Abstract

resumo aparelho de acionamento da tela para acionar uma tela tendo uma luz de fundo e um painel de transmitância um condutor da tela aciona uma tela (101) tendo uma luz de fundo (105) e um painel de transmitância (107) compreendendo elementos de transmitância que modulam a luz da luz de fundo (105). o condutor recebe molduras sequenciais de tempo a ser exibidas. um controlador (115) gera valores da intensidade da luz de fundo para a luz de fundo e valores de acionamento de transmitância para os elementos de transmitância para as molduras sequenciais de tempo em resposta aos dados da imagem para as molduras sequenciais de tempo e uma relação global entre os valores dos dados da imagem e valores da intensidade da luz de fundo e valores de acionamento de transmitância. os valores de acionamento de transmitância compreendem um componente de transmitância desejada e um componente de sobrealimentação. um compensador (117) introduz um valor de compensação de sobrealimentação adaptada localmente aos valores de acionamento de transmitância para gerar os valores de acionamento de transmitância compensada e a luz de fundo (105) é acionada de acordo com os valores da intensidade da luz de fundo e o painel de transmitância (107) é acionado de acordo com os valores do acionamento de transmitância compensada. a adaptação pode, por exemplo, ser para variações de temperatura ou variações de tempo.
