2021年上半年由於全球疫情逐步趨緩以及各主要經濟體推出大規模的刺激方案，全球經濟需求仍呈現穩健回升的態勢，所以台灣光電產業在2021年上半年的產值較2020年上半年呈現正成長。

In the first half of 2021, due to the gradual slowing down of the global epidemic and the introduction of large-scale stimulus plans by major economies, global economic demand is still showing a steady recovery trend. Therefore, the output value of Taiwan's optoelectronic industry in the first half of 2021 is showing a positive trend compared with the first half of 2020.
