[0002] Glasses-free 3D display technology, with its advantages of not requiring auxiliary devices and enabling immersive stereoscopic vision, has been rapidly adopted in commercial displays, automotive instruments, and consumer electronics. Current mainstream glasses-free 3D solutions employ parallax barriers or cylindrical lens structures, using optical beam splitting to separate the parallax between the left and right eyes, thereby reconstructing stereoscopic vision.

[0003] However, due to the periodic arrangement of pixels, LCD panels are prone to producing noticeable periodic black lines. When LCD panels are used in glasses-free 3D displays, these black lines are further exacerbated.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0032] According to the first aspect of this application, Figures 1 to 5 As shown, a display panel 1 is provided, including a plurality of sub-pixels 1a arranged along a first direction D1 and a second direction D2. The second direction D2 intersects the first direction D1. Each sub-pixel 1a includes a pixel electrode 10, which includes a main electrode 11 and a plurality of branch electrodes 12. The main electrode 11 extends along the first direction D1, and the plurality of branch electrodes 12 are arranged along the first direction D1. One end of each branch electrode 12 is connected to the main electrode 11, and the other end of each branch electrode 12 extends in a direction away from the main electrode 11. In the same sub-pixel 1a, the extension directions of two adjacent branch electrodes 12 along the first direction D1 are the same, and the extension directions of two adjacent sub-pixels 1a along the first direction D1 are also the same.

[0033] In some embodiments, the display panel 1 may be a liquid crystal display (LCD) panel or the like. For example, the display panel 1 may be a vertical alignment (VA) type panel. When the display panel 1 is a VA type panel, the pixel electrode 10 and the common electrode layer 20 may be disposed on different sides of the liquid crystal layer.

[0034] like Figure 1As shown, the display panel 1 includes a display area AA and a non-display area NA disposed around the periphery of the display area AA. The display area AA can be provided with multiple sub-pixels 1a, which can include red sub-pixels, green sub-pixels, and blue sub-pixels, thereby realizing color display. The display area AA is provided with a pixel driving circuit, which is used to drive the sub-pixels 1a to display. The non-display area NA can be provided with a gate driving circuit, etc., which can provide driving signals for the sub-pixels 1a.

[0035] In some embodiments, the display panel 1 includes a first substrate and a second substrate facing each other, and a liquid crystal layer disposed between the first substrate and the second substrate.

[0036] like Figures 2 to 5 As shown, Figures 2 to 5 Only a portion of the film structure of sub-pixel 1a is shown. Sub-pixel 1a includes a pixel electrode 10, with one pixel electrode 10 corresponding to one sub-pixel 1a. Sub-pixel 1a also includes a common electrode layer 20 disposed separately from the pixel electrode 10. Liquid crystal molecules in the liquid crystal layer can be deflected under the influence of the electric fields of the pixel electrode 10 and the common electrode layer 20. Liquid crystal molecules with different deflection angles have different light transmittances, thereby adjusting the brightness of the display panel 1. The common electrode layer 20 can be a single, continuous layer. Figures 2 to 4 Only a local area of ​​the common electrode layer 20 is shown in the figure.

[0037] It should be noted that LCD panels themselves do not emit light; therefore, a planar light source, such as a backlight, needs to be placed on one side of the LCD panel. The LCD panel controls the transmittance of the light emitted from the backlight, thereby controlling the brightness changes of the image.

[0038] In some embodiments, such as Figures 2 to 5 As shown, the pixel electrode 10 includes a main electrode 11 and a plurality of branch electrodes 12. The main electrode 11 extends along a first direction D1, and the plurality of branch electrodes 12 are arranged along the first direction D1. The ends of the plurality of branch electrodes 12 closest to the main electrode 11 are all directly connected to the main electrode 11. The other ends of the branch electrodes 12 extend in a direction away from the main electrode 11.

