  • Patent number: 10719685
    Abstract: A papillary print sensor comprising in superposition a contact surface to which the print to be imaged is intended to be applied, an array optical sensor and illuminating device. The illuminating device is arranged between the contact surface and a detecting surface of the array optical sensor, and consists of a plurality of organic light-emitting diodes, referred to as OLEDs. Each OLED extends uninterruptedly over more than a third of a width (L1) of the detecting surface, and the OLEDs extend together along one or two series of patterns that are parallel to one another and distributed along the length (L2) of the detecting surface. This configuration of the OLEDs allows in particular the transistors for controlling the OLEDs to be placed off the detecting surface (125).
