Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a pixel arrangement structure, a display panel, and a display device. Background Technology

[0002] With the rapid development of electronic devices, users have increasingly higher requirements for display panels, especially for display effects. Current display panels often have low aperture ratios. Extremely low aperture ratios lead to increased pixel current density, causing insufficient darkness in low-light conditions. Summary of the Invention

[0003] This application provides a pixel arrangement structure, a display panel, and a display device, which aim to improve the pixel aperture ratio of the display panel.

[0004] An embodiment of the first aspect of this application provides a pixel arrangement structure, which includes a plurality of repeating units arranged along a first direction and a second direction, the first direction and the second direction intersecting. The repeating units include a first pixel group and a second pixel group, which are arranged along the first direction. Each of the first pixel group and the second pixel group includes a display unit, and the display unit includes a plurality of sub-pixels, including a first sub-pixel, a second sub-pixel, and a third sub-pixel. The ratio of the number of the first sub-pixel, the second sub-pixel, and the third sub-pixel in the first pixel group and the second pixel group is 1:1:1. In the display unit, at least two sub-pixels are distributed along the first direction, and at least two sub-pixels are distributed along the second direction. The first pixel group includes at least two display units. In two adjacent display units in the first pixel group, a sub-pixel of one display unit and a sub-pixel of the other display unit are distributed along the second direction.

[0005] The second aspect of this application also provides a display panel, including the pixel arrangement structure of any of the first aspect embodiments described above.

[0006] The third aspect of this application also provides a display device, including the display panel of any of the second aspect embodiments described above.

[0007] In the pixel arrangement structure provided in this application embodiment, the pixel arrangement structure includes multiple repeating units arranged along a first direction and a second direction. That is, the pixel arrangement structure can be obtained by repeatedly arranging the repeating units along the first direction and the second direction. The repeating units include a first pixel group and a second pixel group arranged along the first direction. Both the first pixel group and the second pixel group include display units. The multiple sub-pixels of the display unit include a first sub-pixel, a second sub-pixel, and a third sub-pixel, so that both the first pixel group and the second pixel group can form a complete display unit for emitting white light, which can ensure the display effect. The ratio of the number of the first sub-pixel, the second sub-pixel, and the third sub-pixel is 1:1:1, that is, there are no shared pixels in the display unit, which can ensure the display effect. In the two display units of the first pixel group, one sub-pixel of one display unit and one sub-pixel of the other display unit are distributed along the second direction, which can reduce the distribution area of ​​at least two display units in the first pixel group and increase the distribution density of sub-pixels in the first pixel group. Therefore, when the pixel arrangement structure is used in a display panel, it can improve the pixel aperture ratio of the display panel. Attached Figure Description

[0011] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the embodiments of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly.

[0014] Figure 1 This is a schematic diagram of a pixel arrangement structure provided by related technologies. The pixel arrangement structure includes multiple display units 20', each display unit 20' including a first sub-pixel 31', a second sub-pixel 32', and a third sub-pixel 33'. The centers of the first sub-pixel 31', the second sub-pixel 32', and the third sub-pixel 33' in the display unit 20' are located at the three vertices of an equilateral triangle.

[0015] In related technologies, to improve the transmittance and optimize the power consumption of display panels, color filter substrates are directly placed on the sub-pixels of the display panel. The color filter substrate includes a light-shielding part and a light-filtering unit, with the light-filtering unit corresponding to each sub-pixel, capable of filtering stray light and improving the display effect. Under current process conditions, the pixel aperture superimposed on the color filter substrate leads to a drastically reduced aperture ratio. This extremely low aperture ratio results in an increased pixel current density, causing the display panel to not be dark enough in dark conditions. In some related technical solutions, to reduce the brightness of the display panel in dark conditions, the voltage of some voltage signal lines, such as ground power signal lines, voltage reference signal lines, and high-level voltage signal lines, is pulled very low, even exceeding the limits set by the hyper-integrated chip, severely affecting the display effect.

[0016] To address the aforementioned technical problems, embodiments of this application provide a pixel arrangement structure, a display panel, and a display device, which can significantly improve the aperture ratio of the display panel and thereby reduce the brightness of the display panel in the dark state.

[0017] To better understand this application, the following will be combined with... Figures 2 to 13The pixel arrangement structure, display panel, and display device of the embodiments of this application will be described in detail.

[0018] Figure 2 This is a schematic diagram of a pixel arrangement structure provided in an embodiment of this application. Figure 3 yes Figure 2 A schematic diagram of the structure of a repeating unit in one example.

