Excellent quality includes high contrast, high clarity, wide viewing angle, etc.; economic advantages include low power consumption, low cost of use, low production cost, etc.; practical advantages include flexibility, foldability, moderate size, ability to display multiple information formats, etc., and applicability to harsh environments.

[0003] TFT-LCD (Thin Film Transistor Liquid Crystal Display) has the advantages of low voltage, low power consumption, large amount of displayed information, and easy colorization. The display screen in TFT-LCD includes an array substrate and a color filter substrate formed by a pair of boxes, and a liquid crystal layer filling the gap between the array substrate and the color filter substrate.

[0043] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Unless otherwise defined, the technical terms or scientific terms used in this disclosure should be understood by people with ordinary skills in the field to which the present invention belongs. "First", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] 8K resolution is an experimental digital video standard with a resolution of 7680×4320 pixels. K stands for kilo, which means the number of pixels in the horizontal direction is several thousand. The pixels displayed by 8K resolution display devices are four times the pixels displayed by 4K resolution display devices. The resolution of the current mainstream high-definition TV (HDTV) is 1920×1080, which means that the resolution of 8K resolution display is 16 times larger than that of the current mainstream HDTV.

[0046] In the current 8K display devices, due to the high resolution (PPI) and small pixels of the 8K display devices, the overall aperture ratio of the 8K display devices is low, resulting in low transmittance. The display panel includes a pixel unit, each pixel unit includes a plurality of pixel structures, and each pixel structure includes a pixel electrode.

[0047] For example, Figure 1 is a schematic diagram of the structure of a pixel unit, such as Figure 1 As shown, the pixel unit includes 6 sub-pixels, the direction along which sub-pixel 1 to sub-pixel 4 are arranged is the first direction, and the direction along which sub-pixel 1 to sub-pixel 2 are arranged is the second direction. The sub-pixels in the same column, i.e., arranged parallel to the first direction, have the same color. For example, the two sub-pixels in the first column (sub-pixel 1 and sub-pixel 4) are red sub-pixels, the sub-pixels in the second column (sub-pixel 2 and sub-pixel 5) are green sub-pixels, and the sub-pixels in the third column (sub-pixel 3 and sub-pixel 6) are blue sub-pixels. Each sub-pixel includes a pixel electrode, and the structure of each pixel electrode is the same, which is a "horse" structure. The main body of the "horse" structure pixel electrode is a bent strip electrode, and connecting electrodes are respectively arranged on both sides of the main body. One end of the connecting electrode is connected to the main body, and the other end of the connecting electrode is away from the main body. Each connecting electrode is parallel to each other and has an inclination angle relative to the main body. The outer contour of the "horse" pixel electrode is a parallelogram. Replacing the pixel electrode of the straight strip structure in the current display panel with a pixel electrode of the "horse" structure can increase the transmittance of the display panel by more than 10%. However, due to the following Figure 1 As shown, the structure of each pixel electrode is the same in the row direction (second direction) and the column direction (first direction), and because the horse-shaped pixel structure is asymmetric, the inclination directions of the connecting electrodes are parallel, which will cause certain viewing angle problems.

[0048] In addition, when designing 8K display devices, the aperture ratios of two adjacent rows of sub-pixels are usually inconsistent, because the design of thin-film transistors (TFT), isolation columns (PS), via structures, and pixel capacitors must be considered comprehensively. Figure 2 This is a schematic diagram of the structure of a common 8K product pixel unit. Figure 2 As shown, the pixel unit includes 6 sub-pixels, the direction along which sub-pixels 1 to 4 are arranged is the first direction, the direction along which sub-pixels 1 to 2 are arranged is the second direction, and the sub-pixels in the same column (arranged parallel to the first direction) have the same color. Since the common electrodes in different rows need to be electrically connected through the common electrode line, a via structure needs to be provided. For example, Figure 2As shown, a first via structure 10 is provided in sub-pixel 2, and a second via structure 10' is provided in sub-pixel 5. However, the position of the first via structure 10 in sub-pixel 2 is different from the position of the second via structure 10' in sub-pixel 5. The first via structure 10 is located at the upper right corner of sub-pixel 2 and affects the arrangement of the pixel electrode structure in sub-pixel 2. The second via structure 10' is located at the lower right corner of sub-pixel 5 and does not affect the arrangement of the pixel electrode structure in sub-pixel 5, so that the aperture ratio of sub-pixel 2 (for example, a blue sub-pixel) is smaller than the aperture ratio of sub-pixel 5 (for example, a blue sub-pixel), thereby causing horizontal stripe Mura defects in low grayscale pure blue images. For example, Figure 3 This is the image when horizontal mura appears.

[0049] At least one embodiment of the present disclosure provides a pixel unit, which includes: a 2×2 sub-pixel area matrix, wherein the 2×2 sub-pixel area matrix includes a first sub-pixel area, a second sub-pixel area, a third sub-pixel area and a fourth sub-pixel area arranged in sequence in a clockwise direction, each sub-pixel area includes sub-pixels, a direction from a sub-pixel in the first sub-pixel area to a sub-pixel in the fourth sub-pixel area is a first direction, a direction from a sub-pixel in the first sub-pixel area to a sub-pixel in the second sub-pixel area is a second direction, and in a direction parallel to the first direction, adjacent sub-pixels have the same color; each sub-pixel includes a pixel electrode; a pixel electrode in the first sub-pixel area corresponds to a pixel electrode in the third sub-pixel area one-to-one, and a pixel electrode in the first sub-pixel area has the same structure as a pixel electrode corresponding thereto in the third sub-pixel area; a pixel electrode in the second sub-pixel area corresponds to a pixel electrode in the fourth sub-pixel area one-to-one, and a pixel electrode in the second sub-pixel area has the same structure as a pixel electrode corresponding thereto in the fourth sub-pixel area; a pixel electrode in the first sub-pixel area has a different structure from a pixel electrode in the fourth sub-pixel area that is adjacent to the pixel electrode along the first direction. The pixel unit can improve the horizontal Mura defect while ensuring high pixel transmittance.

