Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display devices, in particular to a pixel arrangement structure, a display panel and a mask assembly. BACKGROUND

[0002] An organic light-emitting diode (OLED) is an active light-emitting device. Compared with a traditional liquid crystal display (LCD) display mode, the OLED display technology does not need a backlight, and has a self-luminous characteristic. The OLED uses a thin film of organic material and a glass substrate, and when a current passes through, the organic material emits light. Therefore, the OLED display panel can significantly save power, can be made lighter and thinner, can withstand a wider range of temperature changes, and has a larger visual angle. The OLED display panel is expected to become the next generation of flat panel display technology after the LCD, and is one of the most concerned technologies in the current flat panel display technology.

[0106] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details, which are not necessary for understanding the present application. The following description of the embodiments is merely provided to give a better understanding of the present application by showing examples of the present application.

[0107] It should be noted that the terms such as first and second, etc., are merely intended to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between such entities or operations. Also, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that processes, methods, articles or devices including a series of elements not only include those elements, but also include other elements not explicitly listed or inherent to such processes, methods, articles or devices. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the processes, methods, articles or devices including the elements.

[0108] With the progress of science and technology, people have higher and higher requirements for display panels. Not only is a higher resolution required for display panels, but a higher display effect is also required. The pixel arrangement itself has a decisive effect on the display quality of the display panel. The common pixel arrangement in the display panel is a matrix type regular arrangement, which usually has a low transmittance, which is not conducive to the layout of the wiring. At the same time, this arrangement will form regular straight-line slits between the metal electrodes corresponding to the pixel structure, which will cause serious diffraction when external light passes through. The diffraction phenomenon increases the display haze and reduces the display effect.

[0109] To solve the above problems, please refer to Figures 1 to 5 The embodiment of the present application provides a pixel arrangement structure, which comprises a pixel unit 100, the pixel unit 100 comprises a first pixel group 110, a second pixel group 120 and a third pixel group 130 arranged around a virtual center point O. The first pixel group 110 comprises a plurality of first sub-pixels 111 arranged around a first virtual point O1, the second pixel group 120 comprises a plurality of second sub-pixels 121 arranged around a second virtual point O2, and the third pixel group 130 comprises a plurality of third sub-pixels 131 arranged around a third virtual point O3.

[0110] The plurality of first sub-pixels 111 emit light of the same color as a pixel group, so that the single-point color performance is better, and the display effect is better. At the same time, this design can be compatible with the COE (Color Filter on Encapsulation) technology, and further reduce the diffraction effect.

[0111] In the pixel unit 100, the projection of the first sub-pixel 111 closest to the virtual center point O in the first direction X is located between the projections of the two second sub-pixels 121 in the first direction X. The orthographic projection of the second sub-pixel 121 closest to the virtual center point O in the second direction Y is located between the projections of the two third sub-pixels 131 in the second direction Y, and the first direction X intersects the second direction Y.

[0112] It should be noted that the relative position of the third sub-pixel 131 closest to the virtual center point O is not limited in the embodiment of the present application. Exemplarily, as shown in Figure 2 , the projection of the third sub-pixel 131 closest to the virtual center point O in the third direction Z is located between the projections of the two first sub-pixels 111 in the third direction Z; or as shown in Figure 3 , the projection of the third sub-pixel 131 closest to the virtual center point O in the second direction X at least partially overlaps the projection of the first sub-pixel 111 closest to the virtual center point O.

[0113] The pixel arrangement structure includes first sub-pixels 111, second sub-pixels 121, and third sub-pixels 131 of three different colors. Optionally, the first sub-pixels 111, the second sub-pixels 121, and the third sub-pixels 131 are red, green, and blue sub-pixels, respectively.

[0114] The first sub-pixels 111 are arranged around a first virtual point O1 and combined to form a first pixel group 110. The first virtual point O1 refers to the geometric center of the first pixel group 110, i.e., the center of the first pixel group 110 coincides with the first virtual point O1. The first sub-pixels 111 can be arranged around the first virtual point O1 with intervals between them or abut each other. In addition, the number of first sub-pixels 111 in the first pixel group 110 is not limited in the embodiments of the present application. For example, as shown in FIG. 1A or 1B, the first pixel group 110 can include three or four first sub-pixels 111. Figure 2 Figure 3

[0115] The second sub-pixels 121 are arranged around a second virtual point O2 and combined to form a second pixel group 120. The second virtual point O2 refers to the geometric center of the second pixel group 120, i.e., the center of the second pixel group 120 coincides with the second virtual point O2. The second sub-pixels 121 can be arranged around the second virtual point O2 with intervals between them or abut each other. In addition, the number of second sub-pixels 121 in the second pixel group 120 is not limited in the embodiments of the present application. For example, as shown in FIG. 1A or 1B, the second pixel group 120 can include three or four second sub-pixels 121. Figure 2 Figure 3

[0116] The third sub-pixels 131 are arranged around a third virtual point O3 and combined to form a third pixel group 130. The third virtual point O3 refers to the geometric center of the third pixel group 130, i.e., the center of the third pixel group 130 coincides with the third virtual point O3. The third sub-pixels 131 can be arranged around the third virtual point O3 with intervals between them or abut each other. In addition, the number of third sub-pixels 131 in the third pixel group 130 is not limited in the embodiments of the present application. For example, as shown in FIG. 1A or 1B, the third pixel group 130 can include three or four third sub-pixels 131. Figure 2 Figure 3

[0117] ​​​​​​The first pixel group 110, the second pixel group 120, and the third pixel group 130 together form a pixel unit 100. The pixel unit 100 is the smallest repeating unit in the pixel arrangement structure. Multiple pixel units 100 are translated and repeated to form a pixel arrangement structure. For example, multiple pixel units 100 can be translated repeatedly along the row and column directions of the display panel to form a pixel arrangement structure.

[0118] In a single pixel unit 100, a first pixel group 110, a second pixel group 120, and a third pixel group 130 are arranged around a virtual center. The virtual center mentioned in this embodiment refers to the geometric center of the pixel unit 100, that is, the center of the pixel unit 100 coincides with the virtual center point O. The first pixel group 110, the second pixel group 120, and the third pixel group 130 can be arranged as follows: Figure 2 As shown, they are set at intervals around the virtual center point O; or they can be set as follows: Figure 4 As shown, they are set to oppose each other and surround the virtual center point O, but this embodiment of the application does not limit this.

[0119] In a single pixel unit 100, there exists a first sub-pixel 111 that is closest to the virtual center point O. In this embodiment, the location closest to the virtual center point O refers to the distance between the center point of the first sub-pixel 111 and the virtual center point O being less than the distance between the center point of any other first sub-pixel 111 in the first pixel group 110 and the virtual center point O.

[0120] The projection of the first sub-pixel 111 in the first direction X lies between the projections of the two second sub-pixels 121 in the first direction X. The first direction X mentioned here refers to the perpendicular direction of the line connecting the centers of the two second sub-pixels 121 in the second pixel group 120. Furthermore, one of these two second sub-pixels 121 can be the second sub-pixel 121 in the second pixel group 120 that is closest to the virtual center point O.

[0121] Furthermore, in a single pixel unit 100, there exists a second sub-pixel 121 that is closest to the virtual center point O. In this embodiment, the location closest to the virtual center point O refers to the distance between the center point of the second sub-pixel 121 and the virtual center point O being less than the distance between the center point of any other second sub-pixel 121 in the second pixel group 120 and the virtual center point O.

