Description

Technical Field

[0001] The present application belongs to the field of display, and specifically relates to a display panel and a display device. Background Art

[0002] The liquid crystal display panel is the main component of the liquid crystal display. The liquid crystal display panel includes an array substrate and an opposing substrate arranged in a box, and a liquid crystal layer filled between the array substrate and the opposing substrate. The accuracy and uniformity of the thickness of the liquid crystal layer are crucial to the display quality. In order to make the thickness of the liquid crystal layer uniform, some spacers need to be set between the array substrate and the opposing substrate.

[0003] Since the display area of ​​the liquid crystal display panel is inconsistent with the height of its peripheral area, the height of the spacers formed is also inconsistent. Usually, the height of the spacers in the peripheral area is lower than the height of the spacers in the display area. This causes the array substrate and the opposing substrate to easily bend inward when squeezed, which in turn causes uneven thickness of the liquid crystal layer. The liquid crystal display panel will display uneven images, affecting the display effect. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0048] Embodiment 1

[0049] See also Figure 1 and Figure 2 As shown, in this embodiment, the display panel includes a first substrate 100, a second substrate 200, a first magnetic structure 300 and a second magnetic structure 400. The first substrate 100 and the second substrate 200 are arranged in a box, and the first magnetic structure 300 and the second magnetic structure 400 are both arranged between the first substrate 100 and the second substrate 200. The orthographic projections of the first magnetic structure 300 and the second magnetic structure 400 on the first substrate 100 overlap, and the first magnetic structure 300 and the second magnetic structure 400 can be arranged relatively to each other.

[0050] The first magnetic structure 300 and the second magnetic structure 400 are both located between the first substrate 100 and the second substrate 200, and the polarities of the opposite sides of the first magnetic structure 300 and the second magnetic structure 400 are the same. Assuming that the first substrate 100 and the second substrate 200 are placed in the vertical direction, the first magnetic structure 300 and the second magnetic structure 400 are arranged relative to each other, that is, they are opposite to each other in the vertical direction, so that the opposite sides of the first magnetic structure 300 and the second magnetic structure 400 have the same polarities and repel each other. The first magnetic structure 300 and the second magnetic structure 400 can be aligned in the vertical direction, that is, the center line of the first magnetic structure 300 coincides with the center line of the second magnetic structure 400.

[0051] The display panel further includes a sealant 600 and a liquid crystal layer, both of which are disposed between the first substrate 100 and the second substrate 200, the liquid crystal layer is located on the inner side of the sealant 600, and the first magnetic structure 300 and the second magnetic structure 400 are located on the outer side of the sealant 600. In other words, the first magnetic structure 300 and the second magnetic structure 400 are both located in the non-display area of ​​the display panel, and the liquid crystal layer is located in the display area of ​​the display panel. There are multiple spacer columns 500, some of which are located in the display area, and some of which are located in the non-display area.

[0052] The first substrate 100 may be an array substrate including a base substrate and a thin film transistor layer 110 . The second substrate 200 may be a color filter substrate including a base substrate and a color filter layer 210 .

[0053] It should be noted that the first magnetic structure 300 and the second magnetic structure 400 can be aligned in the vertical direction, but not limited to this. The first magnetic structure 300 and the second magnetic structure 400 can also be staggered by a certain distance to the left and right, so that the first magnetic structure 300 and the second magnetic structure 400 have a certain repulsive force, which can be determined according to the specific situation. The orthographic projections of the first magnetic structure 300 and the second magnetic structure 400 on the first substrate 100 overlap, but not limited to this. The first magnetic structure 300 and the second magnetic structure 400 do not overlap but have a certain repulsive force between each other.

[0054] The first magnetic structure 300 and the second magnetic structure 400 are both located in the non-display area of ​​the display panel, but not limited thereto. The first magnetic structure 300 and the second magnetic structure 400 may also be arranged in the non-light-transmitting area of ​​the display area, depending on the specific situation. The second substrate 200 may be a color filter substrate, and the color filter substrate includes a color filter layer 210, but not limited thereto. The color filter layer 210 may also be arranged on the thin film transistor layer 110, that is, the COA (Color Filter on Array) technology is used to reduce the difficulty of the cell process in the display panel preparation process, depending on the specific situation.

[0055] The display area and non-display area of ​​the liquid crystal display panel have inconsistent heights, and the heights of the spacer columns 500 formed are also inconsistent. Usually, the height of the spacer columns 500 in the non-display area is lower than the height of the spacer columns 500 in the display area. When the motherboard of the display panel is divided from between the two frame glues 500, a seesaw effect is easily formed, that is, the first substrate 100 and the second substrate 200 in the non-display area are squeezed and bent inwardly, and the first substrate 100 and the second substrate 200 in the display area bulge outward, which leads to uneven thickness of the liquid crystal layer.

