En m\u00eame temps, la commande de type buck-boost assure la compatibilit\u00e9 avec les \u00e9crans LCD petits et grands \u00e0 l\u2019aide d\u2019un seul driver. Cela permet de d\u00e9velopper une conception commune de la carte de commande LCD adapt\u00e9e aux panneaux conventionnels avec les derniers \u00e9crans de grande taille. Ces derni\u00e8res ann\u00e9es, pour am\u00e9liorer \u00e0 la fois la visibilit\u00e9 et le design dans le domaine de l\u2019automobile, les \u00e9crans LCD sont utilis\u00e9s dans un nombre croissant de syst\u00e8mes, y compris les tableaux de bord, les affichages t\u00eate haute et la navigation automobile. En outre, la demande \u00e9volue vers des tailles d\u2019\u00e9cran plus grandes. Ils n\u00e9cessitent un plus grand nombre de LED haute luminosit\u00e9 pour le r\u00e9tro-\u00e9clairage ainsi que des drivers de LED dot\u00e9s d\u2019un fonctionnement multicanal et des fonctions de gradation avanc\u00e9es pouvant emp\u00eacher les effets de scintillement. 
\nEn r\u00e9ponse \u00e0 ce besoin croissant du march\u00e9, ROHM a tir\u00e9 parti de sa technologie de conception analogique de pointe et a incorpor\u00e9 des technologies exclusives \u00e0 ses drivers de LED pour obtenir un fonctionnement sans scintillement et contribuer \u00e0 la conception d\u2019une carte de commande commune. Le BD81A76EFV-M permet aussi aux concepteurs d\u2019utiliser des panneaux LCD de grande taille dans les applications de v\u00e9hicules.
\n\u00ab Le nouveau driver de LED de ROHM permet la flexibilit\u00e9 de conception dans les architectures d\u2019affichages modernes et assure la r\u00e9tro-compatibilit\u00e9, am\u00e9liorant ainsi le rapport co\u00fbts-efficacit\u00e9 \u00bb souligne Stefan Drouzas, directeur du marketing des produits d\u2019affichage automobile de ROHM Semiconductor GmbH.<\/p>\n
