It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
An embodiment of the present invention provides a display panel, as shown in fig. 1, fig. 2 and fig. 3, fig. 1 is a first top view of an array substrate provided in an embodiment of the present invention, fig. 2 is a first top view of a color film substrate provided in an embodiment of the present invention, and fig. 3 is a first cross-sectional view of the display panel provided in an embodiment of the present invention, that is, fig. 3 is a first cross-sectional view along a direction a-a' of the display panel including the array substrate 1 shown in fig. 1 and the color film substrate 2 shown in fig. 2; the display panel comprises an array substrate 1 and a color film substrate 2 which are oppositely arranged, and the display panel also comprises a liquid crystal layer 3 arranged between the array substrate 1 and the color film substrate 2; the array substrate 1 includes a plurality of gate lines 11 and a plurality of data lines 12 which are arranged in a staggered manner, and touch traces 13 which are arranged above a part of the data lines 12 in a direction perpendicular to the array substrate 1, the gate lines 11, the data lines 12 and the touch traces 13 are arranged in an insulated manner, in order to clearly show the relative positions of the gate lines 11, the data lines 12 and the touch traces 13, an insulating layer for insulating the gate lines 11, the data lines 12 and the touch traces 13 is not shown in fig. 1, and other subsequent figures are also processed correspondingly; the color film substrate 2 comprises a black matrix 21, the black matrix 21 comprises a first black matrix 21a corresponding to the gate line 11 and a second black matrix 21b corresponding to the data line 12, and a main spacer 22 is arranged above a part of intersection position of the first black matrix 21a and the second black matrix 21b in a direction perpendicular to the color film substrate 2; the touch trace 13 includes a main structure 131 only located above the data line 12, and a connection structure 132 located above the crossing position of the gate line 11 and the data line 12, where the connection structure 132 corresponding to the position of the main spacer 22 is a first connection structure 132a, and the first connection structure 132a at least partially surrounds one end of the main spacer 22 contacting the array substrate 1.
In the display panel with the above structure, one end of the main spacer 22 contacting the array substrate 1 can stably contact the array substrate 1, so that the main spacer 22 can be disposed on the portion of the second black matrix 21b corresponding to the touch trace 13, and thus the number of the main spacers 22 on the color filter substrate 2 can be increased, and the strength of the display panel can be improved. In addition, in the display panel with the above structure, since the number of the touch leads 13 does not affect the number of the main spacers 22 on the color film substrate 2, the number of the touch leads 13 disposed on the array substrate 1 can be increased, and thus one touch electrode can correspond to a plurality of touch leads 13, that is, the plurality of touch leads 13 are connected in parallel to provide a touch signal for one touch electrode, so that loss of the touch signal in the process of transmitting the touch signal to the touch electrode can be effectively reduced. In addition, in the prior art, the end of the main spacer in contact with the array substrate is easy to move, in order to shield the main spacer well, the area of the black matrix is large, and the transmittance of the display panel is not high, but in the embodiment of the invention, because the end of the main spacer 22 in contact with the array substrate 1 is limited by the first connecting structure 132a, the main spacer can be stably in contact with the array substrate 1 and is not easy to move, so that the area of the black matrix 21 can be smaller than that of the black matrix in the prior art, and compared with the prior art, the aperture ratio of the display panel is improved.
Note that, the above-mentioned "the first connecting structure 132a at least partially surrounds one end of the main spacer 22 contacting the array substrate 1" is: as shown in fig. 1 and fig. 3, each of the first connecting structures 132a completely surrounds one end of the main spacer 22 contacting the array substrate 1, or, as shown in fig. 4 and fig. 5, fig. 4 is a second top view of the array substrate provided in the embodiment of the present invention, and fig. 5 is a second cross-sectional view of the display panel provided in the embodiment of the present invention, that is, fig. 5 is a schematic cross-sectional view of the display panel including the array substrate 1 shown in fig. 4 along the direction a-a', each of the first connecting structures 132a partially surrounds one end of the main spacer 22 contacting the array substrate 1, or a part of the first connecting structures 132a partially surrounds one end of the main spacer 22 contacting the array substrate 1, and another part of the first connecting structures 132a completely surrounds one end of the main spacer 22 contacting the array substrate 1.