[0122] The projection of the second sub-pixel 121 in the second direction Y lies between the projections of the two third sub-pixels 131 in the second direction Y. The second direction Y mentioned here refers to the perpendicular direction of the line connecting the centers of the two third sub-pixels 131 in the third pixel group 130. Furthermore, one of these two third sub-pixels 131 can be the third sub-pixel 131 in the third pixel group 130 that is closest to the virtual center point O. The first direction X intersects the second direction Y; the included angle between the two is not limited in this embodiment. For example, as shown... Figure 3 As shown, the first direction X can be perpendicular to the second direction Y, or as... Figure 2 As shown, the first direction X and the second direction Y form a 60° angle.

[0123] It should be noted that, as Figure 2 As shown, a portion of the structure in the first sub-pixel 111, located closest to the virtual center point O, can be aligned with a portion of the structure in the two second sub-pixels 121. That is, the first sub-pixel 111, located closest to the virtual center point O, is embedded between the two second sub-pixels 121. Preferably, it is embedded in the middle of the two second sub-pixels 121, at equal distances from both. Alternatively, as... Figure 5 As shown, the first sub-pixel 111, which is closest to the virtual center point O, can also be located completely outside the line connecting any part of the structure of the two second sub-pixels 121. Preferably, the distance from the first sub-pixel 111, which is closest to the virtual center point O, to the center of the two second sub-pixels 121 is equal.

[0124] Similarly, a portion of the structure in the second sub-pixel 121 closest to the virtual center point O can be located on the same straight line as a portion of the structure in the two third sub-pixels 131. That is, the second sub-pixel 121 closest to the virtual center point O is embedded between the two third sub-pixels 131, preferably embedded in the middle of the two third sub-pixels 131, at equal distances from the two third sub-pixels 131. Alternatively, the second sub-pixel 121 closest to the virtual center point O can also be completely located outside the line connecting any portion of the structure in the two third sub-pixels 131. Preferably, the first sub-pixel 111 closest to the virtual center point O is equidistant from the two second sub-pixels 121.

[0125] Similarly, part of the structure in the third sub-pixel 131 at the position closest to the virtual center point O can be on the same line with part of the structure in the two first sub-pixels 111, that is, the third sub-pixel 131 at the position closest to the virtual center point O is embedded between the two first sub-pixels 111, preferably, embedded at the middle position of the two first sub-pixels 111, and the distances to the two first sub-pixels 111 are equal. Alternatively, the third sub-pixel 131 at the position closest to the virtual center point O can also be completely located outside the line connecting any part of the structure of the two first sub-pixels 111. Preferably, the distance from the center of the third sub-pixel 131 at the position closest to the virtual center point O to the center of the two first sub-pixels 111 is equal.

[0126] In summary, in the single pixel unit 100 in the embodiments of the present application, in the first direction X, the projection of the first sub-pixel 111 is sandwiched between the projections of the two second sub-pixels 121; and in the second direction Y, the projection of the second sub-pixel 121 is sandwiched between the projections of the two third sub-pixels 131. Compared with the matrix pixel arrangement, this design can avoid forming regular straight-line slits between the electrodes corresponding to the pixel arrangement structure, thereby reducing the degree of diffraction and improving the display effect of the corresponding display panel.

[0127] In some embodiments, as shown in Figs. 1-3, the projection of the third sub-pixel 131 in the third direction Z is located between the projections of the two first sub-pixels 111 in the third direction Z, and the first direction X, the second direction Y and the third direction Z intersect with each other and are located in the same plane. Figure 2 Figure 4 Figure 5 In some embodiments, as shown in Figs. 1-3, the projection of the third sub-pixel 131 in the third direction Z is located between the projections of the two first sub-pixels 111 in the third direction Z, and the first direction X, the second direction Y and the third direction Z intersect with each other and are located in the same plane.

[0128] In the single pixel unit 100, there is the third sub-pixel 131 at the position closest to the virtual center point O. In the embodiments of the present application, the position closest to the virtual center point O refers to the distance between the center point of the third sub-pixel 131 and the virtual center point O is less than the distance between the center point of any other third sub-pixel 131 in the third pixel group 130 and the virtual center point O.

[0129] Meanwhile, the projection of the third sub-pixel 131 in the third direction Z is located between the projections of the two first sub-pixels 111 in the first direction X. Here, the third direction Z refers to the direction of the perpendicular line of the line connecting the centers of the two first sub-pixels 111 in the first pixel group 110. And one of the two first sub-pixels 111 can be the first sub-pixel 111 at the position closest to the virtual center point O in the first pixel group 110.

[0130] ​​It should be noted that a portion of the structure in the third sub-pixel 131, which is closest to the virtual center point O, may be on the same straight line as a portion of the structure in the two first sub-pixels 111, or the third sub-pixel 131, which is closest to the virtual center point O, may be completely outside the line connecting any portion of the structure in the two first sub-pixels 111. This application embodiment does not impose any restrictions on this.

[0131] The first direction X, the second direction Y, and the third direction Z intersect each other and are all parallel to the light-emitting plane of the pixel arrangement structure. The embodiments of this application do not limit the angular relationships between the first direction X, the second direction Y, and the third direction Z. For example, the angle between any two of the first direction X, the second direction Y, and the third direction Z is 120°.

[0132] Since the projections of the sub-pixels of any one of the first pixel group 110, the second pixel group 120, and the third pixel group 130 are all sandwiched between the projections of two sub-pixels in another pixel group, the first pixel group 110, the second pixel group 120, and the third pixel group 130 form a head-to-tail wrapping trend around the virtual center line point. The first virtual point O1 corresponding to the first pixel group 110, the second virtual point O2 corresponding to the second pixel group 120, and the third virtual point O3 corresponding to the third pixel group 130 are connected to form a triangular structure, and the virtual center point O is located inside the triangular structure.

[0133] In this embodiment of the application, by adjusting the position of the third pixel group 130, the relative positions between the first pixel group 110, the second pixel group 120 and the third pixel group 130 are further improved, so that the three can form a head-to-tail wrapping trend, thereby further increasing the difficulty of forming a straight line region between adjacent pixel groups and reducing diffraction problems.

[0134] It should be noted that the relative positional relationships between different pixel units are not limited in the embodiments of this application. For example, as shown... Figure 1 As shown, the virtual center points O in the four pixel groups can collectively form a second virtual quadrilateral S6, and the intersection of the two angle bisectors of the second virtual quadrilateral S6 coincides with the virtual center point O in another pixel group. Furthermore, the second virtual triangle S6 can be a square or a rectangular structure other than a square.

[0135] In some embodiments, such as Figure 2 As shown, the projection of the first sub-pixel 111, which is closest to the virtual center point O, onto the first direction X is located exactly in the middle of the projections of the two second sub-pixels 121 onto the first direction X. That is, the distance between the first sub-pixel 111, which is closest to the virtual center point O, and the center line connecting the two corresponding second sub-pixels 121 is the same.

[0136] like Figure 8 as well as Figure 11 As shown, in this embodiment of the application, the position of the second pixel group 110 is determined through the first pixel group 120. Specifically, during the pixel arrangement process, a first virtual triangle S1 formed by three first sub-pixels 11 is first determined. A line is drawn connecting the vertices of the first virtual triangle S1 and a point, that is, the two first sub-pixels 111 that are farther away from the virtual center point O among the three first sub-pixels 111, for example... Figure 11 Draw a line L1 connecting R2 and R3, and then draw a perpendicular line L2 from R3 to L1. Next, for the vertex of the first virtual triangle S1, i.e., the first sub-pixel 111 which is farther from the virtual center point O (i.e., R2 in the diagram), draw the angle bisector of the angle in the first virtual triangle S1 corresponding to R2. The point where the perpendicular line L2 intersects the angle bisector is determined as the vertex of the third virtual triangle S3, i.e., the position of one of the third sub-pixels 131.

