In 2004, WDI Device responded to the needs of the display and semiconductor industry by unveiling the world’s first Digital Autofocus (ATF) Sensor with Smart Sensor Architecture (SSA). The new technology improved over existing analogue ATF sensors in speed, accuracy and flexibility. Since then, the need for autofocus sensors adaptable to a wide range of complex applications has grown. WDI has risen to this challenge, applying its innovative culture and engineering knowledge to develop a wide variety of ATF technologies and products, spanning many markets.
