[0038] 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.

[0039] This application provides a display device; please refer to the embodiments described herein. Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a display device provided in an embodiment of this application. Figure 2 This is a schematic diagram of a partial structure of a display device provided in an embodiment of this application. Figure 3 This is a partial structural diagram of another display device provided in an embodiment of this application. The display device may include: a back panel 100, a decorative panel 200, a display panel 300, and a first light-shielding component 400.

[0040] The back panel 100 in the display panel may include a back panel body 101 and a first side 102. The first side 102 in the back panel 100 may be fixedly connected to a portion of the outer edge of the back panel body 101. The decorative panel 200 in the display device may be connected to another portion of the outer edge of the back panel body 101.

[0041] Here, the display surface of the display device can be rectangular, and the back panel body 101 in the back panel 100 can have four side edges. The first side edge 102 in the back panel 100 can be connected to three of the four side edges of the back panel body 101, and the decorative panel 200 can be connected to the other side edge of the four side edges of the back panel body 101. It should be noted that the first side edge 102 located at the three side edges of the back panel body 101 and the back panel body 101 can be an integrally formed structure.

[0042] The decorative panel 200 in the display device may have a second side 201. The end of the second side 201 of the decorative panel 200 may be spliced ​​with the end of the first side 102 of the back panel 100, and the first side 102 of the back panel 100 and the second side 201 of the decorative panel 200 may form a setting area K. The side of the first side 102 of the back panel 100 facing the setting area K may have a buffer block 1021, and the buffer block 1021 may be distributed at least at the end of the first side 102 near the second side 201.

[0043] The display panel 300 in the display device can be connected to one side of the back panel body 101, and the display panel 300 can be located within the setting area K.

[0044] Here, the corner portion of the display panel 300, which is adjacent to the first side 102 of the back panel 100 and the second side 201 of the decorative panel 200, is distributed adjacent to the buffer block 1021 on the side facing the first side 102. In this way, after the display device is impacted, this corner portion of the display panel 300 can contact the buffer block 1021, which has a certain degree of elasticity and can protect the display panel 300. This avoids the display panel 300 from directly impacting the first side 102 and being damaged, thus improving the reliability of the display device.

[0045] During the operation of the display device, the display panel 300 needs to display an image, and light will shine into the setting area K enclosed by the first side 102 and the second side 201. Since the first side 102 located on the three edges of the back panel body 101 and the back panel body 101 are integrally formed, and the decorative panel 200 located on one edge of the back panel body 100 is connected to the back panel 100, the light in the setting area K may leak to the outside through the seam between the decorative panel 200 and the back panel 100. Here, the light in the setting area K mainly leaks to the outside through the seam between the end of the decorative panel 200 and the end of the back panel 100. For example, the end of the second side 201 of the decorative panel 200 and the end of the first side 102 of the back panel 100 are spliced ​​together, and there is a seam between the end of the first side 102 and the end of the second side 201.

[0046] In related technologies, to prevent light within the setting area K from leaking through the edges of the display device, a light-shielding component can be installed at the edge of the first side 102 near the second side 201. This light-shielding component can be located on the side of the first side 102 closest to the setting area K. To ensure good light-shielding effect, the end of the light-shielding component can be tightly fitted to the first side 102. However, because a buffer block 1021 is provided on the first side 102, when the side of the light-shielding component facing the first side 102 is in direct contact with the buffer block 1021, there is always a seam between the side of the light-shielding component facing the first side 102 and the surface of the first side 102 facing the setting area K without the buffer block 1021. This causes light within the setting area K to leak between the end of the light-shielding component and the surface of the first side 102 facing the setting area K, and subsequently leak to the outside through the seam between the end of the decorative panel 200 and the end of the back panel 100.

[0047] In this application, the first light-shielding component 400 in the display device can be distributed on the side of the second side 201 of the decorative panel 200 near the setting area K. The side of the first light-shielding component 400 facing the first side 102 can have a relief groove S1. A portion of the buffer block 1021 can be located within the relief groove S1 of the first light-shielding component 400. The area of ​​the first light-shielding component 400 facing the first side 102 without the relief groove S1 can directly contact the surface of the first side 102 without the buffer block 1021. In this way, the side of the first light-shielding component 400 facing the first side 102 can directly contact both the buffer block 1021 and the surface of the first side 102 without the buffer block 1021, so that the light in the setting area K will not leak between the first light-shielding component 400 and the surface of the first side 102 without the buffer block 1021, thus avoiding edge light transmission of the display device.

