Description

Technical Field

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

[0002] MiniLED technology has become a hot topic in LCD displays as a backlight source. Unlike traditional LCDs that use a side-lit backlight with a light guide plate, it uses a large number of MiniLED chips as the backlight source for the module. This not only allows for thinner backlights but also enables more precise dynamic control, improving the dynamic contrast of the LCD display. MiniLED technology is expected to become the mainstream trend in the next two years, with significant development potential in the application market.

[0003] The backlight structure may include a back plate, multiple lamp panels and multiple reflectors. The back plate includes a base plate and multiple side plates. The edges of the side plates are connected to the base plate. The multiple side plates and the base plate cooperate to form an accommodating space. The lamp panels are lamp panels with MiniLED chips. The multiple lamp panels can be fixed to the side of the base plate facing the accommodating space. The side of the lamp panel away from the base plate needs to be attached with reflectors. Reflectors also need to be attached to the inner walls of the side plates of the back plate.

[0004] During backlight assembly, the lamp panel and reflector can be supplied as a single unit. This means the reflector is already attached to the lamp panel at the lamp panel factory, the lamp panel is then fixed to the base plate, and finally, the reflector is attached to the side panels. The reflector requires cutting and bonding during the attachment process. When there are many lamp panels, the cost of cutting and bonding the reflector is high, and the overall efficiency of attaching the reflector is low. Utility Model Content

[0005] This application provides a reflective sheet and a display device, wherein the reflective sheet can reduce production costs and improve production efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A reflective sheet, comprising:

[0008] A reflective sheet body, the reflective sheet body having a first side surface and a second side surface that are opposite to each other;

[0009] An anti-adhesion coating is located on a first side of the reflective sheet body, and the anti-adhesion coating is used to prevent adhesion.

[0010] An adhesive portion is located on the second side surface of the reflective sheet body.

[0011] The reflective sheet in the above technical solution has the following beneficial effects: it includes a reflective sheet body, an anti-adhesion coating, and an adhesive part. Since the anti-adhesion coating is located on the first side of the reflective sheet body and the adhesive part is located on the second side of the reflective sheet body, when multiple reflective sheets are stacked, the anti-adhesion coating of the reflective sheet can prevent the reflective sheet from sticking to other reflective sheets, which facilitates the transportation of the reflective sheet. In addition, the absence of a release film on the reflective sheet can reduce the production cost of the reflective sheet. When assembling the reflective sheet into the backlight, it is not necessary to peel off the release film; it can be directly pasted through the adhesive part, which can improve the production efficiency of the backlight.

[0012] In some embodiments of this application, the anti-adhesion coating is a release agent coating.

[0013] The reflective sheet in the above technical solution has the following beneficial effects: the release agent coating on the reflective sheet can provide a temporary adhesive support surface for the adhesive part, so that it can be firmly pasted on the reflective sheet and can be easily, cleanly and controllably peeled off when needed, without damaging the performance of the adhesive part itself.

[0014] In some embodiments of this application, the adhesive portion is an adhesive coating portion or double-sided adhesive.

[0015] The reflective sheet in the above technical solution has the following beneficial effects: the adhesive part can be a glued part, which can be formed by applying glue to the reflective sheet body, or the adhesive part can also be double-sided adhesive, which can be directly attached to the second side of the reflective sheet body. The structure is simple and easy to manufacture.

[0016] In some embodiments of this application, the anti-adhesion coating is a silicone oil release agent coating, and the adhesive portion is an acrylic adhesive portion.

[0017] The reflective sheet in the above technical solution has the following beneficial effects: the silicone oil release agent does not react with the material of the reflective sheet body, which can ensure the function of the reflective sheet; when the adhesive part is the acrylic coating part and comes into contact with the silicone oil release agent coating, silicone transfer is not likely to occur, thus avoiding the reaction between the adhesive part and the anti-adhesion coating and ensuring the function of the reflective sheet.

[0018] In some embodiments of this application, a plurality of adhesive portions are included, which are distributed dispersedly on the reflective sheet body.