[0050] It should be noted that one-to-one correspondence means that the number of pixel electrodes in the first sub-pixel area and the number of pixel electrodes in the third sub-pixel area are equal, and the arrangement of the sub-pixels and the colors of the corresponding sub-pixels are the same; the number of pixel electrodes in the second sub-pixel area and the number of pixel electrodes in the fourth sub-pixel area are equal, and the arrangement of the sub-pixels and the colors of the corresponding sub-pixels are the same.

[0051] For example, Figure 4 A schematic diagram of a planar structure of a pixel unit provided in one embodiment of the present disclosure is shown in FIG. Figure 4As shown, the pixel unit A1 includes a 2×2 sub-pixel area matrix, and the 2×2 sub-pixel area matrix includes a first sub-pixel area L1, a second sub-pixel area L2, a third sub-pixel area L3 and a fourth sub-pixel area L4 arranged in a clockwise direction, and the direction from the sub-pixels in the first sub-pixel area L1 to the sub-pixels in the fourth sub-pixel area L4 is a first direction A-A', and the direction from the sub-pixels in the first sub-pixel area L1 to the sub-pixels in the second sub-pixel area L2 is a second direction B-B', and each sub-pixel area includes a sub-pixel P.

[0052] For example, Figure 4 As shown, the first sub-pixel region L1 includes the first sub-pixel P1, the second sub-pixel P2 and the third sub-pixel P3, the second sub-pixel region L2 includes the fourth sub-pixel P4, the fifth sub-pixel P5 and the sixth sub-pixel P6, the third sub-pixel region L3 includes the seventh sub-pixel P7, the eighth sub-pixel P8 and the ninth sub-pixel P9, and the fourth sub-pixel region L4 includes the tenth sub-pixel P10, the eleventh sub-pixel P11 and the twelfth sub-pixel P12. Along the first direction AA', the colors of adjacent sub-pixels P are the same, for example, the first sub-pixel P1 and the twelfth sub-pixel P12 have the same color, the second sub-pixel P2 and the eleventh sub-pixel P11 have the same color, the third sub-pixel P3 and the tenth sub-pixel P10 have the same color, the fourth sub-pixel P4 and the ninth sub-pixel P9 have the same color, the fifth sub-pixel P5 and the eighth sub-pixel P8 have the same color, and the sixth sub-pixel P6 and the seventh sub-pixel P7 have the same color.

[0053] For example, each sub-pixel P includes a pixel electrode E, and the pixel electrode E1 in the first sub-pixel region L1 corresponds to the pixel electrode E3 in the third sub-pixel region L3, and the pixel electrode E1 in the first sub-pixel region L1 and the corresponding pixel electrode E3 in the third sub-pixel region L3 have the same structure. For example, the first sub-pixel P1 in the first sub-pixel region L1 and the ninth sub-pixel P9 in the third sub-pixel region L3 have the same color, and the pixel electrode E11 in the first sub-pixel region L1 and the pixel electrode E31 in the third sub-pixel region L3 have the same structure; the second sub-pixel P2 in the first sub-pixel region L1 and the eighth sub-pixel P8 in the third sub-pixel region L3 have the same color, and the pixel electrode E12 in the first sub-pixel region L1 and the pixel electrode E32 in the third sub-pixel region L3 have the same structure; the third sub-pixel P3 in the first sub-pixel region L1 and the seventh sub-pixel P7 in the third sub-pixel region L3 have the same color, and the pixel electrode E13 in the first sub-pixel region L1 and the pixel electrode E33 in the third sub-pixel region L3 have the same structure.

[0054] For example, the pixel electrode E2 in the second sub-pixel area L2 and the pixel electrode E4 in the fourth sub-pixel area L4 correspond one to one, and the pixel electrode E2 in the second sub-pixel area L2 and the corresponding pixel electrode E4 in the fourth sub-pixel area L4 have the same structure. For example, the fourth sub-pixel P4 in the second sub-pixel area L2 and the twelfth sub-pixel P12 in the fourth sub-pixel area L4 have the same color, and the pixel electrode E21 in the second sub-pixel area L2 and the pixel electrode E41 in the fourth sub-pixel area L4 have the same structure; the fifth sub-pixel P5 in the second sub-pixel area L2 and the eleventh sub-pixel P11 in the fourth sub-pixel area L4 have the same color, and the pixel electrode E22 in the second sub-pixel area L2 and the pixel electrode E42 in the fourth sub-pixel area L4 have the same structure; the sixth sub-pixel P6 in the second sub-pixel area L2 and the tenth sub-pixel P10 in the fourth sub-pixel area L4 have the same color, and the pixel electrode E23 in the second sub-pixel area L2 and the pixel electrode E43 in the fourth sub-pixel area L4 have the same structure.