[0048] It should be noted that when the display device is a television, after the first light-shielding component 400 is installed inside the television, during the use of the television, if a piece of white paper is placed 10 centimeters away from the seam between the decorative panel 200 and the back panel 100 in a dark environment, the light in the setting area K will not pass through the seam and hit the white paper. This meets the quality requirements of televisions on the market.

[0049] In summary, this application provides a display device including a back panel, a decorative panel, a display panel, and a first light-shielding component. The first light-shielding component in the display device can be distributed on the second side of the decorative panel near the setting area. The side of the first light-shielding component facing the first side can have a relief groove. A portion of the buffer block can be located within the relief groove of the first light-shielding component. Furthermore, the area of ​​the first light-shielding component facing the first side without a relief groove can directly contact the surface of the first side without a buffer block. In this way, the side of the first light-shielding component facing the first side can directly contact both the buffer block and the surface of the first side without a buffer block, preventing light leakage from the setting area between the first light-shielding component and the surface of the first side without a buffer block, thus avoiding edge light transmission of the display device.

[0050] Optional, such as Figure 3 As shown, the first light-shielding component 400 can directly contact the edge portion of the decorative panel 200 distributed in the back panel body 101. That is, the first light-shielding component 400 can be distributed at the edge position of the back panel body 101 facing the second side 201, and the first light-shielding component 400 can directly contact the back panel body 101. In this way, the side of the first light-shielding component 400 facing the first side 102 can directly contact the surface of the first side 102 where the buffer block 1021 is not provided, and the side of the first light-shielding component 400 facing the back panel body 101 can directly contact the back panel body 101, so that the light in the setting area K will not pass through the gap between the first light-shielding component 400 and the first side 102, nor will it pass through the gap between the first light-shielding component 400 and the back panel body 101, thereby preventing light from passing through the edge of the display device.

[0051] It should be noted that the first light-shielding component 400 may have a certain degree of elasticity. For example, the first light-shielding component 400 may be a foam with a certain degree of elasticity. In the direction parallel to the display surface of the display panel 300 and parallel to the length extension direction of the decorative panel 200, the groove depth of the clearance groove S1 on the first light-shielding component 400 may be adapted to the thickness of the buffer block 1021 on the first side 102. Specifically, the groove depth of the clearance groove S1 may be equal to or slightly greater than the thickness of the buffer block 1021.

[0052] When the depth of the clearance groove S1 is equal to the thickness of the buffer block 1021, the groove surface of the clearance groove S1 facing the first side 102 can directly contact the surface of the buffer block 1021. The surface of the first light-shielding member 400 facing the first side 102 without the clearance groove S1 can directly contact the surface of the first side 201 facing the setting area K without the buffer block 1021.

[0053] When the depth of the clearance groove S1 is slightly greater than the thickness of the buffer block 1021, when the groove surface of the clearance groove S1 facing the first side 102 is in direct contact with the surface of the buffer block 1021, the part of the first light-shielding member 400 facing the first side 102 that does not have the clearance groove S1 can be slightly compressed, so that the surface of the first light-shielding member 400 facing the first side 102 that does not have the clearance groove S1 can be in close contact with the surface of the first side 201 facing the setting area K that does not have the buffer block 1021.

[0054] Optional, such as Figure 3 As shown, in a direction perpendicular to the display panel 300, the buffer block 1021 can be distributed at the edge of the first side 102 away from the back panel body 101. The clearance groove S1 of the first light-shielding member 400 can be located on the side of the first light-shielding member 400 away from the back panel body 101.

[0055] Here, the buffer block 1021 is located at the edge of the first side 102 near the second side 201, and is distributed at the edge of the first side 102 away from the back panel body 101. Thus, the buffer block 1021 can be distributed at the corners of the display panel 300 near both the first side 102 and the second side 201 to protect the corners of the display panel 300. The clearance groove S1 of the first light-shielding member 400 is set according to the position and thickness of the buffer block 1021.

[0056] Optional, such as Figure 3 and Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of a first light-shielding component provided in an embodiment of this application. The side of the first light-shielding component 400 opposite to the first side 102 may have an auxiliary clearance groove S2. The auxiliary clearance groove S2 and the clearance groove S1 in the first light-shielding component 400 may be symmetrically distributed on both sides of the first light-shielding component 400.

