Simulation Designing and Experiment of Low Aberration Lens Systems for Color Display Tubes (Special Issue on Electronic Displays)

概要

論文の詳細を見る
To improve the resolution of the color CRTs, we propose a new electrostatic lens system which has two additional electrodes between the focus electrode and the anode electrode. The anode voltage and focus voltage are supplied on these additional electrodes. The numerical simulation shows that the system can reduce the third order aberration coefficients almost up to 31% of the conventional system. And the experiments show that the typical beam spot diameter is improved by nearly 20% of the conventional system.
