Detailed Description
The terms referred to in this application are explained first:
as shown in fig. 1, the viewing angle refers to an angle θ between a line of sight L1 and a perpendicular L0 of the display panel.
The large viewing angle means that the included angle theta between the line of sight L1 and the vertical line L0 of the display panel is in the range of 60-80 degrees.
The shading point is the intersection point of the emergent light which is just not shaded by the supporting component in the first sub-pixel or the second sub-pixel on the supporting column.
In the related art scheme, the display panel includes a pixel defining layer and a plurality of pixels disposed in the pixel defining layer, each of which may include red, green and blue sub-pixels, and the display panel may exhibit different colors and pictures by adjusting the brightness of the sub-pixels of different colors. In the manufacturing process, in order to keep a safe distance between the display panel and the mask (mask), a support column (SPC) needs to be disposed on a pixel defining layer between adjacent pixels, and generally, two adjacent sub-pixels of the same color are disposed asymmetrically with respect to the support column between the two pixels, so that the sub-pixels emit light in different directions and are blocked by the support column, which may cause directional viewing angle difference.
As shown in fig. 2 to 3, the display panel 10 includes a pixel defining layer 11 and a plurality of pixels disposed within the pixel defining layer 11, each of which includes a red sub-pixel 100, a green sub-pixel 200, and a blue sub-pixel 300.
A support column 400 is further disposed between the sub-pixels, where the support column 400 is disposed between two sub-pixels of the same color in the same column (two blue sub-pixels 300 are shown in fig. 3, and for convenience of description, two blue sub-pixels 300 are respectively defined as a first sub-pixel 310 and a second sub-pixel 320), and a distance D1 from a center of the first sub-pixel 310 to the support column 400 is closer than a distance D2 from a center of the second sub-pixel 320 to the support column 400, so that, in a case where theoretical light radiation ranges of the sub-pixels are substantially the same, since the first sub-pixel 310 is closer to the support column 400 and the second sub-pixel 310 is farther from the support column 400, an actual light radiation range of the first sub-pixel 310 is smaller than an actual light radiation range of the second sub-pixel 310, that is, an included angle θ1 between a virtual line of a center of the first sub-pixel 310 and a virtual line of the first light-shading point and a side surface of the first sub-pixel 310 away from the substrate is greater than an included angle θ2 between a virtual line of the center of the second sub-pixel 320 and a side surface of the second light-shading point and the second sub-pixel 320 away from the substrate; that is, when the display panel 10 is viewed at a large viewing angle, the amounts of light blocked by the support columns 400 by the first sub-pixels 310 and the second sub-pixels 320 are different, so that the viewing angle difference in different directions is caused, and the display effect of the display panel is affected. Note that, in the present application, the influence of the pixel defining layer 11 on the sub-pixel light emission is not considered, and only the influence of the support column 400 on the sub-pixel light emission is considered.
In view of this, the embodiments of the present application provide a display panel, a method for manufacturing the same, and a display device, in which a supporting component is disposed on a pixel defining layer between adjacent first and second sub-pixels, the supporting component includes a first supporting column and a second supporting column, so that when the display panel is observed at a large viewing angle in this direction, the amounts of light blocked by the supporting component by the first and second sub-pixels are the same, thereby reducing or eliminating the viewing angle difference of the display panel in different directions, and improving the display effect of the display panel.
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 4-11, the present embodiment provides a display panel 10, which includes a substrate, a pixel defining layer 11 disposed on one side of the substrate, and a plurality of sub-pixels disposed in the pixel defining layer 11; one of every two adjacent subpixels with the same color is a first subpixel 310, and the other is a second subpixel 320; a support assembly 500 is disposed on the pixel defining layer 11 between at least a portion of the adjacent first and second sub-pixels 310 and 320, the support assembly 500 including a first support column 510 and a second support column 520; along a first direction X, the support assembly 500 includes a first shading dot 501 adjacent to the first sub-pixel 310, and a second shading dot 502 adjacent to the second sub-pixel 320; an included angle θ1 between the virtual line of the center 311 of the first sub-pixel and the first shading point 501 and a side surface of the first sub-pixel 310 away from the substrate is equal to an included angle θ2 between the virtual line of the center 321 of the second sub-pixel and the second shading point 502 and a side surface of the second sub-pixel 320 away from the substrate.
