Detailed ways

In order to make the purpose, 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 accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Unless otherwise defined, technical or scientific terms used in this disclosure should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. As used in this disclosure, "first," "second," and similar terms do not denote any order, quantity, or importance, but are merely used to distinguish the various components. "Comprises" or "comprising" and similar words mean that the elements or things appearing before the word encompass the elements or things recited after the word and their equivalents, but do not exclude other elements or things. Words like "connected" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "Down", "Left", "Right", etc. are only used to represent the relative positional relationship, and when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

8K resolution is an experimental digital video standard with a resolution of 7680×4320 pixels. K refers to kilo (kilo), that is, the number of pixels in the horizontal direction is several thousand. The pixels displayed by the 8K resolution display device are four times that of the 4K resolution display device. The resolution of the current mainstream High Definition TV (HDTV) is 1920×1080, that is, the 8K resolution display is higher than the current mainstream high definition TV (High Definition TV, HDTV). HDTVs have 16 times the resolution.

In the current 8K display device, due to the high resolution (PPI) of the 8K display device and the small pixels, the overall aperture ratio of the 8K display device is low, resulting in a low transmittance. The display panel includes pixel units, each pixel unit includes a plurality of pixel structures, and each pixel structure 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, and the direction along which sub-pixels 1 to 4 are arranged is the first direction. The direction in which the sub-pixels 2 are arranged is the second direction, and they are located in the same column, that is, the sub-pixels 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-shaped structure. The main body of the pixel electrode with the horse-shaped structure is a bent strip electrode, and connection electrodes are respectively provided on both sides of the main body. One end of the connection electrode is connected to the main body, and the other end of the connection electrode is far away from the main body. Each of the connection electrodes is parallel to each other and has an inclined angle relative to the main body, and the shape of the outer contour of the horse-shaped pixel electrode is a parallelogram. Replacing the pixel electrodes of the straight structure in the current display panel with the pixel electrodes of the horse-shaped structure can increase the transmittance of the display panel by more than 10%. However, as shown in FIG. ) and the column direction (first direction) have the same structure of each pixel electrode, and since the horse-shaped pixel structure is asymmetric, the inclination directions of the connecting electrodes are parallel, and there will be a certain viewing angle problem.

In addition, when designing 8K display devices, due to the need to comprehensively consider the design of thin film transistors (TFTs), spacers (PS), via structures and pixel capacitances, the aperture ratios of two adjacent rows of sub-pixels are usually inconsistent. . For example, FIG. 2 is a schematic diagram of the structure of a common 8K product pixel unit. As shown in FIG. 2 , the pixel unit includes 6 sub-pixels, and the direction along which sub-pixels 1 to 4 are arranged is the first direction. The direction in which the pixel 1 to the sub-pixel 2 are arranged is the second direction, and the sub-pixels located in the same column (arranged parallel to the first direction) have the same color. Since common electrodes located in different rows need to be electrically connected through common electrode lines, a via structure needs to be provided. For example, as shown in FIG. 2 , the sub-pixel 2 is provided with a first via structure 10 , and the sub-pixel 5 is provided with a second via structure 10 ′, but the first via structure 10 is provided in the sub-pixel 2 The position of the second via hole structure 10' is different from the position of the second via hole structure 10' in the subpixel 5. The first via hole structure 10 is located in the upper right corner of the subpixel 2 and affects the arrangement of the pixel electrode structure in the subpixel 2. The second via hole 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 (eg, a blue sub-pixel) is smaller than that of the sub-pixel 5 (eg, a blue sub-pixel) The aperture ratio is 100%, so that the low grayscale pure blue picture has poor horizontal streak Mura. For example, Figure 3 shows the picture when horizontal streak Mura occurs.

