TrendForce identifies viscoelastic optically clear adhesive (OCA) as key to hiding the crease on Apple's upcoming foldable iPhone. The glue stays soft during bends to cut stress fatigue and stiffens under impacts. Apple rejected Samsung prototypes for visible creases, then optimized neutral layer positioning, stress distribution, and variable-thickness glass per patents. OCA stabilizes layers and cuts light scattering. TrendForce projects 20% foldable market share for Apple this year.

TrendForce analysts pinpoint an advanced optically clear adhesive (OCA) as pivotal to Apple's near-invisible crease on its upcoming foldable iPhone. The glue's viscoelastic properties allow it to remain soft during bends, reducing fatigue stress, while stiffening under impacts for added support.

Apple rejected multiple Samsung display prototypes over visible creases, stemming from neutral layer misalignment in the panel stack. Designers addressed this last year through precise stress distribution, optimized neutral layer positioning, and variable-thickness ultra-thin glass—thinner at the fold axis, thicker elsewhere for durability, as detailed in Apple patents.

The OCA further stabilizes the neutral layer and fills microscopic gaps, minimizing light scattering that highlights creases. TrendForce notes these combined innovations enable Apple's entry into foldables. The firm projects Apple capturing 20% of the foldable smartphone market this year, according to reports citing the analysts.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.

Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.

Any contribution is appreciated. If not, no pressure. Thanks for reading.
