Description

Display substrate, display panel, and display device Technical Field

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

[0002] With the development of display technology, the resolution of TV products is getting higher and higher, and the corresponding aperture ratio is gradually decreasing, but the demand for power consumption is becoming more and more urgent. This requires a significant increase in light extraction efficiency without increasing power consumption.

[0003] In existing product designs, spacers are used to maintain the stability and uniformity of the liquid crystal cell thickness and are typically cylindrical. Under external force, these cylindrical spacers can easily slide from the opaque area of ​​the array substrate to the translucent area. This process can scratch the alignment film, causing abnormal liquid crystal alignment. This can lead to display anomalies after the spacers have recovered.

[0004] The main solution at present is to design a larger light-shielding layer BM on the color filter substrate to shield the light, which causes the aperture ratio of the product to decrease, thereby reducing the light efficiency.

[0051] As shown in FIG1 to FIG4 , the present application provides a display substrate, which includes:

[0052] Array substrate 100 and color filter substrate 200;

[0053] A plurality of data lines 130 extending along a first direction F1 and a plurality of signal line groups 120 extending along a second direction F2 are provided on a side of the array substrate 100 close to the color filter substrate 200. The plurality of data lines 130 and the plurality of signal line groups 120 form a grid structure.

[0054] A plurality of strip-shaped spacers 320 are provided on one side of the color filter substrate 200 close to the array substrate 100 . The spacers 320 extend along the second direction F2 . The orthographic projections of the spacers 320 onto the array substrate 100 partially overlap with the signal line group 120 and the data lines 130 .

[0055] The present application utilizes the thickness of the signal line group and the data line itself in combination with the long strip spacers to form a structure that supports the thickness of the liquid crystal box. When the spacers are displaced, the support of the data lines and the signal line group can prevent the spacers from scratching the alignment film.

[0056] The following will describe in detail the various embodiments of the present application that are consistent with the above-mentioned creative concepts.

[0057] As shown in FIG. 1 to FIG. 5 , the present application provides a display substrate, which includes an array substrate 100 and a color filter substrate 200 .

[0058] The array substrate 100 includes a first substrate 110 and a driving circuit structure. The first substrate 110 can be a rigid substrate. The rigid substrate can be, for example, a glass substrate or a PMMA (Polymethyl methacrylate) substrate. The first substrate 110 can also be a flexible substrate. For example, the flexible substrate can be a PET (Polyethylene terephthalate) substrate, a PI (Polyimide) substrate, or a PEN (Polyethylene naphthalate two formic acid glycol ester) substrate. It is understandable that the first substrate 110 can be of various types and can be selected and set according to actual needs, and the embodiments of the present disclosure do not limit this.

[0059] A driving circuit structure is provided on the side of the substrate 110 adjacent to the color filter substrate 200. This driving circuit structure includes a plurality of data lines 130 extending along a first direction F1 and a plurality of signal line groups 120 extending along a second direction F2. The first direction F1 intersects the second direction F2, and the data lines 130 intersect the signal line groups 120. The data lines 130 and the signal line groups 120 form a grid structure. The grid structures define a plurality of pixel regions 400. Each grid structure corresponds to a pixel region 400, which can be a red pixel region, a green pixel region, or a blue pixel region. Each pixel region 400 is controlled by the data lines 130 and the signal line groups 120 located at its edges. Under the control of the signal line groups 120, the data lines 130 charge the liquid crystal capacitor Clc and the storage capacitor Cstg of the pixel region, thereby controlling the light emission of the pixel region 400. Optionally, the first direction F1 can be perpendicular to the second direction F2, meaning that the data lines 130 can be perpendicular to the signal line group 120, with the data lines 130 and the signal line group 120 forming a square grid structure. Alternatively, the data lines 130 can be arranged on the side of the signal line group 120 that is closer to the color filter substrate 200, or on the side of the signal line group 120 that is farther from the color filter substrate 200. An interlayer insulating layer 150 and a gate insulating layer 160 are disposed between the data lines 130 and the signal line group 120. The gate insulating layer 160 is located on the side closer to the signal line group 120, and the interlayer insulating layer 150 is located on the side closer to the data lines 130. An alignment film is disposed on the side of the driving circuit structure that is closer to the color filter substrate 200.

