Background technology
At present, backlight module is widely used in the various display unit such as notebook, panel computer, TV, mobile phone, outdoor indoor advertisement machine, and display panels itself can not be luminous, needs backlight module to provide backlight to show for it.General backlight module, as the brightness provided for the backlight module of notebook computer, though enough supply user in indoor environment work, in outdoor environment, surround lighting then causes the deficiency of display unit brightness.Be applicable to open air for improving the producible brightness of display unit to make display unit, one of method is the light source density increasing backlight module; But the heat energy increasing light source density generation but may cause light source module temperature to raise to be affected the lamp pearl life-span or makes blooming piece be subject to warpage, or affects the rotation of liquid crystal molecule.The heat sink material that existing backlight module uses generally comprises the heat-radiation coating bed of material, metal base, heat-conducting glue adhensive layer, because the thermal conductivity factor of the heat-radiation coating bed of material is: 600 ~ 1500w/ (m.k), the thermal conductivity factor of metal base is: 200 ~ 300w/ (m.k), the thermal conductivity factor of heat-conducting glue adhensive layer is: 1.0 ~ 2.8w/ (m.k), due to the restriction of the thermal conductivity factor of heat-conducting glue adhensive layer own, the thermal conductivity factor of this heat sink material entirety is caused not reach the cooling requirements of modern highly integrated electronic device; Metal base uses the simple metal of sheet material, and manufacturing cost is high.
Utility model content
The utility model provides the backlight module conducting strip that a kind of structure is simple, easy to install, increase work efficiency for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
This backlight module conducting strip comprises: thermal dispersant coatings, metal-based layer, heat absorbing coating; Heat absorbing coating inside is provided with the network of hollow, heat absorbing coating is equipped with metal-based layer, metal-based layer is equipped with thermal dispersant coatings.
The utility model can also adopt following technical measures:
Described thermal dispersant coatings adopts graphite radiating coating, and graphite radiating coating proportioning is the acrylic acid of the graphite powder of mass ratio 40%-60%, the Graphene of 0%-5%, ALN, 0%-5% of 10%-20%.
Described metal-based layer adopts Copper Foil metal-based layer.
Described metal-based layer adopts aluminum foil metal basic unit.
Described heat absorbing coating adopts ceramic powders heat absorbing coating.Ceramic powders heat absorbing coating proportioning is the Y2O3 of the high-purity SIC ceramic powders of 0.3um of mass ratio 90%-95%, Al2O3,0%-5% of 0%-5%; Ceramic powders heat absorbing coating has the network of hollow, and the aperture of ceramic powders heat absorbing coating between 8 ~ 60ppi, can be beneficial to being uniformly distributed of air stream.
The thermal source of heat absorbing coating directly and in backlight module is close to, make heat absorbing coating can fast endothermic at short notice, and then be transmitted on thermal dispersant coatings by metal-based layer, thermal dispersant coatings is again by the mode with air exchange heat and radiation, heat is distributed, owing to absorbing heat fast by heat absorbing coating, then conducted by metal-based layer and thermal dispersant coatings.
The advantage that the utility model has and good effect are: this backlight module conducting strip can absorb heat fast due to heat absorbing coating, then conducted by metal-based layer and thermal dispersant coatings, than the mode of traditional use heat-conducting glue adhensive layer, the speed of heat radiation improves 2 ~ 3 times, the problem of heat radiation can better be solved, extend the life-span of lamp pearl and even whole module.
