Samsung Shows Engineering Secrets Behind Galaxy Z TriFold

Samsung today launched its new multi-folding form factor, the Galaxy Z TriFold. The device sets a new benchmark in foldable innovation by integrating two differently sized hinges. The company has now given us a closer look at how it brings this bold design to life.

Samsung’s Galaxy Z TriFold undergoes end-to-end innovation for reliable multi-folding

The Galaxy Z TriFold folds in two places, allowing it to switch between a regular smartphone and a tablet-like device. For the uninitiated, the phone features a 10-inch inner display with QXGA+ resolution and a 120Hz refresh rate. There’s a 6.5-inch outer display that lets you quickly access notifications without unfolding the device. It measures just 3.9 mm at its thinnest point when unfolded and 12.9mm when folded.

However, achieving this innovative structure needed improved robotic precision, craftsmanship, and rigorous testing. “The product underwent end-to-end innovation, from technology to manufacturing and testing,” said Samsung. One of the biggest challenges was designing the hinges for the multi-folding mechanism to perform reliably in daily use. The device uses two Armor FlexHinges, assembled through advanced automated systems.

Samsung has also applied a specialized display attachment process and 3D laser scanning. This ensured the device’s surface quality and a seamless viewing experience in the unfolded state. Furthermore, the company has used high-speed CT scanning to analyze the flexible printed circuit board inside the display. This ensured the correct alignment of internal components, which is important for the device’s long-term reliability.

Durability testing also played a big role in the TriFold’s development. The main display undergoes a 200,000-cycle multi-folding test. This is equivalent to folding the device around 100 times a day for five years. Samsung also put the Galaxy Z TriFold through a series of scenario-based evaluations.