[0055] For example, the structure of a pixel electrode E1 in the first sub-pixel region L1 is different from the structure of a pixel electrode E4 adjacent to the pixel electrode E1 along the first direction A-A' in the fourth sub-pixel region L4. For example, the structures of the pixel electrode E11 and the pixel electrode E41 may be different; or the structures of the pixel electrode E12 and the pixel electrode E42 may be different; or the structures of the pixel electrode E13 and the pixel electrode E43 may be different; or the structures of the pixel electrode E11 and the pixel electrode E41 may be different, and the structures of the pixel electrode E12 and the pixel electrode E42 may be different; or the structures of the pixel electrode E11 and the pixel electrode E41 may be different, and the structures of the pixel electrode E13 and the pixel electrode E43 may be different; or the structures of the pixel electrode E12 and the pixel electrode E42 may be different, and the structures of the pixel electrode E13 and the pixel electrode E43 may be different; or the structures of the pixel electrode E11 and the pixel electrode E41 may be different, and the structures of the pixel electrode E12 and the pixel electrode E42 may be different, and the structures of the pixel electrode E13 and the pixel electrode E43 may be different.

[0056] For example, the structure of a pixel electrode E2 in the second sub-pixel region L2 is different from the structure of a pixel electrode E3 adjacent to the pixel electrode E2 along the first direction A-A' in the third sub-pixel region L3. For example, the structures of the pixel electrode E21 and the pixel electrode E31 may be different; or the structures of the pixel electrode E22 and the pixel electrode E32 may be different; or the structures of the pixel electrode E23 and the pixel electrode E33 may be different; or the structures of the pixel electrode E21 and the pixel electrode E31 may be different, and the structures of the pixel electrode E22 and the pixel electrode E32 may be different; or the structures of the pixel electrode E21 and the pixel electrode E31 may be different, and the structures of the pixel electrode E23 and the pixel electrode E33 may be different; or the structures of the pixel electrode E22 and the pixel electrode E32 may be different, and the structures of the pixel electrode E23 and the pixel electrode E33 may be different; or the structures of the pixel electrode E21 and the pixel electrode E31 may be different, and the structures of the pixel electrode E22 and the pixel electrode E32 may be different, and the structures of the pixel electrode E23 and the pixel electrode E33 may be different.

[0057] For example, Figure 5 for Figure 4 Schematic diagram of the enlarged structure of a pixel electrode in FIG. Figure 5 Taking the pixel electrode E11 as an example, the pixel electrode includes a first electrode E111 and a plurality of second electrodes E112 . Each second electrode E112 is connected to the first electrode E111 , and the second electrodes E112 are arranged along an extension direction C of the first electrode E111 . Figure 6 for Figure 4 Schematic diagram of the enlarged structure of another pixel electrode in FIG. Figure 6 Taking the pixel electrode E12 as an example, the pixel electrode includes a first electrode E121 and a plurality of second electrodes E122 . Each second electrode E122 is connected to the first electrode E121 , and the second electrodes E122 are arranged along an extension direction C of the first electrode E121 .

[0058] For example, the first electrode is in a zigzag shape, and the first electrode includes: a first sub-electrode, a second sub-electrode and a third sub-electrode, one end of the first sub-electrode is connected to one end of the second sub-electrode, the other end of the second sub-electrode is connected to one end of the third sub-electrode, the first sub-electrode and the third sub-electrode are located on different sides of the second sub-electrode, and the end of each second electrode is connected to the first electrode. Figure 5As shown, the first electrode E111 is in a zigzag shape, for example, the structure of the first electrode E111 is a vertical "Z"-shaped structure, and the first electrode E111 includes: a first sub-electrode E111a, a second sub-electrode E111b and a third sub-electrode E111c, one end of the first sub-electrode E111a is connected to one end of the second sub-electrode E111b, and the other end of the second sub-electrode E111b is connected to one end of the third sub-electrode E111c, the first sub-electrode E111a and the third sub-electrode E111c are located on different sides of the second sub-electrode E111b, and one end of each second electrode E112 is connected to the first electrode E111, and each second electrode E112 extends in a direction away from the main body of the first electrode E111.

[0059] For example, multiple second electrodes E112 are arranged along the extension direction of the first electrode E111, which means that: multiple second electrodes E112 are all arranged along the extension direction of the first sub-electrode E111a, or are arranged along the extension direction of the third sub-electrode E111c; or, some of the second electrodes E112 are arranged along the extension direction of the first sub-electrode E111a, and some of the second electrodes E112 are arranged along the extension direction of the third sub-electrode E111c; or, some of the second electrodes E112 are arranged along the extension direction of the first sub-electrode E111a, some of the second electrodes E112 are arranged along the extension direction of the second sub-electrode E111b, and some of the second electrodes E112 are arranged along the extension direction of the third sub-electrode E111c. The embodiments of the present disclosure are not limited to this.

[0060] For example, since the second sub-electrode E111b intersects with the first sub-electrode E111a and the third sub-electrode E111c, the extension direction of the second sub-electrode E111b is not collinear with the extension direction of the first sub-electrode E111a and the extension direction of the third sub-electrode E111c. Since signal lines are arranged on both sides of the pixel electrode, for example, the signal lines are data lines, and the data lines are configured to transmit data signals to the pixel electrode, the extension direction of the second sub-electrode E111b is not collinear with the extension direction of the first sub-electrode E111a and the extension direction of the third sub-electrode E111c, which can avoid the first electrode E111 being closer to one of the signal lines located on both sides of the pixel electrode and farther from the other signal line, resulting in a larger coupling capacitance between the first electrode E111 and the closer signal line, and a smaller coupling capacitance between the first electrode E111 and the farther signal line, that is, resulting in a large difference in coupling capacitance between various regions of the display panel formed subsequently, thereby affecting the display effect of the display panel.

