Description
Technical field
The utility model relates to a kind of New type LCD backlight source optical component.
Background technology
LED backlight optical module is generally by FPC(flexible printed circuit board) on LED light source is provided, because FPC is attached to the side plate of light guide plate, lack location and fixed mechanism, thus FPC easily produces relative dislocation with light guide plate, thus affect backlight effect and easily cause FPC to damage, therefore, be necessary to design a kind of novel LED backlight optical module.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of New type LCD backlight source optical component, and this New type LCD backlight source optical component structure is ingenious, the backlight stability that energy effective guarantee is good.
The technical solution of utility model is as follows:
A kind of New type LCD backlight source optical component, comprises FPC(1) and light guide plate (2), FPC is provided with multiple LED (3) and the pad (7) for introducing power supply; FPC is also provided with 2 locating holes (4); The sidepiece of light guide plate is provided with many arc grooves (5) of 2 locating dowels (6) and lateral arrangement; FPC is attached to the sidepiece of light guide plate, and the position of 3 described locating dowels is corresponding with the position of 2 described locating holes, and 2 described locating dowels are inserted in 2 described locating holes; LED is patch-type element, and the cross section of arc groove is circular arc; The quantity of arc groove is equal with the quantity of LED, and multiple LED correspondence is inlaid in many arc grooves.
Described pad is 4; Wherein 2 pads are positive terminal pad, and other 2 pads are ground pad.
The diameter of described locating hole is 3.1mm, and the diameter of described locating dowel is 3mm, and the thickness of locating dowel is 1mm.
2 described locating holes lay respectively at two ends of the main body of FPC.
Described LED and arc groove are 3.
The back side of FPC and the back side of light guide plate are equipped with resistance photo-oil membrane.
LED is high bright light, and as adopted 0603 side Luminous paster LED of Dongguan City Lan Jin Photoelectric Co., Ltd., brightness reaches 560-900mcd.
Beneficial effect:
New type LCD backlight source optical component of the present utility model, 3 locating holes on FPC realize the location of FPC with cooperatively interacting in 3 locating dowels of light guide plate side plate, FPC can not be subjected to displacement relative to light guide plate, thus good stability, in addition, arc groove coordinates with the LED of protrusion, can effectively for FPC provides support, avoid the existence because of LED paster to cause the height of FPC body to rise and fall, be conducive to the stable luminescence of LED so equally.
And, because arc groove has the exiting surface of arc, thus can the light that sends of effective guarantee light guide plate more even, realize better backlight effect.
And, adopt the pad design of redundancy, power supply is introduced more reliable, even if a solder joint produces rosin joint or other faults, also backlight can not be affected, in addition, the pad design of redundancy adds the width of golden finger, makes the switching performance of FPC be enhanced (being namely not easy to be pulled off at pad place).
The oil lamella that one deck ink that resistance photo-oil membrane is specially coating is formed, easy to implement, resistance light effect is good, thus the efficiency of backlight is high.And the thickness increased is negligible.
In sum, this New type LCD backlight source optical component has novel FPC detent mechanism, good reliability, and the continual and steady work of energy effective guarantee LCD backlight source optical component, backlight efficiency is high.
