蘋果推出摺疊手機 iPhone Duo 螢幕比例為 √2:1，台師大教授解析數學設計原理

蘋果iphone duo摺疊手機

Quick Look

蘋果於台灣時間10日發表首款摺疊螢幕手機 iPhone Duo，台師大電機系助理教授賴以威指出其內外螢幕比例為 √2:1，設計靈感源自利希滕貝格的等比例縮放紙張規格，強調此比例可實現不同形態下畫面無縫填滿，並非精準值但具工程妥協性。

Why It Matters

蘋果於台灣時間10日舉辦2026秋季發表會，推出首款摺疊螢幕手機 iPhone Duo。台灣師範大學電機系助理教授賴以威在臉書發文解析該機螢幕設計的數學原理。

蘋果2026秋季發表會於台灣時間10日正式登場，本次發表會最重磅的亮點，就是推出首款摺疊螢幕手機「iPhone Duo」。台灣師範大學電機系助理教授賴以威點出新機暗藏的數學巧思，直言往後被孩子問到「學根號有什麼用」，終於有了更科技的答案：iPhone Duo的螢幕比例正是經典的「√2:1」。

賴以威在臉書發文表示，蘋果官網強調新機在摺疊與展開狀態下，內外螢幕比例皆具備高度一致性，能讓顯示內容在不同型態間無縫填滿畫面。這個設計邏輯與日常生活中常見的紙張規格完全相同，正如A4紙對折後變A5、兩張拼接成A3，其長寬比例始終維持不變。

請繼續往下閱讀...

賴以威指出，長寬比為 √2:1的長方形 將長邊對折後比例變為「√2/2:1」，經化簡整理即為「1:√2」，實質上僅是長邊與短邊互換，整體幾何比例依然相同。如果嚴格檢查iPhone Duo的螢幕解析度，會發現其實不是精準的√2，還是有為了工程上妥協的微小差距。

賴以威續指，發明這個比例的數學家叫利希滕貝格（Lichtenberg），相傳他一直在找一種紙的比例，讓「等比例縮放」這件事情變得容易，仔細想想，在沒有螢幕的年代，這真的是一個很重要的需求。

Illustrated ads on mobile phone lock screens are easy to accidentally touch, hindering the use of the elderly

A post about mobile phone lock screen illustrations affecting emergency calls sparked heated discussion. The poster later clarified the fact, but the issue raised concerns about the built-in advertising function of the mobile phone system. The reporter found that the lock screen pictures of many mobile phone brands are turned on by default, the exit button is small and difficult to close, and the elderly are easily disturbed by advertisements when using them. In addition to lock screen pictures, advertisements are embedded in multiple locations in the mobile phone system. Regulatory authorities need to regulate mobile phone manufacturers’ behavior of bundling advertisements into the operating system.
