Abstract
The present disclosure provides a heat dissipation module, a display device and an assembling method of the display device. In order to avoid the second windowing area from forming a sealed space during the defoaming treatment, an exhaust passage is formed between the second windowing area B and an edge of a heat dissipation film, and hot air formed in the second windowing area in a defoaming technology can be effectively released to the outside of the heat dissipation module through the exhaust passage, so that defects of the second windowing area can be effectively overcome, and increasing the attachment yield is facilitated.
Claims17
A heat dissipation module, comprising:
- a heat dissipation film, wherein the heat dissipation film comprises grid glue, foam and a metal film which are arranged in a stacked manner;
- a first release film arranged on one side, facing away from the foam, of the grid glue;
- a second release film arranged on one side, facing away from the foam, of the metal film, wherein the heat dissipation film and the second release film are provided with a first windowing area and a second windowing area which penetrate through a thickness direction, and an exhaust passage is arranged between the second windowing area and an edge of the heat dissipation film;
- a first protective film arranged on one side, facing away from the heat dissipation film, of the second release film, and covering the first windowing area;
- and
- a second protective film arranged on one side, facing away from the heat dissipation film, of the second release film, and covering the second windowing area and the exhaust passage, wherein the first protective film and the second protective film are independently arranged.
A display device, comprising:
- a display panel, wherein the display panel comprises a first light-transmitting area and a second light-transmitting area which are arranged on a display area;
- a heat dissipation film, wherein the heat dissipation film comprises:
- grid glue, foam and a metal film which are sequentially arranged on a back surface of the display panel in a stacked manner,
- a first windowing area penetrating through a thickness direction in the first light-transmitting area,
- a second windowing area penetrating through the thickness direction in the second light-transmitting area, and
- an exhaust passage between the second windowing area and an edge of the heat dissipation film;
- a first attachment module, wherein the first attachment module is arranged on the back surface of the display panel and fixed to the first light-transmitting area through the first windowing area;
- and
- a second attachment module, wherein the second attachment module is arranged on the back surface of the display panel and fixed to the second light-transmitting area through the second windowing area.
