According to the latest data show that in 2017 the world's high-brightness LED chip output is expected to reach 13.179 billion US dollars, an annual growth rate of 2.8%; but from 2018 to 2022, the annual growth rate of the output value will be as high as 2-5%.

2018 to 2022, automotive and display applications CAGR will be 13-15% and 8-11%; and because LED lighting penetration will be close to saturation, lighting application value CAGR will be less than 10%. The global production value of the TV, notebook computers, monitors, and tablet backlight applications will continue to decline slightly in 2018-2022; mobile phone backlighting applications will drop significantly due to the growing popularity of smartphones AMOLED panels.

At the same time, LED chip manufacturers have developed infrared (IR) and ultraviolet (UV) LED chips and micro-LED, but also the development of micro LEDs. Infrared LED chips have been widely used in biometrics (fingerprints, face and iris recognition), ADAS (advanced driving assistance system), and Internet of things (Internet of Things) sensing.

UV-B (wavelengths of 320-400nm) LED chips have been used for industrial and nail curing; UV-B (wavelengths 290-320nm) has been used for skin care; UV-C (wavelengths 240-290nm) has been used for water and air purification and other fields.

Micro-LED chips have begun to be used in fine pixel pitch displays, automotive displays, and high-contrast display backlights, and micro-LED technology bottlenecks still exist, so it may have to wait until 2018 will be truly commercial.
