Description
Technical field
The utility model relates to display field, specifically relates to a kind of backlight module.
Background technology
Because liquid crystal display (Liquid Crystal Display, LCD) has the advantages such as slimming, lightweight, low power consumption, radiationless pollution, LCD product is more and more subject to liking of people.LCD is passive type electronic display unit, and need a backlight module to provide brightness, backlight module is divided into again straight-down negative and side entering type.Down straight aphototropism mode set is that illuminating source such as LED (Light Emitting Diode, light emitting diode) is arranged on the rear of liquid crystal panel, and direct forming surface light source is supplied to liquid crystal panel.And side entrance back module is side light source being arranged at liquid crystal panel, Fig. 1 is prior art side entrance back modular structure schematic diagram, side entrance back module comprises glue frame 11, optical diaphragm group 12, light guide plate 13, reflector plate 14, backboard 15 and LED light source 16, the light that LED light source 16 sends enters light guide plate 13 from light guide plate 13 incidence surface, from the injection of light guide plate 13 exiting surface after reflection and diffusion, then be supplied to liquid crystal panel via optical diaphragm group 12 with forming surface light source.
In side entrance back module, LED lamp bar (LED lamp bar and heat sink) and light guide plate are all fixed on backboard, need to leave suitable spacing and strike LED light source to avoid light guide plate because being heated and expand after moisture between light guide plate incident side and LED light source.But in large scale backlight module, the impact that light guide plate size is subject to more greatly temperature humidity is also just larger, if the too little meeting of the distance between light guide plate and LED light source strikes LED light source after causing light guide plate to expand, but spacing excessive LED light source light inlet efficiency difference causes backlight illumination not enough.
Utility model content
For solving the problem, the utility model provides a kind of backlight module combining light guide plate and use this combination light guide plate, by LED lamp bead being placed in the accommodating groove of combination light guide plate, solves LED light source and the too little easily impaired problem of light guide plate spacing.
The utility model provides a kind of backlight module combining light guide plate and use this combination light guide plate, combination light guide plate comprises a light-strip and a leading tabula rasa, wherein light-strip comprises the accommodating groove and the first draw-in groove that hold LED lamp bead, the first described draw-in groove by light-strip base plate upwards bending formed, leading tabula rasa comprises the second draw-in groove, and the first draw-in groove is by blocking mutually with the second draw-in groove and realizing the connection of light-strip and leading tabula rasa.The accommodating groove of described light-strip accommodation LED lamp bead is positioned at the incident side of light-strip.The micro-rib structure of the strip vertical with LED lamp bead light-emitting area is provided with in first draw-in groove of described light-strip.The micro-rib structure of the strip vertical with LED lamp bead light-emitting area is provided with in second draw-in groove of described leading tabula rasa.The section of described micro-rib structure is that triangle or zigzag are trapezoidal or square.
The utility model is by a kind of combination of design light guide plate, LED lamp bead is placed in the accommodating groove of combination light guide plate, gap between LED lamp bead and light guide plate ensures that LED lamp bead is not damaged less, can improve again the light inlet efficiency of LED lamp bead, thus improves the briliancy of backlight module.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
The utility model provides a kind of backlight module combining light guide plate and use this combination light guide plate, and combination light guide plate comprises light-strip 100 and a leading tabula rasa 110, and light-strip 100 is identical with leading tabula rasa 110 material, injection mo(u)lding.Fig. 2 is light-guiding strip structure schematic diagram in the utility model combination light guide plate, Fig. 3 is light-strip partial structurtes enlarged diagram in Fig. 2, light-strip 100 comprises the accommodating groove 101 and the first draw-in groove 102 that hold LED lamp bead, the accommodating groove 101 that light-strip 100 holds LED lamp bead is positioned at the incident side of light-strip 100, the first described draw-in groove 102 by light-strip 100 base plate upwards bending formed, be provided with the micro-rib structure 103 of the strip vertical with LED lamp bead light-emitting area in first draw-in groove 101 of light-strip 100, the section of micro-rib structure 103 is that triangle or zigzag are trapezoidal or square.Fig. 4 is LED lamp bar and light-strip assembling process schematic diagram, LED lamp bar 200 comprises several LED lamp bead 201, during installation, LED lamp bead 201 can be placed in the accommodating groove 101 of light-strip 100, and also leave certain distance between LED lamp bead 201 and light-strip 100, can ensure that LED lamp bead 201 is less with combination light guide plate gap like this, improve the light inlet efficiency of LED lamp bead 201, when can ensure that light guide plate expands again, do not strike LED lamp bead 201.Fig. 5 is that light-strip and leading tabula rasa assemble schematic diagram, Fig. 6 is Fig. 5 partial structurtes enlarged diagrams, leading tabula rasa 110 is provided with the second draw-in groove, the micro-rib structure of the strip vertical with LED lamp bead light-emitting area is provided with in second draw-in groove, the section of micro-rib structure is that triangle or zigzag are trapezoidal or square, and the first draw-in groove 102 of light-strip 100 is meshed by micro-rib structure with the second draw-in groove of leading tabula rasa 110.Also comprise elastomeric element in backlight module, elastomeric element is fixed on backboard, as combination light guide plate limited support, can absorb combination light guide plate and to expand the change in size caused, no longer need the light guide plate locating dowel on backboard, thus reduction module cost.
The utility model is by a kind of combination of design light guide plate, LED lamp bead is placed in the accommodating groove of combination light guide plate, gap between LED lamp bead and light guide plate ensures that LED lamp bead is not damaged less, can improve again the light inlet efficiency of LED lamp bead, thus improves the briliancy of backlight module.Ensureing under the certain condition of briliancy, a number of LED lamp bead can reduced or use less LED wafer (chip) under the constant condition of a LED lamp bead number, reducing LED lamp bar cost.
