The display module comprises a display panel, a cover plate, a conductive function film layer, a first conductive part and a second conductive part. The cover plate comprises a cover plate body covering the display panel and protruding parts connected with the cover plate body and distributed around the cover plate body. The first conductive parts are located on the sides, facing the display panel, of the protruding parts and distributed around the cover plate body. When the negative charges distributed on the surface of the cover plate move and diffuse to the edge of the cover plate along the surface of the cover plate, the negative charges diffuse and converge in the first conductive part. As the first conductive part is electrically connected with the conductive function layer through the second conductive part, the negative charges are conducted to the conductive function layer through the second conductive part to be released. And the second conductive part is insulated from the outer side surface of the display panel, so that negative charges in the second conductive part cannot enter the display panel from the outer side surface of the display panel, and the phenomenon that the whole screen of the display panel turns green is avoided.

Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and display device. Background Technology

[0002] With the development of display technology, the demand for and application range of display devices are constantly expanding. Commonly used display devices include mobile phones, televisions, tablets, laptops, and monitors.

[0003] Display devices typically include a display module. The display module may include a display panel and a protective cover plate bonded to the front side of the display panel (i.e., the display surface). The protective cover plate can be bonded to the display panel using optical adhesive. In this way, the protective cover plate can protect the display panel from the front side.

[0004] During the bonding process between the protective cover and the display panel, optical adhesive may overflow, causing the outer side of the display panel to come into contact with the optical adhesive. Furthermore, the surface of the protective cover is prone to static electricity, with negative charges distributed on its surface. These charges can be conducted and diffused to the display panel through the optical adhesive, causing a green screen phenomenon at the edges of the display panel. As the charge accumulates further, the entire screen may turn green. Utility Model Content

Negative charges generated by static electricity are distributed on the surface of the cover plate on the side facing away from the display panel.

When the negative charges diffuse along the surface of the cover plate to the edge of the cover plate, they can diffuse through the outer side of the cover plate and accumulate in the first conductive portion distributed around the cover plate body. Furthermore, since the first conductive portion is electrically connected to the conductive functional layer through the second conductive portion, the negative charges that accumulate from the outer side of the cover plate to the first conductive portion can be conducted and diffused to the conductive functional layer through the second conductive portion. In this way, the negative charges can be released through the first conductive portion, the second conductive portion, and the conductive functional layer, preventing negative charges from entering the display panel from the outer side of the display panel, thus avoiding the phenomenon of the entire screen turning green. In addition, since the second conductive portion is insulated from the outer side of the display panel, during the release of negative charges, the negative charges in the second conductive portion will not enter the display panel from the outer side of the display panel. Therefore, the display panel will not exhibit the phenomenon of the entire screen turning green, resulting in a better display effect. Attached Figure Description

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0066] Please refer to Figure 1 and Figure 2 , Figure 1 This is a top view of a display module provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the film structure of the display module at point A-A'. The display module 000 includes: a display panel 100, a cover plate 200, a conductive functional film layer 300, a first conductive part 400, and a second conductive part 500.

[0067] The cover plate 200 in the display module 000 is located on the display side of the display panel 100. The cover plate 200 in the display module 000 may include: a cover plate body 210 covering the display panel 100, and a protrusion 220 connected to the cover plate body 210.

[0068] In this application, the portion of the cover plate 200 that overlaps with the display panel 100 can be referred to as the cover plate body 210, and the portion of the cover plate 200 that protrudes from the display panel 100 in a direction parallel to the cover plate 200 can be referred to as the protrusion 220. Therefore, the protrusion 220 in the cover plate 200 can be annular, and the protrusion 220 can be distributed around the cover plate body 210. Here, the display side of the display panel 100 refers to the side of the display panel 100 used for displaying images. The display side of the display panel 100 can be fitted with the cover plate body 210 in the cover plate 200, so that the cover plate body 210 can protect the display side of the display panel 100.

[0069] The conductive functional film layer 300 in the display module 000 is located on the side of the display panel 100 away from the cover plate 200, and the conductive functional film layer 300 is insulated from the display panel 100. Here, the conductive functional film layer 300 can be used to protect the side of the display panel 100 away from the display side, and the conductive functional film layer 300 is conductive, serving as a grounding component in the display module 000. That is, the conductive functional film layer 300 can be connected to the ground wire. For example, the conductive functional film layer 300 can be made of copper foil.

[0070] The first conductive part 400 in the display module 000 is located on the side of the protrusion 220 facing the display panel 100, and the first conductive part 400 is distributed around the cover plate body 210.

[0071] A portion of the second conductive part 500 in the display module 000 is connected to the first conductive part 400, and another portion can be bent to connect to the conductive functional layer 300 on the side away from the display panel 100, so as to realize the electrical connection between the first conductive part 400 and the conductive functional layer 300.

[0072] like Figure 2As shown, negative charges generated by static electricity are distributed on the surface of the cover plate 200 on the side opposite to the display panel 100. These negative charges can move and diffuse along the surface of the cover plate 200 due to mutual repulsion. When the negative charges diffuse along the surface of the cover plate 200 to the edge of the cover plate 200, the negative charges can diffuse through the outer side of the cover plate 200 and converge in the first conductive portion 400 distributed around the cover plate body 210. Since the first conductive portion 400 is electrically connected to the conductive functional layer 300 through the second conductive portion 500, the negative charges that converge from the outer side of the cover plate 200 to the first conductive portion 400 can all be conducted and diffused to the conductive functional layer 300 through the second conductive portion 500.

