[0051] 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.

[0052] This application provides a display device. Please refer to Figures 1 and 2. Figure 1 is a structural schematic diagram of a display device provided in this application, and Figure 2 is a partial enlarged view of a display device without a display panel and a blocking structure provided in this application. The display device may include: a back plate 100, a frame 200, a display panel 300, and a blocking structure 400.

[0053] The edge portion of the back panel 100 in the display device can be snapped into the frame 200. The edge portion of the display panel 300 in the display device can be connected to the side of the frame 200 opposite to the back panel 100. The frame 200 in the display device may include two first frame borders 201 and two second frame borders 202 arranged opposite to each other. The extending direction of the first frame borders 201 may intersect the extending direction of the second frame borders 202.

[0054] Here, the extension direction of the first border 201 can be parallel to the first direction X, and the extension direction of the second border 202 can be parallel to the second direction Y. The first direction X can intersect the second direction Y; for example, the first direction X can intersect the second direction Y perpendicularly. Thus, the two first borders 201 can be positioned opposite each other in the second direction Y, and the two second borders 202 can be positioned opposite each other in the first direction X. It should be noted that the two first borders 201 can be the top and bottom borders of the display device, respectively, and the two second borders 202 can be the left and right borders of the display device, respectively.

[0055] The end face of the first frame 201 in the frame 200 can face the side of the second frame 202, and a first gap M1 can be formed between the end face of the first frame 201 and the side of the second frame 202. Here, the two end faces of the first frame 201 in the first direction X can respectively face the two second frames 202, and a first gap M1 can be formed between the two end faces of the first frame 201 and the two second frames 202. Here, the first gap M1 communicates with the space enclosed by the back panel 100, the frame 200, and the display panel 300.

[0056] It should be noted that the frame 200 and the back panel 100 are not perfectly sealed. There is a third gap M3 between the first frame 201 and the back panel 100, and there is also a third gap M3 directly between the second frame 202 and the back panel 100. One end of the third gap M3 is connected to the outside, and the other end is connected to the first gap M1. In the prior art, dust from the external environment can easily enter the space between the display panel 200 and the back panel 100 through the third gap M3 and the first gap M1. That is, dust enters the interior of the display device, which may interfere with the operation of the display device and reduce the safety of its use.

[0057] In this application, as shown in Figures 3 and 4, Figure 3 is a partially enlarged view of a display device without a display panel according to an embodiment of this application, and Figure 4 is a cross-sectional view of a display device with a display panel according to an embodiment of this application at point A-A'. A blocking structure 400 in the display device can be sandwiched between the frame 200 and the display panel 100. The blocking structure 400 can be distributed at the end positions of the first frame 201 and / or the end positions of the second frame 202. Here, the blocking structure 400 can block dust from the external environment to prevent dust from entering the space enclosed by the back plate 100, the frame 200, and the display panel 300 through the first gap M1, ensuring that dust will not interfere with the normal operation of the display device, thus making the display device safer to use.

[0058] In summary, this application provides a display device including a back panel, a frame, a display panel, and a blocking structure. A first gap exists between the end face of the first frame and the side face of the second frame of the frame, and the first gap communicates with the space enclosed by the back panel, the frame, and the display panel. The blocking structure in the display device can be distributed at the end positions of the first frame and / or the end positions of the second frame. In this way, the blocking structure can block dust from the external environment, preventing dust from entering the space enclosed by the back panel, the frame, and the display panel through the first gap, thus ensuring that dust will not interfere with the normal operation of the display device and making the display device safer to use.

[0059] Optionally, as shown in FIG5, which is a partial enlarged view of another display device without a display panel provided in an embodiment of this application, the blocking structure 400 may include a first blocking block 401. The first blocking block 401 of the blocking structure 400 may be distributed at the end position of the first frame 201, and the first blocking block 401 may cover at least a portion of the first gap M1. In this way, the first blocking block 401 covering the first gap M1 can prevent dust from entering the space enclosed by the back plate 100, the display panel 300, and the frame 200 through the first gap M1. Here, the first blocking block 400 may include a portion located on the first frame 201 and a portion covering the first gap M1.

[0060] It should be noted that the side of the first blocking block 401 facing the second frame 402 can abut against the second frame 402 to ensure that the first blocking block 401 can completely cover the first gap M1 in the extending direction of the first blocking block 401, thereby further ensuring that dust will not enter the space enclosed by the back panel 100, the display panel 300 and the frame 200 through the first gap M1.

