[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0024] A protective film structure for the FPC component area of a display screen, referring to Figure 1, including a display screen 10, a FPC 20 is bound to the display screen 10, and a component area 21 is arranged on the FPC 20. The component area 21 is covered with a protective film 30, and the protective film 30 is covered in the component area 21 by spraying.
[0025] Reference Figure 1 and Figure 2 The protective film 30 is an ultraviolet curing coating, which can enhance the moisture and dirt resistance and improve the insulation performance of the component area 21. The protective film 30 is formed by spraying the ultraviolet curing coating onto the component area 21, thereby protecting the component area 21.
[0026] Reference Figure 1 and Figure 2 The thickness of the protective film 30 is less than 0.1 mm. The size of the protective film 30 is adapted to the size of the component area 21 to avoid the size of the protective film 30 being larger than the size of the component area 21 and causing structural interference.
[0027] Reference Figure 2 A circle of protective paper 40 is arranged around the outer periphery of the component area 21 to limit the spraying range of the protective film 30 . The protective paper 40 is arranged along the outer peripheral direction of the component area 21 . The protective paper 40 surrounds the outer periphery of the component area 21 so that the spraying range of the protective film 30 is within the component area 21 .
[0028] Reference Figure 2 The protective paper 40 is a long and thin strip of PET sticker. The protective paper 40 is attached to the periphery of the FPC 20 relative to the component area 21. Before the protective film 30 is sprayed on the component area 21, the protective paper 40 is attached to the periphery of the component area 21, and then a layer of protective film 30 is sprayed within the component area 21, so that the protective film 30 covers all positions of the component area 21. After the spraying is completed, the protective paper 40 is torn off to make the spraying range of the protective film 30 compatible with the size of the component area 21.
[0029] Reference Figure 3 The thickness of the protective film 30 outside the component area 21 is greater than the thickness of the protective film 30 inside the component area 21 . The protective film 30 outside the component area 21 is thickened by spraying so that the components at the edge of the component area 21 are completely covered with the protective film 30 .
[0030] Reference Figure 3The protective film 30 is covered with a waterproof layer 50, which is a nano waterproof coating. The waterproof layer 50 is applied on the protective film 30 and the entire periphery of the component area 21. The waterproof layer 50 can further prevent water vapor from invading the component area 21 and avoid condensation of water vapor to cause a short circuit. The waterproof coating is applied after the protective paper 40 is surrounded by the periphery of the component area 21 and sprayed with the protective film 30. After the waterproof coating is applied, the protective paper 40 is torn off.
[0031] Reference Figure 3 The thickness of the waterproof layer 50 is 0.05mm-0.08mm.
[0032] Reference Figure 3 By spraying the protective film 30 on the component area 21 by spraying, a special-shaped protective film 30 can be realized, which has a stronger adaptability to the shape of the component area 21, reduces the protective film 30 that is pasted by hand and occupies more space, thereby avoiding structural interference, and the protective film 30 is covered with a waterproof layer 50, which can further prevent water vapor from invading the component area 21.
[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