[0060] The color filter substrate 200 includes a second substrate 210 and a filter layer 220. The second substrate 210 can be a rigid substrate. The rigid substrate can be, for example, a glass substrate or a PMMA (Polymethyl methacrylate) substrate. The second substrate 210 can also be a flexible substrate. For example, the flexible substrate can be a PET (Polyethylene terephthalate) substrate, a PI (Polyimide) substrate, or a PEN (Polyethylene naphthalate two formic acid glycol ester) substrate. It is understood that the second substrate 210 can be of various types and can be selected and set according to actual needs, and the embodiments of the present disclosure do not limit this.

[0061] A filter layer 220 is provided on the side of the second substrate 210 near the array substrate 100. The filter layer 220 includes a black matrix 221 and a color filter layer 222. The color filter layer 222 is provided corresponding to the pixel area 400. The orthographic projection of the color filter layer 222 onto the array substrate 100 covers the pixel area 400. The color filter layer 222 includes a red color filter layer, a green color filter layer, and a blue color filter layer. Different pixel areas 400 correspond to different color filter layers 222. The orthographic projection of the black matrix 221 onto the array substrate 100 covers areas other than the pixel area 400. For example, the black matrix 221 covers structures such as the data lines 130, the signal line group 120, the transistors 170, and the spacers 320. Specifically, the orthographic projection of the black matrix 221 onto the array substrate 100 covers structures such as the data line 130, the signal line group 120, the transistor 170, and the spacer 320, and the covered structure is greater than or equal to 50 μm from the edge of the orthographic projection of the black matrix 221 onto the array substrate 100. The black matrix 221 also separates different pixel areas 400 to prevent accidents such as cross-color from occurring, which affect the final display effect. The black matrix 221 can also prevent the spacer 320 from slipping and causing abnormal display of the panel, and shielding the distance from scratches. An alignment film is provided on the side of the filter layer 220 close to the array substrate 100.

[0062] A liquid crystal layer 300 is disposed between the array substrate 100 and the color filter substrate 200. The liquid crystal layer 300 is filled with liquid crystal. Under the control of the signal line group 120, the data lines 130 charge the liquid crystal capacitor Clc and the storage capacitor Cstg in the pixel area. Under the electric field of the liquid crystal capacitor Clc, the liquid crystal molecules maintain a certain orientation, thereby controlling the intensity of light passing through the liquid crystal layer 300.

[0063] The liquid crystal layer 300 is supported between the array substrate 100 and the color filter substrate 200 by spacers 320. One end of the spacers 320 is supported by the array substrate 100, and the other end is supported by the color filter substrate 200, thereby maintaining a certain thickness of the liquid crystal layer 300. Optionally, a plurality of strip-shaped spacers 320 are provided on the side of the color filter substrate 200 close to the array substrate 100. The strip-shaped spacers 320 extend along the second direction F2, and their orthographic projection onto the array substrate 100 partially overlaps with the signal line group 120.

[0064] As shown in Figures 1 to 5, in an optional embodiment, the signal line group 120 includes a first signal line 121 and a second signal line 122. The first signal line 121 controls the connection between the data line 130 and the liquid crystal capacitor Clc and the storage capacitor Cstg through a transistor 170. That is, the first signal line 121 controls whether the data line 130 charges the liquid crystal capacitor Clc and the storage capacitor Cstg. The second signal line 122 is connected to the common electrode and provides a stable voltage to one end of the liquid crystal capacitor Clc and the storage capacitor Cstg, thereby maintaining a stable voltage difference between the liquid crystal capacitor Clc and the storage capacitor Cstg, thereby maintaining a directional deflection angle of the liquid crystal molecules. Optionally, a signal line group 120 includes one first signal line 121 and one second signal line 122. The first signal line 121 controls the on and off of the data line 130 of a row of pixel areas 400 through a plurality of transistors 170, and the second signal line 122 provides a stable voltage to one end of the liquid crystal capacitor Clc and the storage capacitor Cstg of an adjacent row of pixel areas 400.