Specifically, the display panel 10 of the present embodiment may include a substrate, a thin film transistor (Thin Film Transistor; TFT) layer, a planarization layer, an anode layer, a pixel defining layer 11, and a plurality of sub-pixels, a cathode layer, a polarizer, and an encapsulation layer within the pixel defining layer 11, which are stacked. As shown in fig. 4, the sub-pixels may include a red sub-pixel 100, a green sub-pixel 200, or a blue sub-pixel 300, and the plurality of sub-pixels are arranged in a plurality of columns in the first direction X, and adjacent columns are spaced apart along the second direction Y. For convenience of description, one of the two adjacent subpixels (illustrated as the blue subpixel 300 in fig. 4) having the same color in the first direction X is the first subpixel 310, and the other is the second subpixel 320, wherein the first direction X is parallel to a line connecting the centers 311 and 321 of the adjacent first and second subpixels.
A support assembly 500 is disposed on the pixel defining layer between at least one pair of adjacent first and second sub-pixels 310, 320. Referring to fig. 4 to 11, the support assembly 500 includes a first support post 510 and a second support post 520, and along a first direction X, the support assembly 500 includes a first shading point 501 near the first sub-pixel 310, and a second shading point 502 near the second sub-pixel 320, where an angle θ1 between a virtual line of the first shading point 501 and a center 311 of the first sub-pixel and a side surface of the first sub-pixel 310 away from the substrate is equal to an angle θ2 between a virtual line of the second shading point 502 and a side surface of the second sub-pixel 320 away from the substrate.
By the above scheme, the amounts of light rays blocked by the supporting component 500 from the first sub-pixel 310 and the second sub-pixel 320 are the same, so that the color cast phenomenon and the viewing angle difference of the display panel 10 under a large viewing angle can be reduced or eliminated, and the display effect of the display panel 10 is improved.
In one possible embodiment, the first support columns 510 and the second support columns 520 are arranged in the same layer, and the first support columns 510 and the second support columns 520 are arranged along the first direction X. Along the first direction X, the first support column 510 is disposed near the first sub-pixel 310, and the second support column 520 is disposed on a side of the first support column 510 away from the first sub-pixel 310.
Preferably, the first support column 510 and the second support column 520 are abutted to each other, or the first support column 510 and the second support column 520 are disposed at intervals.
In this embodiment, the height of the first support column 510 and the height of the second support column may be equal; alternatively, the height of the first support columns 510 may be greater than the height of the second support columns 520; alternatively, the height of the first support columns 510 may be less than the height of the second support columns 520; specifically, the setting can be performed as required. The first shading point 501 is located on the first support pillar 510, and the second shading point 502 is located on the second support pillar 520.
For example, as shown in fig. 5, the first support columns 510 and the second support columns 520 are each disposed on the pixel defining layer 11 and are disposed adjacently in the first direction X; the first support column 510 and the second support column 520 are located between the first sub-pixel 310 and the second sub-pixel 320. The first support column 510 and the second support column 520 are abutted against each other; the height of the first support column 510 is smaller than the height of the second support column 520; the first shading point 501 is located on the first support pillar 510, and the second shading point 502 is located on the second support pillar 520.
In the first direction X, the horizontal distance D1 of the first shading point 501 projected onto the center 311 of the first sub-pixel on the pixel defining layer is smaller than the horizontal distance D2 of the second shading point 502 projected onto the center of the second sub-pixel on the pixel defining layer. The vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate is smaller than the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate.
To ensure that the amount of light shielding of the first and second sub-pixels 310 and 320 by the support assembly 500 is consistent when the display panel 10 is viewed at a large viewing angle, the ratio between the vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate, and the horizontal distance D1 of the first light shielding point 501 projected onto the center 311 of the first pixel on the pixel defining layer along the first direction X is equal to the ratio between the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate, and the horizontal distance D2 of the second light shielding point 502 projected onto the center 321 of the second pixel on the pixel defining layer along the first direction X. That is, the included angle θ1 between the virtual line between the center 311 of the first sub-pixel and the first shading point 501 and the surface of the first sub-pixel 310 away from the substrate (i.e. the plane of the anode or the plane of the substrate) is equal to the included angle θ2 between the virtual line between the center 321 of the second sub-pixel and the second shading point 502 and the surface of the second sub-pixel 320 away from the substrate (i.e. the plane of the anode or the plane of the substrate).