[0039] It should be noted that each branch electrode 12 is directly connected to the main electrode 11. The main electrode 11 of the pixel electrode 10 extends along the first direction D1, and the pixel electrode 10 does not have a main electrode 11 extending in other directions. Since the light transmittance of the area corresponding to the main electrode 11 is lower than that of the area outside the main electrode 11 in the pixel electrode 10, black lines will form in the area with low light transmittance. By setting the pixel electrode 10 to include only the main electrode 11 extending along the first direction D1, the black lines caused by adding main electrodes 11 extending in other directions can be avoided, thereby mitigating the black line phenomenon.

[0040] like Figures 2 to 5 As shown, in the same sub-pixel 1a, the extension directions of two adjacent branch electrodes 12 along the first direction D1 are the same. Through this arrangement, the deflection directions of the liquid crystal molecules in the regions corresponding to multiple branch electrodes 12 can be made the same.

[0041] like Figures 2 to 5 As shown, in two adjacent sub-pixels 1a along the first direction D1, the branch electrodes 12 extend in the same direction. Since the branch electrodes 12 of two adjacent sub-pixels 1a extend in the same direction, the deflection direction of the liquid crystal molecules in the region between the two pixel electrodes 10 is consistent with the deflection direction of the liquid crystal molecules in the region of the pixel electrode 10, thereby improving the black lines between two adjacent sub-pixels 1a along the first direction D1. This is because when the deflection direction of the liquid crystal molecules in the region between the two pixel electrodes 10 is inconsistent with the deflection direction of the liquid crystal molecules in the region of the pixel electrode 10, the liquid crystal molecules, due to their different deflection directions, squeeze each other, preventing them from deflecting to a preset angle. When the liquid crystal molecules cannot deflect to the preset angle, the light transmittance decreases, easily leading to black lines in the region between the two pixel electrodes 10.

[0042] In some embodiments, such as Figures 2 to 5 As shown, the first direction D1 can be the row direction of the display panel 1, and the second direction D2 can be the column direction of the display panel 1. This can improve the vertical black lines in the area between two adjacent sub-pixels 1a.

[0043] In some embodiments, the first direction D1 can be the column direction of the display panel 1, and the second direction D2 can be the row direction of the display panel 1. In this case, the horizontal black lines in the area between two adjacent sub-pixels 1a can be improved.

[0044] In other embodiments, the first direction D1 and the second direction D2 may also be other directions, and this application does not limit them.

[0045] Optionally, such as Figure 2 As shown, in the same sub-pixel 1a, the main electrode 11 has a branch electrode 12 on only one side, and the extension directions of the branch electrodes 12 are all the same.

[0046] In some embodiments, such as Figure 2 As shown, the main electrode 11 has a branch electrode 12 on only one side, and no branch electrode 12 is provided on the other side. That is, the sub-pixel 1a has a single-domain structure, and the liquid crystal molecules in a pixel electrode 10 have only one deflection direction. With the above configuration, the structure of the pixel electrode 10 can be simplified, and the manufacturing difficulty of the display panel 1 can be reduced.

[0047] Optionally, such as Figure 2As shown, in two adjacent sub-pixels 1a in the second direction D2, the branch electrodes 12 extend in different directions. This arrangement expands the viewing angle of the display panel 1.

[0048] In some embodiments, in two adjacent sub-pixels 1a in the second direction D2, the angle between the branch electrode 12 and the main electrode 11 of one sub-pixel 1a can be -45 degrees, and the angle between the branch electrode 12 and the main electrode 11 of the other sub-pixel 1a can be -135 degrees. The angle between the branch electrode 12 and the main electrode 11 can also be other angles, which are not limited in this application.

[0049] Optionally, such as Figures 3 to 5 As shown, in the same sub-pixel 1a, branch electrodes 12 are provided on both sides of the main electrode 11 in the second direction D2. The branch electrodes 12 located on the same side of the main electrode 11 have the same extension direction, while the branch electrodes 12 located on different sides of the main electrode 11 have different extension directions.