[0057] It should be noted that the first light-shielding component 400 has adhesive backing on the side facing the setting area K. This adhesive backing allows the first light-shielding component 400 to abut against the support component 500, support plate 1022, and optical diffuser plate 700 in subsequent embodiments. Here, the first light-shielding component 400 only has adhesive backing on the side facing the setting area K. Therefore, the first light-shielding component 400 has a clearance groove S1 and an auxiliary clearance groove S2 at both ends of the decorative plate 200 along its length, so that the two first light-shielding components 400 at both ends of the back plate body 101 can abut against the buffer block 1021 on the side facing the first side 102.

[0058] The auxiliary clearance groove S2 of the first light-shielding component 400 serves as a foolproof feature. When the first light-shielding component 400 is installed inside the display device, since both ends of the first light-shielding component 400 have clearance grooves S1 and auxiliary clearance grooves S2 respectively, either end of the first light-shielding component 400 can contact the first side 102. When the end of the first light-shielding component 400 with the clearance groove S1 contacts the first side 102, a portion of the buffer block 1021 can be located within the clearance groove S1. When the end of the first light-shielding component 400 with the auxiliary clearance groove S2 contacts the first side 102, a portion of the buffer block 1021 can be located within the auxiliary clearance groove S2.

[0059] Optional, such as Figure 5 and Figure 6 As shown, Figure 5 This is a partial structural schematic diagram of another display device provided in an embodiment of this application. Figure 6 This is a partial structural diagram of another display device provided in an embodiment of this application. The first side 102 of the back panel 100 facing the setting area K may have a support plate 1022. The edge portion of the display panel 300 adjacent to the first side 102 may be fixed to the support plate 1022.

[0060] It should be noted that a connecting layer may be present between the support plate 1022 and the display panel 300. The edge portion of the display panel 300 adjacent to the first side 102 can be fixed to the support plate 1022 through the connecting layer.

[0061] It should also be noted that when the display surface of the display device is rectangular, the three edges of the back panel body 101 are each connected to a first side 102, and each of the three first side 102s facing the setting area K has a support plate 1022. The first side 102s on the three edges can be integrally formed, and the support plates 1022 connected to the three first side 102s can also be integrally formed. In this way, light within the setting area K will not pass through the first side 102s and the support plates 1022.

[0062] The display device also includes a support member 500, which can be located on the side of the second side 201 facing the setting area K. The edge portion of the display panel 300 adjacent to the second side 201 is fixed to the support member 500.

[0063] Here, as Figure 5 As shown, since the first side 102 has a support plate 1022 facing the setting area K, the support plate 1022 needs to have a certain width to support the display panel 300 along the length extension direction of the decorative panel 200. Therefore, there is a certain distance between the support member 500 and the first side 102. Light in the setting area K will pass through the space between the support member 500 and the first side 102.

[0064] In this application, as Figure 5 and Figure 6 As shown, the first light-shielding member 400 can be distributed between the support member 500 and the second side 201. The side of the first light-shielding member 400 facing the support member 500 can abut against the support member 500 and can abut against the end of the support plate 1022. In the length extension direction of the decorative plate 200, the distance between the end face of the support member 500 and the first side 102 can be greater than the width of the support plate 1022 and less than the length of the first light-shielding member 400.

[0065] Thus, the support plate 1022 can be located between the support member 500 and the first side 102, and the first light-shielding member 400 can have a certain length to cover the distance between the support member 500 and the first side 102. For this purpose, the first light-shielding member 400 can block the light transmitted from the setting area K between the support member 500 and the first side 102, and prevent light transmission from the edge of the display device.

[0066] Optional, such as Figure 5 and Figure 7 As shown, Figure 7 This is a cross-sectional view of a display device provided in an embodiment of this application. The display device may further include an optical diffuser 700 and a light source component. The edge portion of the optical diffuser 700 in the display device can be fixed to the back plate body 101 and can be distributed within the setting area K. The optical diffuser 700 and the back plate body 101 in the display device can be used to form a receiving cavity P, and the light source component can be fixed within the receiving cavity P. When the display panel 300 in the display device needs to display an image, the light source component can emit light. The light emitted by the light source component can illuminate the display panel 300 after passing through the optical diffuser 700, thereby realizing the light emission of the display panel 300.

[0067] The edge portion of the optical diffuser 700 in the display device that is adjacent to the first side 102 can be located on the side of the support plate 1022 facing away from the display panel 300, that is, the edge portion of the optical diffuser 700 that is adjacent to the first side 102 can be located between the back plate body 101 and the support plate 1022. The edge portion of the optical diffuser 700 in the display device that is adjacent to the second side 201 can be located on the side of the support member 500 facing away from the display panel 300, that is, the edge portion of the optical diffuser 700 that is adjacent to the second side 201 can be located between the support member 500 and the back plate body 101.

