Description

Technical Field

[0001] This utility model relates to the field of electronic products, specifically to a narrow-bezel shockproof display screen. Background Technology

[0002] The existing product has double-sided adhesive tape at the tail of the backlight to fix the light guide plate to the iron frame. In order to allow space for the expansion of the light guide plate when it is heated during operation, there is no double-sided adhesive tape at the head. The existing gap between the light guide plate and the frame will cause the light guide plate to swing, resulting in scratches and white spots on the light guide plate. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing displays are prone to scratches and white spots during micro-drop tests.

[0004] The technical solution adopted to solve the technical problem proposed by this utility model is as follows: The heat dissipation-facilitating component of this utility model includes a frame, a backlight module, a display module, an LED light board, a back frame, and fasteners. The upper part of the frame is provided with a display module mounting groove, and the display module is located in the display module mounting groove. The backlight module includes a backlight film and a light guide plate. The light guide plate is located inside the back frame, the backlight film is located on the light guide plate, and the LED light board is located on the side of the light guide plate. The frame is a ring structure with a notch. The back frame has an inverted U-shaped bending structure corresponding to the notch. The inner side of the frame and the back frame form a backlight module mounting groove, and the backlight module is located in the backlight module mounting groove. The LED light board is located in the inverted U-shaped bending structure. The inner side of the frame near the LED light board has protrusions on both sides, and the end of the protrusion away from the LED light board has a slope. The distance between the protrusion and the light guide plate is 0.13mm~0.18mm.

[0005] The technical solutions that further define this utility model include:

[0006] The angle between the inclined plane and the frame is less than ten degrees.

[0007] The overlap between the boss and the light guide plate is 3mm ± 0.5mm.

[0008] The height of the protrusion is 0.05mm to 0.1mm lower than the top surface of the light guide plate.

[0009] The back frame is made of metal and is integrally formed with the plastic frame.

[0010] The fastener is a U-shaped frame, one side of which is snapped into the display module and the other side is snapped into the back frame.

[0011] The beneficial effects of this utility model through the above technical solution are as follows: The inner side of the frame of the narrow bezel shockproof display screen of this utility model is provided with protrusions on both sides near the LED light board, and the end of the protrusion away from the LED light board is provided with an inclined surface. The distance between the protrusion and the light guide plate is 0.13mm~0.18mm, which reduces the vibration amplitude of the light guide plate in the micro-drop test, thereby maintaining the friction between the backlight materials and reducing the scratches or white spots that occur in the micro-drop test of the product.

[0014] Figure 3 for Figure 2 A magnified structural diagram of point A in the middle. Detailed Implementation

[0015] The structure of this utility model will be further described below with reference to the accompanying drawings.

[0016] Reference Figures 1 to 3 The narrow-bezel shockproof display screen of this utility model includes a frame 1, a backlight module 2, a display module 3, an LED light board 4, a back frame 5, and fasteners 6. The upper part of the frame 1 is provided with a display module mounting groove 11, and the display module 3 is located within the display module mounting groove 11. The backlight module 2 includes a backlight film 21 and a light guide plate 22. The light guide plate is located inside the back frame, the backlight film is located on the light guide plate, and the LED light board is located on the side of the light guide plate. The frame 1 is an annular structure with a notch 12. The back frame 5 has an inverted U-shaped bending structure 51 corresponding to the notch. The inner side of the frame and the back frame form a backlight module mounting groove 7, and the backlight module is located within the backlight module mounting groove. The LED light board is located within an inverted U-shaped bent structure. The inner side of the frame 1, near the LED light board, has protrusions 13 on both sides. The end of the protrusion furthest from the LED light board has a bevel 131, which facilitates the insertion and assembly of the light guide plate. The distance between the protrusion and the light guide plate is 0.13mm to 0.18mm. This protrusion design reduces the gap between the frame and the light guide plate while allowing for expansion space when the light guide plate is heated during operation. This reduces the vibration amplitude of the light guide plate during micro-drop testing, thus maintaining friction between the backlight materials and reducing scratches or white spots that may appear during micro-drop testing.

[0017] In this embodiment, the angle between the bevel and the frame is less than ten degrees. This facilitates the smooth insertion of the light guide plate during installation, making the installation of the light guide plate easier.

[0018] In this embodiment, the overlap between the boss and the light guide plate is 3mm ± 0.5mm, thereby ensuring the installation gap between the light guide plate and the frame, preventing the vibration amplitude of the light guide plate during the micro-drop test, and ensuring that the light guide plate has room for expansion when heated during operation.

[0019] In this embodiment, the height of the boss is 0.05mm to 0.1mm lower than the top surface of the light guide plate. This does not affect the installation of the backlight film above the backlight panel.

[0020] In this embodiment, the back frame is made of metal and is integrally formed with the plastic frame, which facilitates the installation of the back frame and the plastic frame, makes the connection between the back frame and the plastic frame more secure, prevents the gap between the light guide plate and the plastic frame from increasing due to vibration between the back frame and the plastic frame during the micro-drop test, and reduces the scratches or white spots that may occur in the micro-drop test of the product.

[0021] In this embodiment, the fastener is a U-shaped frame, with one side of the U-shaped frame engaging with the display module and the other side engaging with the back frame. This ensures a secure overall installation.

[0022] When the display screen is tested without the small protrusions, the gap between the light guide plate and the frame is 0.3mm. In the micro-drop test, the height is 10cm, with 100 drops per side for each of the six sides, three cycles per side, for a total of 1800 drops. The front and back sides are each tested with 500 drops for three cycles, for a total of 3000 drops. The total is 4800 drops. After completing 1800 drops, white spots appeared during the client's side micro-drop test.

[0023] Adding small protrusions reduced the gap between the light guide plate and the frame, thus reducing the intensity of friction between the film material and the light guide plate in the micro-drop test. The micro-drop height was 10cm, with 100 drops on each of the six sides (three cycles), totaling 1800 drops. The front and back sides each underwent 500 drops (three cycles), totaling 3000 drops. A total of 4800 drops were performed. No adverse feedback was received after completing 4800 drops.

[0024] Although specific embodiments of the present invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of the present invention. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of the present invention.