[0056] In this embodiment, the first magnetic structure 300 and the second magnetic structure 400 are both located between the first substrate 100 and the second substrate 200, the orthographic projections of the first magnetic structure 300 and the second magnetic structure 400 on the first substrate 100 overlap, the polarities of the opposite sides of the first magnetic structure 300 and the second magnetic structure 400 are the same, the display panel further includes a sealant 600 and a liquid crystal layer, the sealant 600 and the liquid crystal layer are both arranged between the first substrate 100 and the second substrate 200, the liquid crystal layer is located on the inner side of the sealant 600, and the first magnetic structure 300 and the second magnetic structure 400 are located on the outer side of the sealant 600. When the motherboard of the display panel is divided from between the two sealants 500, the first substrate 100 and the second substrate 200 on the outer side of the sealant 500 need to overcome the repulsive force between the first magnetic structure 300 and the second magnetic structure 400, the first substrate 100 and the second substrate 200 on the outer side of the sealant 500 are not easy to bend and deform inward, and the first substrate 100 and the second substrate 200 on the inner side of the sealant 500 will not bulge outward, that is, no seesaw effect will be formed.

[0057] The first substrate 100 and the second substrate 200 are not easily deformed, which can improve the problem of uneven thickness of the liquid crystal layer and further reduce the problem of uneven display.

[0058] See also Figure 1 and Figure 2 As shown, the display panel further includes a spacer column 500, the spacer column 500 and the second magnetic structure 400 are both disposed on the second substrate 200, the first magnetic structure 300 is disposed on the first substrate 100, and there is a gap between the first magnetic structure 300 and the second magnetic structure 400. When the second substrate 200 is a color filter substrate, the color filter layer 210 is disposed on the base substrate, and the spacer column 500 and the second magnetic structure 400 are both disposed on the color filter layer 210; when the first substrate 100 is an array substrate, the thin film transistor layer 110 is disposed on the base substrate, and the first magnetic structure 300 is disposed on the thin film transistor layer 110.

[0059] It should be noted that the spacer column 500 can be arranged on the first substrate 100, but it is not limited to this. The spacer column 500 can also be arranged on the second substrate 200, which can be determined according to the specific situation. The first magnetic structure 300 can be arranged on the first substrate 100, and the second magnetic structure 400 can be arranged on the second substrate 200, but it is not limited to this. The first magnetic structure 300 and the second magnetic structure 400 can also be arranged at both ends of the spacer column 500, which can be determined according to the specific situation. The first magnetic structure 300 and the second magnetic structure 400 are arranged at both ends of the spacer column 500, and the spacer column 500 is not easily deformed by compression, and can also reduce the inward bending deformation of the first substrate 100 and the second substrate 200 when being squeezed to a certain extent. There is a gap between the first magnetic structure 300 and the second magnetic structure 400, but it is not limited to this. The first magnetic structure 300 and the second magnetic structure 400 can also be in contact with each other, which can be determined according to the specific situation.

[0060] The first magnetic structure 300 is arranged on the first substrate 100, and the second magnetic structure 400 is arranged on the second substrate 200. The polarities of the opposite sides of the first magnetic structure 300 and the second magnetic structure 400 are the same. There is a mutual repulsive force between the first magnetic structure 300 and the second magnetic structure 400, and the repulsive force directly acts on the first substrate 100 and the second substrate 200. The first substrate 100 and the second substrate 200 are not easy to bend inward when squeezed.

[0061] See also Figure 1 and Figure 2As shown, the spacer column 500 is disposed on the bottom surface of the second substrate 200 close to the first substrate 100, and there is a gap between the spacer column 500 and the first substrate 100. The first magnetic structure 300 includes a first magnet 310, and the first magnet 310 is disposed on the first substrate 100. The second magnetic structure 400 includes a second magnet 410, and the second magnet 410 can be disposed on the spacer column 500, that is, the second magnet 410 is indirectly disposed on the second substrate 200 through the spacer column 500. The orthographic projection of the first magnet 310 on the first substrate 100 overlaps, and the second magnet 410 has the same polarity as the first magnet 310 on the opposite side.

[0062] It should be noted that the second magnet 410 may be disposed on the spacer column 500 , but is not limited thereto. The second magnet 410 may also be disposed on the second substrate 200 , depending on the specific circumstances.

