Abstract
The utility model relates to liquid crystal module, provides and provides a kind of liquid crystal module, solves the bright border problem that liquid crystal module non-light incidence side occurs.It comprises light guide plate, liquid crystal panel, glue frame, blooming piece, reflecting paper, blooming piece is positioned at above light guide plate, liquid crystal panel is positioned at the top of blooming piece, glue frame is positioned at the side of light guide plate, reflecting paper is positioned at below light guide plate, the side end of light guide plate comprises for the light inlet end face of light inlet and for reflective non-light inlet end face, and non-light inlet end is provided with mirror-reflection sheet.The utility model is applicable to LCD TV, can eliminate the bright border phenomenon of liquid crystal module non-light incidence side, promotes the picture effect of LCD TV.
Description
Technical field
The utility model relates to liquid crystal module, particularly a kind of liquid crystal module.
Background technology
Liquid crystal module for flat panel TV generally comprises light guide plate, liquid crystal panel, glue frame, blooming piece, reflecting paper, light is injected from the side incident end face of light guide plate, turn to and site bottom light guide plate and reflecting paper reflection through light guide plate, light front is penetrated, again through blooming piece, on most Zhongdao liquid crystal panel.At present, in order to prevent light guide plate side light leakage, and improve the efficiency of light energy utilization, usually attach white reflective sheet at the non-light inlet end face of light guide plate, white reflective sheet plays irreflexive effect, along with narrowing gradually of liquid crystal module frame, when the light that LED sends is irradiated to white reflection sheet surface, diffuse light will penetrate from glue edge edge, then penetrates through O/C viewing area, produce brighter edge, affect picture effect.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of liquid crystal module, solves the problem that bright border appears in liquid crystal module non-light incidence side.
For solving the problem, the technical solution adopted in the utility model is: a kind of liquid crystal module, comprise light guide plate, liquid crystal panel, glue frame, blooming piece, reflecting paper, blooming piece is positioned at above light guide plate, liquid crystal panel is positioned at the top of blooming piece, and glue frame is positioned at the side of light guide plate, and reflecting paper is positioned at below light guide plate, the side end of light guide plate comprises for the light inlet end face of light inlet and for reflective non-light inlet end face, and non-light inlet end is provided with mirror-reflection sheet.
Further, described mirror-reflection sheet is silver-colored reflector plate.
The beneficial effects of the utility model are: by arranging mirror-reflection sheet in the non-light inlet end of light guide plate, eliminate the bright border phenomenon of liquid crystal module non-light incidence side, promote the picture effect of LCD TV; And mirror-reflection sheet carries out mirror-reflection, the optical energy loss of liquid crystal module reduces, and light utilization ratio improves.
Accompanying drawing explanation
Fig. 1 is traditional liquid crystal module sectional view;
Fig. 2 is the utility model sectional view.
Number in figure: 1 is light guide plate, and 2 is liquid crystal panel, and 3 is glue frame, and 4 is blooming piece, and 5 is reflecting paper, and 6 is reflector plate, and 11 is light guide plate mesh point, and S is light source.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, traditional liquid crystal module comprises light guide plate 1, liquid crystal panel 2, glue frame 3, blooming piece 4, reflecting paper 5, reflector plate 6, blooming piece 4 is positioned at above light guide plate 1, liquid crystal panel 2 is positioned at the top of blooming piece 4, glue frame 3 is positioned at the side of light guide plate 1, reflecting paper 5 is positioned at the below of light guide plate 1, the side end of light guide plate 1 comprises for the light inlet end face of light inlet and for reflective non-light inlet end face, non-light inlet end is provided with reflector plate 6, reflector plate 6 is white side reflector plate, and described white side reflector plate mainly plays irreflexive effect.Its working condition is: the light that LED light source S sends is injected at the light inlet end face of light guide plate 1, through the total reflection of site and reflecting paper 5, finally be irradiated in the white side reflector plate on non-light inlet end face and produce diffuse reflection, diffuse light is from the edge illumination of glue frame 3 to blooming piece 4, through blooming piece 4 be finally mapped to liquid crystal panel 2 can viewing area, produce bright border phenomenon.
For solving above-mentioned both sides problem, improve as follows: as Fig. 2, the utility model comprises light guide plate 1, liquid crystal panel 2, glue frame 3, blooming piece 4, reflecting paper 5, reflector plate 6, changes the reflector plate 6 of non-for traditional liquid crystal module light inputting end side into mirror-reflection sheet by diffusive reflective plate.Particularly, silver-colored reflector plate is attached at light guide plate 1 non-light inlet end face, the light being irradiated to reflector plate 6 is made to produce mirror-reflection, mirror-reflection light still meets total reflection condition, continue to propagate in light guide plate 1, until the site 11 be irradiated to bottom light guide plate produces diffuse reflection or refraction, light penetrates from liquid crystal module viewing area.
Mirror-reflection sheet eliminates the bright border phenomenon that non-light inlet end face side produces because of diffuse reflection, effectively improves the picture effect of LCD TV; In addition, mirror-reflection sheet carries out mirror-reflection, and therefore during reflection, optical energy loss is little, and light utilization ratio is high, benefits to the brightness improving liquid crystal module.
Claims (2)
