Description

Technical Field

[0001] This utility model relates to the field of modules, and in particular to a light-shielding structure for medium and large-sized modules. Background Technology

[0002] The backlight structure for LCDs is generally a glue-and-iron integrated structure, where excess light from the lamp opening is blocked by a light-shielding black strip on the diffuser. However, for medium and large-sized products, due to the increased size, thicker optical films are typically required to prevent wrinkles or other abnormalities on the surrounding surface. As the size increases, the required thickness also increases, which makes the height of the light-shielding black strip on the diffuser insufficient and the gap too large. During operation, to ensure the activation rate of the light-shielding adhesive and the frame surface, pressure is applied to activate the light-shielding adhesive. At this time, the light-shielding adhesive adheres to the light-shielding black strip and FPC, causing the light-shielding adhesive to pull up the light-shielding black strip and FPC, resulting in poor beam in the display area and failing to meet the customer's visual requirements. Utility Model Content

[0003] To address the shortcomings or deficiencies of the existing technology, this utility model provides a light-shielding structure for medium and large-sized modules, which can block excess light beams and achieve a visually uniform effect in the display area. At the same time, the heat-generating element is in direct contact with the well-dissipated iron frame of the component, which is more conducive to heat conduction and heat dissipation. Furthermore, there is no need to attach heat sinks or other heat dissipation materials, thus saving costs.

[0004] A light-shielding structure for medium and large-sized modules includes an iron frame, on which a U-shaped bending frame is fixedly connected. The U-shaped bending frame has a light-shielding groove and a square slot. The U-shaped bending frame has a placement area one and a placement area two. A reflective film is placed on the placement area two of the U-shaped bending frame, and an FPC is placed on the placement area two of the U-shaped bending frame. A light guide plate is placed on the reflective film, and an LED light strip is fixedly connected to one end of the light guide plate. Adhesive is bonded inside the light-shielding groove on the U-shaped bending frame, and a reflective strip is bonded to the adhesive.

[0005] Preferably, the iron frame has a square through hole.

[0006] Preferably, the second placement area on the U-shaped bending frame is 0.5 mm higher than the first placement area.

[0007] Preferably, the FPC passes through the square through hole on the iron frame and the square slot on the U-shaped bending frame.

[0008] Preferably, the LED light strip is located within the light-shielding groove on the U-shaped bending frame.

[0009] The beneficial effects of this utility model are as follows: by closely attaching the reflective strip to the LED light strip, excess light beams are blocked, achieving a visually uniform effect in the display area. At the same time, the heating element is in direct contact with the well-dissipated iron frame, which is more conducive to heat conduction and heat dissipation. Furthermore, there is no need to attach heat sinks or other heat dissipation materials, thus saving costs. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1 A light-shielding structure for medium to large-sized modules, such as Figures 1-3 As shown, it includes an iron frame 1, on which a U-shaped bending frame 2 is fixedly connected. The U-shaped bending frame 2 has a light-shielding groove and a square slot. The U-shaped bending frame 2 has a placement area one and a placement area two. A reflective film 3 is placed on the placement area two of the U-shaped bending frame 2. An FPC 4 is placed on the placement area two of the U-shaped bending frame 2. A light guide plate 5 is placed on the reflective film 3. An LED light strip 6 is fixedly connected to one end of the light guide plate 5. Adhesive 7 is bonded in the light-shielding groove on the U-shaped bending frame 2. A reflective strip 8 is bonded to the adhesive 7.

[0016] The iron frame 1 has a square through hole.

[0017] The second placement area on the U-shaped bending frame 2 is 0.5mm higher than the first placement area.

[0018] The FPC4 passes through the square through hole on the iron frame 1 and the square slot on the U-shaped bending frame 2.

[0019] The LED light strip 6 is located in the light-shielding groove on the U-shaped bending frame 2.

[0020] During assembly, the reflective strip 8 and adhesive 7 are first attached to the upper end of the light-shielding groove on the U-shaped bending frame 2 using a fixture. The reflective film 3 is placed on the second placement area on the U-shaped bending frame 2. The LED light strip 6 is inserted into the light-shielding groove on the U-shaped bending frame 2, so that the reflective strip 8 and the LED light strip 6 are in close contact, which can block excess light beams and achieve a visually uniform effect in the display area. At the same time, the FPC4 is in direct contact with the iron frame 1, which is more conducive to heat conduction and heat dissipation. There is no need to attach heat sinks or other heat dissipation materials, saving costs.
