Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] As people have higher and higher requirements for the cost and thinness of display screens, some thicker film layers have to be removed to make the display panel meet certain cost and thickness requirements, such as the planarization layer on the array substrate.

[0003] The planarization layer on the array substrate is used to planarize the thin-film transistors or signal wiring. The surface of the array substrate is uneven due to the patterning of the relevant film layer. When the planarization layer is deleted, the surface of the array substrate in the signal wiring area is convex, and the surface of the signal wiring area is relatively concave, and the signal wiring area is relatively small. The signal wiring line width is small, so the area of ​​the protruding area is also relatively small. In order to prevent the signal wiring from reflecting light, the display panel usually sets a black matrix above the signal wiring for shading, and usually sets the support column for supporting the display panel in the area where the signal wiring is located. Because the liquid crystal molecules around the support column are easily squeezed to produce light leakage, this design can simultaneously use the black matrix located above the signal wiring to shield the area where the support column is located, thereby minimizing the area shielded by the black matrix and increasing the light emitting area of ​​the display panel. If the area of ​​the protruding area where the signal routing is located is too large, the support column and the protruding area of ​​the signal routing will be displaced when the display panel is impacted by external force, so that the support column and the protruding area of ​​the signal routing cannot be aligned with each other, resulting in insufficient supporting force for the display panel, and further making the thickness of the liquid crystal layer formed at different positions between the array substrate and the opposing substrate uneven. Light passing through liquid crystal layers of different thicknesses will form different optical path differences, thereby affecting the uniformity of light output and possibly causing light leakage; even if the display panel is not impacted by external force, due to the alignment deviation between the signal routing and the support column itself, the relative position relationship between the support columns and the signal routing in different areas is inconsistent, that is, the support columns in some areas may be aligned with the protruding areas of the signal routing, while the support columns in some areas may slip and fail to support the protruding areas of the signal routing, which will also cause insufficient supporting force for the display panel and affect the uniformity of light output.

[0004] Therefore, how to achieve good support for the display panel of the de-planarization layer while ensuring that the display panel has a relatively high light output area, that is, to ensure its aperture ratio and achieve a higher brightness display, is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, embodiments of the present invention provide a display panel and a display device, which can provide good support for the display panel and ensure that the display panel has high brightness.

[0006] In a first aspect, the present invention provides a display panel, comprising:

[0007] An array substrate and a color filter substrate are arranged opposite to each other, and a support column located between the array substrate and the color filter substrate, wherein the support column comprises a main support column, wherein the main support column is arranged on one side of the array substrate or the color filter substrate and abuts against the surface of the other side of the substrate opposite to the array substrate, and the main support column comprises a first support column;

[0008] The display panel includes a plurality of sub-pixel units arranged in an array, a scan line extending along a first direction and a data line extending along a second direction, the first direction and the second direction intersect, wherein the sub-pixel unit is formed by the intersection of the scan line and the data line, the sub-pixel unit includes a thin film transistor, the thin film transistor includes a gate, a source and a drain, the scan line is electrically connected to the gate of the thin film transistor, the data line is electrically connected to the source of the thin film transistor, the sub-pixel unit also includes a pixel electrode, and the pixel electrode is electrically connected to the drain of the thin film transistor;

[0009] Along the first direction, the projection of the first support column in the direction perpendicular to the plane where the display panel is located is located between the projections of two adjacent data lines in the direction perpendicular to the plane where the display panel is located. Along the second direction, the projection of the first support column in the direction perpendicular to the plane where the display panel is located is located on one side of the projection of the scanning line in the direction perpendicular to the plane where the display panel is located.

[0010] In a second aspect, the present invention further provides a display device, which includes the display panel described in the first aspect.

[0011] The display panel provided by the present invention arranges the main support columns of a part of the area between two data lines along the first direction and on one side of the scanning line along the second direction, that is, avoids the area where the scanning line and the data line are located. On the one hand, it can avoid the main support columns from contacting the protruding area where the data line and the scanning line are located, that is, the main support columns can abut on a relatively flat surface to form a good support for the display panel, avoiding display abnormalities due to poor support when the display panel is impacted by external force; on the other hand, the main support columns can be arranged close to the scanning line. Usually, the width of the black matrix of the display panel arranged along the extension direction of the scanning line is larger than the width of the black matrix arranged along the extension direction of the data line. Therefore, the main support columns are arranged close to the scanning line, and the black matrix above the scanning line can be fully utilized for shielding, thereby avoiding light leakage caused by liquid crystal disturbance around the main support columns, thereby ensuring normal display of the display panel, and at the same time reducing the shielding area of ​​the black matrix to ensure high-brightness display of the display panel.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] At present, the demand for thinner display panels is getting higher and higher, and the cost of display panels is constantly decreasing. These two factors have led to the continuous thinning and reduction of the film layers of display panels. Driven by thinness and cost, it may be necessary to delete the planarization layer on the array substrate, which will result in the film surface being uneven after the signal lines and driving elements in the display panel are patterned, that is, the area where the metal layer is set on the array substrate is thicker than the area where the metal layer is not set. Figures 1-2 As shown, Figure 1 A partial top view of a display panel provided for an existing design, Figure 2 for Figure 1 A schematic cross-sectional view along the section line A-A'; Figure 1 A plurality of sub-pixel unit regions P are shown in the figure. The sub-pixel unit region P is formed by the intersection of the scan line s and the data line d. The support column includes a main support column mps and an auxiliary support column sps. The main support column mps plays a major supporting role. Figure 2 As shown, Figure 2The display panel includes an array substrate 01 and a color film substrate 02. One end of the main support column mps is arranged on one side of the color film substrate 02, and the other end is abutted against one side of the array substrate 01 to support the display panel. The array substrate 01 includes at least one metal layer. The scanning line s is located on the first metal layer m1, and the data line d is located on the second metal layer m2. The array substrate 01 does not have a flat layer. The area where the scanning line s and the data line d are located protrudes toward the side of the color film substrate 02 due to the height of the metal layer, especially the area where the scanning line s and the data line d overlap, where the protrusion height is the largest. In the direction perpendicular to the plane where the display panel is located, the projection of the main support column mps is parallel to the scanning line s. The area overlapping with the data line d overlaps, and the surface area of ​​the main support column mps abutting against the side of the array substrate 01 is much larger than the line width of the scanning line s and the data line d, so that the surface of the main support column mps is not completely occupied on the plane, and some areas are in an unsupported state. When the display panel is impacted by external force, it is easy to tilt or slide to the lower thickness position of the array substrate 01, thereby resulting in insufficient support for the display panel, and further resulting in uneven thickness of the liquid crystal layer formed at different positions between the array substrate 01 and the color film substrate 02. Different optical path differences will be formed when light passes through liquid crystal layers of different thicknesses, thereby affecting the uniformity of light output and may cause light leakage.

[0048] The inventors of the present application have found that even if the main support column mps is set to avoid the overlapping position of the scan line s and the data line d, that is, the main support column mps only overlaps with the scan line s or only overlaps with the data line d, the above-mentioned problem still exists, and the inventors have further found that if the standing position of the main support column mps is not moved, one of the solutions can make the main support column mps stand on a relatively flat surface by increasing the line width of the scan line s and / or the data line d at the position of the main support column mps corresponding to the scan line s and / or the data line d, but this solution will increase the parasitic capacitance between the scan line s and the data line d, which is not conducive to charging the pixel unit on the display panel; or, another solution can make the scan line s and / or the data line d be wound at the standing position of the main support column mps, and the main support column mps can also be made to stand on a relatively flat surface, but this solution is not conducive to the wiring of the display panel and will sacrifice a larger light-transmitting area, thereby affecting the brightness of the display panel.