[0061] It should be noted that the different sides of the second sub-electrode E111b refer to the main body of the second sub-electrode E111b and the two sides of the straight line parallel to the extension direction of the second sub-electrode E111b, rather than the two sides of the end of the second sub-electrode E111b, and the first sub-electrode E111a and the third sub-electrode E111c are arranged on different sides of the second sub-electrode E111b, so that the second electrodes E112 connected to the first electrode E111 can be more evenly distributed on different sides of the second sub-electrode E111b. When the multiple second electrodes E112 are parallel to each other, for example, Figure 5 The extending direction of the second electrode is parallel to the first extending direction aa', and the pixel electrode has good symmetry, so that the transmittance uniformity of the display panel including the pixel electrode is higher.

[0062] For example, Figure 5 As shown, the plurality of second electrodes E112 include: a first type of second electrode E112a and a second type of second electrode E112b, wherein the first end E112a1 of the first type of second electrode E112a is connected to the first sub-electrode E111a, and the second end E112a2 of the first type of second electrode E112a is far away from the first sub-electrode E111a; the first end E112b1 of the second type of second electrode E112b is connected to the third sub-electrode E111c, and the second end E112b2 of the second type of second electrode E112b is far away from the third sub-electrode E111c, the first type of second electrode E112a and the second type of second electrode E112b are located on different sides of the second sub-electrode E111b, and the first type of second electrode E112a and the second type of second electrode E112b are parallel. For example, in some embodiments, the first type of second electrode E112a and the second type of second electrode E112b may also be non-parallel. For example, Figure 6 The second electrode shown in FIG. 1 also has a similar structure as described above, except that Figure 6 The extension directions of the first type of second electrodes E122a and the second type of second electrodes E122b are both parallel to the second extension direction bb′, which will not be described in detail herein.

[0063] It should be noted that other pixel electrodes also have designs similar to the above, which will not be described in detail here.

[0064] For example, Fig. 7A This is a schematic diagram of an enlarged structure of a first electrode provided in one embodiment of the present disclosure, such as Fig. 7AAs shown, in a first electrode E111, the first sub-electrode E111a is parallel or substantially parallel to the third sub-electrode E111c, so that the overall structure of the pixel electrode can be symmetrical, so that the display effect of the display panel including the pixel structure is better. Due to the limitation of process conditions, when the angle between the extension direction of the first sub-electrode and the extension direction of the third sub-electrode is in the range of 0 degrees to 10 degrees, it can also be considered that the first sub-electrode is substantially parallel to the third sub-electrode. For example, the first angle α between the second sub-electrode E111b and the first sub-electrode E111a is equal to or substantially equal to the second angle β between the second sub-electrode E111b and the third sub-electrode E111c.

[0065] For example, the angle α between the second sub-electrode E111b and the first sub-electrode E111a and the angle β between the second sub-electrode E111b and the third sub-electrode E111c can be both acute angles, both right angles, or both obtuse angles. When the angle α between the second sub-electrode E111b and the first sub-electrode E111a and the angle β between the second sub-electrode E111b and the third sub-electrode E111c are both obtuse angles, because the second electrode E112 is dispersed over a larger area, the transmittance of the display panel including the pixel electrode can be greater than the angle α between the second sub-electrode E111b and the first sub-electrode E111a and the angle β between the second sub-electrode E111b and the third sub-electrode E111c under the conditions of the same number of second electrodes E112 and the same length of the first electrode E111. There are cases where the angle β between E111b and the third sub-electrode E111c is a right angle and an acute angle; similarly, when the angle α between the second sub-electrode E111b and the first sub-electrode E111a and the angle β between the second sub-electrode E111b and the third sub-electrode E111c are both right angles, the transmittance of the display panel including the pixel electrode is greater than the case where the angle α between the second sub-electrode E111b and the first sub-electrode E111a and the angle β between the second sub-electrode and the third sub-electrode E111c are both acute angles.

[0066] For example, Figure 7B This is a schematic diagram of an enlarged structure of another first electrode provided in an embodiment of the present disclosure, such as Figure 7B As shown, a slit E111b is further provided in the second sub-electrode E111b, thereby increasing the aperture ratio of the pixel electrode. Figure 7C This is a schematic diagram of an enlarged structure of another first electrode provided in an embodiment of the present disclosure. Two slits E111b are provided in the second sub-electrode E111b, which can further increase the aperture ratio of the pixel electrode.

[0067] For example, combined with Figure 4 , Figure 5 and Figure 6In the first sub-pixel region L1, the pixel electrodes in the first sub-pixel P1 include a plurality of second electrodes E112 that extend in the same direction, all parallel to the first extension direction a-a'; the pixel electrodes in the second sub-pixel P2 include a plurality of second electrodes E122 that extend in the same direction, all parallel to the second extension direction bb'. Similarly, the pixel electrodes in the third sub-pixel region L3, the fifth sub-pixel P5, the seventh sub-pixel P7, the ninth sub-pixel P9, and the eleventh sub-pixel P11 include a plurality of second electrodes that extend in the same direction, all parallel to the first extension direction a-a'; the pixel electrodes in the fourth sub-pixel P4, the sixth sub-pixel P6, the eighth sub-pixel P8, the tenth sub-pixel P10, and the twelfth sub-pixel P12 include a plurality of second electrodes that extend in the same direction, all parallel to the second extension direction bb', and the first extension direction a-a' and the second extension direction bb' intersect each other. There are two included angles between the first extending direction a-a' and the second extending direction bb', one is an acute angle and the other is an obtuse angle, and the acute angle is greater than 0 degree and less than or equal to 90 degrees.

