Embodiment Construction

[0050] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0051] Please refer to figure 1 , which is a schematic diagram of the appearance structure of the protective film according to an embodiment of the present invention. Such as figure 1 As shown, the protective film 1 described in this embodiment has a distribution direction X, an extension direction Z and a thickness direction Y. Wherein the extension direction Z is perpendicular to the distribution direction X, and the thickness direction Y is perpendicular to the distribution direction X and at the same time perpendicular to the thickness direction Y. The protection film 1 described in this embodiment further includes a first surface 11 and a second surface 12 . The first surface 11 includes a plurality of first convex portions 111 extending along the extending direction Z and a plurality of first concave portions 112 exte...

Abstract

A protective film has distribution direction, the extending direction perpendicular to the direction of distribution, and thickness direction perpendicular to the distribution direction and perpendicular to the extending direction. The protective film comprises a first surface and a second surface. The first surface includes a plurality of first convex surface portion extending along the extending direction and a plurality of the first concave portion extending along the extending direction. These first convex surface portion are staggered with the first concave surface portion along the direction of the distribution. The second surface comprises a plurality of second convex surface portion extending along the extending direction and a plurality of second concave portion extending along the extending direction. These second concave portion and these second convex portion are staggered along the direction of distribution. These first convex surface portion corresponds to the second concave portion in the thickness direction. The first concave portion corresponds to the second convex surface portion in the thickness direction.

Description

technical field [0001] The invention relates to a protective film, and in particular to a protective film for protecting the display surface of a display panel. Background technique [0002] The liquid crystal display module is an important component of the optical display structure. During the process of production, assembly and handling, the components should be avoided from being polluted or damaged as much as possible, so as to stabilize the product quality. After the liquid crystal display module is assembled, a protective film is attached to the display surface of the liquid crystal display module to protect the display surface of the liquid crystal display module from dust pollution or mechanical scratches during transportation. [0003] The protective films usually used to protect the display surface of the liquid crystal display module can be classified into adhesive protective films and non-adhesive protective films. The adhesive protective film is attached to the...