[0050] In some embodiments, such as Figures 3 to 5 As shown, branch electrodes 12 are provided on both sides of the main electrode 11, and the branch electrodes 12 on both sides of the main electrode 11 can be symmetrically arranged about the center line of the main electrode 11. With the above arrangement, the sub-pixel 1a can form a dual-domain structure.

[0051] In some embodiments, the angle between the branch electrode 12 on one side of the main electrode 11 and the main electrode 11 is 45 degrees, and the angle between the branch electrode 12 on the other side of the main electrode 11 and the main electrode 11 is -45 degrees. The angle between the branch electrode 12 and the main electrode 11 can also be other angles, and this application does not limit this.

[0052] Optionally, such as Figure 4 As shown, in two adjacent sub-pixels 1a in the second direction D2, the pixel electrode 10 is arranged axially symmetrically about an axis parallel to the first direction D1.

[0053] In some embodiments, such as Figures 3 to 5 As shown, the first direction D1 can be the row direction of the display panel 1, and the second direction D2 can be the column direction of the display panel 1. In two adjacent sub-pixels 1a in the second direction D2, the pixel electrodes 10 are arranged symmetrically about an axis parallel to the first direction D1. That is to say, the pixel electrodes 10 of the sub-pixels 1a in the second row are the same as the pixel electrodes 10 of the sub-pixels 1a in the first row.

[0054] Optionally, such as Figure 3 As shown, in two adjacent sub-pixels 1a in the second direction D2, the extension directions of the branch electrodes 12 located between the two main electrodes 11 are parallel.

[0055] In some embodiments, such as Figure 3 As shown, in two adjacent sub-pixels 1a in the second direction D2, the branch electrode 12 of one sub-pixel 1a extends to the right and the branch electrode 12 of the other sub-pixel 1a extends to the left, that is, the extension directions of the branch electrodes 12 of the two adjacent sub-pixels 1a in the second direction D2 are opposite.

[0056] In some embodiments, in two adjacent sub-pixels 1a in the second direction D2, the branch electrodes 12 on both sides of the main electrode 11 of one sub-pixel 1a form angles of 45 degrees and -45 degrees with the main electrode 11, respectively. The branch electrodes 12 on both sides of the main electrode 11 of the other sub-pixel 1a form angles of 135 degrees and -135 degrees with the main electrode 11, respectively.

[0057] In some embodiments, such as Figure 3 As shown, in two adjacent sub-pixels 1a in the second direction D2, the extension directions of the branch electrodes 12 located between the two main electrodes 11 are parallel. That is, the extension direction of the branch electrode 12 below the main electrode 11 of the first row of sub-pixels 1a is parallel to the extension direction of the branch electrode 12 above the main electrode 11 of the second row of sub-pixels 1a. With this arrangement, the deflection direction of the liquid crystal in the region between two adjacent pixel electrodes 10 in the second direction D2 can be aligned with the deflection direction of the liquid crystal molecules in the region of pixel electrode 10, thereby improving the light transmittance of the region between two adjacent pixel electrodes 10 in the second direction D2 and reducing black lines between two adjacent sub-pixels 1a in the second direction D2.

[0058] Optionally, such as Figure 5 As shown, the pixel electrode 10 also includes an edge electrode 13, which extends in the same direction as the main electrode 11, and the end of the branch electrode 12 away from the main electrode 11 is connected to the edge electrode 13.

[0059] In some embodiments, the pixel electrode 10 further includes an edge electrode 13, the edge electrode 13 extending in the same direction as the main electrode 11. This configuration prevents the edge electrode 13 from causing dark lines in other directions.

[0060] In some embodiments, the main electrode 11 of the pixel electrode 10 is provided with a branch electrode 12 on only one side, and the edge electrode 13 is connected to the end of the multiple branch electrodes 12 away from the main electrode 11.

[0061] In some embodiments, such as Figure 5As shown, branch electrodes 12 are provided on both sides of the main electrode 11 of the pixel electrode 10, and there can be two edge electrodes 13. The end of the branch electrode 12 on one side of the main electrode 11 that is away from the main electrode 11 is connected to an edge electrode 13.