In this embodiment, the materials of the first support column 510 and the second support column 520 may be the same or different. When the materials are the same, the two materials can be epoxy resin, acrylic resin or polyurethane base; or at least one of epoxy, acrylic or polyurethane based doped with thermally and/or photo-expandable particles. When the materials are different, the expansion coefficient of the first support column 510 may be smaller than that of the second support column 520; the material of the first support columns 510 may be epoxy, acrylic or polyurethane based, and the material of the second support columns 520 may be epoxy, acrylic or polyurethane based doped with thermal expansion particles and/or photo expansion particles.
By the above scheme, when the display panel 10 is viewed at a large viewing angle, the actual light radiation range of the first sub-pixel 310 is equal to the actual light radiation range of the second sub-pixel 320, that is, the amounts of light blocked by the supporting component 500 by the first sub-pixel 310 and the second sub-pixel 320 are the same, so that the color shift phenomenon and the viewing angle difference of the display panel 10 at the large viewing angle can be reduced or eliminated, and the display effect of the display panel 10 is improved.
As another example, as shown in fig. 6, the first support columns 510 and the second support columns 520 are disposed on the pixel defining layer 11 and are disposed adjacently in the first direction X; the first support column 510 and the second support column 520 are located between the first sub-pixel 310 and the second sub-pixel 320. The first support column 510 and the second support column 520 are abutted against each other; the height of the first support column 510 is equal to the height of the second support column 520; the first shading point 501 is located on the first support pillar 510, and the second shading point 502 is located on the second support pillar 520.
In the first direction X, the horizontal distance D1 of the first shading point 501 projected onto the center 311 of the first sub-pixel on the pixel defining layer is equal to the horizontal distance D2 of the second shading point 502 projected onto the center of the second sub-pixel on the pixel defining layer. The vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate is equal to the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate.
To ensure that the amount of light shielding of the first and second sub-pixels 310 and 320 by the support assembly 500 is consistent when the display panel 10 is viewed at a large viewing angle, the ratio between the vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate, and the horizontal distance D1 of the first light shielding point 501 projected onto the center 311 of the first pixel on the pixel defining layer along the first direction X is equal to the ratio between the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate, and the horizontal distance D2 of the second light shielding point 502 projected onto the center 321 of the second pixel on the pixel defining layer along the first direction X. That is, the included angle θ1 between the virtual line between the center 311 of the first sub-pixel and the first shading point 501 and the surface of the first sub-pixel 310 away from the substrate (i.e. the plane of the anode or the plane of the substrate) is equal to the included angle θ2 between the virtual line between the center 321 of the second sub-pixel and the second shading point 502 and the surface of the second sub-pixel 320 away from the substrate (i.e. the plane of the anode or the plane of the substrate).
In this embodiment, the materials of the first support column 510 and the second support column 520 are the same, and the materials of both may be epoxy resin, acrylic resin or polyurethane base; or may be an epoxy, acrylic or polyurethane base doped with thermally and/or photo-expandable particles.
By the above scheme, when the display panel 10 is viewed at a large viewing angle, the actual light radiation range of the first sub-pixel 310 is equal to the actual light radiation range of the second sub-pixel 320, that is, the amounts of light blocked by the supporting component 500 by the first sub-pixel 310 and the second sub-pixel 320 are the same, so that the color shift phenomenon and the viewing angle difference of the display panel 10 at the large viewing angle can be reduced or eliminated, and the display effect of the display panel 10 is improved.
As another example, as shown in fig. 7, the first support columns 510 and the second support columns 520 are disposed on the pixel defining layer 11 and are spaced apart in the first direction X; the first support column 510 and the second support column 520 are located between the first sub-pixel 310 and the second sub-pixel 320. The height of the first support column 510 is greater than the height of the second support column 520; the first shading point 501 is located on the first support pillar 510, and the second shading point 502 is located on the second support pillar 520.
In the first direction X, the horizontal distance D1 of the first shading point 501 projected onto the center 311 of the first sub-pixel on the pixel defining layer is larger than the horizontal distance D2 of the second shading point 502 projected onto the center of the second sub-pixel on the pixel defining layer. The vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate is greater than the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate.