[0137] Similarly, the second sub-pixel 121 and the third sub-pixel 131 also conform to the above arrangement rules, which will not be repeated in the embodiments of this application.

[0138] In some embodiments, please refer to Figure 6 The first sub-pixel 111, located at the position closest to the virtual center point O, is at least partially embedded between the two second sub-pixels 121. In this embodiment, "embedded" means that in a single pixel unit 100, a portion of the structure of the first sub-pixel 111, located at the position closest to the virtual center point O, and portions of the structures of the two second sub-pixels 121 are located on the same straight line. Figure 6 Two auxiliary dashed lines are set in the middle. The part of the two auxiliary dashed lines is the part of the structure of the first sub-pixel 111, which is closest to the virtual center point O, embedded between the two second sub-pixels 121.

[0139] Since the first sub-pixel 111, located closest to the virtual center point O, is at least partially embedded between the two second sub-pixels 121, there is no gap between the first sub-pixel 111 and the corresponding two second sub-pixels 121 in the first direction X. This design prevents the formation of a regular rectangular gap between the first pixel group 110 and the second pixel group 120, thereby reducing the degree of diffraction and improving the display effect.

[0140] In some embodiments, the second sub-pixel 121, located closest to the virtual center point O, is at least partially embedded between two third sub-pixels 131. The term "embedded" in this embodiment refers to the fact that, within a single pixel unit 100, a portion of the structure of the second sub-pixel 121 closest to the virtual center point O and portions of the structures of the two third sub-pixels 131 are located on the same straight line.

[0141] Since the second sub-pixel 121 closest to the virtual center point O is at least partially embedded between two third sub-pixels 131, the second sub-pixel 121 and the corresponding two third sub-pixels 131 do not have a gap in the second direction Y. This design makes it impossible to form a regular rectangular gap space between the second pixel group 120 and the third pixel group 130, thereby reducing the degree of diffraction and improving the display effect.

[0142] In some embodiments, the third sub-pixel 131 closest to the virtual center point O is at least partially embedded between two first sub-pixels 111. The “embedded” mentioned in the embodiments of the present application means that in a single pixel unit 100, the partial structure of the third sub-pixel 131 closest to the virtual center point O and the partial structure of the two first sub-pixels 111 are located on the same straight line.

[0143] Since the third sub-pixel 131 closest to the virtual center point O is at least partially embedded between two first sub-pixels 111, the third sub-pixel 131 and the corresponding two first sub-pixels 111 do not have a gap in the third direction Z. This design makes it impossible to form a regular rectangular gap space between the first pixel group 110 and the third pixel group 130, thereby reducing the degree of diffraction and improving the display effect.

[0144] In some embodiments, please refer to Figure 7 , the first sub-pixel 111 closest to the virtual center point O, the second sub-pixel 121 closest to the virtual center point O, and one third sub-pixel 131 in the third pixel group 130 are located on a straight line.

[0145] The “located on a straight line” mentioned in the embodiments of the present application means that the center point of the first sub-pixel 111 closest to the virtual center point O, the center point of the second sub-pixel 121 closest to the virtual center point O, and the center point of one third sub-pixel 131 in the third pixel group 130 are located on the same straight line. Among them, the third sub-pixel 131 is the third sub-pixel 131 farthest from the virtual center point O in the third pixel group 130.

[0146] The second sub-pixel 121 closest to the virtual center point O is arranged between the first sub-pixel 111 closest to the virtual center point O and one third sub-pixel 131 in the third pixel group 130. Among the three, the distance of the center line between the second sub-pixel 121 and the first sub-pixel 111 can be the same as the distance of the center line between the second sub-pixel 121 and the third sub-pixel 131, or can be different. In addition, the extension direction of the straight line where the three are located can be parallel to the third direction Z, or there can be a certain inclination angle between the third direction Z, and the present application embodiment does not limit this.

[0147] In some other embodiments, as shown in FIG. 1C, the second sub-pixel 121 closest to the virtual center point O, the third sub-pixel 131 closest to the virtual center point O, and one first sub-pixel 111 in the first pixel group 110 are located on a straight line. Figure 7

[0148] The "located on a straight line" mentioned in the embodiments of the present application means that the center point of the second sub-pixel 121 closest to the virtual center point O, the center point of the third sub-pixel 131 closest to the virtual center point O, and the center point of one first sub-pixel 111 in the first pixel group 110 are located on the same straight line. Among them, the first sub-pixel 111 is the first sub-pixel 111 farthest from the virtual center point O in the first pixel group 110.

[0149] The third sub-pixel 131 closest to the virtual center point O is arranged between the second sub-pixel 121 closest to the virtual center point O and one first sub-pixel 111 in the first pixel group 110. Among the three, the distance of the center line between the third sub-pixel 131 and the first sub-pixel 111 can be the same as the distance of the center line between the third sub-pixel 131 and the second sub-pixel 121, or can be different. In addition, the extension direction of the straight line where the three are located can be parallel to the first direction X, or there can be a certain inclination angle between the first direction X, and the present application embodiment does not limit this.

[0150] In some other embodiments, as shown in FIG. 1C, the second sub-pixel 121 closest to the virtual center point O, the third sub-pixel 131 closest to the virtual center point O, and one first sub-pixel 111 in the first pixel group 110 are located on a straight line. Figure 7

[0151] ​​The "on a straight line" mentioned in the embodiments of the present application refers to that the straight line is located between any two of the following three points: the center point of the third sub-pixel 131 closest to the virtual center point O, the center point of the first sub-pixel 111 closest to the virtual center point O, and the center point of one second sub-pixel 121 in the second pixel group 120. The third sub-pixel 131 is the third sub-pixel 131 farthest from the virtual center point O in the third pixel group 130.

[0152] The second sub-pixel 121 closest to the virtual center point O is arranged between the first sub-pixel 111 closest to the virtual center point O and one third sub-pixel 131 in the third pixel group 130. Among the three, the distance between the center connection line between the first sub-pixel 111 and the second sub-pixel 121 can be the same as the distance between the center connection line between the first sub-pixel 111 and the third sub-pixel 131, or can be different. In addition, the extension direction of the straight line on which the three are located can be parallel to the second direction Y, or there can be a certain inclination angle between the second direction Y, and the embodiments of the present application do not limit this.

[0153] In the above several schemes, by adjusting the positions of part of the first sub-pixels 111, the second sub-pixels 121 and the third sub-pixels 131 in the pixel unit 100, the three can be located on the same straight line, so that the diffraction is reduced, and at the same time, the regular arrangement between part of the first sub-pixels 111, part of the second sub-pixels 121 and part of the third sub-pixels 131 can be realized, thereby improving the display uniformity.

[0154] In some embodiments, referring to Figure 8 , the first pixel group 110 includes three first sub-pixels 111, and the three first sub-pixels 111 form a first virtual triangle S1.

[0155] The first pixel group 110 includes three first sub-pixels 111, and the center connection line of the three first sub-pixels 111 forms a first virtual triangle S1, and the first virtual point O1 is located in the first virtual triangle S1. The specific size and shape of the first virtual triangle S1 are not limited in the embodiments of the present application, and the distances between the first virtual point O1 and the three end points of the first virtual triangle S1 can be the same or different.

[0156] The number of the first sub-pixels 111 in the first pixel group 110 is set to three in the embodiment of the application, and then the relative positions among the first sub-pixels 111 are determined by adjusting the positions of the end points of the first virtual triangle S1. Compared with the scheme of more first sub-pixels 111, the embodiment of the application can increase the distance between the adjacent first sub-pixels 111, thereby reducing the difficulty of evaporation of the first sub-pixels 111 in the process of manufacturing the display panel.