[0062] Optionally, such as Figures 2 to 5 As shown, in two adjacent sub-pixels 1a in the first direction D1, the distance s1 between the two close branch electrodes 12 of the two sub-pixels 1a in the first direction D1 is greater than or equal to the distance s2 between the two adjacent branch electrodes 12 in the same sub-pixel 1a in the first direction D1.

[0063] In some embodiments, such as Figures 2 to 5 As shown, in two adjacent sub-pixels 1a in the first direction D1, the distance s1 between the two close branch electrodes 12 of the two sub-pixels 1a in the first direction D1 is equal to the distance s2 between two adjacent branch electrodes 12 in the same sub-pixel 1a in the first direction D1. Through this arrangement, the electric field of the region between two adjacent pixel electrodes 10 can be made close to the electric field of the region of pixel electrode 10, thereby making the light transmittance of the region between two adjacent pixel electrodes 10 in the first direction D1 close to the light transmittance of the liquid crystal molecules in the region of pixel electrode 10.

[0064] In some embodiments, such as Figures 2 to 5 As shown, in two adjacent sub-pixels 1a in the first direction D1, the distance s1 between the two close branch electrodes 12 of the two sub-pixels 1a in the first direction D1 is greater than the distance s2 between two adjacent branch electrodes 12 in the same sub-pixel 1a in the first direction D1. This setting reduces the manufacturing difficulty of the pixel electrode 10.

[0065] Optionally, such as Figures 2 to 5 As shown, at least one branch electrode 12 extends beyond the main electrode 11 in the first direction D1. This means that at least one branch electrode 12, at its end furthest from the main electrode 11, is not flush with the main electrode 11 and extends in the first direction D1 away from the main electrode 11. With this arrangement, at least one branch electrode 12 can be brought closer to the branch electrode 12 of another adjacent sub-pixel 1a, thereby making the electric field between the two closely spaced branch electrodes 12 close to the electric field between two adjacent branch electrodes 12 of the same sub-pixel 1a, and making the light transmittance of the region between two adjacent pixel electrodes 10 in the first direction D1 closer to the light transmittance of the liquid crystal molecules in the region of the pixel electrode 10.

[0066] like Figures 2 to 5As shown, the branch electrode 12 at the right edge of the pixel electrode 10 extends beyond the main electrode 11 and toward the other pixel electrode 10 on the right.

[0067] In some embodiments, such as Figure 2 As shown, the branch electrode 12 at the right edge of the pixel electrode 10 extends beyond the main electrode 11 and beyond the edge of the main electrode 11 of the other sub-pixel 1a on the right. With the above arrangement, the branch electrode 12 can be made closer to the branch electrode 12 of the other sub-pixel 1a, reducing the width of the area between two adjacent sub-pixels 1a in the first direction D1, and reducing the width of the black lines.

[0068] In some embodiments, such as Figure 2 As shown, the distance by which the branch electrode 12 extends beyond the main electrode 11 in the first direction D1 is the first distance s3.

[0069] Optionally, such as Figures 2 to 5 As shown, in two adjacent sub-pixels 1a in the first direction D1, the distance s4 between the two main electrodes 11 is smaller than the distance s1 between the two closely spaced branch electrodes 12 of the two sub-pixels 1a in the first direction D1. With this arrangement, the main electrodes 11 can be extended, thereby making the electric field of the region between the two adjacent pixel electrodes 10 in the first direction D1 closer to the electric field of the pixel electrode 10 region, and thus making the light transmittance of the region between the two adjacent pixel electrodes 10 in the first direction D1 closer to the light transmittance of the liquid crystal molecules in the pixel electrode 10 region.

[0070] In some embodiments, in two adjacent sub-pixels 1a in the first direction D1, the spacing s4 between the two main electrodes 11 is 2 micrometers to 6 micrometers. For example, in two adjacent sub-pixels 1a s4 in the first direction D1, the spacing s4 between the two main electrodes 11 is 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, 6 micrometers, etc.

