Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a method for manufacturing a display panel. Background Art

[0002] Display panels are widely used in display devices such as mobile phones and tablets. With the improvement of display quality, people are placing increasingly higher demands on the screen-to-body ratio of display devices. One method to achieve a high screen-to-body ratio is to bend the display substrate in the display panel, bending the binding area of ​​the display substrate to the back side of the display area. This allows the flexible circuit board to be positioned on the non-display side of the display substrate, thereby increasing the display window area of ​​the display device, achieving a narrow bezel and a high screen-to-body ratio.

[0003] To prevent metal traces in the bend from breaking, a protective adhesive layer is typically applied to the surface of the bend. This protective adhesive layer is formed by curing a colloid. Due to the fluidity of the colloid, the cured protective adhesive layer has areas of uniform thickness and thinner areas at the edges. Reducing the size of the thinner areas would further enhance the narrowing of the bezel. Therefore, reducing the size of the thinner areas of the protective adhesive layer is a challenge that needs to be addressed. Summary of the Invention

[0004] Based on this, it is necessary to provide a method for manufacturing a display panel, aiming to reduce the size of the thinned area of ​​the protective adhesive layer.

[0005] According to one aspect of the present application, a method for manufacturing a display panel is provided, the method comprising:

[0006] Providing a flexible display substrate, the flexible display substrate comprising a display area and a non-display area, the non-display area comprising a to-be-bent area and a binding area;

[0007] Providing a colloid mixed with a magnetic substance, applying the colloid to the surface of the non-display area of ​​the flexible display substrate so that the colloid covers the area to be bent;

[0008] Providing a first magnetic device, and arranging the first magnetic device between the display area and the area to be bent, the first magnetic device being used to provide a first magnetic force that repels the magnetic material;

[0009] The colloid is solidified to form a protective adhesive layer.

[0010] The manufacturing method of the display panel in the embodiment of the present application is to mix a magnetic substance into the colloid, apply the colloid to the surface of the non-display area and make the colloid cover the area to be bent. At the same time, a first magnetic device that can repel the magnetic substance is set between the display area and the area to be bent of the flexible display substrate. Because the colloid has a certain fluidity, the colloid will gradually spread out. Since there is a first magnetic force of mutual repulsion between the first magnetic device and the magnetic substance, the first magnetic force will have a certain limiting effect on the diffusion of the colloid. Therefore, the protective adhesive layer formed after curing will have a reduced size of the thinned area close to the side of the first magnetic device. Furthermore, it is conducive to improving the level of narrow frame of the display panel.

[0011] In some embodiments, the step of providing a first magnetic device and disposing the first magnetic device between the display area and the area to be bent includes:

[0012] A first permanent magnet is provided, and the first permanent magnet is disposed between the display area and the area to be bent.

[0013] Using a first permanent magnet as the first magnetic element satisfies the requirement for providing a first magnetic force, thereby limiting the diffusion of the colloid and reducing the size of the thinned area of ​​the protective adhesive layer formed after curing. Furthermore, using a first permanent magnet as the first magnetic element offers the advantage of lower cost.

[0014] In some embodiments, the step of providing a first magnetic device and disposing the first magnetic device between the display area and the area to be bent includes:

[0015] A first electromagnet is provided and disposed between the display area and the area to be bent.

[0016] Using the first electromagnet as the first magnetic device satisfies the requirement for providing a first magnetic force, thereby limiting the diffusion of the colloid and reducing the size of the thinned area of ​​the protective adhesive layer formed after curing. Furthermore, using the first electromagnet as the first magnetic device allows the magnitude of the first magnetic force to be adjusted according to actual use, thereby facilitating better control of the size of the thinned area.

[0017] In some embodiments, after the step of providing the flexible display substrate, the manufacturing method further includes:

[0018] Providing a polarizing assembly, the polarizing assembly comprising a polarizer and a polarizer protective film, the polarizer being attached to the flexible display substrate and covering the display area;

[0019] The step of providing a first magnetic device and arranging the first magnetic device between the display area and the area to be bent includes:

[0020] A first magnetic device is provided, and the first magnetic device is disposed between the polarizing component and the area to be bent.

[0021] The first magnetic device is positioned between the polarizing element and the area to be bent. This allows for a certain distance between the protective adhesive layer formed after the colloid solidifies and the polarizing element. For products with fixed bends and straight panels, this allows the protective adhesive layer to completely avoid contact with the polarizer, thus avoiding adhesion between the protective adhesive layer and the polarizer protective film, and thus preventing the protective adhesive layer from being removed when the polarizer protective film is removed. For folding products, this not only reduces the size of the thinning area, but also satisfies the requirement for a buffer distance between the protective adhesive layer and the polarizer.