[0049] Based on the above problems, an embodiment of the present invention provides a display panel, such as Figures 3 to 5 As shown, Figure 3 A schematic top view of a display panel provided by an embodiment of the present invention, Figure 4 for Figure 3 A schematic diagram showing the S region of the panel, Figure 5 for Figure 4A cross-sectional schematic diagram along the section line B-B'; the display panel 1 includes an array substrate 10 and a color film substrate 20 that are relatively arranged, and a support column PS located between the array substrate 10 and the color film substrate 20, the support column PS includes a main support column MPS, the main support column MPS is arranged on one side of the color film substrate 20 and abuts against the array substrate 10, optionally, in other embodiments of the present invention, the main support column MPS may also be arranged on one side of the array substrate 10 and abut against the color film substrate 20.

[0050] The display panel 1 includes a plurality of sub-pixel units P1 arranged in an array, a scan line SL extending along a first direction X and a data line DL extending along a second direction Y, the first direction X and the second direction Y intersect, and the sub-pixel unit P1 is formed by the scan line SL and the data line DL intersecting, and optionally, Figure 4 As shown, the extension direction of the sub-pixel unit P1 includes Y1 and Y2, wherein the sub-pixel unit P1 includes a pixel electrode PL ( Figure 4 The pixel electrode PL also extends in directions Y1 and Y2, and the data line DL also extends in directions Y1 and Y2, wherein Y1, Y2 and the first direction X intersect with each other, that is, the sub-pixel unit P1 is a dual-domain sub-pixel unit; optionally, in other embodiments of the present invention, the sub-pixel unit P1 may also be a single-domain sub-pixel unit, or a multi-domain sub-pixel unit greater than the dual-domain, that is, the pixel electrode extends in a single direction or in a non-single direction, which are all included in the embodiments of the present invention; the sub-pixel unit P1 includes a thin film transistor T( Figure 4 The thin film transistor T further comprises a gate electrode, a source electrode and a drain electrode DE, wherein the scan line SL is electrically connected to the gate electrode, the data line DL is electrically connected to the source electrode, and the pixel electrode PL is electrically connected to the drain electrode DE.

[0051] The main support column MPS in the display panel 1 includes a first support column PS1. Along the first direction X, the projection of the first support column PS1 in the direction perpendicular to the plane where the display panel 1 is located is located between the projections of two adjacent data lines DL in the direction perpendicular to the plane where the display panel 1 is located. Along the second direction Y, the projection of the first support column PS1 in the direction perpendicular to the plane where the display panel 1 is located is located on one side of the projection of the scan line SL in the direction perpendicular to the plane where the display panel 1 is located, that is, the first support column PS1 is set in the area surrounded by the two adjacent data lines DL and the scan line SL, and is set close to the scan line SL. Optionally, the first support column PS1 can overlap with the drain electrode DE which is also located in the area surrounded by the two adjacent data lines DL and the scan line SL. At this time, the projection area of ​​the drain electrode DE can be appropriately increased, so that the surface of the abutting area of ​​the first support column PS1 is relatively flat; optionally, the first support column PS1 may not overlap with the drain electrode DE, and the surface of the abutting area of ​​the first support column PS1 can also be relatively flat.

[0052] The display panel 1 provided by the present invention arranges the main support column MPS of a part of the area between two data lines DL along the first direction X and on one side of the scanning line SL along the second direction Y, that is, avoids the area where the scanning line SL and the data line DL are located. On the one hand, it can avoid the main support column MPS from contacting the protruding area where the data line DL and the scanning line SL are located, that is, the main support column MPS can abut on a relatively flat surface to form a good support for the display panel 1, and avoid the display abnormality caused by poor support when the display panel 1 is impacted by external force; on the other hand, the main support column MPS can be arranged close to the scanning line SL. Usually, the width of the black matrix of the display panel 1 arranged along the first direction X is greater than the width of the black matrix arranged in the extension direction of the second direction Y. Therefore, the main support column MPS is arranged close to the scanning line SL, and the black matrix above the scanning line SL can be fully utilized for shielding, thereby avoiding light leakage caused by liquid crystal disturbance around the main support column MPS, thereby ensuring the normal display of the display panel 1, and at the same time reducing the shielding area of ​​the black matrix to ensure the high-brightness display of the display panel 1.

[0053] Optional, continue to refer to Figures 3-4 The support column PS also includes an auxiliary support column SPS. In the direction perpendicular to the plane where the display panel 1 is located, the height of the main support column MPS is greater than the height of the auxiliary support column SPS, that is, the auxiliary support column SPS mainly plays an auxiliary supporting role. When the display panel 1 is not impacted by an external force, the auxiliary support column SPS does not contact the opposite substrate. Only when the display panel 1 is impacted by an external force, such as when an external force is pressed, it may abut against the opposite substrate. Optionally, at least part of the auxiliary support column SPS is also arranged in the area surrounded by two adjacent data lines DL and the scanning line SL, and is close to the scanning line SL, that is, the main support column MPS and the auxiliary support column SPS both include a first support column PS1, and the first support column PS1 is at The position of the sub-pixel unit P1 is consistent; on the one hand, when the display panel 1 is pressed by an external force, the auxiliary support column SPS can come into contact with the opposite substrate, and the contact plane can also be relatively flat, thereby avoiding the auxiliary support column SPS of the display panel 1 from tilting and shifting, thereby enhancing the supporting capacity of the display panel 1; on the other hand, the main support column MPS and the auxiliary support column SPS are arranged at the same position as the sub-pixel unit P1, so that the centers of the black matrix above the main support column MPS and the auxiliary support column SPS are approximately on the same horizontal line, which is also convenient for setting a narrower black matrix to block the support column PS, thereby maximizing the light transmittance of the display panel 1 and further realizing high-brightness display of the display panel 1.

[0054] Optional, see Figure 3 and Figure 6 , Figure 6 for Figure 3Another schematic diagram of the display panel S area; the sub-pixel unit P1 includes a first sub-pixel unit P11 and a second sub-pixel unit P12, wherein in a first direction X, the first sub-pixel unit P11 and the second sub-pixel unit P12 are adjacently arranged, and in a direction perpendicular to the plane where the display panel 1 is located, a projection of a data line DL electrically connected to the second sub-pixel unit P12 is included between the projection of the drain DE of the first sub-pixel unit P11 and the projection of the drain DE of the second sub-pixel unit P12, that is, along the first direction X, the drain DE of the first sub-pixel unit P11, the data line DL electrically connected to the second sub-pixel unit P12, and the drain DE of the second sub-pixel unit P12 are arranged in sequence.

[0055] Furthermore, in the direction perpendicular to the display panel 1, the first support column PS1 may be arranged to overlap with the projection of the first sub-pixel unit P11, and the projection of the first support column PS1 may be located between the projection of the drain DE of the first sub-pixel unit P11 and the projection of the data line DL electrically connected to the second sub-pixel unit P12, that is, the first support column PS1 is supported between the projection of the drain DE of the first sub-pixel unit P11 and the projection of the data line DL electrically connected to the second sub-pixel unit P12; optionally, the first support column PS1 may include a main support column MPS and an auxiliary support column SPS. On the one hand, by placing the supporting position of the first support column PS1 between the projection of the drain DE of the first sub-pixel unit P11 and the projection of the data line DL electrically connected to the second sub-pixel unit P12, the first support column PS1 can be blocked to a certain extent in the first direction X by means of the protrusions at the positions of the drain DE and the data line DL, thereby limiting the sliding of the first support column PS1. On the other hand, the first support column PS1 can avoid the setting of the drain DE, avoid the influence of the via hole electrically connecting the pixel electrode PL and the drain DE on the support of the first support column PS1, and further ensure the flatness of the supporting surface of the first support column PS1, thereby ensuring the supporting force of the display panel 1 and avoiding display abnormalities due to poor support when the display panel 1 is impacted by external force.