[0019] like Figure 2 and Figure 3 As shown, an embodiment of the first aspect of this application provides a pixel arrangement structure, which includes a plurality of repeating units 10 arranged along a first direction X and a second direction Y, the first direction X and the second direction Y intersecting. The repeating unit 10 includes a first pixel group 11 and a second pixel group 12, which are arranged along the first direction X. Both the first pixel group 11 and the second pixel group 12 include a display unit 20, and the display unit 20 includes a plurality of sub-pixels 30. The sub-pixels 30 include a first sub-pixel 31, a second sub-pixel 32, and a third sub-pixel 33. Pixel 33, and in the first pixel group 11 and the second pixel group 12, the ratio of the number of the first sub-pixel 31, the second sub-pixel 32 and the third sub-pixel 33 is 1:1:1; in the display unit 20, at least two sub-pixels 30 are distributed along the first direction X and at least two sub-pixels 30 are distributed along the second direction Y; the first pixel group 11 includes at least two display units 20, and in two adjacent display units 20 in the first pixel group 11, a sub-pixel 30 of one display unit 20 and a sub-pixel 30 of the other display unit 20 are distributed along the second direction Y.

[0020] In the pixel arrangement structure provided in this application embodiment, the pixel arrangement structure includes multiple repeating units 10 arranged along the first direction X and the second direction Y. That is, the pixel arrangement structure can be obtained by repeatedly arranging the repeating units 10 along the first direction X and the second direction Y. The repeating unit 10 includes a first pixel group 11 and a second pixel group 12 arranged along the first direction X. Both the first pixel group 11 and the second pixel group 12 include a display unit 20. The multiple sub-pixels 30 of the display unit 20 include a first sub-pixel 31, a second sub-pixel 32, and a third sub-pixel 33, so that the first pixel group 11 and the second pixel group 12 can each form a complete display unit 20 for emitting white light, which can ensure the display effect. The ratio of the number of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 is 1:1:1, that is, there are no shared pixels in the display unit 20, which can ensure the display effect. In the two display units 20 of the first pixel group 11, a sub-pixel 30 of one display unit 20 and a sub-pixel 30 of the other display unit 20 are distributed along the second direction Y, such as Figure 2The overlapping of a portion of two adjacent display units 20 along the second direction Y can reduce the distribution area of ​​at least two display units 20 in the first pixel group 11 and increase the distribution density of sub-pixels 30 in the first pixel group 11. As a result, when the pixel arrangement structure is used in the display panel, the pixel aperture ratio of the display panel can be improved.

[0021] The first direction X and the second direction Y need to intersect, for example, the first direction X and the second direction Y can be perpendicular. Optionally, the repeating units 10 are aligned along the first direction X and the second direction Y, that is, the centers of two adjacent repeating units 10 along the first direction X and / or the second direction Y are aligned, which can simplify the distribution pattern of the pixel arrangement structure and facilitate the preparation of multiple sub-pixels 30.

[0022] Optionally, the ratio of the number of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 in the display unit 20 is 1:1:1, so that the display unit 20 can be used to emit white light. In the first pixel group 11 and the second pixel group 12, the ratio of the number of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 is 1:1:1, so that an integer number of display units 20 can be formed in both the first pixel group 11 and the second pixel group 12.

[0023] Optionally, the first sub-pixel 31 is used to emit red light, the second sub-pixel 32 is used to emit green light, and the third sub-pixel 33 is used to emit blue light. In other embodiments, the first sub-pixel 31 can also be used to emit green or blue light, the second sub-pixel 32 can also be used to emit red or blue light, and the third sub-pixel 33 can also be used to emit red or green light.

[0024] Optionally, the distribution areas of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 can be the same, so that the light output of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 is similar, and the white light emitted by the display unit 20 formed by the combination of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 is less prone to color shift. Alternatively, when the third sub-pixel 33 is used to emit blue light, the distribution area of ​​the third sub-pixel 33 can be larger than the distribution areas of the first sub-pixel 31 and the second sub-pixel 32 to compensate for the problem of insufficient display brightness of the blue sub-pixel 30 due to the limitation of blue light-emitting material. In other embodiments, the user can adjust the distribution areas of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 according to actual needs. This application does not limit the specific ratio of the distribution areas of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33.

[0025] Optionally, the shapes of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 can be circular, elliptical, polygonal, etc. For example, if the shapes of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 are circular, it is difficult for strip-shaped gaps to form between two adjacent sub-pixels 30, which can improve the diffraction problem of light and improve the display effect.

[0026] Optionally, the first pixel group 11 may include two display units 20, and the second pixel group 12 may include one display unit 20. This embodiment of the application uses the example of the first pixel group 11 including two display units 20 and the second pixel group 12 including one display unit 20 for illustration. In other embodiments, the first pixel group 11 may also include three or more display units 20, and the second pixel group 12 may also include multiple display units 20.