[0073] In this way, negative charges can be released through the first conductive part 400, the second conductive part 500, and the conductive functional layer 300, preventing negative charges from entering the display panel 100 from its outer surface. This would make the light-emitting devices in the display panel 100 that emit green light brighter, resulting in a green screen phenomenon. Furthermore, since the second conductive part 500 is insulated from the outer surface of the display panel 100, during the release of negative charges, the negative charges in the second conductive part 500 will not enter the display panel 100 from its outer surface, preventing the display panel 100 from exhibiting a green screen phenomenon and resulting in a better display effect.

[0074] In summary, the display panel provided in this application includes: a display panel, a cover plate, a conductive functional film layer, a first conductive portion, and a second conductive portion. The cover plate includes: a cover plate body covering the display panel, and protrusions connected to and distributed around the cover plate body. The first conductive portion is located on the side of the protrusion facing the display panel and is distributed around the cover plate body. Negative charges generated by static electricity are distributed on the surface of the cover plate away from the display panel. These negative charges can move and diffuse along the surface of the cover plate due to mutual repulsion. When the negative charges diffuse along the surface of the cover plate to the edge of the cover plate, they can diffuse through the outer side of the cover plate and accumulate in the first conductive portion distributed around the cover plate body. Since the first conductive portion is electrically connected to the conductive functional layer through the second conductive portion, the negative charges that accumulate from the outer side of the cover plate to the first conductive portion can be conducted and diffused to the conductive functional layer through the second conductive portion. In this way, the negative charges can be released through the first conductive portion, the second conductive portion, and the conductive functional layer, preventing negative charges from entering the display panel from the outer side of the display panel and thus avoiding the phenomenon of the entire screen turning green. Furthermore, because the second conductive part is insulated from the outer surface of the display panel, during the release of negative charge, the negative charge in the second conductive part will not enter the display panel from the outer surface. Therefore, the display panel will not exhibit an overall green tint, resulting in a better display effect.

[0075] In the embodiments of this application, please refer to Figure 3 , Figure 3 This is a schematic diagram of the film layer structure of a display module provided in an embodiment of this application. The display module 000 may further include a masking ink layer 600, which is manufactured using a screen printing process. The masking ink layer 600 in the display module 000 is located on the side of the first conductive part 400 facing the protrusion 220, the masking ink layer 600 is distributed around the cover plate body 210, and the masking ink layer 600 covers the side of the protrusion 220 facing the display panel 100. Here, the masking ink layer 600 can be used to form the frame of the display module 000, masking the first conductive part 400, the second conductive part 500, and the driving circuit and connecting traces in the display module 000, thereby achieving an aesthetic purpose.

[0076] It should be noted that the first conductive portion 400 in the display module 000 can also be a conductive ink layer manufactured using a screen printing process. Furthermore, the orthographic projection of the first conductive portion 400 on the cover plate 200 overlaps with the orthographic projection of the masking ink layer 600 on the cover plate 200. In this way, the first conductive portion 400 distributed around the outer side of the display panel 100 does not need to occupy additional space, which is beneficial for achieving a narrow bezel in the display module 000.

[0077] The display module 000 also includes: a first functional film layer 700 located between the cover plate 200 and the display panel 100, and a second functional film layer 800 located between the display panel 100 and the conductive functional layer 300.

[0078] The first functional film layer 700 in the display module 000 may include a polarizer 710 and an optical adhesive layer 720. The polarizer 710 in the first functional film layer 700 can be bonded to the display side of the display panel 100. The polarizer 710 can reduce the reflectivity of the display panel 100 to ambient light, so as to ensure that the display area within the display panel 100 displays a better image.

[0079] The optical adhesive layer 720 in the display module 000 is located between the polarizer 710 and the cover plate 200. This optical adhesive layer 720 is used to bond the cover plate 200 to the polarizer 710, and is typically made of a transparent adhesive (e.g., acrylic adhesive). This ensures that light emitted from the display panel 100 passes through the optical adhesive layer 720 and the cover plate 200 before exiting. Furthermore, the optical adhesive layer 720 also has good cushioning properties, thus reducing the probability of the cover plate 200 breaking after the front of the display module 000 is subjected to impact.

[0080] The second functional film layer 800 in the display module 000 may include a first support layer 810 and a polyimide film layer 820. The first support layer 810 in the second functional film layer 800 can be bonded to the side of the display panel 100 opposite to the display side, and the first support layer 810 can be used to support the display panel 100. The polyimide film layer 820 in the second functional film layer 800 is located between the first support layer 810 and the conductive functional layer 300, so that the first support layer 810 and the conductive functional layer 300 are electrically insulated.

[0081] In the embodiments of this application, such as Figure 3 As shown, the second conductive portion 500 in the display module 000 includes: a first planar conductive segment 510 and a second planar conductive segment 520, and a bent conductive segment 530 for connecting the first planar conductive segment 510 and the second planar conductive segment 520.

[0082] In this configuration, the first planar conductive segment 510 is connected to the side of the first conductive portion 400 opposite to the protrusion 220, and the second planar conductive segment 520 is connected to the side of the conductive functional layer 300 opposite to the display panel 100. For example, after the second conductive portion 500 is connected to the side of the first conductive portion 400 opposite to the protrusion 220 via the first planar conductive segment 510, the second conductive portion 500 can be bent by the bending conductive segment 530, allowing the second planar conductive segment 520 in the second conductive portion 500 to connect to the side of the conductive functional layer 300 opposite to the display panel 100.

[0083] In this case, in order to effectively prevent negative charges flowing through the bent conductive section 530 from entering the display panel 100, the bent conductive section 530 is insulated from the outer surface of the display panel 100.

