2021 年Q4 全球面板廠在Q3 復工後產量劇增，尤其是電視用大尺寸液晶面板，因此價格於2021年Q4 遽降，使得主要產地的中國大陸不得不於2022 年初降低產線稼動率。另外俄羅斯入侵烏克蘭，使得東歐消費電子市場下降，也是造成面板價格下滑的原因之一。

In Q4 2021, global panel manufactorers saw a sharp increase in production after the resumption of work in Q3, especially for large-size LCD panels for TV, which causes prices to drop sharply in Q4 in 2021, making mainland China, the main supplier country, to reduce production line utilization rates in early 2022. In addition, Russia's invasion of Ukraine has led to a decline in the consumer electronics market in Eastern Europe, which is also one of the reasons for the decline in panel prices
