The present invention relates to the technical field of screen protectors for mobile phones, specifically a violet blue gradient color, blue light resistant and full-screen tempered privacy screen protectors.
Currently, owing to popularization and intelligentization of mobile phones, many important data such as payment passwords, and personal photos, are stored in the mobile phones, therefore, people are paying more and more attention on their phone privacy, so that privacy screen protectors are in need to satisfy requirements of users.
In the prior fabrication processes, privacy and blue light resistance effects are achieved by coating a layer of blue light resistant film over the privacy layer, which is of low fabrication efficiencies and a high defective rate. Furthermore, privacy screen protectors currently available are black translucent films, microlouver technology used in privacy screen protectors makes actual viewing effects subject to influences of surrounding environments, so that actual effects are very different from expectation, and fabrication processes are complex and of low efficiencies. What's more, when viewing from either side, the privacy protection film products appear to be black, and as a result, demands to screen protection films of different colors could not be met.
Traditional violet blue gradient color films are made by superimposing two or more resins of different refraction indices for more than 100 layers by fusing and extruding to be composite plastic films. As there are fusion and extrusion processes during fabrication, partial mixing and fusion among different fused masses of resins is liable to occur, interlayer refraction index differences of the violet blue gradient colors are reduced.
Targeting at deficiencies of the prior fabrication processes, the present invention provides a violet blue gradient color, blue light resistant and full-screen tempered privacy screen protector, which addresses the problems that spy-proof effects of existing mobile phone screen protectors are not satisfactory and fabrication methods thereof are quite complex and low efficient.

Wherein the composite violet blue gradient and blue light resistant layer comprises a violet blue gradient film and a blue light resistant film.
Wherein fabrication processes of the screen protector are as following:
step S1: coating the violet blue gradient film over the blue light resistant film with a laminating machine to form a composite violet blue gradient and blue light resistant layer;
step S2: bonding the composite violet blue gradient and blue light resistant layer with the spy-proof layer with the laminating machine by an optical clear adhesives (OCA);
step S3: bonding a semi-product obtained in step (S2) respectively with the silk screen reinforcing layer, the flexible explosion-proof layer, the tempered coating, the diamond explosion-proof layer and the electroplated oleophobic layer to form a tempered film;
step S4: cutting the semi-product obtained in step (S3) to be different dimensions into different phone sizes with a laser machine; and
step S5: changing a backplane, putting the product into a defoamer to clear bubbles and completing bonding of the product.
