ックス型受像管。In a beam index type picture tube that uses a single electron beam and does not use a shadow mask, a slit that is long in the direction parallel to the phosphor stripes on the phosphor surface and short in the vertical direction is made in the beam extraction electrode of the electron gun. A beam index type picture tube, characterized in that the slit is provided to block the spread of the electron beam in the vertical direction of the phosphor stripe.
