Embodiment Construction
[0033] Embodiments of the present invention are described in detail below. The embodiments described below are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0034] In the related art, the display panel includes a heat dissipation film 10, a display panel 20, a cover plate 30, and a middle frame 40 (refer to figure 1 , the left picture is a schematic diagram of the planar section structure of the display device, and the right picture is a schematic diagram of the longitudinal section structure of the display device), most of which use 3D cover (cover), in order to overcome the technical difficulties of 3D cover ink printing, more use of pasting decoration The cover plate 30 of the display device is fabricated by means of Deco Film. However, due to the limitation of the attachment process, the cover plate 30 with a decorative film will have a certain whiteness 1000 on the edge of the cover plate 30. After th...

The invention provides a heat dissipation film, a display device and a manufacturing method thereof. The heat dissipation film includes: a heat conduction layer and a light shielding layer, the heat conduction layer is arranged on the light shield layer; the heat conduction layer includes a metal layer and a first heat conduction layer, and the metal layer is arranged between the first heat conduction layer Above, the first heat conduction layer is arranged on the light shielding layer; wherein, the orthographic projection of the light shielding layer in the thickness direction covers the orthographic projection of the heat conduction layer in the thickness direction, and the light shielding layer The area of the orthographic projection in the thickness direction is larger than the area of the orthographic projection of the heat conducting layer in the thickness direction. The heat dissipation film can prevent light leakage from the display device including the heat dissipation film, has good sealing performance, good anti-drop performance, and simple manufacturing process.
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...