[0063] The first magnet 310 is arranged on the first substrate 100, and the second magnet 410 is arranged on the bottom surface of the spacer column 500. Compared with the case where the second magnet 410 is arranged on the second substrate 200, when the second magnet 410 is arranged on the bottom surface of the spacer column 500, the distance between the second magnet 410 and the first magnet 310 is closer, and the repulsive force between the second magnet 410 and the first magnet 310 is greater. While ensuring that the first substrate 100 and the second substrate 200 are not deformed, the first substrate 100 and the second substrate 200 can withstand greater pressure.

[0064] See also Figure 1 and Figure 2 As shown, the first magnet 310 is disposed on the first substrate 100 , and the second magnet 410 is disposed at an end of the spacer column 500 away from the second substrate 200 , that is, the second magnet 410 is disposed on the bottom surface of the spacer column 500 .

[0065] It should be noted that the second magnet 410 can be disposed at one end of the spacer column 500 away from the second substrate 200, but is not limited thereto. The second magnet 410 can also be disposed on the side of the spacer column 500 or buried in the spacer column 500, depending on the specific situation.

[0066] The second magnet 410 is disposed at the end of the spacer column 500 away from the second substrate 200. The second magnet 410 is closer to the first magnet 310, and the repulsive force between the second magnet 410 and the first magnet 310 is greater. While ensuring that the first substrate 100 and the second substrate 200 are not deformed, the first substrate 100 and the second substrate 200 can withstand greater pressure.

[0067] See also Figures 1 to 3As shown, the first magnet 310 is a flat plate structure, a rectangular structure or a trapezoidal structure, and is arranged opposite to the bottom surface of the spacer column 500 close to the first substrate 100. The second magnet 410 is completely arranged on the bottom surface side of the spacer column 500 close to the first substrate 100; wherein, the longitudinal section of the second magnet 410 is a trapezoid, and the width of the longitudinal section gradually decreases in the direction from the first substrate 100 to the second substrate 200. That is, the second magnet 410 has an upper end face and a lower end face opposite to each other, and a first side face 411 connecting the upper end face and the lower end face, and the angle between the first side face 411 and the first magnet 310 is less than 90 degrees, that is, the second magnet 410 can be a truncated cone structure. The diameter of the upper end face of the second magnet 410 is greater than the diameter of the lower end face, and the upper end face of the second magnet 410 contacts the spacer column 500. The first magnet 310 can be arranged as a circular flat plate, and the radius of the first magnet 310 is greater than the diameter of the lower end face of the second magnet 410. There may be a certain gap between the first magnet 310 and the second magnet 410 .

[0068] It should be noted that the first magnet 310 can be set as a circular flat plate, but is not limited to this. The shape of the first magnet 310 can also be set to a square or other arbitrary shape. The size of the first magnet 310 can also be smaller than the first magnet 310, which can be determined according to the specific situation. There can be a certain gap between the first magnet 310 and the second magnet 410, but is not limited to this. The first magnet 310 and the second magnet 410 can also be in contact, which can be determined according to the specific situation.

[0069] The second magnet 410 has a first side surface 411, and the angle between the first side surface 411 and the first magnet 310 is less than 90 degrees. Such a configuration can increase the size of the second magnet 410 to a certain extent, and the repulsive force between the second magnet 410 and the first magnet 310 is greater. The first magnet 310 is configured as a flat plate structure, and the second magnet 410 is configured as a truncated cone structure. The first magnet 310 and the second magnet 410 have a simple structure, which can reduce the manufacturing cost. There is a certain gap between the first magnet 310 and the second magnet 410, which can prevent the repulsive force between the first magnet 310 and the second magnet 410 from being greater, and also prevent the overall height of the first magnet 310, the second magnet 410 and the spacer column 500 from being too large.

[0070] Embodiment 2

[0071] The main difference between the second embodiment and the first embodiment is that the first magnetic structure 300 further includes a third magnet 320 , and the second magnetic structure 400 includes a fourth magnet 420 .

[0072] See also Figure 4As shown, the first magnetic structure 300 also includes a third magnet 320, which is disposed on the first substrate 100. The second magnetic structure 400 includes a fourth magnet 420, which is disposed on the second substrate 200, and the fourth magnet 420 and the third magnet 320 have the same polarity on opposite sides. The third magnet 320 and the first magnet 310 can be integrally connected, and the fourth magnet 420 can be disposed adjacent to the spacer column 500. For example, the fourth magnet 420 can be arranged in an annular structure and disposed around the spacer column 500. The first magnet 310, the second magnet 410, the third magnet 320 and the fourth magnet 420 can all be made of rare earth permanent magnet material, ferrite permanent magnet material, aluminum nickel cobalt permanent magnet material or iron chromium cobalt permanent magnet material.