[0022] In some embodiments, the protective adhesive layer includes a uniform thickness region and a thinned region located around the uniform thickness region;

[0023] A dimension of the first magnetic component along a thickness direction of the flexible display substrate is greater than a thickness of the uniform thickness region.

[0024] The dimension of the first magnetic device along the thickness direction of the flexible display substrate is greater than the thickness of the uniform thickness area. This is conducive to ensuring that the range of action of the first magnetic force generated by the first magnetic device can cover the thickness range of the colloid, so as to effectively limit the diffusion of the colloid by utilizing the first magnetic force.

[0025] In some embodiments, after the step of applying the colloid to the surface of the non-display area of ​​the flexible display substrate so that the colloid covers the area to be bent, the manufacturing method further includes:

[0026] A second magnetic device is provided and arranged above the colloid, wherein the second magnetic device is used to provide a second magnetic force that repels the magnetic substance.

[0027] Under the action of the second magnetic force, the diffusion speed of the colloid is increased, and it is also beneficial to the discharge of bubbles inside the colloid, thereby improving the protective performance of the formed protective adhesive layer.

[0028] In some embodiments, the second magnetic device further includes a curing device for curing the coated colloid.

[0029] Therefore, by integrating the curing device into the second magnetic device, the colloid can be conveniently cured and formed.

[0030] In some embodiments, the step of providing a second magnetic device and placing the second magnetic device above the colloid includes:

[0031] A second permanent magnet is provided and disposed above the colloid.

[0032] Using a second permanent magnet as the second magnetic device can meet the requirement of providing a second magnetic force, thereby achieving the purpose of utilizing the second magnetic force to increase the diffusion speed of the colloid and expel bubbles inside the colloid. In addition, using a second permanent magnet as the second magnetic device also has the advantage of low cost.

[0033] In some embodiments, the step of providing a second magnetic device and placing the second magnetic device above the colloid includes:

[0034] A second electromagnet is provided and disposed above the colloid.

[0035] Using a second electromagnet as the second magnetic device satisfies the requirement for providing a second magnetic force, thereby utilizing the second magnetic force to increase the colloid diffusion rate and expel bubbles within the colloid. Furthermore, using a second electromagnet as the second magnetic device allows the magnitude of the second magnetic force to be adjusted based on usage requirements, thereby better controlling the colloid diffusion rate and improving the effectiveness of expelling bubbles within the colloid.

[0036] In some embodiments, the protective adhesive layer includes a uniform thickness region and a thinned region located around the uniform thickness region;

[0037] The orthographic projection of the second magnetic device on the flexible display substrate covers the orthographic projection of the uniform thickness region of the protective adhesive layer on the flexible display substrate.

[0038] This helps ensure that the second magnetic force generated by the second magnetic device covers the area where the colloid is located, so that the second magnetic force can effectively promote the diffusion of the colloid and discharge the bubbles in the colloid.

[0039] In some embodiments, after the step of applying the colloid to the surface of the non-display area of ​​the flexible display substrate so that the colloid covers the area to be bent, the manufacturing method further includes:

[0040] A third magnetic component is provided, and the third magnetic component is symmetrically arranged relative to the colloid and the first magnetic component. The third magnetic component is used to provide a third magnetic force that repels the magnetic substance.

[0041] That is to say, the third magnetic device is set in the binding area. Under the action of the third magnetic force provided by the third magnetic device, the protective glue layer formed by the solidification of the colloid will also have a reduced size in the thinned area close to the third magnetic device. In addition, the setting of the third magnetic device can also prevent the colloid from diffusing too much into the binding area under the action of the first magnetic force.

[0042] In some embodiments, the first magnetic device, the second magnetic device, and the third magnetic device are of an integrated design.

[0043] With such an arrangement, the first magnetic component, the second magnetic component and the third magnetic component can be installed in place at one time, which helps to save installation and adjustment time.

[0044] In some embodiments, the magnetic substance is magnetic powder.

[0045] Such an arrangement can make the colloid generate magnetism, so that the first magnetic force provided by the first magnetic device can act on the colloid.

[0046] In some embodiments, after the step of solidifying the colloid to form a protective adhesive layer, the manufacturing method further comprises:

[0047] The to-be-bent area is subjected to a bending process.

[0048] After the bending area of ​​the flexible display substrate is bent, the bending area becomes the bending area of ​​the display substrate, and the protective adhesive layer covers the bending area, thereby protecting the metal wiring in the bending area from breaking.