[0061] It should also be noted that the third gap M3 between the frame 200 and the back panel 100 can be the gap between the frame 200 and the back panel 100 in a direction parallel to the display surface of the display panel 300. Here, the third gap M3 between the first frame 201 and the back panel 100 can be the gap between the first frame 201 and the back panel 100 in the second direction Y.

[0062] The portion of the first blocking block 401 located on the first frame 201 can block dust from entering the third gap M3, thereby reducing the possibility of dust entering the first gap M1. The portion of the first blocking block 401 covering the first gap M1 can prevent dust from entering the space enclosed by the back panel 100, display panel 300, and frame 200 through the first gap M1. Thus, the first blocking block 401 can block dust from entering the third gap M3, reducing the possibility of dust entering the first gap M1, and also prevent dust from entering the space enclosed by the back panel 100, display panel 300, and frame 200 through the first gap M1. Therefore, by setting the first blocking block 401, dust can be prevented from entering the space enclosed by the back panel 100, display panel 300, and frame 200.

[0063] Optionally, as shown in Figures 4 and 5, the display device may further include an adhesive strip 500 for connecting the edge portions of the frame 200 and the display panel 300. The adhesive strip 500 may include a first adhesive strip 501 for connecting the first frame 201 and the display panel 300. The first adhesive strip 501 may have a clearance groove S at its end near the second frame 202, and a portion of the first blocking block 401 may be located within the clearance groove S of the first adhesive strip 501. Here, the clearance groove S of the first adhesive strip 501 serves a positioning function. When assembling the first blocking block 401 within the display device, the assembly position of the first blocking block 401 can be obtained through the clearance groove S of the first adhesive strip 501, facilitating the assembly of the first blocking block 401 within the display device.

[0064] Optionally, as shown in Figures 5 and 6, Figure 6 is a partial enlarged view of another display device without a display panel provided in an embodiment of this application. The outer edge of the frame 200 of the display device can have a limiting protrusion 210. The limiting protrusion 210 located on the outer edge of the first frame 201 can be a first limiting protrusion 2011, and the side of the first blocking block 401 facing away from the first adhesive strip 501 can abut against the first limiting protrusion 2011 of the first frame 201.

[0065] It should be noted that the outer edge of the back plate 100 also has a protrusion 110. The third gap M3 between the first frame 201 and the back plate 100 can be the gap between the first limiting protrusion 2011 and the protrusion 110 of the back plate 100. In this way, the portion of the first blocking block 401 located on the first frame 201 can block dust from entering the third gap M3.

[0066] Optionally, as shown in Figures 5 and 6, the blocking structure 400 may further include a second blocking block 402. The second blocking block 402 in the blocking structure 400 may be distributed at the end positions of the second frame 202. The adhesive strip 500 may further include a second adhesive strip 502 for connecting the second frame 202 and the display panel 300. The second blocking block 402 may be located on the side of the second adhesive strip 502 facing away from the first frame 201.

[0067] It should be noted that the third gap M3 between the second frame 202 and the back panel 100 can be the gap between the second frame 202 and the back panel 100 in the first direction X. The second blocking block 402 located on the second frame 202 can block dust from entering the third gap M3, thereby further reducing the possibility of dust entering the first gap M1. In this way, by setting the first blocking block 401 and the second blocking block 402, dust entering the third gap M3 between the frame 200 and the back panel 100 can be blocked, thereby reducing the possibility of dust entering the first gap M1, and preventing dust from entering the space enclosed by the back panel 100, the display panel 300 and the frame 200 through the first gap M1.

[0068] It should be noted that when assembling the second blocking block 402 into the display device, it is only necessary to align the end of the second blocking block 402 with the end of the second frame 202.

[0069] Optionally, as shown in Figure 6, the limiting protrusion 210 on the outer edge of the second frame 202 can be a second limiting protrusion 2021, and the side of the second blocking block 402 facing away from the second adhesive strip 502 can abut against the second limiting protrusion 2021. It should be noted that the third gap M3 between the second frame 202 and the back plate 100 can be the gap between the second limiting protrusion 2021 and the protrusion 110 of the back plate 100. In this way, the second blocking block 402 can block dust from entering the third gap M3.

