[0038] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0039] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only some but not all of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present disclosure.

[0040] Unless otherwise defined, technical terms or scientific terms used in the embodiments of the present disclosure shall have the ordinary meanings understood by one of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second", and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are used to distinguish different components. Similarly, the terms "include", "comprise", and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects.

The terms "upper", "lower", "left", "right", and the like are used only to indicate relative positions, and when the absolute positions of the described objects are changed, the relative positions can also be changed accordingly.

[0041] As used herein, "parallel", "perpendicular" include the stated case and a case similar to the stated case within an acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art considering the measurement being discussed and the error related to the measurement of a specific quantity (i.e., the limitation of the measurement system). For example, "parallel" includes absolute parallel and approximate parallel, wherein the acceptable deviation range of approximate parallel may, for example, be within 5°; "perpendicular" includes absolute perpendicular and approximate perpendicular, wherein the acceptable deviation range of approximate perpendicular may, for example, also be within 5°.

[0042] It should be understood that when a layer or element is referred to as being "on" another layer or substrate, it can be directly on the other layer or substrate, or an intervening layer can also be present between the layer or element and the other layer or substrate.

[0043] Exemplary embodiments are described herein with reference to cross-sectional and / or plan view illustrations that are schematic illustrations of idealized embodiments. Variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and / or tolerances, are to be expected. Thus, embodiments should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. The regions illustrated in the figures are schematic and many of the regions are not drawn to scale. The same reference numerals in different figures are intended to represent the same, similar, or equivalent structures.

[0044] In the related art, a privacy display product includes a first display panel and a second display panel stacked together, wherein the second display panel is located on the outgoing side of the first display panel. The first display panel is used to display a picture, and the second display panel is used to adjust the angle of the light rays emitted by the first display panel to achieve a privacy effect. The second display panel includes a display substrate and a counter substrate, and a plurality of support columns are arranged on the side of the display substrate close to the counter substrate. In some embodiments, the plurality of support columns are periodically arranged according to a certain rule. In this case, the periodically arranged support columns will cause the display panel to have uneven brightness after being stacked with the display substrate and the counter substrate, resulting in various traces such as visibility mura and the like.

[0045] Therefore, in order to at least alleviate or solve one of the above-mentioned technical problems, the present disclosure provides a display panel and a manufacturing method thereof, and a display device.

[0046] In some embodiments, the present disclosure provides a display panel. Figure 1 is a plan view of a display panel in some embodiments of the present disclosure, Figure 2 is a plan view of a display panel in some embodiments of the present disclosure. In some embodiments, as Figure 1 and Figure 2 shown in FIG. 1, the display panel of the present disclosure includes a display substrate and a plurality of support columns 1 located on one side of the display substrate. Each support column 1 corresponds to a preset position 1’. The plurality of support columns 1 includes a plurality of support column groups 10, and each support column group 10 includes a plurality of first support columns 11. The connecting lines of the preset positions 1’ of the plurality of first support columns 11 in each support column group 10 form a virtual polygon. For example, in the embodiment shown in FIG. 1, each support column group 10 includes six first support columns 11, and the connecting lines of the preset positions 1’ of the six first support columns 11 in the same support column group 10 form a virtual hexagon. Figure 1 For example, in the embodiment shown in FIG. 1, each support column group 10 includes six first support columns 11, and the connecting lines of the preset positions 1’ of the six first support columns 11 in the same support column group 10 form a virtual hexagon. Figure 2In the embodiment shown, each isolation column group 10 includes four first isolation columns 11, and the connecting lines of the preset positions 1' of the four first isolation columns 11 in the same isolation column group 10 form a virtual quadrilateral.

[0047] The display substrate includes a plurality of pixel units 20 and the plurality of pixel units 20 are arranged in multiple rows.

[0048] The actual position of the isolation column 1 in the coordinate system has coordinates (x, y) = (x' + δx, y' + δy), where (x', y') are the coordinates of the preset position 1' of the isolation column 1. δx = ±0.5 × xo × Q, δy = ±0.5 × yo × P, where Q and P are random values in the range of 0-1; xo and yo are two non-zero preset values.

[0049] Optionally, the values of xo and yo can be different. In this case, the actual position of the isolation column 1 falls within a quadrilateral range centered at (x', y') and having side lengths of xo and yo, respectively. For example, the actual position of the isolation column 1 falls within a rectangular range centered at (x', y') and having side lengths of xo and yo, respectively.