[0027] Taking the first pixel group 11 as an example, which includes two display units 20, the two display units 20 in the first pixel group 11 are the first display unit 20a and the second display unit 20b, respectively. Figure 2 and Figure 3 As shown, each display unit 20 may include a first sub-pixel 31, a second sub-pixel 32, and a third sub-pixel 33. The first sub-pixel 31 and the second sub-pixel 32 may be distributed along the second direction Y to form a first pixel column 41. The third sub-pixel 33 and the first pixel column 41 are distributed along the first direction X. The third sub-pixel 33 of the first display unit 20a and the second display unit 20b are distributed along the second direction Y to form a second pixel column 42. Alternatively, as... Figure 4a and Figure 4 As shown, in the repeating unit 10, the first sub-pixel 31 and the second sub-pixel 32 of the first display unit 20a are distributed along the second direction Y to form a pixel column 40. The third sub-pixel 33 of the first display unit 20a and the first sub-pixel 31 of the second display unit 20b are distributed along the second direction Y to form another pixel column 40. The second sub-pixel 32 and the third sub-pixel 33 of the second display unit 20b are distributed along the second direction Y to form yet another pixel column 40. In this embodiment, the six sub-pixels 30 of the two display units 20 can be arranged in two rows and three columns, which can reduce the distribution area of ​​the two display units 20 and improve the pixel aperture ratio.

[0028] like Figure 1 As shown, in related technologies, two display units 20' are arranged side-by-side along the first direction X and occupy the area of ​​the original two pixels. For example... Figures 2 to 4 As shown in the embodiment of this application, since one of the sub-pixels 30 of two adjacent display units 20 in the first pixel group 11 is distributed along the second direction Y, and a portion of the two adjacent display units 20 overlaps, the two display units 20 can occupy the original area of ​​1.5 pixels, thereby effectively improving the pixel aperture ratio.

[0029] Figures 1 to 4 A solid line frame indicates the range of one pixel, but this solid line frame does not constitute a structural limitation on the pixel arrangement structure of the embodiments of this application. Dashed lines frame the ranges of the first pixel group 11, the second pixel group 12, and the display unit 20, but these dashed lines also do not constitute a structural limitation on the pixel arrangement structure of the embodiments of this application. In the embodiments of this application, the pixel arrangement structure refers to the relative positional relationship of multiple sub-pixels 30.

[0030] In some alternative embodiments, such as Figures 2 to 4 As shown, the ratio of the number of the first pixel group 11 and the second pixel group 12 in the repeating unit 10 is 2:1.

[0031] The sub-pixels 30 of two adjacent display units 20 within the first pixel group 11 are distributed along the second direction Y, and the pixel density of the first pixel group 11 is relatively large. In these optional embodiments, making the number of the first pixel group 11 greater than the number of the second pixel group 12 can effectively improve the aperture ratio of the pixels within the repeating unit 10, thereby improving the pixel aperture ratio of the entire pixel arrangement structure.

[0032] Optionally, this application embodiment illustrates the repetition unit 10 by including two first pixel groups 11 and one second pixel group 12. In other embodiments, the repetition unit 10 may also include four first pixel groups 11 and two second pixel groups 12.

[0033] Optionally, the two first pixel groups 11 and one second pixel group 12 within the repeating unit 10 are distributed along the first direction X, as follows: Figures 2 to 4 As shown, the second pixel group 12 can be located on one side of the two first pixel groups 11, or, as... Figure 5 and Figure 6 As shown, the second pixel group 12 can be located between two first pixel groups 11. That is, multiple first pixel groups 11 within the repeating unit 10 are adjacent along the first direction X, or the second pixel group 12 within the repeating unit 10 is located between two adjacent first pixel groups 11.

[0034] In some alternative embodiments, such as Figures 2 to 8 As shown, the number of sub-pixels 30 in the first pixel group 11 is twice the number of sub-pixels 30 in the second pixel group 12; the projected area of ​​the first pixel group 11 along the third direction Z is 1.5 times the projected area of ​​the second pixel group 12 along the third direction Z, and the third direction Z is perpendicular to the plane containing the second direction Y and the first direction X.

[0035] In these optional embodiments, the number of sub-pixels 30 in the first pixel group 11 is twice the number of sub-pixels 30 in the second pixel group 12, but the projected area of ​​the first pixel group 11 is 1.5 times the projected area of ​​the second pixel group 12. Therefore, the density of sub-pixels 30 in the first pixel group 11 is higher. The larger number of first pixel groups 11 in the repeating unit 10 can effectively improve the aperture ratio of the entire repeating unit 10, thereby improving the aperture ratio of the pixel arrangement structure.

[0036] Optional, such as Figures 2 to 6 As shown, the first pixel group 11 and the second pixel group 12 have the same size in the second direction Y. Optionally, the size of the first pixel group 11 in the first direction X is 1.5 times the size of the second pixel group 12 in the first direction X, that is, the sum of the sizes of the two first pixel groups 11 in the repeating unit 10 in the first direction X is 3 times the size of the second pixel group 12 in the first direction X. For example, when the six sub-pixels 30 of the two display units 20 in the first pixel group 11 are arranged in 2 rows and 3 columns, the three sub-pixels 30 in the second pixel group 12 are arranged in 2 rows and 2 columns, with one column having two sub-pixels 30 and the other column having one sub-pixel 30.

