Lamp lens, optical diaphragm group, LED light lens are fixed on backboard by heat-conducting glue band, and optical diaphragm group is two-sided also by shading
Adhesive tape is fixed in glue frame, and liquid crystal display then passes through double-sided adhesive to be fixed with backlight module surrounding.Wherein, diffuser plate major function
It is to scatter incident light sufficiently, realizes softer, uniform radiation response.In general, diffuser plate generally used now be all by
GPPS and light diffusion particle are formed by squeezing, and due to containing light diffusing agent inside light diffusion particle, light diffusing agent is inevitable
Ground can absorb incident light, cause the loss of light after through diffuser plate so as to cause incident light, reduce the utilization rate of light, cause
Light diffusion is uneven.What the matrix resin of this light diffusing particles mainly selected is the engineering of light transmittance height, satisfactory mechanical property
Plastics, and it is more prominent with PMMA, PS, PC etc..And the light diffusing agent in light diffusing particles mainly includes inorganic light diffusing agent, than
Such as barium sulfate, silica and organic light diffusing agent, and based on organic diffusion particle existing for microspheroidal aggregated form.
The in bright gay color degree of liquid crystal display requires higher and higher, this just needs to improve the color gamut value of display device, due to high color
There is the failure area of one fixed width at the membrane cutting edge of domain quantum dot, and the color of the color and other regions that lead to failure area generates
Color difference, colour gamut uniformity are poor.
Utility model content
In view of above-mentioned deficiency present in diffuser plate used in existing backlight module, the utility model technical purpose is
A kind of function diffuser plate of structure novel is provided, by the way that fusion quantum dot is added in diffuser plate, so that light diffusing sheet absorbs not
Visible blue light, compensate in matrix should not micro- yellow light, while reflecting more visible lights, effectively solve the color difference of visible area
Problem, to realize that the colour gamut uniformity of backlight module is high.
In order to achieve the above objectives, the utility model technology will be realized by following proposal：