[0050] Optionally, the values of xo and yo can be the same. In this case, the actual position of the isolation column 1 falls within a quadrilateral range centered at (x', y') and having a side length of xo or yo, respectively. For example, the actual position of the isolation column 1 falls within a square range centered at (x', y') and having a side length of xo.

[0051] Specifically, for example, in the embodiment shown in Figure 1 and Figure 2 xo and yo are equal and equal to the side length of a square centered at the coordinates (x', y') of the preset position 1' and having a side length of xo.

[0052] One of the horizontal axis x and the vertical axis y of the coordinate system is parallel to the row direction of the pixel unit arrangement, and the other of the horizontal axis x and the vertical axis y is perpendicular to the row direction of the pixel unit 20 arrangement. For example, in the embodiment shown in Figure 1 and Figure 2 the horizontal axis x of the coordinate system is parallel to the row direction of the pixel unit 20 arrangement, and the vertical axis y is perpendicular to the row direction of the pixel unit 20 arrangement.

[0053] In the embodiments of the present disclosure, the coordinates (x, y) of the actual positions of the isolation columns 1 are generated based on the coordinates (x', y') of the preset positions of the isolation columns 1, so that the actual positions of the isolation columns 1 are generated without a fixed period and in a random manner, thereby avoiding the problem of visual Mura caused by the stacking of the isolation columns 1 and the display substrate. Further, the relationship between the coordinates (x, y) of the actual positions and the coordinates (x', y') of the preset positions 1' is set as (x, y) = (x' + δx, y' + δy), where δx = ±0.5 × xo × Q, δy = ±0.5 × yo × P, Q and P are random values in the range of 0-1, xo and yo are two non-zero preset values, and the positive and negative signs on the right side of the equation are also randomly selected. In this case, since Q and P are random values and the positive and negative signs are randomly selected, it can be ensured that the actual positions of the isolation columns 1 all fall within the quadrilateral range with the coordinates (x', y') of the preset positions as the center and the side lengths of xo and yo, thereby ensuring the distribution density of the isolation columns 1 and further ensuring the support stability of the isolation columns.

[0054] It should be noted that the distribution density of the isolation columns 1 refers to the number of the isolation columns 1 per unit area.

[0055] In some embodiments, the ratio of the side length of the virtual polygon to the side length of the pixel unit is in the range of 0.5-0.8. For example, the ratio of the side length of the virtual polygon to the side length of the pixel unit can be 0.50, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0.58, 0.59, 0.60, 0.61, 0.62, 0.63, 0.64, 0.65, 0.66, 0.67, 0.68, 0.69, 0.70, 0.71, 0.72, 0.73, 0.74, 0.75, 0.76, 0.77, 0.78, 0.79, or 0.80.

[0056] In the embodiments of the present disclosure, by setting the ratio of the side length of the virtual polygon to the side length of the pixel unit in the range of 0.5-0.8, the distribution density of the isolation columns 1 can be ensured, thereby ensuring the support stability of the isolation columns.

[0057] Figure 3 is a schematic plan view of the isolation columns in some embodiments of the present disclosure. In some embodiments, as shown in Figure 3 each isolation column group 10 further includes a second isolation column 12. The preset position 1' of the second isolation column 12 is located at the center of a virtual polygon formed by the connecting lines of the preset positions 1' of the plurality of first isolation columns 11 in the corresponding isolation column group 10.

[0058] In the embodiments of the present disclosure, the second isolation column 12 is arranged at the center of the polygon formed by the connecting lines of the preset positions 1' of the plurality of first isolation columns 11 in the isolation column group 10, so as to further ensure the aperiodicity of the plurality of isolation columns 1, thereby avoiding the problem of visual Mura caused by the stacking of the isolation column 1 and the display substrate, and further ensuring the support stability of the isolation column.

[0059] In some embodiments, the sides of the virtual polygon are equal in length. For example, in the embodiments shown in Figure 1 In the embodiments shown, the sides of the virtual hexagon are equal in length. Further, the polygon is a regular hexagon. For another example, in the embodiments shown in Figure 2 In the embodiments shown, the sides of the virtual quadrilateral are equal in length. Further, the polygon is a square.

[0060] In the embodiments of the present disclosure, the sides of the virtual polygon are equal in length, so as to further ensure the aperiodicity of the plurality of isolation columns 1, thereby avoiding the problem of visual Mura caused by the stacking of the isolation column 1 and the display substrate.

