Description

Technical Field

[0001] The embodiments of the present application relate to the field of display technology, and in particular, to a display device. Background Art

[0002] A display device is a common electronic output device that can convert electronic files into graphics. The display device includes a housing and a display panel. The backlight side of the display panel is connected to the housing, and a protective film is provided on the light-emitting side of the display panel to play a role in polarization and protection.

[0003] However, when the display device is shaken due to external forces or other factors, the protective film is prone to warping, bubbles are prone to form between the protective film and the display panel, and film prints are prone to appear on the display panel. Utility Model Content

[0004] The embodiments of the present application provide a display device that can solve technical problems such as the edge warping of the protective film, bubbles being generated between the protective film and the display panel, and film printing being easily generated on the display panel.

[0005] In a first aspect, an embodiment of the present application provides a display device, including:

[0006] chassis;

[0007] A display panel, wherein a backlight side of the display panel is connected to the housing, a light-emitting side of the display panel faces away from the housing, and a protective film is provided on the light-emitting side of the display panel;

[0008] The protective tape comprises a first adhesive portion, a second adhesive portion and an extension portion; the first adhesive portion is adhesively fixed to a surface of the protective film away from the display panel, and the first adhesive portion is located on the inner side of the protective film; the second adhesive portion is adhesively fixed to the housing, and the second adhesive portion is located on the outer side of the protective film;

[0009] The extension portion extends from the inner side of the protective film through the edge of the protective film to the outer side of the protective film, the first end of the extension portion is connected to the first adhesive portion, and the second end of the extension portion is connected to the second adhesive portion.

[0010] The display device of the embodiment of the present application is provided with a protective tape connecting the protective film and the casing, and the protective tape includes a first adhesive portion, a second adhesive portion and an extension portion that are connected to each other; the first adhesive portion is bonded and fixed to the protective film, the second adhesive portion is bonded and fixed to the casing, and the extension portion extends from the inner side of the protective film through the edge of the protective film to the outer side of the protective film, and at least a portion of the extension portion can be directed toward the edge of the protective film.

[0011] When the display device shakes due to external forces or other factors, relative movement may occur between the display panel and the housing, and the housing may apply a pulling force to the first adhesive portion through the extension portion. The housing applies a first pulling force to the first adhesive portion through the extension portion, and the first pulling force may deviate from the display panel along the thickness direction of the display panel. The extension portion may be separated from the protective film, and the extension portion is spaced apart from the edge of the protective film, so that the first adhesive portion and the second adhesive portion do not contact the edge of the protective film, thereby reducing the possibility that the first adhesive portion drives the edge of the protective film to separate from the display panel.

[0012] And / or, the casing applies a second pulling force to the first adhesive portion through the extension portion, and the direction of the second pulling force is toward the outside of the protective film. The extension portion is in sliding contact with the protective film, thereby reducing the relative sliding between the protective film and the display panel caused by the protective tape, reducing the possibility of the protective film warping, reducing the possibility of bubbles forming between the protective film and the display panel, thereby reducing the possibility of film printing on the display panel.

[0013] In some embodiments of the present application, the distance between the first adhesive portion and the edge of the protective film is greater than or equal to 5 mm and less than or equal to 15 mm.

[0014] In this way, the distance between the first adhesive portion and the edge of the protective film is greater than or equal to 5 mm and less than or equal to 15 mm, thereby reducing the possibility of the first adhesive portion coming into contact with the edge of the protective film. When the casing applies a first pulling force to the first adhesive portion through the extension portion, the distance between the first adhesive portion and the edge of the protective film is greater than or equal to 5 mm, which can reduce the possibility of the protective film warping due to the protective tape.

[0015] In some embodiments of the present application, in the extension direction of the protective tape, the length of the first adhesive portion is greater than or equal to 20 mm, and the length of the second adhesive portion is greater than or equal to 20 mm;

[0016] And / or, in the extension direction of the protective tape, the length of the extension portion is greater than or equal to 15 mm.

[0017] In this way, the length of the first adhesive portion is greater than or equal to 20 mm, and the length of the second adhesive portion is greater than or equal to 20 mm, thereby improving the stability of the bonding between the first adhesive portion and the protective film, and the second adhesive portion and the casing, and reducing the possibility of detachment of the first adhesive portion and the second adhesive portion.

[0018] And / or, when relative movement occurs between the housing and the display panel, the extension portion can produce a certain deformation, so that a certain buffering effect can be played by the extension portion, and the length of the extension portion is greater than or equal to 15 mm, thereby reducing the pulling force of the housing on the display panel.

[0019] In some embodiments of the present application, the extension portion has a smooth surface facing the protective film, and the extension portion is in smooth contact with a surface of the protective film facing away from the display panel through the smooth surface.

