Abstract

The invention discloses a triply-connected multilayer protective film for a mobile-phone screen and a using method thereof. The triply-connected multilayer protective film comprises five layers of films which are mutually conglutinated, wherein the five layers of films are sequentially an outer-layer protective film, a shape-positioning film, a screen-protecting film, a parting film and a PE (Poly Ethylene) film, wherein the outer-layer protective film covers outside the shape-positioning film and completely covers the shape-positioning film; cutting lines are arranged on the shape-positioning film, and three shape-positioning areas which are arranged in parallel and are adapted to the shape of a mobile phone are formed by the cutting lines; cutting lines are arranged on the screen-protecting film, and three window areas which are arranged in parallel and are adapted to the mobile phone screen are formed by the cutting lines; and the three shape-positioning areas on the shape-positioning film respectively cover the three window areas on the screen-protecting film. Through the mode, the triply-connected multilayer protective film can be rapidly positioned, so that the screen-protecting film can be rapidly pasted onto the mobile phone screen, and films can be once pasted onto three mobile phones, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of screen protectors, in particular to a three-piece multilayer protective film used for a mobile phone screen and a method for using the same. Background technique [0002] Mobile phones and laptops are commonly used in our daily life, and their screens directly affect their use effects. For this reason, in the production process, in order to prevent the LCD screen and mobile phone screen from accidentally being scratched by friction, contact and other factors during the process of manufacturing and assembling the whole set of products, or being stained with foreign objects, and the screen is dirty, the LCD screen and The mobile phone screen needs to be protected with a protective film during the production process. Because the conventional mobile phone screen protective film does not have shape positioning, workers need to match the protective film with the mobile phone screen, then tear off the release film of the...
