Abstract

PANTALLA DE BARRIDO DE CRISTAL LIQUIDO CON REDUNDANCIA DE BARRIDO SELECTIVA. UNA PANTALLA (10) DE DISPOSITIVO DE CRISTAL LIQUIDO (LCD) INCLUYE UNA REJILLA DE LINEAS SELECTIVAS DE FILAS CONDUCTORAS Y LINEAS DE DATOS EN COLUMNA QUE SE UTILIZAN JUNTO CON TRANSISTORES DE LAMINA DELGADA (TFT) PARA DIRIGIR UN ELECTRODO DE PIXEL EN LA PANTALLA. LA PANTALLA LCD (10) INCLUYE DOS REGISTRADORES DE IMPULSO (18, 18'') PARA LA RECEPCION Y PROPAGACION DE SEÑALES SELECTIVAS DE LAS LINEAS SELECTIVAS DE LA FILA, TENIENDO CADA REGISTRADOR DE IMPULSO UNA PLURALIDAD DE FASES REGISTRADORAS DE IMPULSO (S) CONECTADAS A CADA LINEA SELECTIVA DE FILA. SE PROPORCIONA UNA PLURALIDAD DE CIRCUITOS COMBINADORES (C), UNO POR CADA FASE (S) DE CADA UNO DE LOS REGISTRADORES DE IMPULSO (18, 18''). CADA CIRCUITO COMBINADOR (C) ESTA CONFIGURADO PARA PROPORCIONAR UNA RUTA DE CONDUCCION ELECTRICA PARA LA SEÑAL SELECTIVA ENTRE FASES SUCESIVAS (S) EN CADA UNO DE LOS REGISTRADORES DE IMPULSO (18, 18''). CUANDO SE DETECTA UN FALLO EN LAFASE (S) DE UNO DE LOS REGISTRADORES DE IMPULSO, EL CIRCUITO COMBINADOR (C) ACOPLADO A LA SALIDA DE LA FASE DEFECTUOSA (18D) ES RECONFIGURADO PARA DIRIGIR LAS SEÑALES SELECTIVAS (27) DESDE LA FASE CORRESPONDIENTE (18L) DEL OTRO REGISTRADOR DE IMPULSO (18'') A LA SIGUIENTE FASE (18E) DEL REGISTRADOR DE IMPULSO (18). SE PROPORCIONA REDUNDANCIA DEL REGISTRADOR DE IMPULSO SELECTIVO COMPLETA, INCLUSO SI AMBOS REGISTRADORES DE IMPULSO (18, 18'') TIENEN FASES DEFECTUOSAS.
