In 2021, the output value of Taiwan's precision optical components will drop slightly by 1%, reaching NT$108.9 billion. Among them, the proportion of subdivided mobile phone optical lenses and lenses still ranks first, but the proportion has declined for the first time, mainly because the single customer Huawei is restricted by the United States And mobile phone sales have plummeted. However, with the increasing demand for lenses in applications such as laptops, vehicles, and the Internet of Things, the impact of the overall output value has been slowed down. Looking forward to 2022, under the unfavorable factors such as China's lockdown policy, inflation-induced reduction in consumer spending, and geopolitical tensions, the global demand for major optical terminal applications such as mobile phones and computers will weaken. It is estimated that the output value of Taiwan's precision optical components will decline4 %.
