Digitimes Research believes that global shipments of small- to medium-size panels will decrease from 2.647 billion units in 2017 to 2.189 billion units in 2021 or a CAGR of negative 4.6%. This will be caused by a shift to AMOLEDs in the smartphone market. Although LCDs will decline, the company believes that the overall handset market will grow from 2.545 billion units in 2017 to 2.757 billion in 2021, a CAGR of 2.0%.
