Apple's inaugural foldable smartphone, the iPhone Duo, is on the verge of its market debut, and the topic of screen creases has become a focal point of public interest. Recently, Apple executives shed light on the company's strategy for tackling this technological hurdle. The iPhone Duo does not completely eradicate the crease physically; rather, it employs a nano-texture matte screen and system animations to substantially diminish its visual impact. From a standard viewing perspective, the crease is nearly imperceptible, though it remains detectable under side lighting or at certain angles. Apple has adopted a unique nano-texture process to minimize glare and reflections, and it utilizes optically clear adhesive to facilitate the relative sliding of display layers during folding, thereby alleviating stress. Moreover, the iPhone Duo's screen assembly incorporates dual-layer UTG ultra-thin glass, which bolsters rigidity while mitigating the degree of deformation. However, the nano-texture coating also results in a slight reduction in screen transparency, which may cause the display to appear slightly grayish or whitish under intense lighting conditions.