[0073] It should be noted that the third magnet 320 can be integrally connected with the first magnet 310, but is not limited thereto. The third magnet 320 can also be independently arranged from the first magnet 310, depending on the specific situation. The fourth magnet 420 can be arranged adjacent to the spacer column 500, but is not limited thereto. The fourth magnet 420 can also be arranged spaced apart from the spacer column 500, depending on the specific situation. The fourth magnet 420 is also not limited to being arranged in an annular structure, and can actually be arranged in any shape.

[0074] The first magnetic structure 300 also includes a third magnet 320, and the second magnetic structure 400 includes a fourth magnet 420. The fourth magnet 420 and the third magnet 320 have the same polarity on opposite sides, and there is a mutual repulsive force between the fourth magnet 420 and the third magnet 320. The repulsive force between the first substrate 100 and the second substrate 200 is further increased by the fourth magnet 420 and the third magnet 320, so that the first substrate 100 and the second substrate 200 can withstand greater pressure while ensuring that the first substrate 100 and the second substrate 200 are not deformed.

[0075] Embodiment 3

[0076] The main difference between the third embodiment and the first embodiment is that the shapes of the first magnet 310 and the second magnet 410 are different.

[0077] See also Figure 5As shown, in this embodiment, the first magnet 310 includes a first magnetic bottom plate 311, which is arranged on the first substrate 100, and the second magnet 410 includes a second magnetic bottom plate 412, which is arranged on the bottom surface of the spacer column 500 away from the second substrate 200, and the second magnetic bottom plate 412 has the same polarity as the first magnetic bottom plate 311. The second magnet 410 also includes a second magnetic side plate 413, which is connected to the second magnetic bottom plate 412 and covers the side of the spacer column 500. The spacer column 500 can be a truncated cone structure, and the angle between the side of the spacer column 500 and the first magnetic bottom plate 311 is less than 90 degrees, and the second magnetic side plate 413 has the same polarity as the first magnetic bottom plate 311. The first magnetic bottom plate 311 can be set as a circular flat plate, and the downward orthographic projection of the second magnet 410 is located in the first magnetic bottom plate 311.

[0078] It should be noted that the first magnetic bottom plate 311 can be set as a circular flat plate, but is not limited thereto, and the specific shape of the first magnetic bottom plate 311 can also be set arbitrarily, depending on the specific situation. The downward orthographic projection of the second magnet 410 can be located inside the first magnetic bottom plate 311, but is not limited thereto, and the downward orthographic projection of the second magnet 410 can also be partially located outside the first magnetic bottom plate 311, depending on the specific situation.

[0079] The second magnet 410 includes a second magnetic bottom plate 412 and a second magnetic side plate 413. The second magnetic side plate 413 is arranged on the side of the spacer column 500. The second magnetic side plate 413 has the same polarity as the opposite side of the first magnetic bottom plate 311. Adding the second magnetic side plate 413 can increase the repulsive force between the first substrate 100 and the second substrate 200, ensuring that the first substrate 100 and the second substrate 200 are not deformed, and the first substrate 100 and the second substrate 200 can withstand greater pressure.

[0080] See also Figure 5 As shown, the first magnet 310 further includes a first magnetic side plate 312 , which is disposed on a side of the first magnetic bottom plate 311 close to the spacer column 500 , and the second magnetic side plate 413 has the same polarity as the side opposite to the first magnetic side plate 312 .

[0081] The first magnet 310 also includes a first magnetic side plate 312, which is arranged on the side of the first magnetic bottom plate 311 close to the spacer column 500. The distance from the first magnetic side plate 312 to the second magnetic side plate 413 is smaller than the distance from the first magnetic bottom plate 311 to the second magnetic side plate 413. Therefore, adding the first magnetic side plate 312 can increase the repulsive force between the first substrate 100 and the second substrate 200, ensuring that the first substrate 100 and the second substrate 200 are not deformed, and the first substrate 100 and the second substrate 200 can withstand greater pressure.

[0082] See also Figure 5 As shown, when the first magnet 310 includes the first magnetic side plate 312, the second magnetic side plate 413 is disposed around the spacer column 500, and the first magnetic side plate 312 is disposed around the second magnetic side plate 413. The first magnetic bottom plate 311 and the second magnetic bottom plate 412 can be spaced apart, and the first magnetic side plate 312 and the second magnetic side plate 413 can also be spaced apart.

