Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It should be apparent that the described embodiments are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Unless defined otherwise, technical or scientific terms used herein should have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in this disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item preceding the word comprises the element or item listed after the word and its equivalent, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
The 8K resolution is an experimental digital video standard, and the resolution is 7680 × 4320 pixels. K denotes thousands (kilo), i.e., the number of pixels in the horizontal direction is several thousands. The pixels displayed by the 8K resolution display device are four times of the pixels displayed by the 4K resolution display device, and the resolution of the current mainstream High Definition TV (HDTV) is 1920 × 1080, that is, the resolution of the 8K resolution display device is 16 times larger than that of the current mainstream High Definition TV.
In the current 8K display device, since the 8K display device has a high resolution (PPI) and a small pixel, the aperture ratio of the entire 8K display device is low, resulting in a low transmittance thereof. The display panel includes pixel units, each of which includes a plurality of pixel structures, each of which includes a pixel electrode.
For example, fig. 1 is a schematic structural diagram of a pixel unit, as shown in fig. 1, the pixel unit includes 6 sub-pixels, a direction along which the sub-pixels 1 to 4 are arranged is a first direction, a direction along which the sub-pixels 1 to 2 are arranged is a second direction, and the sub-pixels in the same column, that is, the sub-pixels arranged in parallel with the first direction have the same color. For example, two sub-pixels (sub-pixel 1 and sub-pixel 4) in the first column are red sub-pixels, two sub-pixels (sub-pixel 2 and sub-pixel 5) in the second column are green sub-pixels, and two sub-pixels (sub-pixel 3 and sub-pixel 6) in the third column are blue sub-pixels, each sub-pixel includes a pixel electrode, and each pixel electrode has the same structure and is in a horse-shaped structure. The main body of the pixel electrode with the horse-shaped structure is a bent strip-shaped electrode, two sides of the main body are respectively provided with a connecting electrode, one end part of the connecting electrode is connected with the main body, the other end part of the connecting electrode is far away from the main body, each connecting electrode is parallel to each other and has an inclination angle relative to the main body, and the outline of the horse-shaped pixel electrode is in a parallelogram shape. The transmittance of the display panel can be improved by more than 10% by replacing the straight-bar-shaped pixel electrodes in the current display panel with the horse-shaped pixel electrodes, but because the structure of each pixel electrode in the row direction (second direction) and the column direction (first direction) is the same as that of each pixel electrode in the row direction (second direction) and the horse-shaped pixel electrodes are asymmetric as shown in fig. 1, the oblique directions of the connecting electrodes are all parallel, and a certain viewing angle problem exists.
In addition, when an 8K display device is designed, due to the need to comprehensively consider the design of a Thin Film Transistor (TFT), an isolation Pillar (PS), a via structure and a pixel capacitor, the aperture ratios of two adjacent rows of sub-pixels are not uniform. For example, fig. 2 is a schematic structural diagram of a pixel unit of a common 8K product, as shown in fig. 2, the pixel unit includes 6 sub-pixels, a direction along which the sub-pixels 1 to 4 are arranged is a first direction, a direction along which the sub-pixels 1 to 2 are arranged is a second direction, and the sub-pixels in the same column (arranged parallel to the first direction) have the same color. Since the common electrodes located in different rows need to be electrically connected through a common electrode line, a via structure needs to be provided. For example, as shown in fig. 2, a first via structure 10 is disposed in the sub-pixel 2, and a second via structure 10' is disposed in the sub-pixel 5, but the position of the first via structure 10 in the sub-pixel 2 is different from the position of the second via structure 10' in the sub-pixel 5, the first via structure 10 is located at the upper right corner of the sub-pixel 2 and affects the arrangement of the pixel electrode structure in the sub-pixel 2, and the second via structure 10' is located at the lower right corner of the sub-pixel 5 and does not affect the arrangement of the pixel electrode structure in the sub-pixel 5, so that the aperture ratio of the sub-pixel 2 (e.g., blue sub-pixel) is smaller than the aperture ratio of the sub-pixel 5 (e.g., blue sub-pixel), and therefore, the low gray level pure blue screen has the Mura defect, for example, fig. 3 is a screen with the occurrence of the Mura defect.
