It only took a little over ten years for Samsung to come out with a foldable smartphone, or should I say, a line of foldable smartphones? The phenomenon of the foldable screens that are currently the focus of attention was explained by Jason Noh, a key developer of the group of Samsung Display.
The Early Beginnings
The beginnings of the foldable technology in Samsung go back to 2008, when it went on to launch the first Galaxy phones in 2009. At this time, Samsung was developing aspects for the first touch screen phones such as the Pixon and the Omnia.
One of the first issues was to design a hard case for the holder that could be folded while being protected from dust and crumbs. This caused the creation of Pressure Sensitive Adhesive (PSA) that enhanced the display to fold under diverse circumstances.
Breakthrough Materials
Samsung took a giant leap in the flexible screen technology by 2020 when it released the UTG in the Galaxy Z Flip. This new material offered a better, as well as a more luxurious, view when opened, which later was adopted in foldable phones.
The advancement did not even end there. Later in the year 2021 Samsung phones Galaxy Z Fold3 and Z Flip3 are the first to boast water resistance with an IPX8 rating. This was done by incorporating the rubber seal around the liquid to prevent it from affecting the screen.
New Innovations in 2024
Jumping to 2024, Samsung has released the Galaxy Z Fold6 and Z Flip6 with a new “Protect Layer” design. This raises of such things as Shear Thickening Fluid (STF), which provides better protection by changing its viscosity relative to pressure levels and impact experiences.
In this advancement it makes the 6-series foldables the sturdiest yet. Furthermore, these models have particle ingress protection that are rated as IP48 because of advance sweeper technology that does not allow particles to ingress into the device.
Enhancing the Experience
Another progressive step was the connection of the S Pen stylus with the Galaxy Z Fold3, though it was not without problems. Earlier models had used metal plates that hindered the usage of S Pen.
This was done away by Samsung when they opted for a carbon fiber plate and using advanced mathematics to place the digitizer perfectly. This let users to use the S Pen without any issue even when it was placed on the folded side of the screen.
Samsung continues to push the boundaries of foldable technology, constantly improving the user experience. As pioneers in this field, the company remains dedicated to perfecting the foldable display, affirming its position as a leader in smartphone innovation.
