導光板及具有該導光板的背光模塊
The present invention relates to a light guide plate and a backlight module having the light guide, the light guide plate on the upper surface of the structure of a plurality of V-shaped grooves, said V-shaped groove structure has a free surface contour of the gradient, the lower surface of the micro lens array structure . Said V-shaped groove toward the side of the LED light source is a surface contour of the gradient, and the other side is vertical or nearly vertical plane. The top of the V-shaped groove contour line tangent to the surface level of the V-groove angle of more than a bottom surface profile of the horizontal angle of the tangent.Compared with the traditional single dot structure of the light guide plate, using this free surface contour gradient V-shaped groove structure plus network structure more reasonable distribution of light guide plate, and backlight module can at least use less brightness enhancement film layer, so that reduce the cost of the backlight module, while in the case of low power consumption to achieve the desired display brightness.