At least one embodiment of the present disclosure provides a pixel unit, including: a2 × 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 which are sequentially arranged in a clockwise direction, each sub-pixel area includes sub-pixels, a direction from sub-pixels in the first sub-pixel area to sub-pixels in the fourth sub-pixel area is a first direction, a direction from sub-pixels in the first sub-pixel area to sub-pixels in the second sub-pixel area is a second direction, and in a direction parallel to the first direction, colors of adjacent sub-pixels are the same; each sub-pixel includes a pixel electrode; the pixel electrodes in the first sub-pixel area and the pixel electrodes in the third sub-pixel area are in one-to-one correspondence, and the structures of the pixel electrodes in the first sub-pixel area and the corresponding pixel electrodes in the third sub-pixel area are the same; the pixel electrodes in the second sub-pixel area and the pixel electrodes in the fourth sub-pixel area are in one-to-one correspondence, and the structures of the pixel electrodes in the second sub-pixel area and the corresponding pixel electrodes in the fourth sub-pixel area are the same; the structure of one pixel electrode in the first sub-pixel region is different from the structure of a pixel electrode adjacent to the one pixel electrode in the first direction in the fourth sub-pixel region. The pixel unit can improve the Mura defect on the basis of ensuring high pixel transmittance.
The one-to-one correspondence means that the number of the pixel electrodes in the first sub-pixel region and the number of the pixel electrodes in the third sub-pixel region are equal, and the arrangement mode of the sub-pixels and the color of the corresponding sub-pixels are the same; the number of the pixel electrodes in the second sub-pixel area and the number of the pixel electrodes in the fourth sub-pixel area are equal, and the arrangement mode of the sub-pixels and the colors of the corresponding sub-pixels are the same.
For example, fig. 4 isbase:Sub>A schematic plan structure diagram ofbase:Sub>A pixel unit according to an embodiment of the disclosure, as shown in fig. 4, the pixel unit A1 includesbase:Sub>A 2 × 2 sub-pixel area matrix, the 2 × 2 sub-pixel area matrix includesbase:Sub>A first sub-pixel area L1,base:Sub>A second sub-pixel area L2,base:Sub>A third sub-pixel area L3, andbase:Sub>A fourth sub-pixel area L4 sequentially arranged inbase:Sub>A clockwise direction,base:Sub>A direction from sub-pixels in the first sub-pixel area L1 to sub-pixels in the fourth sub-pixel area L4 isbase:Sub>A first directionbase:Sub>A-base:Sub>A ',base:Sub>A direction from sub-pixels in the first sub-pixel area L1 to sub-pixels in the second sub-pixel area L2 isbase:Sub>A second direction B-B', and each sub-pixel area includesbase:Sub>A sub-pixel P.

Along the first directionbase:Sub>A-base:Sub>A', the colors of the adjacent sub-pixels P are the same, for example, the colors of the first sub-pixel P1 and the twelfth sub-pixel P12 are the same, the colors of the second sub-pixel P2 and the eleventh sub-pixel P11 are the same, the colors of the third sub-pixel P3 and the tenth sub-pixel P10 are the same, the colors of the fourth sub-pixel P4 and the ninth sub-pixel P9 are the same, the colors of the fifth sub-pixel P5 and the eighth sub-pixel P8 are the same, and the colors of the sixth sub-pixel P6 and the seventh sub-pixel P7 are the same.
For example, each sub-pixel P includes a pixel electrode E, the pixel electrodes E1 in the first sub-pixel region L1 and the pixel electrodes E3 in the third sub-pixel region L3 correspond to each other one by one, and the pixel electrodes E1 in the first sub-pixel region L1 and the pixel electrodes E3 corresponding thereto in the third sub-pixel region L3 have the same structure. For example, the color of the first sub-pixel P1 in the first sub-pixel region L1 and the color of the ninth sub-pixel P9 in the third sub-pixel region L3 are the same, and the structure of the pixel electrode E11 in the first sub-pixel region L1 and the structure of the pixel electrode E31 in the third sub-pixel region L3 are the same; the color of the second sub-pixel P2 in the first sub-pixel region L1 is the same as that of the eighth sub-pixel P8 in the third sub-pixel region L3, and the structure of the pixel electrode E12 in the first sub-pixel region L1 is the same as that of the pixel electrode E32 in the third sub-pixel region L3; the third subpixel P3 in the first subpixel region L1 and the seventh subpixel P7 in the third subpixel region L3 have the same color, and the pixel electrode E13 in the first subpixel region L1 and the pixel electrode E33 in the third subpixel region L3 have the same structure.

