Specific embodiment

The disclosure is described in detail below with reference to specific embodiment shown in the drawings.But these embodiments are simultaneously The disclosure is not limited, structure that those of ordinary skill in the art are made according to these embodiments, method or functionally Conversion is all contained in the protection domain of the disclosure.

It is only merely for the purpose of description specific embodiment in the term that the disclosure uses, and is not intended to be limiting the disclosure. " one kind " of singulative used in disclosure and the accompanying claims book, " described " and "the" are also intended to including majority Form, unless context clearly shows that other meanings.It is also understood that term "and/or" used herein refers to and wraps Containing one or more associated list items purposes, any or all may be combined.

Below in conjunction with the accompanying drawings, elaborate to some embodiments of the disclosure, it is in the case where there is no conflict, following Feature in embodiment and embodiment can be mutually combined.

As shown in Figure 1 to Figure 3, the backlight module 10 of the embodiment of the present disclosure includes：Luminescence component 1, light guide plate 2 and shading Glue-line 3.The luminescence component 1 includes the circuit board 11 for being arranged at 2 edge of light guide plate and the LED light source on circuit board 11 12, the LED light source 12 can be one, two or more, LED light source 12 is arranged at the side of light guide plate 2, LED light source 12 Light by light guide plate 2 edge directive light guide plate 2 center so that LED light source 12 to light guide plate 2 light it is completely guide-lighting Plate 2 absorbs, and the light source that LED light source 12 is sent can be become uniform area source by light guide plate 2, so as to improve display Brightness.The backlight module 10 can be adapted for mobile phone, tablet computer etc. and move equipment, be readily applicable to TV, personal meter The display devices such as calculation machine.

In the present embodiment, the quantity of the LED light source 12 is multiple, and multiple LED light sources 12 are equally spacedly arranged at circuit board On 11, the edge of light guide plate 2 is located at by multiple LED light sources 12, so as to so that area source increases brightness and bright on light guide plate 2 Degree is more uniform, and can also be by controlling quantity that LED light source 12 lights or brightness bright to adjust the area source of light guide plate 2 Degree.

As shown in Figures 1 to 4, the circuit board 11 of the disclosure is fitted in by shading glue film 3 on light guide plate 2, so that electric Road plate 11 is fixed on light guide plate 2.Preferably, the circuit board 11 of the disclosure is flexible PCB FPC (Flexible Printed Circuit), the thickness of backlight module 10 can be so reduced, meets Vehicles Collected from Market growth requirement, and uses the flexible circuit Plate can be conducive to the layout of circuit in backlight module 10.Wherein, correspond on light guide plate 2 at the position of LED light source 12 (i.e. 12 direct projection of LED light source is in the position on light guide plate 2), light guide section 21 is provided between light guide plate 2 and circuit board 11.It it is preferred that should Light guide section 21 can block the light-emitting zone of corresponding LED light source 12 as much as possible, so as to may mostly reduce generation The possibility of light leak.

Wherein, along the direction of the launch of LED light source 12, light guide section 21 has the height being gradually reduced.In the present embodiment, this is led 21 wedge shaped bulk of light portion, designing scheme with this configuration can be whole by the light in gap between light guide plate 2 and circuit board 11 Boot wizard tabula rasa 2, so as to which loss of light source will not be caused.

In an alternative embodiment, which is integrally formed with light guide plate 2 and sets, the light guide section 21 and light guide plate 2 Material identical, so can be in order to technique productions and manufacture, and the process that technique can be simplified, without individually carrying out leaded light The manufacture and assembling in portion 21.Certainly, in the other embodiment of the disclosure, it can also separate light guide section 21 and light guide plate 2 raw It produces and passing through optical cement etc. makes light guide section 21 be fixed on light guide plate 2.In addition, in the other embodiment of the disclosure, the leaded light Portion 21 can also lighttight structure, to block the direct light source of LED light source 12, the effect of light leak can also be played.

In the disclosure, between two neighboring light guide section 21, circuit board 11 is fixed on light guide plate 2 by shading glue film 3 On, it is fixed on light guide plate 2, but also the light of LED light source 12 can fully be passed such that circuit board 11 can not only be realized It imports in light guide plate 2, does not easily cause the loss of light source of LED light source 12, while decrease the possibility that light leak occurs.Wherein, The thickness of shading glue film 3 between adjacent light guide section 21 is not more than the maximum gauge of light guide section 21, and thickness herein refers to illustrate The direction that middle light guide plate 2 extends upward.

Further, it is smaller than phase of the light guide section 21 in two neighboring light guide section 21 between two neighboring light guide section 21 The upward size of other side (i.e. the width of light guide section 21).In the present embodiment, the width of light guide plate 2 is located at LED light source as much as possible In the range of 12 light emitting path, the light leak of LED light source 12 can be so reduced, the light that can fully project LED light source 12 It is conducted into light guide plate 2.

The reflectance coating 4 that the backlight module 10 of the disclosure further includes bottom plate 101 and is arranged on bottom plate 101, light guide plate 2 On reflectance coating 4, reflectance coating 4 and circuit board 11 are divided into the both sides of light guide plate 2.Specifically, which is located at light guide plate 2 lower section, circuit board 11 are located at the edge of 2 top of light guide plate, and do not influence shining for the light-emitting zone of the light guide plate 2.

Further, which further includes lower diffusion barrier 5, the prism being sequentially stacked above light guide plate 2 Piece 6, upper diffusion barrier 7 and framework 102.Wherein, acted on by the common convergence of upper diffusion barrier 7 and lower diffusion barrier 5, enhance light The intensity of line, and then the backlight intensity of backlight module 10 can be improved.The prismatic lens 6 can be by divergence of beam, it is ensured that the back of the body Luminous intensity and to the full extent reduction edge bright border happen.Framework 102 can be incited somebody to action anti-by coordinating with bottom plate 101 Penetrate film 4, light guide plate 2, lower diffusion barrier 5, prismatic lens 6, upper diffusion barrier 7 sequentially laminate packaging.

In the backlight module 10 of the disclosure, the light that LED light source 12 is sent is directly conducted in light guide plate 2, part light Line is conducted by light guide section 21 into light guide plate 2, and the point light source of each LED light source 12 is converted into area source by light guide plate 2, and is led to The cooperation for crossing reflectance coating 4 is projected upwards, and light is realized uniform by the cooperation of lower diffusion barrier 5, prismatic lens 6 and upper diffusion barrier 7 It exhales, enhances the intensity of light, and then the backlight intensity of backlight module 10 can be improved.In other embodiments, on this Bright enhancement film (not shown) is also provided on diffusion barrier 7, is enhanced further to be converged to light, so as to ensure the strong of backlight Degree.

It is improved by the structure to light guide plate in the backlight module of the disclosure, both realized between circuit board and light guide plate Connection, and solve the problems, such as the easy light leak of backlight module again, the light that can send LED light source is fully conducted into light guide plate Interior, the various components in backlight module realize uniform light and exhale, and enhance the intensity of light, and then can improve backlight The backlight intensity of module.
