Title (EN) UNIVERSAL BACK LIGHT UNIT CONTROL
(FR) COMMANDE D'UNITÉ DE RÉTROÉCLAIRAGE UNIVERSELLE
Abstract:
(EN) Display backlight units are controlled with a signal. A message has an address header specifying one of an array of backlight units, and instructions for individually controlling each of the backlight units, particularized accordingly. The message is routed from a controller to a first controllable backlight unit of the display, which controllably responds to its corresponding particularized instructions. The message is sequentially routed in order from each backlight unit to the next in a chained ring configuration. Data from the backlight units is similarly routed back to the controller.
(FR) L'invention porte sur des unités de rétroéclairage d'affichage qui sont commandées par un signal. Un message possède un en-tête d'adresse spécifiant l'une d'un réseau d'unités de rétroéclairage, et des instructions pour commander individuellement chacune des unités de rétroéclairage, particularisées en conséquence. Le message est acheminé d'un contrôleur à une première unité de rétroéclairage commandable du dispositif d'affichage, qui répond de manière commandable à ses instructions particularisées correspondantes. Le message est séquentiellement acheminé dans l'ordre de chaque unité de rétroéclairage à la suivante, dans une configuration annulaire en chaîne. Les données provenant des unités de rétroéclairage sont réacheminées de la même façon vers le contrôleur.