[0068] For example, Figure 4 As shown, the horizontally set x-axis and the vertically set y-axis are perpendicular to each other, the first direction A-A' is parallel to the y-axis, and the second direction BB' is parallel to the x-axis. Due to the need to set up via structures, isolation columns, etc., there will be slight structural differences in the pixel electrodes in at least the sub-pixels in the same column in the first sub-pixel area L1 and the fourth sub-pixel area L4. For example, there are slight structural differences between the pixel electrode E12 in the second sub-pixel P2 located in the middle position of the first sub-pixel area L1 and the pixel electrode E42 in the eleventh sub-pixel P11 located in the middle position of the fourth sub-pixel area L4, which results in the sum of the aperture ratios of the three sub-pixels in the first sub-pixel area L1 and the sum of the aperture ratios of the three sub-pixels in the fourth sub-pixel area L4 being different, but the slight structural differences can be ignored as a whole.

[0069] For example, in one example, ignoring minor differences in structure, the pixel electrodes in two adjacent columns of sub-pixels are axially symmetrical. For example, in the first sub-pixel area L1, the pixel electrode E11 and the pixel electrode E12 in the first sub-pixel P1 are axially symmetrical about the y-axis, and the pixel electrode E12 and the pixel electrode E13 in the first sub-pixel P1 are axially symmetrical about the y-axis. Between the first sub-pixel area L1 and the second sub-pixel area L2, the pixel electrode E13 in the third sub-pixel P3 in the first sub-pixel area L1 and the pixel electrode E21 in the fourth sub-pixel P4 in the second sub-pixel area L2 are axially symmetrical about the y-axis. There may also be related designs in other sub-pixel areas or between sub-pixel areas, which will not be repeated here.

[0070] For example, in one example, although Figure 4Not shown, the pixel electrodes in the sub-pixels located in the same column in the first sub-pixel area L1 and the fourth sub-pixel area L4 may be roughly axially symmetrical, for example, the pixel electrode in the first sub-pixel P1 in the first sub-pixel area L1 and the pixel electrode in the twelfth sub-pixel P12 in the fourth sub-pixel area L4 are axially symmetrical about the x-axis; the pixel electrode in the second sub-pixel P2 in the first sub-pixel area L1 and the pixel electrode in the eleventh sub-pixel P11 in the fourth sub-pixel area L4 are axially symmetrical about the x-axis; the pixel electrode in the third sub-pixel P3 in the first sub-pixel area L1 and the pixel electrode in the tenth sub-pixel P10 in the fourth sub-pixel area L4 are axially symmetrical about the x-axis. Similarly, the second sub-pixel area L2 and the third sub-pixel area L3 may also have a setting of related symmetrical structures.

[0071] For example, from Figure 4 It can be seen that in each sub-pixel in the first sub-pixel area L1, the second sub-pixel area L2, the third sub-pixel area L3 and the fourth sub-pixel area L4, the extension direction of the first electrode in each pixel electrode is parallel to the y-axis, the second electrode in each pixel electrode is inclined and forms a certain angle with the y-axis, and the entire sub-pixel is non-inclined and parallel to the y-axis. For example, Figure 5 The extension direction of the first electrode E111 in the middle pixel electrode E11 is parallel to the y-axis, and the extension direction of the second electrode E112 forms a certain angle with the y-axis.

[0072] For example, ignoring minor differences in structure, the length of each sub-pixel in the first sub-pixel area L1, the second sub-pixel area L2, the third sub-pixel area L3 and the fourth sub-pixel area L4 is equal or approximately equal, the width of each sub-pixel is also equal or approximately equal, and the length of the second electrode in each pixel electrode in each sub-pixel is also equal or approximately equal, and the length of the first electrode in each pixel electrode in each sub-pixel along the y-axis direction is also equal or approximately equal.

[0073] For example, in each sub-pixel in the first sub-pixel area L1, the second sub-pixel area L2, the third sub-pixel area L3 and the fourth sub-pixel area L4, the length of the first electrode in each pixel electrode is greater than the length of the second electrode connected to the first electrode, and the width of the first electrode is greater than the width of any second electrode connected to the first electrode. That is, a plurality of second electrodes with narrower widths and shorter lengths are connected by a first electrode with wider widths and longer lengths to achieve connectivity between the electrodes. The pixel electrode can effectively improve the transmittance of the subsequently formed display panel while ensuring a low risk of breakage.

[0074] For example, Figure 4As shown, the first sub-pixel area L1, the second sub-pixel area L2, the third sub-pixel area L3 and the fourth sub-pixel area L4 each include three sub-pixels of a 1×3 sub-pixel matrix, that is, the four sub-pixel areas each include three sub-pixels, that is, the first sub-pixel area L1, the second sub-pixel area L2, the third sub-pixel area L3 and the fourth sub-pixel area L4 each include a row of three columns of sub-pixels.

[0075] For example, three sub-pixels in the first sub-pixel region, the second sub-pixel region, the third sub-pixel region, and the fourth sub-pixel region are respectively a red sub-pixel (R), a green sub-pixel (G), and a blue sub-pixel (B).

[0076] For example, there are multiple arrangements of red sub-pixels (R), green sub-pixels (G), and blue sub-pixels (B), and the red sub-pixels (R), green sub-pixels (G), and blue sub-pixels (B) can be arranged in any combination; and the arrangement of RGB in the first sub-pixel area L1 and the fourth sub-pixel area L4 is the same, the arrangement of RGB in the second sub-pixel area L2 and the third sub-pixel area L3 is the same, and the arrangement of red sub-pixels (R), green sub-pixels (G), and blue sub-pixels (B) in the first sub-pixel area L1 and the fourth sub-pixel area L4 and the second sub-pixel area L2 and the third sub-pixel area L3 can be the same. For example, Figure 4 As shown, the arrangement of RGB in the first sub-pixel area L1 and the fourth sub-pixel area L4 is the same as the arrangement of RGB in the second sub-pixel area L2 and the third sub-pixel area L3, and they are all red sub-pixels (R), green sub-pixels (G) and blue sub-pixels (B) in sequence along the x-axis direction.