[0071] It should be noted that, Figures 3 to 5 The numbers s1, s2, s3, and s4 are not labeled. Please refer to [the original text] for their meanings. Figure 2 The annotations in the text.

[0072] Optionally, such as Figures 2 to 5 As shown, the display panel 1 also includes a light-shielding portion 40 disposed on the side of the pixel electrode 10 near the light-emitting surface of the display panel 1. The light-shielding portion 40 is disposed between two adjacent pixel electrodes 10 along the second direction D2, and the area between two adjacent pixel electrodes 10 along the first direction D1 does not overlap with the light-shielding portion 40.

[0073] In some embodiments, the display panel 1 further includes a light-shielding portion 40, which is made of a material with light-shielding capabilities. For example, the light-shielding portion 40 may be made of a black material.

[0074] In some embodiments, such as Figures 2 to 5 As shown, the light-shielding portion 40 is disposed between two adjacent pixel electrodes 10 along the second direction D2, and the area between two adjacent pixel electrodes 10 along the first direction D1 does not overlap with the light-shielding portion 40. That is to say, the light-shielding portion 40 is only disposed between two adjacent pixel electrodes 10 along the second direction D2, and not between two adjacent pixel electrodes 10 along the first direction D1. This arrangement can improve the black lines on the second direction D2.

[0075] According to the second aspect of this application, such as Figure 1 and Figure 6 As shown, a display panel 1 is provided, including a plurality of sub-pixels 1a arranged along a first direction D1 and a second direction D2. The second direction D2 intersects the first direction D1. The display panel 1 includes pixel electrodes 10 and a common electrode layer 20 disposed in different layers. One pixel electrode 10 corresponds to one sub-pixel 1a, and the common electrode layer 20 corresponds to a plurality of sub-pixels 1a. The common electrode layer 20 is provided with a plurality of hollow patterns 21 arranged along the first direction D1. The pixel electrodes 10 overlap with the hollow patterns 21. The area between two adjacent pixel electrodes 10 along the first direction D1 is a first area A1, and the first area A1 overlaps with the hollow patterns 21.

[0076] In some embodiments, the display panel 1 may be a liquid crystal display (LCD) panel, etc. For example, the display panel 1 may be a fringe field switching (FFS) type panel. When the display panel 1 is an FFS type panel, the pixel electrode 10 and the common electrode layer 20 may be disposed on the same side of the liquid crystal layer.

[0077] In some embodiments, the common electrode layer 20 is disposed on the side of the pixel electrode 10 near the liquid crystal layer.

[0078] In other embodiments, the common electrode layer 20 is disposed on the side of the pixel electrode 10 away from the liquid crystal layer.

[0079] In some embodiments, such as Figure 6 As shown, one pixel electrode 10 corresponds to one sub-pixel 1a, and the common electrode layer 20 corresponds to multiple sub-pixels 1a. This means that the pixel electrodes 10 of two adjacent sub-pixels 1a are not continuous, but the common electrode layers 20 of two adjacent sub-pixels 1a can be continuous.

[0080] In some embodiments, such as Figure 6As shown, the pixel electrode 10 can be a block electrode, that is, the pixel electrode 10 may not have a main electrode 11 or a branch electrode 12, but may be in the shape of a block.

[0081] In some embodiments, such as Figure 6 As shown, the common electrode layer 20 is provided with a plurality of hollow patterns 21 arranged along the first direction D1. The pixel electrode 10 overlaps with the hollow pattern 21. The area between two adjacent pixel electrodes 10 along the first direction D1 is the first area A1, and the first area A1 overlaps with the hollow pattern 21.

[0082] The cutout pattern 21 refers to the pattern formed after removing material from a portion of the common electrode layer 20. In the cutout pattern 21, no material from the common electrode layer 20 is present. The cutout pattern 21 overlaps not only with the pixel electrode 10 but also with the first region A1. Through this arrangement, the electric fields of the first region A1 and the corresponding regions of the pixel electrode 10 can be made closer, thereby improving the light transmittance of the liquid crystal molecules in the first region A1 and improving the black lines between two adjacent sub-pixels 1a in the first direction D1.

