Traditional backlight module is shown in Figure 1, and backlight module 100 comprises a light guide plate 10, a light source 20, a reflector plate 30 and several optical sheets 40.Wherein light source 20 is arranged on the side of light guide plate 10, reflector plate 30 is arranged on the below of light guide plate 10, and optical sheet 40 then is arranged on light guide plate 10 tops, and the light that light source 20 sends is via the refraction guiding of light guide plate 10, after reflector plate 30 reflections, penetrate upward by optical sheet 40.In above-mentioned structure, colour temperature as if the light that penetrates for backlight module 100 has different requirements, for example A manufacturer requires the light of colder blue system, and the light that B manufacturer requires inclined to one side warm colour to be, then must provide or make light source with multiple colour temperature, to meet different clients' demand, so can increase the manufacturing cost of backlight module and the numerous and diverse degree in the handling of goods and materials.
Summary of the invention
In view of this, purpose of the present invention is providing a kind of backlight module, only need prepare a kind of light source of colour temperature, and comes the colour temperature of light that light source is sent to finely tune by a chromatograph is set.
One preferred embodiment of backlight module of the present invention comprises: a light guide plate, a light source, a reflector plate and a chromatograph.Light source is arranged on the side of light guide plate, and reflector plate is arranged on the below of light guide plate, and chromatograph has a set color, and is arranged on the below of reflector plate, makes reflector plate between light guide plate and chromatograph.The light that sends from light source wherein, after the light guide plate refraction, the light penetration reflector plate of part, and by the chromatograph reflection and produce a shade, the coloured light of generation mix with the light that light source sends and feasible light from the light guide plate ejaculation has desirable color.
In above-mentioned preferred embodiment, this chromatograph can be opaque.The material of chromatograph can be paper or saturated polynary ester (PET).
In above-mentioned preferred embodiment, chromatograph can be formed on the back side of reflector plate.
Above-mentioned preferred embodiment also comprises a housing, is located at the below of reflector plate, and chromatograph can be formed on the inboard of housing.Wherein chromatograph can be formed on the inboard of this housing by the mode of printing or sputter.
For above and other objects of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.

Embodiment
Fig. 2 is the synoptic diagram of a preferred embodiment of the present invention.Fig. 3 is the enlarged drawing of A part among Fig. 2.Backlight module 200 of the present invention comprises a light guide plate 10, a light source 20, a reflector plate 30, a plurality of optical sheet 40 and a chromatograph 50.Light source 20 is arranged on the side of light guide plate 10, and reflector plate 30 is arranged on the below of light guide plate 20, and optical sheet 40 is arranged on the top of light guide plate 10, and chromatograph 50 has set color and is arranged on the below of reflector plate 30.
Because the material of reflector plate 30 is used the saturated polynary ester (PET) of white mostly, therefore after the light that sends from light source 20 reflects via light guide plate 10, most light (90%～95%) sheet 30 reflection that can be reflected, shown in Fig. 3 arrow a, small part (about 5%～10%) meeting penetrate through reflective sheet 30 is shown in arrow b.The light b of penetrate through reflective sheet 30 shines chromatograph 50, and by chromatograph 50 reflections, light by chromatograph 50 reflections is the coloured light with set color, behind this coloured light partial penetration reflector plate 30, therefore the light a that is reflected with reflector plate 30 mixes, and penetrates to the light of optical sheet 40 from light guide plate 10 and just is adjusted to desirable coloured light.
Chromatograph 50 can be opaque material, in order to avoid background light penetration and influence the color of light.The material of chromatograph 50 can be paper, saturated polynary ester (PET) etc.Therefore for the requirement of the light of different-colour, only need to change a chromatograph and get final product, need not prepare or make the light source of light with various different-colours.
Fig. 4 is another embodiment of backlight module of the present invention.In backlight module 300, chromatograph 50 is the back side that is formed on reflector plate 30 in the mode of printing or sputter, the light of penetrate through reflective sheet 30 can be by chromatograph 50 reflections that are formed on reflector plate 30 back sides, so also can reach the effect of adjusting the light colour temperature, for different demands, only the reflector plate 30 that needs preparation to be formed with different colours gets final product, and need not prepare or make the light source of the light with various different-colours.
Fig. 5 is another embodiment of backlight module of the present invention.In backlight module 400, chromatograph 50 is to be formed on housing 60 inboard of backlight module 400 and toward reflector plate 30 with the printing or the mode of sputter, so also can reach the effect of adjusting the light colour temperature, for different demands, only the housing 60 that needs preparation to be formed with different colours gets final product, and need not prepare or make the light source of the light with various different-colours.
Backlight module of the present invention can be applied in the display apparatus module.As shown in Figure 6, the backlight module of the above embodiment of the present invention (for example backlight module 200) can be incorporated into panel 500, is the light source of panel 500, and constitutes a display apparatus module 600.
As shown in Figure 7, above-mentioned display apparatus module 600 can be applicable in the electronic installation 800, and in this electronic installation 800, this display apparatus module 600 is coupled to an input block 700,700 pairs of these display apparatus modules 600 of this input block provide input, make this display apparatus module 600 show images.
Above-mentioned electronic installation 800 can be mobile phone (mobile phone), digital camera, personal digital assistant (PDA; Personal digital assistant), notebook, desktop PC, televisor, automobile-used display or Portable DVD player (portable DVD player).
Though the present invention with preferred embodiment openly as above; right its is not in order to qualification the present invention, any insider, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
