Abstract

UN CIRCUITO CONTROLADOR DE DATOS (25) Y UN PLAN DE CONTROL DEL SISTEMA QUE SE PUEDE INTEGRAR DIRECTAMENTE EN UN SUSTRATO DE VISUALIZACION (149 PARA REDUCIR EL COSTE DE LOS CIRCUITOS INTEGRADOS PERIFERICOS Y EL MONTAJE HIBRIDO REQUERIDOS POR LOS PANELES DE CRISTAL LIQUIDO DE MATRIZ ACTIVA SIN EXPLORAR PARA CONECTARLAS AL SISTEMA. EN EL PANEL (14) SE DEPOSITA UN CIRCUITO DESMULTIPLEXADOR (102) PARA DESMULTIPLEXAR UN GRUPO DE Y COLUMNAS DE SEÑALES DE ENTRADA DE DATOS DE VIDEO MULTIPLEXADAS HACIA X GRUPOS DE Y CAPACITORES DE PIXELS (94, 96...100) QUE TAMBIEN SE ENCUENTRAN DEPOSITADOS SOBRE EL SUSTRATO (14) EN Z FILAS. ADEMAS, UN CIRCUITO CONTROLADOR DE DATOS (12) GENERA SEÑALES DE TENSION PARA PRECARGAR LOS CAPACITORES DE PIXELS (94, 96...100) A UN PRIMER NIVEL DE TENSION DURANTE UN PRIMER PERIODO DE TIEMPO DE TAL MODO QUE LAS SEÑALES DE ENTRADA DE DATOS DE VIDEO ACOPLADAS A LOS MISMOS DE FORMA MULTIPLEXADA HAGAN QUE LOS CAPACITORES (94, 96...100) QUEDEN ALMACENADOS A UN SEGUNDO NIVEL DE TENSION PREDETERMINADO DURANTE UN SEGUNDO PERIODO DE TIEMPO PARA GENERAR UNA REPRESENTACION DE VIDEO A MEDIDA QUE LAS FILAS DE PIXELS SON SECUENCIALMENTE EXPLORADAS.
