There is no scratch resistance, so what is the plastic screen protector for Galaxy Z Flip?

Tram Ho

The question of the Galaxy Z Flip screen has finally been solved when the famous YouTube channel JerryRigEverything completely dissected this device. It turns out the Galaxy Z Flip screen actually has a protective glass, though it’s very thin. And on top of this ultra-thin glass is indeed a flexible layer of plastic, but what does it do when it’s not scratch resistant?

The interview of The Korean news site The Elec with experts from Sekyung Hi-Tech, a supplier of thin plastic film (colorless polyimide: CPI) protecting folding screens for both Galaxy Fold and Galaxy Z Flip, provided an explanation for this mystery.

Why does the Galaxy Z Flip need a protective plastic even though it is not scratch resistant?

According to the interview, despite the fact that it can be bent, the UTG ultra-thin glass is still more fragile than plastic and tends to crack when dropped on hard floors or over-bent.

This is evidenced in the JerryRigEverything clip when the corner of the screen is curved up and even though it is protected by thin CPI plastic, hair-thin cracks still appear on the screen. Imagine what would happen if you dropped this smartphone without a plastic sheet to protect the screen at the time.

That’s why Samsung has to put this protective layer on the Galaxy Z Flip’s ultra-thin glass, although this transparent film is still quite soft and tends to be more prone to scratches than the ultra-thin glass. protection below. Anyway, this is the price to pay for your device to survive the unexpected accident, rather than the deliberate knife incision in the clip.

However, when discovered the ultra-thin glass on the Galaxy Z Flip, JerryRigEverything also found that its scratch resistance is only slightly better than the protective plastic sheet above and still inferior to with tempered glass on regular phones. So why is this glass still equipped for the Galaxy Z Flip?

In fact, the CPI plastic sheet was initially used commonly on foldable phones such as Galaxy Fold, Huawei Mate X or recently launched Motorola Razr, because of its ability to bend and fold. . However, this CPI film often leaves wrinkles in the fold between the screen and its visibility is not as beautiful as glass.

Samsung’s animation shows the glass and plastic to protect the Galaxy Z Flip screen below.

Therefore, Samsung had to add UTG ultra-thin glass on the Galaxy Z Flip screen. Not only does it significantly improve visibility compared to Galaxy Fold, it also helps to minimize wrinkles caused by the center fold of the screen, even when the Z Flip’s folding slot is much closer than the Galaxy Fold.

According to The Elec interview, it is likely that the Galaxy Z Fold 2 released in the future will continue to use UTG protective glass, as well as the protective CPI plastic sheet on top, as with Z Flip. If UTG glass suppliers can expand their production capacity to larger sizes, it is likely that Samsung’s third foldable phone will have an 8-inch screen when opened.

As you can see, with or without protective glass, a plastic sheet on top is still essential for future foldable devices. It may not be as durable and scratch-resistant as what users expect, but with normal usage, it’s probably not a big deal.