[0084] In one possible implementation, the display module 000 may further include a first insulating portion 900. At least a portion of the first insulating portion 900 is located between the bent conductive section 530 and the outer surface of the display panel 100. Thus, the first insulating portion 900 effectively prevents negative charges flowing through the bent conductive section 530 from entering the display panel 100, preventing the display panel 100 from exhibiting a full-screen green tint and resulting in better display performance.

[0085] It should be noted that during the bonding process of the cover plate 200 and the polarizer 710, the optical adhesive layer 720 in the first functional film layer 700 will overflow and come into contact with the outer surface of the display panel 100. If the bent conductive section 530 comes into contact with the optical adhesive layer 720 during the bending process of the second conductive part 500, the negative charge flowing through the bent conductive section 530 can enter the display panel 100 through the optical adhesive layer 720, causing the light-emitting device in the display panel 100 to be brighter, resulting in the phenomenon of the entire screen turning green.

[0086] Furthermore, if the second conductive part 500 comes into contact with the first support layer 810 in the second functional film layer 800 during the bending process, the negative charge flowing through the second conductive part 500 can enter the display panel 100 through the first support layer 810, causing the light-emitting device in the display panel 100 to emit green light to become brighter, resulting in the phenomenon of the entire screen turning green.

[0087] Therefore, in order to effectively prevent the negative charge flowing through the second conductive part 500 from entering the display panel 100 through the first functional film layer 700 and the second functional film layer 800, both the first functional film layer 700 and the second functional film layer 800 are insulated from the second conductive part 500.

[0088] For example, such as Figure 3 As shown, to prevent the bent conductive segment 530 in the second conductive portion 500 from contacting the first functional film layer 700, the first insulating portion 900 extends between the bent conductive segment 530 and the outer surface of the first functional film layer 700; and to prevent the bent conductive segment 530 in the second conductive portion 500 from contacting the second functional film layer 800, the first insulating portion 900 can also extend between the outer surface of the bent conductive segment 530 and the second functional film layer 800. In this way, the negative charge flowing through the bent conductive segment 530 will not enter the display panel 100 through the first functional layer 700 and the second functional layer 800, preventing the display panel 100 from exhibiting a full-screen green tint and resulting in a better display effect.

[0089] In this application, the first insulating portion 900 may also extend between the first planar conductive segment 510 and the protrusion 220, and / or the first insulating portion 900 may also extend between the second planar conductive segment 520 and the conductive functional layer 300.

[0090] For example, such as Figure 3 As shown, the first insulating portion 900 extends between the first planar conductive section 510 and the protrusion 220, and between the second planar conductive section 520 and the conductive functional layer 300. Thus, the side of the second conductive portion 500 facing the display panel 100 only contacts the first conductive portion 400 and the conductive functional layer 300, further preventing negative charges flowing through the second conductive portion 500 from entering the display panel 100. This prevents the display panel 100 from exhibiting a full-screen green tint, resulting in a better display effect.

[0091] In this embodiment, the first insulating portion 900 can be an adhesive insulating layer. For example, the first insulating portion 900 can be insulating tape attached to the second conductive portion 500. Thus, the bent conductive segment 530 in the second conductive portion 500 can be bonded to the outer surface of the display panel 100 via the first insulating portion 900. In one possible implementation, the bent conductive segment 530 can be bonded to the outer surfaces of the first functional film layer 700, the display panel 100, and the second functional film layer 800 via the first insulating portion 900. Furthermore, the adhesive first insulating portion 900 effectively reduces the possibility of detachment between the second conductive portion 500 and the first insulating portion 900, thereby reducing the possibility of negative charges flowing through the second conductive portion 500 entering the display panel 100.

[0092] Here, the second conductive part 500 can be made of a flexible conductive material. For example, the second conductive part 500 can be a flexible conductive cloth. In this way, it can be ensured that the bent conductive section 530 in the second conductive part 500 can be bent more easily, and can be tightly attached to the outer surface of the first functional film layer 700, the display panel 100 and the second functional film layer 800 by insulating tape (i.e., the first insulating part 900).

[0093] In this embodiment, since the protrusion 220 in the cover plate 200 is annular, the first conductive portion 400 provided on one side of the protrusion 220 can also be annular, and the first conductive portion 400 can also be distributed around the cover plate body 210 in the cover plate 200. The second conductive portion 500 in the display module 000 can be strip-shaped. The extending direction of the second conductive portion 500 can intersect the extending direction of the portion of the first conductive portion 400 connected to the second conductive portion 500. For example, as... Figure 1 As shown, when the extending direction of the portion where the first conductive part 400 and the second conductive part 500 are connected is parallel to the extending direction of the lower border of the display module 000, the extending direction of the second conductive part 500 can be perpendicular to the extending direction of the lower border of the display module 000.

[0094] In this configuration, the first insulating portion 900 in the display module 000 can also be strip-shaped; the extending direction of the first insulating portion 900 is parallel to the extending direction of the second conductive portion 500. In the extending direction perpendicular to the second conductive portion 500, the width of the strip-shaped first insulating portion 900 can be greater than or equal to the width of the strip-shaped second conductive portion 500. This effectively prevents the second conductive portion 500 from contacting the outer surface of the display panel 100 due to the narrowness of the strip-shaped first insulating portion 900, thus preventing negative charges flowing through the second conductive portion 500 from entering the display panel 100.

[0095] Furthermore, the strip-shaped second conductive portion 500 facilitates bending, allowing for better conductivity between the first conductive portion 400 and the conductive functional layer 300. Additionally, the annular first conductive portion 400 concentrates negative charges generated at various locations on the cover plate 200, guiding them to the first conductive portion 300, and then through the strip-shaped second conductive portion 500 to the conductive functional layer 300. Thus, the combination of the annular first conductive portion 400 and the strip-shaped second conductive portion 500 effectively directs negative charges generated on the surface of the cover plate 200 to the conductive functional layer 300.