For example, the arrangement of the plurality of second electrodes E112 along the extending direction of the first electrode E111 means that: the plurality of second electrodes E112 are arranged along the extending direction of the first sub-electrode E111a, or arranged along the extending direction of the third sub-electrode E111 c; or, a part of the second electrode E112 is arranged along the extending direction of the first sub-electrode E111a, and a part of the second electrode E112 is arranged along the extending direction of the third sub-electrode E111 c; or, a portion of the second electrode E112 is arranged along the extending direction of the first sub-electrode E111a, a portion of the second electrode E112 is arranged along the extending direction of the second sub-electrode E111b, and a portion of the second electrode E112 is arranged along the extending direction of the third sub-electrode E111c, which is not limited in this embodiment of the disclosure.
For example, since the second sub-electrode E111b intersects with the first sub-electrode E111a and intersects with the third sub-electrode E111c, the extending direction of the second sub-electrode E111b is not collinear with the extending direction of the first sub-electrode E111a and the extending direction of the third sub-electrode E111 c. Because signal lines are arranged on two sides of the pixel electrode, for example, the signal lines are data lines configured to transmit data signals to the pixel electrode, the extending direction of the second sub-electrode E111b is not collinear with the extending direction of the first sub-electrode E111a and the extending direction of the third sub-electrode E111c, and therefore it can be avoided that the coupling capacitance of the first electrode E111 with the signal line at the closer distance is larger and the coupling capacitance of the signal line at the farther distance is smaller due to the closer distance between the first electrode E111 and one of the signal lines at two sides of the pixel electrode and the farther distance between the first electrode E111 and the other signal line, that is, the coupling capacitance of each region of the display panel formed subsequently is larger in difference, thereby affecting the display effect of the display panel.
It should be noted that the different sides of the second sub-electrode E111b refer to two sides of the main body of the second sub-electrode E111b and a straight line parallel to the extending direction of the second sub-electrode E111b, not two sides of the end portion of the second sub-electrode E111b, and the first sub-electrode E111a and the third sub-electrode E111c are disposed on different sides of the second sub-electrode E111b, so that the second electrode E112 connected to the first electrode E111 can be uniformly distributed on different sides of the second sub-electrode E111b, and when the plurality of second electrodes E112 are parallel to each other, for example, the extending direction of the second electrode is parallel to the first extending direction a-a' in fig. 5, the pixel electrode has good symmetry, and the transmittance of the display panel including the pixel electrode can be highly uniform.
For example, as shown in fig. 5, the plurality of second electrodes E112 includes: a first-type second electrode E112a and a second-type second electrode E112b, wherein a first end E112a1 of the first-type second electrode E112a is connected to the first sub-electrode E111a, and a second end E112a2 of the first-type second electrode E112a is far away from the first sub-electrode E111a; the first end E112b1 of the second type second electrode E112b is connected to the third sub-electrode E111c, the second end E112b2 of the second type second electrode E112b is far away from the third sub-electrode E111c, the first type second electrode E112a and the second type second electrode E112b are located at different sides of the second sub-electrode E111b, and the first type second electrode E112a and the second type second electrode E112b are parallel, for example, in some embodiments, the first type second electrode E112a and the second type second electrode E112b may not be parallel. For example, the second electrode shown in fig. 6 also has the similar structure as described above, except that the extending directions of the first-type second electrode E122a and the second-type second electrode E122b in fig. 6 are both parallel to the second extending direction b-b', which is not described again here.
It should be noted that other pixel electrodes have similar designs as described above, and are not described herein again.
