7.6-inch Super Retina XDR OLED inner display<\/a><\/strong> and a 5.4-inch outer display. Samsung\u2019s Galaxy Z Fold 8 also features a 7.6-inch inner screen, but its cover display is slightly larger at 5.5 inches.<\/p>\n\n\n\nBoth phones support refresh rates of up to 120Hz<\/strong> and can reach 3,000 nits of peak outdoor brightness<\/strong>. However, their screen proportions are different.<\/p>\n\n\n\nApple has designed the Duo so that its inner and outer displays share the same aspect ratio. This is intended to make the transition between the two screens more consistent when users open or close the phone.<\/p>\n\n\n\n
Samsung instead uses a more square 4:3 inner display<\/strong> and a taller 10:16 cover screen, giving the two screens different shapes and use cases.<\/p>\n\n\n\nApple Uses a Nano-Texture Display<\/strong><\/p>\n\n\n\nOne of Apple’s biggest display differentiators is its custom nano-texture finish<\/strong>.<\/p>\n\n\n\nThe inner Duo display consists of 10 ultra-thin layers and uses the nano-texture surface to reduce reflections and glare. Apple says the finish also contributes to making the fold less visually prominent.<\/p>\n\n\n\n
The company has developed a custom polymer for the nano-textured cover layer, which Apple says is 40% stiffer than materials typically used elsewhere. A scratch-resistant coating is also applied to the surface.<\/p>\n\n\n\n
The under-display FaceTime camera means there is no visible camera cutout interrupting the inner screen.<\/p>\n\n\n\n
Samsung Focuses on Reinforcement<\/strong><\/p>\n\n\n\nSamsung has taken a different approach with the Galaxy Z Fold 8. Its main display uses an anti-reflective coating<\/strong> designed to improve visibility and reduce glare, particularly outdoors.<\/p>\n\n\n\nSamsung has also placed a titanium layer beneath the display and strengthened the shock-absorbing layer to improve resistance to everyday impacts.<\/p>\n\n\n\n
The outer glass uses Corning Gorilla Glass Ceramic 3<\/strong>, while the rear is protected by Gorilla Glass Victus 2. The approach reflects Samsung’s experience refining foldable displays over several generations.<\/p>\n\n\n\nTwo Different Solutions to the Foldable Problem<\/strong><\/p>\n\n\n\nThe two displays ultimately pursue similar goals: reducing reflections, making the crease less noticeable and improving durability.<\/p>\n\n\n\n
Apple is leaning toward custom materials, adhesives and nano-texturing<\/strong>, while Samsung is relying more heavily on structural reinforcement and established display-protection technologies.<\/p>\n\n\n\nThe difference also reflects the companies’ positions in the foldable market. Samsung has spent years refining its Z Fold lineup, while Apple entered the category much later with the benefit of seeing how earlier foldables evolved.<\/p>\n\n\n\n
Summary:<\/strong> The iPhone Duo and Galaxy Z Fold 8 both feature 7.6-inch OLED inner displays with up to 120Hz refresh rates and 3,000-nit peak brightness. Apple differentiates its foldable with a custom nano-texture finish, a 10-layer inner display and an under-display camera, while Samsung uses anti-reflective treatment, titanium reinforcement and tougher protective glass. The two companies are taking different engineering routes to solve the same core foldable-display challenges.<\/p>\n\n\n\nImage Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Apple\u2019s first foldable iPhone Duo and Samsung\u2019s Galaxy Z Fold 8 use similar OLED-based folding displays, but the two companies have taken notably different approaches to reducing glare, improving durability and making the crease less distracting.
