Abstract

patente de invenção: dispositivo de vídeo. a presente invenção refere-se a um dispositivo de vídeo de excelente precisão na captura de imagens, que melhora a linearidade das características de sensibilidade de um fotodiodo. um sensor óptico provido em um substrato de matriz ativa do dispositivo de vídeo inclui: um fotodiodo (d1a) para receber a luz incidente; uma linha de sinal de reconfiguração (rsta) para suprir um sinal de reconfiguração rst ao sensor óptico; uma linha de sinal de leitura (rwsa) para suprir um sinal de leitura rws ao sensor óptico; e um elemento de comutação de sensor (m1a) para leitura da saída da corrente fotoelétrica a partir do fotodiodo (d1a) de acordo com o sinal de leitura, durante um período do suprimento do sinal de reconfiguração até o suprimento do sinal de leitura. um potencial vls de um filme bloqueador de luz (ls) provido no lado traseiro do fotodiodo (d1a) faz com que seja um potencial de nível alto, durante um período que, pelo menos parcialmente, sobrepõe um período enquanto é suprido o sinal de reconfiguração.
