Abstract
(EN)
Disclosed are an optical-type fingerprint recognition display and an operation method thereof. According to the present disclosure, provided are an optical-type fingerprint recognition display and an operation method thereof, the fingerprint recognition display comprising: a display panel; and a processor. The display panel comprises a plurality of pixels arranged in a two-dimensional matrix shape, and the pixels comprise: at least one sub-pixel for emitting light on the basis of a first signal received from the processor; and a light sensor for receiving light, which is emitted from the sub-pixel and is reflected from a fingerprint, to generate a second signal. The processor determines a touch region on the display panel on the basis of information on a position on the display panel, the position being touched by a user, transmits the first signal to one or more pixels included in the touch region, and recognizes the fingerprint of the user on the basis of a second signal received from the pixels.

L'invention concerne un dispositif d'affichage de reconnaissance d'empreinte digitale de type optique et son procédé de fonctionnement. La présente invention concerne donc un dispositif d'affichage de reconnaissance d'empreinte digitale de type optique et son procédé de fonctionnement, le dispositif d'affichage de reconnaissance d'empreinte digitale comprenant : un panneau d'affichage ; et un processeur. Le panneau d'affichage comprend une pluralité de pixels organisés sous forme de matrice bidimensionnelle, et les pixels comprennent : au moins un sous-pixel servant à émettre de la lumière sur la base d'un premier signal reçu du processeur ; et un capteur de lumière servant à recevoir de la lumière, qui est émise à partir du sous-pixel et qui est réfléchie par une empreinte digitale, pour générer un second signal. Le processeur détermine une région de toucher sur le panneau d'affichage sur la base d'informations concernant une position sur le panneau d'affichage, la position étant touchée par un utilisateur, transmet le premier signal à un ou plusieurs pixels compris dans la région de toucher, et reconnaît l'empreinte digitale de l'utilisateur sur la base d'un second signal reçu des pixels.
