On existing market, the ultrathin backlight module has two kinds: a kind of is that light guide plate is 0.70～0.90mm, and the LGP of this thickness supports the use with 335LED; Also having a kind of is that light guide plate is 0.60～0.70mm, and the LGP of this thickness supports the use with 020LED.LGP includes etched surface and flour milling, and existing LGP flour milling and texture mask are burnishing surface, and glue frame dress LGP face is also burnishing surface.Because 3014LED is more competitively priced than 335LED and 020LED, select LED type and the supporting design of LGP directly to have influence on the cost of finished product, so select most favorable LED and the supporting design of LGP, this is cost-saved.

Summary of the invention

It is high that the purpose of this utility model is to solve the LED light source cost that has the backlight module existence now, 020LED or 335LED with high price join the technical problem that there is the wasting of resources in common LGP, and a kind of backlight module that adopts 3014LED and Wedge shape light conduction board that proposes.

The technical problem that proposes for solving the utility model, the technical scheme that adopts is: a kind of backlight module that adopts 3014LED and Wedge shape light conduction board, include LED and LGP, what described LED was located at LGP advances light side correspondence position, and it is characterized in that: described LED is 3014LED; Described LGP mainly is made of the light conducting plate body of integrative-structure and the wedge shape light conductor of being located at the light conducting plate body side; The broad side surface of described wedge shape light conductor is for entering the light side, the broad side surface that the light-emitting area of 3014LED connects, and the narrow side of wedge shape light conductor is connected with the light conducting plate body side.

Include as the further restriction to technical solutions of the utility model:

The light-emitting area equal height of the broad side surface of described wedge shape light conductor and 3014LED.

The broad side surface while of described wedge shape light conductor is perpendicular to flour milling and the etched surface of light conducting plate body, the front of wedge shape light conductor and the etched surface of light conducting plate body are in the same plane, and the reverse side of wedge shape light conductor is for connecting the inclined-plane of broad side surface and light conducting plate body flour milling.

Also include a glue frame, be provided with the draw-in groove that matches with LGP and 3014LED on the glue frame; In the relevant position that the wedge shape light conductor of described LGP and 3014LED are located at draw-in groove.

The beneficial effects of the utility model are: the utility model increases a wedge shape light conductor that connects LED on existing LGP, 3014LED and common ultra-thin light guide board can be used in conjunction with the production cost of reduction at a low price.The utility model structure, simple to operate, and easy to assembly, can guarantee the quality of finished product, save simultaneously the cost of material.

The specific embodiment

Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model, structure of the present utility model is further described.

With reference to shown in 7, the utility model comprises LED1, LGP 2 and glue frame 3; That LED1 adopts is 3014LED, and 3014LED be the paster LED of commonly using on the market at present, is of a size of 3.0*1.4*0.8mm, has high brightness, the brightness 2800-3600mcd of single core, and the relative 335LED of cost and 020LED lower.

Shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 7, LGP 2 described in the utility model is to extend a wedge shape light conductor 22 in advancing on the light side of traditional LGP, that is to say that the utility model LGP 2 is comprised of light conducting plate body 21 and wedge shape light conductor 22 two parts, these two parts are the integrative-structure of injection molded, light conducting plate body 21 that is to say the structure division identical with traditional LGP, includes the flour milling 211 and the etched surface 212 that are parallel to each other.