To ensure that the amount of light shielding of the first and second sub-pixels 310 and 320 by the support assembly 500 is consistent when the display panel 10 is viewed at a large viewing angle, the ratio between the vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate, and the horizontal distance D1 of the first light shielding point 501 projected onto the center 311 of the first pixel on the pixel defining layer along the first direction X is equal to the ratio between the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate, and the horizontal distance D2 of the second light shielding point 502 projected onto the center 321 of the second pixel on the pixel defining layer along the first direction X. That is, the included angle θ1 between the virtual line between the center 311 of the first sub-pixel and the first shading point 501 and the surface of the first sub-pixel 310 away from the substrate (i.e. the plane of the anode or the plane of the substrate) is equal to the included angle θ2 between the virtual line between the center 321 of the second sub-pixel and the second shading point 502 and the surface of the second sub-pixel 320 away from the substrate (i.e. the plane of the anode or the plane of the substrate).
In this embodiment, the materials of the first support column 510 and the second support column 520 may be the same or different. When the materials are the same, they may be epoxy, acrylic or polyurethane based. When the materials of the two are different, the expansion coefficient of the first support column 510 may be greater than the expansion coefficient of the second support column 520; the material of the first support columns 510 may be epoxy, acrylic or polyurethane based doped with thermal expansion particles and/or photo expansion particles, and the material of the second support columns 520 may be epoxy, acrylic or polyurethane based.
By the above scheme, when the display panel 10 is viewed at a large viewing angle, the actual light radiation range of the first sub-pixel 310 is equal to the actual light radiation range of the second sub-pixel 320, that is, the amounts of light blocked by the supporting component 500 by the first sub-pixel 310 and the second sub-pixel 320 are the same, so that the color shift phenomenon and the viewing angle difference of the display panel 10 at the large viewing angle can be reduced or eliminated, and the display effect of the display panel 10 is improved.
In one possible embodiment, the first support columns 510 and the second support columns 520 are respectively disposed on a side of the pixel defining layer 11 remote from the substrate, and at least a portion of the second support columns 520 covers the first support columns 510.
Preferably, the second support columns 520 are stacked with the first support columns 510; along the first direction X, the first support pillar 510 is disposed adjacent to the first sub-pixel 310, a side of the first support pillar 510 away from the pixel defining layer 11 includes a first side adjacent to the first sub-pixel 310, and a second side adjacent to the second sub-pixel 320, and the second support pillar 520 is disposed adjacent to the second side.
In this embodiment, the first shading point 501 may be located on the first supporting column 510, and the second shading point 502 may be located on the second supporting column 520; alternatively, the first shading point 501 and the second shading point 502 may both be located on the second support column 520.
For example, as shown in fig. 8, the first support columns 510 and the second support columns 520 are disposed in different layers, the first support columns 510 are disposed on the pixel defining layer 11, and the second support columns 520 are stacked on the first support columns 510 and all located on a side of the first support columns 510 facing away from the pixel defining layer 11. The first support pillar 510 is disposed near the first sub-pixel 310, and a side of the first support pillar 510 away from the pixel defining layer 11 includes a first side near the first sub-pixel 310 and a second side near the second sub-pixel 320, and the second support pillar 520 is disposed near the second side, so as to facilitate shielding of light emitted from the second sub-pixel 320. The first shading point 501 is located on the first support pillar 510, and the second shading point 502 is located on the second support pillar 520.
In the first direction X, the horizontal distance D1 of the first shading point 501 projected onto the center 311 of the first sub-pixel on the pixel defining layer is smaller than the horizontal distance D2 of the second shading point 502 projected onto the center of the second sub-pixel on the pixel defining layer. The vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate is smaller than the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate.
To ensure that the amount of light shielding of the first and second sub-pixels 310 and 320 by the support assembly 500 is consistent when the display panel 10 is viewed at a large viewing angle, the ratio between the vertical distance H1 from the side surface of the first support column 510 away from the substrate to the side surface of the first sub-pixel 310 away from the substrate, and the horizontal distance D1 of the first light shielding point 501 projected onto the center 311 of the first pixel on the pixel defining layer along the first direction X is equal to the ratio between the vertical distance H2 from the side surface of the second support column 520 away from the substrate to the side surface of the second sub-pixel 320 away from the substrate, and the horizontal distance D2 of the second light shielding point 502 projected onto the center 321 of the second pixel on the pixel defining layer along the first direction X. That is, the included angle θ1 between the virtual line between the center 311 of the first sub-pixel and the first shading point 501 and the surface of the first sub-pixel 310 away from the substrate (i.e. the plane of the anode or the plane of the substrate) is equal to the included angle θ2 between the virtual line between the center 321 of the second sub-pixel and the second shading point 502 and the surface of the second sub-pixel 320 away from the substrate (i.e. the plane of the anode or the plane of the substrate).
