Further, the display panel 00 includes a cover plate 10, and an outer surface of the cover plate 10 includes the first surface 101.
The display panel 00 may be a liquid crystal display panel, an OLED (Organic Light-emitting diode) display panel, or other display panels. When the display panel 00 is used as a liquid crystal display panel, the display panel further includes a backlight plate, an array substrate, a liquid crystal layer and a color film substrate, and the cover plate 10 is arranged on the color film substrate to encapsulate the liquid crystal display panel; when the display panel 00 is used as an OLED display panel, the display panel further includes an array substrate and an OLED light-emitting layer, and the cover plate 10 is disposed on the OLED light-emitting layer to encapsulate the liquid crystal display panel. In summary, the first surface 101 is a surface of the cover plate 10 on a side away from the color film substrate or the OLED light emitting layer.

It can be understood that, since the first protection film 201 is directly formed on the first surface 101 by applying a liquid material at an early stage and curing the liquid material at a later stage, the lower surface of the first protection film 201 may completely coincide with the first surface 101, that is, the first protection film 201 may completely adhere to and cover the first surface 101, so that the first protection film 201 may prevent air or water vapor from entering the first surface 101, and may completely protect the entire first surface 101.
In one embodiment, the composition material of the first protective film 201 includes a resin or a rubber coating agent. It should be noted that the composition material of the first protection film 201 has a property that can assume a molten state or a solution state, so as to coat a liquid material corresponding to the composition material of the first protection film 201 on the first surface 101 to form the first protection film 201; further, the composition material of the first protection film 201 may include a more viscous material to improve the adhesion between the first protection film 201 and the first surface 101; still further, the first protection film 201 has a better strippable property, so that after some processes, the first protection film 201 can be stripped for subsequent packaging of the finished product.

It is understood that the thickness of the first protection film 201 in this embodiment is not less than 40 microns, the first surface 101 can be completely protected, and the thickness of the first protection film 201 in this embodiment is not more than 75 microns, so as to facilitate the later tearing of the first protection film 201 from the first surface 101. Specifically, the coating amount or the number of times of coating may be appropriately adjusted to form the first protection film 201 in a desired thickness, and for example, the amount of liquid spraying per unit time of the coating head may be increased or decreased, or coating and curing may be performed on the first surface 101 layer by layer so that the thickness of the first protection film 201 is in a desired thickness.
In other embodiments, on the premise of meeting the above requirements, other substances may be added to the composition material of the first protection film 201 according to other requirements, and the first protection film 201 meeting more requirements is formed by applying a liquid material in an early stage and curing the liquid material in a later stage. In other embodiments, on the premise of meeting the above requirements, according to other requirements, the first protective film 201 may be made of different materials on the first surface 101 layer by layer for pre-coating and post-curing, so as to form a composite film layer.
In an embodiment, as shown in fig. 2, unlike the embodiment of fig. 1, the cover plate 10 further includes a second surface 102, and the second surface 102 is a plane; the display panel 00 further includes a second protective film 202, and the second protective film 202 is disposed on the second surface 102.
The second surface 102 may be connected to the first surface 101, the first surface 101 and the second surface 102 have a contact line, the contact line is a straight line segment, a curved line segment, or the contact line is an initial connected line segment, and the first surface 101 and the second surface 102 may be connected to form a continuous surface.
In an embodiment, the second protection film 202 is a film layer formed by curing a liquid material coated on the second surface 102, and the second protection film 202 and the first protection film 201 are integrally formed. Wherein the second protective film 202 and the first protective film 201 may be uniform in composition material and thickness, and the first protective film 201 and the second protective film 202 may be formed by directly applying a corresponding liquid material on the first surface 101 and the second surface 102 without distinction.
Of course, when the requirements of the first protection film 201 and the second protection film 202 are different, or when there is another surface between the first surface 101 and the second surface 102, which results in non-continuity between the two, the corresponding liquid material may be coated on the first surface 101 and the corresponding liquid material may be coated on the second surface 102, and the second protection film 202 and the first protection film 201 are not integrally formed.
In one embodiment, the second protective film 202 is a film layer attached to the second surface 102. It can be understood that, since the second surface 102 is a plane, the second protection film 202 is directly attached to the flat second surface 102, and there is no problem of air bubbles or later falling between the second surface 102 and the second protection film 202. Meanwhile, the second protection film 202 may be prepared in advance, instead of being formed on the second surface 102, so the preparation manner of the second protection film 202 is not limited, and the composition material of the second protection film 202 may be the same as that of the first protection film 201, or the composition material of the second protection film 202 may be other materials with high viscosity and high film forming property, such as PET (polyethylene terephthalate).
In an embodiment, as shown in fig. 3, unlike the embodiment of fig. 1, the cover plate 10 further includes a third surface 103, where the third surface 103 is a curved surface; the display panel 00 further comprises a third protective film 203, wherein the third protective film 203 is disposed on the third surface 103.
