Abstract

registrador de deslocamento, circuito de transmissão de linha de sinal de varredura fornecido com o mesmo, e dispositivo de exibição. a presente invenção refere-se a um registrador de deslocamento implementado que pode comutar entre ordens de varredura de linhas de sinal de varredura, enquanto suprime um aumento em uma área de circuito, um aumento de consumo de corrente, e uma escassez de carga a uma capacitância de pixel. cada estágio que constitui um registrador de deslocamento (410) inclui um transmissor de película delgada de controle de saída para aumentar um potencial de um sinal de varredura com base em um primeiro relógio (cka), dos transitores de película delgada para aumentar um potencial de um primeiro nó conectado a um terminal de porta do transitor de película delgada de controle de saída, com base em um sinal de varredura emitido de pré-estágio/um último estágio, e dois transitores de película delgada para reduzir um potencial do primeiro nó, com base em um sinal de varredura emitido de um terceiro estágio após/a terceiro estágio antes de um estágio referido. o registrador de deslocamento (410) opera com base em sinais de relógio de quatro fases, inclusive sinais de relógio bifásicos (gck1, gck3) que são fornecidos a estágios de ordem ímpar e sinais de relógios bifásicos (gck2, gck4) que são fornecidos a estágios de ordem par, cujas fases são deslocadas 90 graus de umas das outras.
