Samsung receives an exclusive license of technology to maintain smoke repellent, dustproof, anti-fingerprint, anti-reflection for 3 years

We found that Samsung Electronics got an exclusive license from Oak Ridge National Laboratory (ORNL) for "super water repellent" technology on smartphones and tablet displays.

Samsung's future smartphones could pack superhydrophobic displays, new patent licensed

By coating the surface of the display with a porous glass film made of a thin nanostructured layer, this technology maintains "water repellency", "dustproof", "suppress light reflection" and "fingerprint protection" for 3 years thing.

"Super water repellency" is a phenomenon in which water droplets are in contact with the surface at an angle exceeding 150 degrees. In this ORNL coating, since the contact angle is from 155 degrees to 165 degrees, the water droplet also scatters on the glass surface . The situation can be seen in the following movies.

Water droplets are dripping on the surface of the glass coated by the researcher.


However, it is not cloudy on the surface. Even this, since water droplets are dripping one after another from the top, water droplets falling on the surface will fly around with the garbage in the surroundings and fly away, so it is hard to get dirty.


When it is not tilted, it looks like this, the water droplet is almost spherical.


The glass panel after coding is like this.


Technology is expected to be of great use not only in electronic equipment but also in other products. Since Samsung licensed this time in electronic equipment, licenses are available for solar panels and windows, for example.
