Description

A kind of novel backlight module for improving illumination effect

Technical field

It the utility model is related to backlight module, more particularly to a kind of novel backlight module for improving illumination effect.

Background technology

Backlight module is one of key part and component of panel of LCD, and its function is well-off brightness with dividing The uniform light source of cloth, enables liquid crystal display normally to show image, and its illumination effect will directly influence LCD MODULE Visual effect.With the continuous development of lcd technology, the application neck of liquid crystal display particularly colour liquid crystal display device Domain is also constantly being widened, and is pulled by the market of liquid crystal display, backlight industry also develops rapidly therewith, in mobile phone industry application It is particularly extensive.But increase the endurance of mobile phone, client generally may require that standard configuration in the market in order to reduce power consumption The product of 5 cun of 12 LED lamp be changed into the product of 5.2 cun of 10 LED lamp, can so increase mobile phone screen, and can is equal to 5 cun Power consumption, but the relative difficulty that can increase light guide plate effect process, because the spacing mistake between 5.2 cun of 10 LED lamp and lamp Greatly, LED effective lighting angle is 120 degree, therefore backlight module can be presented that socket is bright, dark trend between lamp.Generally we can be more Change the structures of FPC double faced adhesive tapes to coordinate the treatment effect of light guide plate, the structure of FPC double faced adhesive tapes there are three kinds at present, is opening respectively Glue, back-shaped glue and chevron glue, but these three structures only to 5 cun and 5.5 cun of structure meet demand of processing, and for 5.2 Very little respective outer side edges three of the above double faced adhesive tape can be still presented, bad phenomenon.Such as Fig. 1 and Fig. 2, using opening glue, at socket The blast effect of the white oil of large area, LED light source, which injects visible area, can cause the serious hot spot of socket, and between lamp large area it is double The light blocking effect of face glue so that light source fails to import visible area, so as to cause shadow between lamp serious；Such as Fig. 3 and Fig. 4, use Chevron glue, white oil is covered by FPC double faced adhesive tapes at socket, and blast effect diminishes, and socket hot spot becomes slight, and between lamp double faced adhesive tape face Product is still very big, and shadow is still serious between lamp；Such as Fig. 5 and Fig. 6, using back-shaped glue, white oil is hidden by FPC double faced adhesive tapes at socket Lid, blast effect diminish, and hot spot becomes slight, and FPC double faced adhesive tapes area diminishes between lamp, and light blocking effect also reduces, and shadow lightens between lamp It is micro-.Three of the above situation, it is best using effect caused by back-shaped glue, but can still have slight hot spot and slight shadow, it is impossible to It is completely eliminated.

Therefore, the prior art is defective, it is necessary to improve.

Utility model content

The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of Novel back optical mode for improving illumination effect Group, shadow between socket hot spot and lamp can be eliminated.

The technical solution of the utility model is as follows：A kind of novel backlight module for improving illumination effect, including：Light guide plate, FPC located at the light guide plate incident side, some LEDs on the FPC and led described The glue frame that tabula rasa frames, the FPC are provided with two-sided on the light guide plate for the FPC to be affixed on Glue, the double faced adhesive tape are in tang shape, are used to house the LED if the LED on its corresponding described FPC is provided with Dry hole, the top in the hole of the double faced adhesive tape form projection.

Further, the spacing that the double faced adhesive tape is taken up an official post between two adjacent holes is equal.

Further, the projection is in isosceles trapezoid, and trapezoidal space is formed between adjacent two projection.

Further, the raised bottom is set close to the hole, length and the hole of the raised bottom Equal length, the upper bottom edge in the trapezoidal space is set close to the hole.

Further, the trapezoidal space silk-screen white oil.

Further, the LED quantity is 10.

Using such scheme, the utility model uses the double faced adhesive tape in tang shape, socket FPC double faced adhesive tapes widened, between lamp Double faced adhesive tape narrow, and by the trapezoidal gap silk-screen white oil between lamp, play a part of blast between socket light blocking, lamp, disappear completely Except shadow between socket hot spot and lamp, so as to improve overall illumination effect.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Fig. 7 to Fig. 9 is please referred to, the utility model provides a kind of novel backlight module for improving illumination effect, including： Light guide plate 10, the FPC 20 located at the incident side of light guide plate 10,10 LEDs on the FPC 20 Lamp 30 and the glue frame 40 for framing the light guide plate, the FPC 20, which is provided with, to be used for the FPC 20 The double faced adhesive tape being affixed on the light guide plate 10, the double faced adhesive tape are in tang shape, the LED on its corresponding described FPC 20 If 30 are provided with the dry hole 51 for being used for housing the LED 30, the top in the hole 51 of the double faced adhesive tape forms projection 52, described two-sided The spacing that glue is taken up an official post between two adjacent holes 51 is equal.

Described raised 52 be in isosceles trapezoid, and raised 52 bottom is set close to the hole 51, under described raised 52 The length on base and the equal length in the hole 51.Form trapezoidal space 53 between adjacent two projection, the trapezoidal space 53 it is upper Base is set close to the hole 51, and is beneficial to leaded light in the trapezoidal silk-screen white oil 54 of space 53, white oil, and light source can import visually Region, so as between blast lamp, and socket white oil is completely covered by by FPC double faced adhesive tapes, plays light blocking effect, thus socket hot spot It is invisible.

In summary, the utility model uses the double faced adhesive tape in tang shape, and socket FPC double faced adhesive tapes are widened, double between lamp Face glue narrows, and the trapezoidal gap between lamp is filled into white oil, plays a part of blast between socket light blocking, lamp, lamp is completely eliminated Shadow between mouth hot spot and lamp, so as to improve overall illumination effect.

Preferred embodiment of the present utility model is these are only, is not limited to the utility model, it is all in this practicality All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
