    TECHNICAL AREA
    The present invention belongs to the technical field of protective films for mobile phones, and more particularly relates to a tempered glass film for a curved surface telephone screen.
    BACKGROUND
    A tempered glass film is a high-tech protective film specifically designed to protect a mobile phone screen. This is a new high-end product that has a relatively strong protective effect on the mobile phone screen and is able to completely cover the original screen surface to increase the absorbency of shocks. more prevent damage caused by external forces. The tempered glass film is five times the standard of a PET film, without affecting the video effect of the screen, and can prevent a main screen from being crushed, scratched and scuffed. The tempered glass film also has enough strength to protect the display screen of the mobile phone against strong pressure. The mobile phone will withstand a great impact force by falling to the ground, and the screen will be crushed in case of excessive tension. The tempered glass film has a low resistance, and it will withstand the voltage when the voltage is transmitted by the mobile phone, therefore the voltage experienced by the main screen is greatly reduced. The existing tempered glass protective film is mainly planar type, which is mainly intended for a mobile phone with a flat screen.
    A type of screen phones with innovative curved surfaces, such as the Samsung Galaxy Edge series, have been launched. The design of the curved screen has become the trend, constituting the direction of the development of smartphone features. According to patent CN201620686193.5, filed by the applicant previously, structurally, a first adhesive layer is attached to the bottom surface of a curved surface tempered glass sheet, a reinforcing substrate layer is attached to the bottom surface of the first adhesive layer, a blue light-resistant layer is provided on the lower surface of the reinforcing substrate layer and has a two-layer structure comprising an OCA optical adhesive layer and a blue light-resistant PET substrate layer which are stacked up and down. The OCA optical adhesive layer is bonded to the reinforcing substrate layer, a second adhesive layer is provided on the lower surface of the blue light resistant layer, the second adhesive layer is the same as a colored reinforcing layer, terms of shape and dimensions, and a display area, corresponding to the mobile phone, in the middle of the second adhesive layer, is a hollow area. Such a structure primarily allows the entire tempered glass protective film to be attached to the screen of the mobile phone by means of the second layer of adhesive when attached to the screen of the mobile phone. Because the middle of the second adhesive layer is hollow, i.e. the middle zone, which is attached to the screen of the mobile phone, the product is hollow to cause air insulation and a weak penetration rate. In addition, the product is not fully adherent and completely fixed, so the touch control feel is not good when the touch screen is operated with the fingers.
