Abstract

resumo patente de invenção: "método de ajuste de monitor de cristal líquido e aparelho para o mesmo". a presente descrição refere-se a um método de ajuste de um monitor de cristal líquido e um aparelho, de modo a aperfeiçoar o brilho do monitor de cristal líquido. o método inclui: a mudança de uma voltagem de carga através de um circuito de fonte do monitor de cristal líquido, e a medição das transmissões do monitor de cristal líquido em diferentes voltagens de carga; a determinação de uma voltagem de carga correspondente a uma transmissão máxima do monitor de cristal líquido de acordo com uma relação correspondente entre a voltagem de carga e a transmissão; e a determinação de uma voltagem de operação do circuito de fonte de acordo com a voltagem de carga correspondente à transmissão máxima e ajuste da voltagem de carga através do circuito de fonte para a voltagem operacional. a presente descrição pode aumentar a transmissão do monitor de cristal líquido pelo ajuste de uma voltagem de operação do circuito de fonte para uma voltagem correspondente à transmissão máxima do monitor de cristal líquido, e então o aumento do brilho do monitor de cristal líquido, onde o brilho do monitor de cristal líquido pode ser aumentado sem mudar a estrutura do monitor de cristal líquido.
