Abstract

SE PROPORCIONA UN APARATO DE VISUALIZACION QUE USA UN PANEL DE VISUALIZACION Y EMPLEA UN CRISTAL LIQUIDO QUE TIENE UNA BIESTABILIDAD O UN RENDIMIENTO DE MEMORIA COMO UN CRISTAL LIQUIDO FERROELECTRICO Y PUEDE VISUALIZAR DATOS DE IMAGEN EN DISTINTOS MODOS DE VISUALIZACION, EN LOS CUALES DIFIERE EL NUMERO DE PIXELS (RESOLUCION), COLOR DE VISUALIZACION, UNIDAD DE PIXEL MINIMA Y SIMILARES RESPECTIVAMENTE. EL APARATO DE VISUALIZACION COMPRENDE: UNA MEMORIA PARA ALMACENAR LOS DATOS DE IMAGEN; UN CIRCUITO DE SALIDA DE DATOS DE ELEMENTO DE IMAGEN (PIXEL) PARA SALIDA DE LOS DATOS DE IMAGEN ALMACENADOS EN LA MEMORIA DE CADA DATO DE PIXEL; UN CONVERSOR, PARA CONVERTIR LOS DATOS DE PIXEL QUE SALIERON DEL CIRCUITO DE SALIDA DE DATOS DE PIXEL, EN DATOS BINARIOS QUE SE VISUALIZAN SOBRE EL PANEL DE DISPLAY; UN CIRCUITO DE SALIDA DE DATOS DE VISUALIZACION PARA CONVERSION DE LOS DATOS BINARIOS CONVERTIDOS POR EL CONVERSOR EN LOS DATOS DE VISUALIZACION CORRESPONDIENTES AL MODO DE DISPLAY Y SALIDA; Y UN CONTROLADOR DE VISUALIZACION PARA PERMITIR QUE LOS DATOS DE IMAGEN, QUE SALIERON POR EL CIRCUITO DE SALIDA DE DATOS DE VISUALIZACION, APAREZCAN SOBRE EL PANEL DE DISPLAY. SE USA UN MULTIPLEXOR COMO CIRCUITO DE SALIDA DE DATOS DE PIXEL. COMO CONVERSOR SE USA UNA RAM EN LA CUAL SE HAN ALMACENADO LOS DATOS BINARIOS.
