Abstract

dispositivo de exibição. uma pluralidade de circuitos de pixel de sensor 10 cada um incluindo um fotodiodo d1, um nó de acumulação que acumula carregamento que corresponde uma quantidade de luz, um transistor de leitura m1 que tem um terminal de controle conectado ao nó de acumulação, e transtitores t1 a t4 que ligam e desligam em concordância com um sinal de relógio clk, e que comutam um trajeto para um corrente que flui através do fotodiodo d1 são dispostos em uma região de pixel 4. em concordância com o sinal de relógio clk, quando uma luz de fundo é ligada, uma corrente flui fora do nó de acumulação, e um potencial no nó de acumulação, e o potencial no nó de acumulação, e um potencial no nó de acumulação se eleva. o circuito de pixel de sensor descrito acima é usado para detectar uma diferença entre uma quantidade de luz a ser incidente quando a luz de fundo é ligada e uma quantidade de luz a ser incident4 quando a luz de fundo é desligada. assim, é fornecido um dispositivo de exibição que tem uma função de entrada que não depende de ambientes de luz.
