Implementation Method

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without requiring progressive changes are within the scope of protection of the present invention.

[0039] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0040] Figure 1 is a top view of the sealant, the opening in the sealant, and the blocking component of the liquid crystal panel. Figure 1 shows the structure of the liquid crystal panel during the liquid crystal filling stage.

[0041] As shown in Figure 1, the inventors of this invention discovered that a barrier 12 is provided in the sealant for liquid crystal panels with sizes ranging from 1 inch to 17 inches. This barrier 12 is offset from the inner edge of the sealant 11, specifically positioned at the liquid crystal filling opening 13 of the sealant 11, thereby slowing down the liquid crystal filling speed during the liquid crystal filling stage of the liquid crystal panel manufacturing process. However, this hinders the manufacture of liquid crystal panels with narrow bezels because it is difficult to control the size of the barrier 12 using dispensing methods, and the length L0 of the liquid crystal filling opening 13 is 1.0 mm to 3.0 mm. This length L0 is relatively large, which can generate air bubbles during the liquid crystal filling process and poses a risk of sealant overflow after liquid crystal filling.

[0042] Embodiments of the present invention provide a liquid crystal panel and a display device. The length of at least one liquid crystal filling opening in the frame structure of the liquid crystal panel in the liquid crystal flow cross-section is less than or equal to 0.8 mm.

[0043] Figure 2 is a cross-sectional schematic diagram of a liquid crystal panel according to an embodiment of the present invention; Figure 3 is a top view schematic diagram of the main body and the opening through the main body of the sealing frame structure of the liquid crystal panel according to an embodiment of the present invention; Figure 4 is a cross-sectional schematic diagram of the liquid crystal panel at the sealing frame structure according to an embodiment of the present invention. Figure 3 shows the structure of the liquid crystal panel during the liquid crystal filling stage.

[0044] As shown in Figures 2 to 4, for example, a liquid crystal panel 20 includes a first substrate 21, a second substrate 22 disposed opposite to each other, and a frame structure 23 disposed between the first substrate 21 and the second substrate 22. The frame structure 23 includes a main body 231 and at least one liquid crystal filling opening 232. The frame structure 23 is annular. The first substrate 21, the second substrate 22, and the frame structure 23 form a liquid crystal cell. The liquid crystal filling opening 232 penetrates the main body 231 of the frame structure 23. The liquid crystal filling opening 232 is configured to allow liquid crystal to flow into the liquid crystal cell during the liquid crystal filling stage. The length L of the liquid crystal filling opening 232 in the liquid crystal flow cross section is less than or equal to 0.8 mm.

[0045] In some embodiments, the enclosure structure 23 is in the form of a closed loop surrounding the liquid crystal cell. Although described as "ring-shaped" in some embodiments, the enclosure structure 23 is not limited to a circular ring and may have various geometries, including but not limited to rectangles (as shown in Figures 3, 5, and 7), squares, ellipses, or other polygons, depending on the desired shape of the liquid crystal panel. The shape of the enclosure structure 23 generally corresponds to the peripheral shape of the liquid crystal cell it encloses. For example, as shown in Figures 3 and 5, the enclosure structure 23 has a rectangular shape forming the perimeter of a rectangular liquid crystal cell. Regardless of its specific geometry, the enclosure structure 23 is configured to enclose liquid crystal within a liquid crystal cell formed between the first substrate 21 and the second substrate 22.

[0046] According to an embodiment of the present invention, since the length of the liquid crystal filling opening of the liquid crystal cell of the liquid crystal panel on the liquid crystal flow cross section is less than or equal to 0.8 mm, the filling speed of the liquid crystal can be controlled during the liquid crystal filling process of the liquid crystal panel, and the risk of generating liquid crystal filling bubbles and overflowing sealing glue after liquid crystal filling can be prevented.

[0047] The liquid crystal flow cross-section of the liquid crystal filling opening 232 refers to the cross-section of the liquid crystal filling opening 232 that allows liquid crystal to flow during the liquid crystal filling stage. As long as the liquid crystal filling opening 232 is provided, it has this liquid crystal flow cross-section, and it is not limited to being referred to as a liquid crystal flow cross-section only during the liquid crystal filling stage. The dimension of the liquid crystal filling opening 232 in the direction perpendicular to the liquid crystal flow cross-section is the depth of the liquid crystal filling opening 232.

[0048] In some embodiments, as shown in FIG3, the length L of the liquid crystal filling opening 232 in the liquid crystal flow cross section refers to the length of the liquid crystal filling opening 232 in the extension direction (e.g., direction X) of the side of the liquid crystal filling opening 232 on which the liquid crystal filling opening 232 is disposed. The length L of the liquid crystal filling opening 232 in the liquid crystal flow cross section shown in FIG3 is the dimension of the liquid crystal filling opening 232 in the direction X.

[0049] For example, the length of the liquid crystal filling opening 232 refers to its length L in the extension direction of the side of the liquid crystal panel 20 where the liquid crystal filling opening 232 is disposed, parallel to the main surface of the first substrate 21. The main surface of the first substrate 21 is, for example, the plane in the top view shown in FIG3, that is, the plane in the X and Y directions.

