Abstract
(EN)
A fingerprint recognition apparatus and an electronic device, being able to determine the position of a fingerprint pressed by a finger, improving the success rate of fingerprint recognition. The fingerprint recognition apparatus is configured to be provided below the display screen of an electronic device. Said apparatus comprises at least one fingerprint recognition module, and a pixel array in the fingerprint recognition module comprises a plurality of first pixels, the plurality of first pixels being used to sense a red light signal when a finger presses a fingerprint detection area of the display screen, wherein the red light signal is used to determine a fingerprint area pressed by the finger on the fingerprint detection area, and an optical signal sensed by a pixel corresponding to the fingerprint area is used for fingerprint recognition.

La présente invention concerne un appareil de reconnaissance d'empreinte digitale et un dispositif électronique, qui sont aptes à déterminer la position d'une empreinte digitale pressée par un doigt, améliorant le taux de réussite de la reconnaissance d'empreinte digitale. L'appareil de reconnaissance d'empreinte digitale est configuré pour être disposé sous l'écran d'affichage d'un dispositif électronique. Ledit appareil comprend au moins un module de reconnaissance d'empreinte digitale, et un réseau de pixels dans le module de reconnaissance d'empreinte digitale comprend une pluralité de premiers pixels, la pluralité de premiers pixels étant utilisés pour détecter un signal de lumière rouge lorsqu'un doigt presse une zone de détection d'empreinte digitale de l'écran d'affichage, le signal de lumière rouge étant utilisé pour déterminer une zone d'empreinte digitale pressée par le doigt sur la zone de détection d'empreinte digitale, et un signal optique détecté par un pixel correspondant à la zone d'empreinte digitale étant utilisé pour la reconnaissance d'empreinte digitale.
