Abstract

RECURSO DE REALIZAçãO DE CIRCUITO DE DRIVER DE DISPLAY EM MODO DE CORRENTE A invenção compreende dispositivos e métodos para o acionamento de um pixel MEMs, e em particular, um pixel do modulador interferométrico. Em uma modalidade um dispositivo para modulação de luz inclui um modulador de luz incluindo um elemento ótico móvel posicionado em duas ou mais posições, o modulador operando de forma interferométrica para exibir uma resposta ótica predeterminada diferente em cada uma das duas ou mais posições, e o conjunto de circuito de controle conectado ao modulador de luz para controlar o dito modulador interferométrico, onde o conjunto de circuito de controle é comutável de forma controlada entre duas configurações de circuito, e onde o conjunto de circuito de controle provê corrente para o dito modulador de luz quando comutando entre as duas configurações de circuito para fazer com que o elemento ótico móvel do modulador de luz se mova entre duas posições de suas duas ou mais posições. Em outra modalidade um método de acionamento de um pixel do modulador interferométrico com um circuito de acionamento inclui o provimento de uma diferença de potencial através do pixel interferométrico, em que a diferença de potencial provida aumenta durante um período de tempo, e alterando a posição de uma camada refletora móvel do pixel interferométrico com base na diferença de potencial provida.
