to Meet the challenge of doubling the screen of a mobile phone began where I began, by achieving a flexible substrate on which to build a screen as such. But it was soon extended to the coating of said screen. Once the panel is bent down, it was time to protect it, and the first choice of Samsung to your Fold was the opt for the plastic. Specifically, the polyimide.
No, not the confundais with the polyamide. Here we talk about a polymer composed of repeating units of the imide with excellent mechanical properties and resistance to temperature and chemicals. And, in last instance, flexible plastics. But the feel of this polyimide or PI is the one who is and Samsung, after the problems of the Galaxy Fold and repairs, seems to have decided to take a step forward and discover the world of glass.
Goodbye to the polyimide, hello to the crystal of 30 micrometers
The sheet of plastic that covers the screens of the current Samsung Galaxy Fold is supplied by the japanese manufacturer Sumitomo, and although this manufacturer is not directly responsible for the errors of the first units of the Fold (they were due to the design of the lamina propria and the parts left uncovered), it seems that Samsung has decided to leave the material behind and take the glass.
we Associate the word crystal with a rigid material, and that fracture when you fold it, but it seems that this happens only when we talk about sheeting at least 100 micrometers thick, that are the usual that are used in mobile phones. Dolnsys, a chinese manufacturer, have developed a glass of only 30 micrometers and flexible, and Samsung what would you choose for the coating of their future Galaxy Fold 2 and successive models.
The existence of this new glass flexible would not only Samsung could benefit from it for their mobile flexible, but also the rest of the industry. Hence, the koreans are supporting the manufacture of these panels with investment and machinery for Dolnsys, so that you can guaranteed for a good part of its production in exclusive for the near future, if not 100% the same. It is expected, therefore, that a possible Samsung Galaxy Fold 2 that we saw arrive in 2020 to land with a coating of crystal for flexible display.
