Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a display screen and a television set. Background Technology

[0002] As living standards improve, people are buying larger televisions. During the transportation of large-screen televisions, scratches are a common problem. The main cause of these scratches is the contact between the polarizer and the screen's polarizing film. Currently, the film and diffuser plate are typically assembled by adhesive-backed diffusion plates, with the film secured by mounting ears on the back plate. Films secured in this way are subjected to a downward force. Because the film is relatively thin and soft, it is prone to bending under pressure. Therefore, the film will wrinkle and bend under its own weight, causing the film to come into contact with the screen's polarizer at the wrinkled areas. During television transportation, the film will continuously rub against the polarizer, ultimately resulting in screen scratches. Utility Model Content

[0052] In the description of this embodiment, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0053] As a specific embodiment of this utility model, such as Figures 1-4 As shown, this embodiment discloses a display screen 100, which may include a screen body 110, a diffuser plate 120, a film 130, and a first adhesive layer 140. The diffuser plate 120 is located behind the screen body 110. The film 130 is located between the diffuser plate 120 and the screen body 110. The first adhesive layer 140 is disposed between the diffuser plate 120 and the film 130, and is located near the upper edge of the film 130, so as to adhere the upper edge of the film 130 to the diffuser plate 120.

[0054] Specifically, in this embodiment, the terms front, back, top, bottom, left, right, inside, and outside are for ease of description and do not limit the structure. In this embodiment, the side of the display screen 100 facing the user is called front, and the side facing away from the user is called back. When the user views the display screen 100, and the display screen 100 is placed normally, the top in the vertical direction is top, the bottom is bottom, and the left and right in the horizontal direction are left and right. The middle position of the display screen 100 is inside, and the outward edge is outside.

[0055] Specifically, the display screen 100 in this embodiment may include a screen body 110, a diffuser plate 120, a film 130, and a first adhesive layer 140. The screen body 110, the film 130, and the diffuser plate 120 are arranged sequentially from front to back. The first adhesive layer 140 is disposed between the film 130 and the diffuser plate 120, and is located near the upper side of the film 130, thereby adhering the upper side of the film 130 to the diffuser plate 120. Since the diffuser plate 120 is relatively thick and has high hardness, it bends less under force. Because the film 130 is adhered to the diffuser plate 120, the film 130 will not wrinkle or bend under force. Therefore, the display screen 100 will not rub against the polarizer on the rear side of the screen body 110 during transportation, thereby avoiding damage to the screen body 110. Furthermore, since the film 130 does not wrinkle or bend, the distance between the screen body 110 and the film 130 can be appropriately reduced without affecting the visual effect, thereby reducing the thickness of the display screen 100 and ultimately reducing the overall thickness of the device, making the device more aesthetically pleasing.

[0056] Preferably, in this embodiment, the first adhesive layer 140 is elongated and extends in the left-right direction of the diaphragm 130.

[0057] The long strip-shaped first adhesive layer 140 can be used to attach the upper part of the membrane 130 to the diffuser plate 120, thereby minimizing the wrinkles and bends of the membrane 130.

[0058] The first adhesive layer 140 can be VHB adhesive (Very High Bond Tape). VHB adhesive has high-strength bonding, good weather resistance, and excellent fatigue resistance. Furthermore, VHB adhesive is a pressure-sensitive adhesive, making it easy to apply; bonding can be achieved quickly by simply applying pressure. In addition, the surface after bonding with VHB adhesive is smooth, without visible mechanical fasteners or glue residue, providing a clean and neat appearance that meets the aesthetic requirements of modern design.

[0059] As a specific embodiment of this utility model, the display screen 100 of this embodiment may further include a back plate 150 and a second adhesive layer 160. The back plate 150 is disposed on the side of the diffuser plate 120 away from the diaphragm 130. The second adhesive layer 160 is disposed between the back plate 150 and the diffuser plate 120, and is located near the upper edge of the diffuser plate 120, so as to adhere the upper edge of the diffuser plate 120 to the back plate 150.

[0060] Specifically, in this embodiment, the diffuser plate 120 is adhered to the back plate 150 via the second adhesive layer 160, which reduces the shaking of the diffuser plate 120 during transportation, thereby reducing the shaking of the diaphragm 130 and reducing wear on the screen body 110. Furthermore, the second adhesive layer 160 is located above the diffuser plate 120, which allows the diffuser plate 120 to be flattened, preventing it from bending or deforming due to excessive external pressure.