[0020] In this arrangement, the casing applies a second pulling force to the first adhesive portion through the extension portion, and the direction of the second pulling force is toward the outside of the protective film. The extension portion is in smooth contact with the surface of the protective film facing away from the display panel through the smooth surface, thereby reducing the friction between the extension portion and the protective film, and reducing the possibility of relative movement between the protective film and the display panel.

[0021] In some embodiments of the present application, the housing includes a middle frame, and the middle frame includes a middle frame body and a middle frame outer edge connected to each other;

[0022] The middle frame body is connected to the backlight side of the display panel;

[0023] The middle frame outer edge is arranged on the outer side of the middle frame body, and the middle frame outer edge extends toward the front side of the middle frame body; the inner surface of the middle frame outer edge is spaced apart from the display panel, and the middle frame outer edge is bonded and fixed to the second bonding portion.

[0024] With such a configuration, the middle frame body can be used to connect the display panel, and the outer edge of the middle frame can provide a certain limit protection for the display panel, thereby reducing the possibility of damage to the display panel due to collision. The outer edge of the middle frame is bonded and fixed to the second adhesive portion, thereby achieving connection of the protective tape through the outer edge of the middle frame.

[0025] In some embodiments of the present application, in the thickness direction of the display panel, an end of the outer edge of the middle frame away from the middle frame body is protruded relative to the protective film;

[0026] In a direction from the protective film to the outer edge of the middle frame, the extending portion gradually moves away from the protective film, and the extending portion is spaced apart from an edge of the protective film.

[0027] With this arrangement, in the thickness direction of the display panel, one end of the outer edge of the middle frame away from the middle frame body is protruded relative to the protective film, and the extension portion is spaced apart from the edge of the protective film, thereby reducing the possibility of contact between the extension portion and the protective film.

[0028] When the housing applies the second pulling force to the first bonding portion through the extension portion, the extension portion is spaced apart from the edge of the protective film so that the extension portion does not contact the protective film, thereby reducing the possibility of the extension portion driving the protective film and the display device to move relative to each other.

[0029] In some embodiments of the present application, the second end of the extension portion is located outside the outer edge of the middle frame;

[0030] The first portion of the second adhesive portion is adhesively bonded to the outer side surface of the outer edge of the middle frame, and the second portion of the second adhesive portion is adhesively bonded to the surface of the middle frame body facing away from the display panel.

[0031] In this way, the first part of the second adhesive portion is bonded to the outer side surface of the middle frame, and the second part of the second adhesive portion is bonded to the surface of the middle frame body facing away from the display panel, thereby increasing the contact area between the second adhesive portion and the casing, making the connection between the second adhesive portion and the casing more stable.

[0032] In some embodiments of the present application, the housing includes a back panel, and the back panel includes a back panel body, a back panel side, and a fitting portion;

[0033] The back panel side edge is arranged around the outer side of the back panel body; in the thickness direction of the display panel, the first end of the back panel side edge is connected to the back panel body, the second end of the back panel side edge extends toward the front side of the back panel body, and the outer side surface of the back panel side edge is bonded and fixed to the second bonding portion;

[0034] The bonding portion is connected to the second end of the back panel side, and the bonding portion is arranged on the inner side of the back panel side; the bonding portion is spaced apart from the back panel body, and the surface of the bonding portion facing away from the back panel body is connected to the display panel.

[0035] In this way, the side edge of the back plate is arranged around the outside of the back plate body, so that the display panel can be supported and protected by the side edge of the back plate. The bonding part is arranged at a distance from the back plate body, and the surface of the bonding part away from the back plate body is connected to the display panel, so that the display panel can be connected to the back plate.

[0036] In some embodiments of the present application, the side edge of the back panel is located outside the display panel;

[0037] A protrusion is arranged on the surface of the fitting portion away from the back plate body, and the protrusion is located outside the display panel;

[0038] The first portion of the extending portion is in smooth contact with the surface of the protective film facing away from the display panel, and the second portion of the extending portion is in smooth contact with the protrusion.

[0039] In this arrangement, the first part of the extension is in smooth contact with the surface of the protective film facing away from the display panel, and the second part of the extension is in smooth contact with the protrusion, so that the protrusion can provide a certain support to the extension, thereby reducing the possibility of the extension directly contacting the edge of the protective film and reducing the movement of the edge of the protective film driven by the extension, thereby reducing the possibility of the protective film warping and the possibility of bubbles forming between the protective film and the display panel.

[0066] As described in the background art, the display device in the related art includes a housing and a display panel. The backlight side of the display panel is connected to the housing, and a protective film is provided on the light output side of the display panel to play the role of polarization and protection.