[0061] In some embodiments, as shown in Figure 1 and Figure 2 The virtual polygon has a first side L1, and the first side L1 is perpendicular or parallel to the row direction of the arrangement of the pixel units.

[0062] For example, as shown in Figure 1 and Figure 2 The virtual polygon has a first side L1, and the first side L1 is parallel to the row direction of the arrangement of the pixel units 20.

[0063] In some embodiments, the virtual polygon has a first side L1, and the included angle between the first side L1 and the row direction of the arrangement of the pixel units ranges from 15° to 30°. For example, the included angle between the first side L1 and the row direction of the arrangement of the pixel units ranges from 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29° or 30°.

[0064] In other embodiments, the virtual polygon has a first side L1, and the included angle between the first side L1 and the row direction of the arrangement of the pixel units 20 ranges from 60° to 75°. For example, the included angle between the first side L1 and the row direction of the arrangement of the pixel units 20 ranges from 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, 70°, 71°, 72°, 73°, 74° or 75°. It can also be understood that the included angle between the first side L1 and the first direction ranges from 15° to 30°, wherein the first direction is perpendicular to the row direction of the arrangement of the pixel units 20.

[0065] The polygon in the embodiments of the present disclosure can be understood as rotating a polygon with the first side L1 perpendicular or parallel to the row direction of the pixel unit arrangement clockwise or counterclockwise by a certain angle.

[0066] In the embodiments of the present disclosure, the angle between one side of the virtual polygon and the row direction of the pixel unit arrangement is set in the range of 15°-30°, or the angle between one side of the polygon and the first direction is set in the range of 15°-30°, which can further ensure the aperiodicity of the plurality of isolation columns 1, thereby avoiding the problem of visibility Mura caused by the display substrate stack after the isolation column 1.

[0067] Figure 4 is a plan view of another isolation column of the present disclosure. Figure 5 is a plan view of still another isolation column of the present disclosure. In some embodiments, as shown in Figure 4 and Figure 5 The plurality of isolation column groups 10 are arranged in multiple rows and multiple columns. In the same row, adjacent two isolation column groups 10 share at least one isolation column 1, for example, the virtual polygons corresponding to the adjacent two isolation column groups 10 in the same row share at least one side; and / or, in the same column, adjacent two isolation column groups 10 share at least one isolation column 1, for example, the virtual polygons corresponding to the adjacent two isolation column groups 10 in the same column share at least one side.

[0068] For example, in one example, adjacent two isolation column groups 10 in the same row share at least one isolation column 1. In another example, adjacent two isolation column groups 10 in the same column share at least one isolation column 1. In another example, adjacent two isolation column groups 10 in the same row share at least one isolation column 1, and adjacent two isolation column groups 10 in the same column share at least one isolation column 1.

[0069] Specifically, in the embodiment shown in Figure 4 , adjacent two isolation column groups 10 in the same row share at least one isolation column 1, and adjacent two isolation column groups 10 in the same column share at least one isolation column 1. In the embodiment shown in Figure 5 , the last adjacent isolation column group 10 in the same row shares at least one isolation column 1.

[0070] It should be noted that in the embodiments of the present disclosure, adjacent two isolation column groups 10 share at least one isolation column 1, which can be adaptively set according to the size of the display panel.

[0071] In the embodiments of the present disclosure, by sharing at least one isolation column 1 between two adjacent isolation column groups 10 in the same column and / or sharing at least one isolation column 1 between two adjacent isolation column groups 10 in the same row, it can be ensured that there is an isolation column 1 in the square range with a preset position of the isolation column as the center and a side length as the setting value on one side of the entire display panel, thereby ensuring the supporting effect of the edge isolation column.

[0072] In some embodiments, the ratio of the distribution density of the isolation columns 1 to the distribution density of the pixel units 20 is in the range of 1-5. For example, the ratio of the distribution density of the isolation columns 1 to the distribution density of the pixel units can be 1, 2, 3, 4, or 5.

[0073] It should be noted that the distribution density of the pixel units 20 in the embodiments of the present disclosure refers to the number of pixel units per unit area.

[0074] In the embodiments of the present disclosure, by ensuring that the ratio of the distribution density of the isolation columns 1 to the distribution density of the pixel units is in the range of 1-5, the distribution density of the isolation columns 1 can be ensured, thereby ensuring the supporting stability of the isolation columns.

