Abstract
resumo sistema de controle redundante para lcd numa forma de realização exemplar, cada condutor horizontal e vertical de uma matriz de tft podem estar em contato eléctrico com um primeiro e segundo sistema de controle. inicialmente, toda a tela é conduzida pelo primeiro sistema de controle. quando/se ocorrer uma falha no primeiro sistema de controle, ele é desligado e o segundo sistema de controle mantém o funcionamento de todo o visor. cada sistema de controle pode conter um conjunto de drivers de origem/portão, placa de interface de exibição, e fonte de alimentação. um botão reversível pode permitir que o usuário alterne manualmente entre sistemas de controle. alternativamente, a falha pode ser detectada pelas placas de interface de exibição ou um processador gráfico.
