- Abstract
- The paper describes the design and development of the 7NP4, a 7-in., 80-kv kinescope which is capable of providing clear, bright, theater-size (15 × 20 ft) television pictures. The development involved solving design problems including: (1) a high-efficiency, low-color-shift, white fluorescent screen; (2) adequate high-voltage insulation; and (3) a gun to provide electrostatic focus of a high-current beam into a small, sharp spot, and magnetic deflection through a relatively narrow angle to conserve deflection power and provide essentially uniform focus over the entire picture area.