Wherein the shapes and sizes of the third surface 103 and the first surface 101 may be the same or different, and the relative positions and arrangement of the third surface 103 and the first surface 101 may be referred to the above description of the relative positions and arrangement of the second surface 102 and the first surface 101. It can be understood that the third surface 103 is a curved surface, so that a corresponding liquid material can be coated on the third surface 103, and the third protection film 203 can be formed after curing, that is, the formation process of the third protection film 203 can be the same as the formation process of the first protection film 201. Further, when the third surface 103 and the second surface 102 are connected to form a continuous surface, and the third protection film 203 and the first protection film 201 may have the same composition material and thickness, the third protection film 203 and the first protection film 201 may be integrally formed, that is, the first protection film 201 and the third protection film 203 may be formed by directly coating the first surface 101 and the third surface 103 with corresponding liquid materials without distinction.
In an embodiment, as shown in fig. 4, unlike the embodiment of fig. 2, the cover plate 10 further includes a fourth surface 104, and the fourth surface 104 is a curved surface; the display panel 00 further includes a fourth protective film 204, and the fourth protective film 204 is disposed on the fourth surface 104.

It is understood that the fourth surface 104 is a curved surface, and thus, the forming process of the fourth protection film 204 may be the same as the forming process of the first protection film 201. Further, when the first surface 101, the second surface 102 and the fourth surface 104 are connected to form a continuous surface, and the composition materials and thicknesses of the fourth protection film 204, the second protection film 202 and the first protection film 201 can be consistent, the fourth protection film 204, the second protection film 202 and the first protection film 201 can be integrally formed, that is, the first surface 101, the second surface 102 and the fourth surface 104 can be directly coated with corresponding liquid materials without distinction to form the first protection film 201, the second protection film 202 and the fourth protection film 204.
The present invention provides a method for manufacturing a display panel as described in any of the above embodiments, including but not limited to the following embodiments.
In an embodiment, the manufacturing method of the display panel includes the steps shown in fig. 5.
S10, providing a cover plate, wherein the cover plate is provided with a first surface, and the first surface is a curved surface.
The display panel may be a liquid crystal display panel, an OLED (Organic Light-emitting diode) display panel, or other display panels. When the display panel is used as a liquid crystal display panel, the display panel further comprises a backlight plate, an array substrate, a liquid crystal layer and a color film substrate, wherein the cover plate is arranged on the color film substrate to encapsulate the liquid crystal display panel; when the display panel is used as an OLED display panel, the display panel further comprises an array substrate and an OLED light-emitting layer, and the cover plate is arranged on the OLED light-emitting layer to encapsulate the liquid crystal display panel. Thus, "providing a cover" may be understood as providing a display panel comprising a cover as an encapsulation structure for the display panel. In summary, the first surface is a surface of the cover plate on a side away from the color film substrate or the OLED light emitting layer.
The first surface may be a convex curved surface, a concave curved surface, or a continuous curved surface including a convex curved surface portion and a concave curved surface portion, and the specific shape of the first surface is not limited as long as the first surface is a curved surface.
S20, coating a liquid material on the first surface.
Specifically, the spraying includes, but is not limited to, the following ways: rolling over the first surface to apply the liquid material, for example using an applicator roll, which may be selected to be a smooth or anilox roll depending on the liquid material; for example, a coating brush is used for dipping the liquid material and coating the liquid material on the first surface, and the material of the coating brush can be selected according to the liquid material; then, for example, a sprayer is used to spray the liquid material on the first surface.
Wherein, the constituent material of the liquid material for coating on the first surface may refer to the above-mentioned description about the constituent material of the first protection film.
Wherein, the coating amount or the coating number of the liquid material may be set according to the thickness of the finally formed film layer, and the thickness of the finally formed film layer may be referred to the above related description about the thickness of the first protective film.
In one embodiment, the step S20 includes the following steps.
S201, dividing the first surface into a plurality of coating areas.
It can be understood that the coating head for spray coating has a region capable of covering each time the coating head coats the first surface, and here the first surface can be divided into a plurality of coating regions according to the coating range of the coating head, that is, the coating head can coat one of the coating regions each time.
S202, setting a corresponding target tangent plane according to the midpoint of each coating area, wherein the target tangent plane is a tangent plane at the midpoint of the coating area on the first surface.
It will be appreciated that the midpoint of each of the coated regions may represent a particular location of the coated region on the first surface. Further, since the target tangent plane corresponding to the midpoint of each coating region is a tangent plane at the midpoint of the coating region on the first surface, that is, the target tangent plane is tangent to the first surface, and the tangent point is the midpoint of the coating region.
S203, arranging the coating head perpendicular to the target section, and coating the liquid material on the coating area.