[0037] Taking the first pixel group 11 as an example, which includes two display units 20, and each display unit 20 includes a first sub-pixel 31, a second sub-pixel 32, and a third sub-pixel 33, in some optional embodiments, such as Figure 2 and Figure 3 As shown, the first pixel group 11 includes a first pixel column 41 and a second pixel column 42. The first pixel column 41 includes a first sub-pixel 31 and a second sub-pixel 32 distributed along the second direction Y; the second pixel column 42 includes two third sub-pixels 33 distributed along the second direction Y. The second pixel column 42 is located between the two first pixel columns 41 arranged along the first direction X.

[0038] Figure 3 The dashed boxes in the figure indicate the range of the first pixel column 41 and the second pixel column 42. The dashed boxes do not constitute a structural limitation on the pixel arrangement structure of the embodiments of this application.

[0039] In these optional embodiments, the first pixel group 11 includes six sub-pixels 30. The first sub-pixels 31 and the second sub-pixels 32 among the six sub-pixels 30 are arranged along the second direction Y to form a first pixel column 41, and the first pixel group 11 includes two first pixel columns 41. The two third sub-pixels 33 among the six sub-pixels 30 are arranged along the second direction Y to form a second pixel column 42, and the first pixel group 11 includes one second pixel column 42. The second pixel column 42 is located between the two first pixel columns 41, which can reduce the distance between the first sub-pixels 31, the second sub-pixels 32 and the third sub-pixels 33 in the display unit 20, improve the display effect of the unit display unit 20, and thus improve the display effect of the entire pixel arrangement structure.

[0040] Optionally, the first sub-pixel 31 and the second sub-pixel 32 within the second pixel group 12 can be distributed along the second direction Y, and the third sub-pixel 33 is located on one side of the first sub-pixel 31 and the second sub-pixel 32 in the second direction Y. That is, within the first pixel group 11 and the second pixel group 12, both the first sub-pixel 31 and the second sub-pixel 32 are distributed along the second direction Y, making the arrangement pattern of the second pixel group 12 similar to that of the first pixel group 11, which can reduce the display difference between the first pixel group 11 and the second pixel group 12 and improve the uniformity of the display.

[0041] In some other alternative embodiments, such as Figure 4 As shown, the first pixel group 11 includes n pixel columns 40, and each pixel column 40 includes two sub-pixels 30 distributed along the second direction Y. The sub-pixels 30 within the same pixel column 40 have different emission colors, and n≥3. Figure 4 The range of pixel column 40 is indicated by a dashed box, but the dashed box does not constitute a structural limitation on the pixel arrangement structure of the embodiments of this application.

[0042] In these optional embodiments, the multiple sub-pixels 30 within the first pixel group 11 are distributed in two rows and n columns, and the sub-pixels 30 within the same pixel column 40 emit different colors. For example, two sub-pixels 30 within the same pixel column 40 may be the first sub-pixel 31 and the second sub-pixel 32, or two sub-pixels 30 within the same pixel column 40 may be the third sub-pixel 33 and the first sub-pixel 31, or two sub-pixels 30 within the same pixel column 40 may be the second sub-pixel 32 and the third sub-pixel 33. Sub-pixels 30 with the same emission color are not located in the same pixel column 40, which can improve obvious monochromatic display stripes and enhance the display effect of the display panel.

[0043] Optional, such as Figures 3 to 4As shown, the first sub-pixel 31 and the second sub-pixel 32 of the second pixel group 12 are arranged along the second direction Y to form a third pixel column 43, and the third sub-pixel 33 in the second pixel column 42 is located in the fourth pixel column 44. The third sub-pixel 33 in the first pixel group 11 and the third sub-pixel 33 in the second pixel group 12 are not adjacent along the first direction X. For example, as Figures 3 to 4 As shown, within the repeating unit 10, two first pixel groups 11 are arranged adjacently, and the fourth pixel column 44 of the second pixel group 12 is located on the side of the third pixel column 43 facing away from the first pixel group 11. Alternatively, as... Figure 5 As shown, the second pixel group 12 is located between the two first pixel groups 11. The two sub-pixels 30 in the pixel column 40 adjacent to the fourth pixel column 44 are the first sub-pixel 31 and the second sub-pixel 32. This makes the distance between the third sub-pixel 33 in the first pixel group 11 and the third sub-pixel 33 in the second pixel group 12 relatively large, making it less likely to form obvious display stripes and improving the display effect.

[0044] In some alternative embodiments, such as Figure 4 As shown, within the same first pixel group 11, two adjacent sub-pixels 30 along the first direction X emit different colors. Combined with the aforementioned difference in the emission colors of sub-pixels 30 within the same pixel column 40, this results in different emission colors for two adjacent sub-pixels 30 along the first direction X or along the second direction Y within the same first pixel group 11. This makes the distribution of multiple sub-pixels 30 more uniform, resulting in a more consistent display effect.

[0045] In some alternative embodiments, please continue to refer to Figure 4 Within the same repeating unit 10, two adjacent sub-pixels 30 along the first direction X emit different colors. The emission colors of two adjacent sub-pixels 30 along the first direction X in the second pixel group 12 are different from those in the first pixel group 11. For example, the second pixel group 12 includes the aforementioned third pixel column 43 and fourth pixel column 44. The arrangement of the pixel column 40 adjacent to the third pixel column 43 in the first pixel group 11 is different from that of the third pixel column 43, so that the emission colors of two adjacent sub-pixels 30 along the first direction X are different, making the distribution of sub-pixels 30 of different colors more even and improving the uniformity of the display effect.