In this embodiment, the materials of the first support column 510 and the second support column 520 are the same, and the materials of both may be epoxy, acrylic or polyurethane.

As another example, as shown in fig. 9, the first support columns 510 and the second support columns 520 are disposed in different layers, the first support columns 510 are disposed on the pixel defining layer 11, and the second support columns 520 are stacked on the first support columns 510 and all located on a side of the first support columns 510 facing away from the pixel defining layer 11. The first support pillar 510 is disposed near the first sub-pixel 310, and a side of the first support pillar 510 away from the pixel defining layer 11 includes a first side near the first sub-pixel 310 and a second side near the second sub-pixel 320, and the second support pillar 520 is disposed near the second side, so as to facilitate shielding of light emitted from the second sub-pixel 320. The first shading dot 501 and the second shading dot 502 are both located on the second support column 520.
In the first direction X, the horizontal distance D1 of the first shading point 501 projected onto the center 311 of the first sub-pixel on the pixel defining layer is equal to the horizontal distance D2 of the second shading point 502 projected onto the center of the second sub-pixel on the pixel defining layer. Since the first shading point 501 and the second shading point 502 are both located on the second supporting column 520, a vertical distance H1 from the first shading point 501 to a side surface of the first sub-pixel 310 away from the substrate is equal to a vertical distance H2 from the second shading point 502 to a side surface of the second sub-pixel 320 away from the substrate.

That is, the included angle θ1 between the virtual line between the center 311 of the first sub-pixel and the first shading point 501 and the surface of the first sub-pixel 310 away from the substrate (i.e. the plane of the anode or the plane of the substrate) is equal to the included angle θ2 between the virtual line between the center 321 of the second sub-pixel and the second shading point 502 and the surface of the second sub-pixel 320 away from the substrate (i.e. the plane of the anode or the plane of the substrate).
In this embodiment, the materials of the first support column 510 and the second support column 520 are the same, and the materials of both may be epoxy, acrylic or polyurethane.

In yet another possible implementation, a portion of the second support column 520 of the present example may cover the first support column 510.
Preferably, the second support columns 520 may be disposed to completely cover the first support columns 510; the first shading dot 501 and the second shading dot 502 are both located on the second support column 520.
For example, as shown in fig. 10, the first support columns 510 and the second support columns 520 are disposed on the pixel defining layer 11, and the first support columns 510 are covered at portions of the second support columns 520. The first support column 510 and the second support column 520 are located between the first sub-pixel 310 and the second sub-pixel 320. The first shading dot 501 and the second shading dot 502 are both located on the second support column 520.

That is, the included angle θ1 between the virtual line between the center 311 of the first sub-pixel and the first shading point 501 and the surface of the first sub-pixel 310 away from the substrate (i.e. the plane of the anode or the plane of the substrate) is equal to the included angle θ2 between the virtual line between the center 321 of the second sub-pixel and the second shading point 502 and the surface of the second sub-pixel 320 away from the substrate (i.e. the plane of the anode or the plane of the substrate).

In one possible implementation, the shape of the first support column 510 in this embodiment may be cylindrical, conical or frustum-shaped; the shape of the second support column 520 may be cylindrical, conical or frustoconical; the shape of the first support column 510 may be the same as or different from the shape of the second support column 520. Preferably, as shown in fig. 11, the first support column 310 has a right trapezoid shape in a cross section in a direction perpendicular to the display panel 10.
The embodiment also provides a display device, which comprises the display panel.
Specifically, the display device of the embodiment may be a mobile phone, a tablet computer, an electronic book, or a navigation device, and the display device has a housing, and an opening is provided on a surface of the housing, and a display panel is placed in the opening.
In this embodiment, the display panel is adopted, so that the viewing angle difference of the display panel in different directions can be reduced or eliminated, and the display effect of the display panel can be improved.