[0061] Specifically, the second adhesive layer 160 in this embodiment may include a plurality of adhesive units 161, which are spaced apart in the left and right directions of the diffuser plate 120.

[0062] Preferably, the adhesive units 161 are evenly spaced in the left-right direction above the diffuser plate 120, and the even arrangement can improve the overall adhesive stability.

[0063] Furthermore, in this embodiment, forming the second adhesive layer 160 into multiple adhesive units 161 simplifies the adhesive process and improves efficiency.

[0064] The second adhesive layer 160 can be VHB adhesive (Very High Bond Tape). VHB adhesive has high-strength bonding, good weather resistance, and excellent fatigue resistance. Furthermore, VHB adhesive is a pressure-sensitive adhesive, making it easy to apply; direct pressure is sufficient for rapid bonding. In addition, the surface after bonding with VHB adhesive is smooth, with no visible mechanical fasteners or glue residue, providing a clean and neat appearance that meets the aesthetic requirements of modern design.

[0065] In a specific embodiment of this utility model, the upper side, left side, and right side of the back panel 150 all include a first mounting portion 151. The first mounting portion 151 includes a first plate 152, a second plate 153, and a third plate 154 connected in sequence. The front side of the first plate 152 is adhered to the second adhesive layer 160 to mount the diffuser plate 120 and the diaphragm 130. The second plate 153 extends outward from the first plate 152. The third plate 154 extends from the second plate 153 toward the center of the back panel 150, and the rear side of the third plate 154 abuts against the diaphragm 130.

[0066] Specifically, in this embodiment, the first mounting part 151 can mount the diffuser plate 120 and the diaphragm 130 together with the back plate 150. The first mounting part 151 forms a first plate 152, a second plate 153 and a third plate 154. On the one hand, the rear side of the diffuser plate 120 is mounted through the first plate 152, the outer side of the diaphragm 130 is mounted through the third plate 154, and the second plate 153 wraps around the outer side of the diffuser plate 120 and the diaphragm 130, which can play a protective role.

[0067] More specifically, in this embodiment, the second plate 153 is perpendicular to the first plate 152, and the third plate 154 is parallel to the first plate 152. In this embodiment, the first plate 152 and the third plate 154 are parallel to each other and parallel to the diffuser plate 120 and the membrane 130, while the second plate 153 is perpendicular to the diffuser plate 120 and the membrane 130. Of course, in this embodiment, parallelism or perpendicularity is not absolute; a difference of up to 5 degrees between the two plates can be considered as parallelism or perpendicularity.

[0068] As a specific embodiment of the present invention, the display screen 100 of this embodiment may further include a sealing member 170, which is disposed between the third plate 154 located on the upper side and the diaphragm 130.

[0069] Specifically, the sealing element 170 in this embodiment is selected from rubber strips or PU foam. By providing the sealing element 170 between the third plate 154 and the template, on the one hand, the movement of the diaphragm 130 in the front-back direction can be restricted, reducing the possibility of the diaphragm 130 hitting the polarizer on the rear side of the screen body 110. On the other hand, it can block foreign objects, preventing foreign objects from entering between the diaphragm 130 and the diffuser plate 120, or preventing foreign objects from entering between the diffuser plate 120 and the back plate 150.

[0070] As a specific embodiment of the present invention, the display screen 100 of this embodiment may further include a middle frame 180, which is connected to the screen body 110 and the back panel 150.

[0071] Specifically, the mid-frame 180 is connected to the screen body 110 and the back panel 150, and together with the back panel 150, it supports the screen body 110, the membrane 130, and the diffuser plate 120. Generally, the mid-frame 180 is located on the outer edge of the screen body 110 and the back panel 150, which can protect the screen body 110, the membrane 130, and the diffuser plate 120, and can wrap around the outer periphery of the screen body 110, the back panel 150, the membrane 130, and the diffuser plate 120, thereby improving the aesthetics of the entire display screen 100.

