Description
[technical field]
The present invention relates to a kind of module backlight.
[background technology]
Along with science and technology is showing improvement or progress day by day, recently liquid crystal indicator is to lightening and large scale development, from being applied to field of mobile telephony to being applied to the graphoscope field, lcd technology has been applied to TV domain now, and LCD TV also frequently comes across in people's the life.Along with the continuous increase of liquid crystal indicator size, also will be as the module size backlight of its light-source system along with increase.Diffuser plate is the significant components in the module backlight, in order to will evenly spreading outgoing from the light beam that light source sends, makes liquid crystal indicator even brightness purpose to reach.
A kind of prior art light diffusing sheet can be consulted disclosed TOHKEMY 2000-298203 communique on October 24th, 2000.The planar structure of this light diffusing sheet as shown in Figure 1, this light diffusing sheet 10 comprises a transparency carrier 11, these transparency carrier 11 surfaces are formed with a light diffusion layer 12, this light diffusion layer 12 comprises a light-transmissive resin 13 and light diffusion particle 14, and this light diffusion particle 14 is that condensate particle 14a and silicon dioxide granule 14b mix by silicones.
These light diffusing sheet 10 sizes are single, and it is only applicable to the module backlight and the liquid crystal indicator of single size, so these light diffusing sheet 10 scope of applications are little.Along with the continuous increase of liquid crystal indicator size, the former of making this light diffusing sheet 10 also needs to make the idleness of equipment along with replacing, and the waste resource increases manufacturing cost.
[summary of the invention]
The present invention also provides a kind of module backlight of diffuser plate of applied widely, low cost of manufacture.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of module backlight is provided, it comprises a diffuser plate, one light source, an one glue frame and a reflecting plate, this light source is arranged between this diffuser plate and this reflecting plate, this diffuser plate is accommodated and held to this glue frame, this diffuser plate comprises a plurality of support components that light spread the diffusion unit of outgoing and be used to support this diffuser plate, be provided with the bindiny mechanism that is used to cooperatively interact and connects between the two adjacent diffusion units, this bindiny mechanism comprises a two triangle coupling bar that has the two-way connector of two triangle link slot and be arranged at two adjacent diffusion units respectively and match with this two link slot, these a plurality of support components are arranged at the junction between the two adjacent diffusion units respectively, and this diffuser plate is supported on this reflecting plate.
Compare with prior art, the invention has the beneficial effects as follows: the diffuser plate of the present invention's module backlight comprises a plurality of diffusion units that light spread outgoing, be provided with the bindiny mechanism that is used to cooperatively interact and connects between the two adjacent diffusion units, this bindiny mechanism cooperates support component with the glue frame undersized diffusion unit to be combined, and can increase or reduce the quantity of diffusion unit according to the size of liquid crystal indicator size, the size of diffuser plate and the size of liquid crystal indicator are complementary, so, this diffuser plate can be used in the module backlight and liquid crystal indicator of different size, and its scope of application is wider.
This diffuser plate is combined by a plurality of diffusion units, when the diffuser plate that need produce large-size when liquid crystal indicator is complementary with it, makes the originaling forming equipment of this diffuser plate and need not change, and the quantity that only needs to increase diffusion unit gets final product.So same former can be made the diffuser plate of different size, improved the availability of equipment, reduced manufacturing cost.
