Color display device with deflection means and a co-operating pair of means for influencing the distance between electron beams |
摘要 |
A color cathode ray tube has quadrupole elements which increase and decrease the distance between the electron beams as a function of the deflection. Two co-operating elements have their windings connected in series with each other to minimize dissipation in the driving circuits. One driving circuit provides a common current which flows through both quadrupole elements, while another driving circuit provides a difference current to a node between the quadrupole elements.
