Abstract
Control plates in flat picture-reproducing devices are located between the cathode and the screen and serve to control the electron flow. Control plates are formed of layers of metal conductors having overlying openings. The width of the openings decreases with depth from both surfaces of the conductors. The openings can be formed by pairs of juxtaposed recesses formed in the sides of adjacent conductors.
Claims11
A control plate for a flat picture-reproducing device, comprising:
- a plurality of conductor layers, each layer being formed of spaced metal conductors having first and second surfaces coplanar with surfaces of the layer;
- openings arranged in a regular pattern in said conductor layers, said openings having a width that narrows with depth from the surfaces of the conductors, said conductor layers being arranged so that the metal conductors of adjacent layers are orthogonal to each other and the openings are superimposed;
- and
- glass frit disposed between said layers for bonding said layers to each other and providing a predetermined spacing between said layers.
