Abstract
The present invention relates to an optical diaphragm for an edge-lit back light module. The module at least comprises a light guide plate, a reflection diaphragm, a plurality of optical diaphragms and a lamp source. One surface of the optical diaphragm is provided with a plurality of stripe miniature light guide bodies. Each light guide body is provided with a plurality of summits. The heights of the summits are not consistent and in the state of different heights. Any one of the higher summit and the lower summit can respectively be in left and right continuous bending or up and down continuous fluctuation shape.

Description
Technical field
The present invention relates to a kind of blooming piece of side light type back light module, refer to especially make the unlikely too systematicness that presents of the light source that leaves, to help the utilization of follow-up light source in making light source after its effect.
Background technology
The light source of one Thin Film Transistor-LCD (TFT-LCD) is to rely upon a backlight module (Back light Module) to be provided, this backlight module then must make the light source that provides reach all neat degree and the brilliant degree of high-quality, just can be enough to obtain good subsequent applications effect.
Wherein, as shown in Figure 1, a backlight module 1 includes at least: a light guide plate 11, a reflection diaphragm 12, a plurality of blooming piece 13, and, lamp source 14; Light guide plate 11 has at least one incidence surface 111, and a reflecting surface 112 and an exiting surface 113, and this incidence surface 111 is still in order to accepting the light source that send in lamp source 14, and makes this light source towards light guide plate 11 internal delivery.112 direct of travels that source reflection can be changed light source of this reflecting surface.And in reflecting surface 112 and be provided with a lot of leaded light points 1121, utilize these leaded light points 1121 more can destroy the light total reflection condition, make its light source more reach the even effect of reflex time, 113 of exiting surfaces are in order to externally to export the light source in the light guide plate 11; One reflection diaphragm 12 is reflecting surface 112 outsides that are flat on light guide plate 11, doing reflection and return among the light guide plate 11 leaking out the outer light sources of light guide plate 11; A plurality of blooming pieces 13 are to be arranged at outside the exiting surface 113 of light guide plate 11, these blooming pieces 13 promptly have the diffusion barrier sheet (Diffusion film) 131 that can make light source do diffusion effect, and can make light source do the prism diaphragm of optically focused usefulness (Pism film) 132, and look actual required situation, and change the setting of being arranged in pairs or groups with different quantity and mutual configuration order respectively, wherein, the prism cylinder 1321 of extremely how trickle shape is gone up and is formed with on one surface of prism diaphragm 132, and these prism cylinders 1321 and line spread are on the surface of prism diaphragm 132, and be vertical each other mode with the prism cylinder 1321 in the two prism diaphragms 132 and dispose, to reach optically focused usefulness to the light source all directions; 14 in lamp source is the main source of light source, mainly is arranged at outside incidence surface 111 places of light guide plate 11, and its usage quantity is then done allotment according to commodity code requirement difference.
In addition, as shown in Figure 2, developed another backlight module 2 in the recent period, this backlight module 2 includes at least: a light guide plate 21, a reflection diaphragm 22, a prism diaphragm 23, a protection diaphragm 24 and a lamp source 25; Light guide plate 21 has an incidence surface 211, a reflecting surface 212 and an exiting surface 213 at least; Wherein, incidence surface 211 is in order to accepting the light source of lamp source 25 output, and 212 of reflectings surface can will be penetrated and do reflection in this light source, and externally output is used with the light sources of light guide plate 21 inside for 213 of exiting surfaces.This exiting surface 213 also is formed with a lot of the prism cylinders 2131 of shape side by side, thus so that light source when leaving light guide plate 21, promptly be subjected to these prism cylinders 2131 to do usefulness, and reach the action of optically focused, and the light source after leaving light guide plate 21, and after being subjected to the optically focused of prism cylinder 231 other directions on the prism diaphragm 23 again, finish the optically focused usefulness of all directions to make this light source.
And, can reach effective optically focused usefulness of light source because of the prism diaphragm 21 in the backlight module 2 only must use one, can effectively reduce cost, so gradually be subjected to the glad employing of relevant dealer.
Yet as shown in Figure 3, though the light source of backlight module 2 outputs is transformed into flat light source from linear light sorurce in above-mentioned, Zheng Ti light source is still the effect that is subjected to prism cylinder 231 on the prism diaphragm 23 in fact, forms a rectilinear light beam that has systematicness and advances; Thin film transistor (TFT) (Thin Film Transistors in other liquid crystal panel 3; TFT) 31 and colored filter (Color Filter; CF) 32 is the matrix form configuration formation of superfine microfacies correspondence, so being is the rectilinear light beam that has systematicness, in case during again by the gap between each unit in thin film transistor (TFT) 31 and the colored filter 32, promptly can make this light beam that passes through produce diffraction (diffraction), and be formed with interference fringe 33 on this liquid crystal panel 3.The eventually performance when destroying liquid crystal panel 3 and show.
Formation phenomenon for above-mentioned interference striped 33, when general backlight module factory finishes this backlight module in group is upright, still can't learn the situation that whether has its generation, and must deliver goods to liquid crystal panel factory through organize upright after, just can learn when activating the demonstration of liquid crystal panel, so, the puzzlement that this often causes backlight module factory and the two side dealers of liquid crystal panel factory to cooperate, and extremely to be overcome.
Summary of the invention
The present invention aims to provide the blooming piece of relevant a kind of side light type back light module, this blooming piece can make the light source through its effect be a non-extremely uniform rectilinearity light beam, when making the light source of the backlight module output of this application give liquid crystal panel, make this liquid crystal panel when showing, not have the generation of interference fringe, and the performance when being beneficial to liquid crystal panel and showing.
For this reason, fundamental purpose of the present invention, be wherein to be provided with the miniature light conductor of a plurality of strips in a surface in this blooming piece, each miniature light conductor has the peak more than two or two, and the peak of this miniature light conductor is to be the state that height differs, wherein, any one of peak or ebb can be left and right sides continuous bend or the height design of fluctuating continuously up and down respectively, thus, make the light beam of its effect bright dipping also be linear regular shape no longer entirely, but include the light beam that is the curved formation of Curved Continuous and export, produce the phenomenon of interference fringe when avoiding follow-up liquid crystal panel to show.
Another object of the present invention, aim to provide the blooming piece of relevant a kind of side light type back light module, a this blooming piece wherein surface is provided with the miniature light conductor of a plurality of strips, each miniature light conductor has the peak more than two or two, and the peak of each miniature light conductor system is the state of equal height, wherein, each peak of this miniature light conductor can partly or all be left and right sides continuous bend or the height design of fluctuating continuously up and down, thus, make the light beam of its effect bright dipping also be linear regular shape no longer entirely, but include the light beam that is the curved formation of Curved Continuous and export, produce the phenomenon of interference fringe when avoiding follow-up liquid crystal panel to show.