[0096] In the embodiments of this application, please refer to Figure 4 and Figure 5 , Figure 4 This is a top view of another display module provided in an embodiment of this application. Figure 5 yes Figure 4 The diagram shows the film layer structure of the display module at point B-B'. The display module 000 contains multiple second conductive portions 500, which are spaced apart and arranged around the periphery of the display panel 100. This allows negative charges conducted from the cover plate 200 to the first conductive portion 400 to be rapidly conducted to the conductive functional layer 300 via the multiple second conductive portions 500, improving the efficiency of negative charge release.

[0097] In this application, as Figure 5 As shown, the display panel 100 in the display module 000 includes: a first panel portion 110 and a second panel portion 120 disposed opposite to each other, and a panel bending portion 130 for connecting the first panel portion 110 and the second panel portion 120. That is, the panel bending portion 130 can be located between the first panel portion 110 and the second panel portion 120, and one side of the panel bending portion 130 can be connected to the first panel portion 110, and the other side of the panel bending portion 130 can be connected to the second panel portion 120. The first panel portion 110 has a display surface S, and the display module 000 can display an image through the display surface S of the first panel portion 110. A cover plate 200 in the display module 000 covers the first panel portion 110, and a conductive functional layer 300 is located on the side of the first panel portion 110 opposite to the cover plate 200.

[0098] It should be noted that after the panel bending portion 130 in the display module 000 is bent, the second panel portion 120 also needs to be attached to the conductive functional layer 300. For example, as shown... Figure 5As shown, the display module 000 further includes a second support layer 1500 and a support pillar 1600 located between the second panel portion 120 and the conductive functional layer 300. The second support layer 1500 can be used to support the second panel portion 120; the support pillar 1600 can be used to bond the conductive functional layer 300 and the second support layer 1500, and to support both the conductive functional layer 300 and the second support layer 1500.

[0099] Typically, the second panel portion 120 is wider, and electronic components (e.g., driver chips) are distributed on the panel bend portion 130. Therefore, multiple second conductive portions 500 need to be distributed on the outer surface of the first panel portion 100 where the panel bend portion 130 is not located, to ensure that the second conductive portions 500 do not cross the panel bend portion 130 before connecting to the conductive functional layer 300. This not only reduces the length of the second conductive portions 500 but also ensures that the second conductive portions 500 do not interfere with the electronic components disposed on the panel bend portion 130.

[0100] For example, such as Figure 4 As shown, the display module 000 is typically rectangular. The panel bending portion 130 in the display module 000 can be located on the lower side of the display module 000. There are no panel bending portions 130 on the left, top, or right sides of the display module 000. Therefore, two second conductive portions 500 are respectively disposed on the lower side of the display module 000, and these two second conductive portions 500 can be located on both sides of the panel bending portion 130. This provides sufficient space for the second conductive portions 500, and the left, top, and right bezels of the display module 000 are also relatively narrow, which is beneficial for achieving a narrow bezel design for the display module 000.

[0101] In this embodiment, the optical adhesive layer 720 in the first functional film layer 700 may overflow. The overflowed portion of the optical adhesive layer 720 may simultaneously contact the outer surface of the display panel 100 and the portion of the first conductive portion 400 not connected to the second conductive portion 500. Therefore, the negative charge in the first conductive portion 400 can enter the display panel 100 through the overflowed portion of the optical adhesive layer 720, resulting in the entire display panel 100 exhibiting a greenish tinge.

[0102] To solve this problem, please refer to... Figure 6 and Figure 7 , Figure 6 This is a top view of another display module provided in the embodiments of this application. Figure 7 yes Figure 6The diagram shows a schematic of the film layer structure of the display module at C-C'. The display module 000 also includes a second insulating portion 1000. The second insulating portion 1000 is located on the side of the first conductive portion 400 opposite to the protrusion 220, the second insulating portion 1000 is distributed around the cover plate body 210, and the second insulating portion 1000 covers at least a portion of the first conductive portion 400. For example, the second insulating portion 1000 in the display module 000 can be an insulating ink layer made using a screen printing process.

[0103] In this way, even if the optical adhesive layer 720 overflows, the first conductive part 400 can be covered by the second insulating part 1000, which can also achieve insulation between the first conductive part 400 and the overflowing part of the optical adhesive layer 720. This reduces the probability that the negative charge in the first conductive part 400 will enter the display panel 100 through the overflowing part of the optical adhesive layer 720. The possibility of the display panel 100 showing a green screen is low, resulting in a better display effect of the display panel 100.

[0104] In one possible scenario, the portion of the first conductive portion 400 that connects to the second conductive portion 500 is the connecting conductive portion 410, and the other portions of the first conductive portion 400, excluding the connecting conductive portion 410, are the portions surrounding the conductive portion 420.

[0105] In this configuration, the second insulating portion 1000 has a cutout area W. The orthographic projection of the connecting conductive portion 410 on the cover plate 200 lies within the orthographic projection of the cutout area W on the cover plate 200, and the orthographic projection of the surrounding conductive portion 420 on the cover plate 200 lies within the orthographic projection of the second insulating portion 1000 on the cover plate 200. That is, the second insulating portion 1000 covers the surrounding conductive portion 420 in the first conductive portion 400. Thus, the surrounding conductive portion 420 is insulated from the outer surface of the display panel 100, and the negative charge in the surrounding conductive portion 420 can only be conducted to the second conductive portion 500 through the connecting conductive portion 410. In other words, the negative charge in the first conductive portion 400 is only conducted to the conductive functional layer 300 through the second conductive portion 500, preventing the negative charge in the first conductive portion 400 from entering the display panel 100 and causing the entire display panel 100 to appear green, resulting in a better display effect for the display panel 100.