[0065] The orthographic projection of the spacer 320 onto the array substrate 100 covers the area between the first signal line 121 and the second signal line 122 in the signal line group 120. The orthographic projection of the spacer 320 onto the array substrate 100 partially overlaps with the first signal line 121. The orthographic projection of the spacer 320 onto the array substrate 100 partially overlaps with the second signal line 122. That is, within its length, the orthographic projection of the spacer 320 onto the array substrate 100 simultaneously covers part of the first signal line 121 and part of the second signal line 122, as well as the area between the first signal line 121 and the second signal line 122. For example, the width of the spacer 320 can be a. The width of the area between the first signal line 121 and the second signal line 122 is d, that is, the distance between the first signal line 121 and the second signal line 122 in the same signal line group 120 is d. The alignment deviation between the array substrate 100 and the color filter substrate 200 is c. That is, during the alignment process, the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c. Therefore, a = d + 2c. That is, when the array substrate 100 and the color filter substrate 200 are aligned without deviation, the orthographic projection of the spacer 320 onto the array substrate 100 covers the first signal line 121 by a width of c, and the orthographic projection of the spacer 320 onto the array substrate 100 covers the second signal line 122 by a width of c. Optionally, the average width of the first signal line 121 is b, and the average width of the second signal line 122 is e. Here, b is greater than or equal to 2c, and e is greater than or equal to 2c. In this way, even if slight misalignment occurs during the alignment process between the array substrate 100 and the color filter substrate 200, the width of the overlap between the orthographic projection of the spacer 320 onto the array substrate 100 and the first signal line 121 and the second signal line 122 remains constant at 2c. This ensures that the spacer 320 provides stable support for the liquid crystal layer 300, thereby maintaining a stable thickness of the liquid crystal layer 300 and guaranteeing the display quality of the display panel. Optionally, e can be greater than b, thereby ensuring the uniformity of the voltage provided by the second signal line 122 and thus ensuring the stability of the deflection of the liquid crystal molecules.

[0066] The side of the spacer 320 facing away from the color filter substrate 200 is equidistant from the color filter substrate 200. The length of the spacer 320 is greater than the spacing between two adjacent data lines 130. The overlapping area of ​​the data lines 130 and the signal line group 120 forms a plurality of columnar structures 140 protruding toward the color filter substrate 200. The side of the spacer 320 facing away from the color filter substrate 200 abuts against some of the columnar structures 140. In this way, the spacer 320 forms distinct spacer regions within itself, cooperating with the data lines 130 and the signal line group 120. The portion of the spacer 320 facing away from the color filter substrate 200 that abuts against some of the columnar structures 140 forms a primary spacer region 321. The orthographic projection of the spacer 320 onto the array substrate 100, which overlaps with the data lines 130 or the signal line group 120 but does not overlap with the columnar structures 140, forms a first secondary spacer region 322. The portion where the orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the area between the first signal line 121 and the second signal line 122 in the signal line group 120 forms a second sub-spacer region 323. The side of the columnar structure 140 closest to the color filter substrate 200 abuts the spacer 320. The distance f between the data line 130 or the non-columnar structure 140 area on the signal line group 120 closest to the color filter substrate 200 and the spacer 320 is . The distance g between the area between the first signal line 121 and the second signal line 122 in the signal line group 120 and the spacer 320 is . g>f>0. Thus, the spacer 320, the data line 130, and the signal line group 120 cooperate to form a main spacer region 321, a first sub-spacer region 322, and a second sub-spacer region 323 with a step difference. Under normal conditions, the main spacer region 321 of the spacer 320 provides support for the liquid crystal cell thickness. When the display substrate is pressed, the color filter substrate 200 is recessed toward the array substrate 100, and the first sub-spacer region 322 contributes to supporting the thickness of the liquid crystal cell. When the display substrate is pressed more strongly, the color filter substrate 200 is further recessed toward the array substrate 100, and the second sub-spacer region 323 also begins to contribute to supporting the thickness of the liquid crystal cell.