[0070] In this application, the first blocking block 401 and the second blocking block 402 can be sponges, which can absorb dust to prevent dust from entering the space enclosed by the back panel 100, the display panel 300, and the frame 200 through the first gap M1. Here, the first blocking block 401 and the second blocking block 402 can each have adhesive backing on the side facing the frame 200, so that the first blocking block 401 can be directly adhered to the first frame 201, and the second blocking block 402 can be directly adhered to the second frame 202.

[0071] In this application, as shown in Figures 5 and 6, the length of the first blocking block 401 in the first direction X can be greater than the distance between the groove surface of the first adhesive strip 501 in the first direction X and the second frame 202. Specifically, the length of the first blocking block 401 in the first direction X can be greater than the distance between the groove surface of the first adhesive strip 501 in the first direction X and the second adhesive strip 502 located on the second frame 202. This ensures that the two ends of the first blocking block 401 in the first direction X have a good contact effect with the first adhesive strip 501 and the second adhesive strip 502, respectively, thereby making the first blocking block 401 have a good covering effect on the first gap M1.

[0072] Furthermore, the width of the first blocking block 401 in the second direction Y can be greater than the distance between the groove surface of the first adhesive strip 501 in the second direction Y and the first limiting protrusion 2011. This ensures that the two ends of the first blocking block 401 in the second direction Y have a good contact effect with the first adhesive strip 501 and the second adhesive strip 502, respectively.

[0073] Furthermore, the height of the first blocking block 401 in the direction perpendicular to the display surface of the display panel 300 can be greater than the distance between the first frame 201 and the display panel 300 in the direction perpendicular to the display surface of the display panel 300. This ensures that the first blocking block 401 has a good contact effect with the first frame 201 and the display panel 300 on both sides in the direction perpendicular to the display surface of the display panel 300.

[0074] For example, the distance between the first bezel 201 and the display panel 300 in the direction perpendicular to the display surface of the display panel 300 can be 1.3 mm. The height of the first blocking block 401 in the direction perpendicular to the display surface of the display panel 300 can be 2 mm.

[0075] It should be noted that when the first frame 201 is a top-side frame, the distance between the clearance groove S of the first adhesive strip 501 in the first direction X and the second adhesive strip 502 can be 18.9 mm, and the length of the first blocking block 401 on the top-side frame in the first direction X can be 20 mm. The distance between the clearance groove S of the first adhesive strip 501 in the second direction Y and the first limiting protrusion 2011 can be 6.75 mm, and the width of the first blocking block 401 on the top-side frame in the second direction Y can be 7 mm.

[0076] When the first frame 201 is a ground-side frame, the distance between the clearance groove S of the first adhesive strip 501 and the groove surface of the second adhesive strip 502 in the first direction X can be 18.99 mm, and the length of the first blocking block 401 located on the top-side frame in the first direction X can be 20 mm. The distance between the clearance groove S of the first adhesive strip 501 and the groove surface of the first limiting protrusion 2011 in the second direction Y can be 4.27 mm, and the width of the first blocking block 401 located on the top-side frame in the second direction Y can be 5.5 mm.

[0077] Similarly, as shown in Figures 5 and 6, the width of the second blocking block 402 in the first direction X can be greater than the distance between the second adhesive strip 502 and the second limiting protrusion 2021 in the first direction X. This ensures that the two ends of the second blocking block 401 in the first direction X have a good contact effect with the second adhesive strip 502 and the second limiting protrusion 2021, respectively. For example, the distance between the second adhesive strip 502 and the second limiting protrusion 2021 in the first direction X can be 4.83 mm, and the width of the second blocking block 402 in the first direction X can be 5.5 mm.

[0078] It should be noted that the length of the second blocking block 402 in the second direction Y is not limited. For example, the length of the second blocking block 402 in the second direction Y can be 20 mm.

[0079] The height of the second blocking block 402 in the direction perpendicular to the display surface of the display panel 300 can be greater than the distance between the second frame 202 and the display panel 300 in the direction perpendicular to the display surface of the display panel 300. This ensures that the two sides of the second blocking block 402 in the direction perpendicular to the display surface of the display panel 300 have a good contact effect with the first frame 201 and the display panel 300, respectively.

[0080] For example, the distance between the second bezel 202 and the display panel 300 in the direction perpendicular to the display surface of the display panel 300 can be 1.3 mm. The height of the second blocking block 402 in the direction perpendicular to the display surface of the display panel 300 can be 2 mm.