[0050] For example, as shown in Figures 3 and 4, the size (length L) of the orthographic projection of the liquid crystal injection opening 232 on the first substrate 21 is less than or equal to 0.8 mm.

[0051] For example, as shown in Figures 3 and 4, the size (length L) of the orthographic projection of the liquid crystal injection opening 232 on the second substrate 22 is less than or equal to 0.8 mm.

[0052] Figure 4 shows the length L and width W of the liquid crystal filling opening 232. Figure 4 illustrates the liquid crystal filling opening 232 as a rectangle. Of course, the shape of the liquid crystal filling opening 232 is not limited to that shown in Figure 4.

[0053] In some embodiments, as shown in FIG3, in order to facilitate liquid crystal filling, the length L of the liquid crystal filling opening 232 on the liquid crystal flow cross section is greater than or equal to 0.3 mm.

[0054] According to an embodiment of the present invention, since the length of the liquid crystal filling opening of the liquid crystal cell of the liquid crystal panel on the liquid crystal flow cross section is greater than or equal to 0.3 mm, the filling speed of the liquid crystal can be prevented from being too slow during the liquid crystal filling process of manufacturing the liquid crystal panel.

[0055] In some embodiments, in order to balance the liquid crystal filling speed, avoid the generation of air bubbles, and reduce the risk of sealant overflow, the size range of the liquid crystal filling opening 232 can be from 0.3 mm to 0.8 mm.

[0056] In some embodiments, as shown in FIG3, the main body 231 of the sealing frame structure 23 protrudes outward from the liquid crystal cell at the liquid crystal filling opening 232, so that the size of the liquid crystal flow channel at the liquid crystal filling opening 232 is larger than the size of the main body 231 in the direction perpendicular to its extension.

[0057] For example, as shown in FIG3, the dimension T of the liquid crystal filling opening 232 along the Y direction is greater than the length t of the body 231 of the sealing frame structure along the Y direction. For example, in some embodiments, the dimension T is greater than or equal to 2 mm.

[0058] According to an embodiment of the present invention, since the liquid crystal filling opening 232 protrudes outward from the liquid crystal cell, the size of the liquid crystal flow channel in the Y direction at the liquid crystal filling opening 232 is larger than the size of the main body in the Y direction. This ensures that the liquid crystal is smoothly filled into the liquid crystal cell during the liquid crystal filling stage, reduces leakage, facilitates liquid crystal filling, and thus improves production efficiency and yield.

[0059] FIG5 is a top view of the frame structure of the liquid crystal panel according to an embodiment of the present invention, and FIG6 is a cross-sectional view of the liquid crystal panel at the frame structure according to an embodiment of the present invention.

[0060] In some embodiments, as shown in FIG5, the sealing frame structure 23 further includes a sealing member 233, which is configured to seal the liquid crystal filling opening 232, so that the liquid crystal cell is a sealed cell. FIG5 shows a sealed cavity 66. A liquid crystal (not shown) is disposed in the sealed cavity 66. As shown in FIG5 and FIG6, the sealed cavity 66 is surrounded by a first substrate 21, a second substrate 22 and a sealing frame structure 23 located therebetween. A cross-section of the liquid crystal panel at the sealed cavity can be seen in FIG2.

[0061] Figures 5 and 6 show the structure of the liquid crystal panel after the liquid crystal filling opening 232 is sealed by the sealing member 233.

[0062] In some embodiments, the orthographic projection of the frame structure on the main surface illustrated in FIG5 is a rectangle, but the present invention is not limited thereto. The orthographic projection of the frame structure on the main surface can also be other shapes, such as a circle.

[0063] In some embodiments, the material of the seal 233 is a UV-curable adhesive.

[0064] In some embodiments, the sealant 233 may be formed by sealing the liquid crystal filling opening 232 after filling the liquid crystal cell with liquid crystal during the manufacturing process of the liquid crystal panel. Due to the size of the liquid crystal filling opening in the embodiments of the present invention, it is possible to prevent the sealant, such as sealing adhesive, from overflowing.

[0065] In some embodiments, the material of the seal 233 may also be other thermosetting adhesives, and the present invention does not limit this.

[0066] In some embodiments, the thickness of the liquid crystal cell ranges from greater than or equal to 3 micrometers to less than or equal to 60 micrometers. For example, the thickness of the liquid crystal cell refers to the height of the liquid crystal cell in the direction perpendicular to the main surface of the first substrate. Figure 2 shows the thickness TK of the liquid crystal cell.

[0067] FIG7 is a top view schematic diagram of a liquid crystal panel according to an embodiment of the present invention.

[0068] In some embodiments, the size of the liquid crystal cell is from 1 inch to 17 inches. Here, as shown in FIG7, the size of the liquid crystal cell refers to the diagonal length S of the display area of ​​the liquid crystal panel displaying the image.

[0069] In some embodiments, the size of the liquid crystal cell is 1 inch to 6 inches, and the number of liquid crystal filling openings 232 is one (not shown in the figure).

[0070] In some embodiments, the size of the liquid crystal cell is 6 inches to 17 inches, and the number of liquid crystal filling openings 232 is multiple.

