Abstract

DISPOSITIVO DE REPRESENTACION VISUAL QUE TIENE UN RETICULO DE PIXELS (20), CADA UNO DE LOS CUALES ES SELECTIVAMENTE POSICIONABLE. UN METODO PARA EL FUNCIONAMIENTO DEL DISPOSITIVO CONSTA DE LAS FASES DE RECIBIR UNA SEÑAL QUE REPRESENTA UNA IMAGEN PARA SU VISUALIZACION Y EL DIRECCIONAMIENTO POR MULTIPLEXION EN EL TIEMPO DE CONJUNTOS DE PIXELS, VARIOS TIEMPOS DE DIRECCION POR CADA IMAGEN. LA FASE DE DIRECCION INCLUYE EL ESTABLECIMIENTO DE UN GRUPO DE CONJUNTOS CONSISTENTE EN VARIOS CONJUNTOS ESPACIADOS EN LA SECUENCIA DE DIRECCION DE FORMA QUE LOS CONJUNTOS DEL GRUPO FORMAN UNA SERIE CON LOS CONJUNTOS ADYACENTES QUE TIENEN SEPARACION TEMPORAL EN LA SECUENCIA DE DIRECCION QUE PRESENTA UNA PROGRESION GEOMETRICA, SIENDO EL COEFICIENTE COMUN N UN ENTERO IGUAL O SUPERIOR A 3. LA SEPARACION TEMPORAL ES LA CONSECUENCIA LOGICA DEL ORDEN EN EL QUE LOS CONJUNTOS SE EXPLORAN. ESTA FASE DE DIRECCION AUMENTA EL NUMERO DE LOS NIVELES DE GRIS QUE PUEDEN OBTENERSE.
