<p>A cathode ray tube (12) which includes a face-plate (16) having on its inner surface a centrally disposed phosphor screen (18), and a flat color selection electrode (35) supported in tension, spaced from the screen. The electrode (35) has a central apertured portion and a peripheral portion, and is susceptible to vibration. A vibration damping system (62) is located on the peripheral portion of the electrode for damping vibrations in the electrode.</p> |
