Description
Technical field
The present invention relates to a kind of luminescence unit and have the backlight module of this luminescence unit, particularly relate to a kind of lower-cost luminescence unit and have the backlight module of this luminescence unit.
Background technology
Backlight module is in order to the planar light source as LCD, therefore, with uniformity relevant regulation is arranged all for the luminosity of backlight module, with display effect and the quality of guaranteeing LCD.
Existing backlight module mainly is with cathode fluorescent tube (Cold Cathode Fluorescent Lamps; CCFL) light that is sent is light source, but in order to respond the demand of world's environmental protection, and the demand that meets the LCD of continuous slimming; In recent years; Had more and more many backlight liquid crystal display module change to adopt color rendering is preferable, volume is little and not mercurous light emitting diode (Light Emitting Diode, the light that LED) is sent particularly are applied in mobile phone, notebook computer as light source; And the backlight liquid crystal display module, existing major part has changed with light emitting diode replacement cathode fluorescent tube.
But,, therefore,, certainly will need to increase the quantity of light emitting diode in order to reach original optical effect if replace the light source of existing side-light type cathode-luminescence fluorescent tube as backlight module with side-lighting type light-emitting diode because light emitting diode belongs to the point type light source.
In order to improve the shortcoming of light emitting diode point type light source; Relevant dealer develops the technology of announcing M344443 number " pliability reflector plate and applied light fixture thereof " novel patent like TaiWan, China; Its mainly improvement place be to be: this pliability reflector plate is at a polyethylene terephthalate (Polyethylene Terephthalate; PET) coating one optical reflecting layer on the plasticizing base material (for example: silver reflecting layer), with the light reflectance of the light emitting diode that improves the point type light source.
But; Because the undercapacity of the plasticizing base material of polyethylene terephthalate; When assembling, deform easily and influence the product yield; Therefore for this pliability reflector plate is applied on the backlight module, relevant dealer develops the light-emitting diode (LED) backlight module 1 of an one-sided light inlet as shown in Figure 1 then.
This light-emitting diode (LED) backlight module 1 comprises that a metal outer frame 11, is arranged at the LED source 13, that metal supporting frames 12, in this metal outer frame 11 is arranged on this metal supporting frames 12 and is arranged at the LGP 15 in this reflector 14 by being butted on this LED source 13 and by the reflector 14, of these metal supporting frames 12 folder systems, and a glue frame 16 around this metal outer frame 11.
Wherein, This LED source 13 has the circuit substrate 131 that is arranged on this metal supporting frames 12; And a plurality of light emitting diodes 132 that are arranged at intervals on this circuit substrate 131; And this reflector 14 has one and coats the optical reflecting layer 142 on this polyethylene terephthalate plasticizing base material 141 by the polyethylene terephthalate plasticizing base material 141, that is butted on this circuit substrate 131, and each light emitting diode 132 of a plurality of correspondences and be formed at the through hole 143 on this polyethylene terephthalate plasticizing base material 141.(because of only showing one of them light emitting diode 132 and a through hole 143 in the visual angle graph of a relation 1).Said light emitting diode 132 is that the back side by this polyethylene terephthalate plasticizing base material 141 is placed through in the corresponding through hole 143.
Utilize this metal supporting frames 12 to improve the intensity of this polyethylene terephthalate plasticizing base material 141; Effectively avoiding this polyethylene terephthalate plasticizing base material 141 when assembling, to deform influences whole yield, and utilizes the optical reflecting layer 142 that is coated with to improve the light reflectance of said light emitting diode 132.
But; These metal supporting frames 12 quality are hard, need the moulding of multiple working procedure ability, and the metal material price fluctuation are quite big; So this light-emitting diode (LED) backlight module 1 comparatively bothers on making and manufacturing cost is higher; In addition, because this metal supporting frames 12 is all metal material with this metal outer frame 11, cause the weight of this light-emitting diode (LED) backlight module 1 heavier.
For the weight of improving this light-emitting diode (LED) backlight module 1 heavier; And cost problem of higher; Relevant dealer develops technology as shown in Figure 2 then, its mainly improve be in: utilize to be covered on this glue frame 16 and to be positioned at this glue frame 16 and the reflection bar 17 of 15 of this LGPs, replace metal supporting frames 12 and reflector 14 among Fig. 1; Not only can alleviate overall weight whereby, reduce cost of material, can also improve light reflectance.But, owing to this reflection bar 17 need be covered on this glue frame 16 in addition, therefore, necessary many one procedures on making; In addition, because the surface 133 of the circuit substrate 131 of this LED source 13 is not an optical reflection face, therefore will cause the light reflectance of said light emitting diode 132 to reduce.
This shows that above-mentioned existing backlight module and luminescence unit thereof obviously still have inconvenience and defective, and demand urgently further improving in structure and use.In order to solve the problem of above-mentioned existence; Relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly; But do not see always that for a long time suitable design is developed completion, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of luminescence unit of new structure and have the backlight module of this luminescence unit, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