In an example, as shown in fig. 1 and fig. 3, each of the first connection structures 132a completely surrounds one end of the main spacer 22 contacting the array substrate 1, and at this time, when the array substrate 1 and/or the color filter substrate 2 are stressed in a direction parallel to the array substrate 1, because one end of the main spacer 22 contacting the array substrate 1 is limited by the first connection structure 132a in each direction parallel to the array substrate 1, the array substrate 1 and the color filter substrate 2 cannot move relative to each other, which is beneficial to maintaining structural stability of the display panel and ensuring display effect of the display panel.
In this example, the first connecting structures 132a may surround the end of the main spacer 22 contacting the array substrate 1: for example, first, the shape of the cross section of the first connecting structure 132a does not match the shape of the end of the main spacer 22 contacting the array substrate 1, but has a size larger than that of the end of the main spacer 22 contacting the array substrate 1, and the end of the main spacer 22 contacting the array substrate 1 can be placed in the space surrounded by the first connecting structure 132 a; secondly, as shown in fig. 1 and 3, the cross-sectional shape and size of the first connecting structure 132a match with the shape and size of the end of the main spacer 22 contacting the array substrate 1, and the end of the main spacer 22 contacting the array substrate 1 can be placed in the space surrounded by the first connecting structure 132 a.
In the second implementation manner, the first connecting structure 132a has a good effect of limiting the position of the end of the main spacer 22 contacting the array substrate 1, and the first connecting structure 132a has a large width and is not prone to disconnection, so in the embodiment of the present invention, preferably, as shown in fig. 1, the cross-sectional shape and size of the first connecting structure 132a are matched with the shape and size of the end of the main spacer 22 contacting the array substrate 1. For example, if the end of the main spacer 22 contacting the array substrate 1 has a circular shape and a diameter of 5 μm to 10 μm, the cross-sectional shape of the first connecting structure 132a is also circular and has a diameter slightly larger than that of the end of the main spacer 22 contacting the array substrate 1, and the slightly larger range is suitable for just placing the end of the main spacer 22 contacting the array substrate 1, for example, the cross-sectional diameter of the first connecting structure 132a is 5.5 μm to 10.5 μm.
It should be added that, the shape of the end of the main spacer 22 contacting the array substrate 1 may be various, for example, circular, oval, rectangular or rhombic, and correspondingly, the cross-sectional shape of the first connecting structure 132a may also be various, for example, circular, oval, rectangular or rhombic, and the like, that is, the first connecting structure 132a is a circular frame as shown in fig. 1, an oval frame as shown in fig. 6, a rectangular frame as shown in fig. 7 or a rhombic frame as shown in fig. 8, and fig. 6 to 8 are three to five top views of the array substrate provided by the embodiment of the present invention. When the first connection structure 132a is an oval frame, a circular frame, a rectangular frame, or a diamond frame, if the width of the frame is large, the overall size of the first connection structure 132a is large, in order to sufficiently shield the first connection structure 132a, the width of the second black matrix 21b on the color film substrate 2 in the extending direction of the gate line 11 is large, so that the aperture ratio of the display panel is not high, and if the width of the frame is small, the touch trace 13 is easy to break, and the resistance is large, so that it is very important to reasonably select the width of the frame of the first connection structure 132a, optionally, the width of the frame of the first connection structure 132a in the embodiment of the present invention is 1 μm to 4 μm.
In another example, as shown in fig. 4 and 5, each of the first connection structures 132a semi-surrounds one end of the main spacer 22 contacting the array substrate 1. At this time, when the array substrate 1 and/or the color filter substrate 2 are stressed in a direction parallel to the array substrate 1, the first connection structure 132a does not have an ideal limiting effect on the end of the main spacer 22 in contact with the array substrate 1, so that the array substrate 1 and the color filter substrate 2 are likely to move relatively.
