| titleOfInvention | The Flat type CRT |
| abstract | The configuration of the present invention is a planar cathode ray tube including a panel having a flat inner and outer surfaces, a rectangular rail attached to the inner surface of the panel, and a slot-type shadow mask attached to the rail to perform color screening of the electron beam and having tensile force. The shadow mask has a " vertical pitch change region " in which the vertical pitch changes above and below the central long axis line,n n n When 1/2 of the size of the vertical effective screen portion is Lv and 1/2 of the size of the horizontal effective screen portion is Lh, the " vertical pitch change area " It is located within 2Lh / 3 of the long axis from the central short axis,n n n The vertical pitch of the outermost long axis is 10% larger than the central long axis.n n n Therefore, according to this invention, the effect of improving the uniformity of the brightness | luminance of a cathode ray tube and the purity characteristic of upper and lower parts of a shadow mask can be acquired. |