[0019] The reflective sheet in the above technical solution has the following beneficial effects: multiple adhesive parts can be distributed on the reflective sheet body, and the adhesive parts can be arranged without forming a whole layer, which can save the material of the adhesive parts and reduce the manufacturing cost.

[0020] In some embodiments of this application, the anti-adhesion coating is doped with a light-diffusing material.

[0021] The reflective sheet in the above technical solution has the following beneficial effects: the anti-adhesion coating can be doped with light-uniforming materials, which can improve the light uniformity of the reflective sheet, improve the optical properties of the reflective sheet surface, and improve the uniformity of backlight emission.

[0022] Some embodiments of this application include:

[0023] Multiple through holes, wherein the through holes penetrate at least through the reflective sheet body and the anti-adhesion coating.

[0024] The reflective sheet in the above technical solution has the following beneficial effects: when the reflective sheet is pasted onto the lamp board, the through holes on the reflective sheet can correspond one-to-one with the LED chips on the lamp board. The LED chips can pass through the corresponding through holes, so that the LED chips on the lamp board are exposed from the reflective sheet, which facilitates the LED chips on the lamp board to emit light.

[0025] In some embodiments of this application, the reflective sheet body includes:

[0026] Part One;

[0027] A plurality of second portions are arranged around the first portion, with adjacent second portions being disconnected;

[0028] The anti-adhesion coating covers the first portion and the plurality of second portions;

[0029] The adhesive portion is disposed on the first portion and the second portion;

[0030] The plurality of through holes are provided on the first part.

[0031] The reflector in the above technical solution has the following beneficial effects: The reflector body includes a first part and multiple second parts. The first part has a through hole and can be attached to the lamp plate through an adhesive part. The light-emitting unit on the lamp plate can pass through the through hole and be exposed from the through hole. The second part can be attached to the inner wall of the side plate of the back plate. In this way, the reflector on the lamp plate and the reflector on the side plate are designed as an integral unit, which can reduce the number of times the reflector is attached and improve the attachment efficiency of the reflector.

[0032] This application also provides a display device, including any of the reflective sheets provided in the above-described technical solutions.

[0033] The reflective sheet in the above technical solution has the following beneficial effects: The reflective sheet includes a reflective sheet body, an anti-adhesion coating, and an adhesive part. Since the anti-adhesion coating is located on the first side of the reflective sheet body and the adhesive part is located on the second side of the reflective sheet body, when multiple reflective sheets are stacked, the anti-adhesion coating of the reflective sheet can prevent the reflective sheet from sticking to other reflective sheets, which facilitates the transportation of the reflective sheet. In addition, the absence of a release film on the reflective sheet can reduce the production cost of the reflective sheet. When assembling the reflective sheet into the backlight, it is not necessary to peel off the release film; it can be directly pasted through the adhesive part, which can improve the production efficiency of the backlight.

[0034] Some embodiments of this application include:

[0035] The back panel includes a bottom plate and multiple side plates, the side plates being connected to the edges of the bottom plate, and the multiple side plates cooperating with the bottom plate to form a receiving cavity;

[0036] At least one light panel is located on a first side of the base plate, the first side being the side of the base plate facing the receiving cavity, and the side of the light panel facing away from the base plate has multiple light-emitting units;

[0037] At least one reflector is located on the side of the lamp panel opposite to the base plate;

[0038] Wherein, when the reflector body of the reflector sheet includes a first part and a plurality of second parts, the first part is bonded to the lamp plate by an adhesive part, the through holes on the at least one reflector sheet correspond one-to-one with the light-emitting units, the light-emitting units pass through the corresponding through holes, and the second part is bonded to the inner wall of the side plate by an adhesive part.

[0039] The reflective sheet in the above technical solution has the following beneficial effects: the absence of a release film on the reflective sheet can save production costs and improve production efficiency. Furthermore, the integrated design of the reflective sheet, with the first part of the reflective sheet body bonded to the lamp plate on the base plate via an adhesive part and the second part of the reflective sheet body bonded to the side plate via an adhesive part, can reduce the number of times the reflective sheet is bonded and improve the bonding efficiency of the reflective sheet.

