1. A violet blue gradient color, blue light resistant and full-screen tempered privacy screen protector, comprising an electroplated oleophobic layer (1), a diamond explosion-proof layer (2), a tempered coating (3), a flexible explosion-proof layer (4), a silk screen reinforcing layer (5), a composite violet blue gradient and blue light resistant layer (6) and a privacy protection layer (7);
wherein the composite violet blue gradient and blue light resistant layer (6) comprises a violet blue gradient film (61) and a blue light resistant film (62);
wherein fabrication processes of the screen protector are as following:
a first step (S1): coating the violet blue gradient film (61) over the blue light resistant film (62) with a laminating machine to form the composite violet blue gradient and blue light resistant layer (6);
a second step (S2): bonding the composite violet blue gradient and blue light resistant layer (6) with the spy-proof layer (7) with the laminating machine by an optical clear adhesives (OCA);
a third step (S3): bonding a semi-product obtained in the second step (S2) respectively with the silk screen reinforcing layer (5), the flexible explosion-proof layer (4), the tempered coating (3), the diamond explosion-proof layer (2) and the electroplated oleophobic layer (2) to form a tempered film;
a fourth step (S4): cutting the semi-product obtained in the third step (S3) to be different dimensions with a laser machine; and
a fifth step (S5): changing a backplane, putting the product obtained in the fourth step (S4) into a defoamer to clear bubbles and completing bonding of the product.
