Referring to Fig. 2, backlight module 10 includes backboard 11, plastic frame 12, reflector plate 13, light guide plate 14 and optical diaphragm 15.Plastic frame 12 is set on backboard 11, and backboard 11 and plastic frame 12 are enclosed receiving portion.Reflector plate 13, light guide plate 14 and light Diaphragm 15 is learned to be set in turn in receiving portion.
Referring to Fig. 3, the generally rectangular shaped frame-shaped of plastic frame 12, plastic frame 12 includes 121 He of first side being oppositely arranged Second side 122, and the third side 123 being oppositely arranged and four side 124, first side 121, third side 123, Dual side-edge 122 and four side 124 are successively end to end, to form rectangular box-like structure.Backlight module 10 further includes light Source component 18.In one embodiment, backlight module 10 is side-light type, and light source assembly 18 is set to third side 123 and is located at leaded light One end of plate 14.The four side 124 and backboard 11 of plastic frame 12 are formed with accommodating space 125, and the other end of light guide plate 14 holds It is contained in accommodating space 125.
The scattering direction for the light that light guide plate 14 is used to that light source assembly 18 to be guided to issue, to improve the bright of display device 100 Degree, and ensure the brightness uniformity of display device 100.Reflector plate 13 is set to the bottom of light guide plate 14, can will be from backlight mould The light that 12 bottoms of group leak out is reflected back light guide plate 14, prevents light exposed, to improve the service efficiency of light.Optical diaphragm 15 wraps Include diffusion sheet and prismatic lens etc..Light source assembly 18 includes multiple light emitting diodes (LED) and reflector, what light source assembly 18 issued Light is white light.Each light emitting diode issues white light, is also possible to multiple and different color LED and constitutes overall structure, the overall structure Issue white light.Reflector is arranged around LED, for reflecting the light of LED sending.
Referring to Fig. 4, backlight module 10 further includes several bolsters 16, bolster 16 is set to first side 121 and leads Between tabula rasa 14 and between second side 122 and light guide plate 14.
In assembly, first side 121, the second side 122 of plastic frame 12 inevitably exist with light guide plate 14 Gap, backlight module 10 occur accident fall or transportational process in, light guide plate 14 and plastic frame 12 can occur relative movement or even It hits, so that chipping occurs in light guide plate 14.
To solve the above problems, the present invention adds bolster 16 between light guide plate 14 and plastic frame 12, specifically, buffering Part 16 is set between light guide plate 14 and first side 121 and between light guide plate 14 and second side 122.The bolster 16 Setting, can effectively limit the relative position of light guide plate 14 and plastic frame 12, when avoiding backlight module 10 that accident occurs falling, lead Tabula rasa 14 and plastic frame 12 occur to hit and backlight module 10 is caused to show exception.
In some embodiments, first side 121 and second side 122 offer several mounting groove 121a/122a, delay Stamping 16 includes that the sticking part 161 being connected and auxiliary section 162, auxiliary section 162 are contained in mounting groove 121a/122a, is bonded Portion 161 is abutted against with light guide plate 14.It is cooperated by auxiliary section 162 and mounting groove 121a/122a, can be avoided bolster 16 It is being moved along first side 121 or 122 extending direction of second side relative to plastic frame 12.And increase bolster 16 with The contact area of plastic frame 12 facilitates the assembly of bolster 16, such as bolster 16 can be adhered to plastic frame using glue 12。
In addition, bolster 16 can be symmetrically disposed on and be led to improve the assembly reliability of light guide plate 14 and plastic frame 12 The two sides of tabula rasa 14, i.e., multiple bolsters 16 are symmetrical about the center line of light guide plate 14.By by the mounting groove of first side 121 The 121a/122a and mounting groove 121a/122a of second side 122 is symmetrical arranged, and is facilitated the installation of bolster 16 to position, is effectively mentioned High assembly efficiency.
Specifically, mounting groove 121a/122a can be swallow-tail form, rectangular or trapezoidal.
The spacing of light guide plate 14 and first side 121 or second side 122 is a, and the width of sticking part 161 is b, and a is less than Or it is equal to b.That is, sticking part 161 and light guide plate 14 and plastic frame 12 are interference fitted, be conducive to improve light guide plate 14 and modeling The assembly reliability of glue frame 12.
Further, the material of bolster 16 includes rubber, can occur one using bolster 16 made of rubber material The elastic deformation of tentering degree avoids light guide plate 14 from being damaged to absorb impact force.It should be understood that can be with one by mold It is body formed or stamp out aforementioned bolster 16.
In other embodiments, the material of bolster 16 can also be the two-sided foam rubber with bonding agent.
Referring to Fig. 2, backlight module 10 further includes rubber parts 17, and rubber parts 17 is located in light guide plate 14 and plastic frame Between 12.In 10 assembling process of backlight module, using the four side 124 of plastic frame 12 as contraposition side.Due to light guide plate 14 It is hard material with plastic frame 12, light guide plate 14 and 12 mutual extrusion of plastic frame are easy to make 14 fragmentation of light guide plate when assembly.It is logical Setting rubber parts 17 is crossed, light guide plate 14 and plastic frame 12 in assembling process is avoided mutually to hit and rupture light guide plate 14.And The rubber parts 17 can play position-limiting action to light guide plate 14 in thickness direction, and light guide plate 14 is avoided to shake in plastic frame 12 It is dynamic.It is fixed guide-lighting compared to using double-sided adhesive since the bonding effect of double-sided adhesive may fail in the long-term use The relative position of plate 14 and plastic frame 12, the present invention fix the relative position of plastic frame 12 and light guide plate 14 using rubber parts 17, High reliablity is conducive to the yield for promoting backlight module 10, and assembles easier.
Specifically, rubber parts 17 includes the first side wall 171 that is oppositely arranged and second sidewall 172, the first side wall 171 and the The spacing of two side walls 172 is less than or equal to the thickness of light guide plate 14, to ensure that rubber parts 17 is sufficiently bonded with light guide plate 14.
It should be noted that the embodiment of the present invention is not limited to sidelight type backlight module, backlight type backlight module can also be.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
