TWM416771U - A multifunctional reflective shielding film for LCD back light module - Google Patents

Abstract

A multifunctional reflecting and shielding film for a liquid crystal backlight module comprises a reflective layer (11), an adhesive layer (21), and a metal layer (31). The reflective layer (11) and the metal layer (31) are compounded integrally by the adhesive layer (21). The cross sections of the reflective layer (11), the adhesive layer (21), and the metal layer (31) are all concave shaped. The film can mount and fix various optical film materials in the backlight module, so as to omit a PC mounting frame, simplify the structure of the backlight module, reduce costs, and raise assembling efficiency.

Description

M4L6771. « V. New description: [New technical field] This creation relates to a multi-functional component for fixing frame, reflection, shielding and heat dissipation for LCD TV backlight module. [Prior Art] As the market demand continues to increase, mobile phones, game consoles, liquid crystal displays, LCD TVs, etc. • Electrical components are gradually becoming thinner, and as competition intensifies, the demand for display quality of electrical components is increasing. The higher the value, the more specific displays are required to be developed in terms of heat dissipation, thinness, and low cost. Chinese Patent No. 1825187A discloses a reflective sheet of a backlight module, the reflective sheet comprising a reflective layer and a conductive layer, the conductive layer being disposed on one side of the reflective layer and connecting the conductive layer to the ground of the backlight module. Thus, when the present invention is applied to a side-type backlight module or a direct-lit backlight module, grounding through the conductive layer prevents electromagnetic interference and electrostatic discharge from affecting the normal operation of the block member. θ ' Chinese Patent No. 201568896U discloses a structure of a reflective sheet structure and a backlight module of a backlight module. The reflective sheet structure of the backlight module comprises a plastic back sheet and a reflective sheet adhered to one side of the plastic back sheet. The plastic backing plate is selected from the group consisting of a polyethylene backing plate, a polyethylene terephthalate backing plate, a polypropylene backing plate, a polystyrene backing plate, and a polyvinyl chloride backing plate. The plates are all high molecular polymers, and their heat dissipation performance is poor. The above prior art has the disadvantages of the processing process _ not easy to clean, poor acid and alkali resistance, shielding, heat dissipation performance and many components. [New Content] The purpose of this creation is to overcome the shortcomings of the prior art described above, and to provide a multi-functional reflective shielding 液晶 for a liquid crystal backlight module integrating reflection, shielding, fixing frame and heat dissipation function. The multifunctional reflective shielding film for the liquid crystal backlight module of the present invention comprises a reflective layer, an adhesive layer and a metal layer, wherein the reflective layer and the metal layer are integrated into one through the adhesive layer, the reflective layer, the adhesive layer and the metal The cross section of the layer is "four" ^^ where the reflective layer provides backlight 3