[0046] In some alternative embodiments, such as Figures 2 to 6 As shown, the second pixel group 12 includes the third pixel column 43 and the fourth pixel column 44 mentioned above. The third pixel column 43 and the fourth pixel column 44 are arranged along the first direction X, and the projection of the third sub-pixel 33 of the fourth pixel column 44 along the first direction X corresponds to the projection between the first sub-pixel 31 and the second sub-pixel 32 along the first direction X.

[0047] In these optional implementations, the third sub-pixel 33 of the fourth pixel column 44 is located between the first sub-pixel 31 and the second sub-pixel 32, which can reduce the distance between the third sub-pixel 33 and the first sub-pixel 31 and the second sub-pixel 32, thereby improving the display effect of the display unit 20.

[0048] like Figures 1 to 8 As shown, an embodiment of the second aspect of this application also provides a display panel, including the pixel arrangement structure provided in any of the first aspect embodiments described above.

[0049] Since the display panel provided in this application embodiment includes the pixel arrangement structure of any of the above embodiments, the display panel in this application embodiment has the beneficial effects of any of the above pixel arrangement structures. A larger pixel aperture ratio can reduce pixel current density and improve the problem of insufficient darkness in the display panel. This application solves the problem of insufficient darkness in the dark state by increasing the pixel aperture ratio rather than reducing the voltage signal, which ensures that the voltage signal is within the set limits of the integrated chip, thereby improving the display effect of the display panel.

[0050] In some alternative embodiments, such as Figure 8 and Figure 9 As shown, the display panel also includes a plurality of pixel circuits 50 arranged along the first direction X and the second direction Y, wherein the plurality of pixel circuits 50 corresponding to the same repeating unit 10 are arranged along the first direction X.

[0051] Optionally, the sub-pixel 30 includes a pixel electrode 301, a light-emitting structure 302, and a common electrode 303. The pixel electrode 301 and the common electrode 303 are used to drive the light-emitting structure 302 to emit light. The pixel electrode 301 is electrically connected to the pixel circuit 50. Optionally, the display panel includes a pixel definition layer 60, which includes a pixel defining portion 61 and a pixel opening 62. The light-emitting structure 302 is located within the pixel opening 62. A portion of the common electrode 303 is located on the side of the pixel defining portion 61 facing away from the pixel electrode 301, and a portion of the pixel electrode 301 is located on the side of the pixel defining portion 61 facing the pixel circuit 50.

[0052] like Figure 8 As shown, pixel circuit 50 is located on the third Z-direction side of sub-pixel 30. However, to more clearly illustrate the relative positional relationship between pixel circuit 50 and repeating unit 10, in Figure 9 The pixel circuit 50 is positioned on one side of the sub-pixel 30 in the second direction Y. Figure 9 The relative positions of different circuits within pixel circuit 50 and the relative positions of different sub-pixels 30 are only shown.

[0053] Optional, such as Figure 7As shown, the display panel may also include a data signal line Data and a scan signal line Scan. The data signal line Data is used to connect the pixel circuit 50 of a plurality of sub-pixels 30 distributed along the second direction Y, and the scan signal line Scan is used to connect the pixel circuit 50 of a plurality of sub-pixels 30 distributed along the first direction X.

[0054] Pixel circuits 50 are used to drive sub-pixels 30 to emit light. Multiple pixel circuits 50 corresponding to the same repeating unit 10 refer to multiple pixel circuits 50 used to drive the sub-pixels 30 within that repeating unit 10 to emit light. Sub-pixels 30 and pixel circuits 50 are arranged in a one-to-one correspondence. Taking a repeating unit 10 that includes two first pixel groups 11 and one second pixel group 12, where the first pixel group 11 includes two display units 20 and the second pixel group 12 includes one display unit 20 as an example, the repeating unit 10 includes 15 sub-pixels 30, and each sub-pixel 30 corresponds to one of the 15 pixel circuits 50. The 15 pixel circuits 50 corresponding to the repeating unit 10 are arranged side by side along the first direction X.

[0055] In these optional embodiments, as described above, the sub-pixels 30 within the same repeating unit 10 are distributed in two rows and multiple columns, while the multiple pixel circuits 50 corresponding to the same repeating unit 10 are distributed in a single row along the first direction X. Regardless of which row of sub-pixels 30 the pixel circuit 50 corresponds to, it can be ensured that the distance between the interconnected pixel circuits 50 and the sub-pixels 30 is relatively close. The pixel circuit 50 can be a 2T1C circuit, where 2T1C refers to 2 transistors and 1 storage capacitor. Alternatively, the pixel circuit 50 can be a 7T1C, 8T2C, or similar circuit.

