Title
(EN) OPERATION OF A DEVICE COMPRISING A LIGHT EMITTING DIODE
(FR) FONCTIONNEMENT D'UN DISPOSITIF COMPRENANT UNE DIODE ÉLECTROLUMINESCENTE
Abstract
(EN)
A method (100) for operating a device comprising a Light Emitting Diode (LED) display is disclosed. The method, performed in the device, comprises obtaining a representation of temperatures to which different areas of the display are subjected (110), generating a display heat map from the obtained representation (120), and managing the luminance of the different areas of the display on the basis of the display heat map (130). Also disclosed are a device (900, 1000) and a computer program configured to carry out a method for operating a device.
(FR)
L'invention concerne un procédé (100) pour faire fonctionner un dispositif comprenant un affichage à diodes électroluminescentes (DEL). Le procédé, réalisé dans le dispositif, comprend l'obtention d'une représentation de températures auxquelles des zones différentes de l'affichage sont soumises (110), la génération d'une carte de chaleur d'affichage à partir de la représentation obtenue (120) et la gestion de la luminance des zones différentes de l'affichage sur la base de la carte de chaleur d'affichage (130). L'invention concerne également un dispositif (900, 1000) et un programme d'ordinateur configurés pour réaliser un procédé pour faire fonctionner un dispositif.