[0056] Optional, continue to refer to Figure 6In the direction perpendicular to the plane where the display panel 1 is located, the distance between the projection of the data line DL electrically connected to the first sub-pixel unit P11 and the projection of the drain electrode DE in the first direction X is L1, and the distance between the projection of the drain electrode DE corresponding to the first sub-pixel unit P11 and the projection of the data line DL electrically connected to the second sub-pixel unit P12 in the first direction X is L2, wherein L1<L2, by compressing the setting distance between the data line DL and the drain electrode DE corresponding to the first sub-pixel unit P11 along the first direction X, thereby making room for the supporting position of the first supporting column PS1, facilitating the setting of the first supporting column PS1, so that the first sub-pixel unit P11 has sufficient space for accommodating the embedding of the first supporting column PS1, thereby effectively ensuring the supporting force of the display panel 1, and avoiding display abnormality due to poor support when the display panel 1 is impacted by external force.

[0057] Furthermore, L1 is set to be greater than or equal to 2.8 μm, that is, in the first direction X, the distance between the projection of the data line DL electrically connected to the first sub-pixel unit P11 and the projection of the drain electrode DE is greater than or equal to 2.8 μm. On the one hand, it can ensure that no short circuit occurs between the data line DL and the drain electrode DE of the first sub-pixel unit P11, and on the other hand, the parasitic capacitance between the data line DL and the drain electrode DE of the first sub-pixel unit P11 is within a reasonable range, thereby avoiding abnormal display of the first sub-pixel unit P11 and further ensuring the uniformity of display of the display panel 1.

[0058] Optional, please continue to refer to Figure 6 The sub-pixel unit P1 includes a third sub-pixel unit P13. In a direction perpendicular to the plane where the display panel 1 is located, the third sub-pixel unit P13 is a sub-pixel unit P1 whose projection does not overlap with the first support column PS1. The distance between the data line DL and the drain electrode DE electrically connected to the third sub-pixel unit P13 and projected in the first direction X is D1, and D1>L1 can be set, that is, in the sub-pixel unit P1 without the first support column PS1, the setting distance between the corresponding data line DL and the drain electrode DE along the first direction X is not compressed, so that the setting distance between the two is greater than the setting distance between the two in the sub-pixel unit P1 with the first support column PS1. Under the condition that the display difference between the first sub-pixel unit P11 and the third sub-pixel unit P13 is not easily noticeable, the process difficulty of the sub-pixel unit P1 without the first support column PS1 can be reduced.

[0059] Optional, see Figure 7 , Figure 7 for Figure 3Another schematic diagram of the display panel S area; any sub-pixel unit P1 included in the display panel 1 can be set, in the direction perpendicular to the plane where the display panel 1 is located, the distance W1 between the projection of the corresponding electrically connected data line DL and the projection of the drain DE in the first direction X is smaller than the distance W2 between the projection of the corresponding drain DE and the projection of the corresponding electrically connected data line DL of the adjacent sub-pixel unit P1 in the first direction X, that is, W1<W2; that is, regardless of whether the first support column PS1 is set, the setting distance between the data line DL and the drain DE corresponding to any sub-pixel unit P1 along the first direction X is compressed, thereby ensuring the consistency of the setting between each sub-pixel unit P1, which is beneficial to the uniform display of the display panel 1.

[0060] Optional, see Figure 3 and Figure 8 , Figure 8 for Figure 3 Another schematic diagram of the display panel S area; further, in the direction perpendicular to the display panel 1, the first support column PS1 can be arranged to overlap with the projection of the first sub-pixel unit P11, and the projection of the first support column PS1 is located between the projection of the drain DE of the first sub-pixel unit P11 and the projection of the data line DL electrically connected to it, that is, the first support column PS1 is supported between the projection of the drain DE of the first sub-pixel unit P11 and the projection of the data line DL electrically connected to the first sub-pixel unit P11; optionally, the first support column PS1 may include a main support column MPS and an auxiliary support column SPS. On the one hand, by placing the supporting position of the first support column PS1 between the projection of the data line DL electrically connected to the first sub-pixel unit P11 and its corresponding projection of the drain electrode DE, the first support column PS1 can be blocked to a certain extent in the first direction X by means of the protrusions at the positions of the drain electrode DE and the data line DL, thereby limiting the sliding of the first support column PS1. On the other hand, the first support column PS1 can avoid the setting of the drain electrode DE, avoid the influence of the via hole electrically connecting the pixel electrode PL and the drain electrode DE on the support of the first support column PS1, and further ensure the flatness of the supporting surface of the first support column PS1, thereby ensuring the supporting force of the display panel 1, and avoiding display abnormalities due to poor support when the display panel 1 is impacted by external force.

[0061] Optional, continue to refer to Figure 8In the direction perpendicular to the plane where the display panel 1 is located, the distance between the projection of the data line DL electrically connected to the first sub-pixel unit P11 and the projection of the drain electrode DE in the first direction X is L3, and the distance between the projection of the drain electrode DE corresponding to the first sub-pixel unit P11 and the projection of the data line DL electrically connected to the second sub-pixel unit P12 in the first direction X is L4, wherein L3>L4, by extending the setting distance between the data line DL and the drain electrode DE corresponding to the first sub-pixel unit P11 along the first direction X, and compressing the setting distance between the drain electrode DE corresponding to the first sub-pixel unit P11 and the data line DL electrically connected to the second sub-pixel unit P12 along the first direction X, space is made for the supporting position of the first supporting column PS1, which is convenient for the setting of the first supporting column PS1, so that the first sub-pixel unit P11 has sufficient space for accommodating the embedding of the first supporting column PS1, thereby effectively ensuring the supporting force of the display panel 1, and avoiding display abnormality due to poor support when the display panel 1 is impacted by external force.

[0062] Furthermore, L4 is set to be greater than or equal to 2.8μm, that is, in the first direction X, the distance between the projection of the drain DE corresponding to the first sub-pixel unit P11 and the projection of the data line DL electrically connected to the second sub-pixel unit P12 is greater than or equal to 2.8μm. On the one hand, it can ensure that there is no short circuit between the data line DL corresponding to the second sub-pixel unit P12 and the drain DE of the first sub-pixel unit P11, and on the other hand, the parasitic capacitance between the data line DL corresponding to the second sub-pixel unit P12 and the drain DE of the first sub-pixel unit P11 is within a reasonable range, thereby avoiding abnormal display of the second sub-pixel unit P12 and further ensuring the uniformity of display of the display panel 1.

[0063] Optional, please continue to refer to Figure 8, the sub-pixel unit P1 includes a third sub-pixel unit P13. In the direction perpendicular to the plane where the display panel 1 is located, the third sub-pixel unit P13 is a sub-pixel unit P1 that does not overlap with the first support column PS1 in projection. Then, the projection distance between the data line DL and the drain electrode DE electrically connected to the third sub-pixel unit P13 in the first direction X is D2, and D2<L3 can be set, that is, in the third sub-pixel unit P13, the setting distance between the corresponding data line DL and the drain electrode DE along the first direction X is not extended, and the corresponding drain electrode DE and the data line D electrically connected to the adjacent sub-pixel unit P1 are not compressed. L along the first direction X, so that the setting distance between the corresponding data line DL and the drain DE in the third sub-pixel unit P13 is smaller than the setting distance between the two in the first sub-pixel unit P11, so that the distance between the drain DE corresponding to the third sub-pixel unit P13 and the data line DL electrically connected to the adjacent sub-pixel unit P1 along the first direction X is relatively large, and under the condition that the display difference between the first sub-pixel unit P11 and the third sub-pixel unit P13 is not easy to be noticed, the process difficulty between the third sub-pixel unit P13 and the adjacent sub-pixel unit P1 can be reduced.