In order to improve the limiting effect of the first connecting structures 132a on the end of the array substrate 1 contacting the main spacers 22, in an embodiment of the invention, as shown in fig. 9, fig. 9 is a top view of the array substrate according to an embodiment of the invention, in the extending direction of the data lines 12, every x rows of the first connecting structures 132a is a group of first connecting structures 132a, in any two adjacent groups of the first connecting structures 132a, the opening of one group of the first connecting structures 132a faces the first side, the opening of the other group of the first connecting structures 132a faces the second side, the first side and the second side are two sides oppositely disposed in the extending direction of the gate lines 11, and x is a positive integer greater than or equal to 1, so that in any two adjacent groups of the first connecting structures 132a, one group of the first connecting structures 132a can limit the end of the main spacers 22 contacting the array substrate 1 to move to the second side, the other group of first connecting structures 132a may limit the end of the main spacer 22 corresponding thereto, which is in contact with the array substrate 1, to move toward the first side, so as to reduce the possibility of relative movement between the array substrate 1 and the color film substrate 2, which is beneficial to maintaining the structural stability of the display panel and ensuring the display effect of the display panel. For example, in fig. 9, a row of the first connecting structures 132a is a group of the first connecting structures 132a, and any two adjacent groups of the first connecting structures 132a, such as the first row of the first connecting structures 132a and the second row of the first connecting structures 132a, have openings of the first row of the first connecting structures 132a facing a first side (e.g., left side) and openings of the second row of the first connecting structures 132a facing a second side (e.g., right side).
Optionally, the display panel in the embodiment of the present invention is a pseudo dual domain display panel, as shown in fig. 10, fig. 10 is a top view of an array substrate provided in the embodiment of the present invention, a plurality of gate lines 11 and a plurality of data lines 12 on the array substrate 1 are alternately disposed to define a plurality of pixel regions, a pixel electrode 14 is disposed in each pixel region, a slit 141 is disposed on the pixel electrode 14, an extending direction of the slit 141 and an extending direction of the gate line 11 form an included angle α, and the included angle α is an acute angle, wherein, in the extending direction of the data line 12, each y row of pixel electrodes 14 is a group of pixel electrodes 14, the slits 141 of one group of pixel electrodes 14 are symmetrical to the slits 141 of another group of pixel electrodes 14 adjacent thereto along the extending direction of the gate line 11, and y is a positive integer greater than or equal to 1.
Based on this structure, in the embodiment of the present invention, the number x of rows of the first connection structures 132a included in the group of first connection structures 132a is selected to be equal to the number y of rows of the pixel electrodes 14 included in the group of pixel electrodes 14, that is, the first connection structures 132a corresponding to the group of pixel electrodes 14 are the group of first connection structures 132a, so that the structure of the first connection structures 132a can be matched with the structure of the data line 12 below the first connection structures 132a, for example, the protruding portion of the first connection structure 132a corresponding to the turning position of the data line 12 protruding toward the left side also faces toward the left side, and the opening faces the right side, so that the width of the second black matrix 21b on the color film substrate 2 does not need to be too large to shield the touch leads 13, which is beneficial to improving the aperture ratio of the display panel. In this embodiment, if the pixel electrodes 14 in more rows are a group of pixel electrodes 14, the improvement effect on the viewing angle and the display effect is not good, so that the value of y is 1, 2, 3, 4, or 5, and correspondingly, the value of x is 1, 2, 3, 4, or 5.
Similarly, in this example, the first connecting structures 132a may be implemented to half-surround the end of the main spacer 22 contacting the array substrate 1 in various ways: for example, first, the shape of the cross section of the first connecting structure 132a does not match the shape of the half of the end of the main spacer 22 contacting the array substrate 1, but has a size larger than the half of the end of the main spacer 22 contacting the array substrate 1, and the half of the end of the main spacer 22 contacting the array substrate 1 can be placed in the space surrounded by the first connecting structure 132 a; secondly, the cross-sectional shape and size of the first connecting structure 132a match with the shape and size of the half of the end of the main spacer 22 contacting the array substrate 1, and the half of the end of the main spacer 22 contacting the array substrate 1 can be placed in the space surrounded by the first connecting structure 132 a.
In the second implementation manner, the first connection structure 132a has a better effect of limiting the position of the end of the main spacer 22 contacting the array substrate 1, and the first connection structure 132a has a larger width and is not easy to break, so in the embodiment of the present invention, the cross-sectional shape and size of the first connection structure 132a are preferably matched with the shape and size of half of the end of the main spacer 22 contacting the array substrate 1. For example, the end of the main spacer 22 contacting the array substrate 1 is circular and has a diameter of 5 μm to 10 μm, and the cross-sectional shape of the first connecting structure 132a is semicircular and has a diameter slightly larger than that of the end of the main spacer 22 contacting the array substrate 1, wherein the slightly larger range is suitable for just placing half of the end of the main spacer 22 contacting the array substrate 1, for example, the cross-sectional diameter of the first connecting structure 132a is 5.5 μm to 10.5 μm.