[0157] In some other embodiments, as shown in Figure 8 The second pixel group 120 includes three second sub-pixels 121, and the three second sub-pixels 121 form a second virtual triangle S2.

[0158] The second pixel group 120 includes three second sub-pixels 121, and the centers of the three second sub-pixels 121 form a second virtual triangle S2. A second virtual point O2 is located in the second virtual triangle S2. The specific size and shape of the second virtual triangle S2 are not limited in the embodiment of the application, and the distances between the second virtual point O2 and the three end points of the second virtual triangle S2 can be the same or different.

[0159] The number of the second sub-pixels 121 in the second pixel group 120 is set to three in the embodiment of the application, and then the relative positions among the second sub-pixels 121 are determined by adjusting the positions of the end points of the second virtual triangle S2. Compared with the scheme of more second sub-pixels 121, the embodiment of the application can increase the distance between the adjacent second sub-pixels 121, thereby reducing the difficulty of evaporation of the second sub-pixels 121 in the process of manufacturing the display panel.

[0160] In some other embodiments, as shown in Figure 8 The third pixel group 130 includes three third sub-pixels 131, and the three third sub-pixels 131 form a third virtual triangle S3.

[0161] The third pixel group 130 includes three third sub-pixels 131, and the centers of the three third sub-pixels 131 form a third virtual triangle S3. A third virtual point O3 is located in the second virtual triangle S2. The specific size and shape of the third virtual triangle S3 are not limited in the embodiment of the application, and the distances between the third virtual point O3 and the three end points of the third virtual triangle S3 can be the same or different.

[0162] In the embodiment of the present application, the number of the third sub-pixels 131 in the third pixel group 130 is set to three, and then the relative positions among the third sub-pixels 131 are determined by adjusting the positions of the end points of the third virtual triangle S3. Compared with the case of more third sub-pixels 131, the embodiment of the present application can increase the distance between the adjacent third sub-pixels 131, thereby reducing the difficulty of evaporation of the third sub-pixels 131 in the process of manufacturing the display panel.

[0163] In some embodiments, referring to Figure 9 and Figure 10 , the first virtual triangle S1 is an isosceles triangle. The first virtual triangle S1 can be a longitudinal isosceles triangle as shown in Figure 9 , or a transverse isosceles triangle as shown in Figure 10 .

[0164] In the embodiment of the present application, the first virtual triangle S1 is an isosceles triangle, which means that the length of the line connecting the center of at least one first sub-pixel 111 in the first pixel group 110 with the center of another first sub-pixel 111 is the same. This design enables the three first sub-pixels 111 in the first pixel group 110 to be arranged in a certain rule, thereby reducing diffraction and improving display effect. Alternatively, at least one of the second virtual triangle S2 and the third virtual triangle S3 is also an isosceles triangle.

[0165] In some embodiments, as shown in Figure 8 , the first virtual triangle S1 is an equilateral triangle.

[0166] In the embodiment of the present application, the first virtual triangle S1 is an equilateral triangle, which means that the length of the line connecting the center of any one first sub-pixel 111 in the first pixel group 110 with the center of another first sub-pixel 111 is the same. This design can further improve the uniformity of the arrangement of the first sub-pixels 111 in the first pixel group 110, thereby improving display effect. In the embodiment of the present application, the length of the side of the first virtual triangle S1 is not limited.

[0167] In some alternative embodiments, at least one of the second virtual triangle S2 and the third virtual triangle S3 is also an equilateral triangle.

[0168] In some embodiments, as shown in Figure 8 , the distance between at least two of the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 closest to the virtual center point O and the virtual center point O is equal.

[0169] In the first pixel group 110, the distances between different first sub-pixels 111 and the virtual center point O are different, and thus there is a first sub-pixel 111 at a position closest to the virtual center point O. In the second pixel group 120, the distances between different second sub-pixels 121 and the virtual center point O are different, and thus there is a second sub-pixel 121 at a position closest to the virtual center point O. In the third pixel group 130, the distances between different third sub-pixels 131 and the virtual center point O are different, and thus there is a third sub-pixel 131 at a position closest to the virtual center point O. Moreover, the three sub-pixels of different colors closest to the virtual center point O can jointly constitute a light-emitting unit, thereby meeting actual light-emitting needs.

[0170] On this basis, the distances between at least two of the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 131 at the positions closest to the virtual center point O and the virtual center point O are set to be equal, that is, among the three sub-pixels, there are at least two sub-pixels whose corresponding center-to-virtual center point O connecting lines have the same length. Exemplarily, the distance between the first sub-pixel 111 at the position closest to the virtual center point O and the virtual center point O is equal to the distance between the second sub-pixel 121 at the position closest to the virtual center point O and the virtual center point O.

[0171] This design makes the light-emitting center of the light-emitting unit constituted by the three sub-pixels of different colors closest to the virtual center point O as close as possible to the virtual center point O, that is, the light-emitting center is located at the central position of the entire pixel unit 100 as much as possible, thereby being capable of improving display uniformity.

[0172] In some embodiments, the distances between the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 131 at the positions closest to the virtual center point O and the virtual center point O are all equal.

[0173] In the embodiments of the present application, the distances between the first sub-pixel 111 at the position closest to the virtual center point O and the virtual center point O, the distance between the second sub-pixel 121 at the position closest to the virtual center point O and the virtual center point O, and the distance between the third sub-pixel 131 at the position closest to the virtual center point O and the virtual center point O are all the same. Therefore, the light-emitting center of the light-emitting unit constituted by the three sub-pixels of different colors closest to the virtual center point O corresponds to the virtual center point O, that is, the light-emitting center is located at the central position of the entire pixel unit 100, thereby realizing the unity of physical structure and display effect and further improving display uniformity.

[0174] In some embodiments, as Figure 8As shown, the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 closest to the virtual center point O are connected to form a fourth virtual triangle S4, and the fourth virtual triangle S4 is an equilateral triangle.

[0175] The centers of the three different color sub-pixels closest to the virtual center point O are connected to form a fourth virtual triangle S4, and the three endpoints of the fourth virtual triangle S4 are the center of the first sub-pixel 111, the center of the second sub-pixel 121 and the center of the third sub-pixel 131, and the virtual center point O is inside the fourth virtual triangle S4.

[0176] The fourth virtual triangle S4 is an equilateral triangle, that is, the distance between any two of the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 closest to the virtual center point O is equal. At the same time, the distance between the three sub-pixels and the virtual center point O is also the same. This design can reduce diffraction while further realizing regular arrangement of sub-pixels and ensuring reliable and stable display effect.

[0177] In some embodiments, the first virtual triangle S1 includes a first virtual edge L1 connecting two first sub-pixels 111 far from the virtual center point O, and the fourth virtual triangle S4 includes a second virtual edge L2 connecting the second sub-pixel 121 and the third sub-pixel 131 closest to the virtual center point O, and the first virtual edge L1 and the second virtual edge L2 perpendicularly intersect at a first sub-pixel 111 far from the virtual center point O.