[0064] Optional, see Fig. 9 , Fig. 9 for Figure 3 Another schematic diagram of the display panel S area; any sub-pixel unit P1 included in the display panel 1 can be set, in the direction perpendicular to the plane where the display panel 1 is located, the distance W3 between the projection of the corresponding electrically connected data line DL and the projection of the drain DE in the first direction X is greater than the distance W4 between the projection of the corresponding drain DE and the projection of the corresponding electrically connected data line DL of the adjacent sub-pixel unit P1 in the first direction X, that is, W3>W4; that is, regardless of whether the first support column PS1 is set, the setting distance between the data line DL and the drain DE corresponding to any sub-pixel unit P1 along the first direction X is extended, thereby ensuring the consistency of the setting between each sub-pixel unit P1, which is beneficial to the uniform display of the display panel 1.

[0065] Optional, see Fig.10 , Fig.11 , Fig.14 and Fig.15 , Fig.10 for Figure 3 Another schematic diagram showing the S region of the panel, Fig.11 for Figure 3 Another schematic diagram showing the S region of the panel, Fig.14 for Fig.10 A schematic cross-sectional view along the section line C-C', Fig.15 for Fig.11A schematic cross-sectional view along the section line D-D'; in the first support column PS1, in the direction perpendicular to the plane where the display panel 1 is located, the projection of the main support column MPS can be set not to overlap with the projection of the pixel electrode PL, and the projection of the auxiliary support column SPS can overlap with the projection of the pixel electrode PL. On the one hand, the projection of the main support column MPS is set not to overlap with the projection of the pixel electrode PL. In the display panel 1, the main support column MPS plays a major supporting role. Therefore, compared with the auxiliary support column SPS, the main support column MPS needs to be supported on a flatter area. In order to enable the display panel 1 to obtain a stronger driving electric field, the pixel electrode PL usually includes multiple branches, especially in the FFS (Fringe Field In the fringe field switching driving mode, an electric field that drives the liquid crystal to rotate is generated between the pixel electrode PL and the common electrode of the entire surface. The pixel electrode PL has multiple branches, and each branch can generate an effective fringe electric field, so that the display panel 1 has a stronger driving electric field. Because the line width of a single branch of the pixel electrode PL is smaller than the supporting surface area of ​​the main support column MPS, if the main support column MPS contacts the branch of the pixel electrode PL, it is equivalent to that the main support column MPS may span multiple pixel electrode PL branches. Therefore, the projection of the main support column MPS is not overlapped with the projection of the pixel electrode PL, that is, the main support column MPS does not overlap with the projection of the pixel electrode PL with multiple branches. Then, the main support column MPS can be supported on a flatter film layer, thereby effectively ensuring the supporting performance of the display panel 1. On the other hand, it is set The projection of the auxiliary support column SPS overlaps with the projection of the pixel electrode PL. In the display panel 1, the auxiliary support column SPS mainly plays an auxiliary supporting role, that is, when the display panel 1 is not subjected to external force, the auxiliary support column SPS does not contact the opposite substrate. Usually, the area density of the auxiliary support column SPS is greater than the area density of the main support column MPS, that is, the number of sub-pixel units P1 with the auxiliary support column SPS is greater than the number of sub-pixel units P1 with the main support column MPS. The larger the area of ​​the pixel electrode PL in the sub-pixel unit P1, the stronger the electric field generated. Therefore, for a large number of sub-pixel units P1 with the auxiliary support column SPS, the projection of the auxiliary support column SPS is set to overlap with the projection of the pixel electrode PL, so that the area of ​​the pixel electrode PL of the display panel 1 can be maximized, thereby ensuring that the display panel 1 has a higher display brightness.

[0066] Optional, see Fig.12 and Fig.13 , Fig.12 for Figure 3 Another schematic diagram showing the S region of the panel, Fig.13 for Figure 3Another schematic diagram of the display panel S area; the sub-pixel unit P1 includes a first sub-pixel unit P11, and the first sub-pixel unit P11 includes a first A sub-pixel unit P11A and a first B sub-pixel unit P11B. In order to increase the area density of the auxiliary support column SPS in the first support column PS1, the auxiliary support column SPS can be set in the first A sub-pixel unit P11A and the first B sub-pixel unit P11B, wherein in the direction perpendicular to the plane where the display panel 1 is located, the auxiliary support column SPS overlaps the projection area of ​​the pixel electrode PL in the first A sub-pixel unit P11A with a projection area of ​​S1, and overlaps the projection area of ​​the pixel electrode PL in the first B sub-pixel unit P11B with a projection area of ​​S2. The overlapping area of ​​the shadow is S2, then S1≠S2; because the display panel 1 usually includes a red sub-pixel unit, a green sub-pixel unit and a blue sub-pixel unit, when it is necessary to optimize the color display of the display panel 1, the pixel electrodes PL corresponding to the red sub-pixel unit, the green sub-pixel unit and the blue sub-pixel unit may be set inconsistently, thereby making the electric field strengths generated by the sub-pixel units of the three colors inconsistent, and optimizing the color matching of the display panel 1. When the auxiliary support columns SPS are located in sub-pixel units of different colors, the overlapping area between the auxiliary support columns SPS and the pixel electrodes PL of sub-pixel units of different colors may be different.

[0067] For further information, please refer to Fig.12 and Fig.13 , when the projection of the main support column MPS in the first main support column PS1 overlaps with the projection of the first sub-pixel unit P11A, S1<S2; since the projection of the main support column MPS and the pixel electrode PL in the first sub-pixel unit P11A do not overlap, the pixel electrode PL in the first sub-pixel unit P11A needs to avoid the main support column MPS for setting, which will inevitably lead to a reduction in the projection area of ​​the pixel electrode PL in the first sub-pixel unit P11A, and the main support column MPS is not set in the first sub-pixel unit P11B, so the projection area of ​​the pixel electrode PL in the first sub-pixel unit P11B is relatively large, then when the auxiliary support column SPS When the pixel electrodes PL in the first A sub-pixel unit P11A and the first B sub-pixel unit P11B overlap at the same time, the overlapping area S1 of the former will be smaller than the overlapping area S2 of the latter; this scheme occupies the auxiliary support column SPS and the main support column MPS in the same seed pixel unit P1, where the same seed pixel unit P1 refers to the consistent design of the pixel electrode PL. On the basis of ensuring that the main support column MPS does not overlap with the pixel electrode PL, the layout design can be simplified, that is, the pixel unit, which usually includes at least 3 sub-pixel units P1, can be arranged cyclically to ensure the uniform display of the display panel 1.

[0068] Optional, see Figures 16 to 18 , Fig.16A schematic top view of another display panel provided by an embodiment of the present invention, Fig.17 for Fig.16 A schematic diagram showing the area of ​​panel S', Fig.18 for Fig.16 Another schematic diagram of the display panel S' area; the display panel 2 also includes a touch electrode TE and a touch line TL, the touch line TL is electrically connected to the touch electrode TE, and the touch line TL and the data line DL can be located in the same metal layer; along the first direction X, the sub-pixel unit P1 includes a first sub-pixel unit P01 and a second sub-pixel unit P02 that are adjacent to each other, and a third sub-pixel unit P03 and a fourth sub-pixel unit P04 that are adjacent to each other. It should be noted that the present invention does not limit the arrangement relationship between the first sub-pixel unit P01, the second sub-pixel unit P02 and the third sub-pixel unit P03 and the fourth sub-pixel unit P04, that is, the first sub-pixel unit P01, the second sub-pixel unit P02, the third sub-pixel unit P03, and the fourth sub-pixel unit P04 can be arranged in sequence along the first direction X, or other sub-pixel units P1 are included between the first sub-pixel unit P01, the second sub-pixel unit P02 and the third sub-pixel unit P03 and the fourth sub-pixel unit P04, or as Fig.17 and Fig.18 As shown, the first sub-pixel unit P01 is also the fourth sub-pixel unit P04, that is, the first sub-pixel unit P01 and the fourth sub-pixel unit P04 are in a multiplexing relationship.