The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0055] When describing positional relationships, unless otherwise specified, when an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. Furthermore, when a layer is referred to as being "under" another layer, it can be directly under or one or more intervening elements may also be present.

These terms are only used to distinguish one element from another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this application.

[0059] Furthermore, in the specification, the phrase “planar distribution diagram” refers to a drawing when the target portion is viewed from above, and the phrase “cross-sectional diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0060] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0061] Display panels are widely used in display devices such as mobile phones and tablets. With the improvement of display quality, people have placed increasingly higher demands on the screen-to-body ratio of display devices. One method to achieve a high screen-to-body ratio is to bend the flexible display substrate 1 in the display panel so that the binding area 11 of the flexible display substrate 1 is bent toward the back side of the display area 12, thereby placing the flexible circuit board on the non-display side of the flexible display substrate. This can increase the display window area of ​​the display device, achieving a narrow bezel and a high screen-to-body ratio.

[0062] Please refer to Figure 1 In order to prevent the metal traces in the bending area 13 from breaking, a protective adhesive layer 2 is usually provided on the surface of the bending area 13. The protective adhesive layer 2 is formed by solidifying a colloid. Since the colloid has fluidity, the protective adhesive layer 2 formed after solidification has a uniform thickness area 21 and a thinning area 22 located at the edge. For the display panel, in order to ensure that the starting point of the area to be bent is subjected to less stress during bending, it is usually required that the uniform thickness area 21 of the protective adhesive layer exceeds the area to be bent by a certain distance, and the distance is usually greater than or equal to 150μm. Since this distance cannot be omitted, if the level of narrow frame of the display panel is to be improved, it is necessary to find ways to reduce the size of the thinning area 22 of the protective adhesive layer 2.

[0063] Related art fixed-curve straight-panel products (such as tablet phones) often use polarizer 3 as a barrier to reduce the size of thinned area 22 of protective adhesive layer 2. However, the colloid may diffuse and contact the polarizer protective film 4, causing adhesion to the polarizer protective film 4. This can cause the protective adhesive layer 2 to be removed along with the polarizer protective film 4, thereby increasing the risk of peeling of the protective adhesive layer 2.

[0064] However, in related art foldable products (such as mobile phone screens), a buffer distance is required between the protective adhesive layer 2 and the polarizer 3 to prevent the polarizer 3 and the flexible display substrate from misaligning during folding. Therefore, there is no effective way to reduce the size of the thinning area for foldable products.

[0065] In response to the above-mentioned problem, an embodiment of the present application proposes a method for manufacturing a display panel, which aims to reduce the size of the thinned area of ​​the protective adhesive layer.

[0066] Please refer to Figure 2 、 Figure 3 The method for manufacturing a display panel in an embodiment of the present application includes:

[0067] A flexible display substrate 100 is provided. The flexible display substrate 100 includes a display area 101 and a non-display area. The non-display area includes a to-be-bent area 102 and a binding area 103.

[0068] Providing a colloid 200, wherein a magnetic substance is mixed into the colloid 200;

[0069] Providing a first magnetic device 300 and disposing the first magnetic device 300 between the display area 101 and the to-be-bent area 102 , wherein the first magnetic device 300 is configured to provide a first magnetic force that repels the magnetic material;

[0070] Applying the colloid 200 on the surface of the non-display area of ​​the flexible display substrate 100 and making the colloid 200 cover the to-be-bent area 102;

[0071] The adhesive 200 is cured to form a protective adhesive layer 210 .

[0072] The manufacturing method of the display panel in the embodiment of the present application is to mix a magnetic substance into the colloid 200, apply the colloid 200 to the surface of the non-display area and make the colloid 200 cover the area to be bent 102, and at the same time, set the first magnetic device 300 that can repel the magnetic substance between the display area 101 and the area to be bent 102 of the flexible display substrate. Because the colloid 200 has a certain fluidity, the colloid 200 will gradually spread out. Since there is a first magnetic force of mutual repulsion between the first magnetic device 300 and the magnetic substance, the first magnetic force will form a certain restriction on the diffusion of the colloid 200. Therefore, the size of the thinned area 212 of the protective adhesive layer 210 formed after curing close to the side of the first magnetic device 300 will be reduced. In addition, it is conducive to improving the level of narrow frame of the display panel.

