Among one of the present invention embodiment, the reflecting layer is transparence, and the refractive index in reflecting layer is less than the refractive index of LGP.
Among one of the present invention embodiment, LGP is a flexible circuit base board, and this substrate has a plurality of optical microstructures, lays respectively at the face in addition of its incidence surface, the relative exiting surface of substrate, or is positioned at the face in addition of its incidence surface and the relative exiting surface of substrate simultaneously.
Among one of the present invention embodiment, this kind electronic installation is a mouse, keyboard, mobile phone, video camera, camera, game machine, wrist-watch, music player, electronic mail transceiver, map navigator or digital frame.
In another aspect of the present invention, the method for making of this kind backlight module, comprising step is: a LGP is provided, wherein LGP has an exiting surface, afterwards, and according to one first pattern, one reflecting layer is formed on the exiting surface of LGP, afterwards, according to one second pattern, silver medal slurry circuit layer is formed on first pattern.
So, by the reflecting layer between silver slurry circuit layer and LGP, when the light in the LGP is starched the zone of circuit layer towards bright dipping mask silver, after the layer that can be reflected reflects back into LGP, do not have a regional bright dipping of reflecting layer or silver slurry circuit layer by exiting surface again, so, just can increase and more have more the ray machine meeting, the utilization rate of luminance and light source is provided.
The invention provides a kind of backlight module, its method for making and adopt the electronic installation of this backlight module, is before making silver slurry circuit on the LGP, at silver slurry circuit the correspondence position that is provided with is formed a reflecting layer in advance.So, before light is directed to silver slurry circuit, in layer reflected back LGP that promptly be reflected, to improve light reflectance, reduce light by the silver slurry chance that circuit absorbed, and then slow down the problem that LGP produces unexpected colour cast, improve the utilization rate of light source thus and go out light quality.
See also Fig. 1 to shown in Figure 3, this kind backlight module 100 comprises a LGP 200, a light source 300, a reflecting layer 400 and silver medal slurry circuit layer 500.LGP 200 has an incidence surface 210 and an exiting surface 220.This light source 300, for example be CCFL (Cold Cathode FluorescentLamp, CCFL) or light emitting diode (light-emitting diode LED), roughly is positioned at the incidence surface 210 of LGP 200, and luminous towards incidence surface 210.Reflecting layer 400 is the surfaces of being presented in exiting surface 220 with one first pattern.Silver slurry circuit layer 500 is to be presented on first pattern in reflecting layer 400 with one second pattern, and this second pattern is a circuit distribution map.The circuit distribution map can externally electrically connect respectively, and carries out the running of specific function.
So, after the light of light source 300 entered LGP 200, light can not had a zone 222 of reflecting layer 400 or silver slurry circuit layer 500 by exiting surface 220 and carried out bright dipping; Perhaps, because reflecting layer 400 is between silver slurry circuit layer 500 and LGP 200, when the light of light source 300 marches to reflecting layer 400 in LGP 200, light can be reflected in the layer 400 reflected back LGP 200, does not have regional 222 bright dippings of reflecting layer 400 or silver slurry circuit layer 500 by exiting surface 220 again.
Thus, the light of advancing towards the direction of silver slurry circuit layer 500 in the LGP 200 just can not starched circuit layer 500 by silver and absorb, and then provides more rays to exiting surface 220 with tossing about in bed, higher luminosity to be provided and to promote the utilization rate of light source 300.