[0069] Along the first direction X, the drain DE of the first sub-pixel unit P01 and the drain DE of the second sub-pixel unit P02 include a data line DL electrically connected to the second sub-pixel unit P02, and the drain DE of the third sub-pixel unit P03 and the drain DE of the fourth sub-pixel unit P04 include not only the data line DL electrically connected to the fourth sub-pixel unit P04 but also the touch line TL; in the direction perpendicular to the plane where the display panel 2 is located, the projection of the main support column MPS in the first support column PS1 overlaps with the projection of the first sub-pixel unit P01, that is, along the first direction X, the main support column MPS is perpendicular to the plane where the display panel 2 is located. The projection in the direction is located between the projections of the data line DL electrically connected to the first sub-pixel unit P01 and the data line DL electrically connected to the second sub-pixel unit P02 in the direction perpendicular to the plane where the display panel 2 is located. Along the second direction Y, the projection of the main support column MPS in the direction perpendicular to the plane where the display panel 2 is located is located on one side of the projection of the scanning line SL of the first sub-pixel unit P01 in the direction perpendicular to the plane where the display panel 2 is located, that is, the main support column MPS is arranged in the area surrounded by two adjacent data lines DL and the scanning line SL, and is arranged close to the scanning line SL; further, the drain DE of the first sub-pixel unit 01 can be avoided. Since only the data line DL is included between the drain DE of the first sub-pixel unit P01 and the drain DE of the second sub-pixel unit P02, and the data line DL and the touch line TL are included between the drain DE of the third sub-pixel unit P03 and the drain DE of the fourth sub-pixel unit P04, when the touch line TL and the touch electrode TE are electrically connected through a through hole, there may also be a through hole on the touch line TL, that is, a through hole is also included between the drain DE of the third sub-pixel unit P03 and the drain DE of the fourth sub-pixel unit P04, which greatly compresses the support space occupied by the third sub-pixel unit P03 for the main support column MPS, and it is inconvenient to set the main support column MPS in the third sub-pixel unit P03; therefore, by setting the main support column MPS in the first sub-pixel unit P01, the space occupied by the sub-pixel unit P1 can be fully utilized, thereby ensuring the supporting capacity of the display panel 2. It should be noted that, as mentioned above, the arrangement position relationship between the second sub-pixel unit P02 and the third sub-pixel unit P03 is not limited, that is, it is not limited whether there is a touch line TL between the drain DE of the second sub-pixel unit P02 and the drain of the third sub-pixel unit P03. Therefore, when the touch line TL is not set between the two, the main support column MPS can also be set on the second sub-pixel unit P02, and when the touch line TL is set between the two, the main support column MPS is not set on the second sub-pixel unit P02.

[0070] Optionally, at least part of the auxiliary support columns SPS include a first main support column PS1, that is, at least part of the auxiliary support columns SPS are also arranged in the area surrounded by two adjacent data lines DL and the scan line SL, and are arranged close to the scan line SL; further, the drain DE of the first sub-pixel unit P01 can be avoided; that is, the main support column MPS and the auxiliary support column SPS are arranged at the same position of the sub-pixel unit P1, which is beneficial to reduce the blocking area of ​​the black matrix and ensure the high-brightness display of the display panel 2.

[0071] Optional, such as Fig.19 and Fig. 20 As shown, Fig.19 for Fig.16 Another schematic diagram showing the S' region of the panel, Fig. 20 for Fig.16 Another schematic diagram of the display panel S' area; the auxiliary support column SPS includes a first auxiliary support column SPS1 and a second auxiliary support column SPS2, wherein in the direction perpendicular to the plane where the display panel 2 is located, the projection area of ​​the first auxiliary support column SPS1 is larger than the projection area of ​​the second auxiliary support column SPS2, specifically, along the first direction X, the projection size of the first auxiliary support column SPS1 is larger than the projection size of the second auxiliary support column SPS; wherein the first auxiliary support column SPS1 can overlap with the projection of the first sub-pixel unit P01, and the second auxiliary support column SPS2 can overlap with the projection of the third sub-pixel unit P03; in order to further increase the auxiliary support The area density of the column SPS can be set, and the auxiliary support column SPS includes two types of auxiliary support columns SPS, wherein the auxiliary support column SPS with a larger projection area is set in the first sub-pixel unit P01, and the auxiliary support column SPS with a smaller projection area is set in the third sub-pixel unit P03, that is, the second auxiliary support column SPS compresses its size in the first direction X to reserve space for the electrical connection between the touch line TL and the touch electrode TE, while increasing the area density of the auxiliary support column SPS, thereby enhancing the ability of the display panel 2 to resist external forces, and also fully utilizing the occupied space in the sub-pixel unit P1, thereby ensuring the supporting capacity of the display panel 2.

[0072] Furthermore, an embodiment of the present invention provides a specific arrangement of sub-pixel units P1, such as Fig.21 and Fig. 22 As shown, Fig.21 for Fig.16 Another schematic diagram showing the S' region of the panel, Fig. 22 for Fig.16Another schematic diagram of the display panel S' area; the sub-pixel unit P1 includes a first sub-pixel unit PA, a second sub-pixel unit PB and a third sub-pixel unit PC, which are arranged adjacent to each other in sequence along the first direction X, and the three are arranged in a cycle; wherein, a data line DL electrically connected to the second sub-pixel unit PB is included between the drain DE of the first sub-pixel unit PA and the drain DE of the second sub-pixel unit PB, a data line DL electrically connected to the third sub-pixel unit PC is included between the drain DE of the second sub-pixel unit PB and the drain DE of the third sub-pixel unit PC, a data line DL electrically connected to the first sub-pixel unit PA and a touch line TL are included between the drain DE of the third sub-pixel unit PC and the drain DE of the first sub-pixel unit PA, and a touch line TL electrically connected to the first sub-pixel unit PA is included at a position vertical to the display panel 2. In the plane direction, the projection of the main support column MPS in the first support column PS1 may overlap with the projection of the first sub-pixel unit PA, or may overlap with the projection of the second sub-pixel unit PB, or may partially overlap with the projection of the first sub-pixel unit PA, and partially overlap with the projection of the second sub-pixel unit PB. Since a touch line TL is set between the third sub-pixel unit PC and the first sub-pixel unit PA, which may also have a through hole electrically connected to the touch electrode DE, it greatly occupies the space of the third sub-pixel unit PC for setting the main support column MPS. Therefore, overlapping the main support column MPS with the projection of the first sub-pixel unit PA and / or the second sub-pixel unit PB can make full use of the occupied space in the sub-pixel unit P1, thereby ensuring the supporting capacity of the display panel 2.

[0073] For further information, please refer to Fig.21 and Fig. 22, at least part of the auxiliary support columns SPS include a first main support column PS1, and the auxiliary support columns SPS include a first auxiliary support column SPS1 and a second auxiliary support column SPS2, wherein in the direction perpendicular to the plane where the display panel 2 is located, the projection area of ​​the first auxiliary support column SPS1 is larger than the projection area of ​​the second auxiliary support column SPS2, specifically, along the first direction X, the projection size of the first auxiliary support column SPS1 is larger than the projection size of the second auxiliary support column SPS; wherein the projection of the first auxiliary support column SPS1 may overlap with the projection of the first sub-pixel unit PA, or may overlap with the projection of the second sub-pixel unit PB, or may partially overlap with the projection of the first sub-pixel unit PA, partially overlap with the projection of the second sub-pixel unit PB, and the projection of the second auxiliary support column SPS2 overlaps with the projection of the third sub-pixel unit PC. In order to further increase the area density of the auxiliary support columns SPS, the auxiliary support columns SPS can be set to include two types of auxiliary support columns SPS, wherein the auxiliary support columns SPS with a larger projection area are arranged in the first sub-pixel unit PA and / or the second sub-pixel unit PB, and the auxiliary support columns SPS with a smaller projection area are arranged in the third sub-pixel unit PC, that is, the second auxiliary support columns SPS compress their dimensions in the first direction X to reserve space for electrical connection between the touch line TL and the touch electrode TE, while increasing the area density of the auxiliary support columns SPS, and also making full use of the space occupied in the sub-pixel unit P1, thereby ensuring the supporting capacity of the display panel 2.