[0068] The side of the first light-shielding component 400 facing the support component 500 in the display device can abut against the outer edge of the optical diffuser 700. In this way, when the light passing through the optical diffuser 700 overflows to the edge of the optical diffuser 700, the first light-shielding component 400 can directly block the light overflowing from the side of the optical diffuser 700, further preventing light transmission from the edge of the display device.

[0069] It should be noted that the optical diffuser 700 may include a stacked optical film and an optical diffuser plate. The optical film in the optical diffuser 700 can be closer to the display panel 300 relative to the optical diffuser plate. Light emitted by the light source component located in the receiving cavity P can be directed to the display panel 300 after passing through the optical diffuser plate and the optical film in sequence.

[0070] Optional, such as Figure 7 and Figure 8 As shown, Figure 8 This is a partial structural diagram of a display device according to another embodiment of this application. The decorative panel 200 in the display device may also have a decorative strip 202 connected to the second side 201. The decorative strip 202 in the decorative panel 200 may cover the edge portion of the display panel 300 adjacent to the second side 201, and the end of the decorative strip 202 may be spliced ​​with the end of the first side 102. For example, as... Figure 8 As shown, the end of the decorative strip 202 can be spliced ​​with the end of the first side 102 in a direction perpendicular to the display surface of the display panel 300. In the direction perpendicular to the display surface of the display panel 300, there can be a first seam X1 between the end of the decorative strip 202 and the end of the first side 102.

[0071] It should be noted that by setting the first light-shielding component 400 in the above embodiment, the overall light-blocking standard of display devices on the market can be met. However, when a user specifically observes the first seam X1 from in front of it, the light inside the display device can still be seen from the first seam X1.

[0072] like Figure 7 and Figure 9 As shown, Figure 9 This is a schematic diagram of the structure of a decorative panel provided in an embodiment of this application. The display device may further include a second light-shielding component 600. The second light-shielding component 600 in the display device may be sandwiched between the decorative strip 202 and the display panel 300, and the second light-shielding component 600 may be distributed at the end position of the decorative strip 202 near the first side 102.

[0073] In this way, when the user observes the first seam X1 from the front of the first seam X1, what is seen from the first seam X1 is the second light-blocking component 600, so that the second light-blocking component can block light from passing through the first seam X1.

[0074] Optional, such as Figure 7 and Figure 9 As shown, the decorative panel 200 may also have a buffer strip 203. The buffer strip 203 in the decorative panel 200 may be located on the side of the decorative strip 202 facing the display panel 300. The second light-shielding portion 600 in the display device may include: a first portion 601 and a second portion 602 connected to each other. The first portion 601 of the second light-shielding portion 600 may be connected to the side of the buffer strip 203 away from the decorative strip 202, and the second portion 602 of the second light-shielding portion 600 may be directly connected to the decorative strip 202.

[0075] In this way, the first part 601 of the second light-shielding component 600 sandwiched between the buffer strip 203 and the display panel 300 can fill the seam between the buffer strip 203 and the display panel 300, preventing light in the setting area K from passing through the space between the buffer strip 203 and the display panel 300.

[0076] It should be noted that, during the manufacturing process of the display panel 300 in the display device, due to manufacturing process issues, on the side of the display panel 300 near the decorative panel 200, at the end of the decorative panel 200 along its length, there is an unsealed area between the display panel 300 and the buffer strip 203, which is a seam between the display panel 300 and the buffer strip 203. The first part 601 of the second light-shielding member 600 can block light within the setting area K from passing through this unsealed area.

[0077] It should also be noted that the second light-shielding component 600 is located at the end of the decorative strip 202, and the first part 601 of the second light-shielding component 600 is sandwiched between the end of the buffer strip 203 and the display panel 100. The side of the buffer strip 203 not connected to the second part 601 facing the display panel 300 can directly contact the display panel 300, and the buffer strip 203 can play a buffering role to prevent the decorative strip 202 from damaging the display panel 300.

[0078] Optionally, both the first light-shielding component 400 and the second light-shielding component 600 in the display device can be elastic foam.

[0079] For example, the first light-shielding component 400 can be a contoured EVA foam. It should be noted that when the display device is a large-screen television, the structure of the first side of the television is roughly the same. The structure of the first light-shielding component 400 in this application is adaptable and highly versatile. Moreover, the first light-shielding component 400 occupies little space and does not affect the setting of the internal structure of the first side.

