Description

Display device and manufacturing method thereof

The invention relates to a display device and a manufacturing method thereof, and in particular to a display device suitable for coating a sealant and a manufacturing method thereof.

With the development of the display panel technology, it has been widely used in different fields and environments, for example, televisions, notebook computers, mobile phones, and wearable devices. In the field of wearable devices, in addition to satisfying the user's needs for the image quality and thinness of the display panel, in order to meet the needs of aesthetics and design, the display panel is designed to have a variety of different appearances, such as round, triangle, and diamond Other special-shaped structure.

At present, in the manufacturing process of the special-shaped display panel, the frame glue at the center of the panel must be coated by a specially designed machine, resulting in an increase in cost. However, the conventional coating process cannot uniformly set the frame glue, and it is easy to change the shape of the frame glue, resulting in an excessively large area, which affects the display range of the display area. In addition, after the frame glue is pressed onto the display panel, its shape is not easy to control, which further affects the display range and reduces the display quality.

The invention provides a manufacturing method of a display device, which is suitable for uniformly setting a frame glue layer, reducing the shape variation of the frame glue layer, and can simplify the manufacturing process and reduce the cost.

The invention provides a display device which can reduce the shape variation of the frame rubber layer and has a good display range and quality.

The manufacturing method of the display device of the present invention includes the following steps: providing a first substrate and a second substrate disposed opposite to the first substrate, the first substrate and the second substrate have a first non-display area and a display surrounding the first non-display area Area; forming a first pattern on the first substrate, and the first pattern is located in the first non-display area; setting a sealant layer on one of the first substrate or the second substrate, the sealant layer is located on the first non-display In the region and corresponding to the first pattern; pressing the first substrate to the second substrate; and, performing a hole-opening procedure in the first non-display area to remove part of the first substrate, part of the second substrate, part of the first pattern and part Frame glue layer.

In an embodiment of the invention, the method for manufacturing the display device further includes the following steps: forming a second pattern on the second substrate, the second pattern is located in the first non-display area, wherein the second pattern corresponds to the first pattern .

The display device of the present invention includes a first substrate and a second substrate disposed opposite to the first substrate, a first pattern is disposed on the first substrate, and a sealant layer is located between the first substrate and the second substrate. The first substrate and the second substrate have a first non-display area and a display area surrounding the first non-display area. The first substrate and the second substrate respectively have corresponding first openings and second openings in the first non-display area. At least part of the first pattern is located in the first non-display area and beside the first opening. Part of the sealant layer is located in the first non-display area and adjacent to the first pattern.

In an embodiment of the present invention, the above display device further includes a second pattern disposed on the second substrate, the second pattern is located in the first non-display area and beside the second opening, and the second pattern corresponds to the first pattern.

Based on the above, the display device and the manufacturing method thereof according to an embodiment of the present invention, because the first pattern is provided on the first substrate, and the first pattern has an uneven surface. In this way, the first convex portion can control the intensity and direction of dispersion of the sealant layer corresponding to the first pattern, so that the sealant layer gradually and uniformly diffuses into the display area, reducing shape variation of the sealant layer. Therefore, the frame layer does not need to be set through a specially designed machine, which can simplify the manufacturing process and reduce the cost. In addition, the probability of the glue layer extending into the display area after being pressed can be reduced without affecting the range of the display area, so the sealant layer can be further reduced and the size of the first opening and the second opening can be reduced to improve The overall display range and display quality of the display device can further improve the design margin of the display device.