The drain DE of the pixel unit P04 includes not only the data line DL electrically connected to the fourth sub-pixel unit P04, but also the touch line TL; in the direction perpendicular to the plane where the display panel 2 is located, the projection of the bridging layer M can be set between the projection of the drain DE of the third sub-pixel unit P03 and the projection of the data line DL electrically connected to the fourth sub-pixel unit P04. Further, when the auxiliary support column SPS of the display panel 2 includes the second auxiliary support column SPS2, the projection of the bridging layer M can be set between the projection of the second auxiliary support column SPS2 and the projection of the data line DL electrically connected to the fourth sub-pixel unit P04. By arranging the drain DE of the third sub-pixel unit P03, the second auxiliary support column SPS2, and the bridging layer M along the first direction X, on the one hand, the space of the sub-pixel unit P1 can be fully utilized, and on the other hand, the black matrix above the scanning line SL can be fully utilized for shielding, thereby relatively reducing the space covered by the black matrix and improving the transmittance of the display panel 2.

[0075] Optional, such as Fig.24 and Fig.26 As shown, Fig.24 for Fig.16 Another schematic diagram showing the S' region of the display panel, Fig.26 for Fig.16Another schematic diagram of the display panel S' region; based on another arrangement of the sub-pixel units P1 provided by the present invention, the sub-pixel unit P1 includes a first sub-pixel unit PA, a second sub-pixel unit PB and a third sub-pixel unit PC, which are arranged adjacent to each other in sequence along the first direction X, and the three are arranged cyclically; wherein, a data line DL electrically connected to the second sub-pixel unit PB is included between the drain DE of the first sub-pixel unit PA and the drain DE of the second sub-pixel unit PB, a data line DL electrically connected to the third sub-pixel unit PC is included between the drain DE of the second sub-pixel unit PB and the drain DE of the third sub-pixel unit PC, and a data line DL electrically connected to the first sub-pixel unit PA and a touch line TL are included between the drain DE of the third sub-pixel unit PC and the drain DE of the first sub-pixel unit PA; In the direction perpendicular to the plane where the display panel 2 is located, the projection of the bridging layer M can be set between the projection of the drain DE of the third sub-pixel unit PC and the projection of the data line DL electrically connected to the first sub-pixel unit PA. Further, when the auxiliary support column SPS of the display panel 2 includes the second auxiliary support column SPS2, the projection of the bridging layer M can be set between the projection of the second auxiliary support column SPS2 and the projection of the data line DL electrically connected to the first sub-pixel unit PA. By arranging the drain DE of the third sub-pixel unit P03, the second auxiliary support column SPS2, and the bridging layer M along the first direction X, on the one hand, the space of the sub-pixel unit P1 can be fully utilized, and on the other hand, the black matrix above the scanning line SL can be fully utilized for shielding, thereby relatively reducing the space covered by the black matrix and improving the transmittance of the display panel 2.

[0076] Optional, see Fig.25, in the direction perpendicular to the plane where the display panel 2 is located, when the projections of the first auxiliary support column SPS1 and the second auxiliary support column SPS2 are both arranged between the projection of the drain DE of the sub-pixel unit P1 and the projection of the data line DL electrically connected thereto, the distance between the projection of the drain DE corresponding to the third sub-pixel unit P03 and the projection of the data line DL electrically connected thereto of the sub-pixel unit P1 overlapping with the projection of the second auxiliary support column SPS2 is Q1 along the first direction X, and the distance between the projection of the drain DE corresponding to the first sub-pixel unit P01 and the projection of the data line DL electrically connected thereto of the sub-pixel unit P1 overlapping with the projection of the first auxiliary support column SPS1 is Q2 along the first direction X, wherein Q1<Q2; when the projections of the first auxiliary support column SPS1 and the second auxiliary support column SPS2 are both arranged between the projection of the drain DE of the sub-pixel unit P1 and the projection of the data line DL electrically connected thereto, the distance between the projection of the drain DE of the sub-pixel unit P1 and the projection of the data line DL electrically connected thereto of the sub-pixel unit P1 L needs to be expanded to facilitate the placement of the auxiliary support column SPS. Optionally, Q1 corresponding to the third sub-pixel unit P03 is set smaller than Q2 corresponding to the first sub-pixel unit P01. On the one hand, the supporting area of ​​the second auxiliary support column SPS2 is relatively small. According to the supporting area of ​​the second auxiliary support column SPS2, the distance between the drain DE corresponding to the third sub-pixel unit P03 and the data line DL is reasonably expanded, and the expanded distance is smaller than the distance between the drain DE corresponding to the first sub-pixel unit P01 and the data line DL, thereby increasing the distance between the drain DE of the third sub-pixel unit P03 and the touch line TL, which is convenient for process preparation; on the other hand, the expansion of the distance between the drain DE corresponding to the third sub-pixel unit P03 and the data line DL is reduced, and a preset space is left for the electrical connection method between the touch line TL and the touch electrode TE, such as through the setting of the bridging layer M, which is convenient for its reasonable placement.

[0077] Optional, such as Fig.24 and Fig.26As shown, in the direction perpendicular to the plane where the display panel 2 is located, in the first supporting column PS1, the projection of the main supporting column MPS does not overlap with the projection of the pixel electrode PL, and the auxiliary supporting column SPS includes a first auxiliary supporting column SPS1 and a second auxiliary supporting column SPS2, wherein the projection area of ​​the first auxiliary supporting column SPS1 is greater than the projection area of ​​the second auxiliary supporting column SPS2, so when the projection of the auxiliary supporting column SPS overlaps with the projection of the pixel electrode PL, there are at least two different overlapping areas, that is, the overlapping area of ​​the projection of the first auxiliary supporting column SPS1 and the pixel electrode PL is S3, and the overlapping area of ​​the projection of the second auxiliary supporting column SPS2 and the pixel electrode PL is S4, and S3 is not equal to S4;On the one hand, the projection of the main support column MPS is set not to overlap with the projection of the pixel electrode PL. The main support column MPS plays a major supporting role. Therefore, compared with the auxiliary support column SPS, the main support column MPS needs to be supported on a flatter area. In order to enable the display panel 2 to obtain a stronger driving electric field, the pixel electrode PL usually includes multiple branches, especially in the FFS (Fringe Field In the fringe field switching driving mode, an electric field for driving the rotation of the liquid crystal is generated between the pixel electrode PL and the common electrode of the entire surface. The pixel electrode PL has multiple branches, and each branch can generate an effective fringe electric field, so that the display panel 2 has a stronger driving electric field. Because the line width of a single branch of the pixel electrode PL is smaller than the supporting surface area of ​​the main support column MPS, if the main support column MPS contacts the branch of the pixel electrode PL, it is equivalent to that the main support column MPS may span multiple pixel electrode PL branches. Therefore, the projection of the main support column MPS is set not to overlap with the projection of the pixel electrode PL, that is, the main support column MPS does not overlap with the projection of the pixel electrode PL with multiple branches, then the main support column MPS can be supported on a flatter film layer, thereby effectively ensuring the supporting performance of the display panel 2. On the other hand, the projection of the auxiliary support column SPS is set to overlap with the projection of the pixel electrode PL. In the display panel 1, the auxiliary support column SPS mainly plays an auxiliary supporting role, that is, when the display panel 1 is not subjected to external force, the auxiliary support column SPS does not contact the opposite substrate, and usually the area density of the auxiliary support column SPS is greater than the area density of the main support column MPS. To ensure that the display panel 2 has good buffering and supporting capabilities when receiving external forces, the number of sub-pixel units P1 with auxiliary support columns SPS is greater than the number of sub-pixel units P1 with main support columns MPS. The larger the area of ​​the pixel electrode PL in the sub-pixel unit P1, the stronger the electric field generated. Therefore, for a large number of sub-pixel units P1 with auxiliary support columns SPS, the projection of the auxiliary support columns SPS is overlapped with the projection of the pixel electrode PL, which can maximize the area of ​​the pixel electrode PL of the display panel 2, thereby ensuring that the display panel 2 has a high display Brightness, further, the auxiliary support column SPS includes a first auxiliary support column SPS1 and a second auxiliary support column SPS2, thereby increasing the support area of ​​the auxiliary support column SPS, increasing the support capacity of the display panel 2, and the first auxiliary support column SPS1, the second auxiliary support column SPS2 and the pixel electrode PL have different overlapping areas. Since the first auxiliary support column SPS1 and the second auxiliary support column SPS2 have different area sizes, the station space of different sub-pixel units P1 can be fully utilized, and auxiliary support columns SPS of different area sizes can be matched, thereby achieving full utilization of the station space on the display panel 2. ;

