synthesis effect can be obtained without differentially adjusting the luminous brightness of sub-pixels 12 with different luminous efficiencies, thereby simplifying the luminous control process.
[0106] Optionally, in a second pixel unit 32, the centers of the two first sub-pixels 12a and the four third sub-pixels 12c respectively coincide with the six vertices of the first virtual hexagon H1. In a third pixel unit 33, the centers of the four first sub-pixels 12a and the two third sub-pixels 12c respectively coincide with the six vertices of the second virtual hexagon H2. For example, the first virtual hexagon H1 and the second virtual hexagon H2 are both regular hexagons. In this way, the multiple sub-pixels 12 in the second pixel unit 32 and the third pixel unit 33 are closely arranged, which helps to improve the pixel density.
[0107] Optionally, in a second pixel unit 32, the center of the second sub-pixel 12b coincides with the center of the first virtual hexagon H1. In a third pixel unit 33, the center of the second sub-pixel 12b coincides with the center of the second virtual hexagon H2.
[0108] Based on this, since there are various combinations of pixel units 30, the display effect is helpful to reduce the jagged feeling of display of oblique lines, arcs and circles, thereby improving the product display effect.
[0109] Optionally, the plurality of second pixel units 32 and the plurality of third pixel units 33 are alternately arranged along the second direction Y, the plurality of second pixel units 32 are arranged along the first direction X, and the plurality of third pixel units 33 are arranged along the first direction X. In this way, the angle between the row direction and the column direction of the second pixel units 32, and the angle between the row direction and the column direction of the third pixel units 33 are both acute angles, so that the edge jaggedness is weakened along the extension direction of the second pixel units 32 and the third pixel units 33, thereby improving the problem of strong jaggedness in oblique display.
[0110] Optionally, the second pixel unit 32 and the third pixel unit 33 adjacent to each other along the second direction Y share a third sub-pixel 12c, or the second pixel unit 32 and the third pixel unit 33 adjacent to each other along the second direction Y share a first sub-pixel 12a. Two second pixel units 32 adjacent to each other along the first direction X share a third sub-pixel 12c, and two third pixel units 33 adjacent to each other along the first direction X share a first sub-pixel 12a. In this way, by pixel borrowing, more pixel units 30 are obtained by simulation with relatively fewer sub-pixels 12, achieving a higher resolution, and reducing the process difficulty and cost of the mask.
[0111] Continue reading Figure 1 In some embodiments, the centers of the plurality of first sub-pixels 12a, the plurality of second sub-pixels 12b, and the plurality of third sub-pixels 12c coincide with the first virtual straight line L1, and the first virtual straight line L1 is parallel to the second direction Y. For example, when the second direction Y is a horizontal direction, the line connecting the centers of the plurality of first sub-pixels 12a, the plurality of second sub-pixels 12b, and the plurality of third sub-pixels 12c is parallel to the horizontal direction, that is, the sub-pixels 12 of three colors in the horizontal direction can achieve a good white light composite effect in the horizontal direction, and when displaying a horizontal line, no obvious color fringing will appear on both sides of the horizontal line, which can reduce the abnormal display of horizontal edge color fringing.
[0112] Optionally, the centers of the plurality of first sub-pixels 12a, the plurality of second sub-pixels 12b, and the plurality of third sub-pixels 12c coincide with the second virtual straight line L2, and the second virtual straight line L2 is parallel to the third direction. For example, when the third direction is the vertical direction, the line connecting the centers of the plurality of first sub-pixels 12a, the plurality of second sub-pixels 12b, and the plurality of third sub-pixels 12c is parallel to the vertical direction, that is, the vertical direction includes sub-pixels 12 of three colors, and a good vertical white light composite effect can be achieved. When displaying a vertical line, no obvious color fringing will appear on both sides of the vertical line, which can reduce the abnormal display of vertical edge color fringing.
[0113] Optionally, the angle between the first direction X and the second direction Y is 45°, which is beneficial to the display of oblique stripes and is more consistent with the chamfer design and slot design of current products.
[0114] In some embodiments, the pixel arrangement further includes a control circuit, and the control circuit controls the adjacent sub-pixels 12 of the same color in the same pixel row 10 to light up synchronously, or the control circuit controls the adjacent sub-pixels 12 of the same color to light up independently. For example, the control circuits corresponding to the multiple sub-pixels 12 in the same pixel group 11 can be designed separately, and the multiple sub-pixels 12 of the same color in the same pixel group 11 can be controlled to light up simultaneously before stretching, and a single sub-pixel 12 can be controlled to light up separately after stretching. In this way, the display effect of the display panel after being stretched is less different from the display effect before being stretched, thereby improving the display effect after stretching.
[0115] Exemplarily, the display panel can be an OLED display panel, and the sub-pixel 12 includes at least an anode and a cathode, and a light-emitting unit located between the anode and the cathode. The control circuit applies a voltage between the anode and the cathode to stimulate carrier migration, which acts on the organic light-emitting layer in the light-emitting unit to emit light of the corresponding color.
[0116] Combination Figure 1 and Fig.13 Based on the same invention purpose, the present application also provides a display panel 1, which includes the pixel arrangement of the above embodiment.
[0117] Exemplarily, the display panel includes a display area 1a and a non-display area 1b, and the display area 1a displays images through a plurality of sub-pixels 12 arranged in the display area 1a. Specifically, the display area 1a may be rectangular, and the non-display area 1b is arranged around the display area 1a; of course, the shape and arrangement of the display area 1a and the non-display area 1b include but are not limited to the above examples. For example, when the display panel is used for a wearable device worn on a user, the display area 1a may have a circular shape like a watch; when the display substrate is used for display on a vehicle, the display area 1a and the non-display area 1b may adopt, for example, a circular, polygonal or other shape. The display area 1a is provided with a plurality of sub-pixels 12 that emit light of different colors.