[0075] In some embodiments, δx and / or δy in the relationship between the coordinates (x, y) of the actual position of the at least two isolation columns 1 and the coordinates (xo, yo) of the preset position are different.

[0076] For example, in one example, δx in the relationship between the coordinates (x, y) of the actual position of the at least two isolation columns 1 and the coordinates (xo, yo) of the preset position is different. For another example, in one example, δy in the relationship between the coordinates (x, y) of the actual position of the at least two isolation columns 1 and the coordinates (xo, yo) of the preset position is different. For yet another example, in one example, δx and δy in the relationship between the coordinates (x, y) of the actual position of the at least two isolation columns 1 and the coordinates (xo, yo) of the preset position are different.

[0077] Further, when δx is different, since δx = ±0.5×xo×Q, the sign in the calculation process can be different, or the value of Q can be different. Similarly, when δy is different, since δy = ±0.5×yo×P, the sign in the calculation process can be different, or the value of P can be different.

[0078] Specifically, in some embodiments, in each isolation column group 10, δx and / or δy in the relationship between the coordinates (x, y) of the actual position of the at least two isolation columns 1 and the coordinates (x’, y’) of the preset position are different.

[0079] In the embodiments of the present disclosure, by setting the δx and / or δy in the relationship between the coordinates (x, y) of the actual position of the at least two isolation columns 1 and the coordinates (x', y') of the preset position to be different in each isolation column group 10, it can be ensured that the isolation columns 1 in each isolation column group 10 are irregularly arranged. Further, the plurality of isolation column groups 10 are also irregularly arranged as a whole, thereby avoiding the problem of visual Mura caused by the stacking of the isolation columns 1 and the display substrate.

[0080] In other embodiments, the δx and / or δy in the relationship between the coordinates (x, y) of the actual position of the isolation columns 1 located at the same position in different isolation column groups 10 and the coordinates (x', y') of the preset position are different in different isolation column groups 10. It should be noted that the isolation columns 1 located at the same position in different isolation column groups 10 can be understood as: the plurality of isolation columns 1 are respectively located in different isolation column groups 10, but the position of each isolation column 1 in the isolation column group 10 is the same.

[0081] In the embodiments of the present disclosure, by setting the δx and / or δy in the relationship between the coordinates (x, y) of the actual position of the isolation columns 1 located at the same position in different isolation column groups 10 and the coordinates (x', y') of the preset position to be different in different isolation column groups 10, it can be ensured that the plurality of isolation column groups 10 are arranged non-periodically as a whole, thereby avoiding the problem of visual Mura caused by the stacking of the isolation columns 1 and the display substrate.

[0082] That is, in the embodiments of the present disclosure, as long as the δx and / or δy in the relationship between the coordinates (x, y) of the actual position of the at least two isolation columns 1 and the coordinates (x', y') of the preset position are different, the two isolation columns 1 can be two isolation columns 1 in the same isolation column group 10, can be isolation columns 1 located at the same position in different isolation column groups 10, or both of the above. The embodiments of the present disclosure can ensure that the plurality of isolation column groups 10 are arranged non-periodically as a whole, thereby avoiding the problem of visual Mura caused by the stacking of the isolation columns 1 and the display substrate.

[0083] The present disclosure provides a display device, which includes the display panel of any of the embodiments of the present disclosure. Optionally, the display device of the embodiments of the present disclosure includes a peep-proof module, and the peep-proof module includes the display panel of any of the embodiments of the present disclosure.

[0084] In some embodiments, the display device further includes a display module arranged opposite to the display panel. The display module includes a display substrate. The display substrate includes a plurality of pixel structures. And the pixel structures 30 are arranged one-to-one corresponding to the pixel units 20.

[0085] Figure 6is a plan view of a pixel structure in some embodiments of the present disclosure. In some embodiments, as shown in Figure 6 The pixel structure 30 includes a plurality of sub-pixels arranged side by side, and the light-emitting colors of the sub-pixels include at least two colors.

[0086] For example, in the embodiment shown in Figure 6 The pixel structure 30 includes a first sub-pixel 31, a second sub-pixel 32, and a third sub-pixel 33 arranged side by side, and the light-emitting colors of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 are all different. Further, the light-emitting colors of the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 include blue, red, and yellow, respectively.

