Deep Dive Teardown of the Samsung Galaxy Z Fold5 SM-F946B Smartphone
Share This Post
The 120Hz Main Display/Touchscreen Subsystem probably has a 'Shock Dispersion layer.' The ID in the BOM is #7.66 - Plastic Tape, Large. The hinge consists of three parts ("Triple Rail structure"), each hinge has four springs and four side mountings by which the hinge is attached to the housing (two for each housing). Additionally, all hinges are screwed to the central element (support/cover) which is not integrated with the housing, it is a separate element that also indirectly serves as the housing. The 120 Hz Secondary Display/Touchscreen Subsystem does not have a 'Shock Dispersion layer'. The 'Shock Dispersion layer' in Main Display is 0.070 mm thick. The Samsung Galaxy Z Fold5 SM-F946B’s Main Display weight is 33.43g (Price: $121.99). The Samsung Galaxy Z Fold4 5G SM-F936BDS’s Main Display weight is 34.43g (Price: $199.23).
The Main Display in the Galaxy Z Fold4 does not have a 'shock dispersion layer', but the weight of both subsystems is similar. Comparing the hinges of both devices, the Fold5 uses a system of three hinges that are identical in construction, while in the predecessor one of hinges was smaller. Both devices use an additional element to which the hinges are screwed (apart from the fact that they are screwed to each of the housings), which serves as a protective element for the hinges and is part of the housing. In the Fold5, the hinges are designed in such a way that the housing folds flat when closed, which previous versions (not only the Fold4) did not have.