[0077] For example, in Figure 5 and Figure 6 In the embodiment, the first type of second electrode connected to the first sub-electrode and the second type of second electrode connected to the third sub-electrode are parallel and have equal lengths, which can ensure the symmetry of the overall structure of the pixel electrode, and further ensure the uniformity of the transmittance of the display panel including the pixel electrode.

[0078] For example, Figure 8 A schematic diagram of an enlarged structure of another pixel electrode provided in an embodiment of the present disclosure is shown in FIG. Figure 8 As shown, the extension direction of the first electrode E111 in each pixel electrode is parallel to the y-axis, the second electrode E112 in each pixel electrode is perpendicular to the y-axis, and the entire sub-pixel is non-inclined and also parallel to the y-axis.

[0079] For example, Fig. 9An enlarged structural schematic diagram of another pixel electrode provided for an embodiment of the present disclosure, wherein the extension direction of the first electrode E121 in each pixel electrode is parallel to the y-axis, the second electrode E122 in each pixel electrode is perpendicular to the y-axis, and the entire sub-pixel is non-inclined and also parallel to the y-axis.

[0080] For example, Figure 8 and Fig. 9 The schematic diagram of the planar structure of the pixel unit formed by the combination is as follows Fig.10 As shown, Fig.10 A schematic diagram of a planar structure of a pixel unit provided in yet another embodiment of the present disclosure, Fig.10 In the structure shown, compared to Figure 4 Except that the second electrode E112 in each pixel electrode is perpendicular to the y-axis, other related descriptions can be found in the above description of Figure 4 The relevant description will not be repeated here.

[0081] For example, Fig.11 A schematic diagram of an enlarged structure of another pixel electrode provided in an embodiment of the present disclosure is shown in FIG. Fig.11 As shown, the extension direction CC' of the first electrode E111 in each pixel electrode E11 is parallel to the y-axis, the second electrode E112 in each pixel electrode is non-perpendicular to the y-axis, and the entire sub-pixel is non-inclined and parallel to the y-axis.

[0082] For example, Fig.12 An enlarged structural schematic diagram of another pixel electrode provided for an embodiment of the present disclosure, wherein the extension direction of the first electrode E121 in each pixel electrode E12 is parallel to the y-axis, the second electrode E122 in each pixel electrode is non-perpendicular to the y-axis, and the entire sub-pixel is non-inclined and also parallel to the y-axis.

[0083] For example, Fig.11 and Fig.12 The schematic diagram of the planar structure of the pixel unit formed by the combination is as follows Fig.13 As shown, Fig.13 A schematic diagram of a planar structure of a pixel unit provided in yet another embodiment of the present disclosure, Fig.13 In the structure shown, compared to Figure 4 Except that the extension directions of the plurality of second electrodes E112 in each pixel electrode are not completely parallel, other related descriptions can be referred to the above Figure 4 The relevant description will not be repeated here.

[0084] For example, Figures 11 to 13As shown, in the first pixel area L1, there are a first sub-pixel P1 and a second sub-pixel P2 adjacent to each other in the second direction BB', the pixel electrode E11 in the first sub-pixel P1 is the first pixel electrode E11, and the pixel electrode E12 in the second sub-pixel P2 is the second pixel electrode E12. The extension direction of the first type of second electrode E112a in the second electrode E112 included in the first pixel electrode E11 intersects with the extension direction of the first type of second electrode E122a in the second electrode E122 included in the second pixel electrode E12, and the extension direction of the second type of second electrode E112b in the second electrode E112 included in the first pixel electrode E11 intersects with the extension direction of the second type of second electrode E122b in the second electrode E122 included in the second pixel electrode E12.

[0085] For example, Fig.14 A schematic diagram of a planar structure of another pixel unit provided in an embodiment of the present disclosure is shown. Fig.15 for Fig.14 The enlarged structural diagram of a pixel electrode in FIG. Fig.14 and Fig.15 The first type of second electrode E112a is not parallel to the second type of second electrode E112b, and the plurality of second electrodes E112 further include a third type of second electrode E112c, a first end E112c1 of the third type of second electrode E112c is connected to the second sub-electrode E111b, and a second end E112c2 of the third type of second electrode E112c is away from the second sub-electrode E111b.

[0086] For example, Fig.15 As shown, the third-type second electrode E112c is parallel to the first-type second electrode E112a, and the first-type second electrode E112a and the third-type second electrode E112c are located on the same side of the first sub-electrode E111a.

[0087] or, Fig.16 An embodiment of the present disclosure provides Fig.14 Another schematic diagram of the enlarged structure of a pixel electrode is shown in FIG. Fig.16 As shown, the third-type second electrode E122c is parallel to the first-type second electrode E122ab, and the first-type second electrode E122a and the third-type second electrode E122c are located on the same side of the second sub-electrode E121b.

[0088] For example, Fig.15 and Fig.16 The schematic diagram of the planar structure of the pixel unit formed by the combination is as follows Fig.14 As shown, combined Fig.14 , Fig.15 and Fig.16, in the first subpixel P1 and the second subpixel P2 adjacent in the first direction A-A', the first subpixel P1 includes a first pixel electrode E11, and the second subpixel P2 includes a second pixel electrode E12; an extension direction of a first type of second electrode E112a in the second electrode E112 included in the first pixel electrode E111 intersects with an extension direction of a first type of second electrode E122a in the second electrode E122 included in the second pixel electrode E12; an extension direction of a second type of second electrode E112b in the second electrode E112 included in the first pixel electrode E111 intersects with an extension direction of a second type of second electrode E122b in the second electrode E122 included in the second pixel electrode E12; an extension direction of a third type of second electrode E112c in the second electrode E112 included in the first pixel electrode E111 intersects with an extension direction of a third type of second electrode E122c in the second electrode E122 included in the second pixel electrode E12.