At least one embodiment of the present disclosure provides a pixel unit, the pixel unit 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 arranged in sequence in a clockwise direction The second sub-pixel area, the third sub-pixel area and the fourth sub-pixel area, each sub-pixel area includes sub-pixels, and the direction from the sub-pixels in the first sub-pixel area to the sub-pixels in the fourth sub-pixel area is the first direction , the direction from the sub-pixels in the first sub-pixel area to the sub-pixels in the second sub-pixel area is the second direction, and in the direction parallel to the first direction, adjacent sub-pixels have the same color; each sub-pixel includes a pixel Electrodes; 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 structure of the pixel electrodes in the first sub-pixel area and the corresponding pixel electrodes in the third sub-pixel area 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 structure of the pixel electrodes in the second sub-pixel area and the corresponding pixel electrodes in the fourth sub-pixel area The same; the structure of one pixel electrode in the first sub-pixel region and the structure of the pixel electrode adjacent to the one pixel electrode along the first direction in the fourth sub-pixel region are different. The pixel unit can improve the horizontal Mura defect on the basis of ensuring high pixel transmittance.

It should be noted that the 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 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 the same, and the arrangement of the sub-pixels and the colors of the corresponding sub-pixels are the same.

For example, FIG. 4 is a schematic plan view of a pixel unit according to an embodiment of the present disclosure. As shown in FIG. 4 , the pixel unit A1 includes a 2×2 sub-pixel area matrix, and the 2×2 sub-pixel area matrix includes 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 arranged in sequence in the clockwise direction, the sub-pixels in the first sub-pixel area L1 to the fourth sub-pixel area The direction of the sub-pixels in L4 is the first direction AA', the direction of the sub-pixels in the first sub-pixel area L1 to the sub-pixels in the second sub-pixel area L2 is the second direction BB', each sub-pixel The pixel region includes sub-pixels P.

For example, as shown in FIG. 4 , the first sub-pixel area L1 includes a first sub-pixel P1, a second sub-pixel P2 and a third sub-pixel P3, and the second sub-pixel area L2 includes a fourth sub-pixel P4 and a fifth sub-pixel P5 and the sixth subpixel P6, the third subpixel area L3 includes the seventh subpixel P7, the eighth subpixel P8 and the ninth subpixel P9, the fourth subpixel area L4 includes the tenth subpixel P10, the eleventh subpixel The pixel P11 and the twelfth sub-pixel P12. Along the first direction AA', adjacent sub-pixels P have the same color, for example, the first sub-pixel P1 and the twelfth sub-pixel P12 have the same color, and the second sub-pixel P2 and the eleventh sub-pixel P11 have the same color The colors of the third sub-pixel P3 and the tenth sub-pixel P10 are the same, the fourth sub-pixel P4 and the ninth sub-pixel P9 are the same color, the fifth sub-pixel P5 and the eighth sub-pixel P8 have the same color, the The six sub-pixels P6 and the seventh sub-pixel P7 have the same color.

For example, each sub-pixel P includes a pixel electrode E, the pixel electrode E1 in the first sub-pixel region L1 and the pixel electrode E3 in the third sub-pixel region L3 are in one-to-one correspondence, and the pixel electrode E1 in the first sub-pixel region L1 The structure is the same as that of the corresponding pixel electrode E3 in the third sub-pixel region L3. For example, the first sub-pixel P1 in the first sub-pixel area L1 and the ninth sub-pixel P9 in the third sub-pixel area L3 have the same color, and the pixel electrode E11 and the third sub-pixel in the first sub-pixel area L1 The structure of the pixel electrode E31 in the area L3 is the same; the color of the second subpixel P2 in the first subpixel area L1 and the eighth subpixel P8 in the third subpixel area L3 are the same, and in the first subpixel area L1 The pixel electrode E12 and the pixel electrode E32 in the third sub-pixel area L3 have the same structure; the third sub-pixel P3 in the first sub-pixel area L1 and the seventh sub-pixel P7 in the third sub-pixel area L3 have the same color , and the structure of the pixel electrode E13 in the first sub-pixel region L1 and the pixel electrode E33 in the third sub-pixel region L3 is the same.