[0106] It should be noted that the above embodiment is illustrated using a flat display screen as an example. In other possible implementations, the display module can also be a curved display screen. In this case, it is only necessary to set the edge portion of the cover plate 200 as a curved portion.

[0107] In summary, the display panel provided in this application includes: a display panel, a cover plate, a conductive functional film layer, a first conductive portion, and a second conductive portion. The cover plate includes: a cover plate body covering the display panel, and protrusions connected to and distributed around the cover plate body. The first conductive portion is located on the side of the protrusion facing the display panel and is distributed around the cover plate body. Negative charges generated by static electricity are distributed on the surface of the cover plate away from the display panel. These negative charges can move and diffuse along the surface of the cover plate due to mutual repulsion. When the negative charges diffuse along the surface of the cover plate to the edge of the cover plate, they can diffuse through the outer side of the cover plate and accumulate in the first conductive portion distributed around the cover plate body. Since the first conductive portion is electrically connected to the conductive functional layer through the second conductive portion, the negative charges that accumulate from the outer side of the cover plate to the first conductive portion can be conducted and diffused to the conductive functional layer through the second conductive portion. In this way, the negative charges can be released through the first conductive portion, the second conductive portion, and the conductive functional layer, preventing negative charges from entering the display panel from the outer side of the display panel and thus avoiding the phenomenon of the entire screen turning green. Furthermore, because the second conductive part is insulated from the outer surface of the display panel, during the release of negative charge, the negative charge in the second conductive part will not enter the display panel from the outer surface. Therefore, the display panel will not exhibit an overall green tint, resulting in a better display effect.

[0108] This application embodiment also provides a display device, which may include: a frame, and a display module connected to the frame, wherein the display module is... Figures 1 to 7 The display module 000 shown can be any product or component with a display function, such as electronic paper, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0109] It should be noted that the display device includes Figures 1 to 5 When the provided display module 000 has a conductive frame, the frame can also serve as a charge release structure for the display module 000, further improving the release efficiency of negative charges.

[0110] For example, please refer to Figure 8 , Figure 8 This is a schematic diagram of the film layer structure of a display device provided in an embodiment of this application. The display device 001 includes: a frame 1100, and a display module 000 connected to the frame 1100. The display module 000 is... Figures 1 to 5The display module 000 is shown. The frame 1100 in the display device 001 is conductive, and the frame 1100 may include: a side plate 1110, and a first support platform 1120 fixedly connected to the side plate 1110 on its inner side. The first support platform 1120 is used to support the protrusion 220 in the cover plate 200. The first conductive part 400 is electrically connected to the first support platform 1120.

[0111] In this application, negative charges generated by static electricity are distributed on the surface of the cover plate 200 on the side opposite to the display panel 100. These negative charges can move and diffuse along the surface of the cover plate 200 due to mutual repulsion. When the negative charges diffuse along the surface of the cover plate 200 to the edge of the cover plate 200, the negative charges can diffuse through the outer side of the cover plate 200 and be transferred to the first conductive part 400. Here, since the first conductive part 400 is annular, the negative charges generated at various locations on the cover plate 200 can be concentrated and guided to the first conductive part 400. Furthermore, since the first conductive part 400 is electrically connected to the first support platform 1120, the negative charges conducted to the first conductive part 400 can be conducted and diffused into the first support platform 1120, and thus the negative charges can be released through the frame 1100.

[0112] It should be noted that the display device 001 may further include a conductive adhesive portion 1200. The conductive adhesive portion 1200 is located between the first conductive portion 400 and the first support platform 1120, and the first conductive portion 400 can be connected to the first support platform 1120 via the conductive adhesive portion 1200. The conductive adhesive portion 1200 is conductive, and the first conductive portion 400 and the frame 1100 can be electrically connected via the conductive adhesive portion 1200, allowing negative charges in the first conductive portion 400 to be released through the frame 1100. Furthermore, the conductive adhesive portion 1200 is adhesive, allowing the display module 000 and the frame 1100 to be assembled together via the conductive adhesive portion 1200.

[0113] In addition, the frame 1100 may also include a second support platform 1130, which is fixedly connected to the side of the first support platform 1120 away from the side plate 1110, and the side of the first support platform 1120 facing the cover plate 200 is closer to the cover plate 200 than the side of the second support platform 1130 facing the cover plate 200.

[0114] In this configuration, the display device 001 may further include a sealing portion 1300. At least a portion of the sealing portion 1300 is located between the second support platform 1130 and the protrusion 220 in the cover plate 200, and the protrusion 220 is connected to the second support platform 1130 via the sealing portion 1300. The sealing portion 1300 is adhesive, which can bond the cover plate 200 and the frame 1100 together, making the assembled display module 000 and the frame 1100 more firmly bonded and less prone to detachment.

[0115] It should be noted that the sealing part 1300 also has insulation properties, and the sealing part 1300 in the display device 001 may include: a first sealing adhesive 1310 and a second sealing adhesive 1320 connected to each other.

[0116] In a direction perpendicular to the cover plate 200, the first sealing adhesive 1310 is located between the second support platform 1130 and the protrusion 220 in the cover plate 200. Through the first sealing adhesive 1310, the second support platform 1130 is able to support the protrusion 220 in the cover plate 200.