[0067] The display device is usually also provided with a protective tape. The first end of the protective tape is bonded and fixed to the protective film, the second end of the protective tape extends to the housing through the edge of the protective film, and the second end of the protective tape is bonded and fixed to the housing, so as to improve the connection stability between the housing and the display panel through the protective tape.

[0068] However, when the display device shakes due to external forces or other factors, the display panel and the housing may move relative to each other, and the housing applies tension to the protective tape. When the tension applied by the housing to the protective tape moves away from the display panel along the thickness direction of the display panel, the protective film is easily warped due to the edge of the protective film being bonded and fixed to the protective tape, which makes it easy for bubbles to form between the protective film and the display panel, and the display panel is prone to film printing.

[0069] When the pulling force applied by the casing to the protective tape is toward the outside of the protective film, since the edge of the protective film is bonded and fixed to the protective tape, the protective film is easily moved relative to the display panel under the drive of the protective tape, and a gap is easily generated between the protective film and the display panel, which makes it easy for bubbles to be generated between the protective film and the display panel, and the display panel is prone to film printing and other phenomena.

[0070] In view of this, the display device of the embodiment of the present application is provided with a protective tape connecting the protective film and the casing, and the protective tape includes a first adhesive portion, a second adhesive portion and an extension portion that are connected to each other; the first adhesive portion is bonded and fixed to the protective film, the second adhesive portion is bonded and fixed to the casing, and the extension portion extends from the inner side of the protective film through the edge of the protective film to the outer side of the protective film, and at least part of the extension portion can be facing the edge of the protective film.

[0071] When the display device shakes due to external forces or other factors, relative movement may occur between the display panel and the housing, and the housing may apply a pulling force to the first adhesive portion through the extension portion. The housing applies a first pulling force to the first adhesive portion through the extension portion, and the first pulling force may deviate from the display panel along the thickness direction of the display panel. The extension portion may be separated from the protective film, and the extension portion is spaced apart from the edge of the protective film, so that the first adhesive portion and the second adhesive portion do not contact the edge of the protective film, thereby reducing the possibility that the first adhesive portion drives the edge of the protective film to separate from the display panel.

[0072] And / or, the casing applies a second pulling force to the first adhesive portion through the extension portion, and the direction of the second pulling force is toward the outside of the protective film. The extension portion is in sliding contact with the protective film, thereby reducing the relative sliding between the protective film and the display panel caused by the protective tape, reducing the possibility of the protective film warping, reducing the possibility of bubbles forming between the protective film and the display panel, thereby reducing the possibility of film printing on the display panel.

[0073] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0079] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0080] Reference Figure 1-Figure 3 The embodiment of the present application provides a display device, including a housing 100 and a display panel 200. The backlight side of the display panel 200 can be connected to the front side of the housing 100 to fix the display panel 200 through the housing 100. The light-emitting side of the display panel 200 can be away from the housing 100, and a protective film 210 can be provided on the light-emitting side of the display panel 200 to play the role of polarization and protection through the protective film 210.

[0081] The display device may include a protective tape 300. The protective tape 300 may be used to at least connect the housing 100 and the display panel 200 to improve the stability of the connection between the housing 100 and the display panel 200. For example, during the production and transportation of the display device, when the display device is shaken by external forces, the protective tape 300 can reduce the possibility of relative movement between the housing 100 and the panel.

[0082] Exemplarily, the protective tape 300 may include a first adhesive portion 310, a second adhesive portion 330, and an extension portion 320. The first adhesive portion 310 may be bonded and fixed to the surface of the protective film 210 away from the display panel 200, and the first adhesive portion 310 may be located on the inner side of the protective film 210. The second adhesive portion 330 may be bonded and fixed to the housing 100, and the second adhesive portion 330 may be located on the outer side of the protective film 210.

[0083] The extension portion 320 may extend from the inner side of the protective film 210 through the edge of the protective film 210 to the outer side of the protective film 210. The first end of the extension portion 320 may be connected to the first adhesive portion 310, and the second end of the extension portion 320 may be connected to the second adhesive portion 330. The first adhesive portion 310 and the second adhesive portion 330 may be relatively fixed by the extension portion 320.

[0084] During the production and transportation of the display device, when the display device shakes due to external forces or other factors, relative movement may occur between the display panel 200 and the casing 100. Since the casing 100 is connected to the protective film 210 of the display panel 200 through the protective tape 300, the casing 100 can apply a pulling force to the first adhesive portion 310 through the extension portion 320 of the protective tape 300.

[0085] Exemplarily, the tension can be regarded as the resultant force of the first tension and the second tension, that is, the tension can be decomposed into the intersecting first tension and the second tension. The first tension (i.e., the tension parallel to the y direction in the figure) can be away from the display panel 200 along the thickness direction of the display panel 200, and the direction of the second tension (i.e., the tension parallel to the y direction in the figure) is toward the outside of the protective film 210.