[0056] In some alternative embodiments, such as Figures 7 to 9 As shown, in the multiple pixel circuits 50 corresponding to the repeating unit 10, the spacing between any two adjacent units is the same; and / or, the projected areas of any two units along the third direction Z are the same, and the third direction Z is perpendicular to the plane containing the second direction Y and the first direction X.

[0057] In these optional embodiments, when the spacing between any two adjacent pixel circuits 50 corresponding to the repeating unit 10 is the same, the pixel circuits 50 corresponding to the repeating unit 10 are distributed more evenly, and the distance between each pixel circuit 50 and the sub-pixel 30 is close. When the projected area of ​​any two along the third direction Z is the same, the distribution area of ​​the multiple pixel circuits 50 is close, and the multiple pixel circuits 50 can be fabricated using the same wiring structure, which simplifies the film layer structure of the display panel and facilitates the fabrication of the display panel.

[0058] Optionally, the extension dimension of the same pixel circuit 50 in the second direction Y can be greater than its extension dimension in the first direction X. The smaller extension dimension of the pixel circuit 50 in the first direction X makes the total length of the multiple pixel circuits 50 in the first direction X and the total length of the two first pixel groups 11 and one second pixel group 12 in the first direction X in the repeating unit 10 close when the multiple pixel circuits 50 are arranged side by side in the first direction X, which facilitates the close arrangement of the pixel circuits 50 and the sub-pixels 30.

[0059] Optionally, the total length of the multiple pixel circuits 50 corresponding to the same repeating unit 10 in the first direction X is equal to the total length of the two first pixel groups 11 and one second pixel group 12 within the repeating unit 10 in the first direction X. Optionally, the length of the pixel circuit 50 in the second direction Y is the same as the length of the first pixel group 11 and the second pixel group 12 in the second direction Y. The distribution area and shape of the multiple pixel circuits 50 corresponding to the same repeating unit 10 are similar to the distribution area and shape of the two first pixel groups 11 and one second pixel group 12 within the repeating unit 10, which facilitates the close arrangement of the pixel circuits 50 and the sub-pixels 30.

[0060] In some optional embodiments, the projected area of ​​the plurality of pixel circuits 50 corresponding to the first pixel group 11 along the third direction Z is greater than the area of ​​the first pixel group 11, and the projected area of ​​the plurality of pixel circuits 50 corresponding to the second pixel group 12 along the third direction Z is smaller than the area of ​​the second pixel group 12, wherein the third direction Z is perpendicular to the plane containing the second direction Y and the first direction X.

[0061] The multiple pixel circuits 50 corresponding to the first pixel group 11 refer to pixel circuits 50 used to drive multiple sub-pixels 30 within the first pixel group 11 to emit light. Similarly, the multiple pixel circuits 50 corresponding to the second pixel group 12 refer to pixel circuits 50 used to drive multiple sub-pixels 30 within the second pixel group 12 to emit light.

[0062] In these optional embodiments, the distribution density of sub-pixels 30 in the first pixel group 11 is relatively high, and the number of pixel circuits 50 corresponding to the first pixel group 11 is relatively large. The distribution density of sub-pixels 30 in the second pixel group 12 is relatively low, and the number of pixel circuits 50 corresponding to the second pixel group 12 is relatively small. The projected area of ​​the multiple pixel circuits 50 corresponding to the first pixel group 11 is larger than the area of ​​the first pixel group 11, and some pixel circuits 50 can be located outside the area where the first pixel group 11 is located. The projected area of ​​the multiple pixel circuits 50 corresponding to the second pixel group 12 is smaller than the second pixel group 12, which can make room for some pixel circuits 50 used to drive the sub-pixels 30 in the first pixel group 11, and also make the distribution area of ​​each pixel circuit 50 corresponding to the first pixel group 11 and the distribution area of ​​each pixel circuit 50 corresponding to the second pixel group 12 close.

[0063] Optionally, the pixel circuit 50 corresponding to the first pixel group 11 and the pixel circuit 50 corresponding to the second pixel group 12 have the same projected area along the third direction Z. This makes the sizes of the multiple pixel circuits 50 closer and the parameters of each pixel circuit 50 more similar, thereby improving the uniformity of the display panel.

[0064] In some other alternative embodiments, such as Figure 10a As shown, the projected area of ​​the pixel circuit 50 corresponding to the first pixel group 11 along the third direction Z is smaller than the projected area of ​​the pixel circuit 50 corresponding to the second pixel group 12 along the third direction Z. For example, the first width H1 of the pixel circuit 50 corresponding to the first pixel group 11 in the first direction X is smaller than the second width H2 of the pixel circuit 50 corresponding to the second pixel group 12 in the first direction X. The smaller distribution area of ​​the pixel circuit 50 corresponding to the first pixel group 11 allows for more pixel circuits 50 to be placed in the area where the first pixel group 11 is located, thereby reducing the distance between the sub-pixels 30 and the pixel circuits 50 within the first pixel group 11. Figure 10a As shown, the distribution area of ​​the first pixel group 11 is the same as the distribution area of ​​the pixel circuit 50 corresponding to the first pixel group 11, and the distribution area of ​​the second pixel group 12 is the same as the distribution area of ​​the pixel circuit 50 corresponding to the second pixel group 12. In some optional embodiments, there is a first distance between the pixel circuit 50 corresponding to the first pixel group 11 and its connected sub-pixels 30, a second distance between the pixel circuit 50 corresponding to the first pixel group 11 and the sub-pixels 30 in the second pixel group 12, the first distance being less than the second distance, and / or, there is a third distance between the pixel circuit 50 corresponding to the second pixel group 12 and its connected sub-pixels 30, and a fourth distance between the pixel circuit 50 corresponding to the second pixel group 12 and the sub-pixels 30 in the first pixel group 11, the third distance being less than the fourth distance.