[0117] In a direction parallel to the cover plate 200, the second sealing colloid 1320 is located between the frame 1100 and the display panel 100. The second sealing colloid 1320 also has good cushioning properties, thus reducing the probability of damage to the display panel 100 after the side of the display device 001 is subjected to impact force. Furthermore, because the sealing part 1300 is insulating, negative charges conducted to the frame 1100 cannot enter the display panel 100 from the side, preventing the entire display panel 100 from displaying a green tint and resulting in better display performance.

[0118] In summary, this application provides a display device. The frame is conductive, and a first conductive portion is electrically connected to a first support platform within the frame. Thus, negative charges distributed on the surface of the cover plate away from the display panel can diffuse along the surface of the cover plate. Negative charges diffusing to the edge of the cover plate 200 can diffuse through the outer surface of the cover plate and be transferred to the first conductive portion. Here, because the first conductive portion is annular, negative charges generated at various locations on the cover plate can be concentrated and directed to the first conductive portion. Furthermore, since the first conductive portion is electrically connected to the first support platform, the negative charges conducted to the first conductive portion can diffuse into the first support platform, thereby releasing the negative charges through the frame.

[0119] In the embodiments of this application, please refer to Figure 9 , Figure 9 This is a schematic diagram of the film layer structure of another display device provided in an embodiment of this application. The display device 001 includes: a display panel 100, a cover plate 200, a conductive adhesive part 1200, and a frame 1100.

[0120] The cover plate 200 in the display device 001 is located on the display side of the display panel 100. The cover plate 200 includes: a cover plate body 210 covering the display panel 100, and a protrusion 220 connected to the cover plate body 210.

[0121] In this application, the portion of the cover plate 200 that overlaps with the display panel 100 can be referred to as the cover plate body 210, and the portion of the cover plate 200 that protrudes from the display panel 100 in a direction parallel to the cover plate 200 can be referred to as the protrusion 220. Therefore, the protrusion 220 in the cover plate 200 can be annular, and the protrusion 220 can be distributed around the cover plate body 210. Here, the display side of the display panel 100 refers to the side of the display panel 100 used for displaying images. The display side of the display panel 100 can be fitted with the cover plate body 210 in the cover plate 200, so that the cover plate body 210 can protect the display side of the display panel 100.

[0122] The conductive adhesive portion 1200 in the display device 001 is located on the side of the protrusion 220 facing the display panel 100, and the conductive adhesive portion 1200 can be annular and distributed around the cover plate body 210.

[0123] The frame 1100 in the display device 001 is conductive, and the frame 1100 may include: a side plate 1110, and a first support platform 1120 fixedly connected to the side plate 1100 on its inner side. The first support platform 1120 is used to support the protrusion 220 in the cover plate 200. Since the conductive adhesive part 1200 is adhesive, the display module 000 and the frame 1100 can be assembled together through the conductive adhesive part 1200. For example, Figure 9 As shown, the protrusion 220 in the cover plate 200 can be connected to the first support platform 1120 through the conductive adhesive part 1200, so that the display module 000 and the frame 1100 are assembled together through the conductive adhesive part 1200.

[0124] In this application, negative charges generated by static electricity are distributed on the surface of the cover plate 200 on the side opposite to the display panel 100. These negative charges can move and diffuse along the surface of the cover plate 200 due to mutual repulsion. When the negative charges diffuse along the surface of the cover plate 200 to the edge of the cover plate 200, the negative charges can diffuse through the outer side of the cover plate 200 and converge in the conductive adhesive portions 1200 distributed around the cover plate body 210. Here, since the conductive adhesive portions 1200 are annular, the negative charges generated at various locations on the cover plate 200 can be concentrated and guided to the conductive adhesive portions 1200. Furthermore, since the conductive adhesive portions 1200 are connected to the first support platform 1120, the negative charges that converge from the outer side of the cover plate 200 to the conductive adhesive portions 1200 can all be conducted and diffused to the first support platform 1120 through the conductive adhesive portions 1200.

[0125] In this way, the negative charge on the cover plate 200 can be released through the conductive adhesive part 1200 and the first support platform 1120, which reduces the probability of the negative charge entering the display panel 100 from the outer side of the display panel 100. The possibility of the display panel 100 showing a whole screen green is low, resulting in a better display effect of the display panel 100.

[0126] In this embodiment of the application, the frame 1100 may further include a second support platform 1130. The second support platform 1130 is fixedly connected to the side of the first support platform 1120 away from the side plate 1110, and the side of the first support platform 1120 facing the cover plate 200 is closer to the cover plate 200 than the side of the second support platform 1130 facing the cover plate 200.

[0127] In this case, the display device 001 may further include: a first sealing compound 1310 and a second sealing compound 1320 connected to each other.

[0128] In the direction perpendicular to the cover plate 200, the first sealing adhesive 1310 is located between the second support platform 1130 and the protrusion 220 in the cover plate 200. The first sealing adhesive 1310 can bond the cover plate 200 and the frame 1100 together, making the assembled display module 000 and the frame 1100 more firmly bonded and less prone to detachment. Furthermore, through the first sealing adhesive 1310, the second support platform 1130 can support the protrusion 220 in the cover plate 200.

[0129] In a direction parallel to the cover plate 200, the second sealing colloid 1320 is located between the frame 1100 and the display panel 100. The second sealing colloid 1320 also has good cushioning properties, thus reducing the probability of damage to the display panel 100 after the side of the display device 001 is subjected to impact force. Furthermore, because the sealing part 1300 is insulating, negative charges conducted to the frame 1100 cannot enter the display panel 100 from the side, preventing the entire display panel 100 from displaying a green tint and resulting in better display performance.

