Refer to Fig. 1, Fig. 1 is the structural representation of novel backlight module in this utility model embodiment
Figure.
This utility model provides a kind of novel backlight module, and this backlight module is applied to show skill
In art field, it is by the structure optimization to traditional backlight plate, it is possible to ensureing its display brightness
On the premise of, that reduces light source arranges quantity, thus reduces the purpose of production cost.
Specifically, this utility model includes light guide plate 1 and light source 2, in the prior art,
Light guide plate all uses the sheet material design of rectangular configuration, the i.e. design of rectangle sheet material or square,
Wherein, the light guide plate with rectangle sheet material is in the majority.As a example by the light guide plate of rectangle structure design,
In traditional design, arrange many in a long limit of light guide plate and the marginal position of a minor face
Individual LED light source, LED light source quantity is set typically between 64-78, so, not only
Can cause light source that quantity is set too much, the problem that production cost is bigger, the most also can make screen
Display brightness excessive and easily cause visual fatigue.
Based on traditional light guide plate, this utility model is particularly limited to: light guide plate 1 is rectangular plate type
Structure, formation of cutting sth. askew at four drift angles of light guide plate 1 is installed side a, is installed side a and lead
Angle angular range between the side of tabula rasa 1: 40-50 °, and, light source 2 is LED light
Source, light source 2 is arranged on installation side a.
This utility model can carry out cutting to conventional light guiding plate and make, length that will be traditional
Four clipped corners of the light guide plate of square plate construction；Can also be directly to become according to template construct
Type.
