For security applications, the new C608 optical fingerprint sensor chip is an ideal solution. It is capable of scanning fingerprints through thick cover glass (2.5D glass or thicker) with high resolution and high performance, making it possible for the industry to achieve clean, button-free designs.

Most of the existing smart phone and tablet displays require cover glass cut-out to accommodate the capacitive fingerprint sensor. For the next generation smart phones and tablets, full top-to-bottom, edge-to-edge displays without any cut-out are highly desired. Glass thinning is necessary for capacitive finger print sensors. Cover glass cut-out or thinning usually adds a significant amount of cost to the manufacture process, as well as weakens the cover glass, resulting in lower manufacturing yields. CMOS Sensor Inc’s C608 optical fingerprint sensor, with the capability of scanning through thick glass including 2.5D cover glass, offers a perfect solution to eliminating glass cut-out or thinning.

The product is specially designed for applications without a lens. It is, thus, possible to make thin profile fingerprint modules for the next generation smart phone or tablet under glass or under OLED display fingerprint sensing. The C608 sensor chip is sensitive to UV, visible & IR. It is capable of scanning fingerprints through thick cover glass and detecting blood flow condition, heart rate, and more.