For example, fig. 7A is an enlarged schematic structural diagram of a first electrode according to an embodiment of the disclosure, as shown in fig. 7A, in a first electrode E111, a first sub-electrode E111a is parallel or substantially parallel to a third sub-electrode E111c, so that the overall structure of the pixel electrode can be made symmetrical, and the display effect of the display panel including the pixel structure is better. Due to the limitation of the process conditions, when the angle between the extending direction of the first sub-electrode and the extending direction of the third sub-electrode is in the range of 0 degree to 10 degrees, the first sub-electrode and the third sub-electrode may also be considered to be substantially parallel. For example, a first included angle α between the second sub-electrode E111b and the first sub-electrode E111a is equal to or substantially equal to a second included angle β between the second sub-electrode E111b and the third sub-electrode E111 c.
For example, the included angle α between the second sub-electrode E111b and the first sub-electrode E111a and the included angle β between the second sub-electrode E111b and the third sub-electrode E111c may be both acute angles, both right angles, or both obtuse angles. When the included angle α between the second sub-electrode E111b and the first sub-electrode E111a and the included angle β between the second sub-electrode E111b and the third sub-electrode E111c are both obtuse angles, because the area where the second electrodes E112 are dispersed is larger, the transmittance of the display panel including the pixel electrode under the condition of the same number of second electrodes E112 and the same length of first electrodes E111 is greater than the case where the included angle α between the second sub-electrode E111b and the first sub-electrode E111a and the included angle β between the second sub-electrode E111b and the third sub-electrode E111c are both right angles and acute angles; similarly, when the included angle α between the second sub-electrode E111b and the first sub-electrode E111a and the included 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 that when the included angle α between the second sub-electrode E111b and the first sub-electrode E111a and the included angle β between the second sub-electrode E111b and the third sub-electrode E111c are both acute angles.
For example, fig. 7B is an enlarged schematic structural diagram of another first electrode according to an embodiment of the disclosure, and as shown in fig. 7B, a slit E111B is further disposed in the second sub-electrode E111B, so that the aperture ratio of the pixel electrode can be increased. For example, fig. 7C is an enlarged schematic structural diagram of another first electrode according to an embodiment of the disclosure, and two slits E111b are disposed in the second sub-electrode E111b, so that the aperture ratio of the pixel electrode can be further increased.
For example, in conjunction with fig. 4, 5 and 6, in the first sub-pixel region L1, the pixel electrode in the first sub-pixel P1 includes a plurality of second electrodes E112 having the same extending direction, which are parallel to the first extending direction a-a'; the pixel electrode in the second subpixel P2 includes a plurality of second electrodes E122 extending in the same direction, which are parallel to the second extending direction b-b'. 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 have the same extending direction of the plurality of second electrodes, and are all parallel to the first extending direction a-a'; the pixel electrodes in the fourth, sixth, eighth, tenth and twelfth sub-pixels P4, P6, P8, P10 and P12 include a plurality of second electrodes having the same extending direction, and are parallel to the second extending direction b-b ', and the first extending direction a-a ' and the second extending direction b-b ' cross each other. The included angle between the first extending direction a-a 'and the second extending direction b-b' is two, 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.
For example, as shown in fig. 4, the x axis arranged horizontally and the y axis arranged vertically are perpendicular to each other, the first directionbase:Sub>A-base:Sub>A 'and the y axis are parallel, and the second direction B-B' and the x axis are parallel, and due to the arrangement of the via structure, the isolation column, etc., there isbase:Sub>A slight difference in structure between the pixel electrodes in at least the sub-pixels in the same column in the first sub-pixel region L1 and the fourth sub-pixel region L4, for example, there isbase:Sub>A slight difference in structure between the pixel electrode E12 in the second sub-pixel P2 located at the middle position in the first sub-pixel region L1 and the pixel electrode E42 in the eleventh sub-pixel P11 located at the middle position in the fourth sub-pixel region L4, so that the total sum of the aperture ratios of the three sub-pixels in the first sub-pixel region L1 and the total sum of the aperture ratios of the three sub-pixels in the fourth sub-pixel region L4 are different, but the slight difference in structure is ignored asbase:Sub>A whole.
