"PC, server, and graphics demand remains healthy amid supply constraints. While demand remains healthy for PC notebooks, 2Q is likely to track below prior expectations due to severe component shortages related to DDICs and PMICs," said John Vinh, an analyst at KeyBanc. As a result, unit sales for power management devices declined 0.7%, while prices increased 2.8% in the first quarter of 2021, according to Semico. DDICs are also in short supply, hampering shipments for select displays. Cars, industrial equipment, PCs, smartphones, TVs, and other products all incorporate flat-panel displays.
