Description
Technical field
The present invention relates to a kind of liquid crystal indicator, relate in particular to a kind of liquid crystal indicator that uses reflective brightness enhancement film.
Background technology
Along with the rapid development of network and radio communication technology, information is talked about and is popularized gradually in the individual, so portable information product, like notebook computer, mobile phone, digital camera and personal digital assistant etc., and all fast-developing and growth.Because LCD (Liquid Crystal Display; Be abbreviated as LCD); Have slimming, lightweight, low power consumption, radiationless pollution, and can be compatible etc. with manufacture of semiconductor advantage, and complying with the rise in the information-based market of this strand network digital; Make it short three during the decade, the application of product more is tremendous growth.
In the structure of LCD (LCD), because liquid crystal itself does not have the characteristics of luminescence, and need to provide the light source of demonstration by module backlight, the luminescence component of use and selecting for use of blooming piece are then depended in the brightness of module backlight.Because LCD generally all utilizes the adjustment mechanism of the polar biased characteristic of light as brightness, so generally speaking must cause the loss of most energy of light source; And the reflective brightness enhancement film (Dual Brightness Enhanced Film is abbreviated as DBEF) of 3M exploitation can penetrate or reflect utilization again to the light of different directions polarization state, can reach the function that energy of light source effectively utilizes.
In the general back light module unit structure, the blooming piece of the superiors is a diffusion barrier sheet, has the lifting homogeneity on its function; And the effect of anti-edge light leak, on the way of taking precautions against the edge light leak, can be employed in the diffusion sheet edge according to the demand width; But the color of printing shading generally mostly is that grey or black, form can be full version or mode gradually layer; Can be continuous or local distribution mode in the design, reaching and covering the light leak path is purpose.Because when using reflective brightness enhancement film (DBEF); Need the polaroid on the collocation liquid-crystalline glasses to use, so on the storehouse of module blooming piece backlight, must be positioned over the superiors of module backlight; Promptly adjacent with following polaroid, feed back the effect that reaches blast in order to the luminous energy polarization.Owing to must replace the position framework of going up diffusion sheet, then, can't reach the effect of covering leakage with the mode of diffusion sheet edge printing for the path position of possibility light leak.
In view of this, how designing a kind of liquid crystal indicator, using reflective brightness enhancement film (BDEF) simultaneously, can also reach the effect of covering light leak, is the problem that those skilled in the art need solution badly.
Summary of the invention
In prior art, during the reflective brightness enhancement film of the use of existence (BDEF), the superiors of module backlight be placed, thereby the defective of the effect of covering light leak can't be reached, the invention provides a kind of liquid crystal indicator.
According to the present invention a kind of liquid crystal indicator is provided, comprises liquid crystal panel and module backlight.Liquid crystal panel comprises Polarizer.Module backlight is arranged at down the below of Polarizer, comprises LGP, reflective brightness enhancement film, a plurality of optical film and light shield layer.Reflective brightness enhancement film is down between Polarizer and the LGP; A plurality of optical films are between reflective brightness enhancement film and LGP; Light shield layer is covered in the edge of reflective brightness enhancement film.
Preferably, module backlight more comprises a glue frame, and the glue frame has horizontal part and vertical portion, and horizontal part sets up liquid crystal panel.
Preferably, module backlight more comprises a chase, is positioned at the below of glue frame, and chase has a holding space for holding LGP.
Preferably, module backlight more comprises a light source, is arranged at the side or the below of LGP.
Preferably, module backlight more comprises a circuit board, and light source is arranged on the circuit board.
Preferably, a plurality of optical films comprise prismatic lens, diffusion sheet or their combination.
Preferably, module backlight more comprises a reflector plate, is positioned on the lower surface of LGP.
Preferably, the color of light shield layer is grey or black.
Preferably, light shield layer through full version or gradually the mode of layer be printed in the edge of reflective brightness enhancement film.
Preferably, light shield layer distributes with continuous or local mode.
Adopt the present invention, not only can utilize reflective brightness enhancement film to play the effect of blast, can also play the effect of covering light leak through printing light shield layer at reflective brightness enhancement film edge.
Description of drawings
The reader with reference to advantages after the embodiment of the present invention, will become apparent various aspects of the present invention.Wherein,
Fig. 1 shows the sectional view of liquid crystal indicator in the prior art.
Fig. 2 shows the sectional view according to liquid crystal indicator of the present invention.
Embodiment
With reference to the accompanying drawings, specific embodiments of the invention is done further to describe in detail.
Fig. 1 shows the sectional view of liquid crystal indicator in the prior art.With reference to Fig. 1, liquid crystal indicator 1 comprises: liquid crystal panel 100 and module 101 backlight.Liquid crystal panel 100 comprises that Polarizer 102 is positioned on the lower surface of liquid crystal panel 100.Module 101 backlight is positioned at the below of Polarizer 102 down, comprising: glue frame (not indicating), optical diaphragm group (not indicating), LGP 103, reflector plate 104, light source 105 and chase 106.The glue frame has horizontal part 107 and vertical portion 108, and horizontal part 107 sets up liquid crystal panel 100.Optical diaphragm group is positioned at the below of Polarizer 102 down, and its superiors are a reflective brightness enhancement film 109.LGP 103 is positioned at the below of optical diaphragm group, and reflector plate 104 is arranged on the lower surface of LGP 103.Light source 105 is positioned at LGP 103 1 sides.Chase 106 is positioned at the below of glue frame, and has an accommodation space, and LGP 103 is placed in this accommodation space with light source 105.The light 110 that sends from light source 105 sees through LGP 103, and the edge that transfers to reflective brightness enhancement film 108 is revealed away, therefore can cause the light leak problem.
Fig. 2 shows the sectional view according to liquid crystal indicator of the present invention.With reference to Fig. 2, liquid crystal indicator 2 comprises liquid crystal panel 200 and module 201 backlight.Liquid crystal panel 200 comprises Polarizer 202.Module 201 backlight is arranged at down the below of Polarizer 202, comprises LGP 203, reflective brightness enhancement film 204, a plurality of optical film 205 and light shield layer 206.Reflective brightness enhancement film 204 is down between Polarizer 202 and the LGP 203.A plurality of optical films 205 are between reflective brightness enhancement film 204 and LGP 203, and a plurality of optical films 205 can be for example prismatic lens, diffusion sheet or their combination of stack successively.Light shield layer 206 is covered in the edge of reflective brightness enhancement film 204; Its color can be black or grey; Light shield layer 206 can through full version or gradually the mode of layer be printed on the edge of reflective brightness enhancement film 204, and can distribute with continuous or local mode, realize the effect of shading.
