Abstract
(EN)
Provided are a brightness compensation method, a foldable display device and a storage medium. The brightness compensation method is applied to the foldable display device comprising a plurality of sub-screens, the plurality of sub-screens each having an initial brightness value in initial use. Said method comprises: detecting at least two brightness decay values corresponding to at least two co-display sub-screens in a co-display state, the at least two co-display sub-screens together forming a same display interface; determining, on the basis of the at least two brightness decay values, at least two brightness compensation values corresponding to the at least two co-display sub-screens; and performing brightness compensation on the at least two co-display sub-screens respectively according to the at least two brightness compensation values, so as to allow a brightness difference between the at least two co-display sub-screens to be within a preset range, thereby controlling the consistency of the brightness of sub-screens, and ensuring the uniformity of the brightness of the co-display sub-screens.

La présente invention concerne un procédé de compensation de luminosité, un dispositif d'affichage pliable et un support de stockage. Le procédé de compensation de luminosité est appliqué au dispositif d'affichage pliable comprenant une pluralité de sous-écrans, la pluralité de sous-écrans ayant chacun une valeur de luminosité initiale lors d'une utilisation initiale. Ledit procédé comprend les étapes consistant à : détecter au moins deux valeurs de dégradation de luminosité correspondant à au moins deux sous-écrans de co-affichage dans un état de co-affichage, lesdits deux sous-écrans de co-affichage formant ensemble une même interface d'affichage ; déterminer, sur la base desdites deux valeurs de dégradation de luminosité, au moins deux valeurs de compensation de luminosité correspondant auxdits deux sous-écrans de co-affichage ; et réaliser une compensation de luminosité sur lesdits deux sous-écrans de co-affichage respectivement selon lesdites deux valeurs de compensation de luminosité, de façon à permettre à une différence de luminosité entre lesdits deux sous-écrans de co-affichage d'être dans une plage prédéfinie, ce qui permet de commander l'homogénéité de la luminosité des sous-écrans, et d'assurer l'uniformité de la luminosité des sous-écrans de co-affichage.