For example, in one example, the pixel electrodes in two adjacent columns of sub-pixels are axisymmetric, ignoring slight differences in structure. For example, in the first subpixel region L1, the pixel electrode E11 and the pixel electrode E12 in the first subpixel P1 are axisymmetric with respect to the y-axis, and the pixel electrode E12 and the pixel electrode E13 in the first subpixel P1 are axisymmetric with respect to the y-axis. Between the first sub-pixel region L1 and the second sub-pixel region L2, the pixel electrode E13 in the third sub-pixel P3 in the first sub-pixel region L1 and the pixel electrode E21 in the fourth sub-pixel P4 in the second sub-pixel region L2 are axisymmetric with respect to the y-axis, and related designs may also exist in other sub-pixel regions or between sub-pixel regions, which is not described herein again.
For example, in one example, although not shown in fig. 4, the pixel electrodes in the sub-pixels located in the same column in the first and fourth sub-pixel regions L1 and L4 may be substantially axisymmetric, for example, the pixel electrode in the first sub-pixel P1 in the first sub-pixel region L1 and the pixel electrode in the twelfth sub-pixel P12 in the fourth sub-pixel region L4 are axisymmetric about the x-axis; the pixel electrode in the second subpixel P2 in the first subpixel region L1 and the pixel electrode in the eleventh subpixel P11 in the fourth subpixel region L4 are axisymmetric with respect to the x-axis; the pixel electrode in the third sub-pixel P3 in the first sub-pixel region L1 and the pixel electrode in the tenth sub-pixel P10 in the fourth sub-pixel region L4 are axisymmetric with respect to the x-axis, and similarly, the second sub-pixel region L2 and the third sub-pixel region L3 may have an arrangement of the related symmetric structure.
For example, as can be seen from fig. 4, in each sub-pixel of the first sub-pixel region L1, the second sub-pixel region L2, the third sub-pixel region L3, and the fourth sub-pixel region L4, the extending direction of the first electrode in each pixel electrode is parallel to the y-axis, the second electrode in each pixel electrode is inclined at an angle to the y-axis, and the entire sub-pixel is not inclined and is also parallel to the y-axis. For example, in fig. 5, the extending direction of the first electrode E111 in the pixel electrode E11 is parallel to the y-axis, and the extending direction of the second electrode E112 forms an angle with the y-axis.
For example, ignoring a slight difference in structure, the length of each sub-pixel in the first sub-pixel region L1, the second sub-pixel region L2, the third sub-pixel region L3, and the fourth sub-pixel region L4 is equal or substantially equal, the width of each sub-pixel is equal or substantially equal, the length of the second electrode in each pixel electrode in each sub-pixel is equal or substantially equal, and the length of the first electrode in each pixel electrode in each sub-pixel in the y-axis direction is equal or substantially equal.
For example, in each sub-pixel of the first sub-pixel region L1, the second sub-pixel region L2, the third sub-pixel region L3, and the fourth sub-pixel region 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, the plurality of second electrodes with smaller width and smaller length are connected by one first electrode with larger width and longer length to realize the connection of the electrodes.
For example, as shown in fig. 4, each of the first sub-pixel region L1, the second sub-pixel region L2, the third sub-pixel region L3 and the fourth sub-pixel region L4 includes three sub-pixels of a1 × 3 sub-pixel matrix, that is, each of the four sub-pixel regions includes three sub-pixels, that is, each of the first sub-pixel region L1, the second sub-pixel region L2, the third sub-pixel region L3 and the fourth sub-pixel region L4 includes sub-pixels of one row and three columns.
For example, three sub-pixels of the first sub-pixel region, the second sub-pixel region, the third sub-pixel region and the fourth sub-pixel region are a red sub-pixel (R), a green sub-pixel (G) and a blue sub-pixel (B), respectively.
For example, there are various arrangements of the red, green, and blue sub-pixels (R, G, and B), and the red, green, and blue sub-pixels (R, G, and B) may be arranged in any combination; and the arrangement of RGB in the first and fourth sub-pixel regions L1 and L4 is the same, the arrangement of RGB in the second and third sub-pixel regions L2 and L3 is the same, and the arrangement of red, green and blue sub-pixels (R), G and B) in the first and fourth sub-pixel regions L1 and L4 and the second and third sub-pixel regions L2 and L3 may be the same. For example, as shown in fig. 4, the arrangement of RGB in the first sub-pixel region L1 and the fourth sub-pixel region L4 is the same as the arrangement of RGB in the second sub-pixel region L2 and the third sub-pixel region L3, and each of the RGB is a red sub-pixel (R), a green sub-pixel (G), and a blue sub-pixel (B) in this order along the x-axis direction.