[0065] In these alternative embodiments, the distance between the interconnected sub-pixels 30 and pixel circuits 50 is small, which allows the connection lines between the sub-pixels 30 and their connected pixel circuits 50 to be set shorter, thereby simplifying the wiring structure of the display panel.

[0066] Optionally, the pixel circuit 50 includes a driving transistor. The pixel electrode 301 of the sub-pixel 30 and the source or drain of the driving transistor are electrically connected to each other. An example is given where the pixel electrode 301 and the source of the driving transistor are electrically connected. Figure 8 As shown, the pixel electrode 301 and the source of the driving transistor are located in different film layers, and the pixel electrode 301 and the driving transistor are spaced apart in the third direction Z. Also, please refer to... Figure 9When the pixel circuit 50 is located on the side of the sub-pixel 30 in the third direction Z, the sub-pixel 30 and the source of the driving transistor are spaced apart in the reference plane. The reference plane is perpendicular to the third direction Z and parallel to the first direction X and the second direction Y. Therefore, the distance between the pixel electrode 301 and the driving transistor includes a first interval along the third direction and a second interval in the reference plane. However, since the first interval of the pixel electrode 301 and the source of the driving transistor in the third direction is the same for multiple sub-pixels 30, the aforementioned first distance, second distance, third distance, and fourth distance can be considered as the distance between the corresponding pixel circuit 50 and the sub-pixel 30 on the reference plane, that is, the distance between the pixel electrode 301 of the sub-pixel 30 and the source of the driving transistor on the reference plane.

[0067] The first distance is less than the second distance, that is, the distance between the interconnected pixel electrode 301 and the source of the driving transistor on the reference plane is less than the distance between the pixel electrode 301 and the source of the other driving transistor on the reference plane. By connecting the pixel electrode 301 and the source of the driving transistor that are closer together, the extension length of the connecting line between the interconnected pixel electrode 301 and the source of the driving transistor on the reference plane can be reduced, simplifying the wiring structure of the display panel.

[0068] Optionally, the plurality of pixel circuits 50 include a first pixel circuit 51, a second pixel circuit 52 and a third pixel circuit 53. The first pixel circuit 51 is used to drive the first sub-pixel 31 to emit light, the second pixel circuit 52 is used to drive the second sub-pixel 32 to emit light, and the third pixel circuit 53 is used to drive the third sub-pixel 33 to emit light.

[0069] In some alternative embodiments, such as Figure 9 As shown, in the first pixel group 11, two third sub-pixels 33 are arranged along the second direction Y. Among the multiple pixel circuits 50 corresponding to the first pixel group 11, two third pixel circuits 53 are adjacent. This reduces the distance between the interconnected third sub-pixels 33 and the third pixel circuits 53, facilitating wiring.

[0070] There are various ways to arrange the first pixel circuit 51, the second pixel circuit 52, and the third pixel circuit 53. For example, according to Figure 9As shown, when the multiple sub-pixels 30 of the repeating unit 10 are arranged in two rows and multiple columns, the pixel circuits 50 corresponding to each sub-pixel 30 are arranged in a top-to-bottom and left-to-right order. For example, in the repeating unit 10, the first pixel column 40 contains the first sub-pixel 31 and the second sub-pixel 32 in sequence, and the second pixel column 40 contains two third sub-pixels 33. In the multiple pixel circuits 50, the first pixel circuit 51, the second pixel circuit 52, the third pixel circuit 53, and the third pixel circuit 53 are arranged side by side along the first direction X in a top-to-bottom and left-to-right order. On the one hand, this can reduce the distance between the interconnected sub-pixels 30 and the pixel circuits 50, thereby reducing the length of the connecting lines used to connect the sub-pixels 30 and the pixel circuits 50; on the other hand, it allows the connecting lines to be arranged sequentially, and the connecting lines are less likely to cross and short-circuit.