[0130] In summary, the display device provided in this application includes: a display panel, a cover plate, a conductive adhesive portion, and a frame. The cover plate includes: a cover plate body covering the display panel, and protrusions connected to the cover plate body, the protrusions being distributed around the cover plate body. The conductive adhesive portion is located on the side of the protrusion facing the display panel and is distributed around the cover plate body. The frame may include: a side plate, and a first support platform fixedly connected to the side plate on its inner side. Negative charges generated by static electricity are distributed on the surface of the cover plate on the side away from the display panel. These negative charges can move and diffuse along the surface of the cover plate due to mutual repulsion. As the negative charges diffuse along the surface of the cover plate to the edge of the cover plate, they can diffuse through the outer surface of the cover plate and converge in the conductive adhesive portion distributed around the cover plate body. Here, because the conductive adhesive portion is annular, the negative charges generated at various locations on the cover plate can be concentrated and guided to the conductive adhesive portion. Furthermore, since the conductive adhesive portion is connected to the first support platform, all negative charges that converge on the conductive adhesive portion from the outer side of the cover plate can be conducted and diffused to the first support platform through the conductive adhesive portion. In this way, the negative charges on the cover plate can be released through the conductive adhesive portion and the first support platform, reducing the probability of negative charges entering the display panel from the outer side of the display panel. This lowers the possibility of the display panel exhibiting a full-screen green tint, resulting in a better display effect.

[0131] This application also provides another display module, please refer to... Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the film layer structure of another display module provided in the embodiments of this application. Figure 11 This is a schematic diagram of the film layer structure of another display module provided in the embodiments of this application. The display module 000 includes: a display panel 100, a cover plate 200, a first functional film layer 700, and a fourth insulating part 1400.

[0132] The display panel 100 in the display module 000 includes: a first panel portion 110 and a second panel portion 120 disposed opposite to each other, and a panel bending portion 130 for connecting the first panel portion 110 and the second panel portion 120. That is, the panel bending portion 130 can be located between the first panel portion 110 and the second panel portion 120, and one side of the panel bending portion 130 can be connected to the first panel portion 110, and the other side of the panel bending portion 130 can be connected to the second panel portion 120. The first panel portion 110 has a display surface S, and the display module 000 can display an image through the display surface S of the first panel portion 110.

[0133] The cover plate 200 in the display module 000 is located on the side of the first panel portion 110 away from the second panel portion 120. The cover plate 200 includes: a cover plate body 210 covering the display panel 100, and a protrusion 220 connected to the cover plate body 210.

[0134] In this application, the portion of the cover plate 200 that overlaps with the display panel 100 can be referred to as the cover plate body 210, and the portion of the cover plate 200 that protrudes from the display panel 100 in a direction parallel to the cover plate 200 can be referred to as the protrusion 220. Therefore, the protrusion 220 in the cover plate 200 can be annular, and the protrusion 220 can be distributed around the cover plate body 210. Here, the first panel portion 110 can be fitted to the cover plate body 210 in the cover plate 200, so that the cover plate body 210 can protect the side of the first panel portion 110 with the display surface S. Furthermore, the protrusion 220 in the cover plate 200 can cover the panel bend portion 130; that is, in a direction parallel to the display surface S of the display panel 100 and perpendicular to the bending axis of the panel bend portion 130, the side of the protrusion 220 facing away from the cover plate body 210 protrudes from the side of the panel bend portion 130 facing away from the first panel portion 110. In this way, the protrusion 220 in the cover plate 200 can protect the side of the panel bend 130 facing the cover plate 200.

[0135] The first functional film layer 700 in the display module 000 is located between the first panel portion 110 and the cover plate 200.

[0136] It should be noted that the first functional film layer 700 in the display module 000 may include a polarizer 710 and an optical adhesive layer 720. The polarizer 710 in the first functional film layer 700 can be bonded to the display side of the display panel 100. The polarizer 710 can reduce the reflectivity of the display panel 100 to ambient light, so as to ensure that the display area within the display panel 100 displays a better image.

[0137] The optical adhesive layer 720 in the display module 000 is located between the polarizer 710 and the cover plate 200. This optical adhesive layer 720 is used to bond the cover plate 200 to the polarizer 710, and is typically made of a transparent adhesive (e.g., acrylic adhesive). This ensures that light emitted from the display panel 100 passes through the optical adhesive layer 720 and the cover plate 200 before exiting. Furthermore, the optical adhesive layer 720 also has good cushioning properties, thus reducing the probability of the cover plate 200 breaking after the front of the display module 000 is subjected to impact.

[0138] The fourth insulating portion 1400 in the display module 000 is located at least on the outer surface of the first panel portion 110 where the panel bending portion 130 is not provided, and on the outer surface of the first functional layer 700. For example, the fourth insulating portion 1400 can be insulating adhesive, and this insulating adhesive is applied by dispensing to at least the outer surface of the first panel portion 110 where the panel bending portion 130 is not provided, and on the outer surface of the first functional layer 700. Here, for better viewing... Figure 11The structure of the display panel 100 is as follows: Figure 11 The fourth insulating portion 1400, located on the outer side of the first panel portion 110 where the panel bending portion 130 is not provided, and on the outer side of the first functional layer 700, is not shown.

