Embodiment 1
[0021] Reference figure 2 , Which shows a schematic structural diagram of a reflective film according to the first embodiment of the present invention.
[0022] The reflective film 1 is applied to a backlight module, the light source of the backlight module has a dark area formed on the reflective film 1, and the reflective film is coated with a thermoluminescent material 2 at the dark area.
[0023] After a product design is determined, the dark area is also determined, that is, the area of the generated dark area will not change, so the thickness of the thermoluminescent material 2 coating can be adjusted according to the dark area. Preferably, The coating thickness of the thermoluminescent material 2 is 20um-50um, which is not specifically limited in the present invention.
[0024] A thermoluminescent material solution is coated on the dark area of the reflective film, and after a series of treatments, the thermoluminescent material solution is dried to form a thermoluminesce...
Embodiment 2
[0028] Reference image 3 , Which shows a schematic structural diagram of a reflective film according to the second embodiment of the present invention.
[0029] The reflective film 1 is applied to a backlight module, the light source of the backlight module has a dark area formed on the reflective film 1, and the reflective film is coated with a thermoluminescent material 2 on the front surface of the dark area. , The backside of the dark area is coated with an endothermic and heat accumulating material 3.
[0030] Because after a product design is determined, the area of the dark area will not change. The thickness of the thermoluminescent material 2 and the endothermic heat gathering material 3 can be adjusted according to the dark area. Preferably, the The coating thickness of the thermoluminescent material 2 and the endothermic heat gathering material 3 is 20um-50um, which is not specifically limited in this application.
[0031] Apply a mixture of thermoluminescent material ...
Embodiment 3
[0042] The invention also discloses a backlight module, including the reflective film described in the first to second embodiments.
[0043] The backlight module has all the advantages of the reflective film in the first to second embodiments described above, and will not be repeated here.
