Embodiment
The present invention is disclosed to be a kind of light source module of LCD, adapts to the LCD of different panels size with the light source design with an adjustable.In order to make narration of the present invention more detailed and complete, series is lifted following preferred embodiment with explanation the present invention.Please refer to following description and cooperate following graphic.
Light source module disclosed in this invention comprises a plurality of LED encapsulation units and a plurality of linkage unit.Above-mentioned LED encapsulation unit all has a junction respectively in both sides.And above-mentioned linkage unit also all has a junction respectively in both sides, and described linkage unit can be connected in series by connecting portion mutually with described LED encapsulation unit.Can be between each connecting portion by disposing copper foil circuit or electrical contact to reach electrically connect.In a preferred embodiment, the connecting portion of LED encapsulation unit of the present invention and linkage unit both sides can a public plug and female plug seat pattern enforcement.Please refer to Fig. 2 A～Fig. 2 B, is to show that the connecting portion of a LED encapsulation unit 241 and a linkage unit 242 is the synoptic diagram of public plug and female plug seat pattern.Wherein each LED encapsulation unit 241 and linkage unit 242 both sides have connecting portion 241a, 241b, 242a, 242b respectively.Wherein this connecting portion 241a, 242a are the form of female plug seat, this connecting portion 241b, 242b are the form of public plug, and the electrical binding of in the configuration of this public plug and female plug seat, need arranging in pairs or groups within it, the mode of binding can be configuration copper foil circuit AA (shown in Fig. 2 A) or configuration electrical contact BB (shown in Fig. 2 B).
Light source module disclosed in this invention, can by the assembled arrangement that changes linkage unit and LED encapsulation unit constitute and quantity with in the LCD that is applied to different size or different Luminance Distribution demands.
Please refer to Fig. 3, be applied to a preferred embodiment structural representation sketch of LCD for light source module disclosed in this invention.LCD 2 among Fig. 3 comprises a display panel 21 and a backlight module 22.Backlight module 22 comprises a light guide plate 23, a sidelight source module 24, a framework 25 and a printed circuit board (PCB) 26.Wherein sidelight source module 24 is arranged on the framework 25 of light guide plate 23 1 sides.Sidelight source module 24 also comprises a plurality of LED encapsulation units 241 and a plurality of linkage unit 242.Each LED encapsulation unit 241 and linkage unit 242 both sides have connecting portion 241a, 241b respectively, 242a, 242b (seeing also Fig. 2 A and Fig. 2 B).Comprise the LED lamp in the LED encapsulation unit 241 and link electrical structure (can be copper foil circuit or metallic contact), and each linkage unit 242 is in order to as 241 electrically connect between the LED encapsulation unit, and see through other connecting portion and be connected in series.
