We have developed transparent fingerprint sensors applying the LTPS (low-temperature polysilicon) backplane technology and touch panel technology for smartphones. We are able to realize the next generation of fingerprint sensor devices, for large screen sensors, transparent sensors and flexible sensors, which are not possible with silicon based fingerprint sensors.
We have also developed a thin image sensor that allowed for both high-speed readout and high-resolution imaging.
Integrating LTPS thin-film transistors with high mobility and high-sensitivity organic photodectors has enabled to create a single sensor that measures not only pulse wave distribution, which requires high-speed readout, but also biometric information, such as fingerprints and veins, which require high-resolution imaging.
