In 2020, HTFL first introduced a bias-switchable photodetector, which changes its properties when voltage is applied, and has been researching it ever since. This has led to the implementation of various devices such as ADAS, optical logic gates, and filter-free photodetectors. Currently, we are conducting research on innovative devices that can distinguish the color and polarization of light. 

Unlike conventional smartphone image sensors specialized in color differentiation, the field of autonomous driving heavily relies on the use of near-infrared information. HTFL is developing an innovative image sensor capable of receiving both near-infrared and visible light information and separating them into distinct data. Through this technology, we aim to implement next-generation ADAS (Advanced Driver Assistance Systems) for autonomous driving.