[0178] From the foregoing, it can be seen that the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 are sub-pixels of different colors. On this basis, in order to facilitate the specific description of the pixel arrangement structure later, the following embodiments of the present application will be described with reference to the accompanying drawings. Figure 8 and Figure 11 and will be described taking the first sub-pixel 111 as a red sub-pixel, the second sub-pixel 121 as a green sub-pixel and the third sub-pixel 131 as a blue sub-pixel as an example. Among them, the plurality of first sub-pixels 111 includes a first red sub-pixel R1, a second red sub-pixel R2 and a third red sub-pixel R3; the plurality of second sub-pixels 121 includes a first green sub-pixel G1, a second green sub-pixel G2 and a third green sub-pixel G3; and the plurality of third sub-pixels 131 includes a first blue sub-pixel B1, a second blue sub-pixel B2 and a third blue sub-pixel B3, and the first red sub-pixel R1, the first green sub-pixel G1 and the first blue sub-pixel B1 are different color sub-pixels closest to the virtual center point O.

[0179] The two end points of the first virtual side L1 are the centers of the second red sub-pixel R2 and the third red sub-pixel R3 respectively, and the two end points of the second virtual side L2 are the centers of the first green sub-pixel G1 and the first blue sub-pixel B1 respectively. The extension line of the second virtual side L2 and the first virtual side L1 intersect at the third red sub-pixel R3, that is, the centers of the third red sub-pixel R3, the first blue sub-pixel B1 and the first green sub-pixel G1 are located on the same straight line.

[0180] On this basis, the first virtual side L1 and the second virtual side L2 are vertically arranged, so as to further limit the relationship between the different color sub-pixels in the pixel unit 100, so that they can be arranged more regularly, and the display uniformity is improved.

[0181] In some embodiments, referring to Figure 8 and Figure 11 , the first virtual triangle S1 includes a third virtual side L3 connecting two first sub-pixels 111 closest to and farthest from the virtual center point O, and the fourth virtual triangle S4 includes a fourth virtual side L4 connecting a first sub-pixel 111 closest to the virtual center point O and a second sub-pixel 121, and the third virtual side L3 is perpendicular to the fourth virtual side L4.

[0182] The two end points of the third virtual side L3 are the centers of the first red sub-pixel R1 and the third red sub-pixel R3, and the two end points of the fourth virtual side L4 are the centers of the first red sub-pixel R1 and the first green sub-pixel G1. The third virtual side L3 and the fourth virtual side L4 are perpendicular at the first red sub-pixel R1, that is, the angle between the line connecting the first green sub-pixel G1 and the first red sub-pixel R1 and the line connecting the third red sub-pixel R3 and the first red sub-pixel R1 is 90°.

[0183] As can be known from the foregoing, the first virtual triangle S1 is an equilateral triangle, so the angle at each of the three end points of the first virtual triangle S1 is 60°, that is, the angle at the third red sub-pixel R3 of the first virtual triangle S1 is 60°. On this basis, since the first virtual side L1 and the second virtual side L2 are perpendicular to each other, the angle between the line connecting the first green sub-pixel G1 and the third red sub-pixel R3 and the line connecting the second red sub-pixel R2 and the third red sub-pixel R3 is 90°. Therefore, it can be deduced that the angle between the line connecting the first green sub-pixel G1 and the third red sub-pixel R3 and the line connecting the first red sub-pixel R1 and the third red sub-pixel R3 is 30°.

[0184] In summary, the angle between the line connecting the first green sub-pixel G1 and the first red sub-pixel R1 and the line connecting the third red sub-pixel R3 and the first red sub-pixel R1 is 90°, and the angle between the line connecting the first green sub-pixel G1 and the third red sub-pixel R3 and the line connecting the first red sub-pixel R1 and the third red sub-pixel R3 is 30°. Therefore, the fifth virtual triangle formed by the first red sub-pixel R1, the first green sub-pixel G1 and the third red sub-pixel R3 is a right triangle with an angle of 30°, and the relationship among the distance between the first green sub-pixel G1 and the third red sub-pixel R3, the distance between the first green sub-pixel G1 and the first red sub-pixel R1 and the distance between the first red sub-pixel R1 and the third red sub-pixel R3 is 2:1:√3.

[0185] In some embodiments, the first virtual triangle S1 and the fourth virtual triangle S4 can be equilateral triangles at the same time, and the distance between the first red sub-pixel R1 and the third red sub-pixel R3 is the side length M of the first virtual triangle S1, and the distance between the first green sub-pixel G1 and the third red sub-pixel R3 is the side length N of the fourth virtual triangle S4. Therefore, in some embodiments, M and N satisfy:

[0186] It should be noted that the side length relationship between the second virtual triangle S2 and the fourth virtual triangle S4 can be the same as the side length relationship between the first virtual triangle S1 and the fourth virtual triangle S4. Similarly, the side length relationship between the third virtual triangle S3 and the fourth virtual triangle S4 can be the same as the side length relationship between the first virtual triangle S1 and the fourth virtual triangle S4, which is not limited in the embodiments of the present application.

[0187] In addition, since the fourth virtual triangle S4 can be an equilateral triangle, the distance between the center of the first blue sub-pixel B1 and the center of the first green sub-pixel G1 can be equal to the distance between the center of the first green sub-pixel G1 and the center of the first red sub-pixel R1. Since the distance between the center of the first green sub-pixel G1 and the center of the third red sub-pixel R3 can be twice the distance between the center of the first red sub-pixel R1 and the center of the first green sub-pixel G1, the distance between the center of the first blue sub-pixel B1 and the center of the first green sub-pixel G1 can be equal to the distance between the center of the first blue sub-pixel B1 and the center of the third red sub-pixel R3, i.e. the center of the first blue sub-pixel B1 can be located at the central position of the center of the first green sub-pixel G1 and the center of the third red sub-pixel R3.

[0188] Please refer to Figure 1 and Figure 8The fourth virtual connecting line D2 is used to connect the centers of two first sub-pixels 111 located in the same row, in other words, the length of the fourth virtual connecting line D2 is the distance between the two pixel groups 100 located in the same row. In some embodiments, the length of the fourth virtual connecting line D2 can be 2M, that is, twice the length of the side of the first virtual triangle S1.

[0189] In some embodiments, referring to Figure 8 and Figure 12 The third sub-pixel 131 located at the position closest to the virtual center point O is located on the angle bisector of one angle of the first virtual triangle S1.

Since the first virtual triangle S1 is an equilateral triangle, the first blue sub-pixel B1 located on the angle bisector also means that the distance between the center connecting line of the first blue sub-pixel B1 and the first red sub-pixel R1 and the distance between the center connecting line of the first blue sub-pixel B1 and the third red sub-pixel R3 are the same.

[0191] Further optionally, the first red sub-pixel R1 is located on the angle bisector of the included angle formed by the center connecting line of the first green sub-pixel G1 and the third green sub-pixel G3 and the center connecting line of the second green sub-pixel G2 and the third green sub-pixel G3, that is, on the angle bisector of one angle of the second virtual triangle S2.

[0194] Similarly, in some embodiments, the second sub-pixel 121 is arranged on the virtual connecting line of the second virtual point O2 and the third virtual point O3.

[0195] The first green sub-pixel G1 can be located on a virtual line connecting the second virtual point O2 and the third virtual point O3, wherein a distance between the second virtual point O2 and a center of the first green sub-pixel G1 can be greater than a distance between the third virtual point O3 and the center of the first green sub-pixel G1, or can be less than or equal to the distance between the third virtual point O3 and the center of the first green sub-pixel G1, which is not limited in the embodiments of the present application.

[0196] Similarly, in some embodiments, a third sub-pixel 131 is arranged on a virtual line connecting the first virtual point O1 and the third virtual point O3.

[0197] The first blue sub-pixel B1 can be located on a virtual line connecting the first virtual point O1 and the third virtual point O3, wherein a distance between the first virtual point O1 and a center of the first blue sub-pixel B1 can be greater than a distance between the third virtual point O3 and the center of the first blue sub-pixel B1, or can be less than or equal to the distance between the third virtual point O3 and the center of the first blue sub-pixel B1, which is not limited in the embodiments of the present application.