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] In related technologies, such as Figure 1 As shown, taking the backlight of a 75-inch display device (television) as an example, the backlight has a back panel 01 and 10 lamp panels 02. The back panel 01 has a base plate 011 and 4 side plates 012. The 10 lamp panels 02 are set on the base plate 011 of the back panel. The reflective sheets on the lamp panels 02 are integrally formed with the lamp panels 02, that is, 10 reflective sheets are required on the lamp panels 02, and the 4 side plates also require 4 reflective sheets, so the number of reflective sheets is relatively large.

[0062] During the production of reflective sheets, reflective sheets of the same specification (03) can be cut in batches, such as... Figure 2 As shown, an adhesive layer 04 is provided on the back of the reflector 03. The side of the adhesive layer 04 facing away from the reflector 03 needs to be covered with a release film 05. Multiple reflectors 03 can be stacked for transportation. The release film 05 can prevent the reflectors 03 from sticking together when stacked. The release film 05 is expensive, and a large amount of release film 05 needs to be torn off when assembling the reflectors in the backlight, resulting in low production efficiency of the backlight.

[0063] To address the aforementioned technical problems, embodiments of this application provide a reflective sheet, such as... Figure 3 and Figure 4 As shown, it includes:

[0064] The reflector body 1 has a first side and a second side that are opposite to each other.

[0065] Anti-adhesion coating 2 is located on the first side of the reflective sheet body 1 and is used to prevent adhesion.

[0066] Adhesive part 3 is located on the second side of the reflective sheet body 1.

[0067] The reflective sheet provided in this embodiment includes a reflective sheet body 1, an anti-adhesion coating 2, and an adhesive part 3. Since the anti-adhesion coating 2 is located on the first side of the reflective sheet body 1 and the adhesive part 3 is located on the second side of the reflective sheet body 1, when multiple reflective sheets are stacked, the anti-adhesion coating 2 of the reflective sheet can prevent the reflective sheet from sticking to other reflective sheets, which facilitates the transportation of the reflective sheet. In addition, the absence of a release film on the reflective sheet can reduce the production cost of the reflective sheet. When assembling the reflective sheet into the backlight, it is not necessary to peel off the release film; it can be directly pasted through the adhesive part 3, which can improve the production efficiency of the backlight.

[0068] Specifically, when a batch of reflective sheets are stacked, the anti-adhesion coating 2 of the reflective sheet can contact the adhesive portion 3 of the reflective sheet above it, which can prevent the reflective sheet from sticking to the reflective sheet above it, and facilitate the transportation of the reflective sheets. When assembling the reflective sheets, a reflective sheet can be removed and assembled onto the lamp panel or back panel through the adhesive portion 3 of the reflective sheet.

[0069] Specifically, the thickness of the anti-adhesion coating 2 is not limited here and depends on the actual situation. The thickness of the adhesive portion 3 is also not limited here and depends on the actual situation.

[0070] Specifically, the material of the reflective sheet body 1 can be PET (polyethylene terephthalate). The thickness of the reflective sheet is typically in the range of 100 micrometers to 250 micrometers. The first side of the reflective sheet body 1 can be microbeaded or foamed to form a diffuse reflection structure, avoiding hot spots caused by specular reflection.

[0071] Alternatively, the material of the reflective sheet body 1 can also be other materials, such as PC (polycarbonate) or PEN (polyethylene naphthalate), etc. There are no restrictions here, and it depends on the actual situation.

[0072] Specifically, the material of the anti-adhesion coating 2 does not chemically react with the material of the reflective sheet body 1, thus ensuring the function of the reflective sheet.

[0073] In addition, the material of the adhesive part 3 does not chemically react with the material of the reflective sheet body 1 and the material of the anti-adhesion coating 2, thus ensuring the function of the reflective sheet.

[0074] In the reflective sheet provided in this application embodiment, the anti-adhesion coating 2 can be a release agent coating or other anti-adhesion coatings. There are no restrictions here, and it depends on the actual situation.

