Abstract
Un haz de electrones tiene a inclinarse hacia abajo a medida que se desvía horizontalmente para formar una trama en un aparato de exhibicion de vídeo. La inclinacion del haz puede ocasionar errores geométricos en la trama, por ejemplo, errores de ortogonalidad y de paralelogramo. Un circuito de correccion de trama (100) desvía substancialmente la inclinacion descendente del haz de electrones modulando una corriente de deflexion vertical (Iv) con una corriente de correccion de régimen horizontal inducida (ICORR), eliminando así substancialmente los errores de ortogonalidad, y paralelogramo en la trama. En modalidades respectivas de un arreglo inventivo enseñado en la presente, se induce la corriente de correccion de trama de régimen horizontal (ICORR) en las bobinas de deflexion verticales (Lv1, Lv2) acoplando magnéticamente una forma de onda de pulsos de filamento (11), una forma de onda de voltaje de deflexion horizontal, una corriente de deflexion horizontal en las bobinas de deflexion vertical (Lv1, Lv2).