[0071] Alternatively, in some other optional embodiments, when the multiple sub-pixels 30 of the repeating unit 10 are arranged in two rows and multiple columns, two sub-pixels 30 are arranged along the second direction Y to form a pixel column 40, and the multiple pixel columns 40 are distributed along the first direction X. The multiple pixel circuits 50 corresponding to each pixel column 40 can be arranged sequentially from left to right. The arrangement order of the two pixel circuits 50 corresponding to the same pixel column 40 can be multiple, for example, as... Figure 9 As shown, the pixel circuits 50 corresponding to each sub-pixel 30 are arranged in the same pixel column 40 in a top-to-bottom order, or, as... Figure 10 As shown, the pixel circuits 50 corresponding to each sub-pixel 30 are arranged in a bottom-to-top order, or, as... Figure 11 As shown, in two adjacent pixel columns 40, one column arranges the pixel circuits 50 corresponding to each sub-pixel 30 in a top-to-bottom order, while the other column arranges the pixel circuits 50 corresponding to each sub-pixel 30 in a bottom-to-top order.

[0072] For example, such as Figure 11 As shown, in the repeating unit 10, the first sub-pixel 31 and the second sub-pixel 32 in the first pixel column 40 are arranged from top to bottom; the third sub-pixel 33 and the first sub-pixel 31 in the second pixel column 40 are arranged from top to bottom; and the second sub-pixel 32 and the third sub-pixel 33 in the third pixel column 40 are arranged from top to bottom. Figure 12 As shown, the multiple pixel circuits 50 corresponding to the first three pixel columns 40 of the repeating unit 10 can be arranged in the order of first pixel circuit 51, second pixel circuit 52, third pixel circuit 53, and so on. Alternatively, as... Figure 13As shown, the pixel circuits 50 corresponding to the first three pixel columns 40 of the repeating unit 10 can be arranged in the order of second pixel circuit 52, first pixel circuit 51, third pixel circuit 53, and second pixel circuit 52. Alternatively, the pixel circuits 50 corresponding to the first three pixel columns 40 of the repeating unit 10 can be arranged in the order of first pixel circuit 51, second pixel circuit 52, third pixel circuit 53, and second pixel circuit 52 and third pixel circuit 53. In other embodiments, such as... Figure 12 The pixel circuit 50 corresponding to the third sub-pixel 33 in the second column shown can even be set to the left of the pixel circuit 50 corresponding to the second sub-pixel 32 in the first column, as long as the connecting lines do not easily intersect.

[0073] Please continue reading to section 2. Figure 13 As shown, when the second pixel group 12 includes the aforementioned third pixel column 43 and fourth pixel column 44, the number of sub-pixels 30 included in the fourth pixel column 44 is less than the number of sub-pixels 30 included in the first pixel column 41, second pixel column 42, and third pixel column 43. Optionally, the third sub-pixel 33 of the fourth pixel column 44 is a make-up sub-pixel 34, that is, the third sub-pixel 33 in the second pixel group is a make-up sub-pixel 34. When multiple repeating units 10 are arrayed along the first direction X and the second direction Y, the gap between two adjacent make-up sub-pixels 34 along the second direction Y is relatively large.

[0074] Optionally, the display panel may also include a photosensitive area PA, which may be located between two adjacent vacant sub-pixels 34 along the second direction Y. Figure 2 The location of the photosensitive area PA is indicated by a dotted line. For example, a photosensitive device can be placed inside the display panel or on the backlight side of the display panel. The photosensitive device can obtain light information through the photosensitive area PA. Since the gap between two adjacent third sub-pixels 33 along the second direction Y in the fourth pixel column 44 is relatively large, the distribution area of ​​the photosensitive area PA can be set to be larger, thereby increasing the amount of light sensed by the photosensitive device and thus improving the light sensing accuracy.

[0075] Optionally, the photosensitive device may include a fingerprint reader, a photosensitive camera, etc.

[0076] Optionally, the metal traces within the pixel circuit 50 and the photosensitive area PA are staggered. For example, when the metal traces located on both sides of the photosensitive area PA are connected to each other, the metal traces can be arranged around the photosensitive area PA to improve the problem of the metal traces blocking light in the photosensitive area PA.

[0077] Optionally, when the sub-pixel 30 includes the aforementioned common electrode 303, and the common electrode 303 is a surface electrode, a photosensitive hole can be formed on the common electrode 303. The photosensitive hole is located within the photosensitive area PA to improve the occlusion of photosensitive information by the common electrode 303.

[0078] An embodiment of the third aspect of this application also provides a display device, which includes the display panel of any of the second aspect embodiments described above. Since the display device provided in the third aspect embodiment includes the display panel of any of the second aspect embodiments described above, it has the beneficial effects of the display panel of any of the second aspect embodiments described above, which will not be elaborated further here.

[0079] Optionally, the display device also includes a photosensitive device. When the display panel includes the aforementioned photosensitive area PA, the photosensitive device is configured to acquire photosensitive information through the photosensitive area. Since the aforementioned photosensitive area PA is located between two adjacent vacant sub-pixels 34 along the second direction Y, the area of ​​the photosensitive area PA can be large, thereby increasing the amount of photosensitive information acquired by the photosensitive device and improving the photosensitive accuracy of the photosensitive device.

[0080] The display devices in this application include, but are not limited to, mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, control consoles, and other devices with display functions.

[0081] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