[0075] Specifically, the release agent is applied to the surface of the reflective sheet body 1, and after curing, it forms a low surface energy, non-adhesive coating. This coating forms the release agent coating on the first side of the reflective sheet body 1. The release agent coating on the reflective sheet provides a temporary adhesive support surface for the adhesive part 3, allowing it to be firmly adhered to the reflective sheet and easily, cleanly, and controllably peeled off when needed, without damaging the performance of the adhesive part 3 itself.

[0076] In the reflective sheet provided in this application embodiment, the adhesive part 3 can be an adhesive coating part or double-sided adhesive, which has a simple structure and is easy to manufacture.

[0077] Specifically, the adhesive part 3 can be an adhesive coating part, which can be formed by applying glue to the reflective sheet body 1. The structure is simple and easy to manufacture.

[0078] Alternatively, the adhesive part 3 can also be double-sided adhesive, which is directly attached to the second side of the reflective sheet body 1 to form a simple structure that is easy to manufacture.

[0079] Specifically, the anti-adhesion coating 2 can be a silicone oil release agent coating, which is formed by coating the reflective sheet body 1 with a silicone oil release agent.

[0080] Among them, silicone release agent is a special coating material with organosilicon as the core component. It has a low cost and its core function is to give the substrate (reflective sheet body 1) controllable peeling performance. The silicone release agent coating can enable it to achieve the effect of "easy adhesion and easy peeling" with the adhesive part 3.

[0081] When the silicone oil-based release agent is applied to the first side of the reflective sheet body 1, it can form a cured rubber layer, which is the key function of controllable peeling of the adhesive part 3.

[0082] In addition, the silicone oil-based release agent does not react with the material of the reflective sheet body 1, which ensures the effectiveness of the reflective sheet.

[0083] Specifically, to prevent the adhesive portion 3 from reacting with the anti-adhesion coating 2 and to ensure the function of the reflective sheet, the material of the adhesive portion 3 can be a non-silicone adhesive, such as acrylic adhesive, commonly known as water-based adhesive, which is resistant to high and low temperatures and has a wide range of applications. That is, the adhesive portion 3 can be an acrylic coating portion formed by coating acrylic adhesive onto the reflective sheet body 1. When the acrylic coating portion comes into contact with the silicone release agent coating, silicone transfer is less likely to occur.

[0084] Alternatively, the adhesive portion 3 can also be double-sided adhesive. The double-sided adhesive does not react with the silicone release agent. The reflective sheet provided in this application embodiment may include a single layer of adhesive portion 3, such as... Figure 3 As shown.

[0085] For example, an acrylic adhesive can be applied to the second side of the reflective sheet body 1, or a double-sided adhesive can be pasted onto the second side of the reflective sheet body 1.

[0086] Optionally, such as Figure 4 and Figure 5 As shown, the reflective sheet may also include multiple adhesive portions 3, which can be distributed on the reflective sheet body 1. The adhesive portions 3 can be arranged in a non-overlay manner, which can save the material of the adhesive portions 3 and reduce manufacturing costs.

[0087] For example, when the adhesive part 3 is an adhesive coating part, multiple adhesive parts 3 on the reflective sheet can be formed by applying adhesive to multiple areas; or, when the adhesive part 3 is a double-sided adhesive, multiple adhesive parts 3 on the reflective sheet can be formed by attaching multiple small pieces of double-sided adhesive to the reflective sheet body 1.

[0088] Specifically, the orthographic projection shape of the adhesive part 3 on the reflective sheet body 1 can be a strip, a circle, a rectangle, or other shapes. There are no restrictions here, and it depends on the actual situation.

[0089] In the reflective sheet provided in the embodiments of this application, such as Figure 6 As shown, the anti-adhesion coating 2 can be doped with light-uniforming materials, which can improve the light uniformity of the reflector, improve the optical properties of the reflector surface, and improve the uniformity of backlight emission.

[0090] Specifically, the light-diffusing material may include silicon dioxide and / or titanium dioxide, or it may be other materials or combinations of materials. There are no restrictions here, and it depends on the actual situation.

[0091] The reflective sheet provided in the embodiments of this application, such as Figure 7 As shown, it may also include multiple through holes 4, which at least penetrate the reflective sheet body 1 and the anti-adhesion coating 2.

