Latest Patents

Chun-Jen Wei holds a patent for a "Thin, multi-lens, optical fingerprint sensor adapted to image through cell phone displays." This invention features a multiple-lens optical fingerprint reader designed to read fingerprints through a display. The device includes a spacer and an array of microlenses with both concave and convex surfaces. Each microlens focuses light from a finger adjacent to the display, forming an image on associated photosensors within an image sensor integrated circuit. The method of verifying a user's identity involves illuminating the user's finger with an OLED display and focusing light through the microlenses onto a photosensor array. This process allows for the reading of overlapping electronic fingerprint images, which are then analyzed for feature extraction and comparison against a library of authorized users.
