In recent years OLED technology has emerged as the leading smartphone display technology, and the world's most popular phone vendors are all shipping AMOLED smartphones.
In 2018, over 500 million AMOLED screens were produced - mostly to satisfy demand from mobile phones vendors. The smartphone OLED 2018 market was led by Samsung, who has been using AMOLEDs in its high-end phones for many years, followed by Apple, LG, Xiaomi, Huawei and others. Samsung is branding its smartphone OLED displays as Super AMOLED display.
