<p>A television receiver is disclosed which includes a cathode ray tube having first and second cathodes, control grids and a fluorescent screen, a circuit for applying a first video signal to the first cathode such that the first cathode emanates a first electron beam in response to the first video signal, a circuit for applying a second video signal to the second cathode such that the second cathode emanates a second electron beam in response to the second video signal, a deflection device for horizontally and vertically deflecting the first and second electron beams from the first and second cathodes simultaneously and a deflection compensating device provided between the pair of cathodes and the fluorescent screen for making the second electron beam impinge upon the fluorescent screen between the first electron beam such that the second electron beam forms a visual display with 1/2 line interval apart from a visual display formed by the first electron beam in the vertical direction.</p> |
