Abstract
A 3-in. high-performance YAG projection CRT was developed for a new 48-in. compact rear projection and 72-in. front projection TVs. The paper is about the electron gun for the 3-in. high-performance YAG projection CRT. As a result, on the green YAG phosphor screen, beam spot diameters of 0.065 approximately 0.080 nm at cathode currents of 0.5 approximately 1.0 mA and a focusing luminance of 1.4 X 105 cd/m2 at a cathode current of 1.0 mA and an anode voltage of 29 kV were achieved. Thus, this 3-in. YAG projection CRT paved the way for the compact high luminance high-resolution projection TV.
