Fingerprint identification device and fingerprint identification method

A fingerprint identification device and a fingerprint identification method are provided. The fingerprint identification device includes a self-emitting display panel, a fingerprint sensor and a processor. The self-emitting display panel displays at least one light pattern in a sensing region. The fingerprint sensor senses a finger object located above the sensing region of the self-emitting display panel to generate a first fingerprint image and a second fingerprint image corresponding to the at least one light pattern. The processor is coupled to the fingerprint sensor. The processor determines whether the first fingerprint image and the second fingerprint image have opposite tones to identify the finger object is a real finger or a fake finger.

An optical module includes: an infrared light emitter configured to emit infrared light; an infrared light receiver configured to receive the infrared light emitted from the infrared light emitter and generate a signal based on an amount of the received infrared light; a touch interface arranged between the infrared light emitter and the infrared light receiver, and configured to reflect the infrared light emitted from the infrared light emitter toward the infrared light receiver, and change an amount of the reflected infrared light as a touch input occurs; and a visible light emitter configured to emit visible light toward the touch interface such that the visible light is emitted outside the optical module by passing through the touch interface.

VEHICLE CONTROLLING APPARATUS AND VEHICLE HAVING THE SAME

Disclosed is a vehicle controlling apparatus for controlling a vehicle having a display. The vehicle controlling apparatus includes: a communication unit configured to communicate with the display; and a processor configured to set at least one region among an entire region of the display as a display region, based on a sight line range changed according to a position of a passenger who got on the vehicle, and configured to control the communication unit so that visual information is displayed on the display region.

DETECTION DEVICE AND PROGRAM

A detection device includes: a detection unit that detects a predetermined non-contact operation by a detection reference; and a control unit that changes the detection reference when the predetermined non-contact operation is not detected by the detection reference.

Self-Mixing Interference Based Sensors for Characterizing Touch Input

Disclosed herein are electronic devices having touch input surfaces. A user's touch input or press on the touch input surface is detected using a set of lasers, such as vertical-cavity surface-emitting lasers (VCSELs) that emit beams of light toward the touch input surface. The user's touch causes changes in the self-mixing interference within the VCSEL of the emitted light with reflected light, such as from the touch input surface. Deflection and movement (e.g., drag motion) of the user's touch is determined from detected changes in the VCSELs' operation due to the self-mixing interference.
