今年计划更换手机时，笔者发现某熟悉品牌的主力机型已从曲面屏改为直屏。作为始终偏好直屏设计的 用户，不禁感慨厂商终于回归实用需求，不再执着于曲面屏的"炫技"路线——这一曾被安卓阵营奉 为"高端标配"的设计，正在悄然退出主流舞台。 回溯曲面屏的兴起，2015年三星推出首款双曲面手机Galaxy S6 edge，5.1英寸的弧形屏幕，此后安卓阵 营高端机型纷纷跟风，仿佛只有搭载曲面屏，才能撑起高价定位、彰显产品档次。彼时，曲面屏生产成 本远超普通直屏，且三星作为主要供应商产能有限，厂商需排队抢购、货源紧张，三星也借此赚取了高 额利润。 曲面屏的走红，实则与手机行业追求高屏占比的趋势深度绑定。手机厂商为缩减边框、提升屏占比，连 前置摄像头都采用屏下隐藏设计；而曲面屏更是将这一趋势推向极致，不仅填满正面空间，更向机身两 侧侵占。 但这种"延伸"的实际价值，却经不起检验：侧面新增的显示面积十分有限，且弯曲区域因光线折射，易 出现色彩失真、边缘发绿等问题，影响观影与游戏体验。更让用户头疼的是握持感：曲面屏边框弧度陡 峭，长期握持易产生硌手感；若加装侧面加宽的保护壳，虽能缓解硌手问题，却也让曲面屏的设计意义 大打折扣。 曲面 ...

Core Viewpoint - The trend of curved screen smartphones is declining, with a significant shift back to flat screen designs in the mid to high-end market, particularly among brands like OPPO, iQOO, and Xiaomi [1][2][26]. Group 1: Historical Context of Curved Screens - The first curved screen smartphones were Samsung's Galaxy Round and LG's G Flex, which were more conceptual than commercially successful [3][7]. - Samsung's Note Edge in 2014 marked a significant moment for curved screens, leading to the popularization of the dual-curved design with the S6 Edge [11][12]. - The success of the S6 and S7 Edge established curved screens as a high-end feature, influencing other manufacturers to adopt similar designs [13][19]. Group 2: Issues with Curved Screens - Curved screens have inherent issues such as accidental touches, display edge problems, and increased fragility, which have led to customer complaints [20][28]. - Despite their aesthetic appeal, the practical drawbacks have made flat screens more favorable among consumers [26][30]. Group 3: Economic Considerations - The cost of manufacturing curved screens remains higher than flat screens, impacting repair costs; for example, the repair cost for OPPO Find X7 Ultra's curved screen is ¥1690, while the flat screen of X8 Ultra is ¥1490 [30][32]. - Advances in screen packaging technology allow flat screens to achieve narrow bezels, making them visually appealing without the need for curves [32]. Group 4: Design Trends and Market Shifts - The shift back to flat screens is partly driven by a design language that mimics Apple's aesthetic, emphasizing flat screens and right-angled frames [34]. - The cyclical nature of design trends in the smartphone industry suggests that both flat and curved screens will continue to have their advocates, but the current market favors flat screens for commercial reasons [35].