[0139] It should be noted that, as Figure 11 As shown, the outer side of the panel bending portion 130 in the first panel portion 110 is connected to the panel bending portion 130, preventing negative charges on the surface of the cover plate 200 from entering the display panel 100 from the outer side of the panel bending portion 130 in the first panel portion 110. Furthermore, the distances between the first panel portion 110, the panel bending portion 130, the second panel portion 120, and the cover plate 200 are small. Therefore, negative charges on the surface of the cover plate 200 can easily enter the display panel 100 from the outer side of the first panel portion 110 where the panel bending portion 130 is not located. The fourth insulating portion 1400 located on the outer side of the first panel portion 110 where the panel bending portion 130 is not located effectively prevents negative charges that spread along the surface of the cover plate 200 from being conducted to the outer side of the first panel portion 110 where the panel bending portion 130 is not located. This prevents the display panel 100 from exhibiting a full-screen green tint, resulting in a better display effect.

[0140] Furthermore, during the bonding process of the cover plate 200 and the polarizer 710, the optical adhesive layer 720 in the first functional film layer 700 overflows and comes into contact with the outer surface of the first panel portion 110. Therefore, the fourth insulating portion 1400 is also located on the outer surface of the first functional layer 700. In this way, even if the overflowed portion of the optical adhesive layer 720 comes into contact with the outer surface of the first panel portion 110, the negative charge that moves and diffuses along the surface of the cover plate 200 will not be conducted to the first panel portion 110 through the overflowed portion of the optical adhesive layer 720. As a result, the display panel 100 will not exhibit a greenish tint across the entire screen, thus improving the display effect of the display panel 100.

[0141] In this embodiment of the application, the display module 000 may further include: a second functional film layer 800 located on the side of the first panel portion 110 away from the cover plate 200, and a conductive functional layer 300 located on the second functional film layer 800 away from the first panel portion 110.

[0142] Here, the second functional film layer 800 in the display module 000 may include a first support layer 810 and a polyimide film layer 820. The first support layer 810 in the second functional film layer 800 can be bonded to the side of the display panel 100 opposite to the display side, and the first support layer 810 can be used to support the display panel 100. The polyimide film layer 820 in the second functional film layer 800 is located between the first support layer 810 and the conductive functional layer 300, so that the first support layer 810 and the conductive functional layer 300 are electrically insulated.

[0143] Among them, such as Figure 10 As shown, the fourth insulating portion 1400 is also located on the outer surface of the second functional layer 800 where the panel bending portion 130 is not arranged, and on the outer surface of the conductive functional layer 300 where the panel bending portion 130 is not arranged. It should be noted that if negative charges diffuse along the surface of the cover plate 200 enter the first support layer 810, the negative charges in the first support layer 810 can enter the display panel 100, causing the light-emitting devices in the display panel 100 to become brighter, resulting in a green screen phenomenon. Therefore, since the fourth insulating portion 1400 is also located on the outer surface of the second functional layer 800 where the panel bending portion 130 is not arranged, negative charges will not be conducted to the first panel portion 110 through the first support layer 810 in the second functional layer 800, and the display panel 100 will not exhibit a green screen phenomenon, resulting in a better display effect for the display panel 100.

[0144] Furthermore, the fourth insulating portion 1400 is also located on the outer surface of the non-arranged panel bending portion 130 in the conductive functional layer 300. The fourth insulating portion 1400 can contact the side of the polyimide film layer 820 opposite to the first support layer 810. Since the polyimide film layer 820 also has insulating properties, the probability of negative charges entering the display panel 100 from the outer surface of the non-arranged panel bending portion 130 in the first panel portion 110 is further reduced. The possibility of the display panel 100 exhibiting a greenish tint across the entire screen is lower, resulting in a better display effect for the display panel 100.

[0145] It should also be noted that the display module 000 further includes: a second support layer 1500 and a support pillar 1600 located between the second panel portion 120 and the conductive functional layer 300, and a metal support layer 1700 located on the side of the second functional layer 800 facing away from the first panel portion 110. The second support layer 1500 can be used to support the second panel portion 120; the support pillar 1600 can be used to bond the metal support layer 1700 and the second support layer 1500, and to support the conductive functional layer 300 and the second support layer 1500; the metal support layer 1700 can be used to support the first panel portion 110.

[0146] In summary, the display panel provided in this application includes: a display panel, a cover plate, a first functional film layer, and a fourth insulating portion. The display panel includes: a first panel portion and a second panel portion disposed opposite to each other, and a panel bending portion for connecting the first panel portion and the second panel portion; the first functional film layer is located between the first panel portion and the cover plate. The outer side of the first panel portion where the panel bending portion is located is connected to the panel bending portion, preventing negative charges on the cover plate surface from entering the display panel from the outer side of the first panel portion where the panel bending portion is located. Furthermore, the distances between the first panel portion, the panel bending portion, the second panel portion, and the cover plate are small; therefore, negative charges on the cover plate surface can easily enter the display panel from the outer side of the first panel portion where the panel bending portion is not located. The fourth insulating portion located on the outer side of the first panel portion where the panel bending portion is not located effectively prevents negative charges that spread along the surface of the cover plate from being conducted to the outer side of the first panel portion where the panel bending portion is not located, thus preventing the display panel from exhibiting a full-screen green tint and resulting in a better display effect. Furthermore, during the bonding process between the cover plate and the polarizer in the first functional film layer, the optical adhesive layer used for bonding the cover plate and polarizer overflows and comes into contact with the outer surface of the first panel portion. Therefore, the fourth insulating portion is also located on the outer surface of the first functional layer. In this way, even if the overflowed optical adhesive layer comes into contact with the outer surface of the first panel portion, the negative charge that moves and diffuses along the surface of the cover plate will not be conducted to the first panel portion through the overflowed optical adhesive layer. The display panel will not exhibit a greenish tint across the entire screen, resulting in a better display effect.

[0147] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers.