[0080] For example, the second light-blocking component 600 can be E-3008 foam. E-3008 foam has a low density and a large compressibility. The second light-blocking component 600, sandwiched between the decorative strip 202 and the display panel 300, will not compress the display panel 300 and can also provide excellent light-blocking effect. Furthermore, in current television display devices, the end of the decorative strip 202 generally does not have a blocking structure, allowing the E-3008 foam to be attached to the decorative strip 202, thus offering high versatility.

[0081] It should be noted that the decorative panel 200 may deform during the use of the display device. Deformation of the decorative panel 200 causes a change in the distance between the decorative strip 202 and the display panel 300 at the end of the decorative strip 202, which in turn changes the size of the seam between the buffer strip 203 and the display panel 300. Since the second light-shielding member 600 is made of elastic foam, its thickness, sandwiched between the buffer strip 203 and the display panel 300, can increase as the seam between them widens and decrease as the seam narrows. Thus, regardless of how the decorative panel 200 deforms, the seam between the buffer strip 203 and the display panel 300 will always be filled by the second light-shielding member 600, preventing light from passing through between them.

[0082] In this application, as Figure 8 and Figure 9 As shown, an example of splicing the end of the first side 102 in the back panel 100 with the end of the second side 201 in the decorative panel 200 is illustrated. For example, the end of the first side 102 is spliced ​​with the end of the second side 201 in a direction perpendicular to the length extension of the decorative panel 200. Thus, a second seam X2 is formed between the end of the first side 102 and the end of the second side 201 in a direction perpendicular to the length extension of the decorative panel 200.

[0083] The second side 201 of the decorative panel 200, facing the installation area K, may have multiple ribs 2011, which may be distributed at the edge of the second side 201. When a user observes the second seam X2 from the front of the second seam 201, the user can see the ribs 2011. That is, the ribs 2011 can block the light shining towards the second seam X2, preventing light from passing through the second seam X2.

[0084] The display device in this application can be a large-screen television; for example, the display device can be a television of 55 inches or larger. For a large-screen television of 55 inches or larger, the length of the first light-shielding member 400 installed inside the television in the direction parallel to the length extension of the decorative panel 200 can be between 24.8 mm and 25.2 mm, the thickness of the first light-shielding member 400 in the direction perpendicular to the length extension of the decorative panel 200 can be between 1.8 mm and 2.2 mm, the height of the first light-shielding member 400 in the direction perpendicular to the display surface of the display panel 300 can be between 6.8 mm and 7.2 mm, the height of the clearance groove S1 and the auxiliary clearance groove S2 of the first light-shielding member 400 in the direction perpendicular to the display surface of the display panel 300 can be between 1.5 mm and 1.9 mm, and the length of the clearance groove S1 and the auxiliary clearance groove S2 of the first light-shielding member 400 in the direction parallel to the length extension of the decorative panel 200 can be between 1.3 mm and 1.7 mm.

[0085] For large-screen TVs of 55 inches and above, the length of the second light-shielding component 600 installed inside the TV in the direction parallel to the length extension of the decorative panel 200 can be between 19.8 mm and 20.2 mm, the thickness of the second light-shielding component 600 in the direction perpendicular to the display surface of the display panel 300 can be between 1.3 mm and 1.7 mm, and the length of the second light-shielding component in the direction perpendicular to the length extension of the decorative panel 200 can be between 9.8 mm and 10.2 mm.

[0086] In summary, this application provides a display device including a back panel, a decorative panel, a display panel, and a first light-shielding component. The first light-shielding component in the display device can be distributed on the second side of the decorative panel near the setting area. The side of the first light-shielding component facing the first side can directly contact a buffer block and also directly contact the surface of the first side where no buffer block is provided. Thus, the side of the first light-shielding component facing the first side can directly contact both the buffer block and the surface of the first side where no buffer block is provided, preventing light leakage within the setting area from between the first light-shielding component and the buffer block, and also preventing light leakage from between the first light-shielding component and the surface of the first side where no buffer block is provided, thus avoiding edge light transmission of the display device. Furthermore, the second light-shielding component in the display device is sandwiched between the decorative strip of the decorative panel and the display panel, and is distributed at the end of the decorative strip near the first side of the back panel. The second light-shielding component can block light from passing through the edge seam between the back panel and the decorative panel, and can also block light from passing through the seam between the display panel and the decorative panel. Therefore, by setting a first light-blocking component and a second light-blocking component, edge light transmission of the display device can be completely avoided.