[0071] In some embodiments, as shown in Figures 3-6, the number of liquid crystal filling openings is three. In this embodiment, the number of liquid crystal filling openings is not limited, and any number of liquid crystal filling openings can be made according to actual needs.

[0072] In some embodiments, as shown in Figures 3-6, a plurality of liquid crystal filling openings 232 are evenly distributed on one side of the liquid crystal cell.

[0073] According to an embodiment of the present invention, by uniformly distributing multiple liquid crystal filling openings on one side of the liquid crystal cell, it can be ensured that the liquid crystal is uniformly filled into the liquid crystal cell during the liquid crystal filling process, thereby reducing process time and improving product yield.

[0074] In some embodiments, as shown in FIG3, the liquid crystal filling opening 232 is configured to allow liquid crystal to pass through at its maximum flow cross-section. That is, during the liquid crystal filling process, the cross-sectional area of ​​the liquid crystal passing through the filling opening is the maximum flow area of ​​the filling opening, and the liquid crystal filling opening 232 is not blocked.

[0075] In some embodiments, as shown in FIG3, no obstruction is provided on the path for filling liquid crystal from the liquid crystal filling opening 232 into the liquid crystal cell.

[0076] According to an embodiment of the present invention, since the liquid crystal cell is not provided with a blocking element for slowing down the liquid crystal filling speed during the liquid crystal filling stage, the liquid crystal panel including the liquid crystal cell can have a narrow bezel, for example, the width of the narrow bezel on the main surface can be as narrow as 1.5 mm.

[0077] In some embodiments, the main material of the sealing frame structure is a sealing adhesive. For example, the sealing adhesive may be a UV-curable adhesive or other thermosetting adhesive.

[0079] As shown in Figures 8-11, embodiments of the present invention provide a method for manufacturing a liquid crystal panel, including:

[0080] Step S1: Fabricate the first substrate 21 and the second substrate 22, as shown in Figure 9. The first substrate can be a glass substrate, and the second substrate 22 can be a glass substrate.

[0081] Step S2: Apply sealant 24 to the first substrate 21 or the second substrate 22 and assemble the second substrate with the first substrate to form a seal structure 23 and a liquid crystal cell, as shown in Figures 10 and 11.

[0082] Referring back to Figure 3, as shown in Figure 3, the fabricated frame structure 23 includes a main body 231 and at least one liquid crystal filling opening 232. The liquid crystal filling opening 232 penetrates the main body 231 of the frame structure, and the length L of the liquid crystal filling opening 232 on the liquid crystal flow cross section is less than or equal to 0.8 mm.

[0085] In some embodiments, as shown in FIG3, the main body 231 of the frame structure 23 protrudes outward from the liquid crystal cell at the liquid crystal filling opening 232 so that the size T of the liquid crystal flow channel at the liquid crystal filling opening 232 is greater than the size t of the main body 231 in the direction perpendicular to its extension.

[0086] In some embodiments, the size of the liquid crystal cell is from 1 inch to 17 inches. The size of the liquid crystal cell refers to the diagonal length of the display area of ​​the liquid crystal panel in which the image is displayed.

[0091] In some embodiments, no obstruction is provided on the path through which liquid crystal is injected from the liquid crystal injection opening 232 into the liquid crystal cell.

[0092] According to an embodiment of the present invention, since no obstruction for slowing down the liquid crystal filling speed is provided in the liquid crystal cell of the liquid crystal panel, the sealing glue can be applied by either screen printing process or dispensing process, making the manufacturing method more flexible.

[0093] In some embodiments, after the first substrate and the second substrate are assembled into a cell, they are further subjected to hot pressing and cutting to form a liquid crystal cell.

[0094] In some embodiments, the liquid crystal filling process in step S3 includes: using a vacuum pump to evacuate the sealed cavity of the liquid crystal cell placed in a vacuum environment, which is formed by the first substrate, the second substrate and the sealing frame structure located therebetween, so that the sealed cavity forms a high vacuum state, and the vacuum pressure of the vacuum pump can be 1 Pa to 5 Pa; injecting liquid crystal from the liquid crystal injection opening into the sealed cavity until the entire display unit is filled, the liquid crystal filling time can be 60 minutes to 200 minutes, and the liquid crystal filling balancing time can be 30 minutes to 200 minutes; after the injection is completed, nitrogen gas is introduced to break the vacuum, and atmospheric pressure is used to assist the liquid crystal filling, and the vacuum breaking time can be 60 minutes to 200 minutes.

[0095] In some embodiments, after liquid crystal filling, the method provided by the embodiments of the present invention further includes sealing the liquid crystal filling opening 232 with a sealing adhesive and curing the sealing adhesive to form a sealing element (not shown in the figure) of the sealing frame structure. The sealing adhesive can be a UV-curable adhesive or other thermosetting adhesive. The material of the sealing element can be the same as or different from the material of the main body of the sealing frame structure.

[0096] In some embodiments, the liquid crystal panel can be cleaned after sealing and curing.

[0098] The present invention also provides a display device. The display device includes a liquid crystal panel according to any of the above embodiments.