[0083] In some embodiments, sub-pixel 1a can be a single-domain, double-domain, quad-domain, or octet structure. A single-domain structure refers to the liquid crystal molecules of sub-pixel 1a deflecting in a single direction in an electric field. A double-domain structure refers to the liquid crystal molecules of sub-pixel 1a deflecting in two directions in an electric field. A quad-domain structure refers to the liquid crystal molecules of sub-pixel 1a deflecting in four directions in an electric field. An octet structure refers to the liquid crystal molecules of sub-pixel 1a deflecting in eight directions in an electric field. By changing the extension direction of the cutout pattern 21, sub-pixel 1a can form single-domain, double-domain, quad-domain, or octet structures. For example, the cutout pattern 21 in sub-pixel 1a can be extended in a single direction to form a single domain. This application does not limit the number of extension directions of the cutout pattern 21.

[0084] Optionally, such as Figure 6 As shown, a portion of the same cutout pattern 21 overlaps with the pixel electrode 10, and another portion of the same cutout pattern 21 overlaps with the first region A1. This arrangement allows for a more seamless transition between the region corresponding to the pixel electrode 10 and the first region A1, thereby increasing the light transmittance of the liquid crystal molecules in the first region A1 and improving black lines.

[0085] Optionally, such as Figure 6 As shown, the outline of the hollow pattern 21 is not parallel to the outline of the first region A1; wherein, two adjacent hollow patterns 21 overlap with the same first region A1.

[0086] In some embodiments, such as Figure 6As shown, the outline of the cutout pattern 21 is not parallel to the outline of the first region A1, which makes it easier for a part of the cutout pattern 21 to overlap with the pixel electrode 10, and for another part of the cutout pattern 21 to overlap with the first region A1.

[0087] In some embodiments, such as Figure 6 As shown, two adjacent cutout patterns 21 overlap with the same first region A1. This means that each of two adjacent cutout patterns 21 partially overlaps with the first region A1. This arrangement increases the number of cutout patterns 21 in the first region A1, resulting in a finer electric field distribution in the first region A1, which is closer to the electric field of the region corresponding to the pixel electrode 10, thus reducing the difference in light transmittance between the first region A1 and the region corresponding to the pixel electrode 10.

[0088] Optionally, such as Figure 6 As shown, the shapes of two adjacent hollow patterns 21 in the first direction D1 are the same; and / or, the spacing s6 of two adjacent hollow patterns 21 in the first direction D1 is the same.

[0089] In some embodiments, such as Figure 6 As shown, the two adjacent cutout patterns 21 in the first direction D1 have the same shape, which means that the two adjacent cutout patterns 21 in the first direction D1 can completely overlap after being moved.

[0090] In some embodiments, such as Figure 6 As shown, the spacing s6 between two adjacent cutout patterns 21 in the first direction D1 is the same. With the above setting, the cutout patterns 21 can be arranged at equal intervals, so that the spacing between the area corresponding to the pixel electrode 10 and the cutout pattern 21 in the first area A1 is consistent, thereby reducing the difference in light transmittance between the area corresponding to the pixel electrode 10 and the first area A1.

[0091] In some embodiments, such as Figure 6 As shown, the two adjacent cutout patterns 21 in the first direction D1 have the same shape, and the spacing s6 between the two adjacent cutout patterns 21 in the first direction D1 is the same. Through the above arrangement, the difference in light transmittance between the area corresponding to the pixel electrode 10 and the first area A1 can be further reduced.

[0092] Optionally, such as Figure 6 As shown, the first region A1 and the hollow pattern 21 have an overlapping part 30. In two adjacent first regions A1, the patterns of the two overlapping parts 30 are different. Figure 6 The overlapping portion 30 is shown in the area where the section lines are not filled.

