面板产业加速转移，驱动IC全产业链配套发力：近年来国内面板产业链日益成熟，产业加速转移至国内，而驱动IC 作为面板产业链最关键的环节，设计、制造与封测配套环节均依然处于起步阶段。具体数据看：（1）LCD面板，中国大陆LCD面板环节占比超60%，但在DDI设计环节占比低于25%，封测环节比例则更低；与中国大陆情况完全相反，中国台湾在面板环节占比较低，而DDI设计和封测环节占比较高，均超过50%；(2)OLED面板，韩国在OLED面板各个环节具备充分的话语权，OLED面板占比超70%，中国台湾则配套韩国供应链在封测环节占比超过50%，中国大陆OLED面 板环节占比超25%，而在DDI设计以及封测环节占比则较低。

射频前端是手机实现通信功能的核心器件，从2G、3G、4G走向5G时代，一方面由于手机通信制式从针对地区和运营商的特定设计向“全球通”设计转变，另一方面由于射频前端模块中主要组件的用量增加，推动了射频前端单机价值量的增长。根据 Yole Development 的统计与预测，2022年移动终端射频前端市场为192亿美元，到2028年有望达到269亿美元，2022-2028年年均复合增长率将达到5.8%。