[0078] Optional, continue to refer to Fig.24 and Fig.26, in the direction perpendicular to the plane where the display panel 2 is located, the first auxiliary support column SPS1 and the pixel electrode PL projection panel also include two types S31 and S32, S31 is not equal to S32; because the display panel 2 usually includes a red sub-pixel unit, a green sub-pixel unit and a blue sub-pixel unit, when it is necessary to optimize the color display of the display panel 2, it may cause the pixel electrodes PL corresponding to the red sub-pixel unit, the green sub-pixel unit and the blue sub-pixel unit to be set inconsistently, thereby making the electric field strengths generated by the sub-pixel units of the three colors inconsistent, and optimizing the color matching of the display panel 2. When the auxiliary support column SPS occupies sub-pixel units of different colors, it may cause the overlapping area between the auxiliary support column SPS and the pixel electrodes PL of the sub-pixel units of different colors to be different.

[0079] For further information, please refer to Fig.24 and Fig.26 When the projection of the main support column MPS in the first main support column PS1 overlaps with the projection of the sub-pixel unit P1, since the projection of the main support column MPS and the pixel electrode PL in the sub-pixel unit P1 do not overlap, the pixel electrode PL in the sub-pixel unit P1 needs to avoid the main support column MPS for setting, which will inevitably lead to a reduction in the projection area of ​​the pixel electrode PL in the sub-pixel unit P1. When the first auxiliary support column SPS1 overlaps with the pixel electrodes PL in two sub-pixel units P1 at the same time, one of them is consistent with the pixel electrode PL of the sub-pixel unit P1 where the main support column MPS is set, and the pixel electrode PL of this sub-pixel unit P1 needs to avoid the main support column MPS. Support column MPS, so the area of ​​pixel electrode PL is relatively reduced, so the first auxiliary support column SPS1 and the pixel electrode PL projection may also include two types S31 and S32, S31 is not equal to S32; this scheme is through the auxiliary support column SPS and the main support column MPS occupy the same seed pixel unit P1, where the same seed pixel unit P1 refers to the consistent design of the pixel electrode PL, on the basis of ensuring that the main support column MPS does not overlap with the pixel electrode PL, it can simplify the layout design, that is, ensure that the pixel unit, the pixel unit usually includes at least 3 sub-pixel units P1, can be arranged cyclically to ensure the uniform display of the display panel 2.

[0080] Optional, please continue to refer to Fig.24 and Fig.26The display panel 2 includes at least one metal layer, such as the first metal layer M1 where the scan line SL is located, and the second metal layer M2 where the data line DL and the touch line TL are located. Optionally, the display panel 2 may also include a shading metal layer (not shown in the figure), wherein the shading metal layer is used to block the channel of the thin film transistor to prevent it from being illuminated by backlight to generate carriers and cause leakage. Optionally, the display panel 2 may also include a third metal layer M3, etc. Then, in the direction perpendicular to the plane where the display panel 2 is located, the projection of the first support column PS1 is set to not overlap with the projection of any metal layer on the display panel 2, that is, the first support column PS1 not only does not overlap with the scan line SL, the data line DL and the touch line TL, but also does not overlap with other metal layers, thereby further ensuring that the first support column PS1 abuts against a flat surface, thereby forming a good support for the display panel 2, thereby avoiding display abnormalities due to poor support when the display panel 2 is impacted by external force.

[0081] Optional, such as Figures 28-30 As shown, Fig.28 for Fig.16 Another schematic diagram showing the S' region of the panel, Fig.29 for Fig.16 Another schematic diagram showing the S' region of the display panel, Fig.30 for Fig.16 Another schematic diagram of the display panel S' area; the display panel 2 includes a common electrode CM, and the common electrode CM has a hollow portion CMK. In the direction perpendicular to the plane where the display panel 2 is located, the hollow portion CMK overlaps with the projection of the drain DE of any sub-pixel unit P1, and the hollow portion CMK overlaps with the data line DL electrically connected to at least part of the sub-pixel unit P1. The color film substrate 20 includes a black matrix BM, wherein the projection of the black matrix BM covers the scan line SL, the data line DL and the touch line TL, and also covers the hollow portion CMK; the hollow portion CMK of the common electrode CM overlaps with the drain DE of the sub-pixel unit P1, and when the pixel electrode PL of the display panel 2 is located on the side of the common electrode CM away from the drain DE, the pixel electrode PL needs to be connected to the drain DE. In order to realize electrical connection, the common electrode CM is hollowed out to facilitate the overlap of the pixel electrode PL and the drain electrode DE, and to avoid short circuit between the pixel electrode PL and the common electrode CM; the hollow portion CMK of the common electrode CM overlaps with the data line DL of at least part of the sub-pixel unit P1, which can reduce the parasitic capacitance formed with the data line DL of at least part of the sub-pixel unit P1, thereby improving the charging capacity of the thin film transistor. However, because there is no common electrode CM in the area where the hollow portion CMK is located to shield the data line DL, in order to avoid the rotation of the liquid crystal above the data line DL when the data line DL is charged, thereby causing light leakage, a black matrix BM is required to block the hollow portion CMK to avoid light leakage and ensure the normal display of the display panel 2.

[0082] like Figures 28-29 As shown, the hollow portion CMK of the common electrode CM overlaps with the data line DL of a portion of the sub-pixel unit P1. Fig.30 As shown, the hollow portion CMK of the common electrode CM overlaps with the data line DL of any sub-pixel unit P1 , and this portion can be adjusted and set according to the position of the black matrix BM of the display panel 2 .

[0083] Optional, please continue to refer to Fig.28 Based on an arrangement mode of sub-pixel units P1 provided by the present invention, along a first direction X, the sub-pixel units P1 of the display panel 2 include adjacently arranged first sub-pixel units P01 and second sub-pixel units P02, and adjacently arranged third sub-pixel units P03 and fourth sub-pixel units P04; along the first direction X, a data line DL electrically connected to the second sub-pixel unit P02 is included between the drain DE of the first sub-pixel unit P01 and the drain DE of the second sub-pixel unit P02, and not only the data line DL electrically connected to the fourth sub-pixel unit P04 but also the touch line TL is included between the drain DE of the third sub-pixel unit P03 and the drain DE of the fourth sub-pixel unit P04; an auxiliary support column SP is provided. S includes a first auxiliary support column SPS1 and a second auxiliary support column SPS2. In the first support column PS1, in the direction perpendicular to the plane where the display panel 2 is located, the projection of the first auxiliary support column SPS1 is located between the projection of the drain DE of the first sub-pixel unit P01 and the projection of the data line DL electrically connected to the second sub-pixel unit P02, and the projection of the second auxiliary support column SPS2 is located between the projection of the drain DE of the third sub-pixel unit P03 and the projection of the data line DL electrically connected to the fourth sub-pixel unit P04. The projection of the hollow portion CMK does not overlap with the projection of the data line DL electrically connected to the fourth sub-pixel unit P04; that is, the hollow portion CMK is not arranged above the data line DL electrically connected to the fourth sub-pixel unit P04.

