Abstract
The invention relates to methods of making color selection deflection electrode structures for use in color picture display tubes having a channel plate electron multiplier arranged adjacent a screen, the deflection electrode structure being disposed intermediate the multiplier and screen and consisting of pairs of elongate, rectangular electrodes aligned with rows of output apertures of the multiplier and operable to control the direction of an electron beam emanating from those apertures so as to impinge upon a selected one of a plurality of different color phosphors in repeating pattern comprising the screen. The methods involve the steps of forming slits (1) in a pair of thin metal sheets, e.g. by etching, to define the required deflection electrodes (3) together with margins (7, 8) and interconnecting supporting strips (4, 5), bonding the two sheets together using an insulative bonding glass material with respective electrodes thereof in registration to form an integral assembly, and rotating the electrodes (3) through around 90.degree. with respect to the plane of the sheets. Spacing elements determine spacing between opposed electrodes and margins.