It will be appreciated that since the applicator head is arranged perpendicular to the target section, i.e. the applicator head can apply the coating to the midpoint of the coating area to form a circular coating area, with the center of the circle being the center of the coating area, it is ensured that each coating area is uniformly covered by the liquid material. The plurality of coating regions collectively constitute the first surface, so that the first surface can be uniformly covered with the liquid material, and the uniformity of coating is improved.
In one embodiment, the step S20 includes the following steps.
And S204, coating the liquid material on the first surface line by line along a preset direction, so that the first surface is uniformly covered by the liquid material.
The line-by-line indicates that each line has directionality, and the line-by-line indicates that a plurality of lines are arranged one by one along the preset direction, and the coating head for coating has a certain size, so that after one line of coating is completed, a certain-size area on the first surface is covered, and in the process of coating the liquid material, the edges of the areas corresponding to two adjacent lines are ensured to be exactly overlapped, so that the first surface is uniformly covered by the liquid material, and the uniformity of coating is improved.
In one embodiment, the step S204 includes the following steps.
S2041, coating a liquid material from any point on any edge of the first surface along a first path to any point on the other edge of the first surface to form a first sub-protective film.
The first path may be a straight line segment or a curved line segment, and the first path may be relatively parallel to one edge of the first surface as long as two end points of the first path are respectively located on two different edges of the first surface.
Specifically, as shown in fig. 6, the edge of the first surface 101 includes a plurality of straight or curved line segments. For example, the coating head can be moved from point 011 on edge 01 of the first surface 101 along the first path 11 to coat the liquid material up to point 041 on the other edge 04 of the first surface 101 to form a first sub-protective film 21. For another example, the coating head may be moved from a point 012 on the edge 01 of the first surface 101 along a first path 12 to coat the liquid material to a point 032 on the other edge 03 of the first surface 101 to form a first sub-protection film 22, wherein the first path 12 may coincide with the edge 02 of the first surface 101.
S2042, sequentially forming a plurality of first sub-protective films on the first surface along a second path, where an interval between two adjacent first sub-protective films is zero.
And defining the second path as a path formed by connecting the midpoints of the plurality of first sub-protective films, wherein the second path is a straight line segment formed by intersecting the perpendicular bisector of the corresponding first path and the first surface.
Specifically, as shown in fig. 6, for example, in the case of the first sub-protection films 21, the second path 13 is a straight line segment formed by intersecting a perpendicular bisector of the first path 11 with the first surface 101, and a plurality of the first sub-protection films 21 are sequentially formed on the first surface 101 along the second path 13, it can be understood that, due to the limitation of the edge of the first surface 101, the lengths of the plurality of first sub-protection films 21 along the first path 11 are not equal, and further, the interval between two adjacent first sub-protection films 21 is zero, so that the first surface 101 is completely covered by the liquid material. For another example, in the first sub-protection films 22, similarly, the second path 14 is a straight line segment formed by intersecting the perpendicular bisector of the first path 12 with the first surface 101, the plurality of first sub-protection films 22 are sequentially formed on the first surface 101 along the second path 14, and the interval between two adjacent first sub-protection films 22 is zero, and it can be understood that since the first path 12 is parallel to and equal to the edge 02, the plurality of first sub-protection films 22 are identical in shape and size when the edge 04 is parallel to and equal to the edge 02, the edge 01 is parallel to and equal to the edge 03, and both the edge 01 and the edge 03 are straight line segments.
And S30, solidifying the liquid material on the first surface to form a first protective film attached to the first surface.
The curing can be air oxidation curing, solvent volatilization curing, thermal reaction or chemical reaction curing, radiation curing or infrared catalysis thermal reaction curing, wherein the first protective film is formed by the first two curing modes at room temperature, and the curing speed is low; therefore, the first protective film can be formed by radiation curing, for example, when the liquid material contains a photoinitiator or other similar substances, the liquid material can be cured by ultraviolet light, the light wave of the ultraviolet light is 300-400nm, the liquid material containing the photoinitiator generates radicals under the irradiation of the ultraviolet light, and the radicals initiate the unsaturated monomer or resin to undergo a polymerization reaction, so that the dried first protective film can be cured within a few seconds to a few minutes.
As can be understood, since the first protection film is directly formed on the first surface by way of applying a liquid material at an early stage and curing the liquid material at a later stage, the lower surface of the first protection film may completely coincide with the first surface, that is, the first protection film may completely adhere to and cover the first surface; air or water vapour can be prevented from entering the first surface and the entire first surface can be completely protected.
The invention provides a display panel and a manufacturing method thereof, wherein the display panel is provided with a first surface with a curved surface, and a first protective film which is attached to the first surface is formed by coating a liquid material on the first surface, so that the first protective film can protect the first surface with the curved surface in the display panel, and the risk that the curved surface area of the display panel is scratched or corroded in later manufacturing is reduced.
The display panel and the manufacturing method thereof provided by the embodiment of the invention are described in detail, a specific example is applied in the description to explain the principle and the implementation of the invention, and the description of the embodiment is only used to help understanding the technical scheme and the core idea of the invention; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