In this way, each second convex portion 222 may be located between two adjacent first convex portions 124 and correspond to each first convex platform 122. Under the above arrangement, the first convex portion 124 and the second convex portion 222 may be arranged in a misaligned manner so that the first pattern 120 and the second pattern 220 form a complementary pattern. In this way, when the first substrate 100 is pressed to the second substrate 200, the first convex portion 124 of the first pattern 120 can effectively push and control the dispersion strength and the dispersion strength of the sealant layer 300 provided corresponding to the first pattern 120 In the direction, the sealant layer 300 is gradually and uniformly diffused from the second gap 226 toward the display area 14 along the second convex portion 222 to reduce the shape variation of the sealant layer 300. Therefore, the sealant layer 300 does not need to be set through a specially designed machine, which can simplify the manufacturing process and reduce the cost. In addition, since the sealant layer 300 is uniformly formed in the first non-display area 12, the probability of the sealant layer 300 extending into the display area 14 can be reduced without affecting the range of the display area 14. Therefore, the sealant layer 300 can be further reduced, improving the overall display range and display quality, and can further improve the design margin of the display area 14. In the above embodiment, each first convex portion 124 of the first pattern 120 corresponds to each second gap 226 of the second pattern 220, but it is not limited to this, in fact, each first convex portion 124 of the first pattern 120 may not correspond to For each second gap 226 of the second pattern 220, for example, each first convex portion 124 of the first pattern 120 may also correspond to each second convex portion 222 of the second pattern 220, or each first convexity of the first pattern 120 The portion 124 partially corresponds to each second gap 226 of the second pattern 220 and partially corresponds to each second convex portion 222. In addition, in the above embodiment, the plurality of first protrusions 122 form a grid-like structure, and the plurality of first protrusions 124 are located in the first gap 126 between the grids, but it is not limited to this. A plurality of first convex portions 124 may be formed in a grid-like structure, and the plurality of first bosses 122 are located in the first gap 126 between the grids.

In this embodiment, each first boss 122 has a first height H1, and each first convex portion 124 has a second height H2, and H2>H1. For example, the first height H1 is 2 μm to 3.7 μm, and the second height H2 is 3 μm to 4 μm, but the invention is not limited thereto. The difference between the second height H2 and the first height H1 may be that of the second height H2

Times. The second convex portion 222 has a third height H3, and H2-H1≥H3. For example, 0.3 μm≦H2-H1≦1 μm, and 0.3 μm≦H3≦1 μm, but the invention is not limited thereto. Under the above arrangement, the first convex portion 124 and the first boss 122 may form the first pattern 120 having an uneven surface, and the second convex portion 222 may also form the second pattern 220 having an uneven surface. The second convex portion 222 and the first convex portion 124 are misaligned, and the second convex portion 222 is disposed between the corresponding first boss 122 and the second substrate 200. In this way, it can be ensured that the sealant layer 300 provided corresponding to the first pattern 120 can be pushed and controlled by the first pattern 120 and the second pattern 220 having the uneven surface. Therefore, the sealant layer 300 can gradually and uniformly diffuse into the display area 14 to reduce the shape variation of the sealant layer 300. The probability of the sealant layer 300 extending into the display area 14 can be reduced without affecting the range of the display area 14. The sealant layer 300 located in the first non-display area 12 can be further reduced to improve the overall display range and display quality.

Finally, please refer to FIG. 3B and FIG. 4 to perform an opening process in the first non-display area 12 to remove part of the first substrate 100, part of the second substrate 200, part of the first pattern 120 and part of the sealant layer 300 to complete Production of the display device 10. In this embodiment, a part of the second pattern 220 is also removed by the hole-opening procedure. For example, the first substrate 100' and the second substrate 200' after the opening procedure have corresponding first openings 102 and second openings 202 in the first non-display area 12, respectively. In this embodiment, the width of the first opening 102 and the second opening 202 may be 2 mm to 4 mm, and the invention is not limited thereto. The drilling procedure includes tool drilling or laser drilling, but the invention is not limited to this. After the opening process is performed, the display device 10 forms a sealant layer 300 surrounding the first opening 102 and the second opening 202 in the first non-display area 12. For example, the shape of the sealant layer 300 in plan view may correspond to the shape of the first opening 102 and the second opening 202 in plan view, such as a circle, a triangle, a diamond, or a polygon. So far, the sealant layer 300 is completed in the first non-display area 12 of the display device 10.