[0073] Furthermore, for fixed-bend straight-panel products, the display panel manufactured using the above-described manufacturing method can completely avoid contact between the protective adhesive layer 210 and the polarizer 410, thereby avoiding the problem of adhesion between the protective adhesive layer 210 and the polarizer protective film 420, and thus avoiding the problem of tearing off the protective adhesive layer 210 when removing the polarizer protective film 420. For foldable products, the display panel manufactured using the above-described manufacturing method can also completely avoid contact between the protective adhesive layer 210 and the polarizer 410, thereby achieving the purpose of reducing the size of the thinned area 212 and meeting the requirement of providing a buffer distance between the protective adhesive layer 210 and the polarizer 410.

[0074] In some embodiments, the step of providing a first magnetic device 300 and disposing the first magnetic device 300 between the display area 101 and the to-be-bent area 102 includes:

[0075] A first permanent magnet is provided and disposed between the display area 101 and the to-be-bent area 102 .

[0076] In this embodiment, the use of a first permanent magnet as the first magnetic device 300 satisfies the requirement for providing a first magnetic force, thereby utilizing the first magnetic force to restrict the diffusion of the colloid 200, thereby reducing the size of the thinned region 212 of the protective adhesive layer 210 formed after curing. Furthermore, the use of a first permanent magnet as the first magnetic device 300 also offers the advantage of lower cost.

[0077] In some other embodiments, the step of providing the first magnetic device 300 and disposing the first magnetic device 300 between the display area 101 and the to-be-bent area 102 includes:

[0078] A first electromagnet is provided and disposed between the display area 101 and the to-be-bent area 102 .

[0079] In this embodiment, the use of a first electromagnet as the first magnetic device 300 satisfies the requirement for providing a first magnetic force, thereby limiting the diffusion of the colloid 200 through the first magnetic force, thereby reducing the size of the thinned region 212 of the protective adhesive layer 210 formed after curing. Furthermore, the use of a first electromagnet as the first magnetic device 300 allows the magnitude of the first magnetic force to be adjusted according to actual use, thereby facilitating better control over the size of the thinned region 212.

[0080] In some embodiments, after providing the flexible display substrate 100, the manufacturing method further includes:

[0081] A polarizing assembly 400 is provided. The polarizing assembly 400 includes a polarizer 410 and a polarizer protective film 420. The polarizer 410 is attached to the flexible display substrate 100 and covers the display area 101.

[0082] The step of providing a first magnetic device 300 and disposing the first magnetic device 300 between the display area 101 and the to-be-bent area 102 includes:

[0083] A first magnetic device 300 is provided and disposed between the polarizing element 400 and the region to be bent 102 .

[0084] In this embodiment, the first magnetic device 300 is disposed between the polarizing assembly 400 and the to-be-bent region 102. This allows for a certain distance between the protective adhesive layer 210 formed after the colloid 200 solidifies and the polarizing assembly 400. For products such as fixed-bend straight panels, this allows for the protective adhesive layer 210 to be completely isolated from the polarizer 410, thereby avoiding adhesion between the protective adhesive layer 210 and the polarizer protective film 420. This, in turn, avoids the problem of tearing off the protective adhesive layer 210 when the polarizer protective film 420 is removed. For foldable products, this not only reduces the size of the thinned region 212, but also satisfies the requirement for providing a buffer distance between the protective adhesive layer 210 and the polarizer 410.

[0085] In some embodiments, the protective adhesive layer 210 includes a uniform thickness region 211 and a thinned region 212 located around the uniform thickness region 211 ;

[0086] The dimension of the first magnetic device 300 along the thickness direction of the flexible display substrate 100 is greater than the thickness of the uniform thickness region 211 .

[0087] In this embodiment, the dimension of the first magnetic device 300 along the thickness direction of the flexible display substrate 100 is greater than the thickness of the uniform thickness region 211. This facilitates the range of action of the first magnetic force generated by the first magnetic device 300 to cover the thickness range of the colloid 200, so as to effectively limit the diffusion of the colloid 200 by utilizing the first magnetic force.

[0088] In some embodiments, after applying the colloid 200 to the surface of the non-display area of ​​the flexible display substrate 100 and allowing the colloid 200 to cover the to-be-bent area 102 , the manufacturing method further includes:

[0089] A second magnetic device 500 is provided and disposed above the colloid 200 . The second magnetic device 500 is used to provide a second magnetic force that repels the magnetic substance.

[0090] In related art, the colloid 200 diffuses solely by its own weight, resulting in a slow diffusion rate and the formation of bubbles. In this embodiment, after the colloid 200 is applied to the surface of the flexible display substrate 100, a second magnetic device 500 is provided. The second magnetic device 500 is disposed above the colloid 200 and is used to provide a second magnetic force that repels the magnetic material. Under the action of this second magnetic force, the diffusion rate of the colloid 200 is increased, and it also facilitates the discharge of bubbles within the colloid 200, thereby improving the protective performance of the formed protective adhesive layer 210.