[0198] In some embodiments, as shown in FIG. 1A and FIG. 1B, a second sub-pixel 121 is arranged on an extension line of a line connecting the first virtual point O1 and the second virtual point O2, and the second sub-pixel 121 is located on a side of the second virtual point O2 away from the first virtual point O1. Figure 8 and Figure 13 In some embodiments, as shown in FIG. 1A and FIG. 1B, a second sub-pixel 121 is arranged on an extension line of a line connecting the first virtual point O1 and the second virtual point O2, and the second sub-pixel 121 is located on a side of the second virtual point O2 away from the first virtual point O1.

[0199] The center of the third green sub-pixel G3 can be located on an extension line of a virtual line connecting the first virtual point O1 and the second virtual point O2, and further, the first virtual point O1, the center of the first red sub-pixel R1, the second virtual point O2 and the center of the third green sub-pixel G3 are located on the same straight line, so that the pixel arrangement structure can be further optimized, the arrangement is more regular, and the display effect is improved.

[0200] In some embodiments, a third sub-pixel 131 is arranged on an extension line of a line connecting the second virtual point O2 and the third virtual point O3, and the third sub-pixel 131 is located on a side of the third virtual point O3 away from the second virtual point O2.

[0202] In some embodiments, a first sub-pixel 111 is disposed on an extension line of the connecting line of the first virtual point O1 and the third virtual point O3, and the first sub-pixel 111 is located on a side of the first virtual point O1 away from the third virtual point O3.

[0203] The center of the second red sub-pixel R2 can be located on an extension line of the virtual connecting line of the first virtual point O1 and the third virtual point O3, and further, the third virtual point O3, the center of the first blue sub-pixel B1, the first virtual point O1, and the center of the second red sub-pixel R2 are all located on the same straight line, so that the pixel arrangement structure can be further optimized, the arrangement is more regular, and the display effect is improved.

[0204] In some embodiments, referring to Figure 8 and Figure 14 , the connecting direction of the first sub-pixel 111 closest to the virtual center point O and the second sub-pixel 121 closest to the virtual center point O is parallel to the connecting direction of the first virtual point O1 and the third virtual point O3.

[0205] The extension direction of the connecting line of the center of the first red sub-pixel R1 and the first green sub-pixel G1 is parallel to the extension direction of the connecting line of the first virtual point O1 and the third virtual point O3. The third direction Z can be parallel to the extension direction of the connecting line of the first virtual point O1 and the third virtual point O3, and thus the extension direction of the connecting line of the center of the first red sub-pixel R1 and the first green sub-pixel G1 can also be parallel to the third direction Z.

[0206] In some embodiments, as shown in Figure 8 and Figure 14 , the connecting direction of the second sub-pixel 121 closest to the virtual center point O and the third sub-pixel 131 closest to the virtual center point O is parallel to the connecting direction of the first virtual point O1 and the second virtual point O2.

[0207] The extension direction of the connecting line of the center of the first green sub-pixel G1 and the first blue sub-pixel B1 is parallel to the extension direction of the connecting line of the first virtual point O1 and the second virtual point O2. The first direction X can be parallel to the extension direction of the connecting line of the first virtual point O1 and the second virtual point O2, and thus the extension direction of the connecting line of the center of the first green sub-pixel G1 and the first blue sub-pixel B1 can also be parallel to the first direction X.

[0208] In some embodiments, as shown in Figure 8 and Figure 14 , the connecting direction of the first sub-pixel 111 closest to the virtual center point O and the third sub-pixel 131 closest to the virtual center point O is parallel to the connecting direction of the second virtual point O2 and the third virtual point O3.

[0209] The extension direction of the line connecting the centers of the first red sub-pixel R1 and the first blue sub-pixel B1 is parallel to the extension direction of the line connecting the second virtual point O2 and the third virtual point O3. The second direction Y can be parallel to the extension direction of the line connecting the second virtual point O2 and the third virtual point O3, and thus the extension direction of the line connecting the centers of the first red sub-pixel R1 and the first blue sub-pixel B1 can also be parallel to the second direction Y.

[0210] In some embodiments, referring to Figure 15 The first pixel group 110 includes four first sub-pixels 111, and the lines connecting the four first sub-pixels 111 form a first virtual quadrilateral S5.

[0211] In the embodiments of the present application, the first pixel group 110 can include four first sub-pixels 111. Similarly, the second pixel group 120 can also include four second sub-pixels 121, and the third pixel group 130 can also include four third sub-pixels 131. The lines connecting the centers of the four first sub-pixels 111 form a first virtual quadrilateral S5, and the first virtual point O1 is located in the first virtual quadrilateral S5. The first virtual point O1 can be located at the center of the first virtual quadrilateral S5, that is, the distance between each first sub-pixel 111 and the first virtual point O1 is the same.

[0212] By increasing the number of first sub-pixels 111 in the first pixel group 110 to four, the luminance of the color corresponding to the first sub-pixel 111 can be increased to a certain extent, and the maximum luminance difference between the first sub-pixel 111 and other color sub-pixels can be improved, thereby improving the display contrast.

[0213] In some embodiments, the first virtual quadrilateral S5 is a parallelogram.

[0214] In the embodiments of the present application, the length and extension direction of the line connecting any two first sub-pixels 111 in the first pixel group 110 are the same as the length and extension direction of the line connecting the other two first sub-pixels 111, thereby optimizing the arrangement of the plurality of first sub-pixels 111 in the first pixel group 110 and improving the corresponding display effect. Similarly, the centers of the four second sub-pixels 121 in the second pixel group 120 can also be connected to form a parallelogram, and the centers of the four third sub-pixels 131 in the third pixel group 130 can also be connected to form a parallelogram.

[0215] In some embodiments, the first virtual quadrilateral S5 is a rectangle.

[0216] In the embodiment of the present application, any two adjacent sides of the first virtual quadrilateral S5 are perpendicular to each other, so that the plurality of first sub-pixels 111 in the first pixel group 110 are arranged more regularly. Similarly, the centers of the four second sub-pixels 121 in the second pixel group 120 can also be connected to form a rectangle, and the centers of the four third sub-pixels 131 in the third pixel group 130 can also be connected to form a rectangle.

[0217] In some embodiments, as shown in Figure 5 , the first virtual quadrilateral S5 is a square.

[0218] In the embodiment of the present application, any two adjacent sides of the first virtual quadrilateral S5 are perpendicular to each other and have the same length, so that the plurality of first sub-pixels 111 in the first pixel group 110 are arranged more regularly. Similarly, the centers of the four second sub-pixels 121 in the second pixel group 120 can also be connected to form a square, and the centers of the four third sub-pixels 131 in the third pixel group 130 can also be connected to form a square.

[0219] In some embodiments, as shown in Figure 16 , the first pixel group 110, the second pixel group 120, and the third pixel group 130 are arranged separately from each other to form a wiring area Z therebetween.

[0220] Taking the first pixel group 110 and the second pixel group 120 as an example, the separate arrangement of the first pixel group 110 and the second pixel group 120 means that there is a gap between the first pixel group 110 and the second pixel group 120, and there is no other sub-pixel in the gap. The gaps formed by the first pixel group 110, the second pixel group 120, and the third pixel group 130 together form the wiring area Z.

