Room temperature, obtains nanometer grating structure composite blue light diffusion barrier；The mass ratio of each component is distilled water wherein in poly-vinyl alcohol solution: poly-
Vinyl alcohol: boric acid=100: 10: 0.2, the weight average molecular weight of polyvinyl alcohol is 12000；Nanometer light is detected with transmission measurement instrument
The blue light of grid structure composite blue light diffusion barrier, feux rouges, green glow, white light transmitance；Nanometer grating structure composite is detected with haze meter
Blue light, feux rouges, green glow, the white light mist degree of blue light diffusion barrier；By the blue light that excitation is 0.80, feux rouges, green glow, white light through nanometer
Optical grating construction composite blue light diffusion barrier is transmitted, and the excitation of transmitted light is measured with color illumination tester.