[0067] The signal line group 120 is provided with a plurality of winding areas 123 along its length. A winding area 123 is provided at the intersection of at least one signal line group 120 and a data line 130. Specifically, a winding area 123 is provided at the intersection of at least one first signal line 121 and / or at least one second signal line 122 and a data line 130. The orthographic projection of the spacers 320 onto the array substrate 100 within the winding area 123 does not overlap with the columnar structure 140. For example, the signal line group 120 includes a first signal line 121 and a second signal line 122. The first signal line 121 and the second signal line 122 extend in the non-winding area 123 along the length direction of the signal line group 120, that is, the second direction F2. In the winding area 123, the first signal line 121 bends a distance away from the second signal line 122, and then extends along the length direction of the signal line group 120. After bypassing the columnar structure 140, it bends and extends in the direction close to the second signal line 122 to a position colinear with the first signal line 121 in the non-winding area 123, and then continues to extend along the length direction of the signal line group 120. That is, in the winding area 123, the first signal line 121 protrudes along the first direction F1 to avoid the spacer 320. Within the winding area 123, the second signal line 122 bends a distance away from the first signal line 121, then extends along the length of the signal line group 120. After bypassing the columnar structure 140, it bends and extends toward the first signal line 121 to a position collinear with the second signal line 122 in the non-winding area 123. It then continues to extend along the length of the signal line group 120. In other words, within the winding area 123, the second signal line 122 protrudes along the first direction F1 to avoid the spacer 320. In this way, the original main spacer area 321 within the winding area 123 becomes the first secondary spacer area 322. Optionally, the distance the first signal line 121 bends away from the second signal line 122 within the winding area 123 is h, and the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c, where h is greater than or equal to c. The structure in which the first signal line 121 and the second signal line 122 sandwich the spacer 320 in the winding area 123 can effectively prevent the spacer 320 from being displaced in the first direction F1 .

[0068] In some optional embodiments, a spacer 320 is provided for every twenty-four pixel areas 400 in the display substrate. For example, in twenty-four pixel areas 400 arranged in two rows and twelve columns, one spacer 320 spans at least thirteen data lines 130 along its length, meaning that the spacer 320 spans twelve pixel areas 400 along its length. The orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the thirteen data lines 130 and one signal line group 120. At least eleven of the intersections between the thirteen data lines 130 and the signal line group 120 are provided with a winding area 123. As a result, the contact density ratio between the main spacer area 321 and the first sub-spacer area 322 is close to 1:100. This ratio of the main spacer area 321 to the first sub-spacer area 322 ensures both support for the liquid crystal cell thickness and the absence of dark spots under external pressure. Of course, the arrangement of the above-mentioned spacers 320 and the arrangement of the winding area 123 can be determined according to actual needs. For example, a spacer 320 can be provided for an average of 23, 24, 25, 26 or 27 pixel areas 400. One spacer 320 spans 12, 13, 14, 15 or 16 data lines 130 in its length direction, that is, the spacer 320 spans 11, 12, 13, 14 or 15 pixel areas 400 in its length direction. The number of winding areas 123 can also be 11, 12, 13, 14 or 15. As long as the contact density of the main spacer area 321 is close to 200μm2 / mm2 and the contact density of the first sub-spacer area 322 is close to 20000μm2 / mm2, it can be sufficient. The spacer 320 spans multiple data lines 130 in its length direction. As shown in FIG3 , when the spacer 320 undergoes a significant displacement in the first direction F1, for example, when the spacer 320 displaces in the first direction F1 to the point where it no longer overlaps with the signal line group 120, the data line 130 can still provide support for the spacer 320. Specifically, when the spacer 320 undergoes a significant displacement in the first direction F1, the first sub-spacer regions 322 formed by the overlap of the main spacer region 321 with the signal line group 120 are lost, but the first sub-spacer regions 322 formed by the overlap of the data line 130 are not lost. Therefore, the significant displacement of the spacer 320 in the first direction F1 will not scratch the alignment film on the array substrate 100. Alternatively, the arrangement of the spacers 320 can be determined based on demand. For example, one main spacer region 321 and six to twelve first sub-spacer regions 322 can be provided in the twenty-four pixel regions 400 arranged in three rows and eight columns. Alternatively, in the twenty-four pixel areas 400 arranged in four rows and six columns, one main spacer area 321 and six to twelve first sub-spacer areas 322 are provided. It is sufficient that the spacers 320 are evenly distributed across the entire surface and that the contact density ratio between the main spacer areas 321 and the first sub-spacer areas 322 is close to 1:100.