[0221] In the corresponding display panel using the pixel arrangement structure in the embodiment of the present application, a wiring structure can be arranged in the corresponding wiring area Z to realize the conduction of the pixel circuit and meet the display needs. As known from the foregoing, the projection of the first sub-pixel 111 closest to the virtual center point O in the first direction X is located between the projections of the two second sub-pixels 121 in the first direction X, and the projection of the second sub-pixel 121 closest to the virtual center point O in the second direction Y is located between the projections of the two third sub-pixels 131 in the second direction Y. Therefore, the shape of the wiring area Z is difficult to be a regular rectangular structure, thereby reducing the degree of diffraction. That is, the embodiment of the present application can meet the wiring needs while improving the display effect.

[0222] In some embodiments, as shown in Figure 16As shown, the second pixel group includes a second virtual connection line D2 connecting the two second sub-pixels 121, and the first sub-pixel 111 at the position closest to the virtual center point O is arranged apart from the second virtual connection line D2 to form part of the wire area Z between the first sub-pixel 111 and the second virtual connection line.

[0223] The two ends of the second virtual connection line D2 are connected to the outer periphery of the two second sub-pixels 121, and the second virtual connection line D2 is arranged apart from the first sub-pixel 111, and together they form part of the wire area Z, and the shape of the second virtual connection line D2 and the shape of the first sub-pixel 111 can together define the shape of part of the wire area Z. For example, if the shape of the first sub-pixel 111 is a polygon, and the second virtual connection line D2 is a straight line structure, the wire area Z formed by the corresponding first sub-pixel 111 is a polyline channel. Of course, if the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 131 are circular, and the first virtual connection line D1, the second virtual connection line D2, and the third virtual connection line D3 are straight lines, they can also be implemented, at this time, the wire area Z is also a polyline channel. In the corresponding display panel, the wire will extend in a polyline. Compared with the scheme in which the wire area Z is a straight line channel, this design can reduce the degree of diffraction and improve the display effect.

[0224] It should be noted that the first pixel group can also have a first virtual connection line D1 connecting the outer periphery of the two first sub-pixels 111, and the first virtual connection line D1 can be arranged apart from the third sub-pixel 131 to form at least part of the wire area Z; the third pixel group can also have a third virtual connection line D3 connecting the outer periphery of the two third sub-pixels 131, and the third virtual connection line D3 can be arranged apart from the second sub-pixel 121 to form part of the wire area Z, and the first virtual connection line D1, the second virtual connection line D2, and the third virtual connection line D3 can be similar or identical in shape, or completely different, and the embodiments of the present application are not limited in this regard.

[0225] In some embodiments, referring to Figure 17 , the second virtual connection line D2 includes an arc segment.

[0226] Since the second virtual connection line D2 is an arc segment, part of the outer contour of the wire area Z is arc-shaped, and in the display panel, part of the wire can be arranged to extend in an arc shape, thereby effectively improving the diffraction problem and improving the display effect. Similarly, for example, the first virtual connection line D1 and the third virtual connection line D3 can also include an arc segment.

[0227] In some embodiments, the shape of the first sub-pixel 111 is circular.

[0228] As the same as the second virtual connection line D2, the shape of the first sub-pixel 111 can also affect the shape and size of the wire area Z. Since the shape of the first sub-pixel 111 is circular, the corresponding part of the outer contour of the wire area Z is also circular. In the display panel, part of the wire can be arranged to extend in an arc shape, thereby effectively improving the diffraction problem and improving the display effect. Similarly, the second sub-pixel 121 and the third sub-pixel 131 can also be circular.

[0229] In some embodiments, as shown in FIG. 1B, the wire area Z is in an "S" shape. Figure 17

[0230] The wire area Z is in a continuous curve structure. In the corresponding display panel, the wire can also be arranged in an S-shaped wire, thereby meeting the needs of wire arrangement and reducing the diffraction problem at the same time.

[0231] In some embodiments, the wire area Z is in an "S" shape with a constant width. That is, the width of the wire area Z is consistent, thereby improving the reliability of the structure of the wire area Z, ensuring the extension of the wire in the wire area Z in the display panel, and reducing the difficulty of wire preparation.

[0232] In some embodiments, as shown in FIG. 1C, the first pixel group 110 includes a first non-opening area A1 arranged between the plurality of first sub-pixels 111. Figure 18

[0233] The first non-opening area A1 mentioned in the embodiments of the present application refers to the area between the plurality of first sub-pixels 111 in the first pixel group 110, which does not have a pixel opening, that is, does not have a first sub-pixel 111 or a sub-pixel of other colors, thereby improving the transmittance of the display panel at the position corresponding to the first non-opening area A1 and meeting the needs of transparent display.

[0234] The conventional transparent display panel usually reduces the size of the pixel opening or reduces the number of pixel openings, thereby increasing the distance between adjacent pixels to increase the area of the transparent region and meet the needs of transparent display. The embodiments of the present application arrange the plurality of first sub-pixels 111 around the first virtual point, thereby forming the first non-opening area A1 at the position of the first virtual point and realizing the concentration of the transparent region of the display panel. Compared with the conventional transparent display panel, the embodiments of the present application only adjust the pixel arrangement structure to form a non-opening area between the plurality of first sub-pixels 111 that can realize the transparent effect, thereby meeting the needs of transparent display without changing the size of the pixel opening and the pixel density and effectively utilizing the space.

[0235] ​​Similarly, in some embodiments, the second pixel group 120 includes a second non-opening region A2 disposed between the plurality of second sub-pixels 121. In other embodiments, the third pixel group 130 includes a third non-opening region A3 disposed between the plurality of third sub-pixels 131.

[0236] In addition, in some special scenarios, the corresponding pixel circuit can be disposed in the first non-opening region A1 according to the use requirement, and the anode in the first sub-pixel 111 is replaced with a transparent material, so that the double-sided display effect can be realized.

[0237] In some embodiments, the distance between any adjacent virtual center points O is equal.

[0238] The pixel arrangement structure includes a plurality of pixel units 100, and the virtual center points O correspond to the center positions of the pixel units 100, that is, the positional relationship between different virtual center points O determines the positional relationship between the corresponding pixel units 100. On this basis, the embodiments of the present application set the distance between any adjacent virtual center points O to be equal, so that the relative distance between any adjacent pixel units 100 remains the same, thereby realizing the regular arrangement of the plurality of pixel units 100, which is beneficial to improve the display effect.

[0239] The second aspect, as shown in Figure 17 and Figure 18 The embodiments of the present application also provide another pixel arrangement structure, which includes a plurality of repeatedly arranged pixel units 100, and the pixel unit 100 includes a first pixel group 110, a second pixel group 120 and a third pixel group 130 around a virtual center point O. The first pixel group 110 includes a plurality of first sub-pixels 111.

[0240] The plurality of first sub-pixels 111 are arranged at intervals around the first virtual point to form a first transparent region centered on the first virtual point between the plurality of first sub-pixels 111; the second pixel group 120 includes a plurality of second sub-pixels 121, and the plurality of second sub-pixels 121 are arranged at intervals around the second virtual point to form a second transparent region centered on the second virtual point between the plurality of second sub-pixels 121; the third pixel group 130 includes a plurality of third sub-pixels 131, and the plurality of third sub-pixels 131 are arranged at intervals around the third virtual point to form a third transparent region centered on the third virtual point between the plurality of third sub-pixels 131.

[0241] The first pixel group 110, the second pixel group 120 and the third pixel group 130 are arranged separately from each other to form a wiring region Z therebetween.

