Abstract

PROCEDIMIENTO Y DISPOSICION DE CIRCUITO PARA INDICAR EL FUNCIONAMIENTO DEFECTUOSO DE LINEAS DE ALIMENTACION DE ELECTRODOS DE SEGMENTOS. CONSISTE EN APLICAR A TODOS LOS ELECTRODOS LCD UNA SEÑAL DE CONTROL ALIMENTADA DE FORMA REDUNDANTE QUE SE SUPERPONE A SEÑALES UTILES APLICADAS A LOS ELECTRODOS DE SEGMENTOS (2) Y A LOS ELECTRODOS POSTERIORES (14), DE MODO QUE EN EL CASO DE INTERRUPCION DE UNA SEÑAL UTIL (18) ENTRA EN ACCION LA SEÑAL DE CONTROL (20) EN LOS ELECTRODOS LCD AFECTADOS, DONDE LA DISPOSICION PARA LA APLICACION DE UNA SEÑAL DE CONTROL (20) SEPARADA ESTA PROVISTA DE UNA LINEA DE ALIMENTACION (7) DE ALTO VALOR OHMICO QUE ESTA CONDUCIDA CONJUNTAMENTE A TODOS LOS ELECTRODOS LCD SIN DISTINCION EN CUANTO A CONEXION DE SEGMENTO O CONEXION DE ELECTRODO POSTERIOR.
