Technical field
The utility model is improved at glue frame in the backlight module, aims to provide a kind of side leakage optical phenomenon that improves, and guarantees the glue frame elastic construction of display effect.
Background technology
The flat-panel screens industry was fast-developing in recent years, and in order more to promote display performance, industry all is devoted to the improvement and the design of each modular construction, and the backlight module in the LCD, especially towards providing high direction even, higher source luminance to improve.
Because liquid crystal itself can be not luminous, must add backlight (for example fluorescent tube or light emitting diode) at the display panels rear, after light source projects gone out, earlier through a Polarizer and then through liquid crystal, this moment, LCD changed the arrangement mode of liquid crystal molecule with regard to the variation that utilizes voltage, and and then changed the light angle that penetrates liquid crystal.Therefore, just can control the light intensity of last appearance as long as change the magnitude of voltage that can stimulate liquid crystal to change, and then the color combination of the different depths can on liquid crystal panel, occur.
According to the difference of light source position, backlight module generally can be divided into two kinds of side-light type (Edge Lighting) and straight-down negatives (Bottom Lighting).Side light type back light module generally is usually used in middle-size and small-size display, as mobile computer screen, PDA and mobile phone screen etc.; And wherein, LGP is the key part and component of side light type back light module, its main function be with light by the edge guiding direction of visual lines, the light that concentrates on the edge by LGP, is led whole sight line place in one's power equably.
The glue frame of known backlight modular structure is in order to fixed light source unit, blooming pieces such as LGP or printed circuit board (PCB); LGP 11 is embedded at module glue frame 12 central authorities, as shown in Figure 1, and light source 13 places a lateral location of glue frame 12, between light source 13 and LGP 11, then keep a space, advancing and reflecting in order to light, yet, the heat of considering LGP 11 problem that rises can be reserved some gaps 14 between this glue frame 12 and the LGP 11, as shown in Figures 2 and 3 usually, when carrying out ray cast, find that light can penetrate LGP 11 avris and arrive module glue frame 12, and be refracted 14 directly ejaculations, and cause light leakage phenomena to the gap, light leakage phenomena can make screen produce bright uneven zone, thereby has reduced display effect.
The utility model content
The technical problem that the utility model solved is promptly providing a kind of glue frame improvement of backlight module, and particularly a kind of side leakage optical phenomenon that improves is guaranteed the glue frame elastic construction of display effect.
The technical solution of the utility model is: a kind of elastic construction of backlight module glue frame, and it includes at least: a LGP, this LGP are provided with a light inlet side and two avris adjacent with the light inlet side; One light source module, this light source module are located at the relative light inlet side of this LGP place; And a glue frame, this glue frame is provided with four sidewalls, and defines an accommodation space between four sidewalls, and this accommodation space wherein is formed with at least one barricade between two avris of this LGP and the sidewall with ccontaining light source module and LGP.
Wherein, this barricade is provided with fixed part and at least one contact site, and this fixed part and this glue frame interfix, and this contact site then contacts with the LGP avris.
The fixed part of this barricade and contact site are formed by this glue frame one extension.
Be formed with hollow bulb between this fixed part and the contact site.
This contact site is formed with plural micro-structural towards hollow bulb.
This hollow bulb has identical width.
This hollow bulb has different width.
It is characterized in that the length of this light inlet side is less than the length of avris.
The beneficial effects of the utility model are:
1, barrier wall structure of the present utility model can reduce the gap of LGP and glue frame, to improve the side leakage optical phenomenon, guarantees display effect.
2, when whole backlight module carries out environmental testing, this hollow bulb provides the elasticity of barricade, can utilize this resilient characteristic can absorb the buckling deformation that LGP raises and produces because of temperature humidity.
