摘要： Methods and Apparatuses are provided for a thin high contrast optical acquisition system for fingerprint recognition. In one embodiment, a method of capturing images of a fingerprint may include emitting light from a set of light sources to generate a scattered light from the fingerprint, determining a set of sensor arrays located between an inner boundary and an outer boundary from the set of light sources based on thickness and refractive index of one or more panels between the set of light sources and the fingerprint, activating the set of sensor arrays to capture the scattered light from the fingerprint, and processing the scattered light captured by the set of sensor arrays in parallel to generate a topography of the fingerprint.

摘要： Methods and systems are provided for a multi-level command sensing apparatus that includes a matrix of light sensors and light sources and that may also serve as the display. In one embodiment, a method for performing multi-level command sensing by a multi-level command sensing apparatus comprises detecting a leakage current corresponding to changes of light conditions on a display by one or more light sensors of the multi-level command sensing apparatus, determining an action performed by a user based on the changes of light conditions on the display by a controller of the multi-level command sensing apparatus, determining a command based on the action performed by the controller of the multi-level command sensing apparatus, and executing the command by the controller of the multi-level command sensing apparatus.

摘要： Methods and Apparatuses are provided for a thin high contrast optical acquisition system for fingerprint recognition. In one embodiment, an apparatus for determining validity of a fingerprint includes a light refracting device (light refractor), a light source, a light collecting device, and a controller. The light refracting device can, for example, be a TFT light panel structure or an active matrix organic light emitting diode (AMOLED) panel structure with reverse current measurement and amplification circuitry, and includes an imaging surface and a viewing plane. Incident light from the light source is projected directly or indirectly onto the imaging surface to create an image of the patterned object from the projected light onto the viewing plane. The apparatus is configured to have a thin form factor, which may be flexible or conformable, compared to conventional optical fingerprint acquisition apparatuses.
