Abstract
2.1 EN CONEXIONES DE MANDO CONVENCIONALES, CADA ELECTRODO PIX ACTUA EN CONJUNTO CON UN INTERRUPTOR SEMICONDUCTOR QUE PUEDE ACTIVAR Y DESACTIVARSE. 2.2 SEGUN LA INVENCION, LA CONEXION DE MANDO FUNCIONA EN REGIMEN MULTIPLEX; ES DECIR QUE ANTES O DESPUES DE CONECTAR ADICIONALMENTE LA TENSION DE DATOS CON UN ELEMENTO PIX, SE ACTIVA LA LINEA DE SELECCION DE LA CELDA CORRESPONDIENTE, POR LO QUE LA TENSION DE DATOS SE CONECTA CON LA COLUMNA CORRESPONDIENTE. UN NUMERO DE COLUMNAS SE REUNE EN UN BLOQUE. LA SEÑAL DE VIDEO DE CADA BLOQUE SE TRANSMITE A LAS COLUMNAS CORRESPONDIENTES DEL ELEMENTO INDICADOR Y SE RETRANSMITE POR LOS BLOQUES. 2.3 LA CONEXION ES ESPECIALMENTE APROPIADA PARA INDICADORES LCD Y LA TRANSMISION TELEVISIVA.