For example, the pixel electrodes E2 in the second sub-pixel region L2 and the pixel electrodes E4 in the fourth sub-pixel region L4 are in one-to-one correspondence, and the pixel electrodes E2 in the second sub-pixel region L2 and the fourth sub-pixel region L4 are in The corresponding pixel electrodes E4 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 second sub-pixel area The pixel electrode E21 in 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 The colors are the same, and the structure of the pixel electrode E22 in the second sub-pixel area L2 and the pixel electrode E42 in the fourth sub-pixel area L4 are the same; the sixth sub-pixel P6 in the second sub-pixel area L2 and the fourth sub-pixel The tenth sub-pixel P10 in the area L4 has 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.

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

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

For example, FIG. 5 is an enlarged schematic diagram of a pixel electrode in FIG. 4 , and FIG. 5 takes the pixel electrode E11 as an example for illustration. The pixel electrode includes a first electrode E111 and a plurality of second electrodes E112 , each of which is It is connected to the first electrode E111, and the second electrode E112 is arranged along the extending direction C of the first electrode E111. FIG. 6 is an enlarged schematic view of another pixel electrode in FIG. 4 . FIG. 6 is illustrated by taking the pixel electrode E12 as an example. The pixel electrode includes a first electrode E121 and a plurality of second electrodes E122 , each of which is connected to The first electrodes E121 are connected, and the second electrodes E122 are arranged along the extending direction C of the first electrodes E121.

For example, the first electrode is in a zigzag shape, 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, and the other end of the second sub-electrode is connected One end 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. As shown in FIG. 5 , the first electrode E111 is in a zigzag shape. For example, the structure of the first electrode E111 is a vertical "Z"-shaped structure. The first electrode E111 includes: a first sub-electrode E111a, a second sub-electrode E111b and The third sub-electrode E111c, one end of the first sub-electrode E111a is connected to one end of the second sub-electrode E111b, 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 The electrodes E111c are located on different sides of the second sub-electrodes 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.

For example, the arrangement of the plurality of second electrodes E112 along the extension direction of the first electrode E111 means that the plurality of second electrodes E112 are arranged along the extension direction of the first sub-electrode E111a, or 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 Arranged along the extension direction of the first sub-electrode E111a, part of the second electrode E112 is arranged along the extension direction of the second sub-electrode E111b, and part of the second electrode E112 is arranged along the extension direction of the third sub-electrode E111c, the implementation of the present disclosure The example does not limit this.

For example, since the second sub-electrode E111b intersects with the first sub-electrode E111a and intersects with the third sub-electrode E111c, the extension direction of the second sub-electrode E111b is the same as the extension direction of the first sub-electrode E111a and the third sub-electrode E111b. The extending directions of E111c are not collinear. Since there are signal lines on both sides of the pixel electrode, for example, the signal line is a data line, and the data line is configured to transmit data signals for the pixel electrode. Therefore, the extension direction of the second sub-electrode E111b is the same as the extension direction of the first sub-electrode E111a. and the extension of the third sub-electrode E111c are not collinear, which can avoid that the distance between the first electrode E111 and one of the signal lines on both sides of the pixel electrode is relatively short, and the distance with the other signal line is relatively short. The distance between the first electrode E111 and the signal line with a short distance is large, and the coupling capacitance with the signal line with a long distance is small, that is, the coupling capacitance of each area of the display panel formed subsequently is relatively large. Thus, the display effect of the display panel is affected.

It should be noted that the above-mentioned 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 extending direction of the second sub-electrode E111b, rather than 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 electrode E112 connected to the first electrode E111 can be distributed evenly on the second sub-electrode E111b. On different sides of the sub-electrodes E111b, when the plurality of second electrodes E112 are parallel to each other, for example, the extending directions of the second electrodes in FIG. 5 are all parallel to the first extending directions a-a', the symmetry of the pixel electrodes is good, The uniformity of transmittance of the display panel including the pixel electrode can be made higher.