[0089] For example, in Fig.15 In the embodiment, the first type second electrode E112a is arranged along the extension direction of the first sub-electrode E111a, the third type second electrode E112c is arranged along the extension direction of the second sub-electrode E111b, and the second type second electrode E112b is arranged along the extension direction of the third sub-electrode E111c.

[0090] For example, in Fig.15 In the embodiment, the first vertical distances between the other ends of the plurality of first-type second electrodes E112a and the first sub-electrode E111a are all equal, the second vertical distances between the other ends of the plurality of second-type second electrodes E112b and the third sub-electrode E111c are all equal, and the first vertical distance is equal to the second vertical distance.

[0091] For example, in one example, Fig.15 In the embodiment, the first vertical distances between the other ends of the multiple first-type second electrodes E112a and the multiple third-type second electrodes E112c and the first sub-electrode E111a are equal, the second vertical distances between the other ends of the multiple second-type second electrodes E112b and the third sub-electrode E111c are equal, and the first vertical distance is equal to the second vertical distance.

[0092] Similarly, in Fig.16 There are also similar structures and positional relationships as mentioned above, which will not be repeated here.

[0093] For example, Fig.17 A schematic diagram of a planar structure of another pixel unit provided in an embodiment of the present disclosure is shown in FIG. Fig.17As shown, the four sub-pixel areas each include four sub-pixels constituting a 1×4 sub-pixel matrix, that is, the four sub-pixel areas each include four sub-pixels, and the four sub-pixel areas each include a 1×4 sub-pixel matrix, which means that the colors of the sub-pixels in the same column (column direction is a direction parallel to the first direction A-A') in the first sub-pixel area L1 and the fourth sub-pixel area L4 are the same, and the colors of the sub-pixels in the same column in the second sub-pixel area L2 and the third sub-pixel area L3 are the same. The four sub-pixels in the four sub-pixel areas are respectively a red sub-pixel (R), a green sub-pixel (G), a blue sub-pixel (B), and a white sub-pixel (W). There are many arrangements of R, G, B, and W, and R, G, B, and W can be arranged in any combination; and the arrangement of RGBW in the first sub-pixel area L1 and the fourth sub-pixel area L4 is the same, the arrangement of RGBW in the second sub-pixel area L2 and the third sub-pixel area L3 is the same, and the arrangement of RGBW in the first sub-pixel area L1 and the fourth sub-pixel area L4 and the second sub-pixel area L2 and the third sub-pixel area L3 can be the same; as shown Fig.17 As shown, the arrangement of RGBW in the first sub-pixel region L1 and the fourth sub-pixel region L4 is the same as that in the second sub-pixel region L2 and the third sub-pixel region L3, both of which are RGBW.

[0094] For example, the pixel unit A1 includes a first subpixel P1, a second subpixel P2, a third subpixel P3, a fourth subpixel P4, a fifth subpixel P5, a sixth subpixel P6, a seventh subpixel P7, an eighth subpixel P8, a ninth subpixel P9, a tenth subpixel P10, an eleventh subpixel P11, a twelfth subpixel P12, a thirteenth subpixel P13, a fourteenth subpixel P4, a fifteenth subpixel P15 and a sixteenth subpixel P16 arranged in a clockwise direction.

[0095] It should be noted that, in addition to the related structures described in the above embodiments, in the embodiments of the present disclosure, the pixel electrode included in each sub-pixel may also be inclined, and there is a certain angle between the extension direction of the first electrode and the y-axis, so that the entire sub-pixel is also inclined, and the inclination direction of the sub-pixel is the same as that of the pixel electrode, which will not be described in detail.

[0096] For example, Fig.18 for Figure 4 , Fig.10 , Fig.13 , Fig.14 and Fig.17 The pixel unit shown is used for displaying the screen image when the panel is normally displayed. Fig.18 As can be seen from the figure, there is no horizontal Mura.

[0097] At least one embodiment of the present disclosure further provides an array substrate, which includes a plurality of pixel units, gate lines, data lines, and thin film transistors disposed in each sub-pixel in any of the above embodiments, and the pixel units are arranged in an array.

[0098] For example, Fig.19 A schematic diagram of a planar structure of an array substrate provided in an embodiment of the present disclosure is shown in FIG. Fig.19 As shown, the array substrate includes: twelve thin film transistors, which are respectively arranged in each sub-pixel, that is, there is a thin film transistor in each sub-pixel, and each thin film transistor includes a source and a drain.

[0099] For example, the array substrate 100 further includes two gate lines and six data lines. Fig.19 As shown, the gate lines are arranged along the direction of the y-axis, and the data lines are arranged along the direction of the x-axis. The pixel units included in the array substrate include the first sub-pixel P1, the second sub-pixel P2, the third sub-pixel P3, the fourth sub-pixel P4, the fifth sub-pixel P5, the sixth sub-pixel P6, the seventh sub-pixel P7, the eighth sub-pixel P8, the ninth sub-pixel P9, the tenth sub-pixel P10, the eleventh sub-pixel P11 and the twelfth sub-pixel P12 arranged in clockwise order. The two gate lines are the first gate line G1 and the second gate line G2, and the six data lines are the first data line D1, the second data line D2, the third data line D3, the fourth data line D4, the fifth data line D5 and the sixth data line D6 arranged in sequence along the direction of the x-axis. The gate lines and the data lines are electrically connected to the thin film transistors respectively. The first gate line G1 is electrically connected to the first subpixel P1, the second subpixel P2, the third subpixel P3, the fourth subpixel P4, the fifth subpixel P5 and the sixth subpixel P6, and the second gate line G2 is electrically connected to the seventh subpixel P7, the eighth subpixel P8, the ninth subpixel P9, the tenth subpixel P10, the eleventh subpixel P11 and the twelfth subpixel P12.

