  • Patent number: 11900712
    Abstract: A fingerprint image capture system comprises an electro-optical material which captures a static fingerprint image and an apparatus for converting the static fingerprint image into an electronic signal. The image capture system includes an electrode for contacting a finger, and a bias supply for creating an electric field where epidermal ridges contact the electro-optical material. A transistor array senses charge or optical density variations in the electro-optical material to create an electronic representation of the fingerprint image. An initialization electrode places the electro-optical material into a uniform condition prior to acquisition of the fingerprint image. A physical artifact of the fingerprint image can be archived by removing the electro-optical material from the system following the fingerprint image acquisition.

    Abstract: A display system and a vehicular head-up display system using the same is disclosed. The display system includes an image generating device, a polarization reflection film, a light-transmitting substrate, a curved wave plate, a curved reflector and a transparent substrate. The image generating device emits polarized light. The curved wave plate adheres to the reflective curved surface of the curved reflector through an optical adhesive. The curved wave plate and the reflective surface have the same curvatures. The reflective curved surface faces towards the polarization reflection film. When the curved reflector reflects the polarized light sequentially passing through the polarization reflection film and the curved wave plate to the polarization reflection film through the curved wave plate, the curved wave plate converts the polarization direction of the polarized light. Finally, the polarization reflection film reflects the polarized light to the transparent substrate to generate a virtual image.