[0091] In some embodiments, the second magnetic device 500 further includes a curing device for curing the coated colloid 200 .

[0092] With this arrangement, the curing device is integrated into the second magnetic device, which can facilitate the curing and forming of the colloid.

[0093] Specifically, the curing device may be a light source for emitting ultraviolet light, and the ultraviolet light is used to irradiate the colloid 200 to cure the colloid into a shape.

[0094] In some embodiments, the steps of providing the second magnetic device 500 and placing the second magnetic device 500 above the colloid 200 include:

[0095] A second permanent magnet is provided and disposed above the colloid 200 .

[0096] In this embodiment, the second permanent magnet is used as the second magnetic device 500 to meet the requirement of providing a second magnetic force, thereby achieving the purpose of utilizing the second magnetic force to increase the diffusion speed of the colloid 200 and expel bubbles within the colloid 200. In addition, the use of the second permanent magnet as the second magnetic device 500 also has the advantage of low cost.

[0097] In some other embodiments, the steps of providing the second magnetic device 500 and placing the second magnetic device 500 above the colloid 200 include:

[0098] A second electromagnet is provided and disposed above the colloid 200 .

[0099] In this embodiment, the use of a second electromagnet as the second magnetic device 500 satisfies the requirement for providing a second magnetic force, thereby utilizing the second magnetic force to increase the diffusion rate of the colloid 200 and expel bubbles within the colloid 200. Furthermore, the use of a second electromagnet as the second magnetic device 500 allows the magnitude of the second magnetic force to be adjusted based on actual use, thereby better controlling the diffusion rate of the colloid 200 and facilitating the effective expulsion of bubbles within the colloid 200.

[0100] In some embodiments, the protective adhesive layer 210 includes a uniform thickness region 211 and a thinned region 212 located around the uniform thickness region 211 ;

[0101] The orthographic projection of the second magnetic device 500 on the flexible display substrate 100 covers the orthographic projection of the uniform thickness region of the protective adhesive layer 210 on the flexible display substrate 100 .

[0102] In this embodiment, the orthographic projection of the second magnetic device 500 on the flexible display substrate 100 covers the orthographic projection of the uniform thickness area of ​​the protective adhesive layer 210 formed after curing on the flexible display substrate 100. This helps to ensure that the range of action of the second magnetic force generated by the second magnetic device 500 can cover the area where the colloid 200 is located, so that the second magnetic force can be effectively used to promote the diffusion of the colloid 200 and discharge bubbles inside the colloid 200.

[0103] In some embodiments, after applying the colloid 200 to the surface of the non-display area of ​​the flexible display substrate 100 and allowing the colloid 200 to cover the to-be-bent area 102 , the manufacturing method further includes:

[0104] A third magnetic device 600 is provided and is symmetrically arranged with respect to the colloid 200 and the first magnetic member 300 . The third magnetic device 600 is used to provide a third magnetic force that repels the magnetic substance.

[0105] That is to say, the third magnetic device 600 is set in the binding area 103. Under the action of the third magnetic force provided by the third magnetic device 600, the protective glue layer 210 formed by the solidification of the colloid 200 will also have a reduced size in the thinned area 212 on the side close to the third magnetic device 600. In addition, the setting of the third magnetic device 600 can also prevent the colloid 200 from diffusing too much toward the binding area 103 under the action of the first magnetic force.

[0106] In some embodiments, the first magnetic device 300 , the second magnetic device 500 , and the third magnetic device 600 are integrally designed.

[0107] With such an arrangement, the first magnetic component 300 , the second magnetic component 500 and the third magnetic component 600 can be installed in place at one time, which helps to save installation and adjustment time.

[0108] In some embodiments, the magnetic substance is magnetic powder.

[0109] With such configuration, the colloid 200 can generate magnetism, so that the first magnetic force provided by the first magnetic device 300 can act on the colloid 200 .

[0110] In some embodiments, after the step of curing the colloid 200 to form the protective adhesive layer 210 , as shown in the figure, the manufacturing method further includes:

[0111] The bending area 102 is subjected to bending processing.

[0112] After the bending region 102 of the flexible display substrate 100 is bent, the bending region 102 becomes the bending region 102a of the flexible display substrate. Furthermore, the protective adhesive layer 210 covers the bending region, thereby protecting the metal traces in the bending region 102a from breakage.

[0113] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0114] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
