Abstract
En un receptor de television de proyeccion, se conoce el uso de un patron de rejilla de difraccion para definir sobre la pantalla de imagen una multiplicidad de puntos de interseccion para los cuales se determinan valores de correccion de convergencia, se almacenan digitalmente y se usan durante la reproduccion con el proposito de corregir la convergencia. Es un objeto reducir el gasto de tiempo para tal correccion en el lugar de produccion o en el lugar donde se encuentra el cliente y, además, mejorar la correccion de la convergencia en los bordes de la imagen. Primeramente se efectua una pro-correccion o correccion burda en el laboratorio o en la serie piloto usando una primera matriz con un patron de rejilla de difraccion fino con valores de correccion para todos los receptores de un tipo de receptor específico con el fin de determinar los valores iniciales. Subsecuentemente se realiza una correccion final o correccion fina en la produccion en serie individualmente para cada receptor usando una segunda matriz con un patron de rejilla de difraccion burda. En particular, un método para corregir la convergencia en un receptor de television de proyeccion con correccion de convergencia automática.