[0083] It should be noted that the first magnetic side plate 312 can be arranged around the second magnetic side plate 413, but is not limited to this. The first magnetic side plate 312 can also be arranged only on one side of the second magnetic side plate 413, depending on the specific situation. The first magnetic side plate 312 and the second magnetic side plate 413 can be arranged at intervals, but is not limited to this. The first magnetic side plate 312 and the second magnetic side plate 413 can also be in contact, depending on the specific situation.

[0084] The second magnetic side plate 413 is disposed around the spacer column 500 , and the first magnetic side plate 312 is disposed around the second magnetic side plate 413 . The first magnetic side plate 312 can limit the lateral sliding of the spacer column 500 , thereby reducing the difficulty of aligning the first substrate 100 and the second substrate 200 .

[0085] Embodiment 4

[0086] The main difference between the fourth embodiment and the first embodiment is that the spacer column 500 is different.

[0087] See also Figure 6 As shown, in this embodiment, the spacer column 500 is a magnetic material structural member, and the second magnetic structure 400 includes the spacer column 500, that is, the spacer column 500 serves as the second magnet 410. The spacer column 500 can be made of a magnetic material as a whole, and the magnetic material includes a rare earth permanent magnet material, a ferrite permanent magnet material, an aluminum nickel cobalt permanent magnet material, or an iron chromium cobalt permanent magnet material. The first magnetic structure 300 includes a first magnet 310, and the first magnet 310 has the same polarity as the spacer column 500 on the opposite side.

[0088] The spacer column 500 can be made of magnetic material as a whole, but is not limited to this. Magnetic material particles can also be filled in the spacer column 500 to make the spacer column 500 a magnetic material structural member. The spacer column 500 has the same polarity as the opposite side of the first magnet 310, which can be determined according to the specific situation.

[0089] The spacer column 500 is a magnetic material structural part. The spacer column 500 serves as the second magnet 410. The spacer column 500 and the first magnet 310 have the same polarity on the opposite side. With this design, the spacer column 500 and the second magnet 410 do not need to be formed separately using two processes, which can reduce the complexity of the display panel process and reduce the production cost of the display panel.

[0090] Embodiment 5

[0091] The main difference between the fifth embodiment and the first embodiment is that the structure of the first substrate 100 in the fifth embodiment is different from that of the first substrate 100 in the first embodiment.

[0092] See also Figure 7 As shown, a groove 121 is provided on the first substrate 100, and the first magnet 310 is provided in the groove 121. In addition to the thin film transistor layer 110, the first substrate 100 may also include other film layers such as a planar layer 120 and a passivation layer, and the groove 121 may be located in the planar layer 120. The first magnet 310 is provided in the groove 121, and may be partially located in the groove 121 and partially located outside the groove 121.

[0093] It should be noted that the groove 121 may be located in the flat layer 120, but is not limited thereto. The groove 121 may also be located in other film layers, depending on the specific situation. The first magnet 310 may be partially located in the groove 121, but is not limited thereto. The first magnet 310 may also be completely located in the groove 121, depending on the specific situation.

[0094] The first substrate 100 is provided with a groove 121, and the first magnet 310 is disposed in the groove 121. This design can prevent the first magnet 310 from sliding on the first substrate 100. In addition, the first substrate 100 is provided with a groove 121, and the spacer column 500 can be made longer so that the second magnet 410 can extend to the groove 121. This design can prevent the first substrate 100 and the second substrate 200 from sliding relative to each other.

[0095] Embodiment 6

[0096] See also Figure 8 As shown, the display device in this embodiment includes a display panel 10 and a backlight module 20 , and the display panel 10 includes the display panel 10 disclosed in the first embodiment, the second embodiment, the third embodiment and the fourth embodiment.

[0097] It should be noted that, in addition to the display panel 10 and the backlight module 20, the display device also includes other necessary components and components. Taking the display as an example, it may also include a casing, a main circuit board, a power cord, etc. Those skilled in the art may make corresponding supplements based on the specific use requirements of the display device, which will not be repeated here.

[0098] The display device includes a display panel 10, in which a first magnetic structure 300 and a second magnetic structure 400 are both located between a first substrate 100 and a second substrate 200, and opposite sides of the first magnetic structure 300 and the second magnetic structure 400 have the same polarity. There is a mutual repulsive force between the first magnetic structure 300 and the second magnetic structure 400, and the repulsive force needs to be overcome in order to squeeze the liquid crystal layer between the first substrate 100 and the second substrate 200. The first substrate 100 and the second substrate 200 are not easy to bend and deform inward when squeezed, which can improve the problem of uneven thickness of the liquid crystal layer, and further reduce the problem of uneven display.
