Force Touch and Fingerprint Sensing – Different Solutions

The edge-to-edge, bezel-less viewing space of the Infinity Display means the precious real estate for a physical home key is no longer available. Here, Samsung did follow their two competitors by designing the Galaxy S8 and the Galaxy S8+ with force touch solutions, (3D touch, if you are an Apple fan). On both phones, the force touch is confined to a specific place, right where the physical home keys would have been located.
With both the Galaxy S8 and Galaxy S8+ in our labs, we were able to observe that, while the location was the same, the force touch solutions are different between the two phones. In the Galaxy S8, Samsung uses their own force touch component. The Galaxy S8+, however, employs an STMicroelectronics fingerprint and force touch sensing chip from the Finger Tip product family.
If there were any cost savings gained by not using a separate home key/fingerprint sensor assembly, the larger panel and more pixels of the Infinity Display have still resulted in higher costs. The Galaxy S8 costs are around 40% and 20% higher than the Galaxy S7 and Galaxy Note 7, respectively.
