Description

A kind of backlight module

Technical field

This utility model relates to art of display device manufacture, concretely relates to a kind of backlight module.

Background technology

Along with the development of liquid crystal technology, liquid crystal display obtains commonly used in fields such as computer, mobile phone, TVs, owing to display panels itself does not have photism, it is therefore desirable to arranges backlight module behind at liquid crystal display and provides uniform light source for it. LED has feature pollution-free, that volume is little, vibration resistance, low energy consumption high-efficiency are luminous, becomes the light source being widely used in LCD backlight module. The quality of backlight determines the important parameters such as the brightness of liquid crystal display, color range, has been largely fixed the illumination effect of liquid crystal display. Along with the requirement of energy-saving and emission-reduction is improved constantly by people, the energy consumption how reducing backlight becomes the emphasis that people pay close attention to, in order to save the energy, it is thought that utilize reflector plate to be folded into some convex ridges, LED light source is arranged on the both sides of convex ridge, as shown in Figure 1, original emitting cavity is divided into some string light chambeies 102 by the convex ridge 101 after reflector plate 100 is folding, which enhance the utilization rate of light, but the shortcoming of this structure is in that, the light source that this backlight module provides is banding, can only control the brightness of whole piece LED light source, it is impossible to control the brightness of every LEDs.

Utility model content

For solving the problems referred to above, this utility model provides a kind of backlight module, provides an independent emitting cavity by utilizing the first reflector plate and the second reflector plate to cut to be folded into each lamp bead, can be effectively improved the utilization rate of light, make light spread more uniform.

This utility model provides a kind of backlight module, this backlight module includes glue frame, backboard, the lamp bar, diffuser plate and the blooming piece that are fixed on backboard, lamp bar is provided with multiple lamp bead, this backlight module also includes the first reflector plate and multiple second reflector plate, first reflector plate is folded to form the groove of multiple lengthwise, one first convex ridge is formed between adjacent two grooves, second reflector plate is folded into the second convex ridge, placing multiple second reflector plates in each groove so that groove to separate the multiple emitting cavities of formation, each lamp bead is contained in an emitting cavity of correspondence. The groove of the first reflector plate includes base plate and is positioned at the coaming plate of base plate outside. First convex ridge and the second convex ridge are inverted V-shape.Being provided with some gaps in each groove of the first reflector plate, corner, the bottom place of the second reflector plate is provided with lug, and lug is fixed in the gap of the first reflector plate. First convex ridge of the second reflector plate and the first reflector plate is mutually perpendicular to. A circular hole supplying lamp bead traverse it is provided with in each emitting cavity. Diffuser plate and blooming piece are placed in the surface of described emitting cavity, and glue frame and backboard are fixed diffuser plate and blooming piece.

This utility model provides an independent emitting cavity by utilizing the first reflector plate and the second reflector plate to cut to be folded into each lamp bead, can be effectively improved the utilization rate of light, make light spread more uniform, improve the display effect of display.