For example, as shown in FIG. 5 , the plurality of second electrodes E112 include: a first type of second electrode E112a and a second type of second electrode E112b, the first end E112a1 of the first type of second electrode E112a and the first sub-electrode E112a The electrode E111a is connected, the second end E112a2 of the first type second electrode E112a is 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, and the second type second electrode E112b is connected to the third sub-electrode E111c. The second end E112b2 of the electrode E112b is away from the third sub-electrode E111c, the first-type second electrode E112a and the second-type second electrode E112b are located on different sides of the second sub-electrode E111b, the first-type second electrode E112a and the second-type second electrode E112a The second-type electrodes E112b are parallel. For example, in some embodiments, the first-type second electrodes E112a and the second-type second electrodes E112b may not be parallel. For example, the second electrode shown in FIG. 6 also has the above-mentioned similar structure, except that the extension directions of the first type second electrodes E122a and the second type second electrodes E122b in FIG. 6 are both parallel to the second extension direction bb' , and will not be repeated here.

It should be noted that other pixel electrodes also have designs similar to the above, which are not repeated here.

For example, FIG. 7A is an enlarged schematic structural diagram of a first electrode provided by an embodiment of the present disclosure. As shown in FIG. 7A , in a first electrode E111 , the first sub-electrode E111a and the third sub-electrode E111c are parallel or substantially parallel to each other. In parallel, the overall structure of the pixel electrode can be made symmetrical, so that the display panel including the pixel structure has a better display effect. Due to the limitation of process conditions, when the included 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 degrees to 10 degrees, it can also be considered that the first sub-electrode and the third sub-electrode are roughly parallel. For example, the first angle α between the second sub-electrode E111b and the first sub-electrode E111a is equal to or approximately equal to the second angle β between the second sub-electrode E111b and the third sub-electrode E111c.

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 acute angles, right angles or 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 second electrode E112 is dispersed in a larger area, it is possible to Under the condition of the same number of second electrodes E112 and the same length of the first electrodes E111, the transmittance of the display panel including the pixel electrode is greater than the angle α and In the case where the angle β between the second sub-electrode E111b and the third sub-electrode E111c is both 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 α between the second sub-electrode E111b and the first sub-electrode E111b When the included angle β of the three sub-electrodes E111c is a right angle, the transmittance of the display panel including the pixel electrode is greater than the included angle α between the second sub-electrode E111b and the first sub-electrode E111a and the second sub-electrode and the third sub-electrode The included angles β of E111c are all acute angles.

For example, FIG. 7B is an enlarged schematic structural diagram of still another first electrode provided by an embodiment of the present disclosure. As shown in FIG. 7B , a slit E111b is further provided in the second sub-electrode E111b, thereby increasing the number of pixel electrodes. opening rate. For example, FIG. 7C is an enlarged schematic diagram of another first electrode according to 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.

For example, referring to FIG. 4 , FIG. 5 and FIG. 6 , in the first sub-pixel region L1 , the extending directions of the plurality of second electrodes E112 included in the pixel electrodes in the first sub-pixel P1 are the same as the first extending direction a. -a' is parallel; the extension directions of the plurality of second electrodes E122 included in the pixel electrode in the second sub-pixel P2 are the same, and all are parallel to the second extension direction bb'. Similarly, the extension directions of the plurality of second electrodes included in 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 are the same, All are 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 multiple The extending directions of the second electrodes are the same and are parallel to the second extending directions bb', and the first extending directions a-a' and the second extending directions bb' intersect each other. There are two included angles between the first extension direction a-a' and the second extension direction b-b', one is an acute angle and the other is an obtuse angle, and the acute angle is greater than 0 degrees and less than or equal to 90 degrees.