[0081] Thus, the display device in this embodiment can include two specifications of sponge blocks. The sponge block located on the first frame 201 (the top-side bezel), i.e., the first blocking block 401 on the first frame 201 (the top-side bezel), can have the following specifications: length 20 mm, width 7 mm, and height 2 mm. The sponge blocks located on the second frame 202 and the first frame 201 (the bottom-side bezel), i.e., the first blocking block 401 on the first frame 201 (the bottom-side bezel) and the second blocking block 402 on the second frame 202, can have the following specifications: length 20 mm, width 5.5 mm, and height 2 mm.

[0082] Optionally, as shown in Figures 7 and 8, and Figures 9 and 10, Figure 7 is a partial enlarged view of another display device without a display panel provided in an embodiment of this application; Figure 8 is a partial enlarged view of the back of a display device provided in an embodiment of this application; Figure 9 is a partial enlarged view of another display device without a display panel provided in another embodiment of this application; and Figure 10 is a partial enlarged view of the back of another display device provided in an embodiment of this application. The frame 200 may have multiple first snap-fit ​​electrodes 220, and the back plate 110 may have multiple second snap-fit ​​electrodes 120. The multiple first snap-fit ​​electrodes 220 of the frame 200 may be snapped into one-to-one correspondence with the multiple second snap-fit ​​electrodes 120 of the back plate 100, and a second gap M2 may exist between the first snap-fit ​​electrode 220 and the corresponding second snap-fit ​​electrode 120.

[0083] The display device may further include a covering structure 600. The covering structure 600 can cover the edges of the frame 200 and the back panel 100, and can cover at least a portion of the second gap M2. In this way, the covering structure 600 can prevent external dust from entering the space enclosed by the back panel 100 and the frame 200 through the second gap M2, thereby preventing dust from entering the space enclosed by the back panel 100, the frame 200, and the display panel 300 through the first gap M1, ensuring the normal operation of the display device.

[0084] In one possible implementation, as shown in Figures 9 and 10, the covering structure 600 can cover the corners of the frame 200 and the back panel 100, that is, the four corners of the display device can be covered by the covering structure 600. Here, the covering structure 600 can cover the second gap M2 between the first latching member 220 and the corresponding second latching member 120 closest to the second frame 202 in the first frame 201, and can also cover the second gap M2 between the first latching member 220 and the corresponding second latching member 120 closest to the first frame 201 in the second frame 202.

[0085] It should be noted that since the first gap M1 between the first frame 201 and the second frame 202 is located between the end of the first frame 201 and the side of the second frame 202, that is, the first gap M1 is located at the corner of the display device, dust entering through the second gap M2 between the first latch 220 and the corresponding second latch 120 closest to the corner of the display device can easily enter the first gap M1. Therefore, after the covering structure 600 covers the second gap M2 between the first latch 220 and the corresponding second latch 120 closest to the corner of the display device, it can greatly reduce the amount of dust entering the space enclosed by the back panel 100, the frame 200 and the display panel 300 through the first gap M1.

[0086] In the second optional implementation, as shown in Figures 11 and 12, Figure 11 is a schematic diagram of another display device provided in an embodiment of this application, and Figure 12 is a partially enlarged view of a ground-side bezel and a second bezel provided in an embodiment of this application. The two first bezels 201 in the display device can be a top-side bezel 201a and a ground-side bezel 201b, respectively. The covering structure 600 in the display device can include a first covering structure 601, a plurality of second covering structures 602, and two third covering structures 603.

[0087] The first covering structure 601 can cover the edges of the top side frame 201a and the back panel 100, and the first covering structure 601 can cover the second gap M2 between each of the first latching members 220 and the corresponding second latching members 120 on the top side frame 201a. Here, the first covering structure 601 can cover the entire edge of the top side frame 201a and the back panel 100. In this way, the first covering structure 601 can prevent dust from entering the first gap M1 through the second gap M2 between each of the first latching members 220 and the corresponding second latching members 120 on the top side frame 201a, further ensuring that dust will not enter the space enclosed by the back panel 100, the frame 200 and the display panel 300 through the first gap M1.

[0088] Multiple second covering structures 602 can cover the edges of the ground side frame 201b and the back panel 100, and multiple second covering structures 6602 can correspond to at least a portion of the first latching members 220 in the ground side frame 201b. The second covering structures 602 can cover the second gap M2 between the corresponding first latching member 220 and the corresponding second latching member 120 in the ground side frame 201b. In this way, the second covering structures 602 can prevent dust from entering the first gap M1 through the second gap M2 between the respective first latching members 220 and the corresponding second latching members 120 on the ground side frame 201b, further ensuring that dust will not enter the space enclosed by the back panel 100, the frame 200 and the display panel 300 through the first gap M1.

