苹果推出首款折叠屏手机iPhone Duo，定价1999美元进军市场

苹果公司正式推出首款折叠屏手机iPhone Duo，定价为1999美元345，进入中国折叠屏市场345。三星随即以"欢迎来到折叠屏领域"的讽刺评论回应苹果进入该领域5。

iPhone Duo在硬件设计上采用了多项创新技术。该款手机采用屏下摄像头方案2，屏幕刚性比行业内其他显示屏高40%7。铰链设计是该产品的关键突破，苹果使用AI算法为每一个铰链精确匹配最合适的外壳以确保完美对齐7，并通过3D打印技术制造最多25层定制光敏聚合物微层7。此外，iPhone Duo采用定制可变扭矩铰链设计，由磁铁辅助闭合7，多层显示结构在开合时相对滑动以减少屏幕形变7。机身表面使用特制纳米纹理涂层可显著减少眩光和反射7。

在屏下摄像头技术方面，努比亚副总裁张雷评价苹果的设计方向合理2，并表示这验证了努比亚7年前坚持该技术方向的正确性2。不过张雷指出，苹果首代屏下摄像头在彩色显示下仍有明显痕迹，彩色分辨率为200PPI2，而努比亚Z80U产品已将彩色分辨率提升至400PPI2。

Apple has unveiled its first foldable smartphone, the iPhone Duo, priced at $1,999, marking the company's entry into the competitive foldable device market, particularly in China.345 The device features an innovative foldable glass screen design with significant hardware and software improvements.1

The iPhone Duo incorporates under-display camera technology, a design choice that drew commentary from industry competitors.2 Samsung responded to Apple's late entry into the foldable space with a sarcastic greeting, tweeting "Welcome to Foldables," as the company had already established itself in this category with its Galaxy Z Fold8.56 According to Nubia Vice President Zhang Lei, Apple's adoption of under-display camera technology validates the direction Nubia committed to seven years ago.2 Zhang Lei noted that Apple's first-generation under-display camera shows visible traces in color display at 200 PPI, while Nubia's Z80U model has achieved 400 PPI in color resolution, making the difference imperceptible to the naked eye.2

The device's engineering reflects significant technological investment.7 Apple utilized AI algorithms to precisely match each hinge to its corresponding casing, ensuring perfect alignment.7 The iPhone Duo's screen exhibits 40% greater rigidity compared to other industry displays, addressing durability concerns common in foldable phones.7 The hinge design employs a custom variable-torque mechanism assisted by magnets for closure, while multiple display layers slide relative to each other during opening and closing to minimize screen deformation.7 The phone features a custom nano-textured surface layer to reduce glare and reflection, and its construction incorporates up to 25 layers of custom photopolymer microlayers created through 3D printing.7
