Embodiment Construction

[0042] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0043] see Figure 7-8 , the present invention provides a protective film, including a flexible film 10, a release film 20, and an adhesive 30 distributed between the flexible film 10 and the release film 20, wherein the release film 20 includes the same The main body 21 of the flexible film 10 is oppositely arranged and has the same size, and the tear-off part 22 is arranged on one side of the main body 21 and connected thereto;

[0044] The main body 21 is provided with cutting lines 212 distributed in the peripheral area. The cutting lines 212 divide the main body 21 into a central area 240 and an edge area 250. The central area 240 of the main body 21 includes a The strip part 213 connected to the part 22, a body 215, and a connecting par...

Abstract

The invention provides a protective film and a using method thereof. By designing the shape and position of a cutting line on a release film, an acting force centralizing position on a tearing part is made to be away from the cutting line. After the release film is cut and the edge of the release film is torn off, a strip-shaped part in fillet connection with the tearing part exists on a protective film body, so that when the tear part is lifted to tear the whole protective film, acting force applied to the tearing part is dispersed onto the whole protective film through the strip-shaped part, and then the protective film can be torn off from a protected object easily and the situation that the protective film can not be torn off or is broken caused by falling off of the tearing part is avoided.

Description

technical field [0001] The invention relates to a protective film, in particular to an easy-to-tear protective film and its application method. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, TVs, personal digital assistants due to their advantages of high image quality, power saving, thin body and wide application range. , digital cameras, notebook computers, desktop computers and other consumer electronics products have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. In the backlight module, due to the hollow design of the backplane, a protective film must be attached to prevent defects such as scratches in the subsequent process caused by the entry of ex...