[0242] The first transparent region corresponds to the first non-opening region A1, the second transparent region corresponds to the second non-opening region A2, and the third transparent region corresponds to the third non-opening region A3. In the embodiment of the present application, the first sub-pixels 111 are arranged around the first virtual point, so that the first transparent region can be formed at the position of the first virtual point; the second sub-pixels 121 are arranged around the second virtual point, so that the second transparent region can be formed at the position of the second virtual point; and the third sub-pixels 131 are arranged around the third virtual point, so that the third transparent region can be formed at the position of the third virtual point. This design can realize the concentrated arrangement of the transparent regions in the display panel, and meet the requirement of high transmittance of the corresponding display panel.

[0243] As shown in FIG. 1, in the row direction, the first sub-pixels 111, the third sub-pixels 131 and the second sub-pixels 121 are arranged in three rows respectively. The density of the first and third rows is the same, and the density of the second row is twice that of the first row. The arrangement of the first sub-pixels 111, the third sub-pixels 131 and the second sub-pixels 121 in the three consecutive rows is staggered with each other, and the arrangement is inclined. Figure 1 In the column direction, the pixels are arranged in several columns. The arrangement of the odd columns is the same, the arrangement of the even columns is staggered with the arrangement of the odd columns, and the density of the even columns is twice that of the odd columns.

[0244] In addition, in the embodiment of the present application, the first pixel group 110, the second pixel group 120 and the third pixel group 130 are arranged separately from each other to form the wiring region Z therebetween, so that in the corresponding display panel using the pixel arrangement structure in the embodiment of the present application, a wiring structure can also be arranged in the corresponding wiring region Z, so as to realize the conduction of the pixel circuit and meet the display requirement.

[0245] In some embodiments, the wiring region Z includes arc-shaped paths which are the same in shape and radiate from the virtual center point to the first direction X, the second direction Y and the third direction Z. The included angles between the first direction X, the second direction Y and the third direction Z are the same as each other, and the included angle between any two directions is 120°. For example, the arc-shaped paths can also be polyline paths. At this time, the boundary between the transparent region and the non-transparent region is a straight line, for example

[0246] Figure 16

[0247] The wiring region Z is an arc-shaped structure formed by radiation with the virtual center point O as the center, which is similar to a fan blade structure, and each arc-shaped structure extends to the first direction X, the second direction Y and the third direction Z respectively. Compared with the traditional matrix wiring mode, the wiring is in a curve form, so that the wiring is more flexible and can meet the wiring requirement in the case of high resolution. At the same time, this design can also effectively improve the diffraction problem and improve the display effect.

[0248] In the second aspect, please refer to Figure 19 ​​The display panel provided by the embodiments of the present application has the beneficial effects of the pixel arrangement structure in any of the foregoing embodiments. For details, refer to the foregoing description of the pixel arrangement structure, which will not be repeated here.

[0249] It should be noted that the display panel provided by the embodiments of the present application has the beneficial effects of the pixel arrangement structure in any of the foregoing embodiments. For details, refer to the foregoing description of the pixel arrangement structure, which will not be repeated here.

[0250] In some embodiments, referring to Figure 20 , the display panel further includes a light-transmitting material layer, and the light-transmitting material layer includes a light-transmitting material portion 20. In the thickness direction of the display panel, at least part of the light-transmitting material portion 20 is located in the first pixel group 110.

[0251] The light-transmitting material portion 20 is a material with high transmittance, so as to improve the transmittance of the display panel at the corresponding position. On this basis, at least part of the light-transmitting material portion 20 is located in the first pixel group 110, and further, at least part of the light-transmitting material portion 20 is located in the first non-opening area A1, so that the area located between the plurality of first sub-pixels 111 can have a higher transmittance, improve the transmittance of the display panel, and meet the needs of light-transmitting display. The light-transmitting material portion 20 can be disposed in the same layer as at least part of the film layers in the first sub-pixel 111, or can be completely located in different film layers from the first sub-pixel 111, which is not limited in the embodiments of the present application.

[0252] In some embodiments, referring to Figure 21 , the light-transmitting material portion 20 is disposed in the same layer as at least part of the film layers in the first sub-pixel 111.

[0253] The first sub-pixel 111 is formed by stacking a plurality of film layers. For example, the first sub-pixel 111 includes a cathode layer, an anode layer, a hole injection layer, a hole transport layer, an electron injection layer, and an electron transport layer. The light-transmitting material portion 20 can be disposed in the same layer as one of the layers, so as to reduce the occupation of the light-transmitting material layer on the thickness dimension of the display panel, and be beneficial to lightening.

[0254] In addition, in some embodiments, in the thickness direction of the display panel, at least part of the light-transmitting material portion 20 is located in at least one of the second pixel group and the third pixel group. That is, at least part of the light-transmitting material portion 20 can be located in the second non-opening area or the third non-opening area, so as to further improve the transmittance of the display panel and meet the needs of transparent display.

[0255] In some embodiments, as shown in Figure 20 , the display panel further includes a driving wire 30 disposed between any two of the first pixel group 110, the second pixel group 120, and the third pixel group 130.

[0256] The driving wire 30 is used to control the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 to realize the light-emitting function. In order to reduce the difficulty of arranging the driving wire 30 and reduce the risk of signal transmission delay caused by the too long length of the driving wire 30, the embodiment of the present application sets the driving wire 30 between any two of the first pixel group 110, the second pixel group 120 and the third pixel group 130, so as to reduce the distance between the driving wire 30 and the corresponding sub-pixel and improve the reliability of signal transmission.

[0257] In some embodiments, as shown in Figure 20 The light-transmitting material part 20 includes the edge part 21, and the edge part 21 includes an arc-shaped segment.

[0258] In order to improve the light-transmitting effect, it is necessary to avoid the overlap between the driving wire 30 and the light-transmitting material part 20 as much as possible, so the driving wire 30 is located between adjacent light-transmitting material parts 20. As known from the foregoing, the light-transmitting material part 20 is located between the plurality of first sub-pixels 111, so the edge part 21 of the light-transmitting material part 20 is generally coincident with the first virtual connection line D1 connecting two first sub-pixels 111.

[0259] On this basis, the embodiment of the present application sets the edge part 21 of the light-transmitting material part 20 with an arc-shaped segment, so that the driving wire 30 located between adjacent light-transmitting material parts 20 can extend in a curve form, meeting the needs of wire arrangement and light-transmitting of the display panel. In some embodiments, the driving wire 30 can include a curve segment.

[0260] In a fourth aspect, referring to Figure 22 The embodiment of the present application provides a mask assembly for forming the pixel arrangement structure in any of the foregoing embodiments. The mask assembly includes a first mask plate 40, and the first mask plate 40 includes a first mask opening 41 matched with the first pixel group, and the first mask opening 41 is set in a communication form corresponding to the plurality of first sub-pixels in the first pixel group.

[0261] The first mask opening 41 on the first mask plate 40 can correspond to the shape and size of the plurality of first sub-pixels in the first pixel group at the same time. For example, when the first sub-pixel is a circular structure, the edge of the first mask opening 41 includes an arc-shaped structure; when the first sub-pixel is a square structure, the edge of the first mask opening 41 includes a polyline structure.

[0262] Meanwhile, in the embodiment of the present application, the first mask opening 41 corresponds to the structure of the first pixel group. This design can simultaneously evaporate multiple first sub-pixels in one mask opening, thereby reducing the difficulty of evaporation. In the embodiment, the first mask opening 41 is designed in a substantially "pin" shape, which corresponds to the structure of the three first sub-pixels 111, so as to simultaneously evaporate three sub-pixels of the same color.

[0263] Similarly, the mask support can also include a second mask plate, the second mask plate includes a second mask opening corresponding to the second sub-pixel, and multiple second pixel openings corresponding to multiple second sub-pixels in the second pixel group are arranged in communication with each other.