For example, as shown in Figure 4, the horizontally arranged x-axis and the vertically arranged y-axis are perpendicular to each other, the first direction AA' and the y-axis are parallel, and the second direction BB' and the x-axis are parallel. Via structures, isolation columns, etc., will cause slight differences in the structure of the pixel electrodes in the sub-pixels located at least in the same column in the first sub-pixel area L1 and the fourth sub-pixel area L4. For example, the first sub-pixel area There is a slight difference in structure between the pixel electrode E12 in the second sub-pixel P2 in the middle position in L1 and the pixel electrode E42 in the eleventh sub-pixel P11 in the middle position in the fourth sub-pixel region L4, which causes the first The sum of the aperture ratios of the three sub-pixels in the one sub-pixel region L1 and the sum of the aperture ratios of the three sub-pixels in the fourth sub-pixel region L4 are different, but the slight structural difference is ignored as a whole.

For example, in one example, ignoring slight differences in structure, the pixel electrodes in two adjacent columns of sub-pixels are axially symmetric. For example, in the first sub-pixel region L1, the pixel electrode E11 and the pixel electrode E12 in the first sub-pixel P1 are axially symmetric with respect to the y-axis, and the pixel electrode E12 and the pixel electrode E13 in the first sub-pixel P1 are axially symmetrical with respect to the y-axis. Axisymmetric. 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 pixels in the fourth sub-pixel P4 in the second sub-pixel area L2 The electrode E21 is axially symmetric with respect to the y-axis, and related designs may also exist in other sub-pixel regions or between sub-pixel regions, which will not be repeated here.

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 sub-pixel area L1 and the fourth sub-pixel area L4 may be approximately axisymmetric, for example, The pixel electrodes in the first sub-pixel P1 in the first sub-pixel area L1 and the pixel electrodes in the twelfth sub-pixel P12 in the fourth sub-pixel area L4 are axially symmetric with respect to the x-axis; in the first sub-pixel area L1 The pixel electrode in the second sub-pixel P2 and the pixel electrode in the eleventh sub-pixel P11 in the fourth sub-pixel area L4 are axially symmetrical about the x-axis; in the third sub-pixel P3 in the first sub-pixel area L1 The pixel electrode in the fourth sub-pixel region L4 and the pixel electrode in the tenth sub-pixel P10 in the fourth sub-pixel region L4 are axially symmetrical with respect to the x-axis. Similarly, the second sub-pixel region L2 and the third sub-pixel region L3 may also have related symmetrical structures. setting.

For example, it can be seen from FIG. 4 that in each of the sub-pixels 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 The extension direction of the first 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 not inclined and is also parallel to the y-axis. For example, the extending direction of the first electrode E111 in the pixel electrode E11 in FIG. 5 is parallel to the y-axis, and the extending direction of the second electrode E112 forms a certain angle with the y-axis.

For example, ignoring slight differences in structure, the lengths 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 are 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 first electrode in each pixel electrode in each sub-pixel is along y The lengths in the axial direction are also equal or approximately equal.

For example, in each sub-pixel of 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 The length of the second electrode connected to the first electrode, the width of the first electrode is greater than the width of any second electrode connected to the first electrode, that is, through a first electrode with a wider width and a longer length, more A second electrode with a narrow width and a short length is connected to realize the connection of each electrode. The pixel electrode can effectively improve the transmittance of the subsequently formed display panel on the premise of ensuring a low risk of breakage.

For example, as shown in FIG. 4 , 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 all include three sub-pixels in a 1×3 sub-pixel matrix, that is, four sub-pixels. The sub-pixel regions respectively include three sub-pixels, that is, 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 respectively include sub-pixels in one row and three columns.

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

For example, there are various arrangements of red sub-pixels (R), green sub-pixels (G) and blue sub-pixels (B), and 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, and the arrangement of RGB in the second sub-pixel area L2 and the third sub-pixel area L3 is the same, While the red sub-pixels (R), green sub-pixels (G) and blue sub-pixels (B) of 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 arranged in the same way. For example, as shown in FIG. 4 , 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. In the x-axis direction, the red sub-pixel (R), the green sub-pixel (G), and the blue sub-pixel (B) are in sequence.

For another example, in FIG. 5 and FIG. 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, which can ensure the overall structure of the pixel electrode. the symmetry, thereby ensuring the uniformity of the transmittance of the display panel including the pixel electrode.
