Embodiment Construction
[0042] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the detailed description of the embodiments is as follows.
[0043] see Figure 1A and Figure 1B , are respectively a side view of a single light source of the first embodiment of the backlight module of the present invention and a perspective view of the light guide plate structure of the first embodiment of the backlight module of the present invention. like Figure 1A and Figure 1B As shown, the backlight module 100 includes a light guide plate 120 and several light sources 130 . The light guide plate 120 has a light exit surface 122 and a light incident surface 124, and on a bottom surface opposite to the light exit surface 122, several inverted V-shaped light guide portions 126 are formed. The inverted V-shaped light guide portions 126 are formed on the light guide plate 120 The bottom surface faces the groove of the light-emitting surface 122, an...

There is a sort of back-light module and it has a light board and several powers. This light board consists of a out-light face, several in-light faces which circles the out-light face and the array which are fixed in light part of the underside which correspond the out-light face. This array light part which corresponds to a dummy centre of a circle forms a concentric circular arc light groupware, and the dummy center of a circle of every light groupware locates this outboard of the in-light face. This several light power correspond to every light groupware respectively, and the dummy centerof a circle of every light groupware casts a ray to the one of the in-light face in order to make the ray which is cast by every light power to be load by each corresponding light groupware, the wavelength of the ray which is cast by every light power is unequal to wavelength of the ray which is cast by else light power.
Description
technical field [0001] The invention relates to a backlight module, in particular to a backlight module using light-emitting diodes to improve the color saturation of a liquid crystal display. Background technique [0002] With the rapid development of science and technology and the rapid development of the Internet, multimedia technology, and image data transmission, people's demand for multimedia displays is increasing. In recent years, due to the thinness, light weight and portability of liquid crystal displays, and the advantages of low radiation compared with traditional image tube (Cathode Ray Tube; CRT) displays, the demand has increased rapidly and has been widely used in monitors. Notebook computers, digital cameras and other consumer electronics industries. It has gradually become the mainstream of display products. [0003] The backlight module is one of the key components of the liquid crystal display module (LCD module). Since the liquid crystal itself does no...