[0084] Because the drain DE of the third sub-pixel unit P03 and the drain DE of the fourth sub-pixel unit P04 include not only the data line DL electrically connected to the fourth sub-pixel unit P04, but also the touch line TL, the second auxiliary support column SPS2 is located between the drain DE of the third sub-pixel unit P03 and the touch line TL, and the supporting area of ​​the second auxiliary support column SPS2 is relatively small. In order to avoid the liquid crystal near the support column from being disturbed when pressed, thereby affecting the uniformity of the display panel 2, the area covered by the black matrix BM will expand outward from the area where the support column is located at the location of the support column, and the area of ​​the second auxiliary support column SPS is relatively small, so the outward expansion range of the black matrix BM is also small, and the second auxiliary support column SPS2 A touch line TL is also included between PS2 and the data line DL. If the common electrode CM above the data line DL is hollowed out, the outwardly expanded black matrix BM may not be able to completely cover the hollow portion CMK, that is, the hollow portion CMK may be partially unblocked, which will cause light leakage of the display panel 2 and lead to display abnormality. Therefore, in order to avoid display abnormality of the display panel 2, the hollow portion CMK is not set above the data line DL electrically connected to the fourth sub-pixel unit P04, so that the common electrode CM can be used to shield the electrical signal of the data line DL electrically connected to the fourth sub-pixel unit P04, and it can also ensure that the display panel 2 has a larger light-transmitting area, thereby ensuring the high-brightness display of the display panel 2.

[0085] Optional, such as Fig.30 As shown, the hollow portion CMK of the common electrode CM may be arranged to overlap with the data line DL of any sub-pixel unit P1. For the hollow portion CMK that cannot be covered by the outer expansion area of ​​the black matrix BM, for example, the width of the black matrix BM along the second direction Y may be appropriately increased, such as Fig.30 In the embodiment, the width h2 of the black matrix BM along the second direction Y is greater than Fig.28 In the figure, the width h1 of the black matrix BM along the second direction Y, the increased width of the black matrix BM can cover the hollow portion CMK, thereby ensuring the consistency of the charging capacity of any sub-pixel unit P1 of the display panel 2 and ensuring the uniformity of the display of the display panel 2.

[0086] Optional, such as Fig.31 and 32 As shown, Fig.31 for Fig.16 Another schematic diagram showing the S' region of the display panel, Fig.32 for Fig.16Another schematic diagram of the display panel S' area; based on another arrangement of sub-pixel units P1 provided by the present invention, the sub-pixel unit P1 includes a first sub-pixel unit PA, a second sub-pixel unit PB and a third sub-pixel unit PC, which are arranged adjacent to each other in sequence along a first direction X, and the three are arranged in a cycle; wherein a data line DL electrically connected to the second sub-pixel unit PB is included between the drain DE of the first sub-pixel unit PA and the drain DE of the second sub-pixel unit PB, a data line DL electrically connected to the third sub-pixel unit PC is included between the drain DE of the second sub-pixel unit PB and the drain DE of the third sub-pixel unit PC, and a data line DL electrically connected to the first sub-pixel unit PA and a touch line TL are included between the drain DE of the third sub-pixel unit PC and the drain DE of the first sub-pixel unit PA; an auxiliary support column SPS is provided, including a first auxiliary support Column SPS1 and the second auxiliary support column SPS2, in the first support column PS1, in the direction perpendicular to the plane where the display panel 2 is located, the projection of the first auxiliary support column SPS1 is located between the projection of the drain DE of the first sub-pixel unit PA and the projection of the data line DL electrically connected to the second sub-pixel unit PB, and / or the projection of the first auxiliary support column SPS1 is located between the projection of the drain DE of the second sub-pixel unit PB and the projection of the data line DL electrically connected to the third sub-pixel unit PC, and the projection of the second auxiliary support column SPS2 is located between the projection of the drain DE of the third sub-pixel unit PC and the projection of the data line DL electrically connected to the first sub-pixel unit PA, then the projection of the hollow portion CMK does not overlap with the projection of the data line DL electrically connected to the first sub-pixel unit PA; that is, the hollow portion CMK is not set above the data line DL electrically connected to the first sub-pixel unit PA.

[0087] Because the drain DE of the third sub-pixel unit PC and the drain DE of the first sub-pixel unit PA include not only the data line DL electrically connected to the first sub-pixel unit PA, but also the touch line TL, the second auxiliary support column SPS2 is located between the drain DE of the third sub-pixel unit PC and the touch line TL, and the supporting area of ​​the second auxiliary support column SPS2 is relatively small. In order to avoid the liquid crystal near the support column from being disturbed when pressed, thereby affecting the uniformity of the display panel 2, the area covered by the black matrix BM will be expanded outward from the area where the support column is located, and the area of ​​the second auxiliary support column SPS is relatively small, so the outward expansion range of the black matrix BM is also small, and the second auxiliary support column SPS A touch line TL is also included between S2 and the data line DL. If the common electrode CM above the data line DL is hollowed out, the outwardly expanded black matrix BM may not be able to completely cover the hollow portion CMK, that is, the hollow portion CMK may be in a partially unblocked state, which will cause light leakage of the display panel 2 and lead to display abnormality. Therefore, in order to avoid display abnormality of the display panel 2, the hollow portion CMK is not set above the data line DL electrically connected to the first sub-pixel unit PA, so that the common electrode CM can be used to shield the electrical signal of the data line DL electrically connected to the first sub-pixel unit PA, and it can also ensure that the display panel 2 has a larger light-transmitting area, thereby ensuring the high-brightness display of the display panel 2.

[0088] Optional, such as Fig.32 As shown, when in the direction perpendicular to the plane where the display panel 2 is located, the projection of the first auxiliary support column SPS1 is located between the projection of the drain DE of the first sub-pixel unit PA and the projection of the data line DL electrically connected to the first sub-pixel unit PA, and / or the projection of the first auxiliary support column SPS1 is located between the projection of the drain DE of the second sub-pixel unit PB and the projection of the data line DL electrically connected to the second sub-pixel unit PB, and the projection of the second auxiliary support column SPS2 is located between the projection of the drain DE of the third sub-pixel unit PC and the projection of the data line DL electrically connected to the third sub-pixel unit PC, then the projection of the hollow portion CMK may overlap with the projection of the data line DL electrically connected to the first sub-pixel unit PA, the second sub-pixel unit PB and the third sub-pixel unit PC, respectively; that is, the hollow portion CMK is arranged above the data lines DL corresponding to the first sub-pixel unit PA, the second sub-pixel unit PB and the third sub-pixel unit PC.

[0089] Because the first support columns PS1 are all arranged between the data line DL and the drain electrode DE of the corresponding sub-pixel unit P1, and are arranged close to the data line DL, when the black matrix BM is set at the position where the first support column PS1 is located for shielding, the area covered by the black matrix BM is expanded outward from the area where the first support column PS1 is located, and will cover part of the data line DL. Therefore, in this area, a hollow portion CMK is set for the common electrode CM, which can not only reduce the parasitic capacitance between the common electrode CM and the data line DL, thereby improving the charging capacity of the thin film transistor, but also use the black matrix BM that expands outward at the position where the first support column PS1 is located for shielding, thereby avoiding light leakage of the display panel 2, and ensuring that the display panel 2 has a larger light-transmitting area, thereby ensuring the high-brightness display of the display panel 2.
