Abstract
A cathode ray tube comprising a color selection electrode supported in tension. The electrode includes a circumferential portion on which vibration damping means are located for damping vibrations in the color selection electrode. The vibration damping means include a resonator in the form of at least one metal tongue, which is capable of vibrating when the color selection electrode vibrates. The tongue is arranged in, or substantially parallel to, the plane of the color selection electrode. Means are provided to exchange vibration by means of collision and/or friction between the circumferential portion of the color selection electrode and the tongue.
