Abstract

La présente invention concerne un procédé d'affichage, qui est applicable à un dispositif terminal. Le dispositif terminal comprend au moins deux zones d'affichage, et un composant de reconnaissance d'empreinte digitale est disposé sous une première zone d'affichage desdites zones d'affichage. Le procédé consiste : à obtenir une instruction de déclenchement de détection d'empreinte digitale, et à commuter une première interface d'affichage affichée dans la première zone d'affichage à une interface de détection d'empreinte digitale prédéfinie sur la base de l'instruction de déclenchement de détection d'empreinte digitale. L'invention concerne également un dispositif d'affichage et un support de stockage informatique.