[0072] Specifically, in this embodiment, the upper, left, and right sides of the middle frame 180 can each include a frame body 181 and a second mounting portion 182. The frame body 181 is disposed on the outer side of the screen body 110 and the back panel 150. The second mounting portion 182 extends inward from the frame body 181 to between the screen body 110 and the third plate 154. The front side of the second mounting portion 182 is connected to the screen body 110, and the rear side of the second mounting portion 182 is connected to the third plate 154.

[0073] Specifically, in this embodiment, the mid-frame 180 is designed with a frame body 181 and a second mounting portion 182. The frame body 181 is located on the outside of the screen body 110 and the back panel 150, protecting the screen body 110 and the back panel 150 while improving the aesthetics of the outside. The second mounting portion 182 extends inward from the frame body 181 between the screen body 110 and the third plate 154, increasing the connection area between the second mounting portion 182 and the screen body 110, and also increasing the mounting area between the second mounting portion 182 and the back panel 150, making the installation of the mid-frame 180 with the screen body 110 and the back panel 150 more secure.

[0074] Specifically, the display screen 100 in this embodiment may include a third adhesive layer 190, which is disposed between the second mounting part 182 and the screen body 110 to mount the screen body 110 and the middle frame 180 together.

[0075] The display screen 100 in this embodiment may include a fourth adhesive layer 191, which is disposed between the second mounting part 182 and the third plate 154 to mount the back plate 150 and the middle frame 180 together.

[0076] In this embodiment, both the third adhesive layer 190 and the fourth adhesive layer 191 are double-sided adhesive. Preferably, the third adhesive layer 190 and the fourth adhesive layer 191 cover the entire second mounting portion 182 to maximize the adhesive area.

[0077] As a specific embodiment of the present invention, the middle frame 180 of this embodiment may further include a blocking part 183, which is connected to the side of the second mounting part 182 away from the frame 181 and extends rearward from the second mounting part 182, and the side of the blocking part 183 away from the second mounting part 182 is close to the diaphragm 130.

[0078] Specifically, in this embodiment, the blocking portion 183 extends from the second mounting portion 182 toward the diaphragm 130, which can initially prevent the diaphragm 130 from jumping toward the screen body 110, thereby reducing the friction between the diaphragm 130 and the screen body 110. The inclined design of the blocking portion 183 in this embodiment is due to process limitations.

[0079] Specifically, such as Figure 5 As shown, the screen body 110 generally includes an outer black border area 111 and an inner visible area 112, with the blocking part 183 within the black border area 111.

[0080] Specifically, in this embodiment, the blocking part 183 is located inside the third plate 154 and also inside the second mounting part 182. When the blocking part 183 is within the black border area 111, it will not affect the display effect of the visible area 112.

[0081] As a specific embodiment of the present utility model, the frame 181 of this embodiment may include a first frame 184 extending forward from the second mounting part 182. The side of the first frame 184 away from the second mounting part 182 is flush with the front side of the screen body 110, or the side of the first frame 184 away from the second mounting part 182 is located in front of the front side of the screen body 110.

[0082] Specifically, in this embodiment, the front side of the first frame 184 is designed to be flush with the plane of the screen body 110 or to protect the screen body 110 on the front side of the plane of the screen body 110.

[0083] Specifically, in this embodiment, the inner side 185 of the first frame 184 is an inclined surface, and the angle α formed between the inclined surface and the plane containing the front side of the second mounting part 182 is an obtuse angle.

[0084] This design facilitates the installation of the screen body 110 from the front side of the first frame 184 into the inside of the first frame 184, and then attaches it to the second mounting part 182.

[0085] Specifically, in this embodiment, the included angle α formed between the inclined surface and the plane containing the front side of the second mounting part 182 ranges from 95° to 100°. In this embodiment, the included angle α can be 95°, 96°, 97°, 98°, 99°, 100°, etc. If the included angle α is too small, it will not facilitate installation; if the angle is too large, the top will be too sharp, making manufacturing impossible and difficult to control.

[0086] Specifically, the frame 181 in this embodiment may further include a second frame 186 extending rearward from the second mounting portion 182, the second frame 186 wrapping around the outside of the second plate 153. In this embodiment, the side of the back plate 150 is protected by the second frame 186 wrapping around the outside of the second plate 153.

[0087] As a specific embodiment of the present invention, this embodiment also discloses a television set, which may include a display screen 100.

[0088] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