[0093] In some embodiments, such as Figure 6As shown, the overlapping part 30 refers to the pattern formed by the overlapping area of ​​the first region A1 and the hollow pattern 21. The overlapping part 30 is the intersection of the first region A1 and the hollow pattern 21.

[0094] In some embodiments, such as Figure 6 As shown, in two adjacent first regions A1, the patterns of the two overlapping portions 30 are different. Since the width of the pixel electrode 10 in the first direction D1 and the width s7 of the first region A1 in the first direction D1 are different, when the cutout pattern 21 is arranged along the first direction D1, the portion overlapping with each first region A1 will be different, thus forming overlapping portions 30 with different patterns. Through the above arrangement, the requirements for the shape of the cutout pattern 21, etc., can be reduced, and the precision requirements for the manufacturing process of the display panel 1 can also be reduced.

[0095] Optionally, such as Figure 6 As shown, the hollow pattern 21 includes a main body 211 and edge portions 212 disposed at both ends of the main body 211. The extension length of the main body 211 is greater than the extension length of the edge portions 212. The main body 211 extends along a third direction D3, and the third direction D3 forms an acute angle with the first direction D1.

[0096] In some embodiments, such as Figure 6 As shown, the cutout pattern 21 includes a main body 211 and an edge 212. The main body 211 extends along a third direction D3, which forms an acute angle with the first direction D1. With the above arrangement, the extension direction of the main body 211 can be different from the extension direction of the outline of the first region A1, thereby making it easier for the main body 211 to overlap with the first region A1.

[0097] Optionally, such as Figure 6 As shown, the extending direction of the edge portion 212 is different from the extending direction of the main body portion 211, and / or, the extending directions of the two edge portions 212 in the same hollow pattern 21 are the same.

[0098] In some embodiments, such as Figure 6 As shown, the extending direction of the edge portion 212 is different from the extending direction of the main body portion 211. This arrangement allows the deflection direction of the liquid crystal molecules in the region corresponding to the edge portion 212 to differ from the deflection direction of the liquid crystal molecules in the region corresponding to the main body portion 211, thereby expanding the viewing angle of the display panel 1.

[0099] In some embodiments, such as Figure 6 As shown, the two edge portions 212 in the same hollow pattern 21 extend in the same direction. With the above arrangement, the edge portions 212 of two adjacent sub-pixels 1a in the second direction D2 can extend in the same direction, thereby improving the black lines between two adjacent sub-pixels 1a in the second direction D2.

[0100] In some embodiments, such as Figure 6 As shown, the extending direction of the edge portion 212 is different from the extending direction of the main body portion 211, and the extending directions of the two edge portions 212 in the same hollow pattern 21 are the same. With the above arrangement, the viewing angle of the display panel 1 can be expanded, while the black lines between two adjacent sub-pixels 1a in the second direction D2 can be improved.

[0101] Optionally, such as Figure 6 As shown, the width s5 of the hollow pattern 21 in the first direction D1 is smaller than the spacing s6 between two adjacent hollow patterns 21 in the first direction D1; and / or, the width s7 of the first region A1 in the first direction D1 is smaller than the spacing s6 between two adjacent hollow patterns 21 in the first direction D1.

[0102] In some embodiments, such as Figure 6 As shown, the width s5 of the hollow pattern 21 in the first direction D1 is smaller than the distance s6 between two adjacent hollow patterns 21 in the first direction D1.

[0103] In some embodiments, such as Figure 6 As shown, the width s7 of the first region A1 in the first direction D1 is smaller than the spacing s6 between two adjacent hollow patterns 21 in the first direction D1.

[0104] In some embodiments, such as Figure 6 As shown, the width s5 of the hollow pattern 21 in the first direction D1 is smaller than the distance s6 between two adjacent hollow patterns 21 in the first direction D1, and the width s7 of the first region A1 in the first direction D1 is smaller than the distance s6 between two adjacent hollow patterns 21 in the first direction D1.

