Abstract
The utility model is applied to a pastern frame of backlight modules. The improved pastern frame is provided with a lampshade and a light source, wherein a light guiding board is inserted by the opening end of the lampshade and further positioned on one side of the lampshade, the light source enters into the utility model through one side of the light guiding board to make beams of the light source cast along the expecting emitting direction. Wherein, a jointing brim on the pastern frame and close to the light guiding board is provided with a light shading component to weaken the reflectivity of the light guiding board after emitting beams, thus the interference of beams in the light guiding board is reduced and the happening of dark bright ripples is also reduced.
Description
Technical field
The utility model relates to the structural improvement of glue frame, aim to provide a kind of adhesive frame structure that is used for backlight module, can weaken the reflectivity after the light guide plate bright dipping, the interference of light in light guide plate reduced, and can reduce the adhesive frame structure improvement that the phenomenon of dark bright ripple takes place.
Background technology
Press, generally be applied in the LCD of massaging device, can be according to the demand of actual design, and select to utilize the backlight module framework of straight-down negative or side-light type; As shown in Figure 1, be the basic structure synoptic diagram of a side light type back light module framework, it mainly is provided with light source 20 in a lampshade 12, and the plate end of a light guide plate 30 is set in the openend of lampshade 12, light guide plate 30 tops then are provided with several pieces of blooming pieces 50 and liquid crystal panel 60 in regular turn, to allow the light of light source 20 go into light guide plate 30 and penetrate, to reach the effect that liquid crystal panel 60 shows towards the plate face of light guide plate 30 expection from the plate end-fire; Wherein, diffusion sheet 51, brightening piece 52 and last diffusion sheet 51 are arranged at light guide plate 30 tops in regular turn under each blooming piece 50 general using, to increase the diffusion effect of light sources to reach equal light effect by each blooming piece 50.
Moreover its whole backlight module also can be assembled in the glue frame 13, as shown in Figure 2, and to reach the effect of overall package location; Yet, general glue frame utilizes white material to constitute more, its for the light guide plate bright dipping after light reflection mode, cause light and light working direction after the reflection to overlap to form interference easily, its main because difference of its Z-direction flatness of white size frame and molding materials polymerization makes and line reflection route inequality after the light guide plate bright dipping causes overlapping interference, and further be developed on the light-emitting area, and then form the phenomenon existence that light-emitting area has dark bright ripple.
The utility model content
In view of this, the utility model is used for the adhesive frame structure improvement of backlight module, and purpose is promptly in the phenomenon that solves the dark bright ripple in aforementioned backlight module edge, and improves the display quality of backlight module.
The utility model is used for the fundamental purpose of the adhesive frame structure improvement of backlight module, be provided with a lampshade and light source in this glue frame, and light guide plate is positioned a side of lampshade by the openend plant of this lampshade, its light source is entered by a side of light guide plate, to allow the light of light source be able to throw towards the ejaculation direction of expection; Wherein, be provided with light shield device on this glue frame and near the light guide plate trip edge,, the interference of light in light guide plate reduced, and the phenomenon that can reduce dark bright ripple takes place to weaken the reflectivity after the light guide plate bright dipping.
The beneficial effect that the utility model is used for the adhesive frame structure improvement of backlight module is: can obtain a kind of adhesive frame structure that is used for backlight module, can weaken the reflectivity after the light guide plate bright dipping, the interference of light in light guide plate reduced, and can reduce the adhesive frame structure improvement of the phenomenon generation of dark bright ripple.
