Abstract
The utility model discloses a kind of backlight source modules for LCD; including light guide plate and light emitting source; the light emitting source includes circuit board and several LED crystal particles; the LED crystal particle encapsulates for non-encapsulating; the LED crystal particle of the non-encapsulating encapsulation is fixedly installed on circuit board and is electrically connected with circuit board; several grooves corresponding with LED crystal particle are provided on the incidence surface of the light guide plate, the LED crystal particle of several non-encapsulating encapsulation is also arranged in several grooves on the incidence surface of light guide plate.The optical design when backlight source module can save encapsulation simplifies processing procedure, and can improving luminous efficiency.
Description
Technical field
The utility model is related to a kind of backlight source modules, more particularly to a kind of backlight source module for LCD.
Background technology
Polaroid is commonly applied to make liquid crystal display panel, before assembly, needs first to be detected polaroid, confirms polaroid
Quality, polaroid is applied to so as to subsequently to make the devices such as liquid crystal display panel.In the detection, fiber must detect in film
Defect, and existing detection device cannot be distinguished to scrape outside film and injure fiber in film.
Utility model content
In view of the above shortcomings of the prior art, technical problem to be solved in the utility model is：It provides a kind of for LCD
Backlight source module, including light guide plate and light emitting source, the light emitting source includes circuit board and several LED crystal particles, described
LED crystal particle is the encapsulation of non-encapsulating, the LED crystal particle of non-encapsulating encapsulation be fixedly installed on circuit board and with
Circuit board is electrically connected, and several grooves corresponding with LED crystal particle are provided on the incidence surface of the light guide plate, should
The LED crystal particle of several non-encapsulating encapsulation is also arranged in several grooves on the incidence surface of light guide plate.
Wherein, the light guide plate is in tabular.
Wherein, several grooves are small shrinkage pool.
Wherein, several grooves are small concave surface.
Wherein, the circuit board is printed circuit board.
Wherein, the circuit board is flexible PCB.
In the utility model, the LED crystal particle requires no the group that backlight source module can be completed in encapsulating encapsulation
Dress, optical design when can not only save encapsulation simplify processing procedure, and may make between LED crystal particle and light guide plate without knot
Light loss caused by closing leakage loss or penetrating packing colloid due to light, has the function of improving luminous efficiency.Simultaneously as not by
The LED crystal particle of encapsulating encapsulation is directly arranged on light guide plate, may make that full wafer light guide plate almost all is luminous zone
Domain equally has the function of improving luminous efficiency.
Description of the drawings
Fig. 1 and Fig. 2 is a kind of structure of the better embodiment of backlight source module for LCD described in the utility model
Schematic diagram.
Fig. 3 is the combination diagram after light guide plate is combined with light emitting source in Fig. 2 in Fig. 1.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It refers to shown in Fig. 1 and Fig. 2, a kind of preferable implementation of backlight source module for LCD described in the utility model
Mode includes light guide plate 1 and light emitting source 2.The light guide plate 1 is made of materials such as PC or PMMA, and is in tabular.It is described to shine
Source 2 includes circuit board 20 and several LED crystal particles 22, and the LED crystal particle 22 encapsulates for non-encapsulating, this is not filled
The LED crystal particle 22 of glue encapsulation is fixedly installed on circuit board 20 and is electrically connected with circuit board 20.The light guide plate 1
Incidence surface on be provided with several grooves 10 corresponding with LED crystal particle 22, which shines two
Pole pipe crystal grain 22 is also arranged at (as shown in Figure 3) in several grooves 10 on the incidence surface of light guide plate 1.The light emitting diode
Crystal grain 22 linearly has certain interval between arrangement and each two LED crystal particle 22.
In present embodiment, several grooves 10 can be small shrinkage pool, also can be small concave surface.The circuit board 20 can be print
Printed circuit board also can be flexible PCB.
In the utility model, the LED crystal particle 22 requires no encapsulating encapsulation and backlight source module can be completed
Assembling, optical design when can not only save encapsulation simplify processing procedure, and may make LED crystal particle 22 and light guide plate 1 it
Between without combining leakage loss or due to light penetrating packing colloid caused by light loss, have the function of improving luminous efficiency.
Simultaneously as the LED crystal particle 22 not encapsulated by encapsulating is directly arranged on light guide plate 1, may make whole
1 almost all of piece light guide plate is light-emitting zone, equally has the function of improving luminous efficiency.
It these are only the embodiment of the utility model, it does not limit the scope of the patent of the present invention, every profit
The equivalent structure or equivalent flow shift made by the utility model specification and accompanying drawing content, is applied directly or indirectly in it
His relevant technical field, is equally included in the patent within the scope of the utility model.
