Abstract

L'invention concerne un procédé de commutation d'écran inter-systèmes. Le procédé comprend les étapes suivantes consistant : à achever, par un premier système, un traitement d'application (S101) ; à préparer, par le premier système, des informations d'intervalle de commutation pour un affichage pour un second système (S102) ; à transmettre, par le premier système, une instruction de commutation de système et les informations d'intervalle de commutation pour un affichage pour le second système au second système (S103) ; à afficher, par le second système, les informations d'intervalle de commutation pour le second système, puis à réaliser une initialisation du second système (S104) ; à afficher normalement par le second système après l'initialisation du second système (S105). Selon le procédé de la présente invention, un écran noir temporaire résultant de la commutation de système peut être évité en affichant les informations d'intervalle de commutation durant un processus de commutation entre deux systèmes, permettant ainsi d'améliorer l'expérience d'utilisateur.