It should be added that the shape of the end of the main spacer 22 contacting the array substrate 1 may be various, such as a circle, an ellipse, a rectangle or a diamond, and correspondingly, the cross-sectional shape of the first connecting structure 132a may also be various, such as a semicircle, a semi-ellipse, a rectangle or a triangle, and so on, i.e. the first connecting structure 132a is a semi-ellipse frame, a semi-circle frame, a rectangle frame or a triangle frame. Similarly, when the first connection structure 132a is a semi-elliptical frame, a semicircular frame, a rectangular frame, or a triangular frame, if the width of the frame is large, the overall size of the first connection structure 132a is large, and in order to fully shield the first connection structure 132a, the width of the second black matrix 21b on the color film substrate 2 in the extending direction of the gate line 11 is large, which results in a low aperture ratio of the display panel, and if the width of the frame is small, the touch trace 13 is easy to break, and the resistance is large, so it is very important to reasonably select the width of the frame of the first connection structure 132a, and optionally, the width of the frame of the first connection structure 132a in the embodiment of the present invention is 1 μm to 4 μm.
In addition, the inventor of the present application finds that if only the main spacer 22 exists in the display panel, when a large pressure is applied to the color film substrate 2 and the array substrate 1, vacuum bubbles are easily generated, a gravity failure is easily generated during the use process, and when the color film substrate 2 and the array substrate 1 change in thickness due to an external force, the color film substrate 2 and the array substrate 1 recover slowly. In order to solve the above problem, as shown in fig. 2 and fig. 3, in an embodiment of the present invention, in a direction perpendicular to the color filter substrate 2, an auxiliary spacer 23 is disposed above an intersection position of the first black matrix 21a and the second black matrix 21b where the main spacer 22 is not disposed, and a height of the auxiliary spacer 23 is smaller than a height of the main spacer 22. Correspondingly, as shown in fig. 1 and fig. 3, the connection structure 132 corresponding to the position of the auxiliary spacer 23 is a second connection structure 132b, and the second connection structure 132b at least partially surrounds the orthographic projection of the auxiliary spacer 23 on the array substrate 1.
Note that, the "orthographic projection of the second connecting structure 132b at least partially surrounding the auxiliary spacer 23 on the array substrate 1" is: as shown in fig. 1 and 3, each of the second connecting structures 132b completely surrounds the orthographic projection of the auxiliary spacers 23 on the array substrate 1, or, as shown in fig. 4 and 5, each of the second connecting structures 132b half surrounds the orthographic projection of the auxiliary spacers 23 on the array substrate 1, or, a part of the second connecting structures 132b half surrounds the orthographic projection of the auxiliary spacers 23 on the array substrate 1, and another part of the second connecting structures 132b completely surrounds the orthographic projection of the auxiliary spacers 23 on the array substrate 1.
With respect to the shape and size of the second connecting structure 132b, the present embodiment provides three alternative ways: first, as shown in fig. 1 and 4, the second connection structure 132b has the same shape and size as the first connection structure 132a, and since the first connection structure 132a has a shape and size sufficient to fully surround or half surround the end of the main spacer 22 contacting the array substrate 1, the second connection structure 132b having the same shape and size as the first connection structure 132a is also necessarily sufficient to fully surround or half surround the orthographic projection of the auxiliary spacer 23 on the array substrate 1; secondly, the second connecting structure 132b completely surrounds the orthographic projection of the auxiliary spacer 23 on the array substrate 1, and the cross-sectional shape and size of the second connecting structure 132b are matched with the shape and size of the orthographic projection of the auxiliary spacer 23 on the array substrate 1; thirdly, the second connecting structure 132b semi-surrounds the orthographic projection of the auxiliary spacer 23 on the array substrate 1, and the shape and size of the cross section of the second connecting structure 132b are matched with the shape and size of the half of the orthographic projection of the auxiliary spacer 23 on the array substrate 1.
The specific details of the second and third arrangement manners may be set with reference to the specific details of "the first connecting structure 132a completely surrounds the end of the main spacer 22 contacting the array substrate 1" and "the first connecting structure 132a partially surrounds the end of the main spacer 22 contacting the array substrate 1", and only the relevant parameter "of the end of the main spacer 22 contacting the array substrate 1" needs to be replaced by the relevant parameter "of the orthogonal projection of the auxiliary spacer 23 on the array substrate 1", and the "first connecting structure 132 a" needs to be replaced by the "second connecting structure 132 b", which is not described herein again.