[0100] For example, from Fig.19In the figure, it can be seen that the twelve thin film transistors T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, and T12 are respectively arranged in the first subpixel P1, the second subpixel P2, the third subpixel P3, the fourth subpixel P4, the fifth subpixel P5, the sixth subpixel P6, the seventh subpixel P7, the eighth subpixel P8, the ninth subpixel P9, the tenth subpixel P10, the eleventh subpixel P11, and the twelfth subpixel P12.

[0101] For example, Fig. 20 A schematic diagram of a planar structure of another array substrate provided in an embodiment of the present disclosure is shown as follows: Fig. 20 As shown, the array substrate includes: sixteen thin film transistors, which are respectively arranged in each sub-pixel, that is, there is a thin film transistor in each sub-pixel, and each thin film transistor includes a source and a drain.

[0102] For example, the array substrate 100 further includes two gate lines and eight data lines. Fig. 20 As shown, the gate lines are arranged along the direction of the y-axis, and the data lines are arranged along the direction of the x-axis. The array substrate includes two gate lines, namely the first gate line G1 and the second gate line G2. The array substrate includes eight data lines, namely the first data line D1, the second data line D2, the third data line D3, the fourth data line D4, the fifth data line D5, the sixth data line D6, the seventh data line D7, and the eighth data line D8, which are sequentially arranged along the direction of the x-axis. The gate lines and the data lines are electrically connected to the thin film transistors, respectively. The first gate line G1 is electrically connected to the first sub-pixel P1, the second sub-pixel P2, the third sub-pixel P3, the fourth sub-pixel P4, the fifth sub-pixel P5, the sixth sub-pixel P6, the seventh sub-pixel P7, and the eighth sub-pixel P8.

The same data line is electrically connected to the sub-pixels located in the same column, the first data line D1 is electrically connected to the first sub-pixel P1 and the sixteenth sub-pixel P16; the second data line D2 is electrically connected to the second sub-pixel P2 and the fifteenth sub-pixel P15, the third data line D3 is electrically connected to the third sub-pixel P3 and the fourteenth sub-pixel P14, the fourth data line D4 is electrically connected to the fourth sub-pixel P4 and the thirteenth sub-pixel P13, the fifth data line D5 is electrically connected to the fifth sub-pixel P5 and the twelfth sub-pixel P12, the sixth data line D6 is electrically connected to the sixth sub-pixel P6 and the eleventh sub-pixel P11, the seventh data line D7 is electrically connected to the seventh sub-pixel P7 and the tenth sub-pixel P10, and the eighth data line D8 is electrically connected to the eighth sub-pixel P8 and the ninth sub-pixel P9.

[0103] For example, at least one embodiment of the present disclosure provides a display panel. Fig.21 is a cross-sectional view of a display panel provided by an embodiment of the present disclosure, such as Fig.21 As shown, the display panel 200 includes: the array substrate 100 in any of the above embodiments, the counter substrate 300 and a liquid crystal layer 400 located between the array substrate 100 and the counter substrate 300. Fig.21 As can be seen from the figure, the array substrate 100 and the counter substrate 300 are arranged oppositely, the liquid crystal layer 400 and the sealing glue 500 are located between the array substrate 100 and the counter substrate 300, and the array substrate 100 includes a plurality of pixel units A1. For example, the counter substrate 300 may be a color filter substrate, and the counter substrate 300 may include a plurality of color resist units, and the color resist units correspond to the positions of the pixel units A1 on the array substrate. In the color resist unit, a black matrix 700 is arranged in the area outside the red color resist layer, the green color resist layer and the blue color resist layer, and a spacer 600 is arranged on the side of the black matrix 700 facing the array substrate 100, and the spacer 600 abuts against the array substrate 100 to form a space for accommodating the liquid crystal layer 400. Alignment films are also arranged on the array substrate 100 and the counter substrate 300, and the alignment films are aligned by friction.

[0104] For example, the liquid crystal molecules in the liquid crystal layer 400 may be negative liquid crystals, which can further improve the transmittance of the display panel, and negative liquid crystals do not have the risk of scratch uniformity. It should be noted that the liquid crystal molecules in the liquid crystal layer 400 may also be positive liquid crystals, which is not limited in the embodiments of the present disclosure.

[0105] For example, the display panel 200 may be a display panel in an advanced super dimensions switch (ADS) mode. The display panel in the ADS mode is suitable for large-size television (TV) fields due to its good viewing angle characteristics and high transmittance. Generally, the higher the pixel density (pixels per inch, PPI) of the display panel, the lower the transmittance. For the display panel in the ADS mode, the higher the PPI, the lower the transmittance. Therefore, the pixel unit provided by the embodiment of the present disclosure can effectively improve the transmittance of the display panel in the ADS mode with a larger resolution.

[0106] For example, the display device including the display panel can be a liquid crystal display device, electronic paper, an organic light-emitting diode (OLED) display device, an active-matrix organic light-emitting diode (AMOLED) display device, a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame or a navigator, or any other product or component with a display function.

[0107] For example, the pixel unit, array substrate, and display panel provided by the embodiments of the present disclosure can solve the problem of horizontal stripes and achieve a wide viewing angle to improve the display effect of the display panel.
