At first the present invention has described a kind of backlight module, has comprised single led light source, LGP, light-strip, spectrum groupware, and display floater.Wherein, the single led incident light source that sends is after incident light source enters spectrum groupware, by minute light action (spectrum groupware can make the transmission of part light, part light reflection) of spectrum groupware.Output outgoing light source, and make the outgoing light source see through uniformly exiting side.And in the same leaded light of LGP lower surface site, when transmitted light arrived the leaded light site, the diffuse reflection effect of the leaded light site by LGP was evenly distributed on LGP transmitted light, and then is evenly distributed on display floater.
Below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail, be to be understood that specific features in the embodiment of the present invention and embodiment is the detailed explanation to technical solution of the present invention, rather than to the restriction of technical solution of the present invention, in the situation that do not conflict, the technical characterictic in the embodiment of the present invention and embodiment can make up mutually.
Embodiment one:
In the embodiment of the present application, provide a kind of backlight module.
In the embodiment of the present application, backlight module as shown in Figure 2, has comprised light source region A and viewing area B in terms of overall.Wherein, light source region A is present in the side of viewing area B.Light source region A has comprised single led light source 1, light-strip 3, lens 6 etc.Viewing area B has comprised LGP 2 and display floater 5.
Concrete, please refer to Fig. 3, backlight module comprises: single led light source 1, LGP 2, light-strip 3, spectrum groupware 4, and display floater 5.
Concrete, single led light source 1 is used for sending incident light source.
LGP 2 is built-in with leaded light site 21.
Light-strip 3 is arranged between single led light source 1 and LGP 2, and light-strip 3 has light incident side 31 and exiting side 32.
Concrete, light-strip 3 has four sides: light incident side 31, exiting side 32, and the other dual-side that is different from light incident side 31 and exiting side 32.
Spectrum groupware 4 is arranged in light-strip 3.
In addition, backlight module also comprises: lens 6, be present between single led light source 1 and light-strip 3, and be used for incident light source is scattered in spectrum groupware 4.
In addition, the particular location of light-strip 3 is sides that are positioned at LGP 2, and is the side that exiting side 32 is relatively got close to LGP 2.And, also be built-in with leaded light site 21 in light-strip 3.Leaded light site 21 is built in the other dual-side that light-strip 3 is different from light incident side 31 and exiting side 32.
And for spectrum groupware 4, spectrum groupware 4 specifically can be carried out light splitting to the light source that shines on spectrum groupware 4 by transmission or reflection, makes the outgoing light source see through uniformly the exiting side 32 of light-strip 3, and enters LGP 2 from the side of LGP 2.
Concrete, spectrum groupware 4 can reflect for the incident light source of certain some angle, and for the incident light source of some ad-hoc locations, can carry out transmission.
Concrete, in the embodiment of the present application, spectrum groupware 4 can be the isosceles wedge-shaped slot.The isosceles wedge-shaped slot can be the prism form, also can be the form of isosceles trapezoid.What describe in Fig. 3 is exactly for the isosceles wedge-shaped slot of prism form, and two isosceles sides of this isosceles wedge-shaped slot are smooth, two isosceles sides of isosceles wedge-shaped slot carry out light splitting to the incident light source that shines on it respectively, make the outgoing light source see through uniformly the exiting side 32 of light-strip 3, and enter LGP 2 from the side of LGP 2.
In addition, if incident light source enters prism from the summit of prism, because the prism top has as the Fillet Feature 401 in Fig. 4, can directly enter into the exiting side 32 of light-strip 3 from the base of prism.
Certainly, two isosceles sides of isosceles wedge-shaped slot can also be rough, for example, on two isosceles sides, small-sized wedge-shaped slot can also be set, by small-sized wedge-shaped slot, incident light source is carried out light splitting, make the outgoing light source see through uniformly the exiting side 32 of light-strip 3, and enter LGP 2 from the side of LGP 2.
Above-described is the concrete structure of backlight module, and under the support of this structure, the incident light source that single led light source 1 sends can be radiated on display floater 5 uniformly.
The below introduces the enforcement principle of backlight module.
At first, when single led light source 1 sent incident light source, the light incident side 31 of light-strip 3 was accepted incident light source, and incident light source is shone on spectrum groupware 4.
In addition, enter into light incident side 31 in order better to make incident light source, between single led light source 1 and light-strip 3, also be provided with lens 6, be used for enlarging original single led rising angle, incident light source is scattered on spectrum groupware 4.
Then, by minute light action of spectrum groupware 4, output outgoing light source, and make the outgoing light source see through uniformly exiting side 32.
Concrete, for spectrum groupware 4, can transmission or the light source of reflected illumination on the spectrum groupware 4, make the outgoing light source see through uniformly the exiting side 32 of light-strip 3, and enter LGP 2 from the side of LGP 2.If the words that spectrum groupware 4 is described with the isosceles wedge-shaped slot that represents in Fig. 3, incide the light source of two isosceles sides of isosceles wedge-shaped slot, can be by two isosceles sides light splitting of isosceles wedge-shaped slot, make the outgoing light source that forms after light splitting see through uniformly the exiting side 32 of light-strip 3, and enter LGP 2 from the side of LGP 2.And incide the light source on the summit of isosceles wedge-shaped slot, can directly through the isosceles wedge-shaped slot, enter into the exiting side 32 of light-strip 3 from its base, and enter LGP 2 from the side of LGP 2.
In addition, the exiting side 32 that the light of spectrum groupware 4 reflections has not necessarily all entered light-strip 3, some incident light sources might be reflected to the other dual-side of light-strip 3, perhaps turn back to the light incident side 31 of light-strip 3.For the other dual-side that reflexes to light-strip 3, this moment, these two sides were provided with leaded light site 21, by the diffuse reflection effect of leaded light site 21, will shine the light source diffuse reflection of leaded light site 21 to exiting side 32.The light source that reflexes to light incident side 31 does not belong to the application's protection domain.
Then, the transmitted light that appears from the side of LGP 2 can enter LGP 2.
When transmitted light arrived leaded light site 21, the diffuse reflection effect of the leaded light site 21 by LGP 2 was evenly distributed on LGP 2 transmitted light, and then is evenly distributed on display floater 5.
