Global shipments of smartphone-use TDDI (touch and display driver integration) chips are expected to increase 20% in 2019 from about 414 million units in 2018, according to Digitimes Research.
The supply of TDDI chips fell short of demand in 2018, due to limited available capacity at IC foundries, said Digitimes Research. TDDI chip shipment growth was partly constrained by the tight supply last year.
TDDI chip shipments for 2018 still represented a more than 40% increase compared to 2017, Digitimes Research noted. Suppliers saw their downstream panel customers and smartphone vendors express more willingness to adopt TDDI chips in their devices.
TDDI chip shipments are set to enjoy another increase this year, but growth will decelerate due to a general slowdown in the global smartphone market, Digitimes Research indicated.
Novatek Microelectronics remained the largest supplier of TDDI chips in 2018, followed by Synaptics, according to Digitimes Research.