Referring to fig. 12, the present embodiment further provides a method for manufacturing a display panel, including:
step S101, providing a pixel limiting layer, wherein a plurality of sub-pixels are arranged in the pixel limiting layer; one of every two adjacent subpixels with the same color is a first subpixel, and the other subpixel is a second subpixel.
Specifically, the pixel defining layer is a film layer on the display panel, and a substrate, a thin film transistor layer, a planarization layer, an anode layer and other film layers are generally disposed below the pixel defining layer, and a related scheme in the prior art may be adopted in a process from the substrate to the pixel defining layer, which is not described in detail in this embodiment. A plurality of sub-pixels are arranged in the pixel limiting layer; one of every two adjacent subpixels with the same color is a first subpixel, and the other subpixel is a second subpixel. As shown in fig. 4, a plurality of sub-pixels are disposed in the pixel defining layer, and each sub-pixel may include a red sub-pixel 100, a green sub-pixel 200, or a blue sub-pixel 300, and the plurality of sub-pixels are arranged in a plurality of columns in the first direction X, and adjacent columns are spaced apart along the second direction Y. For convenience of description, one of the two adjacent subpixels (illustrated as the blue subpixel 300 in fig. 4) having the same color in the first direction X is the first subpixel 310, and the other is the second subpixel 320.
Step S102, a supporting component is arranged on a pixel limiting layer between at least part of adjacent first sub-pixels and second sub-pixels, and comprises a first shading point close to the first sub-pixels and a second shading point close to the second sub-pixels along a first direction;
the included angle between the virtual connecting line of the center of the first sub-pixel and the first shading point and the substrate is equal to the included angle between the virtual connecting line of the center of the second sub-pixel and the second shading point and the substrate.
Specifically, as shown in fig. 4 to 11, the support assembly 500 includes a first support post 510 and a second support post 520, and along a first direction X, the support assembly 500 includes a first light shielding point 501 near the first sub-pixel 310, and a second light shielding point 502 near the second sub-pixel 320, where an included angle θ1 between a virtual line connecting the center 311 of the first sub-pixel and the first light shielding point 501 and the substrate is equal to an included angle θ2 between a virtual line connecting the center 321 of the second sub-pixel and the second light shielding point 502 and the substrate, where the first light shielding point 510 and the second support post 520 are shielded from each other.
By the above scheme, the amounts of light rays blocked by the supporting component 500 from the first sub-pixel 310 and the second sub-pixel 320 are the same, so that the color cast phenomenon and the viewing angle difference of the display panel 10 under a large viewing angle can be reduced or eliminated, and the display effect of the display panel 10 is improved.
In this embodiment, the specific preparation method of the support assembly 500 may be selected according to the need.
For example, when preparing the display panel as shown in fig. 5, the expansion coefficients of the materials of the first support column 510 and the second support column 520 are different; specifically, the expansion coefficient of the material of the second support column is larger than that of the material of the first support column; the material of the second support column comprises thermally and/or photo-expandable particles. Alternatively, the material of the first support column is the same as the material of the second support column; the material of the first support post comprises at least one of an epoxy, an acrylic or a polyurethane base or comprises at least one of an epoxy, an acrylic or a polyurethane base doped with thermally and/or photo-expandable particles. The material of the first support column 510 may be epoxy, acrylic, or polyurethane based; the material of the second support columns 520 may be epoxy, acrylic or polyurethane based doped with thermally and/or photo-expandable particles. The coefficient of expansion of the material of the second support column 520 is greater than the coefficient of expansion of the material of the first support column 510.
The method of forming the plurality of support members 500 on the pixel defining layer includes:
A first support post material and a second support post material are coated on the pixel defining layer.
And obtaining a plurality of first support column blanks and a plurality of second support column blanks which are adjacently arranged through exposure, development and etching.
And baking and/or ultraviolet curing the first support column blanks and the second support column blanks to obtain the first support columns and the second support columns.
By adopting the scheme of the embodiment, the extra process of the display panel is not added, and the expansion particles in the second support column blank are expanded by using the baking or curing process after cleaning in the original process, so that the second support column is prepared.
When the display panel shown in fig. 8 is prepared, the materials of the first support columns 510 and the second support columns 520 may be epoxy, acrylic or polyurethane based.
The method of forming the plurality of support members 500 on the pixel defining layer 11 includes:
coating a first support column material on the pixel defining layer;
