Abstract

The invention provides a cooling film, a display device and a fabrication method of the display device. The cooling film comprises a heat conduction layer and a shielding layer, wherein the heat conduction layer is arranged on the shielding layer and comprises a metal layer and a first heat conduction layer, the metal layer is arranged on the first heat conduction layer, the first heat conductionlayer is arranged on the shielding layer, the positive projection of the shielding layer in a thickness direction covers the positive projection of the heat conduction layer in the thickness direction, and the area of the positive projection of the shielding layer in the thickness direction is larger than the area of the positive projection of the heat conduction layer in the thickness direction.By the cooling film, the display device comprising the cooling film cannot cause light leakage and is good in sealing performance and falling-resistant performance, and moreover, the fabrication process is simple.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a heat dissipation film, a display device and a manufacturing method thereof. Background technique [0002] At present, due to the limitation of the attachment process, the cover plate of the display device using the decorative film will have a certain margin at the edge, which will cause light leakage in the display device and affect the display. [0003] Therefore, the related technologies of the existing display devices still need to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a heat dissipation film that prevents light leakage of the display device, has good sealing performance, good anti-drop performance, or has a simple manufacturing process. [0005] In one aspect of the present invention, th...