For another example, in fig. 5 and 6, 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 the same length, so that the symmetry of the whole structure of the pixel electrode can be ensured, and the uniformity of the transmittance of the display panel including the pixel electrode can be ensured.
For example, fig. 8 is an enlarged schematic structural diagram of another pixel electrode provided in an embodiment of the present disclosure, as shown in fig. 8, an extending direction of the first electrode E111 in each pixel electrode is parallel to a y-axis, the second electrode E112 in each pixel electrode is perpendicular to the y-axis, and the entire sub-pixel is non-oblique and is also flat with the y-axis.
For example, fig. 9 is an enlarged schematic structural diagram of another pixel electrode provided in an embodiment of the present disclosure, an extending direction of the first electrode E121 in each pixel electrode is parallel to a y-axis, the second electrode E122 in each pixel electrode is perpendicular to the y-axis, and the entire sub-pixel is non-oblique and also flat with respect to the y-axis.
For example, a schematic plane structure of a pixel unit formed by combining fig. 8 and 9 is shown in fig. 10, where fig. 10 is a schematic plane structure of a pixel unit according to still another embodiment of the present disclosure, and in the structure shown in fig. 10, compared to the structure shown in fig. 4, except that the second electrode E112 in each pixel electrode is perpendicular to the y-axis, other related descriptions may refer to the above related description related to fig. 4, and are not repeated herein.

For example, as shown in fig. 11 to 13, in the first pixel region L1, there are a first sub-pixel P1 and a second sub-pixel P2 adjacent in the second direction B-B', the pixel electrode E11 in the first sub-pixel P1 is a first pixel electrode E11, and the pixel electrode E12 in the second sub-pixel P2 is a second pixel electrode E12. The extending direction of the first-type second electrode E112a in the second electrodes E112 included in the first pixel electrode E11 and the extending direction of the first-type second electrode E122a in the second electrodes E122 included in the second pixel electrode E12 intersect each other, and the extending direction of the second-type second electrode E112b in the second electrodes E112 included in the first pixel electrode E11 and the extending direction of the second-type second electrode E122b in the second electrodes E122 included in the second pixel electrode E12 intersect each other.
For example, fig. 14 is a schematic plan structure diagram of another pixel unit according to an embodiment of the disclosure, and fig. 15 is an enlarged schematic structural diagram of one pixel electrode in fig. 14, and with reference to fig. 14 and fig. 15, the first type second electrodes E112a are not parallel to the second type second electrodes E112b, the plurality of second electrodes E112 further include a third type second electrode E112c, a first end E112c1 of the third type second electrode E112c is connected to the second sub-electrode E111b, and a second end E112c2 of the third type second electrode E112c is far away from the second sub-electrode E111b.
For example, as shown in fig. 15, 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 E111 a.
Alternatively, fig. 16 is an enlarged schematic structural view of another pixel electrode in fig. 14 according to an embodiment of the disclosure, as shown in fig. 16, 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 E121 b.
For example,base:Sub>A schematic plan structure ofbase:Sub>A pixel unit formed by combining fig. 15 and fig. 16 is shown in fig. 14, and in combination with fig. 14, fig. 15 and fig. 16, inbase:Sub>A first sub-pixel P1 andbase:Sub>A second sub-pixel P2 adjacent in the first directionbase:Sub>A-base:Sub>A', the first sub-pixel P1 includesbase:Sub>A first pixel electrode E11, and the second sub-pixel P2 includesbase:Sub>A second pixel electrode E12; the extending direction of the first type second electrode E112a in the second electrodes E112 included in the first pixel electrode E11 and the extending direction of the first type second electrode E122a in the second electrodes E122 included in the second pixel electrode E12 intersect; the extending direction of the second type of second electrode E112b in the second electrodes E112 included in the first pixel electrode E11 and the extending direction of the second type of second electrode E122b in the second electrodes E122 included in the second pixel electrode E12 intersect; the extending direction of the third type of second electrode E112c among the second electrodes E112 included in the first pixel electrode E11 and the extending direction of the third type of second electrode E122c among the second electrodes E122 included in the second pixel electrode E12 intersect.
