ABSTRACT:
A field correction element (30) is provided in the peripheral field of a focusing lens of an electron gun system of a color display tube to reduce the potential differences between the electrodes of the focusing lens necessary for horizontal and vertical focusing, respectively. The field correction element (30) consists of a plate (31) which extends substantially perpendicularly to the electron beams and has elongate or square apertures (32, 33, 34) through which the electron beams (6, 7, 8) pass. It is also possible to perform convergence corrections by means of such a field correction element.
