Abstract

UN CIRCUITO DE GESTION DE DATOS Y UN CODIGO DE GESTION DEL SISTEMA QUE SE PUEDEN INTEGRAR DIRECTAMENTE EN UN SUSTRATO DE VISUALIZACION DE LCD PARA ELIMINAR EL COSTE DE CIRCUITOS INTEGRADOS PERIFERICOS Y EL MONTAJE HIBRIDO QUE NECESITAN LAS PANTALLAS DE CRISTAL LIQUIDO DE MATRIZ ACTIVA SIN EXPLORAR PARA CONECTARLAS AL SISTEMA. SOBRE LA PANTALLA SE DEPOSITA UN CIRCUITO DESMULTIPLEXOR PARA DESMULTIPLEXAR UN GRUPO DE COLUMNAS Y DE SEÑALES DE ENTRADA DE DATOS DE VIDEO EN GRUPOS X DE CAPACITORES DE PIXELS Y QUE TAMBIEN SE DEPOSITAN EN EL SUSTRATO EN FILAS Z. ADEMAS SE DEPOSITA SOBRE EL SUSTRATO UN CIRCUITO DE PRECARGA PARA PRECARGAR LOS CAPACITORES DE PIXELS A UN PRIMER NIVEL DE TENSION TAL QUE LAS SEÑALES DE ENTRADA DE DATOS DE VIDEO ACOPLADAS AL MISMO DE FORMA DESMULTIPLEXADA HAGAN QUE LOS PIXELS SE DESCARGUEN A UN SEGUNDO NIVEL DE TENSION PREDETERMINADO PARA GENERAR UNA VISUALIZACION DE VIDEO A MEDIDA QUE LAS FILAS DE PIXELS SE EXPLORAN SECUENCIALMENTE.