[0086] For example, when the display device is placed horizontally, the plane where the display panel 200 is located can be arranged parallel to the horizontal plane, and the display panel 200 can be arranged above the front side of the housing 100. The first tension can be set as a vertical upward component of the tension, and the second tension can be set as a horizontal component of the tension, and the second tension is directed toward the outside of the protective film 210.

[0087] It is easy to understand that, during the production and transportation process of the display device, the direction of the pulling force applied by the housing 100 to the first adhesive portion 310 may be vertically upward, and the pulling force may include the first pulling force.

[0088] Alternatively, the pulling force applied by the housing 100 to the first adhesive portion 310 may be parallel to the horizontal direction, and the pulling force may include the second pulling force. Alternatively, the pulling force applied by the housing 100 to the first adhesive portion 310 may be tilted, and the pulling force may include the first pulling force and the second pulling force.

[0089] When the housing 100 applies a first pulling force to the first adhesive portion 310 through the extension portion 320, the extension portion 320 can be separated from the protective film 210. The extension portion 320 is spaced apart from the edge of the protective film 210, so that the first adhesive portion 310 and the second adhesive portion 330 do not contact the edge of the protective film 210. The first adhesive portion 310 is located on the inner side of the protective film 210, thereby reducing the possibility that the first adhesive portion 310 drives the edge of the protective film 210 to separate from the display panel 200.

[0090] And / or, when the housing 100 applies a second pulling force to the first adhesive portion 310 through the extension portion 320, the extension portion 320 can be in sliding contact with the protective film 210, thereby reducing the possibility of relative sliding between the protective film 210 and the display panel 200 caused by the protective tape 300, reducing the possibility of warping of the protective film 210, reducing the possibility of bubbles being generated between the protective film 210 and the display panel 200, and thereby reducing the possibility of film printing on the display panel 200.

[0091] Reference Figure 1-Figure 3 In some possible implementations, the housing 100 may include a middle frame 100 a. The middle frame 100 a may include a middle frame body 110 , and the front side of the middle frame body 110 may be connected to the backlight side of the display panel 200 , so as to be fixedly connected to the display panel 200 through the middle frame body 110 .

[0092] Exemplarily, the middle frame 100a may include a middle frame outer edge 120. The middle frame outer edge 120 may be disposed on the outer side of the middle frame body 110, and the middle frame outer edge 120 may extend toward the front side of the middle frame body 110. The inner surface of the middle frame outer edge 120 may be spaced apart from the display panel 200 to reduce the possibility of collision between the middle frame outer edge 120 and the display panel 200, and the middle frame outer edge 120 may be bonded and fixed to the second bonding portion 330.

[0093] Reference Figure 4-Figure 6 The outer edge 120 of the middle frame can be arranged around the outer side of the display panel 200. The outer edge 120 of the middle frame can provide a certain limit protection for the display panel 200, thereby reducing the possibility of the display panel 200 being damaged by collision. The outer edge 120 of the middle frame is bonded and fixed to the second adhesive portion 330, thereby realizing the connection of the protective tape 300 through the outer edge 120 of the middle frame.

[0094] The middle frame body 110 and the middle frame outer edge 120 may be integrally formed to make the structure of the middle frame 100 a more stable and reduce the possibility of deformation of the middle frame 100 a, thereby improving the limiting protection effect of the middle frame 100 a on the display panel 200 .

[0095] In the thickness direction of the display panel 200 , one end of the middle frame outer edge 120 away from the middle frame body 110 may be protruded relative to the protective film 210 .

[0096] The second adhesive portion 330 may be bonded and fixed to the housing 100, and the second adhesive portion 330 may be located outside the protective film 210. In the direction from the protective film 210 to the outer edge 120 of the middle frame, the extension portion 320 may gradually move away from the protective film 210, and the extension portion 320 and the edge of the protective film 210 may be spaced apart.

[0097] For example, refer to Figure 3 The second adhesive portion 330 can be bonded and fixed to the top surface of the middle frame outer edge 120 , and the extension portion 320 is longer to increase the range of motion of the extension portion 320 and reduce the pulling force applied by the housing 100 to the protective film 210 through the extension portion 320 .

[0098] Or, refer to Figure 6 The second adhesive portion 330 can be bonded and fixed to the side of the middle frame outer edge 120. The length of the extension portion 320 is short, so that the connection between the protective film 210 and the middle frame 100a is more stable.

[0099] In this way, in the thickness direction of the display panel 200, the end of the middle frame outer edge 120 away from the middle frame body 110 is protruded relative to the protective film 210, and the extension portion 320 is spaced apart from the edge of the protective film 210, thereby reducing the possibility of the extension portion 320 contacting the protective film 210.

