Smartphone display protection by nanotechnology Crystal liquid (www.liquid-kristall.com) was developed in Japan and patented. The production is carried out in Malaysia. The product Crystal brings a protection with the hardness of maximum 9 H on all displays with glass, but not polycarbonate or other materials. It is basically a type of varnish, which dries after applying on a glass surface. What is 9 H? 9 H means fully written out 9hardness and identifies the level of hardness.
9 is the hardest level which can reflect with the hardness scale. A hardness level of 2-3 hours, depending on the quality of the glass reach normal Mobiltelefoneund smartphones. An application of liquid crystal increases the hardness Max up to 9 hours. 3D Systems does not necessarily agree. A Samsung S2 Smartphone has a hardness of 2 H, for the correct application of liquid, Crystal is the maximum achievable hardness 9 h. The hardness levels can not be added (E.g.
2 H from a Galaxy S2 + 9 H by liquid crystal 11 = H). How hard is 9 H actually? A screen on which liquid crystal correct applied, can withstand a tip in the form of a sharp pencil pressure weighing from 0, 75 kg. Scratching may occur are still above 0, 75kg. Ever dull or greater the surface of the acting subject, the higher the pressure intensity might. More information: Crystal 12 hours to reach its maximum hardness, is immediately ready for use after application. After a few minutes the surface reached a hardness, which is accessible by normal stress in daily life more difficult. Always amazing results gave rise to various tests with key, screwdriver, knife or scissors. At very high force or extremely sharp objects, scratches could be observed anyway. Tests on polycarbonate screens negatively have failed. Application of liquid crystal on lenses of cameras can have any adverse effects on the quality of the image.
