Title (EN) DEVICE AND METHOD FOR IMPROVING LED DRIVING
(FR) DISPOSITIF ET PROCÉDÉ D'AMÉLIORATION DE PILOTAGE DE DEL
Abstract: front page image
(EN) An electronic device (10) comprises a display (12) and a controller (58). The controller (58) is configured to determine a change in a refresh rate of the display (1)2 from a first frequency to a second frequency. The controller (58) is also configured to selectively generate a control signal configured to control emission of a light emitting diode (54) of a display pixel (40) of the display (12) based on the first frequency.
(FR) La présente invention concerne un dispositif électronique (10) qui comprend un dispositif d'affichage (12) et un contrôleur (58). Le contrôleur (58) est configuré pour déterminer un changement de taux de rafraîchissement du dispositif d'affichage (12) d'une première fréquence à une seconde fréquence. Le contrôleur (58) est également configuré pour générer sélectivement un signal de commande configuré pour commander l'émission d'une diode électroluminescente (54) d'un pixel d'affichage (40) du dispositif d'affichage (12) sur la base de la première fréquence.