[0100] When the housing 100 applies the second pulling force to the first adhesive portion 310 through the extension portion 320, the extension portion 320 is spaced apart from the edge of the protective film 210 so that the extension portion 320 does not contact the protective film 210, thereby reducing the possibility of the extension portion 320 driving the protective film 210 and the display device to move relative to each other.

[0101] In the thickness direction of the display panel 200 , one end of the middle frame outer edge 120 away from the middle frame body 110 may be arranged flush with the protective film 210 .

[0102] The second adhesive portion 330 may be bonded and fixed to the housing 100 and may be located outside the protective film 210. In the direction from the protective film 210 to the outer edge 120 of the middle frame, the extension portion 320 may be attached to the surface of the protective film 210 away from the display panel 200.

[0103] When the housing 100 applies the second pulling force to the first adhesive portion 310 through the extension portion 320 , the extension portion 320 can slide in contact with the protective film 210 , thereby reducing the possibility of relative sliding between the protective film 210 and the display panel 200 caused by the protective tape 300 .

[0104] Exemplarily, the second end of the extension portion 320 may be located outside the middle frame outer edge 120. The first portion of the second adhesive portion 330 is bonded to the outer side of the middle frame outer edge 120, and the second portion of the second adhesive portion 330 is bonded to the surface of the middle frame body 110 away from the display panel 200, thereby increasing the contact area between the second adhesive portion 330 and the housing 100, making the connection between the second adhesive portion 330 and the housing 100 more stable.

[0105] It is easy to understand that when the protective tape 300 needs to be connected to the display panel 200 and the middle frame 100a, the first adhesive portion 310 can be first bonded and fixed to the surface of the protective film 210 facing away from the display panel 200, and then the second end of the extension portion 320 can be extended from the inner side of the protective film 210 through the edge of the protective film 210 to the outer side of the protective film 210, and then the second adhesive portion 330 can be bonded and fixed to the outer side of the outer edge 120 of the middle frame, thereby realizing the bonding process of the protective tape 300.

[0106] Reference Figure 6-Figure 12 In some possible implementations, the housing 100 may include a back panel 100 b. The back panel 100 b may include a back panel body 130, a back panel side edge 140, and a fitting portion 150.

[0107] The back panel body 130 is the main structural part of the back panel 100b, the back panel side 140 is the side part connected to the back panel body 130, and the bonding part 150 is at least used to connect or fix with the display panel 200 and other components.

[0108] The back panel side edge 140 is disposed around the outer side of the back panel body 130, so as to provide additional support and structural strength for the back panel 100b. In the thickness direction of the display panel 200, the first end of the back panel side edge 140 can be connected to the back panel body 130, and the second end of the back panel side edge 140 can extend toward the front side of the back panel body 130.

[0109] The back panel side edge 140 is tightly connected to the back panel body 130 and provides better structural stability. The outer side surface of the back panel side edge 140 can be bonded and fixed to the second bonding portion 330 to achieve bonding of the protective tape 300 .

[0110] The bonding portion 150 may be connected to the second end of the back panel side 140, and the bonding portion 150 may be arranged on the inner side of the back panel side 140. The bonding portion 150 and the back panel body 130 may be spaced apart, and the surface of the bonding portion 150 facing away from the back panel body 130 is connected to the display panel 200, so that the backlight side of the display panel 200 can be bonded to the surface of the bonding portion 150 facing away from the back panel body 130.

[0111] Exemplarily, the back panel side edge 140 may be located outside the display panel 200 .

[0112] The surface of the fitting portion 150 facing away from the back panel body 130 is provided with a protrusion 151, and the protrusion 151 is located outside the display panel 200. The first adhesive portion 310 is bonded and fixed to the protective film 210, the first part of the extension portion 320 is in smooth contact with the surface of the protective film 210 facing away from the display panel 200, and the second part of the extension portion 320 is in smooth contact with the protrusion 151.

[0113] The first part of the extension portion 320 is in smooth contact with the surface of the protective film 210 facing away from the display panel 200, and the second part of the extension portion 320 is in smooth contact with the protrusion 151, so that the protrusion 151 can provide a certain support for the extension portion 320, thereby reducing the possibility of the extension portion 320 directly contacting the edge of the protective film 210. The extension portion 320 will not drive the edge of the protective film 210 to move, thereby reducing the possibility of the protective film 210 warping and the possibility of bubbles forming between the protective film 210 and the display panel 200.

