Does anyone know the effect of nano-protection of film-coated mobile phones?

Membrane knot "mobile phone nano-protection is an entrepreneurial project with public welfare nature." Its purpose is to change the way people use mobile phone film with our products, so that customers can use a clean, bright, green and healthy product every day. Film junction nano-protection is to protect the screen of mobile phone, and more importantly, to protect people's eyes, double protection! Its main component is nano silicon dioxide, which is 8- 10 nm. Sticking it on the screen of mobile phone can improve the screen's friction resistance, touch sensitivity, easy cleaning and eye protection, because it contains blue light agent, which is an international advanced blue light blocking technology, which can disperse blue light and reduce the harm of blue light to eyes, and has won the national patent. The nano-protective effect of the film-coated mobile phone on the mobile phone screen has the following effects: 1 effectively improving the screen wear resistance; Effectively disperse blue light, relieve eye fatigue and protect eyes; 3. Smooth feel and sensitive touch; 4. Hydrophobic is easy to clean, and the oil stain is lightly rubbed as new as 5. Bright and high-definition, the phone is still clear in the sun; 6. No foaming, no warping, and the curved screen and the flexible screen can fit perfectly.