[0089] Here, the second covering structure 602 only covers the first latch 220 and the corresponding second latch 120 on the ground side bezel 201b, and does not cover other parts of the ground side bezel 201b. This ensures that the second covering structure 602 will not block the wiring used to connect components located inside and outside the space enclosed by the back panel 100, the frame 200 and the display panel 300 respectively.

[0090] Two third covering structures 603 can respectively cover the edges of the two second frame 202 and the back panel 100, and can cover the second gap M2 between each first latch 220 and the corresponding second latch 120 on the second frame 202. Here, the third covering structure 603 can cover the entire edge of the second frame 202 and the back panel 100. In this way, the third covering structure 603 can prevent dust from entering the first gap M1 through the second gap M2 between each first latch 220 and the corresponding second latch 120 on the second frame 202, further ensuring that dust will not enter the space enclosed by the back panel 100, the frame 200 and the display panel 300 through the first gap M1.

[0091] Optionally, the first end of the third covering structure 603 can be connected to the end of the first covering structure 601. In the first case, the second end of the third covering structure 603 can be connected to the end of the second covering structure 602 closest to the second frame 202. That is, the second gap M2 between the two outermost first latches 220 and the corresponding second latches 120 on the ground side frame 201b can be covered by the portion of the third covering structure 603 extending towards the ground side frame 201a. In the second case, the second end of the third covering structure 603 can be unconnected to the end of the second covering structure 602 closest to the second frame 202. That is, the second end of the third covering structure 603 only covers the ends of the second frame 202 and the back panel 100, and the second gap M2 between the two outermost first latches 220 and the corresponding second latches 120 on the ground side frame 201b can be covered by the two separate second covering structures 602.

[0092] It should be noted that the two corners of the top side frame 201a and the two second frame frames 202 can be simultaneously covered by the first covering structure 601 and the third covering structure 603. The two corners of the bottom side frame 201b and the two second frame frames 202 can be covered by the third covering structure 603, or can be simultaneously covered by the second covering structure 602 and the third covering structure 603.

[0093] It should also be noted that, regardless of whether the covering structure 600 is implemented in the first or second optional manner, the portion of the covering structure 600 used to cover the second gap M2 between the first and second latching members closest to the corner of the display device can also cover the third gap M3 in the frame 200 and back plate 100 near the corner of the display device. Thus, by providing the covering structure 600 at the corner of the display device, the possibility of dust from the external environment entering the first gap M1 through the second gap M2 and the third gap M3 can be greatly reduced. In the second optional manner of the covering structure 600, the covering structure 600 can cover the entire second gap M2, thereby completely preventing dust from the external environment from entering the first gap M1 through the second gap M2, and further reducing the possibility of dust from the external environment entering the first gap M1 through the second gap M2 and the third gap M3.

[0094] In this application, the material of the covering structure 600 can be Mylar, i.e., polyester film. When the covering structure 600 is Mylar, it can be a structure including a first covering structure 601, multiple second covering structures 602, and two third covering structures 603. It should be noted that the thickness of the Mylar covering structure 600 can be 0.05 mm.

[0095] Alternatively, the covering structure 600 can be made of acetate tape. When the covering structure 600 is acetate tape, it can cover the corners of the frame 200 and the back panel 100. It should be noted that the thickness of the acetate tape covering structure 600 can be 0.02 mm. Acetate tape is relatively inexpensive in this case.

[0096] In this application, when the material of the covering structure 600 is Mylar, and the covering structure 600 includes a first covering structure 601, a plurality of second covering structures 602, and two third covering structures 603, the covering structure 600 and the blocking structure 400 assembled on the display device can, to the greatest extent possible, prevent dust from entering the space enclosed by the back plate 100, the frame 200, and the display panel 300 through the first gap M1. In this case, if an acetate tape covering structure 600 is further assembled at the corner of the display device, dust can be further prevented from entering the space enclosed by the back plate 100, the frame 200, and the display panel 300 through the first gap M1.