[0069] Figures 6 and 7 illustrate the liquid crystal cell thickness of a display substrate with different contact densities between the main spacer region 321 and the first sub-spacer region 322, after being subjected to external force, both when the spacer 320 is not displaced and when it is displaced. The abscissa in Figures 6 and 7 represents the contact density (μm² / mm²) of the first sub-spacer region 322, and the ordinate represents the liquid crystal cell thickness (μm). The six lines from top to bottom in Figure 6 represent contact densities of 100μm² / mm², 150μm² / mm², 200μm² / mm², 250μm² / mm², 300μm² / mm², and 350μm² / mm² for the main spacer region 321, respectively. The six lines from top to bottom in Figure 7 represent contact densities of 350μm² / mm², 300μm² / mm², 250μm² / mm², 200μm² / mm², 150μm² / mm², and 100μm² / mm², respectively, for the main spacer region 321. It is clear that as the contact density of the first sub-spacer region 322 increases, the cell thickness increases after the display substrate is subjected to external forces. When the contact density of the main spacer region 321 is 200μm² / mm² and the contact density of the first sub-spacer region 322 is 20,000μm² / mm², the spacers 320 provide better support for the cell thickness.

[0070] Figure 8 shows a display substrate with different contact densities between the main spacer region 321 and the first sub-spacer region 322. The deformation of the spacer 320 after displacement and external force are applied. The horizontal axis in Figure 8 represents the contact density of the first sub-spacer region 322 (μm² / mm²), and the vertical axis represents the liquid crystal cell deformation (μm). The six lines from top to bottom in Figure 8 represent contact densities of 100μm² / mm², 150μm² / mm², 200μm² / mm², 250μm² / mm², 300μm² / mm², and 350μm² / mm² for the main spacer region 321, respectively. The thickness of the data line 130 is generally between 0.55μm and 0.65μm, and the thickness of the signal line group 120 is between 0.65μm and 0.75μm. It can be clearly seen that when the contact density of the first sub-spacer region 322 is greater than 15,000 μm2 / mm2 and the contact density of the main spacer region 321 is greater than 150 μm2 / mm2, the deformation of the spacer 320 is significantly smaller than the thickness of the data line 130. In this case, the displacement of the spacer 320 will not scratch the alignment film.

[0071] The second signal line 122 is provided with a via 124 near the intersection thereof with the data line 130. The second signal line 122 is connected to the liquid crystal capacitor Clc and the storage capacitor Cstg through the via 124. The via 124 is provided near the intersection of the second signal line 122 and the data line 130. When light leakage occurs due to the via 124, the black matrix 221 can block the light leaking from the via 124, preventing it from affecting the display effect.

[0072] As shown in Figures 9 to 11, in an optional embodiment, the signal line group 120 includes a first signal line 121. The first signal line 121 controls the connection between the data line 130 and the liquid crystal capacitor Clc and the storage capacitor Cstg, that is, the first signal line 121 controls whether the data line 130 charges the liquid crystal capacitor Clc and the storage capacitor Cstg.

[0073] Another first signal line 121 provides a stable voltage to one end of the liquid crystal capacitor Clc and the storage capacitor Cstg, thereby maintaining a stable voltage difference between the liquid crystal capacitor Clc and the storage capacitor Cstg, thereby maintaining a directional deflection angle of the liquid crystal molecules. Optionally, a signal line group 120 includes a first signal line 121. The first signal line 121 controls the on and off of the data line 130 of a row of pixel areas 400, and the first signal line 121 of an adjacent row of pixel areas 400 provides a stable voltage to one end of the liquid crystal capacitor Clc and the storage capacitor Cstg.

