ABSTRACT:
An improved vertical and horizontal deflection electrode system for an electrostatic deflection cathode ray tube which comprises a glass bulb and an electron beam source and vertical and horizontal deflection electrodes formed in patterns and which are applied to the inner surface of the glass bulb and wherein the ratio of the area of the vertical deflection electrodes to the area of the horizontal deflection electrodes is selected to be approximately equal to the deflection aspect ratio of the electron beam and the horizontal and vertical directions which results in the voltage required in the deflection system being substantially decreased.