[0087] The display module in the embodiments of the present disclosure can include, but is not limited to, an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Display), an LED (Light Emitting Display), and the like.

[0096] S5: forming the corresponding isolation column 1 on the side of the display substrate according to the coordinates (x, y).

[0097] In some embodiments, in step S4, when calculating δx and δy by δx = ±0.5 x xo x Q and δy = ±0.5 x yo x P, the values of the positive and negative signs, Q and P are random.

[0098] Optionally, AI method can be used to calculate δx and δy by δx = ±0.5 x xo x Q and δy = ±0.5 x yo x P.

[0099] In the embodiments of the present disclosure, by using AI method to randomly generate the coordinates of the actual position of the isolation column according to the coordinates of the preset position of the isolation column, the isolation columns can be arranged in a non-periodic manner, thereby avoiding the problem of visual Mura caused by the stacking of the isolation column 1 and the display substrate.

[0100] The technical solutions of the present disclosure will be further described in combination with specific embodiments.

[0101] In some embodiments, preset positions of a plurality of isolation column groups are arranged on one side of a display panel. The display panel includes a plurality of pixel units arranged in multiple rows and multiple columns. A coordinate system is established, wherein the horizontal axis x of the coordinate system is parallel to the row direction of the pixel unit arrangement, and the vertical axis y is perpendicular to the row direction of the pixel unit arrangement.

[0102] In one example, each isolation column group includes seven isolation columns 1, specifically, the seven isolation columns 1 include six first isolation columns 11 and one second isolation column 12. The connecting line of the preset positions of the six first isolation columns 11 forms a regular hexagon, i.e. a regular hexagon, and the preset position of the second isolation column 12 is at the center of the regular hexagon. Moreover, the first side of the regular hexagon is parallel to the horizontal axis x of the coordinate system.

[0103] The coordinates (x, y) of the actual positions of the seven isolation columns 1 are generated based on (x, y) = (x' + δx, y' + δy), where δx = ±0.5 × xo × Q, δy = ±0.5 × yo × P, xo and yo are the side lengths of the square centered at the coordinates (x', y') of the preset positions of the seven isolation columns 1, and the coordinates (x, y) of the actual positions of the seven isolation columns 1 are randomly generated by using an AI algorithm, so as to generate the seven isolation columns.

[0104] Optionally, xo and yo can be set to 0.5 times the side length of a pixel unit.

[0105] Optionally, when the side length of a pixel unit is 150 um, xo and yo can be 90 um.

[0106] In this case, the seven isolation columns 1 in each isolation column group can form a random arrangement, and the isolation columns in the plurality of isolation column groups can form a non-fixed-period arrangement, so as to avoid the problem that the isolation columns and the display panel cause visual Mura after being mounted.

[0107] In another example, in order to better avoid the risk of visual Mura, the first side of the regular hexagon in the foregoing embodiment is rotated by a certain angle clockwise or counterclockwise to obtain the actual position of the isolation column.

[0108] Figure 7 is a plan view of the isolation column in still another embodiment of the present disclosure. Optionally, as shown in Figure 7 the first side of the regular hexagon in the foregoing embodiment is rotated by 15° clockwise. That is, the angle between the first side of the regular hexagon and the row direction of the pixel unit arrangement is 15°. It can be understood that the regular hexagon in the foregoing embodiment is rotated by 15° clockwise or counterclockwise as a whole. The embodiment of the present disclosure can further enable the actual position of the isolation column to have non-periodic irregularity, so as to avoid the problem that the isolation columns and the display panel cause visual Mura after being mounted.

[0109] In another example, each isolation column group includes four isolation columns 1, and the connecting line of the preset positions of the four isolation columns forms a regular quadrilateral, that is, a square. Meanwhile, the plurality of isolation column groups are arranged in multiple rows and multiple columns, and two isolation columns in the same row are shared by adjacent two isolation column groups, and two isolation columns in the same column are shared by adjacent two isolation column groups.

[0110] The isolation columns generated in the embodiment also form a non-periodic arrangement, and the problem that the isolation columns and the display panel cause visual Mura after being mounted can be avoided.

[0111] It is understood that the above embodiments are only exemplary for illustrating the principles of the present disclosure, and the present disclosure is not limited thereto. Various modifications and improvements can be made by those of ordinary skill in the art without departing from the spirit and essence of the present disclosure, and these modifications and improvements are also considered to be within the scope of protection of the present disclosure.