[0074] The orthographic projection of the spacer 320 onto the array substrate 100 covers the first signal line 121 in the signal line group 120. That is, the orthographic projection of the spacer 320 onto the array substrate 100 covers the first signal line 121 within its length.

[0075] For example, the width of the spacer 320 can be a, the width of the first signal line 121 can be b, and the alignment deviation between the array substrate 100 and the color filter substrate 200 can be c. That is, during the alignment process of the array substrate 100 and the color filter substrate 200, the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c, and a is greater than b. Alternatively, a is greater than or equal to b+2c, that is, the orthographic projection of the spacer 320 onto the array substrate 100 overlaps the first signal line 121 in the signal line group 120, and the distance between the two sides of the first signal line 121 and the two sides of the orthographic projection of the spacer 320 onto the array substrate 100 is greater than or equal to c. In this way, when a slight deviation occurs during the alignment process of the array substrate 100 and the color filter substrate 200, the width of the overlapping portion between the orthographic projection of the spacer 320 onto the array substrate 100 and the first signal line 121 is always b. In this way, it can be ensured that the spacers 320 can provide stable support for the liquid crystal layer 300, thereby ensuring that the liquid crystal layer 300 can maintain a stable thickness, thereby ensuring the display effect of the display panel.

[0076] The side of the spacer 320 facing away from the color filter substrate 200 is equidistant from the color filter substrate 200. The overlapping area of ​​the data lines 130 and the signal line group 120 forms a plurality of columnar structures 140 protruding toward the color filter substrate 200. The side of the spacer 320 facing away from the color filter substrate 200 abuts against some of the columnar structures 140. In this way, the spacer 320 forms distinct spacer regions within itself, in conjunction with the data lines 130 and the signal line group 120. The portion of the spacer 320 facing away from the color filter substrate 200 that abuts against some of the columnar structures 140 forms a primary spacer region 321. The orthographic projection of the spacer 320 onto the array substrate 100, which overlaps with the data lines 130 or the signal line group 120 but does not overlap with the columnar structures 140, forms a first secondary spacer region 322.

[0077] The orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the area of ​​the array substrate 100 not including the first signal line 121, forming a second sub-spacer region 323. The side of the columnar structure 140 near the color filter substrate 200 abuts the spacer 320. The distance f between the area of ​​the data line 130 or signal line group 120 not including the columnar structure 140 near the color filter substrate 200 and the spacer 320 is . The distance g between the area of ​​the array substrate 100 not including the first signal line 121 and the spacer 320 is . g>f>0. Thus, the spacer 320, along with the data line 130 and signal line group 120, forms a main spacer region 321, a first sub-spacer region 322, and a second sub-spacer region 323 with step differences. Under normal conditions, the main spacer region 321 of the spacer 320 provides support for the liquid crystal cell thickness. When the display substrate is pressed, the color filter substrate 200 is recessed toward the array substrate 100, and the first sub-spacer region 322 contributes to supporting the thickness of the liquid crystal cell. When the display substrate is pressed more strongly, the color filter substrate 200 is further recessed toward the array substrate 100, and the second sub-spacer region 323 also begins to contribute to supporting the thickness of the liquid crystal cell.

[0078] The signal line group 120 is provided with several winding areas 123 along its length. A winding area 123 is provided at the intersection of at least one signal line group 120 and a data line 130. The orthographic projection of the spacer 320 onto the array substrate 100 in the winding area 123 does not overlap with the columnar structure 140. For example, the signal line assembly 120 includes a first signal line 121. The first signal line 121 extends in the non-winding area 123 along the length direction of the signal line assembly 120, i.e., the second direction F2. Within the winding area 123, the first signal line 121 bends a distance perpendicular to the length direction of the signal line assembly 120. It then extends along the length direction of the signal line assembly 120, bypasses the columnar structure 140, bends back, and extends to a position colinear with the first signal line 121 in the non-winding area 123. It then continues to extend along the length direction of the signal line assembly 120. In other words, within the winding area 123, the first signal line 121 protrudes along the first direction F1 to avoid the spacer 320. In this way, the original main spacer area 321 within the winding area 123 becomes the first sub-spacer area 322. Optionally, the first signal line 121 in the winding area 123 is bent by a distance h perpendicular to the length direction of the signal line group 120 , the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c, and h is greater than or equal to c.

