近日，不少网友在社交平台吐槽"折叠屏被冻坏了""折叠屏到了东北就是碎碎冰"，尤其随着冰雪旅游季的到来，该类话题讨论热度不断升温。 智通财经搜索相关社交平台发现，有不少网友吐槽。一位北京网友吐槽说，"北京最近下雪其折叠屏手机在车里放了几小时，拿出来一展开屏幕就听见咔咔 玻璃碎了的声音，然后就漏液了。"从网友配发的相关图片看，手机打开折叠屏变成了"极光色"。有网友晒出折叠屏手机的开箱提示，其中一条提醒：低至 零下5度请勿弯折手机；网友调侃"折叠屏真的很脆弱……"。 据极目新闻报道，记者致电多家手机品牌授权维修店。一名工作人员表示，"现在很多人都知道折叠屏手机在低温室外不要打开了，手机开箱时也有注意事 项提醒温度太低时不要折叠"。另一名其他品牌的工作人员称，在东北室外使用折叠屏手机时尽量不要折叠，"进入室内后最好先缓一缓焐热了再用，不然冻 时间长了屏幕容易坏，建议温度零上时使用折叠屏"。 折叠屏手机如何避免"冻伤"？据科技日报2025年12月报道，北京理工大学计算机网络攻防对抗技术研究所所长闫怀志告诉记者，"折叠屏不耐低温的核心在 于材料物理特性的改变。"据其介绍，折叠屏采用的柔性OLED屏幕由多层高分子材料、有机 ...

Group 1 - The core issue with foldable screens is their vulnerability to low temperatures, which can cause the materials to become brittle and lead to screen damage [1][2] - Foldable screens are made of flexible OLED technology, which includes multiple layers of polymer materials, an organic light-emitting layer, and ultra-thin glass (UTG), all of which have a glass transition temperature that affects their performance in cold conditions [1][2] - The industry is actively working on improving foldable screen technology by focusing on material enhancements and structural optimizations, such as developing low glass transition temperature flexible substrates and more resilient low-temperature UTG [2] Group 2 - In low-temperature environments, foldable screens can experience three main issues: material brittleness, hinge stiffness due to solidified lubricants, and functional disruptions like touch sensitivity loss and battery performance decline [2][3] - Users are advised to take precautions to prevent foldable screens from freezing or cracking, including using insulated phone cases and keeping devices close to their body for warmth [2][3] - It is recommended that users minimize outdoor opening and closing of the device and allow the phone to acclimate to temperature changes before use to avoid potential damage [3]