For example, in fig. 15, the first-type second electrodes E112a are arranged along the extending direction of the first sub-electrodes E111a, the third-type second electrodes E112c are arranged along the extending direction of the second sub-electrodes E111b, and the second-type second electrodes E112b are arranged along the extending direction of the third sub-electrodes E111 c.

Similarly, fig. 16 also has the similar structure and position relationship, and the description thereof is omitted here.
For example, fig. 17 isbase:Sub>A schematic plan view of another pixel unit provided by an embodiment of the present disclosure, and as shown in fig. 17, each of the four sub-pixel regions includes four sub-pixels formingbase:Sub>A 1 × 4 sub-pixel matrix, that is, each of the four sub-pixel regions includes four sub-pixels, and each of the four sub-pixel regions includesbase:Sub>A 1 × 4 sub-pixel matrix, that is, the color of the sub-pixels in the same column (the column direction isbase:Sub>A direction parallel to the first directionbase:Sub>A-base:Sub>A') in the first sub-pixel region L1 and the fourth sub-pixel region L4 is the same, and the color of the sub-pixels in the same column in the second sub-pixel region L2 and the third sub-pixel region L3 is the same. Four sub-pixels in the four sub-pixel regions are a red sub-pixel (R), a green sub-pixel (G), a blue sub-pixel (B), and a white sub-pixel (W), respectively. The arrangement modes of R, G, B and W are various, and the R, G, B and W can be arranged in any combination; the RGBW arrangement in the first sub-pixel region L1 and the fourth sub-pixel region L4 is the same, the RGBW arrangement in the second sub-pixel region L2 and the third sub-pixel region L3 is the same, and the RGBW arrangement in the first sub-pixel region L1 and the fourth sub-pixel region L4 and the second sub-pixel region L2 and the third sub-pixel region L3 may be the same; as shown in fig. 17, RGBW is arranged in the first sub-pixel region L1 and the fourth sub-pixel region L4 in the same manner as in the second sub-pixel region L2 and the third sub-pixel region L3, and both are RGBW.

It should be noted that, in addition to the related structures described in the foregoing embodiments, in the embodiments of the present disclosure, the pixel electrode included in each sub-pixel may also be inclined, and a certain included angle exists between the extending direction of the first electrode and the y-axis, so that the whole sub-pixel is also inclined, and the inclined directions of the sub-pixel and the pixel electrode are the same, and details are not repeated.
For example, fig. 18 is a picture of the pixel unit shown in fig. 4, 10, 13, 14 and 17 when used for normal display in a display panel, and it can be seen from fig. 18 that the striations Mura are not present.
At least one embodiment of the present disclosure further provides an array substrate, where the array substrate includes a plurality of pixel units, gate lines, data lines, and thin film transistors disposed in each sub-pixel, and the pixel units are arranged in an array.
For example, fig. 19 is a schematic plan structure view of an array substrate according to an embodiment of the disclosure, and as shown in fig. 19, the array substrate includes: twelve thin film transistors are respectively arranged in each sub-pixel, namely, one thin film transistor is arranged in each sub-pixel, and each thin film transistor comprises a source electrode and a drain electrode.

The same data line is electrically connected to the sub-pixels in the same column, for example, the first data line D1 is electrically connected to the first sub-pixel P1 and the twelfth sub-pixel P12; the second data line D2 is electrically connected to the second and eleventh sub-pixels P2 and P11, the third data line D3 is electrically connected to the third and tenth sub-pixels P3 and P10, the fourth data line D4 is electrically connected to the fourth and ninth sub-pixels P4 and P9, the fifth data line D5 is electrically connected to the fifth and eighth sub-pixels P5 and P8, and the sixth data line D6 is electrically connected to the seventh sub-pixel P7.