[0079] On average, one spacer 320 is provided for every twelve pixel areas 400 in the display substrate. For example, in twelve pixel areas 400 arranged in a row and twelve columns, one spacer 320 spans at least thirteen data lines 130 along its length, meaning that the spacer 320 spans twelve pixel areas 400 along its length. The orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the thirteen data lines 130 and one signal line group 120. At least eleven of the intersections between the thirteen data lines 130 and the signal line group 120 are provided with a winding area 123. As a result, the contact density ratio between the main spacer area 321 and the first sub-spacer area 322 is close to 1:100. This ratio of the main spacer area 321 to the first sub-spacer area 322 ensures both support for the liquid crystal cell thickness and the absence of dark spots under external pressure. Optionally, the arrangement of the spacers 320 can be determined according to needs. For example, one main spacer area 321 and six to twelve first sub-spacer areas 322 can be set in the twelve pixel areas 400 arranged in two rows and six columns. Alternatively, one main spacer area 321 and six to twelve first sub-spacer areas 322 can be set in the twenty-four pixel areas 400 arranged in three rows and four columns. It is only necessary to ensure that the spacers 320 are evenly arranged on the entire surface and that the contact density ratio between the main spacer area 321 and the first sub-spacer area 322 is close to 1:100. Of course, the arrangement of the above-mentioned spacers 320 and the arrangement of the winding area 123 can be determined according to actual needs. For example, one spacer 320 can be set for an average of 12, 13, 14, 15 or 16 pixel areas 400. One spacer 320 spans 12, 13, 14, 15, or 16 data lines 130 in its length direction, that is, the spacer 320 spans 11, 12, 13, 14, or 15 pixel areas 400 in its length direction. The number of winding areas 123 can also be 11, 12, 13, 14, or 15. As long as the contact density of the main spacer area 321 is close to 200 μm2 / mm2 and the contact density of the first sub-spacer area 322 is close to 20,000 μm2 / mm2, it can be sufficient. The spacer 320 spans multiple data lines 130 in its length direction. When the spacer 320 has a large displacement in the first direction F1, for example, when the spacer 320 is displaced in the first direction F1 to no longer overlap with the signal line group 120, the data line 130 provides support for the spacer 320. That is, when the spacer 320 undergoes a significant displacement in the first direction F1, the first sub-spacer region 322 formed by the main spacer region 321 overlapping the signal line group 120 will be lost, but the first sub-spacer region 322 formed by the data line 130 will not be lost. Therefore, the significant displacement of the spacer 320 in the first direction F1 will not scratch the alignment film on the array substrate 100.

[0080] As shown in Figures 5 and 12-13, in an alternative embodiment, the orthographic projection of the spacer 320 onto the array substrate 100 partially overlaps with the signal line group 120. The side of the spacer 320 facing away from the color filter substrate 200 is at unequal distances from the color filter substrate 200. The spacer 320 includes a main spacer region 321 having a first thickness and a first sub-spacer region 322 having a second thickness, where the first thickness is greater than the second thickness. The orthographic projection of the main spacer region 321 onto the array substrate 100 overlaps with the data lines 130, while the orthographic projection of the main spacer region 321 onto the array substrate does not overlap with the signal line group 120. The orthographic projection of the main spacer region 321 onto the array substrate 100 covers at least two data lines 130 along the length of the spacer 320. The orthographic projection of the first sub-spacer region 322 onto the array substrate 100 partially overlaps with the data lines 130 and partially overlaps with the signal line group 120.

