自蘋果推出具觸控功能的iPhone以來，對全球的面板產業而言，各家面板廠發展技術不再聚焦於大尺寸面板，而是發展手機用的小尺寸面板。手機的汰換率約比起筆電或桌機螢幕快，更不用比家用電視的使用年限，無異是塊大餅。

Since Apple launched the iPhone with touch function, as far as the global panel industry is concerned, the development technology of various panel manufacturers no longer focuses on large-size panels, but develops small-size panels for mobile phones. The replacement rate of mobile phones is about faster than that of laptops or desktop screens, not to mention the service life of home TVs, which is nothing less than a big pie.