[0097] It should be noted that, as shown in Figures 7 and 8, in the top bezel 201a and the two second bezels 202, in the extending direction of the frame, the protrusions closest to the corner of the display device are the limiting protrusion of the frame 200 and the corresponding protrusion of the back plate 100, followed by the first latching member 220 and the first latching member 120. Similarly, as shown in Figures 9 and 10, in the bottom bezel 201b, in the extending direction of the bottom bezel 201b, the protrusions closest to the corner of the display device are the first latching member 220 and the first latching member 120. Therefore, compared to the top bezel 201a and the two second bezels 202, the distance between the second gap M2 between the first and second latches closest to the corner of the display device on the ground bezel 201b and the first gap M1 is relatively short. Therefore, dust from the external environment is more likely to enter the first gap M1 through the second gap M2 between the first and second latches closest to the corner of the display device on the ground bezel 201b.

[0098] Therefore, after assembling the Mylar covering structure 600 and the blocking structure 400 on the display device, the acetate covering structure 600 can be assembled on the corners of both ends of the ground side frame 201b in the display device.

[0099] In this application, please refer to FIG13, which is a cross-sectional view of a display device according to an embodiment of this application. Here, the display device shown in FIG13 can be simultaneously assembled with a blocking structure and a Mylar covering structure. The Mylar covering structure 600 may include: a first part 610, a second part 620, a third part 630, and a fourth part 640 connected in sequence; the first part 610 and the third part 630 are arranged opposite to each other in a direction perpendicular to the display surface of the display panel. The first part 610 is located on the side of the back plate 100 away from the frame 200, and the third part 630 is located on the side of the limiting protrusion 210 of the frame 200 and the protrusion 110 of the back plate 100 away from the first part 610. The second part 620 and the fourth part 630 are arranged opposite each other on the display surface parallel to the display panel and perpendicular to the extension direction of the frame. The second part 620 is located on the side of the back plate 100 where the protrusion 100 is away from the limiting protrusion 210 of the frame 200, and the fourth part 640 is located on the side of the limiting protrusion 210 of the frame 200 where the protrusion 100 is away from the back plate 100. This ensures that the Mylar covering structure 600 can completely cover the second gap M2 between the first snap-fit ​​member on the frame 200 and the second snap-fit ​​member on the back plate 100, ensuring that dust from the external environment will not enter the second gap M2.

[0100] As shown in FIG14, which is an exploded view of a display device provided in an embodiment of this application, the display device may further include a front frame 700, a light source component 800, and a rear component 900. The front frame 900 in the display device may be located on the side of the display panel 300 away from the back plate 100. The front frame 900 may block the non-display area of ​​the display panel 300, so that the display area of ​​the display panel 300 is located within the space enclosed by the front frame 900.

[0101] The light source component 800 in the display device can be located between the display panel 300 and the back plate 100, and can be located within the space enclosed by the frame 200. Here, the light source component 800 can be a direct-lit light source, and the light emitted by the light source component 800 can be directed towards the display panel 300, enabling the display panel 300 to display an image. It should be noted that the blocking structure 400 and the covering structure 600 in the above embodiment can prevent dust from the external environment from entering the space enclosed by the back plate 100, the display panel 300, and the frame 200, thereby preventing dust from affecting the light source component 800.

[0102] The light source component 800 may include a light strip 801, a reflective paper 802, and an optical element 803 arranged sequentially along the back plate 100 toward the display panel 300. The light strip 801 has multiple LEDs arranged in an array, which emit light. The reflective paper 802 has multiple openings corresponding one-to-one with the LEDs. The light emitted by the LEDs can pass through the openings to the optical element 803, and then through the optical element 803 to the display panel 300. Areas in the reflective paper 802 without openings can reflect light to improve light utilization. For example, the optical element 803 may include an expansion plate and a film.

[0103] The rear component 900 in the display device can be located on the side of the back panel 100 opposite to the display panel 300. The rear component 900 may include a driving assembly 901, a speaker 902, and a housing 903. The driving assembly 901 can be electrically connected to the lamp strip 801 by bypassing the outer edge of the back panel 100 to drive the lamps on the lamp strip 801 to emit light.

[0104] In summary, this application provides a display device including a back panel, a frame, a display panel, and a blocking structure. A first gap exists between the end face of the first frame and the side face of the second frame of the frame, and the first gap communicates with the space enclosed by the back panel, the frame, and the display panel. The blocking structure in the display device can be distributed at the end positions of the first frame and / or the end positions of the second frame. In this way, the blocking structure can block dust from the external environment, preventing dust from entering the space enclosed by the back panel, the frame, and the display panel through the first gap, thus ensuring that dust will not interfere with the normal operation of the display device and making the display device safer to use.