[0114] The back panel side edge 140 can be arranged flush with the edge of the display panel 200. The first adhesive portion 310 is bonded and fixed to the protective film 210, the first portion of the extension portion 320 is in smooth contact with the surface of the protective film 210 away from the display panel 200, the second portion of the extension portion 320 extends toward the backlight side of the display panel 200, and the second adhesive portion 330 is bonded and fixed to the back panel side edge 140.

[0115] When the housing 100 applies a second pulling force to the first adhesive portion 310 through the extension portion 320, the extension portion 320 can slide in contact with the protective film 210, and the extension portion 320 can slide in contact with the edge of the protective film 210, thereby reducing the possibility of relative sliding between the protective film 210 and the display panel 200 caused by the protective tape 300.

[0116] It is easy to understand that when the protective tape 300 needs to be connected to the display panel 200 and the back panel 100b, the first adhesive portion 310 can be first bonded and fixed to the surface of the protective film 210 facing away from the display panel 200, and then the second end of the extension portion 320 can be extended from the inner side of the protective film 210 through the edge of the protective film 210 to the outer side of the protective film 210, and then the second adhesive portion 330 can be bonded and fixed to the outer side of the back panel side 140, thereby realizing the bonding process of the protective tape 300.

[0117] Exemplarily, the protective film 210 may be a polarizing protective film 210. The polarizing protective film 210 may be disposed on the light-emitting side of the display panel 200, so that the polarizing protective film 210 may play a certain polarizing protection role.

[0118] Reference Fig. 9 The second adhesive portion 330 can be bonded and fixed to the back plate body 130 , and the length of the extension portion 320 is longer to increase the range of movement of the extension portion 320 and reduce the pulling force applied by the housing 100 to the protective film 210 through the extension portion 320 .

[0119] Or, refer to Fig.12 The second adhesive portion 330 can be bonded and fixed to the back plate side 140. The length of the extension portion 320 is short, so that the connection between the protection film 210 and the middle frame 100a is more stable.

[0120] In some possible implementations, the first adhesive portion 310 , the second adhesive portion 330 , and the extending portion 320 may be integrally provided.

[0121] For example, glue can be applied on the surface of the substrate to form two adhesive layers spaced apart from each other. The portion of the substrate coated with the adhesive layer can form the first adhesive portion 310 and the second adhesive portion 330, and the portion of the substrate not coated with the adhesive layer can form the extension portion 320, thereby making the formation process of the first adhesive portion 310 and the second adhesive portion 330 more convenient.

[0122] The extension portion 320 may have a smooth surface facing the protection film 210. The extension portion 320 may be in smooth contact with the surface of the protection film 210 facing away from the display panel 200 through the smooth surface.

[0123] In this arrangement, the housing 100 applies a second pulling force to the first adhesive portion 310 through the extension portion 320, and the direction of the second pulling force is toward the outside of the protective film 210. The extension portion 320 is in smooth contact with the surface of the protective film 210 facing away from the display panel 200 through a smooth surface, thereby reducing the friction between the extension portion 320 and the protective film 210 and reducing the possibility of relative movement between the protective film 210 and the display panel 200.

[0124] It should be noted that the smooth surface can be configured as follows: when the extension portion 320 is in smooth contact with the surface of the protective film 210 facing away from the display panel 200 through the smooth surface, the friction force between the smooth surface and the protective film 210 is less than the bonding force between the protective film 210 and the display panel 200, so as to ensure that the protective film 210 will not detach from the display panel 200.

[0125] The number of the protective tapes 300 can be set to be multiple. Multiple protective tapes 300 can be arranged around the edge of the display panel 200. For example, multiple protective tapes 300 can be arranged at different positions of the display panel 200, and the multiple protective tapes 300 can connect and fix the display panel 200 and the housing 100 in multiple directions, so that the stability of the connection between the display panel 200 and the housing 100 can be improved by the multiple protective tapes 300.

[0126] For example, the display device may have a top side and a bottom side disposed opposite to each other, and a left side and a right side disposed opposite to each other. The protective tape 300 may be located at least one of the top side of the display device, the bottom side of the display device, the left side of the display device, and the right side of the display device.

[0127] When the display device is placed in a vertical direction, the sky side of the display device is set as the side of the display device facing upward, the ground side of the display device is set as the side of the display device facing downward, the left side of the display device is set as the side of the display device facing left, and the right side of the display device is set as the side of the display device facing right.

[0128] Reference Figure 2 and Figure 7 In some possible implementations, the protective tape 300 may be sleeved on the outer sides of the display panel 200 and the housing 100 .

[0129] In the protective tape 300 , the first adhesive portion 310 may be provided as an annular first adhesive portion 310 , the extending portion 320 may be provided as an annular extending portion 320 , and the second adhesive portion 330 may be provided as an annular second adhesive portion 330 .

