Abstract

"CIRCUITO DE ACIONAMENTO PARA CONTROLE DE BRILHO EM MONITORES DE CRISTAL LìQUIDO E MéTODO PARA O MESMO". Um driver de monitor (10) para uma unidade de monitor (50) possuindo um elemento de memória e uma célula de cristal líquido (20) inclui um primeiro circuito de driver de monitor possuindo um primeiro capacitor de armazenagem (14) e um primeiro amplificador de diferencial (16) acoplado entre o primeiro capacitor de armazenagem e a célula de cristal líquido e um segundo circuito de driver de monitor possuindo um segundo capacitor de armazenagem (14') e um segundo amplificador de diferencial (16') acoplado entre o segundo capacitor de armazenagem e a célula de cristal líquido. O driver de monitor também inclui um primeiro mecanismo de comutação (22 e 24) que permite a comutação do driver de monitor entre o primeiro circuito de driver de monitor durante um quadro positivo e um segundo circuito de driver de monitor durante um quadro negativo e um segundo mecanismo de comutação (26 e 28) acoplado a uma voltagem de suprimento (VDD e VSS). O segundo mecanismo de comutação é controlado por pelo menos uma linha de endereço global (V3 ou V4).
