Like batteries, improving the strength of smartphones screens is part of the technological sea snakes. Many announcements but few concrete results. Some manufacturers like Motorola (Lenovo) even make a communication argument.
We will remember the Moto X Force which "has the most resistant screen in the world" or its patent describing a screen that can repair itself cracks on its surface thanks to heat. A technology that remains theoretical today and described only in a patent. Apple has also devised a dynamic system protecting the screen in the event of a fall, but for the moment at the state of patent also.
The specialist Akhan has developed a screen based on synthetic diamond (technology called Miraj Diamond Glbad) presented as unbreakable (or in any case resistant as ever). The American firm confided to our colleagues in Cnet that a manufacturer has opted for this technology that will equip some of its smartphones in 2019. Without name.
Today, it is the giant Samsung Display that announces having put developed a flexible and "unbreakable" OLED display for smartphones. Noting that the current screens are covered by a layer of glbad "which breaks frequently in case of violent impact", the specialist has developed a fortified but flexible plastic layer covering the OLED panel.
This layer "is particularly suitable for portable electronic devices, not only because of its unbreakable characteristics, but also because of its light weight, conductivity and hardness, all of which are very similar to glbad, "says South Korean.
In order to To prove its point, Samsung is highlighting the certification of Underwriters Laboratories, a control agency that relies on a US federal government agency as well as successful resistance testing by the US Department of Defense. Falls from a height of 1.2 and 1.8 meters did not cause any damage. Ditto for tests of temperature variations (from -32 to + 71 °)
All that sounds promising but Samsung does not specify when this technology will be exploited on a large scale.