[0130] The annular first adhesive portion 310 may be disposed inside the annular extension portion 320 and connected to the protective film 210 . The annular second adhesive portion 330 may be disposed outside the annular extension portion 320 and connected to the housing 100 .

[0131] It is easy to understand that the protective tape 300 is sleeved on the outside of the display panel 200 and the housing 100. When the display device shakes due to external forces or other factors, the annular first adhesive portion 310 is connected to the protective film 210 of the display panel 200, and the annular second adhesive portion 330 is connected to the housing 100. Thus, the display panel 200 and the housing 100 can be connected and fixed in multiple directions by the matching annular first adhesive portion 310 and the annular second adhesive portion 330, so that the connection between the display panel 200 and the housing 100 is more stable, reducing the possibility of relative movement between the display panel 200 and the housing 100.

[0132] For example, the distance between the first adhesive portion 310 and the edge of the protective film 210 may be greater than or equal to 5 mm and less than or equal to 15 mm.

[0133] For example, the distance between the first adhesive portion 310 and the edge of the protective film 210 can be set within any distance range of 5 mm-8 mm, 8 mm-10 mm, 10 mm-12 mm, and 12 mm-15 mm, thereby reducing the possibility of the first adhesive portion 310 causing the edge of the protective film 210 to warp up while ensuring that the display panel 200 does not produce a large displacement.

[0134] When the housing 100 applies a first pulling force to the first adhesive portion 310 through the extension portion 320, the distance between the first adhesive portion 310 and the edge of the protective film 210 is greater than or equal to 5 mm, and the position where the first adhesive portion 310 applies the pulling force to the protective film 210 is closer to the middle of the protective film 210, thereby reducing the possibility of the first adhesive portion 310 causing the edge of the protective film 210 to warp up.

[0135] During the production and transportation of the display device, when the display device shakes due to external forces or other factors, the distance between the first adhesive portion 310 and the edge of the protective film 210 is less than or equal to 15 mm, thereby reducing the distance between the first adhesive portion 310 and the casing 100 and shortening the length of the extension portion 320, thereby ensuring that the display panel 200 does not produce a large displacement.

[0136] In the extension direction of the protective tape 300, the length of the first adhesive portion 310 may be greater than or equal to 20 mm. For example, the length of the first adhesive portion 310 may be set within the length range of 20 mm-25 mm, 25 mm-30 mm, 30 mm-35 mm, and 35 mm-40 mm to ensure the bonding area between the first adhesive portion 310 and the protective film 210 and improve the stability of the bonding and fixing between the first adhesive portion 310 and the protective film 210.

[0137] The length of the second adhesive portion 330 may be greater than or equal to 20 mm. For example, the length of the second adhesive portion 330 may be set within the range of 20 mm-25 mm, 25 mm-30 mm, 30 mm-35 mm, and 35 mm-40 mm to ensure the bonding area between the second adhesive portion 330 and the housing 100 and improve the stability of the bonding and fixing between the second adhesive portion 330 and the housing 100.

[0138] It should be noted that the length of the first adhesive portion 310 is greater than or equal to 20 mm, which can ensure the bonding area between the first adhesive portion 310 and the protective film 210. When the casing 100 applies a first pulling force to the first adhesive portion 310 through the extension portion 320, the larger the bonding area between the first adhesive portion 310 and the protective film 210, the smaller the possibility of the first adhesive portion 310 detaching from the protective film.

[0139] When the housing 100 applies a second tensile force to the first adhesive portion 310 through the extension portion 320, the tensile direction of the second tensile force is located in the same plane as the length direction of the first adhesive portion 310, and the tensile direction of the second tensile force is usually set perpendicular to the length direction of the first adhesive portion 310. By setting the length of the first adhesive portion 310 to be greater than or equal to 20 mm, the first adhesive portion 310 can be used to withstand a larger second tensile force, thereby reducing the possibility of relative sliding of the first adhesive portion 310 relative to the protective film 210.

[0140] The length of the second adhesive portion 330 may be greater than or equal to 20 mm. For example, the length of the second adhesive portion 330 may be set within the range of 20 mm-25 mm, 25 mm-30 mm, 30 mm-35 mm, and 35 mm-40 mm to ensure the bonding area between the second adhesive portion 330 and the housing 100 and improve the stability of the bonding and fixing between the second adhesive portion 330 and the housing 100.

[0141] When the length of the second adhesive portion 330 is less than 15 mm, the adhesive area between the second adhesive portion 330 and the housing 100 is small, the connection stability between the second adhesive portion 330 and the housing 100 is relatively poor, and the second adhesive portion 330 is easy to detach from the housing 100, thereby affecting the adhesive stability of the second adhesive portion 330.

