Abstract

dispositivo de exibição a presente invenção refere-se a uma pluralidade de primeiros e segundos circuitos de pixels de sensor sendo cada um percebe a luz durante um período de percepção designado e retém a quantidade de luz percebida de outra forma é arranjada em uma região de pixels. uma luz de fundo é ligada uma vez por um tempo predeterminado no período de um quadro. um período de percepção a1 quando a luz e fundo está ligada e um período de percepção a2 quando a luz de fundo está desligada são ajustados uma vez, respectivamente, no período de um quadro. o primeiro circuito pixels de sensor é reajstado no início do período a1 e percebe a luz no período a1. o segundo circuito de pixels de sensor é reajustado no início do período a2 e percebe a luz no período a2. a leitura dos circuitos de pixels de sensor de dois tipos é realizada em paralelo de uma meneira sequencial de linha durante um período diferente dos períodos a1 e a2 . um circuito de diferença fornecido do lado de fora dos circuitos de pixels de sensor é usado para obter uma diferença entre uma quantidade de luz quando a luz de fundo está ligada e uma quantidade de luz quando a luz de fundo está desligada. dessa forma, é fornecido um dispositivo de exibição que tem uma função de entrada que não depende dos ambientes de luz.