[0092] When the reflective sheet is attached to the lamp board, the through holes 4 on the reflective sheet can correspond one-to-one with the LED chips on the lamp board. The LED chips can pass through the corresponding through holes 4, so that the LED chips on the lamp board are exposed from the reflective sheet, which facilitates the LED chips on the lamp board to emit light.

[0093] Specifically, the multiple through holes 4 can be arranged in an array on the reflective sheet, or they can be arranged in other ways. There are no restrictions here, and it depends on the actual situation.

[0094] Specifically, when the adhesive portion 3 on the reflective sheet is provided as a single layer, such as Figure 8 and Figure 9 As shown, the through hole 4 can penetrate the reflector body 1, the anti-adhesion layer and the adhesive part 3, so that when the reflector is attached to the back plate, the LED chip on the lamp board passes through the through hole 4.

[0095] Alternatively, when the adhesive portion on the reflector is dispersed across the reflector, such as... Figure 10 and Figure 11 The through hole 4 can penetrate the reflective sheet body 1 and the anti-adhesion coating 2, and multiple adhesive parts 3 can be provided on the reflective sheet in areas where the through hole 4 is not provided.

[0096] In the reflective sheet provided in the embodiments of this application, such as Figure 5 As shown, the through hole 4 can be omitted on the reflective sheet, and the reflective sheet with this structure can be used to attach to the side plate of the back plate.

[0097] Optionally, such as Figures 7 to 11 As shown, multiple through holes 4 can also be provided on the reflector. This type of reflector can be attached to a lamp panel. One reflector can cover one or more lamp panels; there is no limitation here, and it depends on the actual situation.

[0098] Optionally, in the reflective sheet provided in the embodiments of this application, such as Figure 12 As shown, the reflective sheet body 1 may include a first part 11 and a plurality of second parts 12, the plurality of second parts 12 being arranged around the first part 11, and adjacent second parts 12 being disconnected; as Figure 13 As shown, the anti-adhesion coating 2 covers the first part 11 and a plurality of second parts 12; the adhesive part 3 is disposed on the first part 11 and the second part 12; a plurality of through holes 4 may be disposed on the first part 11.

[0099] In the aforementioned reflector, the reflector body 1 includes a first part 11 and multiple second parts 12. The first part 11 has a through hole 4. The first part 11 can be attached to the lamp plate through the adhesive part 3. The light-emitting unit on the lamp plate can pass through the through hole 4 and protrude from the through hole 4. The second parts 12 can be attached to the inner wall of the side plate of the back plate. In this way, the reflector on the lamp plate and the reflector on the side plate are designed as an integral unit, which can reduce the number of times the reflector is attached and improve the attachment efficiency of the reflector.

[0100] Specifically, the number of the second part 12 on the reflective sheet body 1 is not limited and depends on the actual situation. For example, as Figure 12 and Figure 13 As shown, the first part 11 of the reflective sheet body 1 is rectangular in shape, and three second parts 12 can be provided on the reflective sheet body 1; or, as shown... Figure 14 and Figure 15 As shown, four second parts 12 can also be provided on the reflective sheet body 1.

[0101] In this embodiment of the application, the manufacturing process of the reflective sheet can be as follows:

[0102] First, a roll of reflective sheet body 1 is provided; then, a silicone release agent is printed and coated on one side of the reflective sheet body 1; then, the coated reflective sheet body 1 roll is cut; next, acrylic adhesive is screen-printed on the other side of the cut reflective sheet body 1 to form a reflective sheet; then, the reflective sheets are neatly placed in positioning posts so that the reflective sheets are stacked; finally, the reflective sheets are packaged and transported.

[0103] Before screen printing acrylic glue on the other side of the cut reflective sheet body 1, it is necessary to prepare a screen printing stencil for applying the glue in advance.

[0104] This application also provides a display device, including any of the reflective sheets provided in the above-described technical solutions.

