Abstract
The utility model discloses a kind of LED backlight with novel FPC structure, comprise 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 2 support columns (5); The top of each locating dowel is provided with a locating dowel (6); FPC is attached to the sidepiece of light guide plate, and the spacing between 2 described locating dowels is equal with the spacing between 2 described locating holes; And 2 described locating dowels are inserted in 2 described locating holes; Described support column is cylinder, and LED is patch-type element, and the thickness of support column is equal with the thickness of LED.This LED backlight structure with novel FPC structure is ingenious, the backlight stability that energy effective guarantee is good.
Description
Technical field
The utility model relates to a kind of LED backlight with novel FPC structure.
Background technology
LED backlight generally provides light source by the LED on FPC, 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.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of LED backlight with novel FPC structure, and this LED backlight structure with novel FPC structure is ingenious, the backlight stability that energy effective guarantee is good.
The technical solution of utility model is as follows:
There is a LED backlight for novel FPC structure, comprise 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 2 support columns (5); The top of each locating dowel is provided with a locating dowel (6); FPC is attached to the sidepiece of light guide plate, and the spacing between 2 described locating dowels is equal with the spacing between 2 described locating holes; And 2 described locating dowels are inserted in 2 described locating holes; Described support column is cylinder, and LED is patch-type element, and the thickness of support column is equal with the thickness of LED.
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 2.1mm, and the diameter of described locating dowel is 2.0mm.
2 described locating holes lay respectively at two ends of the main body of FPC.
The back side of FPC and the back side of light guide plate are equipped with resistance photo-oil membrane (not marking in figure).Be specially and be coated with last layer ink formation oil lamella, easy to implement, resistance light effect is good, and the thickness increased is negligible.
Beneficial effect:
The LED backlight with novel FPC structure of the present utility model, locating hole on FPC realizes the location of FPC with cooperatively interacting in the locating dowel of light guide plate side plate, FPC can not be subjected to displacement relative to light guide plate, thus good stability, in addition, support column effectively for FPC provides support, can be avoided the existence because of LED paster to cause the height of FPC body to rise and fall, is conducive to the stable luminescence of LED so equally.
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).
In sum, this LED backlight with novel FPC structure has novel FPC detent mechanism, good reliability, the continual and steady work of energy effective guarantee LED backlight.
