- 論文の詳細を見る
An electromagnetic focusing electron gun was used in high-luminance and high-definition YAG (yttrium aluminum garnet) projection CRT successfully. The dual-focusing system in it was developed, which was composed of electrostatic pre-focusing lens and electromagnetic focusing lens. Result from the special optimization of structure and voltage, the electron gun has excellent characteristics especially wit high current. As a result, on the green YAG phosphor screen, beam spot diameters of 0.065〜0.080mm at cathode currents of 0.5〜1.0mA. So the horizontal resolution was more than 1200 TV-lines on the 3-in projection CRT screen. Meanwhile, the luminance of 1.4×10^5cd/m^2 at cathode current of 1.0mA and anode voltage of 29kv was achieved.