In short, due to the manufacturing method of the display device 10 according to an embodiment of the present invention, the first pattern 120 may be provided on the first substrate 100 of the display motherboard 1 and the second pattern 220 may be provided on the second substrate 200. The pattern 120 corresponds to the second pattern 220 located in the first non-display area 12, and the first convex portion 124 and the second convex portion 222 may be arranged in a misaligned manner. Therefore, the concave and convex surfaces of the first pattern 120 and the second pattern 220 may form a complementary pattern. In this way, the first convex portion 124 can control the intensity and direction of the dispersion of the sealant layer 300 corresponding to the first pattern 120, so that the sealant layer 300 gradually and uniformly diffuses toward the display area 14, reducing the shape variation of the sealant layer 300 . Therefore, the sealant layer 300 does not need to be set through a specially designed machine, which can simplify the manufacturing process and reduce the cost. In addition, the probability that the glue layer 300 after being pressed into the display area 14 can be reduced without affecting the range of the display area 14, so the glue layer 300 can be further reduced to improve the overall display range and display quality. The design margin of the display area 14 can be improved.

In terms of structure, please refer to FIG. 4, the display device 10 of this embodiment includes a first substrate 100 ′, a second substrate 200 ′ disposed opposite to the first substrate 100 ′, and a first pattern 120 ′ disposed on the first substrate 100 ′ The upper and sealant layers 300 are located between the first substrate 100' and the second substrate 200'. The first substrate 100' and the second substrate 200' have a first non-display area 12 and a display area 14 surrounding the first non-display area 12. The first substrate 100' and the second substrate 200' have corresponding first openings 102 and second openings 202 in the first non-display area 12, respectively. At least part of the first pattern 120' is located in the first non-display area 12 and beside the first opening 102. For example, after the hole drilling process, a metal cutter (not shown) or laser (not shown) will remove part of the first boss 120 (shown in FIG. 3B) and the first protrusion 124 (shown in FIG. 3B ), and only a portion of the first boss 122 ′ remains in the first non-display area 12. In this embodiment, part of the sealant layer 300 is located in the first non-display area 12 and adjacent to the first pattern 120'.

In this embodiment, the first substrate 100' and the second substrate 200' of the display device 10 further have a second non-display area 16, the second non-display area 16 surrounds the display area 14, and a portion of the frame adhesive layer 300 is located in the second The non-display area 16 to form a space. The display medium layer LC is located in the display area 12 and between the first substrate 100 ′ and the second substrate 200 ′, and the sealant layer 300 in the first non-display area 12 and the second non-display area 16 surrounds the display medium layer LC .

In this embodiment, the second pattern 220' is disposed on the second substrate 200', and the second pattern 220' is located in the first non-display area 12 and beside the second opening 202. For example, the hole drilling process also removes part of the second convex part 222 (shown in FIG. 3B), leaving only part of the second convex part 222', and only part of the second convex part 222' in the first non-display District 12. In this embodiment, the second pattern 220' corresponds to the first pattern 120'.

In short, since the display device 10 according to an embodiment of the present invention can set the first pattern 120 on the first substrate 100 and the second pattern 220 on the second substrate 200 before the hole drilling process, the first pattern 120 corresponds to that the second pattern 220 is located in the first non-display area 12, and the first convex portion 124 and the second convex portion 222 may be disposed in a misaligned manner, for example. Therefore, the concave and convex surfaces of the first pattern 120 and the second pattern 220 may form a complementary pattern. In this way, the first convex portion 124 can control the intensity and direction of the dispersion of the sealant layer 300 corresponding to the first pattern 120, so that the sealant layer 300 gradually and uniformly diffuses toward the display area 14, reducing the shape variation of the sealant layer 300 . Therefore, the sealant layer 300 does not need to be set through a specially designed machine, which can simplify the manufacturing process and reduce the cost. In addition, the probability that the glue layer 300 after being pressed into the display area 14 can be reduced without affecting the range of the display area 14, so the glue layer 300 can be further reduced and the first opening 102 and the second opening can be reduced The size of the hole 202 improves the overall display range and display quality of the display device 10, and further improves the design margin of the display device 10.