[0142] And / or, the length of the extension portion 320 may be greater than or equal to 15 mm in the extension direction of the protective tape 300. For example, the length of the second adhesive portion 330 may be set within the length range of 15 mm-20 mm, 20 mm-25 mm, 25 mm-30 mm, 30 mm-35 mm, and 35 mm-40 mm.

[0143] When relative movement occurs between the housing 100 and the display panel 200 , the extension portion 320 can produce a certain deformation, so that a certain buffering effect can be played by the extension portion 320 . The length of the extension portion 320 is greater than or equal to 15 mm, thereby reducing the pulling force of the housing 100 on the display panel 200 .

[0144] When the length of the extension portion 320 is less than 15 mm, relative movement occurs between the housing 100 and the display panel 200, and the deformation that can be generated by the extension portion 320 is smaller. The housing 100 is more likely to transmit tension to the display panel 200 through the extension portion 320, thereby affecting the stability of the connection between the display panel 320 and the housing 100.

[0145] When the length of the extension portion 320 is greater than 40 mm, relative movement occurs between the housing 100 and the display panel 200, the deformation that the extension portion 320 can produce is large, and the constraint produced by the extension portion 320 on the housing 100 and the display panel 200 is small, so that the connection effect between the housing 100 and the display panel 200 by the protective tape 300 is poor, and the constraint effect of the protective tape 300 is poor.

[0146] It should be noted that when the display device is installed on a mounting base such as a wall, the position of the display device usually does not change frequently, and the protective tape 300 can be removed from between the protective film 210 and the housing 100. When the display device needs to be transported, the protective tape 300 can be adhered between the protective film 210 and the housing 100.

[0147] In summary, the display device of the embodiment of the present application is provided with a protective tape 300 connecting the protective film 210 and the housing 100, and the protective tape 300 includes a first adhesive portion 310, a second adhesive portion 330 and an extension portion 320 that are connected to each other; the first adhesive portion 310 is bonded and fixed to the protective film 210, the second adhesive portion 330 is bonded and fixed to the housing 100, and the extension portion 320 extends from the inner side of the protective film 210 through the edge of the protective film 210 to the outer side of the protective film 210, and at least a portion of the extension portion 320 can be oriented toward the edge of the protective film 210.

[0148] When the display device shakes due to external forces or other factors, the display panel 200 and the housing 100 may move relative to each other, and the housing 100 may apply a pulling force to the first adhesive portion 310 through the extension portion 320. The housing 100 applies a first pulling force to the first adhesive portion 310 through the extension portion 320, and the first pulling force may deviate from the display panel 200 along the thickness direction of the display panel 200. The extension portion 320 may be separated from the protective film 210, and the extension portion 320 is spaced from the edge of the protective film 210, so that the first adhesive portion 310 and the second adhesive portion 330 do not contact the edge of the protective film 210, thereby reducing the possibility that the first adhesive portion 310 drives the edge of the protective film 210 to separate from the display panel 200.

[0149] And / or, the housing 100 applies a second pulling force to the first adhesive portion 310 through the extension portion 320, and the direction of the second pulling force is toward the outside of the protective film 210. The extension portion 320 is in sliding contact with the protective film 210, thereby reducing the relative sliding between the protective film 210 and the display panel 200 caused by the protective tape 300, reducing the possibility of the protective film 210 warping, reducing the possibility of bubbles between the protective film 210 and the display panel 200, and thereby reducing the possibility of film printing on the display panel 200.

[0150] An embodiment of the present application provides a display device, including a housing 100 , a display panel 200 , and a protective tape 300 .

[0151] The backlight side of the display panel 200 is connected to the housing 100 , and the light-emitting side of the display panel 200 is away from the housing 100 . A protective film 210 is provided on the light-emitting side of the display panel 200 , and the protective film 210 is connected to the housing 100 via a protective tape 300 .

[0152] The protective tape 300 includes a first adhesive portion 310 , a second adhesive portion 330 , and an extending portion 320 which are sequentially connected.

[0153] The first adhesive portion 310 is bonded to the surface of the protective film 210 facing away from the display panel 200 , and the second adhesive portion 330 is bonded to the housing 100 . The first adhesive portion 310 and the second adhesive portion 330 do not contact the edge of the protective film 210 .

[0154] The housing 100 can apply a first pulling force to the first adhesive portion 310 through the extension portion 320 ; the first pulling force deviates from the display panel 200 along the thickness direction of the display panel 200 , the extension portion 320 separates from the protective film 210 , and the extension portion 320 is spaced apart from the edge of the protective film 210 .

[0155] And / or, the housing 100 may apply a second pulling force to the first adhesive portion 310 through the extension portion 320 , the second pulling force is directed toward the outside of the protective film 210 , and the extension portion 320 is in sliding contact with the protective film 210 .
