[0022] 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.
[0023] The present application proposes a cover plate 100 coated with a black film, which is used in the cover plate of a mobile phone. Figure 1 and Figure 2 , including: a cover plate 10 and a black film 20 attached to the cover plate 10. The black film 20 includes four titanium oxide layers 21 and four silicon dioxide layers 22, and the titanium oxide layers 21 and the silicon dioxide layers 22 are cross-stacked. A camera hole is provided on the cover plate 10, and the black film 20 is attached to the surface of the cover plate 10 on the side close to the titanium oxide layer 21. The black film 20 can block the camera installed in the camera hole, so that the user cannot see the camera with the naked eye. The staff simulates the black film 20 with the same color as the back of the cover plate 10 through software to achieve the effect of the same color on the back of the cover plate 10 and improve the aesthetics. The camera can take pictures through a certain refractive index of the black film 20, which does not affect the function of the camera. Preferably, the titanium oxide layer 21 is a titanium oxide layer or a titanium oxide layer.
[0024] In one embodiment, during repair or recycling, the cover plate 10 is removed from the mobile phone, and a card slot is provided at the edge of the cover plate 10. The staff pries the cover plate 10 from the card slot and then removes the cover plate 10 from the mobile phone, thereby improving the efficiency of removing the cover plate 10.
[0025] It should be noted that the black film 20 is plated on the cover plate 10 by ion plating.
[0026] According to people's usage habits, the cover plate 10 is set to a rectangular structure, so the black film 20 is a rectangular structure, so that the black film 20 can completely cover the cover plate 10, and the black film 20 is completely attached to the edge of the cover plate 10 to eliminate color difference.
[0027] Furthermore, the reflectivity of the black film 20 is 60%.
[0028] Furthermore, the transmittance of the black film 20 is 40%.
[0029] In another embodiment, the refractive index of the silicon dioxide layer 22 is 1.55, and the refractive index of the titanium oxide layer 21 is 2.61. The low refractive index of the silicon dioxide layer 22 and the high refractive index of the titanium oxide layer 21 interact with each other, so that the camera can shoot through the black film 20 without affecting the shooting function of the original camera.
[0030] In addition, the thickness of the titanium oxide layer 21 and the silicon dioxide layer 22 ranges from 80 nm to 120 nm. When the titanium oxide layer 21 and the silicon dioxide layer 22 are stacked at different thicknesses, the reflectivity and refractive index also change accordingly. Preferably, the thickness of the titanium oxide layer 21 and the silicon dioxide layer 22 is 90 nm.
[0031] 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.