[0105] Optionally, such as Figure 6 As shown, the display panel 1 also includes a light-shielding portion 40 disposed on the side of the pixel electrode 10 and the common electrode layer 20 near the light-emitting surface of the display panel 1. The light-shielding portion 40 is disposed between two adjacent pixel electrodes 10 along the second direction D2, and the first region A1 does not overlap with the light-shielding portion 40.

[0106] In some embodiments, such as Figure 6 As shown, the display panel 1 also includes a light-shielding portion 40 disposed on the side of the pixel electrode 10 and the common electrode layer 20 near the light-emitting surface of the display panel 1. That is to say, the light-shielding portion 40 is located on the side of the pixel electrode 10 near the light-emitting surface of the display panel 1, and the light-shielding portion 40 is located on the side of the common electrode layer 20 near the light-emitting surface of the display panel 1.

[0107] In some embodiments, such as Figure 6As shown, the light-shielding portion 40 is disposed between two adjacent pixel electrodes 10 along the second direction D2, and the first region A1 does not overlap with the light-shielding portion 40. That is to say, the light-shielding portion 40 is only disposed between two adjacent pixel electrodes 10 along the second direction D2, and not between two adjacent pixel electrodes 10 along the first direction D1. This arrangement can improve the black lines on the second direction D2.

[0108] like Figure 7 As shown, Figure 7 This is a simulation data diagram of the light transmittance of the display panel 1 provided in the exemplary embodiment of this disclosure. Figure 7 In the diagram, the horizontal axis represents distance, corresponding to different positions of the pixel electrode 10, and the vertical axis represents the transmittance at different positions of the pixel electrode 10. The area enclosed by the dashed box is the region between two adjacent pixel electrodes 10 in the first direction D1. The left side of the dashed box represents the transmittance at different positions of one pixel electrode 10, and the right side represents the transmittance at different positions of the other pixel electrode 10. Figure 7 As can be seen, the embodiments of this application can improve the light transmittance of the area between two adjacent pixel electrodes 10 in the first direction D1, thereby improving black lines.

[0109] According to the third aspect of this application, such as Figure 8 As shown, a display terminal 2 is provided, including the display panel 1 described above.

[0110] In some embodiments, the display terminal 2 can be used for 3D display scenarios.

[0111] Optionally, such as Figure 8 As shown, the display terminal 2 also includes a lens layer 3 disposed on one side of the light-emitting surface of the display panel 1. The lens layer 3 includes a plurality of lens units 31, which extend along the fourth direction D4 and intersect with the first direction D1.

[0112] In some embodiments, the display terminal 2 further includes a lens layer 3 disposed on one side of the light-emitting surface of the display panel 1. The lens layer 3 is used to divide the image of the display panel 1 into an image for the left eye to view and an image for the right eye to view, thereby realizing stereoscopic display.

[0113] In some embodiments, such as Figure 8 As shown, the fourth direction D4 intersects the first direction D1, meaning the fourth direction D4 is not parallel to the first direction D1. For example, the fourth direction D4 can be perpendicular to the first direction D1, or it can be parallel to the second direction D2, but it is not limited to these.

[0114] In some embodiments, such as Figure 8As shown, the first direction D1 is the row direction of the display panel 1. Since the images for the left and right eyes are divided along the first direction D1 when the display panel 1 displays an image, when black lines appear between two adjacent sub-pixels 1a on the first direction D1, it causes light crosstalk between the left and right eye images, affecting the stereoscopic display effect. Therefore, in the display panel 1, by increasing the light transmittance of the area between two adjacent pixel electrodes 10 on the first direction D1, black lines between two adjacent pixel electrodes 10 on the first direction D1 are avoided, thereby improving the stereoscopic display effect.

[0115] In some embodiments, the display terminal 2 can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0116] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0117] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0118] The embodiments, implementation methods, and related technical features of this application can be combined and substituted for each other without conflict.

[0119] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of the technical solution of this application.