[0081] The signal line group 120 is provided with several winding areas 123 along its length. A winding area 123 is provided at the intersection of at least one signal line group 120 and a data line 130. Within the winding area 123, the signal line group 120 avoids the area where the spacer 320 and the data line 130 overlap. That is, the spacer 320, the signal line group 120, and the data line 130 do not overlap simultaneously. Furthermore, the winding area 123 is also provided at the position of the orthographic projection of the main spacer area 321 onto the array substrate 100. Within the winding area 123, the signal line group 120 avoids the area covered by the orthographic projection of the main spacer area 321 onto the array substrate 100. The maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c. Therefore, the distance between the signal line group 120 in the winding area 123 and the area where the spacers 320 and the data lines 130 overlap is greater than c, and the distance between the signal line group 120 in the winding area 123 and the area covered by the orthographic projection of the main spacer area 321 onto the array substrate 100 is greater than c. That is, the orthographic projection of the first sub-spacer area 322 in the winding area 123 onto the array substrate 100 overlaps with the data lines 130, and the orthographic projection of the first sub-spacer area 322 in the non-winding area 123 onto the array substrate 100 overlaps with the signal line group 120.

[0082] On average, one spacer 320 is provided for every twenty-four pixel areas 400 in the display substrate. For example, in twenty-four pixel areas 400 arranged in two rows and twelve columns, one spacer 320 spans at least thirteen data lines 130 along its length, meaning that the spacer 320 spans twelve pixel areas 400 along its length. The orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the thirteen data lines 130 and with one signal line group 120. A winding area 123 is provided at each intersection of the thirteen data lines 130 and the signal line group 120. Each spacer 320 is provided with a main spacer area 321. Thus, the contact density ratio between the main spacer area 321 and the first sub-spacer area 322 is close to 1:100. The main spacer area 321 and the first sub-spacer area 322 with this proportional contact density can both meet the requirements of supporting the thickness of the liquid crystal cell and meet the requirement of no dark spots under external pressure. Optionally, the arrangement of the spacers 320 can be determined according to needs. For example, one main spacer area 321 and six to twelve first sub-spacer areas 322 can be set in the twenty-four pixel areas 400 arranged in three rows and eight columns. Alternatively, one main spacer area 321 and six to twelve first sub-spacer areas 322 can be set in the twenty-four pixel areas 400 arranged in four rows and six columns, and so on. It is only necessary to ensure that the spacers 320 are evenly arranged on the entire surface and that the contact density ratio of the main spacer area 321 to the first sub-spacer area 322 is close to 1:100. Of course, the arrangement of the above-mentioned spacers 320 and the arrangement of the winding area 123 can be determined according to actual needs. A spacer 320 may be provided for an average of 23, 24, 25, 26, or 27 pixel regions 400. One spacer 320 may span 12, 13, 14, 15, or 16 data lines 130 along its length, meaning that the spacer 320 spans 11, 12, 13, 14, or 15 pixel regions 400 along its length. The number of winding regions 123 may also be 11, 12, 13, 14, or 15. This is sufficient as long as the contact density of the main spacer region 321 is close to 200 μm² / mm² and the contact density of the first sub-spacer region 322 is close to 20,000 μm² / mm². The spacer 320 spans multiple data lines 130 along its length. When the spacer 320 undergoes a significant displacement in the first direction F1, for example, when the spacer 320 is displaced in the first direction F1 to the point where it no longer overlaps with the signal line group 120, the data line 130 can still provide support for the spacer 320. Specifically, when the spacer 320 undergoes a significant displacement in the first direction F1, the first sub-spacer region 322 formed by the overlap of the main spacer region 321 with the signal line group 120 is lost, but the first sub-spacer region 322 formed by the overlap with the data line 130 is not lost. Furthermore, since the main spacer region 321 of the spacer 320 overlaps with the data line 130, its support capacity is not lost due to the displacement of the spacer 320 in the first direction F1.Therefore, a large displacement of the spacer 320 in the first direction F1 will not scratch the alignment film on the array substrate 100 .
