Abstract

L'invention peut s'appliquer au domaine technique de l'entretien des équipements. L'invention concerne un procédé et un dispositif de déshumidification pour un écran d'affichage à DEL, ainsi qu'un écran d'affichage à DEL et un support de stockage. Le procédé de déshumidification pour un écran d'affichage à DEL consiste à : déterminer si un écran d'affichage à DEL remplit ou non une condition de déclenchement de déshumidification prédéfinie (S101) ; et si l'écran d'affichage à DEL remplit la condition de déclenchement de déshumidification prédéfinie, effectuer une déshumidification par rapport à l'écran d'affichage à DEL (S102). Dans le procédé, la déshumidification est effectuée par rapport à un écran d'affichage à DEL lorsque l'écran d'affichage à DEL remplit une condition de déclenchement de déshumidification prédéfinie, ce qui permet d'effectuer automatiquement une déshumidification par rapport à un écran d'affichage à DEL et d'étendre la durée de vie de l'écran d'affichage à DEL.
