Abstract

La présente invention porte sur un procédé et un dispositif de traitement de crissement dans un dispositif terminal, et sur un terminal, un panneau tactile et un dispositif d'affichage du dispositif terminal partageant un module de pilotage, comprenant : l'acquisition d'un état de fonctionnement du dispositif terminal ; et dans la mesure où il est déterminé que la probabilité que le dispositif terminal soit à proximité des oreilles d'une personne est supérieure à un seuil prédéfini sur la base de l'état de fonctionnement, le réglage de la fréquence d'échantillonnage tactile du dispositif terminal à une fréquence d'échantillonnage prédéfinie, la valeur d'impact de bruit d'un crissement généré entre le panneau tactile et le dispositif d'affichage étant, à la fréquence d'échantillonnage prédéfinie, inférieure à une valeur d'impact prédéfinie. Avec le procédé et le dispositif de traitement de crissement dans un dispositif terminal ainsi que le terminal décrits dans la présente invention, il est possible de déterminer si la fréquence d'échantillonnage tactile du terminal doit être limitée sur la base de différents scénarios d'utilisation dans des applications de premier plan, ce qui permet non seulement d'éliminer ou de réduire l'impact d'un crissement en courant faible sur les oreilles, mais également de ne pas affecter les demandes d'une fréquence d'échantillonnage tactile élevée dans d'autres scénarios d'utilisation.