[0105] In the display device provided in this application embodiment, the reflective sheet includes a reflective sheet body, an anti-adhesion coating, and an adhesive part. Since the anti-adhesion coating is located on the first side of the reflective sheet body and the adhesive part is located on the second side of the reflective sheet body, when multiple reflective sheets are stacked, the anti-adhesion coating of the reflective sheet can prevent the reflective sheet from sticking to other reflective sheets, which facilitates the transportation of the reflective sheet. Furthermore, the absence of a release film on the reflective sheet can reduce the production cost of the reflective sheet. When assembling the reflective sheet into the backlight, it is not necessary to peel off the release film; it can be directly pasted through the adhesive part, which can improve the production efficiency of the backlight.

[0106] Specifically, such as Figure 16 and Figure 17 As shown, the display device includes a back plate 200, at least one lamp plate, and at least one reflector 100. The back plate includes a base plate and multiple side plates. The side plates are connected to the edges of the base plate, and the multiple side plates cooperate with the base plate to form a receiving cavity. At least one lamp plate is located on a first side of the base plate, which is the side of the base plate facing the receiving cavity. The side of the lamp plate away from the base plate has multiple light-emitting units. The reflector is located on the side of the lamp plate away from the base plate.

[0107] In one possible implementation, multiple lamp panels can be mounted on the base plate, and each lamp panel can be fitted with a reflective sheet having through holes through which the light-emitting units on the lamp panel pass and protrude from the reflective sheet. Each side panel can also be fitted with a reflective sheet without through holes. When attaching each reflective sheet, there is no need to peel off a release film; the sheet is directly attached through its adhesive layer, which reduces the production cost of the reflective sheets and improves their attachment efficiency.

[0108] The light panel and the reflector on the light panel can be supplied as a single piece, and the reflector on the light panel can be attached to the light panel in advance at the factory.

[0109] In another possible implementation, multiple light panels can be provided on the base plate. The light panels and reflective sheets can be supplied separately and assembled separately. One reflective sheet can be attached to multiple light panels, which can reduce the number of times the reflective sheet is attached and improve the attachment efficiency of the reflective sheet.

[0110] For example, the base plate of the backlight has 10 light panels, and two reflective sheets can be attached to the 10 light panels. The orthographic projection of the two reflective sheets covers the 10 light panels. This can reduce the number of times the reflective sheets are attached, improve the attachment efficiency of the reflective sheets, and thus improve the production efficiency of the backlight.

[0111] In another possible implementation, when the reflector body of the reflector includes a first part and a plurality of second parts, the first part can be bonded to the lamp plate by an adhesive part, at least one through hole on the reflector corresponds one-to-one with a light-emitting unit, and the light-emitting unit passes through the corresponding through hole, and the second part is bonded to the inner wall of the side plate by an adhesive part.

[0112] In the aforementioned display device, no release film is provided on the reflector, which can save production costs and improve production efficiency. Furthermore, the reflector is designed as an integral piece, with the first part of the reflector body bonded to the lamp plate on the base plate via an adhesive part, and the second part of the reflector body bonded to the side plate via an adhesive part. This reduces the number of times the reflector is bonded and improves the bonding efficiency of the reflector.

[0113] For example, such as Figure 16 As shown, the display device may include two reflective sheets. The reflective sheet body of each reflective sheet may include a first part and three second parts. The edges of the first parts of the two reflective sheets may overlap. The first part may be bonded to multiple lamp panels on the base plate, and the second part may be bonded to the side plate, thereby realizing the assembly of the reflective sheets in the backlight.

[0114] Or, such as Figure 17 As shown, the display device may also include a reflector. The reflector body of each reflector may include a first part and four second parts arranged around the first part. The first part of the reflector body can be bonded to multiple lamp panels, and the four second parts can be bonded to four side panels respectively, which can reduce the number of times the reflector is bonded and improve the bonding efficiency of the reflector.

[0115] Specifically, the arrangement of the through holes on the part where the reflector is attached to the lamp board can be determined according to the arrangement of the light-emitting units on the lamp board. The light-emitting units on the lamp board can be arranged in an array or in other forms, and there are no restrictions here.

[0116] The light-emitting unit is an LED light-emitting chip.

[0117] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
